[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, if these devices without any view FBD-90 mechanical seal, 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, will appear on the outer groove, thus, there is bound to rule on the shaft runout tolerance. When the shaft diameter is 16 ~ 50mm FBD-85 mechanical seal, runout [0. 04mm; shaft diameter when 55 ~ 120mm, runout [0. 05mm. [Three rain valve to recommend the star product - Mechanical seal] Introduction: In recent years, production and quality sealing products China gradually entered a new period, a new period. But the mechanical seal, but these are far from satisfactory to carry on various other professional rubber seal products standardization, serialization needs of commodities, especially compared with the advanced countries of the world, whether in product quality Chinese goods kettle mechanical seal is still in terms of types of goods, have a considerable distance. Relative to the huge machinery, the little seal is really humble. Same seal all professional occupations and national production is also unable to enter the career leader in mechanical confused. But the seals on the machinery and equipment of all functions of life and so has a serious impact. In recent years, the production and quality of Chinese seal products gradually enter into a new period, a new period. However, only these are far from satisfactory to carry out all kinds of other professional rubber seal products standardization, serialization needs of commodities, especially compared with the advanced countries of the world, regardless of Chinese goods in the quality of goods is still kind of in the business class, the average There are a considerable distance. FBD-80 mechanical seal, mechanical seal manufacturers selected three rain (certified), Liupanshui mechanical seal is provided by three rain Valve Co., Ltd. of Tianjin. Valve Co., Ltd. Tianjin three rain (www.tjsymf.com) (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. In three rain valve leadership with the staff warmly welcome all inquiries negotiations to create three rain valve a better future.
