Rubber bearings in water, advantages of rubber bearings

Rubber bearings in water are mainly used in vertical axial flow pumps and mixed-flow pumps. It is especially suitable for circulating water pumps, washing pumps, cooling water pumps, seawater pumps, water supply and drainage pumps in nuclear power stations and thermal power stations. On the other hand, due to the problem of water pollution caused by oil leakage in oil-lubricated bearings, water lubrication has been paid attention to again, and rubber bearings are also widely used in bearings of stern shafts and rudder shafts, as well as spindle bearings of dredger cutting heads.

 

Rubber bearing function:

Rubber bearings are used to support the shaft and bushing. It is divided into copper sleeve rubber bearings, iron shell rubber bearings, bearing strips and full rubber bearings. Manufactured by the molding method. It is mainly used for ship axial flow pumps, deep well pumps, etc., as the support body of slurry blades and pump blades.

 

Advantages of rubber bearings:

1. Small power loss

Generally, the sliding friction between wet rubber and metal is very small, and the special rubber formula developed by our company makes the friction coefficient of the bearing smaller. Comparison of coefficients of friction

 

2. Less wear and tear

It is more resistant to wear than lignum vitae wood (a material for wooden pulleys and wooden bearings), and can last for more than 4 years when the tree needs to be replaced after several months of use, such as rubber bearings.

 

3. It is not easy to damage the shaft and shaft sleeve

Even if sediment and pebbles enter between the shaft and the rubber bearing, the grooves of the bearing that rotate along with the shaft are excluded due to the action of lubricating water. In order to make the most of this property, we have conducted special research on rubber formulations.

 

4. Sound and shock absorption

Because the friction between the rubber bearing and the shaft is very small, the anti-sound and shock-absorbing effect of the rubber is obvious.

 

5. No pollution

Since the lubricating material is water, no lubricating oil is required, so there is no oil pollution.
