Mechanical seal factory tutor you to clean and check! The working principle of mechanical seal requires that there is no impurity inside the mechanical seal. Before assembling the mechanical seal, the moving ring, stationary ring, shaft sleeve and other parts shall be thoroughly cleaned. Key inspection: 1. Whether there are scratches, cracks and other defects on the surface of the moving and stationary rings, which will cause serious leakage of the mechanical seal. If possible, special tools can be used to check the seal

Structural features of 205 type mechanical seal for kettle: 205 type mechanical seal for kettle is double end face, multi spring unbalanced structure. The purpose of sealing is mainly achieved by the pressure difference between the sealing liquid in the sealing chamber and the sealed medium. The sealing liquid needs another set of device to circulate. The whole system is complex. Therefore, it is only used for sealing flammable, explosive, toxic and strongly corrosive media in special occasions. Friction pair

The function of mechanical seal The manufacturer of mechanical seal tells you! 1、 Improve machine efficiency and reduce energy consumption. 1. Reduce the internal leakage, external leakage and penetration of the machine, and improve the volumetric efficiency of the machine. For example, Daqing Refinery will coking 5FDJ5 × 2. The impeller mouth ring of centrifugal pump was changed into mechanical seal, which improved the pump efficiency by 3.6% and 5.6%. 2. Reduce friction loss and improve the

Instructions for use of kettle mechanical seal 1. Mechanical seal (end face 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 cooperation of fluid pressure, elastic force of compensation mechanism and auxiliary seal, to keep sticking and relatively sliding. 2. Mechanical seal for kettle, applicable to all kinds of steel kettle, enamel kettle, glass lined kettle mixing shaft and

Advantages and disadvantages of mechanical seal for kettle 1. Advantages (1) The structure is reliable, and the leakage can be limited to a small amount. As long as the surface roughness and straightness of the main sealing surface can meet the requirements, and as long as the wear resistance of the material is good, the mechanical seal can achieve a small amount of leakage, even the leakage can not be seen by the naked eye. (2) Long life. In the mechanical seal, the main wearing part is the end face of the seal friction pair, because

Normal operation and maintenance of mechanical seal manufacturer 1. Preparations and precautions before startup a. Comprehensive inspection of mechanical seal, accessory devices and pipeline installation is complete and meets technical requirements. b. Static pressure test shall be carried out before starting the mechanical seal to check whether there is leakage of the mechanical seal. If there are many leaks, find out the causes and try to eliminate them. If it is still invalid, it shall be disassembled for inspection

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

The technical requirements of mechanical seal for kettle are that the seal ring is the general name of dynamic ring and static ring (the same below), and it is the main component of mechanical seal. To a great extent, seal ring determines the service performance and life of mechanical seal, so some requirements are put forward for it. There shall be enough strength and rigidity to avoid damage under working conditions (such as pressure, temperature and sliding speed), and the deformation shall be as small as possible,

The mechanical seal manufacturer introduced the system composition shaft seal box. In the past, the shaft seal box containing mechanical seal was a stuffing box designed for soft packing seal. It is not suitable for holding mechanical seals. Not only is the size too small, the gap too narrow, but also the simple cylinder shape is not suitable. The standard of oversized mechanical seal shaft seal box has been formulated abroad. In addition, the United States_ Durametalek and British Fluid
