For self-priming Pressure Controller For Borehole Pumps, each self-priming pump should be equipped with a separate suction pipe, and the length and fittings of the suction pipe of the self-priming pump should be minimized

The slurry is sprayed axially into the chamber, and the vortex separates the large-size material from the rest of the slurry and liquid; the remaining slurry and liquid are removed

The moving and static parts are rubbed against each other.　　 (5) The prime mover itself vibrates, and the coupling can be disconnected for operation inspection.　　 The second reason is the liquid aspect, which may be:

Pumping is not recommended for transporting particles For the liquid, because the service life of the pump will be reduced according to the number, size,

There are usually five materials: plastic, aluminum alloy, cast iron, stainless steel, and Teflon.. The transmission part is a driving mechanism that drives the diaphragm to agitate back and forth

The screw pump needs to be overloaded during oil production. The overload of the screw pump will cause the oil well to break the rod, break the belt, damage the gears and bearings in the reduction box, and even burn out the motor.
