Matters needing attention in the use of equipment of mechanical seal manufacturers The quality of mechanical seals needs to be very high, because it is a kind of oil seal equipment of rotating machinery. It is a pair of or more pairs of end faces perpendicular to the rotating axis. Under the effect of the mechanical seal pressure of fluid pump and the elastic force (or magnetic force) of compensation arrangement, as well as the cooperation of auxiliary seals, the mechanical seals adhere to sticking, swallowing and relatively sliding

Precautions for kettle mechanical seal when checking the surface of hard ring The failure of rubber ring is related to the use mode. Usually, high pressure is a reason for the failure of imported pressed O-ring. When it is found that the O-ring becomes rectangular or the ring becomes hard, the compression amount needs to be adjusted, otherwise it will become hot. (1) Hot cracking; (2) Ceramic ring fracture; (3) Nick; (4) The coating falls off. ceramics

Cause analysis and treatment measures for leakage of mechanical seal for kettle In centrifugal pump and reaction kettle, the seal between rotating pump shaft and fixed shell is called shaft seal device. At present, centrifugal pumps and reactors are generally used for sealing and mechanical sealing. Mechanical seals are widely used because of their low leakage, long service life, low power loss, no need for frequent maintenance and little impact on the environment. Mechanical density

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

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

With the requirements of production safety and environmental protection, the application of mechanical seal for kettle is more and more extensive. At present, most of the rotating equipment in most enterprises use mechanical seals to protect the dynamic and static sealing surfaces from leakage. However, mechanical seals are relatively precise parts of the equipment, which require high technical personnel in the process of operation and maintenance,
