      煉油裝置用泵

      煉油裝置用離心泵 /Centrifugal Pumps in Petroleum Refinery

      1、  概述

      Introduction

      煉油裝置通常是通過常減壓蒸餾、加氫脫硫、催化裂化、催化重整、延遲焦化、煉廠氣加工及產品精制等裝置,把原油加工成各種石油產品,如各種牌號的汽油、煤油、柴油、潤滑油、溶劑油、蠟、瀝青、石油焦、以及生產各種石油化工基本原料。在煉油裝置中對泵的可靠性要求非常高,使用最多的是懸臂式和兩端支撐式離心泵,占80%左右。

      Petroleum refinery generally consist of sorts of process plants such as atmospheric and vacuum distillation, hydrogenation desulfurization, catalytic cracking, catalytic reforming, delayed coking, gas processing and product refining, and by which crude petroleum is refined to such as various grades of gasoline, kerosene, diesel oil, lubricating oil, solvent oil, wax, asphalt, petroleum coke, as well as the production of basic raw materials of various petrochemical.Pumps serviced in refinery plants are requested to be of high reliability. The widest applications of pumps are over-hung type and between-bearing type centrifugal pumps, and its quantities is almost up to 80% of the total used pumps.
