[Three rain valve to recommend the star product - Mechanical seal] Description: Cartridge has the following characteristics: (1) do not need to measure the length of the sealing work to install; (2) the shaft can be adjusted at any time; (3) does not occur When you start the leak problem, because the seal has been pre-tested; (4) installation, simply close the lid bolt kit, easy assembly quality assurance; (5) the protection of the sealing surface before installing or starting or due to contamination from debris operational errors and damage; (6) equipment of thermal expansion can retune; (7) can use with self-centering; (8) easy to remove for cleaning and inspection seal, without disassembling the pump equipment. API682 standard recommended that all mechanical seal with cartridge mechanical seal. [Three rain valve to recommend the star product - Mechanical seal mechanical seal] Technical requirements: a good thermal shock resistance that end 104-85 mechanical seal, require materials with high thermal conductivity and a smaller coefficient of linear expansion 104-65 mechanical seal, and will not crack when subjected to thermal shock. Smaller coefficient of friction sealing ring should match the smaller coefficient of friction. Good self-lubrication in the event of a short work of dry friction 104-80 mechanical seal, do not damage the seal faces. Thus, the sealing ring to have a good self-lubricating, sealing ring material and sealing fluid should have a good wettability. 104-95 mechanical seal, Putian mechanical seal, mechanical seal manufacturers selected by three rain Valve 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!
