[Three rain valve to recommend the star product - Mechanical seal] Description: shaft sealing system constitutes the mechanical seal over the shaft sealing costumes are designed for soft packing gland. It is not suitable for holding the mechanical seal 202-50 mechanical seal, not too small, too narrow gap 202-45 mechanical seal, and simple cylindrical shape also inappropriate. At present, foreign countries have been developed to increase the size of the mechanical seal shaft sealing standards. Besides the United States _ Abdullah and British secret Tai Lieke hydrodynamics research group are studying reasonable mechanical seal shaft sealing, its shape should not only be beneficial to the fluid flow and heat dissipate, but also should help to remove solid particles, to resulting in good sealing surroundings. [Three rain valve to recommend the star product - Mechanical seal] Introduction: Reason seal leakage: (1), shaft sleeve sleeve does not extend many leaks sealed box, so to determine the source of the leak is very difficult. Leak bushings are generally stable 202-60 mechanical seal, the sealing surface leakage often increase or decrease. After sealing surface mechanical seal leaks, uneven surface, but sometimes the run to the status quo ante. (Do not rush to overhaul sometimes can be a period of observation to say) (2), if the seal is surrounded by moist, but do not see the leak. This centrifugal force generated when starting operation of the pump so that the leaked liquid back into the sealing surface, since a barrier. And from the flange or connector on the pump leaked liquid drip packing box. (3), to make the thermal expansion in the metal splice member graphite ring loose, it may be due to low temperature so that the O-ring loss of elasticity, resulting in leakage. 202-60 Mechanical seal | 202 mechanical seal selected three rain (certified) | Liupanshui mechanical seal is provided by three rain Valve Co., Ltd. of Tianjin.
