摘要

目前凝汽器水环式真空泵(水环泵)工作水进口温度(工作水温)往往高于设计值

而且工作水温没有统一的确定方法。在考虑凝汽器变工况、凝汽器汽阻、抽气管道阻力、水环泵工作水汽化的影响和满足凝汽器抽气流量要求的前提下

给出了保证水环泵抽气能力的最大工作水温的确定方法

为水环泵优化运行提供了依据。

Abstract

At present

the temperature of working water in water-ring vacuum pumps is often higher than the designed value

and the said temperature hasn't been unitfiedly determined.Under condition of considering the influence of variable operating condition for the condenser

the steam resistance in condenser

the resistance of air-extracting pipe

and evapouration of working water in water-ring vacuum pump

and under prerequisite of satisfying requirement for ensuring air-extracting capability from the condenser

a method for detemining maximum temperature of working water in the water-ring vacuum pump for keeping vacuum in the condenser has been given

providing with basis for optimizing operation of the water-ring vacuum pumps.
