Explosion-proof motor bearing temperature through high factors and treatment method

Of explosion-proof motor bearing, high temperature weather is one of the important elements of damage of main bearing, bearing abnormal sound, of course, vibration is larger, unreasonable design forms an explosion-proof motor bearing damage, a network on the basis of understanding the Chinese specification, main share today about the elements of explosion-proof motor bearing temperature through high and treatment method of relevant information. Explosion-proof motor bearing explosion-proof motor bearing temperature through the elements of high & emsp;   1, motor bearings due to long-term lack of oil, the friction loss increased, the bearing overheating.     2, when the motor running, the oil too much or too thick, will also get overheated bearings.     Smooth smooth 3, in changing the oil, because oil mixed with hard grain impurity or bearing cleaning unclean with hard grain impurities, make bearing wear and overheating, that may damage the insulation.     4, due to improper assembly, fixed end cover screw tightness level is differ, forming a straight line between the two bearing hole center is on the inside and outside the circle is not parallel, or bearing turns bearing insensitive, adds load after make the growing friction and heat.     5, belt too tight or motor with passive mechanical shaft center is constantly online, weeks and will make bearing load increases and fever.     6, bearing improper selection or poor quality, such as bearing internal and external ring rust, individual steel ball is not round, etc.     Explosion-proof motor bearing high treatment method 1. Work if the bearing of the motor overheating, should check bearing ball bearing bush of ball bearing can be damaged goods, if there is damage to give correct change. 2, when the smooth change fat, if mixed with hard particles impurities or bearing cleaning not clean, can make the bearing wear and overheating, and may damage the bearings. Bearing and bearing end cover should be after washing clean, smooth change fat again, indoor smooth filled with grease and oil until 2/3.     3, bearing indoor short of oil. Long-term lack of oil running of motor bearing, friction loss increased, the bearing overheating. Regular maintenance, care should be smooth add smooth two-thirds filled with grease oil chamber or add oil to regulate oil level line, to prevent the motor bearing short of oil.     4, smooth fat brand is wrong. To smooth change right type of grease as soon as possible. General should choose 3 lithium base grease or 3 composite calcium base grease.     5, smooth fat embolism in the rolling bearing, should put an end to smooth fat too much in the rolling bearing.     6, smooth fat have impurities, too dirty, too thick or oil ring stuck. Should check the stuck smooth change fat, why stop repair, oil should swap smooth when stick through the big fat.     7, bearing and shaft, bearing and end cover with too loose or too tight, too tight will make bearing deformation, too loose easily attack 'run'. Bearings and shaft too loose when the journal can be coated metallic paint or end of the end cover set set, tight should be reprocessed.     8, belt too tight, too loose, and poor coupling assembly, or electrical and mechanical shaft center is being dragged with continuous line, increase the bearing load and fever. Should adjust the belt elasticity; Correct the coupling.     9, due to improper assembly, fixed end cover screw tightness level differences, formed a line between the two axis center is uneven or bearing outer ring and the bearing rotation is not sensitive, take load after growing friction and heat, should be reassembled.     10, two motor end cover, or bearing cover not assembled, it is usually not parallel to the formation of the bearing is not in the correct position. The two end cover or stop bearing cover mouth flat, tighten the bolt.
