[Three rain valve to recommend the star product - Mechanical seal] Description: When installing the technical requirements of the mechanical seal is part of high precision mechanical components, has a big influence on the correct installation and operation of its service life. We generally in accordance with the Ministry of Petroleum and Chemical standards. Installation of the mechanical seal of the pump and the mechanical seal with the technical requirements of the following portions: 1, shaft bending degree: maximum of not more than 0.05 mm; 2, rotor runout: near the sleeve at the seal ring is not more than 0.06 mm; 3, shaft axial runout must not exceed ± 0.5 毫米 109-58 mechanical seal, if the band sleeve, loose sleeves are not allowed; [three rain valve to recommend the star product - Mechanical seal]: 1, the installation Removal mechanical seal mechanical seal when carefully 109-43, prohibited the use of hand-hammer and flat shovel, so as not to damage the sealing elements. If less than the time scale demolition, should be cleaned before the demolition. 2, if both ends of the pump mechanical seals, mechanical seal assembly, disassembly process to take care of each other, to prevent a loss. 3, 109-53 run-off mechanical seal mechanical seal, where there is loose gland seal moves the case, static ring parts must be replaced, should continue to be used to re-tighten. Because friction original tracks changes will happen after running loose, sealing contact surfaces easily damaged. 109-58 mechanical seal, mechanical seal Chaohu, three rain valve 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!
