大型壓縮機密封技術(shù)應用與研究
[Abstract]:Fluid sealing technology is widely used in the petrochemical industry at present. Most of the medium produced and transported in petrochemical industry has the properties of high temperature and pressure, flammable and explosive, toxic and harmful. Once leaking into the atmosphere, it is not only a waste of material, It causes device parking, brings economic loss to enterprises, and endangers atmospheric environment and personal life safety. Thus, the safety and smooth operation of the seal is extremely important. The study of fluid sealing technology is of great significance to the smooth and effective operation of the pump in petrochemical industry, especially to the smooth operation of large key compressor units. In this paper, according to the problems existing in the sealing process of the rich gas compressor in the catalytic unit and the circulating hydrogen compressor in the heavy oil hydrogenation unit, through the analysis of the disassembly of the seal and the relevant theoretical calculation, The following two aspects have been studied and reformed: (1) the gas-filled labyrinth seal of the rich gas compressor of the catalytic unit has been reformed, and the simple gas-filled labyrinth seal was initially used in the catalytic unit rich gas compressor, and the effect of this set of seals is not good. Six months after the operation of the unit will appear signs of seal leakage, inspection found that the labyrinth seal parts are damaged, so the unit can not according to the requirements of the company to achieve a long period of operation. In this paper, through the research and transformation, the air extraction facilities are added to the original seal to ensure the safe and stable use of the seal. The long period operation of the unit has been realized. (2) aiming at the problems of floating ring seal of circulating hydrogen compressor in heavy oil hydrogenation unit, the static calculation of floating ring seal is carried out on the basis of analyzing the force of floating ring. Find out the factors that affect the failure of floating ring seal. In view of these factors, this paper makes a comparative analysis, finds out the feasible and economic and safety benefit of the revamping method, and carries on the corresponding transformation to the seal. The improved seal has been verified many times and the desired effect has been achieved.
