[Three rain valve to recommend the star product - Mechanical seal] Introduction: principles outlined by a pair of mechanical seal is cartridge mechanical seal or several vertical axis relative to the end face of elastic sliding in fluid pressure and compensation mechanism ( under or magnetic) merged with the role of maintaining the secondary seal affixed to achieve the seal device leakage resistance. Commonly used by mechanical seal stationary ring (stationary ring) a rotating ring (ring) 2, the elastic element 3, spring seat 4, 5 set screws, rotating ring secondary seal 6, 8 and stationary ring seals and other auxiliary elements composition, anti-rotation pin 7 is fixed on a stationary ring gland 9 to prevent rotation. Rotating ring and stationary ring often also based on whether they have the ability to compensate axial ring and called compensation or compensation ring. [Three rain valve to recommend the star product - Mechanical seal] Introduction: Reason seal failure analysis: rubber ring failure and usage patterns, usually a high-pressure compression molding of reasons ○-ring failure, when found ○ hardens into a rectangle or ring type when you need to adjust the amount of compression 104-30 mechanical seal, otherwise it will heat up. It is necessary to understand the use of a synthetic rubber temperature. Synthetic rubber ring big swell mostly due to chemical erosion caused 104-50 mechanical seal, they all have their own characteristics 104-55 some mechanical seal, such as high temperature resistant Viton mechanical seal, and ethylene, propylene ○-ring in the oil Lubricants used will swell, ozone NBR aggressive action, so do not install nitrile rubber in the motor, so the high temperature and chemical corrosion is usually caused by hardening of rubber products, the main reason for the crack. When installing rubber parts are surface nicks and cuts, but also a common cause of seal failure. The signs of the old fixed screw shaft, keyway, spline shaft, sharp shoulder so will damage rubber parts. 104-30 mechanical seal, mechanical seal manufacturers selected three rain (certified), Jiangxi mechanical seal is provided by three rain Valve Co., Ltd. of Tianjin. Valve Co., Ltd. Tianjin three rain (www.tjsymf.com) is a leader in Tianjin, seals, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In three rain valve leadership with the staff warmly welcome all inquiries negotiations to create three rain valve a better future.
