Product structure:
Pneumatic esilting sewage pump is composed of main part ,control system vacuum pump and other components.
Mainpart : 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.
