[Three rain valve to recommend the star product - Mechanical seal] Introduction: mechanical seal according to the working conditions and the nature of the different media, there are high temperature, low temperature mechanical seals, high pressure, corrosion-resistant mechanical seals, mechanical seals resistant granular media and adapt easily vaporized light hydrocarbon medium such as mechanical seals, mechanical seals should be selected and a different type of construction material according to different uses. Mechanical seals are widely used in all sectors of business. Water pump plant, printing machinery, paper mills, power plants, chemical plants, pharmaceutical shipyard, and sewage treatment plants, and is widely used in hospitals mechanical seal, agriculture H7N-80 mechanical seal, class cooling equipment, leather industry H7N-100 mechanical seal, heavy machinery. [Three rain valve to recommend the star product - Mechanical seal] Introduction: mechanical seal machine accuracy requirements (to pump mechanical seals, for example) (1) radially mounted mechanical seal parts of the shaft (or sleeve) runout tolerance maximum of 0.04 ~ 0.06mm. (2) axial movement of the rotor is not more than 0.3mm. (3) locating the seal cavity and seal cap combined face-axis (or sleeve) surface does not exceed the maximum runout 0.04 ~ 0.06mm. Unanimously confirmed the seal (1) confirm whether the requirement to install seal model. (2) carefully before installation and assembly diagrams contrast, the number of parts are complete. (3) and the drive coil spring mechanical seal, which spring has left, D points, shall always choose the shaft rotation.
