Frequently asked questions
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
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)
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.
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.
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 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|
