[Three rain valve to recommend the star product - Mechanical seal] Description: After a Notes installation, be very careful to avoid misalignment installations produced (1) on the gland should be looking for are the couplings bolts should be uniform on the branch, to prevent the end face of the gland seal deflection M74N-40 aircraft, with a feeler points, the error is less than 0.05 mm auxiliary seals;. play a secondary seal, the secondary seal ring divided compensation and non-compensation secondary seal ring. It can be an O-ring, V-ring, wedge ring, rectangular ring, etc., used to seal the shaft seal and mechanical seal, mechanical seal and housing. [Three rain valve to recommend the star product - Mechanical seal] Description: Seal Failure Analysis sealing surface itself would provide evidence of seal failure, such as vibration, there will be signs of wear and tear on the transmission parts, such as traces of not Obviously, it is generally caused by improper assembly. For poor quality graphite ring (ring) is concerned, its large internal porosity, this is because in the manufacturing process, the aggregation caused by the expansion of gases inside the graphite carbon particles blown out, so this low-quality graphite ring seal to enable the mechanical seal, it is easy to fall off the carbon particles M74N-25 mechanical seal, leaving the sealing surface of the seal stuck when disabled. Friction: At the top of the compensation and non-compensation ring ring inlaid with a pair of seal faces, play a major role in sealing machine seal. Under normal circumstances compensate narrow ring of soft material, end; uncompensated ring with a hard material M74N-38 mechanical seal, face wider. Elastic element and locking ring: they constitute the load, compensation and buffering mechanism to ensure that the mechanical seal fitting end face after installation; timely compensation when worn; in by vibration, ran a dampening effect. The elastic member may be a spring, bellows, wave springs and the like. Locking ring for axial and radial positioning of an elastic element, usually both transmission torque or torque to overcome the function. M74N-20 mechanical seal, mechanical seal selection Tianjin rain (certified), Hanzhong 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.
