YZP Type Motors Analyze The Reasons
When the motor is running, YZP Type Motors you can use a screwdriver, the tip of the bearing on the outer cover, the ear close to the screwdriver wood handle monitor the sound of the bearing. Such as the rolling body in the inner and outer ring in the vague rolling sound, and the sound monotonous and uniform, people feel relaxed, then the bearing is good, the motor is running normally. YZP Type Motors If you hear an abnormal sound, you should analyze the cause and process it.
1.1 to hear the obvious rolling rolling and vibration sound, YZP Type Motors indicating that the bearing clearance is too large or serious wear and tear, need to be replaced.
1.2 rolling voice dumb, heavy tone, YZP Type Motors indicating that the bearing grease is dirty, there are impurities intrusion, need to use kerosene cleaning bearings and replace the new lubricants.
1.3 rolling body with irregular impact, YZP Type Motors indicating that the individual bearing rolling body, need to be replaced.
1.4 approximate whistle of the call, mixed with the rolling of the rolling sound, indicating the lack of grease grease or lubricants improper choice, YZP Type Motors need to add clean lubricants or replace the appropriate lubricants.
2, rolling bearing heat causes and treatment methods
2.1 motor shelved for too long, YZP Type Motors grease deterioration, hardening; should replace the new grease.
2.2 Lubricating oil in the bearing chamber is too large or too small, should be between the bearing chamber volume of 1 / 3-2 / 3; and according to the motor requirements of the regular quantitative plus the same type of lubricating oil.
2.3 There are debris in the bearing chamber, need to use kerosene cleaning bearings and replace the new lubricants.
2.4 bearing wear is too large or inner ring and outer ring rupture, should replace the same type of new bearings.
2.5 motor running vibration, YZP Type Motors coupling improper installation, the belt is too tight and the shaft bending, will cause the bearing heat; should be excluded according to the circumstances.
2.6 bearing not fit with the shoulder, open the bearing cover, YZP Type Motors with a copper rod to resist the bearing inner ring with a hammer symmetrical knock into.
2.7 end cover or bearing cap assembly is bad, should be re-assembled, so that both ends of the end cover and the seat with a good mouth, and diagonal tighten the bearing cap fastening bolts.
2.8 The performance of rolling bearings depends not only on the accuracy of the manufacturing of the bearing itself, but also with its matching shaft and hole size accuracy, YZP Type Motors shape and position tolerance and surface roughness, the choice of cooperation and installation is correct or not.
If the bearing inner ring and the shaft with too tight, or bearing outer ring and end cap bearing chamber with too tight, that is, when the public surplus is too large, then the assembly will make the bearing gap becomes too small, sometimes even close to zero. YZP Type Motors So that the bearing rotation is not flexible, YZP Type Motors the operation will be hot, or even burn the bearings.
The motor is turned on, the motor does not turn but there is a buzzing sound may be reasons: ① due to power supply problems, resulting in single-phase operation; ② motor load overload; ③ dragged mechanical stuck; ④ winding motor Rotor circuit open circuit into a broken line; ⑤ stator end of the head position wrong, YZP Type Motors or broken, short circuit. Processing method: the first case to check the power cord, the main check the motor wiring and fuses, whether there is line damage; the second case will be unloaded after the motor unloaded or semi-loaded start; the third case is estimated to be due to be Drag the device failure, YZP Type Motors uninstall the dragged device, YZP Type Motors from the dragged device to find the fault; the fourth case check brush, YZP Type Motors slip ring and starting resistor contactor of the contact situation; the fifth case to re-determine the three-phase And check whether the three-phase windings are broken and shorted.
