What are the bearing types of water pumps?
The bearing types of water pumps mainly include the following:
1. Angular contact ball bearing: This is a specially designed rolling bearing with an internal contact angle design, which enables it to bear radial loads and axial loads at the same time. By optimizing the contact angle and the inner and outer ring structures, the bearing's accuracy and speed capability can be improved to meet the needs of high-speed operation of water pump motors.
2. Tapered roller bearings: Compared with angular contact bearings, tapered roller bearings can withstand greater radial and axial loads. It can control the front and rear clearance of the bearing by adjusting the angle of the ring or the back to adapt to the working conditions of different water pump motors.
3. Needle roller bearings: This type of bearing is mainly used to bear smaller radial and axial loads. Due to its small inner diameter and limited load-bearing capacity, it is more suitable for use in water pump motors with lower requirements.
4. Thrust ball bearing: The interior of the thrust ball bearing is composed of a washer-shaped raceway ring with a raceway, a ball and a cage. It can only bear axial loads but not radial loads. This type of bearing is usually used in general motor equipment to support axial loads.
5. Cylindrical roller bearings: The rollers of cylindrical roller bearings are guided by two flanges of the bearing rings. The cage rollers and the guide rings form a combination that can be separated from the other bearing ring. This type of bearing can withstand heavy loads and impact loads, so it is often used in conjunction with angular contact ball bearings in large water pump motors.
6. Deep groove ball bearings: This is a widely used bearing type in low-speed water pumps. It has a simple structure and can withstand a certain load. Common models include the 60 series, such as 6001, 6201, 6301, etc.
In addition, other types of bearings such as sliding bearings may also be used in water pumps. In general, the selection of bearing type for water pumps should be based on the motor model, design requirements, and use environment to ensure the normal operation and long-term stability of the water pump.
