Requirements of mechanical seal on seal ring The seal ring is the general name of dynamic ring and static ring (the same below), and 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. Sufficient strength and rigidity: no damage under working conditions (such as pressure, temperature, sliding speed, etc.), and deformation shall be as far as possible

Several external factors that affect the effect of mechanical seal are insufficient machining accuracy. There are many reasons, some of which are insufficient machining accuracy of mechanical seal itself. This reason is easy to attract people's attention and find. But sometimes the machining accuracy of other parts of the pump is not enough, which is not easy to attract people's attention. For example: pump shaft, shaft sleeve, pump body, seal chamber

How should the kettle mechanical seal be assembled? (1) The assembled parts must meet the specified technical requirements, and any unqualified parts cannot be assembled. For this reason, the parts must be strictly inspected before assembly. (2) The correct fitting method must be selected to meet the requirements of fitting accuracy. A lot of work in mechanical seal repair is to restore mutual matching

Mechanical seal overview 1. Define 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 relative sliding. 2. Basic structure Mechanical seal generally consists of four parts: ① It consists of stationary ring (stationary ring) and rotating ring (moving ring

The wear amount and service life of the mechanical seal manufacturer I. About the service life of the mechanical seal, the main wear part is the end face of the seal friction pair, because the wear amount of the seal end face is not large under normal working conditions, such as the graphite friction pair with a balance coefficient of 0.75, the wear amount per hour in water and oil is about 0.1 μ m, that is to say

Five tips to solve the problem of water leakage of mechanical seals used in kettles. The feature of mechanical seals is that they can be used for various equipment, especially equipment such as reaction kettles and pumps. Because such equipment has high sealing requirements and cannot contain impurities, they are used more frequently. The problem of water leakage is really worrying. Water leakage causes poor sealing effect of sealing elements. This is a taboo for many people. The following five

Why should auxiliary facilities be used for kettle mechanical seal? In fluid machinery (such as pumps, compressors, agitators, centrifuges, etc.), the most demanding parts of mechanical seals for pumps under working conditions are mechanical seals. Bearing axial force like thrust bearing; Export the heat generated like a heat exchanger. It is difficult to achieve static sealing in high temperature, high pressure, corrosion prone and other parts, and the requirements are high
