[Three rain valve to recommend the star product - Mechanical seal] Description: Preparation before starting a comprehensive inspection of mechanical seals mechanical seal, and ancillary equipment and pipeline installation is complete, whether compliance with the technical requirements. 2, before the mechanical seal startup hydrostatic test, check the mechanical seal leaks. If more 112-90 mechanical seal leakage should try to find out the reason for cancellation. If still valid, you should check the disassembly and re-install. General hydrostatic test pressure for 2 to 3 kg / cm. 3, according to jigger 112-80 rotary pump mechanical seal, check whether the light evenly. Such as a disk drive difficult or not moving, you should check whether the size of the error assembling, installation is reasonable. [Three rain valve to recommend the star product - Mechanical seal] Introduction: HQ901 type mechanical seals belong externally mounted, single-end, multi-spring, static, balanced structure, the spring is not in contact with the media, a shorter axial dimension. 112-65 can replace oil seal mechanical seal, container design, 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 prevent fluid leakage relative sliding device constituted. "112-100 mechanical seal, mechanical seal manufacturers 112 selected three rain (certified), Ya'an 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.
