Water pump bearings work pay attention to what problem

Water pump bearing in loaded on the rotor dynamic balancing is easy to cause the iron into some problems such as water pump bearings bearing internal influence water pump bearing performance and life. 1, how to prevent foreign body assembly? Water pump bearings 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 the imported bearing before do dynamic balance. There are some manufacturers in order to convenient assembly? When assembling imported bearing interior with some oil or grease on the lubrication effect? A good amount of operators but often it is hard to control? If oil or grease in the bearing indoor storing up more? In the water pump shaft water pump bearing rotates along axis to the INA bearing internal easily. Bearing chamber is the best do not apply oil or grease if must apply to control shall not be storing up in bearing interior. 2, how to prevent rust paint? Rust paint is characterized by multiple in sealing type motor? Motor sound is very good when it is assembled? After some time, but in the warehouse? Motor sound change greatly remove the water pump shaft water pump bearings have serious rust phenomenon. Many manufacturers will be considered before import bearing problems? After our propaganda? Motor factory now have realized mainly is a question of insulating varnish. Varnish comes out of the problem is mainly due to acid corrosion formed under certain temperature and humidity of the material? The imported bearing channel after corrosion lead to damage of INA bearings. The problem now is only to choose good insulating varnish and ventilation after a period of time after baking assembly. 3, shaft, and the choice of tolerance and control water pump bearing room? Water pump shaft even after the water pump bearing pressure into the water pump bearing should be flexible rotation without block. If you have obviously not flexible rotation? Indicates the size of the shaft is too big? Tolerance to downgrade. Such as water pump shaft even imported bearing pressure into the shaft by hand after the rotation have obvious 'sasha vujacic' feeling? Could be the shaft or shaft roundness tolerance is too big is not good. So the good control of axis and water pump bearing chamber tolerance also want to control the roundness at present many domestic manufacturers to control the tolerance not only to control the roundness. 4, water pump bearing assembly way for water pump bearing is high precision products pump axle shafts, such as improper assembly is easy to cause damage to even import water pump shaft bearing channel which INA imports bearing damage. Water pump bearing should have a dedicated mold can't knock when it is assembled in only small circle of stress when the pressure into the shaft? Pressure can force the circle circle. Require the use of pneumatic or hydraulic assembly? To touch up and down when pressed to outside the state level is tilt causes the import bearing channel for mechanical damage? Guide ring and make the import bearings. Water pump bearing on to the choose and buy a: auto water pump bearing manufacturing clearance should be?
