There are three common faults of DC electric diaphragm pump, they are the normal operation of the motor, but the outlet without water flow out, turn on the power, the motor does not run, the flow and lift are too small, you know these faults are What causes and how to exclude it? The following describes the DC electric diaphragm pump troubleshooting. First, the fault: the motor is operating normally, but the outlet of the water flow out of reason: the import or export pipeline oil plugged Remove the import and export pipe to exclude the pipe blockage Imported pipe tighten the inlet pipe, so that the seal intact pump debris clogging method : Disassemble the pump head, remove debris diaphragm rupture Replace the diaphragm Second, the fault: turn on the power, the motor does not work Cause: The wiring is disconnected or virtual connection The pin is re-fixed connection The pump is not connected to the power supply Troubleshooting: Power supply motor fault repair or with the replacement of the motor transformer fault repair or with the transformer Third, the fault: flow and lift are small Cause: The product of the pump inlet tighten the import interface, so that the seal intact clogging in the pump or pipe Remedy: Exclude the pump or pipe debris separator diaphragm rupture Replace the diaphragm motor repair or replace the motor filter clogged filter debris removal filter above DC motor diaphragm pump is a common failure and its troubleshooting methods, if you master I believe these problems will be solved easily when I encounter similar problems in the future A barrier.
