First, the installation requirements of the submerged pump 1, submerged pump pump must be installed vertically on the liquid pool or sink above the fixed bracket.
2. The suction port of the pump under the liquid pump should be greater than 200 at the bottom of the tank.
3, the outlet pipe of the pump under the liquid pump must be provided with a separate bracket, do not allow its weight directly on the pump body.
Second, the submerged pump disassembly sequence 1, the submerged pump closes the gate valve in the pressure out of the pipeline, remove the spout pipe on the part of the flange of the connecting bolt or connecting the pipe. Remove a section of tubing, the length of which will not interfere with the lifting of the pump.
2. Under the liquid pump, loosen the bolts connecting the motor frame and the motor and lift the motor.
3. Remove the bolts of the pump body and bracket and rotate the impeller.
4. Remove the middle bracket and pull off the coupling.
5, remove the bearing body upper and lower bearing caps, you can check the bearing condition.
Third, the liquid pump start, stop and run requirements 1, before the liquid pump motor is not installed, should turn on the power supply to check the direction of rotation, must be consistent with the direction of rotation of the pump.
2. The submerged pump is equipped with a motor and the coupling is rotated to check whether the pump shaft is concentric with the motor and whether the rotation is uneven or not, and then the operation is normal.
3. The submerged pump closes the outlet line valve and pressure gauge.
4. Start the electric motor under the liquid pump and open the outlet valve to the required position with the pressure gauge.
5. When the submerged pump is stopped normally, the outlet valve should be closed first, then the motor should be stopped and the pressure gauge should be closed.
6. The bearing compartment of the submerged pump should ensure sufficient grease, and the temperature rise of the bearing must not exceed 70°C.
