Wool felt gasket a wide range of applications
Gasket, is a used machinery, equipment, pipelines as long as there is a place where the fluid is sealed parts, the use of internal and external, sealing material. Seals are made of metal or non-metallic plate material, by cutting, stamping or cutting and other processes made for the sealing connection between the pipe, mechanical equipment and mechanical seal between the mechanical connection. According to the material can be divided into metal gasket and non-metallic gasket.
Gasket seal occupies a very important position in the modern industrial enterprises, the quality of the seal is directly related to the continuous production, property safety, energy saving and environmental protection and people's physical and mental health, so the gasket development more and more people's attention . With the modern industry, especially the modern petroleum, chemical industry, atomic energy industry, the rise of large power plants, pressure vessels to the high temperature, high pressure, high vacuum, cryogenic and large-scale, multi-series direction, gasket gasket constantly put forward new requirements , A variety of new materials, new structures continue to appear, the sealing performance is varied. In addition, the pressure fluctuations, temperature changes, relaxation of bolt preload, flange tilt, misalignment, sealing surface defects, corrosion of the medium will have a significant impact on the sealing effect. Therefore, how to choose the right gasket according to the working condition and how to properly install it is the key to ensure the sealing effect.
Wool felt gaskets are widely used in the static sealing of the joint surfaces of pipes and shells of construction machinery and diesel engines. The elastic deformation of the wool felt seals the unevenness of the joint surface, cut off the leakage channels, increase the leakage resistance, or withstand the pressure difference between the inside and the outside And other ways to prevent the flow medium (gas, cooling water, lubricating oil, gear oil, hydraulic oil, brake fluid, etc.) leakage. Such as the cylinder head of diesel engine, timing gear chamber cover, oil pan, fuel injection pump side cover, intake and exhaust pipe, gearbox cover in construction machinery chassis, direction machine side cover, axle housing back cover, final drive housing, etc. .
