Water pump common problems
If you follow the instructions in the following table, you can not exclude a certain fault, please:
turn off the machine2
turn off the power plug
Call customer service phone +86-593-6695002
Fault | Reason | Measures |
Motor can not start | Motor voltage is too low:a.Low power supply voltage; | a.Will be transferred to the rated voltage rang. b.Power cord with larger cross section. c.Move closer to the power line position. |
Single phase power supply(3-phase):a.Poor contact of power switch;b.Fuse fuse c.Power cord loose;d.Cable fault phase | a.Repair switch contact or replace switch;b.Replace fuse;c.Check and tighten the power adapter;d.Repair or replace the cable | |
The cable drop is too large:a.Line is too long b. The cable section is too small | a.Remove excess c able b.Cable with larger cross section | |
The capacitor burned. | Replace the same type of capacitance.(Send the maintenance point maintenance) | |
Shaft and bearing die | change bearing (Send the maintenance point maintenance) | |
Impeller stuck | Use the screwdriver to move the blade end shaft, the rotating flexible or open the pump body to clear debris. | |
Winding of stator broken | Replace winding coil (Send the maintenance point maintenance) | |
Motor running, but not water | Pump rotation direction is wrong | Conversion motor in which the two phases of the wiring (three-phase motor) |
The pump is not filled with water | To pump water into the pump body. | |
damaged impeller | change impeller | |
The water level is lower than the bottom valve | Adjust the inlet pipe to pump valve in the water | |
Water suction pipe leakage | Check the sealing condition of each joint of the suction inlet pipe. | |
The water level is too low, which is lower than the limit of the pump. | Adjust the installation height of the pump or choose the appropriate pump. | |
Water in a pipe or pump chamber causes icing. | After the ice has been turned on. | |
Insufficient pressure | Pump selection is not correct. | Choose the right water pump. |
The water inlet pipe is too long, or too many bends, the diameter of the water inlet pipe is not selected according to the regulation. | Selection of the provisions of the pipe diameter, so that the design of the inlet pipe is a little shorter。 | |
Foreign matter blocking inlet pipe, filtering net or pump cavity | Clean the pipe, valve or pump chamber to remove debris | |
Motor voltage is too low, the wire is too long | Check the end voltage of the motor and the cross section of the wire | |
Pump vibration | Pump is not fixed in the base | Tighten the anchor bolts |
There is a foreign body in the pipe or pump cavity | Check, clean pipes and water pumps. | |
Stability of the base is not enough | Installation of a more stable base | |
Motor stator winding burn or intermittent work | Motor overload running time is too long | The installation of the valve outlet, reduce water |
Impeller stuck or long time overload operation | Removal of impurities in the pump cavity, as far as possible in the rated flow of water pump work | |
Ground faults or cable damaged by lightning, electric pump | Find the reason, change the winding coil | |
Water leakage at the support | Mechanical seal with impurities | Clean or replace mechanical seals |
