Product structure:
Pneumatic desilting sewage pump is composed of main part ,control system vacuum pump and other components.
Main part : pump body, feed pipe, discharge pipe, its function is absorb and discharge.
1. Control system: control system take advantage of pneumatic operated alternative valve, shuttle valve, ball valve and time logic alternative valve
to realize actuator’s control and switch, in order to achieve alternately absorb and discharge.
2. Vacuum suction components: it is designed according to the principle venturi effect ,including inlet air ,outlet and vacuum port. When the air pressure of the air inlet is higher than a certain value, nozzle jet supersonic ,due to gas viscosity, High-speed jet volume absorb negative pressure cavity gas, in order to form high vacuum . The performance of the vacuum generator have relation with the minimum diameter of nozzle, shrinkage and diffusion tube shape, size and its relative position, size of the air pressure and many other factors. The vacuum suction are interlinked with pump body through pump body. Control system alternative switch control cylinder can finish absorb and discharge process.
