204 Introduction to the basic knowledge of mechanical seal Mechanical seal (end face seal) is a device used to solve the sealing between rotating shaft and engine body. It is a device to prevent fluid leakage, which is composed of at least one pair of fluid pressures on the end faces perpendicular to the rotation axis, the elastic force (or magnetic force) of the compensation mechanism, and the auxiliary seal, which are kept together and sliding relatively. It is commonly used in pumps, compressors

204 Misuse of mechanical seal manufacturers 1. The greater the spring compression, the better the sealing effect. In fact, too much spring compression can lead to rapid wear and instant burning of friction pairs; Excessive compression makes the spring lose the ability to adjust the end face of the moving ring, leading to seal failure. 2. The tighter the dynamic ring seal diagram is, the better. In fact, too tight the dynamic ring seal is harmful and useless. First, intensify the seal ring and shaft

[ Industry News ] 204 Causes of penetration caused by mechanical seal

204 Cause of mechanical seal leakage (I) Leakage caused by pressure 1. Fault I: Mechanical seal leakage caused by high pressure and pressure wave Cause: The specific pressure of spring and the total specific pressure design are too large. When the pressure in the seal cavity exceeds 3MPa, the specific pressure of the seal face will be too large, the liquid film will be difficult to form, the seal face will be severely worn, and the heat generation will increase, resulting in

[ common problem ] 204 Basic knowledge of mechanical seals

204 Basic knowledge of mechanical seal 1. Basic concept of mechanical seal: mechanical seal refers to a device to prevent fluid leakage, which is composed of at least one pair of end faces perpendicular to the rotation axis, under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, and with the cooperation of the auxiliary seal, to keep sticking and sliding. The auxiliary seal of compensation ring is metal bellows, which is called bellows machine

204 Basic structure and primary characteristics of mechanical seal Mechanical seal is a kind of equipment used to deal with the seal between rotating shaft and engine body. It consists of at least one pair of end faces perpendicular to the rotation axis, sticking and sliding together under the effect of fluid pressure and tissue elasticity (or magnetic force) compensation and the cooperation of auxiliary seals to avoid fluid leakage. It is commonly used in pumps, compressors, anti leakage devices

204 Mechanical seal manufacturers teach you the washing skills of seals! Features of mechanical seal flushing technology The purpose of mechanical seal flushing is to prevent the accumulation of impurities, prevent the formation of air bags, maintain and improve lubrication, etc. When the flushing fluid temperature is low, it also has a cooling effect. Now Hengda Mechanical Seal will explain the technical features of mechanical seal flushing. 1. Internal scour and forward scour

[ Company News ] 204 Several mistakes should be noticed when the mechanical seal manufacturer overhauls!

204 What are some mistakes that should be paid attention to during the maintenance of mechanical seals? 1. The greater the spring compression, the better the sealing effect. In fact, the spring compression is too large, which can lead to rapid wear and instant burning of the friction pair; Excessive compression makes the spring lose the ability to adjust the end face of the moving ring, leading to seal failure. 2. The tighter the dynamic ring seal diagram, the better. The driving ring seal ring is too tight
