Pump industry suppliers to tell you: the difference between the vertical self-priming pump and submerged pump

the classification of self-priming pump

water ring wheel type self-priming pump water ring round and pump impeller combination in a casing, with the aid of water ring round the gas discharge, achieve self-priming. When the pump work normally, can through the valve block water ring and pump impeller channel, and put off water ring round within the liquid. Jsog self-priming pump, made from a mix of centrifugal pump and jet pump, rely on the spray device, on the nozzle vacuum suction. According to realize the structure and working characteristics of self-priming function can be divided into inside outside sliding type, sliding type, water ring wheel and other type, transmission way has a direct drive and belt drive, imported from 25 to 200 mm in diameter.

the difference between the vertical self-priming pump and liquid pump under

1, the overall self-priming pump for vertical structure, compared with the same parameters of submerged pump, greatly reduce the weight, and covers an area of less. Because of the axis vertical installation, shaft seal is not easy to leak.

2, self-priming pump was cancelled long axis, at the same time also cancelled the problem of bearing, greatly extend the maintenance period, at the same time reduce the vibration. Empty pump operation can still maintain a long time, to help find and take measures to prevent the damage to the motor, reduce the loss caused by wrong operation, good safety.

3, possible damage and need repair parts on the ground, giving the maintenance has brought great convenience, pump inlet is just a hollow tube, no need of bottom valve. Such as inlet were choked up with rubbish, sort, hollow tube can be pulled out while submerged pump out the whole pump is needed to clean up. Submerged pump must be installed in the liquid directly above, available resistance cannot reach the liquid suction vacuum hose straight pipe, the maneuverability is strong.

4, submerged pump needs to determine when buy smoke liquid depth, if the liquid depth and pump shaft length discrepancy, need to change another pump, and as long as vertical self-priming pump equipped with different length of hollow tube, can pumping different depth without changing itself.
