Product Description

Product Description

In the slurry pump bearing assembly, lubrication method of the bearing is roughly divided into grease lubrication and oil lubrication, and the choice of the way is related to the type, size and operating conditions of the bearing. In grease lubrication and oil lubrication, grease lubrication is the most used, about 80% of rolling bearings are using grease lubrication.

 

Characteristics of grease lubrication

A: The lubrication device is simple. If sealed bearings or non-sealed bearings that do not require grease are used, no additional lubrication is required (in contrast, oil lubrication systems require oil pumps, tubing, fuel tanks, etc.).

B: Grease is not easy to leak, bearing seal structure is relatively simple,

C: Easy maintenance of bearings.

D: The grease has a sealing effect to prevent external dust, moisture and other impurities from invading the bearing.

E: Easy to improve the cleanliness of the mechanical device.

 

II The characteristics of oil lubrication

A:suitable for high-speed rotation

B: good high temperature stability, suitable for use at high temperatures.

C:can take away the internal friction heat of the bearing, good heat dissipation. When the ambient temperature of the bearing is high, oil lubrication can play a cooling role.

D: easy to remove the wear particles and dust inside the bearing.

E,:can be used with gear and other bearing parts around the same lubricant,  achieving common lubrication. 

Detailed Photos

The slurry pump is primarily used for conveying slurry with particles, which makes it imperative for the pump to have high wear resistance. There are two types of wear-resistant materials currently available: high chromium alloy and wear-resistant rubber. However, what distinguishes these two materials? 
High chromium alloy is a metal material that contains 26% to 27% chromium. Chromium is a metal element that possesses relatively high hardness, and hence, the level of chromium content determines the wear resistance of the material. However, it is a common misconception that the higher the chromium content, the better the material. As we all know, the higher the hardness, the more brittle it is, as is the case with glass. Therefore, the high chromium alloy material used in the overflow parts of the slurry pump is the best proportion after numerous tests, providing the perfect balance of wear resistance and toughness.

The wear-resistant rubber material is a rubber lining material that consists of a metal skeleton inside and an outer layer of wear-resistant rubber lining.

So, which of these two materials is better? Each has its advantages and disadvantages:
1. Rubber-lined pumps are lighter in weight and less expensive than high chromium alloy pumps.
2. Rubber lining pumps are suitable for conveying slurry without sharp particles. If there are sharp corners, it is easy to scratch the rubber, which will significantly reduce the service life.
3. Rubber-lined pumps have better corrosion resistance than high chromium.
