[ Industry News ] 204 Troubleshooting of mechanical seal

204 Mechanical seal fault handling Mechanical seal and other equipment cause large noise and equipment vibration due to long time mechanical movement with large torque and gear box meshing clearance. In addition, the sealing part has been operating at high speed and high temperature for a long time, and oil leakage often occurs at the sealing part. The leakage of sealing parts is caused by the following reasons: 1. leakage due to oil seal quality problems; 2、

[ common problem ] 204 Mechanical seal manufacturer analyzes the cause of penetration

204 The mechanical seal manufacturer analyzed the causes of the penetration. 1) Leakage caused by pressure. 1. Fault 1: Mechanical seal leakage caused by high pressure and pressure wave. Cause: The specific pressure of the spring and the total specific pressure 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,

[ common problem ] 204 Basic knowledge of mechanical seal manufacturer

204 The mechanical seal manufacturer introduces basic knowledge 1. The basic concept of mechanical seal: mechanical seal is 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 auxiliary seals, to keep fit and relatively slide. The auxiliary seal of compensation ring is metal bellows

[ Company News ] The pump mechanical seal manufacturer tells how to play a sealing role?

204 How can the mechanical seal manufacturer tell you to play a sealing role? 1. Push type mechanical seal and non push type mechanical seal Push type mechanical seal refers to the mechanical seal that the auxiliary seal is pushed mechanically along the shaft or shaft sleeve to compensate for the wear of the sealing surface, which is usually referred to as spring pressed mechanical seal. Non push type mechanical seal is used for auxiliary sealing
