[Three rain valve to recommend the star product - Mechanical seal] introduced: (1) determine the scale device: device timing closure, should use manual or sample the goods, to ensure the mechanical seal device scales. (2) Before loading, the shaft (sleeve), gland should be no burr, bearing in good condition; seals, shaft, sealed chamber, gland should be clean and clean. To reduce friction, mechanical shaft seal system parts to be coated with a thin layer of oil H75-110 mechanical seal, for smooth, considering the compatibility H75-170 machine rubber O-ring seal, if not oil H75 -150 mechanical seal can be coated with soap and water. Floating-mounted stationary ring without anti-rotation pin layout, not oiled, should dry loaded gland. Secondary seal; play a secondary seal, the secondary seal ring divided compensation and non-compensation of ring seals. 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: sewage sump pump mechanical seal contrast common sump pump leakage reason. Mechanical seal itself is a high demand for fine parts planning, machining, has a very high quality of the installation requirements. When sewage pump mechanical seal in the use of liquid, you should analyze the use of mechanical seals of various factors of mechanical seals, mechanical seals for a variety of submerged sewage pump skills needs and demand the use of media and there is plenty of smooth conditions, such talent Make sure the sealing work reliably for a long time. 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.
