1. Check the pump and motor before installation, the parts shall be intact, and the pump shall have no sundries.
2. Put the pump in the horizontal position to connect the inlet, outlet pipe and the power supply, and finally use the hand disc to move the coupling, check whether there is any friction, and the rotation is easy and uniform, and the installation is finished.
3. Worse than metal fluoride plastic pump steel degree, so the line weight cannot be directly on the pump body, inlet and outlet pipe should be plus stent, under high lift pump in exports should also install the check valve, to prevent the water hammer damage of sudden stop.
4. All joints must be kept sealed to prevent leakage and fluid influence on the performance of the pump.
5. If the vibration or abnormal sound is found during operation, the reason for the stop check should be stopped immediately.
1.Fill the pump with sufficient liquid (primer)
2.The oil level of the oil chamber is within the specified range.
3.Check the running direction of the motor and adjust the rotation mark of the pump.
4.Close the outlet valve and pressure gauge cock.
5.Start the motor, open the pressure gauge cock and slowly open the exit valve. When the pressure gauge pointer indicates the desired position, stop the adjustment of the outlet valve size.
6.When it is important to stop, first turn off the outlet valve and then cut off the power supply.

The fault |
why |
The solution |
|
unliquid |
1. There is air in the suction pipe and the inlet is blocked. 2. The height is too high. 3. The lift is required to be greater than the pump lift. 4. The discharge pipe is too thin, and the pipe loss is too large. 5. reverse |
1. Clean the pipeline and clean the air. 2. Reduce pump mounting height. 3. Replace the pump with large head. 4. Large output pipes, such as diameter and pump port. 5. Change direction |
|
Lack of traffic |
1. Impeller damage. 2. Damage to seals. 3. Insufficient revolution 4. The inlet pipe is too thin. 5. Excessive bending of the outlet pipe and excessive resistance. |
1. Replace the new impeller. 2. Replace the seals. 3. Increase the number of revolutions 4. Reinstall pipes according to regulations. 5. Rearrange the pipeline properly. |
|
Lift is insufficient |
1. Excessive viscosity of gas or medium in the conveying medium. 2. Impeller and blade damage. 3. Insufficient revolution |
1. Reduce medium viscosity or increase suction pressure. 2. Replace the impeller. 3. Increase the number of revolutions |
|
Leakage of shaft end |
1. The mechanical seal ring is too loose. 2. Too large gap between the transition dimension of shaft end card ring. |
1. Screw the two inner hexagon screws. 2. Remove the pump, the shaft, the card baffle the F4 raw material belt film several ring tight fit, tighten the bolt. |
|
Tight seal leakage |
1. Improper selection of material for sealing elements. 2. Severe abrasion of friction pair. 3. The static and static ring is not uniform. 4. The friction pair is too large and the ring is broken. |
1. Describe the media situation to the pump string, with appropriate stator ring. 2. Replace the worn parts and adjust the spring pressure to reduce wear. 3. The sealing assembly is released, and the ring bolt is reset to the correct position. 4. The whole pump is disassembled, and the static ring is required to install the seal assembly and the axial perpendicularity error.0.10 |
|
The pump has a noise or pump vibration. |
1. The pump shaft is different from the motor shaft. 2. The flow exceeds the scope of use to produce cavitation. 3. Cavitation of the pump. 4. Wear of motor and bearing. |
1. Calibration pump shaft center. 2. Select the appropriate pump type and operate according to the range of pump. 3. Lower the temperature of the medium or increase the suction pressure. 4. Clean or replace the bearing. |
