Nairaland GeneralStarting Mode Of Fire Pump by hhm1020(op): 11:18am On Jun 23, 2020
The starting relationship between fire control room and fire hydrant action button is related to the starting form of fire hydrant pump. The starting mode of fire hydrant pump is generally divided into two types. The first one is under the bus system joint control mode. The starting of fire hydrant action button can send its required starting signal to the fire control room console through the linkage interface module next to the fire hydrant, and then output the switch contacts that enable the fire hydrant to start. The second starting mode is to directly output the switch value contact of the fire hydrant action button to the fire hydrant pump starting box. These two starting modes can be used in the actual design. The former mode saves wiring, but it is necessary to program the address code of the fire hydrant linkage module under the bus system to achieve the purpose of monitoring a large number of fire hydrants. The latter one is simple and reliable, but it also needs to return the fire hydrant action signal to the fire control room. The designer can choose according to the actual scale of the project in the specific design. The former start-up method can be used for large-scale projects and complex building forms, and the latter start-up method can be used for small-scale projects.


The self start of the spray pump is to break the glass ball of the pipe network nozzle in each protection area under high temperature, which causes the flow of water in the pipe network, thus the linkage alarm valve pressure switch acts, so as to achieve the purpose of self starting the spray pump. Through the water flow indicator linkage module or alarm valve pressure switch lead to the control room, the fire control room can accurately reflect its action signal, and the control room should be able to directly control the start and stop of the spray pump

What is the function of kitchen delivery pump?


How to deal with kitchen waste? What is kitchen waste? Food waste refers to the food waste produced in the production process of restaurant operators and unit canteens, and the kitchen waste produced in the household life of residents. It mainly includes discarded vegetable leaves, leftovers, leftovers, peel, eggshell, tea dregs, broken bones, etc.

In China, the treatment methods of sludge, waste water and sludge are usually incineration, but the kitchen waste contains organic waste such as peel and leftovers, which has high moisture content and high grease content and is not easy to landfill and incineration. In view of this situation, the kitchen delivery pump of Sanyuan environment plays a greater role. What's the function of kitchen delivery pump?

What is the function of kitchen waste pump? Advantages of kitchen waste pump

1. Pump rotor: nano composite wear-resistant rubber rotor, dry operation resistant, idle time more than 60 minutes, the pump body is solid and durable, long life;

2. Anti gas resistance technology: the self-priming height can reach 9 meters, and the horizontal self-priming can reach more than 100 meters, without the need of drainage tank pump. The gas-liquid self-adaptive integrated tank can effectively eliminate the gas resistance and cavitation phenomenon in the process of air extraction (100 m self-priming), so that the pump device has the gas transmission and infusion functions of pump and compressor at the same time.

3. Gas liquid two-phase sealing technology: the special mechanical seal developed by domestic famous mechanical seal experts is adopted. The sealing surface has unique structure, sufficient lubrication, no air resistance and sufficient cooling medium convection, which can effectively prevent dry grinding, high temperature, cracking and failure of the sealing surface and ensure the normal operation of the pump unit. No blocking, strong trafficability: ordinary plastic bags, woven bags, sand, mud, hair and other debris will not affect the use of the pump.

The original manufacturer and Standard commodities shall be bought. If another brand is replaced, the personnel with experience in bearing shall be consulted to check the table for replacement, so as to adhere to the bearing and load capacity.

Application and repair methods of hydraulic pump plug pump: This paper mainly introduces the application and repair methods of hydraulic pump plug pump. 1 oil supply method of hydraulic pump

The direct axis swashplate plunger pump is divided into two types: pressure oil supply type and self-priming type. The pressure oil supply type hydraulic pump mostly selects the oil tank with air pressure, and the hydraulic pump itself is equipped with a make-up pump to supply pressure oil to the oil inlet of the hydraulic pump. The self-priming hydraulic pump has a strong talent of self-priming, and there is no external oil supply. The hydraulic oil tank supplied by air pressure can operate the machine only when the hydraulic oil tank reaches the application air pressure after starting the machine every time. If the air pressure of the hydraulic oil tank is short, it will act as a machine, which will pull off the hydraulic pump and the sliding whip, and will cause abnormal wear of the return plate and the pressing plate in the pump. Select the plunger pump supplied by the make-up oil pump. After use, the operator needs to check the plunger pump 1-2 times a day to see whether the working dynamic of the hydraulic pump is normal. If it is found that the speed of the hydraulic cylinder drops or the vehicle is blocked, it is necessary to check whether the empty position of the internal gear pump is too large.

