2) Check valve damaged or contaminated; cleaned or replaced.
3) out of the tube blocked; clear the pipeline.
4) liquid freeze; dissolve the entire dosing system solution.
5) circuit fuse fuse; replace the fuse;
6) The thermal overload relay jumps open in the motor starter; reset the thermal overload device.
7) Cable disconnected; check location and repair.
8) the voltage is too low; test and adjust.
9) Pump is not filled with liquid. Open the outlet valve to pump liquid to empty.
10) Stroke set to zero position; readjust stroke setting.
2, GM metering diaphragm pump out of liquid volume
1) The stroke setting is incorrect; readjust the stroke setting.
2) The pump speed is wrong; Check whether the power supply voltage and frequency are consistent with the motor brand name.
3) lack of liquid absorption; increase the suction pipe diameter or increase the suction head.
4) Pipette leaks; repair pipettes.
5) Suction too high; rearrange the device to reduce suction.
6) liquid close to the boiling point; cooling liquid or increase suction head.
7) leakage of liquid lines or safety valves; repair or replacement of safety valve.
