炼油装置用离心泵

Centrifugal Pumps in Petroleum Refinery

1、  概述

Introduction

炼油装置通常是通过常减压蒸馏、加氢脱硫、催化裂化、催化重整、延迟焦化、炼厂气加工及产品精制等装置，把原油加工成各种石油产品，如各种牌号的汽油、煤油、柴油、润滑油、溶剂油、蜡、沥青、石油焦、以及生产各种石油化工基本原料。在炼油装置中对泵的可靠性要求非常高，使用**多的是悬臂式和两端支撑式离心泵，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.