BusinessRules For Operation Of Roots Vane Vacuum Pump Unit by hhm1020(op): 10:37am On Aug 08, 2019
Rules for operation of general wet Roots vane vacuum pump units

General Roots vacuum unit operation in accordance with the relevant rules of dry Roots vacuum pump, but also need to pay attention to the following related matters;

1) Pump should be run empty before use to check whether the rotating parts are flexible, whether there is blocking phenomenon, whether the rotation direction is correct, whether there are abnormal noise and vibration in the pump. Before starting, pull the pulley by hand, check whether there is any obstacle, and inject proper amount of clean water, and inject the prescribed grease into the gear box. Connect to the power supply, click a few times first, observe whether the situation is normal, and then measure the current after starting. If it is found that there is no indication on the vacuum gauge or the reading is very small, it is necessary to check whether the valves on the gas-water separator are sealed, whether the valves on the suction pipeline and the closure doors on the suction tank are sealed, and whether the flanges, joints and pump shells on the pipeline are leaking, and to eliminate them after finding out the causes.

2) Before starting the pump, the valve on the suction pipe should be opened and other valves should be closed.

3) The shutdown operation should follow the following procedures.

Press stop press and turn off the power supply;

(2) Vacuum sealed cooling water and re-tighten the water plug (temporary parking can not be emptied);

(3) Temporary shutdown, although not water, should be put into the air to destroy the vacuum condition in the pump, so that the next start-up is easy.

4) Notes for operation and use.

(1) Pumping should be started before the vacuum equipment is pumped;

(2) Pump shutdown should be after braking the vacuum pumped equipment;

(3) Water injection and exhaust should be done before starting the pump.

(4) Controlling the vacuum degree of the pump can adjust the valve on the inlet pipeline and adjust the closure door of the outlet of each suction tank when changing the vacuum degree of each suction tank.

_When the vacuum is too high, appropriate amount of air can be put into the water injection valve on the inlet pipe.

_When choosing a pump, attention should be paid to the balance between the external load and the pump's capacity. If the pumping speed of the vacuum equipment is greater than that of the pump, the pump's capacity is insufficient, and the vacuum degree is greatly reduced, which can not meet the proper use requirements. At this time, several pumps can be considered in parallel.

When the load of the external equipment is not much larger than the capacity of the pump, the speed of the pump can be increased, the speed of the pump can be increased, the pumping speed should be increased, and the power should also be increased, but the increase of the speed should not exceed 25% of the rated speed.

_After using for a period of time, the side plate of the stabilizer box and the lower drain bolt should be removed, the rotor rotated, the dirt washed out with water, and then assembled for reuse.

Basic Principle of Roots Vacuum Pump with Direct Exhaust Atmosphere

Roots pump uses internal cooling method, heat is directly taken away by circulating cooling air from the heat source, that is, the exhausted gas, when it is compressed or discharged, it is cooled by cooling air, so this kind of pump can be used where the standard pump can not work.

The pump chamber can be cooled by itself, because the impeller and the working chamber have a special working part. When this special part is working, a part of the working chamber is closed, blocking the inlet and outlet. Through the special ventilation port, the cooling gas flows out from the pressure side, or enters the working chamber again, and then from the outlet side by the pressurized cooling. But when the gas is filled, the gas is circulated.

Roots pump with internal cooling in gas cycle is controlled by a special impeller head without additional control elements. Therefore, the structure of this kind of Roots pump with internal cooling is simple and clean as that of ordinary Roots pump. It connects the cooler with the exhaust port, and the cooler is installed outside the pump housing for easy maintenance and replacement.

