什么情况会影响机械密封的动作性呢 ? 浆料的堆积会使得弹簧作用受阻、滑动部件动作失控、密封面的表面遭到磨损等，严重影响着机械密封的动作性;当滑动密封面出现磨损、硬化和老化等情况时，轴和轴套会因此而损坏，弹簧座也会磨损甚至弯曲。
Mechanical seal technology relies on a pair or pairs of relatively sliding ends perpendicular to the shaft, which can still maintain the joint under fluid pressure and other force compensation mechanisms, combined with auxiliary seal devices, to achieve leakage stoppage. The FECT mechanical seal keeps the contact ring and the moving ring of the static ring in motion. The aim of the seal is to create a suitable specific pressure between the stationary ring and the moving ring and to maintain a liquid film between them. The main parts used for mechanical seal are static ring and moving ring, and the auxiliary parts are o type, U type and x Type Sealing rings, and the compensation parts include spring, push ring, etc. The driving parts include driving screw and driving pin, and the fastening parts include pushing ring, spring seat, gland and fastening screw, etc. . So what equipment is mechanical seal mostly used in? In general, mechanical seals are used in centrifugal pumps, centrifuges, compressors and reactors and other equipment. The utility model has the advantages of good sealing performance, less leakage, long service life, low energy consumption and no need for frequent maintenance. Mechanical seal is also very good in adaptability, generally can adapt to automated production and high temperature and high pressure and other harsh environment and seal requirements. Seal leakage problems common mechanical seal leakage cases have the following: 1. By the SEAL surface flatness of the damage caused by leakage seal surface damage is mostly caused by uneven slip marks and facial cut marks. The cause may be due to the pump seal box and agitator head deformation or damage, or bolt fastening force is not uniform, resulting in static ring sealing surface deformation, and finally leakage. It is also possible that the change of temperature and the difference of thermal expansion caused the change of seal surface shape. The seal can also be damaged, leading to leakage problems. 2. The lubrication of the leakage end face seal caused by the lubrication damage of the seal face is also very important, in addition to the end face liquid film to seal the role, but also to complete the normal operation of the role of lubrication. Once the end of the liquid film damage, it will cause friction seal surface wear and roughness, and even some hard materials will have cracks and other serious phenomenon. When the temperature of the sliding friction surface rises suddenly, if the heat accumulation can not be removed immediately, it will cause the evaporation of the sealing liquid and the disappearance of the lubricating film, which will lead to the thousand friction phenomenon. Thousand Friction is easy to damage the sealing surface, and buried a large number of potential leakage. 3. The moving ring and the stationary ring of the leaking mechanical seal caused by the action damage are always rotating along with the shaft, and they are always in the same motion frequently and repeatedly. This repetitive motion will not only change the seal face, at the same time, it will increase the axial movement of the device, and gradually reduce the precision of the mechanical seal. In this way, over a long period of time, each component of the device will be damaged or even deformed, and then lose the serviceability, resulting in leakage of the seal. What conditions will affect the mechanical seal of the action? First of all, the accumulation of slurry will make the function of the spring blocked, the movement of the sliding parts out of control, and the surface of the seal face will be worn, which will seriously affect the movement of the mechanical seal, the shaft and sleeve will be damaged, and the spring seat will wear out and even bend. 4. The leakage caused by the superposition of many factors is sometimes caused by the superposition of many factors, such as thousand friction, poor slip, slip ring deformation and flatness deformation, etc. , it could easily cause a leak. Many of these reasons are due to excessive fatigue, uneven pressure and liquid film damage caused by. Therefore, the correct installation and maintenance of mechanical seal cleanliness is very important, coupled with good cooling effect, this can better eliminate hidden dangers.
