[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 109-43 mechanical seal, if the band sleeve, loose sleeves are not allowed; [three rain valve to recommend the star product - Mechanical seal] Introduction: HQ901 type mechanical seals Minor Outlying mounted, single-end, multi-spring, static, balanced structure, the spring is not in contact with the medium 109-55 mechanical seal, the axial dimension is shorter. Can replace the seal, cartridge mechanical seal design 109-53, simplified installation process, the installation is more simple and convenient. Vice friction materials and auxiliary materials should be selected according to the actual conditions. Scope: Sealed Medium: Oil, water and other liquids. Seal chamber pressure: ≤1.6Mpa sealed chamber temperature: -20 ℃ ~ 160 ℃ line speed: species ≤20m / s seal of many, due to the mechanical seal has less leakage and long life, etc., so that the world today is the mechanical seal In these devices, the main shaft sealing method. Mechanical seals, also known as seal, in the relevant national standards are defined as: "by at least a pair of vertical kept under fluid pressure and compensation mechanism stretch (or magnetic) role and assist with the seal affixed to the end face of the rotation axis of the merger constituted by the relative sliding of the device to prevent fluid leakage. "109-50 mechanical seal, three rain valve (certified), Huaibei 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.
