[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 equipment device for repeated parts of the mechanical seal device, repair, and lost by the medium corrosion original accuracy or their equipment is old FBD-65 mechanical seal, if these devices without any view, it means mechanical seals, often fail to form a 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 mechanical seal, will appear on the outer groove, thus FBD-95 mechanical seal, shaft runout rules have a certain tolerance. Shaft diameter of 16 ~ 50mm, the runout [0. 04mm; shaft diameter when 55 ~ 120mm, runout [0. 05mm. [Three rain valve to recommend the star product - Mechanical seal] Introduction: Device View check to see the type of mechanical seal is not consistent with the needs of FBD-85 mechanical seal, the part is not complete, seal the scale is not appropriate, ring, stationary ring is lubricated flat appearance. Clean with a clean wash oil for mechanical seal parts (except rubber seal outside) clean, then dry, dry note when maintaining the sealing surface, can not scratch, scratch, collision. When determining the amount of tightening means of mechanical seals, start working to clarify the length of stretched spring found the book, and then stretched spring caliper measurement results can be obtained in the free length of the spring is stretched tight capacity, the device should ensure that the amount of stretched spring austerity error [1mm. After viewing the end, according to the exact order of assembly. FBD-60 mechanical seal | Guiyang mechanical seal | FBD selected three rain alloy mechanical seal is provided by Valve Co., Ltd.
