The low-pressure side adopts a rectangular ring, which is intended to reduce the friction force of the floating ring, improve the sealing effect of the end face, reduce the leakage point of the low-pressure side seal, and simultaneously increase the gap of the floating ring here, while sealing the oil pressure in the stable cavity, The oil is smoothly discharged along the gap. From the working conditions, the working conditions of the high-pressure side floating ring are relatively bad, and the pressure difference between the two sides of the floating ring is small, so the oil leakage on the high-pressure side is much smaller than that on the low-pressure side, generally twice as much. A large amount of heat cannot be taken away by the oil, causing the temperature of the floating ring and the shaft to rise, which easily causes the phenomenon of holding the shaft and the floating ring to be damaged. At present, the synthesis gas compressor feed gas compressor cracking gas compressor propylene compressor and the like all adopt this type of structure to enhance the cooling effect of the floating ring. In order to strengthen the cooling of the high-pressure ring, radial trenches and other measures can also be applied to the development and development of a chemical equipment technology on the high-pressure ring. In order to improve the wear resistance of the shaft at the seal, the bushing is generally added, and a layer of wear-resistant material is applied to the bushing. For example, the seal sleeve of the compressor designed and manufactured by Mitsubishi Heavy Industries Co., Ltd., which is designed and manufactured by Hitachi, Ltd., is sprayed. A layer of chromium-boron compound The sealing sleeve of the syngas compressor designed and manufactured by Clarke Company of America uses the sealing sleeve of the cemented carbide gas compressor to adopt the nitriding method, etc., which improves the wear resistance of the shaft at the seal. Improve the operational reliability of the floating ring. Calculation and static seal test chart Floating ring floating ring seal with radial groove in the design and manufacturing process, will focus on the problem of oil leakage, the amount of oil leakage mainly assess the amount of oil leakage inside the seal ring. If the oil leakage is too much, it will increase the load on the oil pump and the disposal cost of the recovered oil, and even leak into the inside of the cylinder. If the amount of oil leakage is too small, a large amount of heat can not be taken away by the oil, which will increase the temperature of the ring and the oil, and it is easy to cause the suspension shaft to damage the floating ring.
