What’s the maintenance and assembly methods of koyo water pump bearings?

The automobile koyo water pump bearings is a bearing. The cage material is usually made of reinforced nylon 66. The material of the sealing ring is generally made of nitrile rubber. When the requirements are high, the fluorine rubber sealing ring can also be used.

Prevention of assembly of foreign bodies
When the imported koyo water pump bearings are dynamically balanced on the rotor, it is easy to put the iron filings generated during the dynamic balance into the inside of the imported bearings. Therefore, it is better to do the dynamic balancing before loading the imported koyo water pump bearings. Some manufacturers are convenient for assembly.

When assembling, apply some oil or grease to the imported koyo water pump bearings chamber to lubricate the effect. But it is often difficult for the operator to control the amount. If the oil or grease accumulates more in the imported bearing housing? Even when the inlet bearing rotates, it is easy to enter the inside of the inlet koyo water pump bearings along the shaft. It is best not to apply oil or grease to the imported koyo water pump bearings chamber. If it is not coated, it must be controlled and not accumulated in the imported bearing chamber.

Prevention of paint rust
The characteristic of paint rust is that it is mostly in the sealed motor. The motor sounds very well when assembled. But after some time has been put in the warehouse, the abnormal noise of the motor is greatly removed. The pump shaft is connected to the koyo water pump bearings. Rusty phenomenon. In the past, many manufacturers thought that it was a problem of importing koyo water pump bearings. After our constant publicity. The motor factory has realized that it is mainly a problem of insulating varnish. This problem is mainly caused by the acidic substance volatilized by the insulating paint forming a corrosive substance under a certain temperature and humidity. Corrosion of the inlet koyo water pump bearings leads to damage of the imported bearing. This problem can only be achieved by using a good insulating varnish and ventilating it for a period of time after drying.

Selection and control of shaft and inlet bearing chamber tolerances
The pump shaft and the imported bearing should be rotated to the flexible and unblocked feeling after being pressed into the imported koyo water pump bearings. If the obvious rotation is not flexible, it means that the size of the shaft is too large and the tolerance should be lowered. For example, if the pump shaft is pressed into the shaft and the shaft is rotated by hand, there is a clear “sand” feeling. The tolerance of the shaft is too large or the roundness of the shaft is not good. Therefore, it is necessary to control the roundness when controlling the tolerance of the shaft and the koyo water pump bearings chamber. Many domestic manufacturers only control the tolerance and do not control the roundness.

Assembly method of imported koyo water pump bearings
Because the imported koyo water pump bearings are high-precision products, the pump shaft couplings are easily damaged due to improper assembly of the pump shaft and the imported bearing channel. When the imported bearings are assembled, there should be a special mold that cannot be knocked at will. When pressing the shaft, only a small circle is required. When the large circle is pressed, only a large circle of force is applied. It is required to use air pressure or hydraulic pressure during assembly. When the press is installed, the upper and lower touches should be outside the horizontal state. If it is tilted, the inlet bearing channel will be damaged due to the force, and the imported bearing will produce a sound.
