Problem | Reason | Solutions |
Does not rotary | (1) Power system broke, the motor does not rotate (2) Exogenous impurity into the air pump (3) Water seeps into air pump bearings or bearings are rusted or bearing oil-free and then bearings are stuck (4) Bearing is damaged or bearing is oblique and then impeller and pump body are stuck. | (1) Check the power supply and motor to remove the fault ; (2) Decomposition air pump to eliminate exogenous impurity; (3) Clean or replace bearings and add grease ; (4) Disassemble and repair and replace the bearing; |
The motor is hot or burned | (1) Three-phase power is unbalanced or lack phase (2) The power plug is loose or the power plug is poor contact (3) The output tube is blocked, so the output pressure is extra high (it is higher than 80% of the highest pressure) | (1) Check the power voltage and power wiring; (2) Check the power wiring and replace the plug socket; (3) Check whether the diameter of the output pipe is reasonable, check whether there is foreign body clogging or the valve is closed |
Insufficient pressure-flow output, high air pump temperature, and excessive motor current. | (1) Air inlet filter is blocked by dust or foreign matter. (2)The foreign matter is blocked in the inlet of the pipe or the valve is closed. (3)There is a leak place in the outlet of the pipe. (4) The pressure relief valve is set too small (5) Wrong direction of air pump rotation | (1) Clean the filter element. (2) Clean and check the inlet of the pipe and open the valve (3) Check for leak places and take measures to plug them (4) Adjust the pressure relief valve (5) Change the three-phase connection of the power supply to make the pump rotate in the correct direction |
Sound abnormal and noisy | (1) Bearing wear, the impeller of the air blower is stuck (2) The foreign matter is in the air pump (3) There are loose parts in the air pump (4) The air pump is not properly placed on the land, it shakes during operation. The hard connection between the pump and the pipe, the angle of the pipe and the pump is not adjusted very well. | (1) Replace bearing or impeller. (2) Decompose and repair to remove foreign matter. (3) Check for looseness and tighten. (4) The Level place or fixed it in a more reliable place. (5) Using a hose to connect the air blower and hard pipe. |
