[Three rain valve to recommend the star product - Mechanical seal] Description: crack graphite ring (ring) is due to vibration, stress rubber ring up big and graphite ring itself caused transmission parts, and coke is is caused due to high temperature, which is common in high-temperature hot oil refinery medium. Secondary seal; play a supporting role in sealing M74N-110 mechanical seal, the secondary seal ring divided compensation and non-compensation of ring seals. It can be an O-ring, V-ring, wedge ring, rectangular ring, etc. M74N-75 mechanical seal for sealing the shaft seal and mechanical seal, mechanical seal and housing. Transmission: transmitting torque from the role. Common Transmission has drive units, forks, pins, key or spring and turns. [Three rain valve to recommend the star product - Mechanical seal] Description: synthetic rubber ring big swell mostly due to chemical erosion caused by mechanical seal, they all have some of their own characteristics, such as fluorine rubber resistant to high temperatures, and ethylene , propylene ○-ring used in the petroleum oil will swell, ozone NBR aggressive action, so do not install nitrile rubber in the motor M74N-85 mechanical seal, so the temperature and chemical corrosion is usually caused by rubber products sclerosis, mainly crack. 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. M74N-100 mechanical seal, mechanical seal Florida, M74N mechanical seal manufacturers selected three rain provided by Valve Co., Ltd. Tianjin three rain. Valve Co., Ltd. Tianjin three rain (www.tjsymf.com) strong, credible, in Tianjin seal industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the three rain valve into the brilliant and you work for a better future!
