First, the installation of submerged pump requirements 1, submerged pump pump must be installed vertically in the liquid pool or sink above the fixed bracket. 2, liquid pump suction inlet from the bottom of the pool should be greater than 200 mm. 3, liquid pump outlet pipe must be set up another bracket, does not allow its weight directly on the pump body. Second, the sub-pump disassembly sequence 1, liquid pump off the pressure out of the pipeline valve, remove the discharge pipe part of the flange on the bolt connection or connection take over. Remove a pipeline, its length does not hinder the lifting of the pump shall prevail. 2, liquid pump to loosen the motor frame and the motor bolts, hanging to the motor. 3, remove the pump body and bracket bolts, screw off the impeller. 4, Remove the middle bracket, pull down the coupling. 5, remove the bearing body bearing up and down, you can check the bearing condition. Third, the liquid pump start, stop and run requirements 1, liquid pump motor is not installed, it should be connected to check the power rotation direction, the pump must be consistent with the direction of rotation. 2, liquid pump installed on the motor, disk drive coupling, check the pump shaft and motor concentric, rotation is uneven, normal and then run. 3, liquid pump off the export pipeline valves and pressure gauges. 4, liquid pump start the motor, pressure gauge to open the outlet valve to the desired position. 5, liquid pump normal parking, you should first close the outlet valve, and then stop the motor, turn off the pressure gauge. 6, liquid pump bearing room should ensure adequate oil, bearing temperature rise shall not exceed 70 ℃.
