On the hydraulic machines of the sealing member and the classification introduced

Today Xiaobian to discuss the role of the seals in the hydraulic machines hydraulic system and what, you know? Here we take is that the knowledge in this regard. The role of the sealing member to prevent leakage of the inside and outside of the working medium, as well as the hydraulic system of the hydraulic machines to prevent the invasion of foreign matter such as dust, metal shavings, can achieve the sealing apparatus, wherein the sealing action of the key element is referred to a seal member. The seal is divided into a gap sealing and non-gap seals, the former must be guaranteed with the gap, and the latter is the use of the deformation of the seal member to completely eliminate the gap of the two mating surfaces so that the gap control in the need to seal the liquid can pass below the minimum gap ; minimum gap is determined by the pressure, the viscosity of the working medium, the working temperature, the mating surfaces relative movement speed, etc.. The sealing device in the hydraulic system of hydraulic machines in various forms, such as piston ring seal, mechanical seal, a combination of gaskets, metal gaskets, rubber gaskets, rubber seals, etc.. In general, the main requirements of the hydraulic machines hydraulic system seals: 1 in a certain pressure and temperature in the range having a good sealing performance; 2 when there is relative movement together by seal friction should be as small as possible, the friction coefficient should be stable; Corrosion resistance, wear resistance, not aging, long working life, the wear and tear can automatically compensate to some extent; Simple structure, easy assembly and disassembly, and low cost.
