How to check and prevent the water pump bearing is damaged, you understand

How to check and prevent the water pump bearing is damaged, you understand? Power operation, starting from the no-load speed, slowly up to the rated operating conditions. Test run to check the items, whether there is abnormal sound, water pump shaft bearing temperature, lubricant leakage or discoloration, and so on. If discovery is unusual, should immediately stop, check machine, when it is necessary to remove the bearing inspection. ( 1) Assembly to prevent foreign body: bearing in loaded on the rotor dynamic balance when it is easy to dynamic balance of iron into the bearing inside, so it is best to install bearing before do dynamic balance. There are some manufacturers in order to convenient assembly, assembly in bearing indoor coated with some oil or grease lubrication effect, but usually operators good amount of it is hard to control, if oil or grease in the bearing interior storing up more, in the water pump shaft bearing rotates along axis to the bearing inside easily. Bearing chamber it is best not to apply oil or grease, if must apply to control shall not be storing up in bearing interior. ( 2) Paint the rust prevention: paint rust is characterized by multiple in sealing type motor, the motor sound is very good, when it is assembled but put some time in the warehouse, the motor sound is very big, remove the water pump shaft bearing has serious rust phenomenon. Many manufacturers will think is a problem of bearing before, after our propaganda, motor factory now have realized mainly is a question of insulating varnish. Acid varnish comes out of the problem is mainly due to the formation of corrosive substances under certain temperature and humidity, the bearing channel after corrosion result in bearing damage. The problem now is only to choose good insulating paint, after drying and ventilation assembly after a period of time. ( 3) Shaft and the bearing chamber tolerance selection and control: water pump shaft even after bearing pressure into the bearing should be flexible rotation without blocking. If there are any obvious rotation is not flexible, indicates the size of the shaft is too big, tolerance to downgrade. Such as water pump shaft bearing pressure into the shaft by hand after the rotation is obvious 'sasha vujacic' feeling, may be the shaft or shaft roundness tolerance is too big. When control the shaft and the bearing chamber tolerance so also want to control the roundness, at present many domestic manufacturers to control the tolerance, not to control the roundness.
