[Three rain valve to recommend the star product - Mechanical seal] Introduction: Generally, there are so few sealing method - 1. sealing parts to minimize congestion and isolation 2. 3. 4. Increase leads or inject leak resistance 5 One additional element acting in the channel 6. A variety of sealing method combinations [three rain valve to recommend the star product - Mechanical seal] Description: synthetic rubber ring is mostly due to the large swell caused by chemical attack, they all have some of each characteristics, such as high temperature resistant Viton mechanical seal, and ethylene, propylene ○-rings used in petroleum oil will swell, ozone NBR has erosion M74F-35 mechanical seal, so do not install nitrile rubber in the motor M74F-43 mechanical seal, so the high temperature and chemical corrosion is usually the main cause of rubber hardening cracks. By at least one axis of rotation perpendicular to the face of the fluid under pressure and the elastic compensating means (or magnetic) effects and secondary seal with the relative sliding holding stick combined to constitute the means to prevent fluid leakage, commonly used in pumps, compressors, the reaction stirred tank, etc. rotary fluid machinery, but also for a gear box, valves, rotary joint, stern shaft seal. Therefore, the mechanical seal is a universal shaft sealing device. M74F-28 mechanical seal, mechanical seal selected three rain (certified), Yiyang 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.
