Product information

The structure and working principle of pneumatic sewerage pump accessories.

The main components of QYF series are main parts, control system and vacuum pumping components.

1. Main body: composed of pump body, feed pipe and discharge pipe, the work of which is to absorb material and discharge.

2, control system, control system mainly using pneumatic directional Control Valve, shuttle valve, ball valve, and time is the combination of logical reversing valve body, realizes the control of the actuator and switch, reaches the unit work orderly transformation of absorb and layout.Shaanxi mining pneumatic sewage pump manufacturer | dredging pump picture.

3. Vacuum pumping assembly: it is designed according to the principle of venturi effect, including air supply, exhaust and vacuum mouth.When the supply of gas supply pressure is higher than a certain value, the injection of supersonic jet nozzle, due to the viscosity of the gas, high-speed jet gas entrainment go negative pressure cavity, this cavity to form high vacuum degree.The performance of the vacuum generator is related to the minimum diameter of the nozzle, the shape of the contraction and diffusion tube, the diameter and relative position of the nozzle, and the pressure of the gas source.The vacuum pumping unit is connected with the suction nozzle through the pump body, and the feeding and discharging process can be completed when the control system circulates to control the cylinder work.
