进口高效多级泵美国阿卡迪亚品牌

进口高效多级泵Product Description:

It mainly includes the pump body, pump shaft, first stage impellers, multiple intermediate impellers and final stage impellers. The front and rear parts of the side of the pump body are respectively provided with pump inlet and pump outlet. The pump shaft is horizontally arranged in the pump body in the front and rear directions, and the first stage impellers and final stage impellers are respectively sleeved at the front and rear ends of the pump shaft, so as to reduce the leakage and improve the efficiency of the multi-stage centrifugal pump. At the same time, Part of the leaked media through the spiral groove re enters the inside of the balance drum with spiral groove, which reduces the swirl generated by the leaked media at the gap B, reduces the vibration of parts, and prolongs the service life of the centrifugal pump.

进口高效多级泵characteristic:

Multistage pumps can be used in many industrial sectors such as petroleum, chemical industry, machinery, mining, light industry, medicine and food. In order to meet the process needs and improve the head of the centrifugal pump, the multi-stage pump is equipped with two or more impellers on the pump shaft. At this time, the total head of the pump is the sum of the heads generated by multiple impellers. At the suction port of the single suction centrifugal impeller, due to the asymmetry of the front and rear cover plates of the impeller, an axial force pointing to the suction port will be generated during the operation of the pump. The axial force is very large in the multi-stage pump, so balancing the axial force of the multi-stage pump is an extremely important design step.

进口高效多级泵Principle:

It mainly includes a pump body, a pump shaft, a first stage impeller, a plurality of intermediate impellers and a last stage impeller. The front and rear parts of the side of the pump body are respectively provided with a pump inlet and a pump outlet. The pump shaft is horizontally movable in the pump body in the front and rear directions, and the first stage impeller and the last stage impeller are respectively sleeved at the front and rear ends of the pump shaft. The intermediate impeller is equally spaced and fixedly sleeved on the pump shaft, and the intermediate impeller is located between the first stage impeller and the last stage impeller; The first stage impeller and the last stage impeller are located between the pump inlet and the pump outlet; The front and rear ends of the pump shaft are sleeved with suspension components. The bearing inner rings in the suspension components are fixedly sleeved with the pump shaft, and the suspension components are respectively fixed at the front and rear ends of the pump body with bolts. The suspension components play a role in rotating, supporting and sealing the pump shaft; The front side of the first stage impeller is provided with a balance drum, the balance drum is fixedly sleeved on the pump shaft, and the inner wall of the balance drum is processed with a spiral groove; The outer spacer sleeve of the balance drum is provided with a balance drum sleeve, which is fixedly connected to the pump body by bolts, and a balance chamber is arranged between the front surface of the balance drum sleeve and the suspension component, and the gap between the balance drum and the balance drum sleeve is connected with the balance chamber.
