Water pump shaft bearing work pay attention to the problem

The pump shaft bearing work pay attention to the question 1, assembly to prevent foreign body? Imported bearing when loaded on the rotor to do dynamic balance will be generated when the dynamic balance of iron into easily imported bearings 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 on the imported bearing indoor storing up more? Imports in a water pump shaft bearing rotates along axis to the INA imported bearing internal easily. Imported bearing chamber is best do not apply oil or grease if must apply to control shall not be in imported bearing indoor have left. 2, paint, rust prevention? 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 even imported 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 the corrosion cause INA bearing damage. The problem now is only to choose good insulating varnish and ventilation after a period of time after baking assembly. 3, shaft and imported bearing chamber tolerance selection and control? After imported into the bearing pressure bearing water pump shaft should be flexible rotation without blocking. 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 to control the import of shaft and bearing chamber when the tolerance is to control the roundness at present many domestic manufacturers to control the tolerance not only to control the roundness. 4, imported bearing assembly way? Import bearings are high precision products for water 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. Imported 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. Jiaxing bearing co. , LTD.