If the cooler is designed correctly and the pipe size for conveying cooling gas is large enough, the cooling effect is very good, so that Roots pump can work under various pressure differential conditions.

Pump heating depends not only on speed and circulating cooling dose, but also on pressure difference, which is proportional to speed. In addition, the clearance between the blade and the pump housing should be kept at a minimum. This is conducive to the improvement of volumetric efficiency in order to obtain a higher vacuum.

Gas cycle cooling Roots pumps are most suitable for those processes that discharge and compress gases or vapors. These exhausted or compressed gases should not be in contact with oil or harmful liquids before entering the pumps, such as nitrogen cycle in cryostat. If the pressure difference between intake and exhaust is very large and the required limit vacuum is very high, three Roots pumps can be considered in series. In addition, there are also water cooling or multi-stage pumps.

BusinessTroubleshooting Method Of Rotary Vacuum Pump by hhm1020(op): 9:46am On Jul 25, 2019
Summary:

If the rotary vane vacuum pump is not properly operated, it will often fail. For example, the vacuum degree of the rotary vane vacuum pump decreases, oil injection, smoke, oil leakage at the oil seal, noise and so on, and the phenomenon of oil emulsification of the vacuum pump in the pump. In case of such a situation, first of all, do not panic, and after the shutdown, according to the fault one by one elimination. Here are some troubleshooting methods.

Smoke and fuel injection of rotary vane vacuum pump: Smoke or fuel injection from exhaust port of rotary vane vacuum pump in operation.

1. Smoking, if the pump has just started to operate smoking phenomenon, belongs to normal, if smoking for a long time is abnormal. Solution: Smoke shows that the pump intake, including pipelines, valves, containers are repaired. After leak detection, the smoking will end. Vortex Flowmeter

2. Fuel injection indicates that there are a lot of leaks outside the intake, even the intake exposes the atmosphere. Solution: Seal the intake port of the pump to make the pump run. If there is no injection, there is a leak point. The exhaust valve piece is damaged, check whether the exhaust valve piece is damaged, and replace the damaged exhaust valve piece.

2. Rotary vane vacuum pump noise: here refers to the noise of the pump.

1. Knock on the cylinder, the pump makes irregular sound when it is running, like the sound of metal knocking on metal. This is the sound of the rotary blade hitting the pump body. This situation is mainly caused by the spring breakage or the failure of contraction or ejection between the paired rotating blades. Solution: Open the pump to check whether the blade spring is damaged. Replaced spring.

2. The noise of the exhaust valve piece is mainly caused by the damage of the exhaust valve piece of the pump. Solution: Replace the exhaust valve disc. 3. Decrease of vacuum degree of rotary vane vacuum pump: It means that the vacuum degree of rotary vane vacuum pump measured at present is lower than that of factory index or used before. There are many reasons for low vacuum. Here are several main situations.

1. The brand of rotary vane vacuum pump oil added this time is different from the original one. Different grades of vacuum pump oil have different results because of different saturated vapor pressures in different grades of oil. Solution: Replace the correct new vacuum pump oil according to the product model specifications.

2. In addition, it is also due to the low vacuum caused by vacuum pump oil, that is, the emulsification and discoloration of vacuum pump oil, or too dirty. Solution: Clean all the vacuum pump oil in the pump, replace the same type of vacuum pump oil, and solve the problem that water vapor and impurities in the pumped gas do not enter the pump.

3. The temperature of the exhausted gas may be too high. Solution: Reduce the temperature of the exhausted gas, or add a corresponding heat exchanger.

4. The oil passage in the pump is blocked or not smooth, and there is not a certain amount of oil in the pump chamber. Solution: Check whether the oil pipeline is smooth, and add the same type of vacuum pump oil.

5. Increase the clearance of coordination. This is a long-term exhausted gas containing dust and so on, resulting in wear between the rotor and stator gap increases. Solution: Check whether the gap is too large and replace new parts.

