[Three rain valve to recommend the star product - Mechanical seal] Description: rubber which is a highly elastic rubber polymers, because it has good flexibility and strength must be sealed tight seal when used, cushioning, shock absorption fine, and has good air tightness, impermeability, wear resistant, corrosion-resistant features. So it is a better seal material 58B-30 mechanical seal in mechanical seal to help seal is drawn up to a selection. In addition to the strengths of the outer rubber ring, because of its elasticity and can in a wide range of Gongyi still adhere to seal not steal 58B-50 mechanical seal, and easy to manufacture. Elected to use a different rubber species, formulation, mixing and curing techniques, various functions can be made to meet the finished product are not the same temperature change in, not the same chemical corrosion and dissolution, swelling and other needs, the rubber seal the disadvantage is that the coefficient of friction circle large 58B-55 mechanical seal, resistance is large stretched spring forward, prone to sticking or aging at high temperatures. [Three rain valve to recommend the star product - Mechanical seal] Introduction: the advantages and disadvantages of various seal: packing offer the cheapest printing chemical mechanical seals, but only the most general use of appropriate conditions and materials; moderate single seal quote GM can use in most conditions; double mechanical seals offer the most expensive mechanical seal, but under severe operating conditions it is necessary to use. 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. 58B-45 mechanical seal mechanical seal manufacturers _ selected three rain (certified) _ Yongzhou mechanical seal is provided by three rain Valve Co., Ltd. of Tianjin.
