1、 Selection of sealing ring

The selection of sealing rings for gear pumps should be based on the properties of the medium, the working conditions of the pump, and the requirements for use. Choosing suitable sealing rings can effectively ensure the normal operation of the pump. For flammable, explosive and other hazardous media, reliable sealing rings should be selected to improve the safety performance of the pump. If the viscosity of the liquid is high, wear-resistant and high-strength sealing rings should be used. In addition, attention should be paid to whether the material and size of the sealing ring meet the standard requirements to ensure the normal operation of the pump.

 

2、 The function of the sealing ring

The sealing ring of a gear pump is an important component in a gear pump, which has two main functions: on the one hand, it prevents the liquid inside the pump from spilling out, and on the other hand, it prevents the entry of external media, thereby ensuring the normal operation of the pump. Because liquid leakage can lead to energy and material waste, while the invasion of external media can affect the sealing of the pump, causing equipment failure and danger. Therefore, the sealing ring is an important guarantee for the normal operation of the gear pump.

3、 Maintenance of sealing ring

The maintenance of the sealing ring of the gear pump is very important, and its service life depends on multiple factors such as the material, manufacturing process, and usage environment of the sealing ring. Therefore, when using a gear pump, it is important to regularly check the wear of the sealing ring. If any signs of wear, aging, or cracking are found on the sealing ring, it should be replaced promptly. In addition, lubricants should be selected reasonably to ensure the lubrication and lifespan of the sealing ring.

 

4、 Types of sealing rings

Gear pumps typically use two types of sealing rings, namely axial sealing rings and radial sealing rings. Axial sealing rings are usually made of rubber or plastic and coated with special lubricating grease. The function of this sealing ring is to prevent the axial leakage of liquid inside the pump. The radial sealing ring is mainly composed of mechanical seals or packing seals, and its function is to prevent the medium from leaking radially. The application of these two types of sealing rings depends on the specific situation.

 

 

5、 Conclusion

In short, the sealing ring of a hydraulic gear pump is an important component to ensure the normal operation of the pump. Its function is to prevent leakage inside the pump and the invasion of external media, thereby ensuring the normal operation of the pump. When using a gear pump, suitable sealing rings should be selected, and regular inspections and maintenance should be carried out to ensure the efficiency and lifespan of the pump.
