Various criteria for the life of mechanical seals Because the life of mechanical seals is directly related to the performance and efficiency of equipment, we need to introduce and understand the various criteria for the life of their accessories. It is well known that mechanical seals are one of the basic mechanical components with fine, dense and complex structure. They are the key components of various pumps, reaction synthesis kettles, turbo compressors, submersible motors and other equipment. Its sealing performance and service life depend on many factors, such as type selection, machine accuracy, correct installation and use, etc. According to the different working conditions and the nature of the medium, there are high temperature and low temperature resistant seals, high pressure resistant, corrosion resistant seals, particle resistant medium seals and seals suitable for light hydrocarbon media that are easy to vaporize, etc., according to different uses Choose seals of differe...

The pump mechanical seal means that the installation of the dynamic sealing effect of the installation runs in the pump device, and the leak point of the device needs to be understood during use, so as not to use improper use, the equipment is damaged, and the leakage situation is increased. (1) the seal of the shaft sleeve and the shaft; (2) Sealing between the articles and the bushing; Pump mechanical seal (3) Moving, static ring seal; (4) Sealing of the static ring and the static ring; (5) Sealed end cap and the seal between the pump body. In general, the leakage between the pump is more likely to discover and solve the leakage between the sealing end cap and the pump body, but it is necessary to observe, especially when the working medium is a liquefied gas or high pressure, toxic and harmful gas. It is relatively difficult. It is difficult to disclaimer and judging the remaining leaks, and must be observed, analyzed and developed by long-term management and maintenance practice.

Characteristics of contained mechanical seal The container mechanical seal is one of many types in mechanical seals, which also have more range of use and characteristics, so in order to facilitate everyone's choice, it will be understood by its related characteristics. The first is to use the "container" concept in the transportation to generate a container seal. This type of sealed rotation and stationary portion are pre-installed as a whole, and the inspection and test are passed back on the shaft shaft in the shaft in the shaft, and the tight screw is fixed to the shaft, and the assembly is removed. Positioning sheets, mechanical seals can be in a parallel surface working condition, put into operation. This is not only easy to assemble but guarantees the quality of assembly. Welding metal bellows mechanical seal is made of contained sealing, which has the above advantages. The card seal is also a container mechanical seal. This seal is contained in the installation ...

Pump mechanical seal repair The pump mechanical seal is a device that is mounted to function in a dynamic sealing operation in a pump apparatus, and avoiding a fluid medium in a water pump splitting through a pump shaft. However, when in use, it is inevitable that there will be fault conditions, so it is important to master the corresponding maintenance method. (L) the seal of the bushing and the shaft; (2) Sealed between the arthrosphere and the bushing;     (3) Moving, static ring seal; (4) Sealing of the static ring and the static ring; (5) Sealed end cap and the pump body. In general, the leakage between the shaft sleeve, the sealing end cap and the pump body is relatively easy to discover and solve, but it is necessary to observe, especially when the working medium is liquefied gas or high pressure, toxic and harmful gas, relatively difficult some. It is difficult to disclaimer and judging the remaining leaks. On the basis of long-term management and maintenanc...

What is reverse osmosis equipment ? Reverse osmosis equipment is a membrane separation technology that uses pressure as the driving force by means of the function of selective permeable (semi-permeable) membranes. When the pressure applied in the system is greater than the osmotic pressure of the influent solution, water molecules continuously permeate The membrane flows into the central pipe through the water production channel, and then flows out of impurities in the water at one end, such as ions, organic matter, bacteria, viruses, etc., which are trapped on the inlet side of the membrane, and then flow out at the outlet end of the concentrated water to achieve the purpose of separation and purification. . The following is about its operation methods and common problems and solutions, the editor of reverse osmosis equipment has done some sorting, for your reference. The reverse osmosis equipment is to pass the raw water through a fine filter, granular activated carbon filter, compr...

Mechanical seals are one of the basic components of precision machines, with a relatively complex structure. They are joint components of various pumps, reactive and synthetic sealing devices, turbo compressors, and submersible electric ideas. The sealing performance and service life of the seals depend on the selection, accuracy and correctness of the installation and use of the machine equipment. The sealing power associated with centrifugal force will also increase. Selection skills: Due to the difference between the working conditions of the mechanical seal and the characteristics of the medium, there are mechanical seals with high temperature resistance, low temperature resistance, high pressure resistance, corrosion resistance, and particle resistance, as well as mechanical seals suitable for easily evaporating light hydrocarbon media. Therefore, it should be based on the application. Choose different structural types and materials for mechanical seals. The important parameters...