BusinessMaintenance Of Ventilation Of Water Ring Vacuum Pump by hhm1020(op): 10:39am On Jul 23, 2019
If you want to use this product better, you must have a comprehensive understanding of it. Water ring vacuum pumps are the same. Now let's understand the whole process of natural ventilation of sewage ring vacuum pumps.

Water ring vacuum pump discharges gas outward, which reduces the standard air pressure in the room and makes the indoor air quality thinner. It generates an air pressure zone. The gas is compensated for the standard air pressure difference and injected into the room. In the practical application of the workshop, it is centralized installed on one side of the industrial workshop, and the air inlet is located on the other side of the industrial workshop. During the whole process, the aluminium alloy doors and windows close to the water ring vacuum pump are closed, forcing the gas to be compensated by the aluminium alloy doors and windows on the side of the air intake into the production workshop, and the gas is queued up and disciplined and injected into the production workshop from the air intake through the production workshop by the aluminium alloy doors and windows on the side of the air intake. It is discharged into the production workshop.

Fully ventilated and highly efficient, the ventilation rate can reach as high as hg98%. According to the design of main building projects and the ventilation rate and wind power of the necessary design schemes, all high temperature, harmful substances, smoke and smoke can be quickly discharged into the production workshop, and all problems of poor natural ventilation can be completely eliminated at one time, from the opening of the station within a few seconds. Yes.

The whole process of natural ventilation of water-ring vacuum pump is introduced. Excellent natural ventilation determines the characteristics and operation of the machine and equipment. Therefore, we should pay more attention to the maintenance of the natural ventilation level in the future application and maintenance, and this kind of machine and equipment is widely used at this stage. It has a very good future and is a reliable commodity for everyone.

BusinessWhat Are The Power Supply Modes Of Screw Vacuum Pump by hhm1020(op): 9:16am On Jul 18, 2019
Screw vacuum pump is widely used in life for its advantages of wide pumping speed range, simple and compact structure, no friction of the components of the pump chamber, long life, low energy consumption and no oil pollution. Moreover, electricity is the power source of the screw vacuum pump, and the way of obtaining electricity can also be different. The influence of different power supply modes on the equipment is different. It's also different.

1. Screw vacuum pump because the extraction medium is "water or liquid", is characterized by a larger proportion, and micro vacuum pump, micro air pump and other working medium is "gas", a lighter proportion. Therefore, the working current of screw vacuum pump is generally larger than that of the latter, about 1 to 10 amperes, while the latter's working current is generally not large, ranging from several hundred milliamperes to several amperes.

2. Batteries.

Battery is the general term of battery. Because the principle is different from the dry battery, it can provide larger current and power, so it is widely used in electric vehicles, cars and other mobile vehicles, agricultural spraying spray, field sampling and other occasions where there is no power supply, and it can also be used to supply the screw vacuum pump.

2. Commonly used dry batteries (such as 1.5V No. 1 battery) are suitable for power supply of screw vacuum pump because of their large internal resistance, small current provided by themselves, and a large part of the voltage is consumed on the internal resistance.

It is important to choose the proper power supply for screw vacuum pump. The voltage, resistance and current of different power supply modes are also different. Screw vacuum pump using appropriate power supply will also provide the corresponding efficiency.

BusinessCauses Of Cavitation In Screw Vacuum Pump by hhm1020(op): 9:41am On Jul 10, 2019
Cavitation often occurs in the use of screw vacuum pump, which is a high noise and destructive phenomenon often occurring in hydraulic machinery. The occurrence of this phenomenon will not only break the vacuum pump, but also cause impeller perforation to cause serious damage to the equipment.

