Selection of spring isolator style for planetary wpds250 reducer accessories: generally, self-supporting spring damper is selected, which has the advantages of simple structure and low cost
Low; The spring is recorded and exposed, which is convenient to observe the spring state at any time. The spring to be replaced shall be disposed in advance to avoid excessive corrosion and damage of the spring,
Cause sudden settlement of vacuum pump, equipment damage and pipeline breakage.
Selection of spring: generally, the manufacturer of planetary wpds250 reducer shall select the spring to meet the following requirements: the spring diameter shall not be less than its under rated load
0.8 times the height; The spring must have a certain stroke, and the vortex flowmeter shall be at least equal to 50% of the rated static deflection.
If the bearing is damaged or worn too much, so that the stator and rotor collide, check whether the reducer bearing is loose and whether the stator and rotor are not assembled properly
Good;
The broken bar of cage rotor or loose coil joint of wound rotor cause excessive current of maintenance network and heating. The copper bar rotor can be welded or replaced
The cast aluminum rotor of reducer shall be replaced;
If the winding wiring is wrong, the star is wrongly connected into a triangle, or the triangle is wrongly connected into a star, and the planetary reducer operates under the rated load, it will cause
If the motor is overheated, check and correct it;
