[Three rain valve to recommend the star product - Mechanical seal] Introduction: chemical pump mechanical seal in the important effect of chemical pump mechanical seal is the most common form of FBD-38 seal mechanical seal, but in use because the mechanical seal is damaged the formation of the pump mechanical seal leak is very common, due to the formation of the pump leaked material, energy and spoil FBD-53 machine closures, and even the onset of fire, explosion, poisoning, pollution and other conditions abound. Thus, how the chemical dyeing machinery seal properly use equipment, proper maintenance of the mechanical seal to reduce the leak, avoid pollution, economic progress, the job is an important chemical companies. A mechanical seal mechanical seal structure is mainly composed of ring, stationary ring seals assistant to bomb cartridge mechanical seal elements (or magnetic components) compensation based organizations (such as stretched spring), so ring and shaft together constitute rotation transmission organization. [Three rain valve to recommend the star product - Mechanical seal] Description: From the practical experience, the installation should pay attention to the following aspects. Demand for precision mechanical seal device equipment parts for repeated unit, repair, and lost by the medium corrosion original accuracy or their equipment is old, if these devices without any view, it means mechanical seals, often forming a seal failure FBD-48 mechanical seal, which means there is definitely a need for mechanical seal equipment. Straightness tolerance mechanical seal shaft and the shaft diameter of the seal chamber is 20 ~ 40mm, the tolerance value is 0. 05mm; shaft diameter of 50 ~ 80mm, the tolerance value is 0. 06 ~ 0. 07mm; shaft diameter 80 to 120mm, tolerance is 0. 08mm. Concentricity error and mechanical shaft seal is not greater than 0. 20 ~ 0. 25mm. Radial runout axis radial shaft sealing function will reduce the beating, add the amount of the leak, excessive beating, and even graphite fragmentation. In addition, contact with the shaft seal ring for a long time because of the beating, will appear on the outer groove, thus, there is bound to rule on the shaft runout tolerance. Shaft diameter of 16 ~ 50mm, the runout [0. 04mm; shaft diameter when 55 ~ 120mm, runout [0. 05mm.
