Cause and Solution of Failure of GDL Vertical Multistage Centrifugal Pump

GDL Vertical Multistage Centrifugal Pump Failure A: In the event of vertical multi-stage pump non-suction pressure gauge and vacuum gauge pointer violently beating phenomenon.

Reason for the malfunction: Suction stroke is too high, perfusion water is not sufficient, piping and instrumentation joints are not normal air out.

Solution: Check the end of the valve there is no leakage, then hire enough water, tighten the leak.

GDL vertical multistage centrifugal pump failure two: Vertical multi-stage pump is not suction vacuum gauge may be a high degree of vacuum.

Cause of the malfunction: clogged filter, the end of the valve did not open In other words, blocked, water pipe resistance is too large.

Solution: Check 说 A8 晃 Ao H 孀 H 盖 盖 盖 似 似 似 似 似 似 like ao?

GDL vertical multistage centrifugal pump failure three: vertical multi-stage pressure gauge pressure but still can not water.

Reason for the malfunction: impeller blockage, may be encountered in the outlet resistance is too large, the direction of rotation is not correct, the outlet pipe valve is not open.

Solution: Double check 缗 short tube. Detection of two-phase motor tuning. Start the outlet valve. Remove the dirt inside the impeller.
