乐发IV

乐发IVAfter the start of the pump, there is usually air in the pump or gas accumulation in the intake pipe, or unsatisfactory irrigation and diversion of the bottom valve, serious leakage of vacuum pump filler, inadequate closure of gate valve or clap door.

乐发IVPump effluent insufficiency elimination method 1:

乐发IVRemove debris, replace damaged rubber pad, change valve direction;

Compress or replace new packing, close gate valve or clap door;

Increase the amount of irrigation and drainage until no bubbles occur at the outlet screw plug.

Replace the cracked pipe, lower the head, and press the nozzle of the pump into the water for 0.5 meters.

When starting, the pump does not turn: the packing is too tight or the impeller and pump body are blocked by debris, or the pump shaft, bearing, leakage ring rust, or the pump shaft severe bending.

乐发IVPump effluent insufficiency elimination method 2:

乐发IVRelax the packing and dredge the diversion tank.

Remove the pump body to remove impurities and rust; remove the pump shaft to correct or replace the new pump shaft. There are screw pumps, slurry pumps, multi-stage pumps or water ring vacuum pumps with fillers.

乐发IVPump fever bearing damage:

The clearance of dynamic bearing or bracket cover is too small.

乐发IVThe pump shaft is bent or two axes are not concentric; the tape is too tight;

乐发IVLack of oil or poor oil quality;

乐发IVThe balance hole on the impeller is blocked and the impeller loses balance, which increases the thrust to one side.

Pump effluent insufficiency elimination method 3:

乐发IVReplacement of bearings;

乐发IVRemove the back cover and install gaskets between the bracket and the bearing seat.

乐发IVAdjust the concentricity of the pump shaft or the two axes, and loosen the belt tightness properly.

Add clean butter, which accounts for 60% of the free space in the bearing.

乐发IVClear the blockage in the balance hole.
