Mechanical Seals For APV Pumps are often used as waterproof measures at the connection of APV pumps in industry, so how does it work?
Mechanical seals are mainly composed of two parts: a dynamic ring and a static ring. The dynamic ring structure contains components such as springs and dynamic ring seats. The dynamic ring and the static ring fit tightly together through the extrusion of the spring,thereby preventing water leakage in the volute. If the mechanical seal is damaged, the water pump will have varying degrees of water leakage. Today we will learn about the main materials of Mechanical Seals For APV Pumps.
Mechanical Seals For APV Pumps mainly include graphite, silicon carbide and stainless steel. The selection of these materials is based on their high temperature resistance, corrosion resistance and hygienic properties to ensure the normal operation of the pump and extend its service life. The characteristics and application scenarios of different materials are different.
Graphite sealing rings have excellent high temperature resistance and are suitable for sealing needs in high temperature environments. It also has good self-lubrication and corrosion resistance, and is suitable for pumps in the food and pharmaceutical industries.
Silicon carbide sealing rings have high hardness, high wear resistance and corrosion resistance, and are suitable for harsh working environments. It is often used in situations where high-strength sealing is required.Stainless steel materials have good corrosion resistance and strength, and are suitable for various industrial environments. It is often used to manufacture pump housings and key components.We have a preliminary understanding of the materials of Mechanical Seals For APV Pumps, and we must also pay more attention to their maintenance and repair.
The sealing ring sometimes leaks, so how to determine the cause of the leakage and solve it?
If the mechanical seal of the water pump is found to be leaking, it can usually be determined that the mechanical seal is damaged. After disassembling and checking the damaged parts of the mechanical seal, there are two common situations:
1.The inner ring of the moving ring and the shaft are leaking at the contact point, which may be due to impurities or particulate matter in the medium. The solution is to check whether there is a filter at the front water inlet and confirm whether the filter is damaged.
2.The outer ring of the static ring leather is damaged, which is usually caused by dry grinding without water or dry grinding caused by cavitation. The solution is to exhaust before use and check whether the pipeline has the hidden danger of cavitation.
The maintenance and replacement cycle of Mechanical Seals For APV Pumps depends on the use environment and working conditions. In order to ensure the sealing effect and service life, it is recommended to check the wear of the seals regularly, replace the severely worn parts in time, and keep the seals and shaft surfaces clean and lubricated. Mechanical seals are important parts of the pump and are responsible for preventing fluid leakage. By understanding their working principles and common problems, you can better maintain and care for the pump to ensure its normal operation.
