[Three rain valve to recommend the star product - Mechanical seal] Introduction: Device View check to see the type of mechanical seals and demand is not consistent, parts are not complete, seal the scale is not appropriate M74N-90 mechanical seal, ring, stationary ring is lubricated flat appearance. Clean with a clean wash oil for mechanical seal parts (except rubber seal outside) clean, then dry, dry note when maintaining the sealing surface, can not scratch, scratch, collision. Tightening means for determining the amount of mechanical seals when M74N-70 machine closures, start working to clarify the length of stretched spring found the book, and then stretched spring caliper measurement results can be obtained in the free length of the spring is stretched tight mechanical seal quantity, unit should ensure that the amount of stretched spring austerity error [1mm. After viewing the end, according to the exact order of assembly. [Three rain valve to recommend the star product - Mechanical seal] Description: According to the above planned hospital observation incomplete statistics, over year to about 30 thermal power plant project, 40 to 50 substation projects selected VRLA batteries, Large department has put into operation. Accounting for about 10% in new thermal power plant project, the substation project up to about 20%, especially in Guangdong, Hunan, Henan and other places, the choice of a higher proportion of VRLA batteries engineering, substations up to about 50% . When the original use of VRLA batteries fewer northwest and southwest regions cartridge mechanical seal, and now some of the power plants under construction VRLA batteries are also accepted in some recent international tender for thermal power plants as required by the tender, the bidders are also abroad VRLA batteries to tender. Other M74N-65 mechanical seal, some seventy years, eighties thermal power plant put into operation, when the original battery when you need to exchange scrapped, there are commensurate with the number of target plant exchange for VRLA batteries, VRLA batteries makes accepted thermal power plant the proportion is rising year by year trend. M74N-90 mechanical seal, mechanical seal selection Tianjin rain (certified), Chizhou mechanical seal is provided by three rain Valve Co., Ltd. of Tianjin. Valve Co., Ltd. Tianjin three rain (www.tjsymf.com) (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.
