ZWself-priming sewage pump product instruction
ZW series self-priming sewage pump, also known as solid-liquidpump or pump impurities. This series of pump hydraulic design is unique, the impeller is contracting in the leaf chamber alone,connected with the impeller chamber is pressurized water chamber,when the impeller rotates, the liquid in the pump axial eddy currenteffect of strong, making imports caused by vacuum, exports have alift. So the impurities can be discharged from the water pressure chamber, so that the channel is completely unimpeded, the effect of sewage is other self suction there is nothing comparable to this. With the installation, use, convenient movement, stable performance,repair rate is extremely low, favored by the majority of users.
ZWself-priming sewage pump scope
ZW series of non clogging Self-priming sewage pump is widely usedin municipal sewage works, light industry, paper making, textile, food,chemical, electric power, petroleum, mining and pond aquacultureindustry. It is the impurity pump domestic pumping solid particles,fibers, paste and mixed suspension medium ideal.
ZWself-priming sewage pump structure and working principle
ZW series self-priming sewage pump mainly by the pump body,impeller, back cover, mechanical seal, pump shaft, bearing seat, inlet valve, gas-liquid separation tube, water valve, exhaust pipe burst,etc..
The working principle of pump: the pump body is provided with a liquid storing cavity, and through the circular hole at the top of thebackflow hole and below and the pump cavity, composed of a pump with outer recirculation and system. The pump stops working. Pump cavity has a certain volume of liquid storage. When the pump starts", pump the liquid in the impeller under the action of liquid separationgrid, back to the working cavity tube by gas liquid, gas is discharged out of the pump, the pump within a certain vacuum degree, achieveself absorption effect.
ZWself-priming sewage pump main parameter
Self suction height：4.5-6.0m。
