Main Parts Of Centrifugal Pump by hhm1020: 8:01am On Aug 16, 2022 |
Centrifugal pump is composed of many parts. According to the working state of each part during operation, it can be roughly divided into three categories Type: rotating part, fixed part J4: and handover part. Taking the single-stage single suction horizontal centrifugal pump as an example, as shown in Fig. 2.4, the function, composition, structure and material of each part are introduced. 1 impeller (also known as working wheel) The drum is the main part of the water pump, and even the core part of the water pump. The centrifugal system relies on the high-speed rotation of the impeller Water is used to realize energy conversion. The N1 wheel rubber of the centrifugal pump is composed of two circular cover plates. There is a gap between the cover plates. 1: the bent blade will be two in front and back The two cover plates are connected together, and the space groove surrounded by the two adjacent blades and the front and rear cover plates is generally called the flow of water. (2) accumulated glaze The beam rib is used to rotate the pump impeller. It receives power from the prime mover (motor) and drives the impeller to rotate. Thus, the pump The shaft shall have sufficient torsional strength and rigidity, and its deflection shall not exceed the allowable value; The working speed cannot be close to resonance The critical speed of the phenomenon. Common materials of pump shaft are carbon steel and stainless steel. 3. Key The impeller and the pump rail are connected by keys. The chain is commonly known as the connecting piece of rotating parts. 3 in Fig. 2.4 is a centrifugal pump The usually used flat key can only transmit torque and cannot fix the axial position of the impeller. In large and medium-sized fruits, the leaf The axial position of the wheel is usually located by the shaft sleeve and the nut of the shaft sleeve.