The mechanism of cavitation is due to the action of liquid dynamics. When the local pressure of moving liquid drops to the vaporization pressure at this temperature, the liquid begins to vaporize and forms bubbles. The bubbles are filled with liquid vapor and a small amount of gas dissolved in the liquid. When the bubbles reach the region where the static pressure exceeds the critical pressure along with the moving liquid, the steam in the bubbles suddenly condenses and the bubbles burst. Because the pressure in the bubbles is always below or near the critical value, and the pressure of the outside liquid is relatively large, when the bubbles burst, the surrounding liquid rushes to the center of the bubbles at a very high speed to form a high-frequency water hammer effect, which produces a high local stress and temperature rise, and produces noise and vibration. Repeated occurrence and collapse of such bubbles will destroy the surface of parts in this area. In addition, chemical and electrochemical corrosion of liquid and parts materials will cause cavitation damage with spongy or honeycomb characteristics.

In addition, even above the critical pressure, the screw vacuum pump may also produce cavitation phenomenon. Because when the pressure decreases, the air and other gases dissolved in the liquid will be analyzed, and at the same time, the vapor of the liquid will be brought out to form bubbles filled with liquid vapor and gas. These bubbles are particularly easy to grow and grow on the surface of moving parts, which are taken away by the liquid and will suddenly condense and burst at high pressure. Cavitation is caused by extinction. However, the critical pressure for cavitation varies with the properties of liquids, temperatures and dissolved gases.

Cavitation phenomenon of screw vacuum pump is mainly produced in the operation of the equipment. More attention must be paid to this problem when finding the reason, so as to ensure the normal operation of the equipment and avoid affecting your normal use.

BusinessHow To Embody The Advantages Of Dry Vacuum Pump? by hhm1020(op): 9:47am On Jul 08, 2019
With the whole level of dry vacuum pump, we should accelerate the ability of product production, enhance the performance of its strength in all aspects, increase investment in product development, actively learn advanced skills in all aspects, enhance the ability of self-development, and then show the function of dry pump.

Dry vacuum pump is the trend of future career development. Although it is not used much now, besides the high price, there are also users who do not know the dry vacuum pump well and can not see the future economic benefits brought to enterprises. Here, how to optimize the selection of dry vacuum pump is emphasized.

For these different types of dry vacuum pumps, we all hope to reduce their physical scale. But this is opposite to the pumping rate of the vacuum pump, because the pumping rate of the vacuum pump is proportional to the volume of the vacuum pump, small physical scale means small volume. Of course, there is also an important factor affecting the pumping rate of vacuum pumps, that is, speed.

In order to match the pumping rate of small-scale vacuum pump with that of large-scale vacuum pump, it is necessary to improve its speed. There are two ways to change the speed of the vacuum pump. One is to change the frequency of the power supply, that is, to choose the frequency converter and to change the transmission ratio of the gearbox. In the meantime, the advantage of using frequency converter is that it can provide a closed-loop control, but it simply causes the loss of torque under heavy load.

Forum GamesTypical Uses Of Stainless Steel by hhm1020(op): 6:51am On Jun 28, 2016
Most of the requirements for long-term use of the building original appearance. In determining to choose the type of stainless steel, the main consideration is the aesthetic standards required by the system to be used to clean corrosion and atmospheric location. However, a growing number of other applications just to seek completeness or permeable structure. For example, industrial building roof and side walls. In these applications, the owner of the construction costs may be more important than the aesthetic, the surface is not very clean may be.3mm stainless steel sheete

However, in rural and urban areas in order to maintain its appearance in the outdoors, they need frequent cleaning. In heavily polluted industrial areas and coastal areas, the surface will be very dirty, and even rust. But to get the aesthetic effect of the outdoor environment, it requires the use of nickel-containing stainless steel. Therefore, the 304 stainless steel is widely used in curtain wall, side walls, roofs and other construction purposes, but in severe erosion industrial or marine atmosphere, preferably 316 stainless steel.stainless steel strips suppliers

Because "duplex" 2205 Yiba good atmospheric corrosion resistance and high tensile strength and proof strength blend, so the European guidelines also include this steel. Product shape, in fact, is the all-stainless steel standard metal manufacturing of shape and size, but there are many special shapes. The most commonly used product is made of sheet and strip, plate is also used to produce special products, for example, the production of hot-rolled structural steel and extruded structural sections.316 Stainless Steel Bolts Mechanical Properties
