进口浆料离心泵美国阿卡迪亚品牌


进口浆料离心泵Product description:

 

The centrifugal pump comprises a pump body, an impeller, a pump cover, an impeller nut, a bearing box, a bearing body and a pump shaft; The front end of the pump body is connected with a pump cover, the rear end of the pump cover is connected with a bearing box, the pump body and the pump cover are equipped with impellers, the impellers are equipped with S-shaped rotary blades, the impeller fixing sleeve is arranged at the left end of the pump shaft, the right end of the pump shaft extends through the bearing box, and the pump shaft and the bearing body are fixedly sleeved through the bearing. The S-type rotary blade and back blade are set to reduce the linear velocity difference of the outer circle of the impeller, so as to improve the passing rate of the medium

 

进口浆料离心泵characteristic:

 

PVC slurry chemical centrifugal pumps are widely used in chlor alkali, plastic, polyvinyl chloride, polypropylene, chemical fiber and other industries, and their working environment is worse than that of centrifugal pumps in other industries. The conveying medium is characterized by high temperature, high viscosity, suspended particles and solid content with a diameter greater than 10mm, and the medium can crystallize and solidify into sheet solids in a short time when it is not fully reacted, and tangles accumulate between two blades, resulting in reduced pump flow, head, low efficiency, blocked flow passage, etc. At the same time, as the liquid level of polymerization kettle decreases, the pressure gradually decreases from 0.8Mpa to 0.02Mpa, and the pressure at the pump inlet is unstable, leading to obvious pump vibration and evacuation.

 

进口浆料离心泵Principle:

 

The back blade is set at the back of the impeller. The solid concentration gradient is common, which is caused by various forces acting on PVC, including gravity, fluid resistance and centrifugal force. As the slurry flows into the impeller, it needs to turn through a flow angle of 90 degrees to be led out of the pump. Through inertial force and Coriolis force (applied by the blade), the PVC slurry has the highest concentration at the root of the rear cover plate of the impeller, that is, at the side edge where the blade contacts the rear cover plate. By setting the back blade on the rear cover plate of the impeller, the driving pressure of the slurry in the gap is reduced, and a centrifugal force field is formed on the blade and the rear cover plate to discharge particles. This setting can reduce the driving pressure of PVC in the gap and reduce the driving force of the return flow, so that the PVC concentration in the cavity remains uniform and the rear flow speed is reduced to reduce the wear of the blade root.
