Overview

The self-priming height of a self-priming pump is related to factors such as the sealing gap in front of the impeller, the pump speed, and the liquid level in the separation chamber. The smaller the sealing gap in front of the impeller, the greater the self-priming height, generally taken as 0.3~0.5 millimeters. FMZ type horizontal self-priming pump manufacturer

After the water discharge is normal, tighten the filling hole cover and slowly adjust the valve on the outlet pipe to the desired working condition. It usually takes 2-10 minutes to start and discharge water.
C 、 The temperature rise of the pump bearing and motor should be checked regularly, and the temperature rise of the bearing should not exceed 75 degrees.
D 、 Pay attention to the absence of noise during pump operation. If any abnormal situation occurs, stop the pump immediately for inspection.
2. Parking
A 、 Slowly close the outlet pipeline valve and various instruments.
B 、 Cut off the power supply.
