Pump encyclopedia: Pneumatic lift pump structure function principle analysis

Pneumatic lifting pump is equivalent to a low-pressure fluidized storage tank, the upper part of the pump is a pump body, and the lower part is a gasification chamber with a porous air-permeable plate in the middle. The primary air outlet is equipped with a nozzle and is aligned with the conveying pipe: an expansion chamber is arranged at the outlet of the upper part of the auxiliary material pipe, and the secondary air is connected with the gasification chamber, through which the ash blows to form a paralysis state. The amount of air by the ball valve to adjust the air supply by Roots blower. Air chute - pneumatic lift pump system is characterized by simple structure, light weight, no moving parts, wear small, easy and reliable operation and maintenance, for lifting height greater than 30m more economical. And can feed, discharge, continuous delivery. The disadvantage is to enhance the pump body, power consumption is larger.
