204 The mechanical seal manufacturer analyzed the causes of the penetration. 1) Leakage caused by pressure. 1. Fault 1: Mechanical seal leakage caused by high pressure and pressure wave. Cause: The specific pressure of the spring and the total specific pressure are too large. When the pressure in the seal cavity exceeds 3MPa, the specific pressure of the seal face will be too large, the liquid film will be difficult to form, the seal face will be severely worn, and the heat generation will increase,

When the mechanical seal manufacturer introduces the ideal sealing machine, it is necessary to understand the leakage first. If the leakage principle is understood, then the corresponding sealing mechanism will be formed. There are three kinds of leakage. One is through leakage, that is, leakage between the sealing surface gaps. The other is leakage, that is, leakage of the sealed fluid through the capillary tube of the seal material. The third is diffusion, that is, under the effect of concentration difference

204 The mechanical seal manufacturer introduces basic knowledge 1. The basic concept of mechanical seal: mechanical seal is a device to prevent fluid leakage, which is composed of at least one pair of end faces perpendicular to the rotation axis, under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, and with the cooperation of auxiliary seals, to keep fit and relatively slide. The auxiliary seal of compensation ring is metal bellows

The mechanical seal manufacturer tells you the precise selection and application of mechanical seals for solid-liquid two-phase flow pumps? Due to the existence of abrasive particle media in solid-liquid two-phase flow, the selection of general mechanical seals often poses the following five hazards: ① Increased wear of seal face. Between sealing surfaces, separated mechanical sealing particles used by the pump leaked into the end face, which played an abrasive role and accelerated the wear of the sealing surface. ② Intermediate
