The mechanical seal manufacturer introduces the role of the seal. First, improve the efficiency of the machine 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 mechanical efficiency of the machine

Does the mechanical seal include oil seal? The mechanical seal manufacturer tells you! Mechanical seals cover a wide range. It can be seen that this piece can help the equipment to create better sealing conditions, and can give the equipment more rapid operation. Although its structure is complex and precise, it is also because of this, so it is easy to use. Does the seal actually include an oil seal? 1. The oil seal is generally tight

204 Overview 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 to keep the joint and relative sliding, and is commonly used in pumps, compressors, reactions

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 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

The reason for the leakage of newly installed mechanical seal after it is put into operation is mostly the installation problem. 1) The designed face specific pressure is too small to meet the face specific pressure required by the mechanical seal; 2) The compression of mechanical seal spring is too small; 3) The roughness of mechanical seal end face does not meet the requirements; 4) The flatness of mechanical seal end face is not enough; 5) Mechanical seal ring under pressure and

The mechanical seal manufacturer explained the seal failure. 1. The seal failure is mainly caused by the following three reasons: (1) When the sealing surface is opened and the mechanical seal is repaired, 85% of the seal failure is not caused by wear, but has leaked before wear. As soon as the sealing surface is opened, solid particles in the medium enter the sealing surface under the action of liquid pressure. After the sealing surface is closed, these solid particles are embedded

Mechanical seal manufacturers have several structures to enhance lubrication. 1. End face eccentricity: for general mechanical seals, the center of the moving ring, the center of the stationary ring and the center line of the shaft are all in a straight line. If the end face center of a ring in the moving ring or the stationary ring is made to be offset from the center line of the shaft by a certain distance, the ring can constantly bring lubricating fluid to the sliding surface for lubrication when rotating. It should be noted that

204 Service Life and Reliability of Mechanical Seals I Service Life of Mechanical Seals Mechanical seals rarely fail due to long-term wear and tear, and other factors often promote premature failure of pump mechanical seals. Therefore, the life of the seal should be regarded as a statistical quantity of the kettle mechanical seal, and it is difficult to obtain an accurate value. For example, mechanical seals used in some sewage pumps,

204 The mechanical seal manufacturer tells you the inspection process of mechanical seal! Mechanical seal maintenance procedures To master mechanical seal maintenance and repair, first know the working principle of mechanical seal. The mechanical seal is a sealing device composed of two sealing elements (static ring and dynamic ring) perpendicular to the shaft, smooth and straight surfaces that stick together and rotate relative to each other. It depends on

Let 204 mechanical seal manufacturer tell you the working principle of mechanical seal! Mechanical seal is a shaft seal device that can prevent leakage by a pair or several pairs of end faces that slide relative to the shaft under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and are matched with auxiliary seals. Selection of common materials for mechanical seal: purified water; normal atmospheric temperature; (Dynamic) 9CR18, 1CR13
