Pump industry suppliers to tell you: stainless steel screw pump wear parts should be how to repair

the cause of the screw pump motor overheating have?

screw pump motor overheating is the problems that arise in the working process of the specific reason is as follows:

1, the use scope ( Capacity and head) More than the gear oil pump design requirements: choose by series spectrum suitable motor

2, medium weight exceed the gear oil pump motor: configure appropriate gear oil pump with motor

3, packing gland pressure too tight or too tight mechanical seal spring: to adjust the amount of spring compression gland or mechanical seal

4, pump assembly quality is poor, there are friction or different heart: motor and pump shaft check assembly quality, eliminate assembly problems.

screw water pump long slots on the positioning plate has turned to the limit, the positioning pin still cannot be inserted into the hole, need to reinstall the joint lever assembly, change the spline coordinate position, adjust, tighten the two retaining bolt positioning plate and the fixed bolt joint lever assembly. Finally, should pull (joint lever assembly for several times repeatedly, movable jaw coupling should slide freely, from the peep hole observation, two teeth coupling joint position should be full tooth, the separation position should be full release.

dip a stainless steel screw pump parts wear and how to repair

in the use of stainless steel screw pump, if how to wear the pump valve equipment parts to repair it, this is every machinery factory is a headache thing, because of the water pump valve equipment use after a period of time will appear some corresponding wear.

stainless steel screw pump in use there will be some wear conditions, such as gear wear and tear parts mainly tooth meshing of the working face and the gear involute, the plane. Mild wear, tooth surface grinding oil bill chan, two platforms and lapping repair the light on the tablet. Face serious wear and tear of the gear should be replaced when new gear, if only the ends of the gear surface wear, light on the surface grinding machine grinding.

stainless steel screw water pump axis wear mainly because on both ends of the shaft and friction and wear between the supporting roller, the smaller the diameter of axle. If it is minor wear and tear, through a layer of hard chromium plating, to increase the shaft diameter size, make repair of the shaft, its body surface wear mainly oil absorption period of circular arc form working face. If there is a slight wear and can be used after oil bill chan grinding deburring.
