What is the working principle of the mechanical seal of chemical centrifugal pump?

　　Chemical centrifugal pump mechanical seal is a mechanical sealing device used in the hydraulic system to prevent liquid leakage, which is composed of a pair of rotating seals and a pair of static seals, generally composed of two different materials, a wear-resistant and corrosion-resistant heat-resistant material, a wear-resistant and corrosion-resistant cold-resistant material.

　　The working principle of mechanical seal of chemical centrifugal pump

　　When the mechanical seal is installed on the pump, due to the pump speed and rotor capacity, the liquid will be pumped out from the tip of the rotor, forming a low pressure at the groove, and the low pressure at the groove will make the liquid flow toward the gap of the rotary seal, which will rotate for this reason, and when the rotary seal is rotating forward, it will push the liquid back to the tip of the rotor, preventing the liquid from flowing out through the gap. On the other hand, a certain amount of pressure is generated between the stationary seals, and when the pressure is sufficient, it presses the liquid back to the rotor tip, thus further ensuring that the liquid is hermetically sealed.

　　When the rotary seals in the process of rotation, due to the weight and stiffness of the rotary seals, a certain amount of friction will be generated, this friction will make the rotary seals produce a slight vibration, this vibration will increase the friction, and make the mechanical sealing device wear and tear is reduced, which can make the mechanical sealing device more durable.

　　The correct installation and use of mechanical seals is crucial to ensure the normal operation of mechanical seals, which need to be installed in accordance with relevant regulations. In addition, it is necessary to regularly check the mechanical sealing device, such as the discovery of anomalies, should be dealt with in a timely manner to replace.

　　In summary, the working principle of the mechanical seal of chemical centrifugal pump is that when the mechanical seal device is installed on the pump, due to the rotational speed of the pump and the rotor capacity, the liquid will be pumped out from the rotor tip, forming a low pressure at the groove, and the low pressure at the groove will make the liquid flow to the gap of the rotary seal, which will rotate as a result of this rotary seal, and at the same time, the static seal will also produce a certain amount of pressure, which will The static seal will also generate a certain pressure to press the liquid back to the rotor tip, thus further ensuring the liquid sealing. In addition, the rotary seal will produce a certain friction in the process of rotation, so that the mechanical sealing device to reduce the wear and tear of the mechanical seal device, thus making the mechanical seal device more durable. Finally, the correct installation and use of mechanical sealing device, regular inspection of mechanical sealing device, timely treatment of abnormal phenomena, can effectively ensure the normal operation of mechanical sealing device.
