摘要

电动给水泵(电泵)是电厂主要的耗能设备。为了降低厂用电率及投资

某些设计提出了取消电泵的方案

形成了无电泵的发电机组。以某电厂使用2号机组电泵为3号机组供水的试运行为例

研究了无电泵发电机组利用相邻机组电泵供水方法的可行性。试运行结果表明

在2号机组运行不受影响的情况下

3号机组试运行工期比正常提前了40多天。

Abstract

Motor-driven feed-water pump is the largest energy-comsuming equipment in power plants.In order to reduce the service-power consumption rate and capital investment

the motor-driven feed-water pump has been cancelled in some design schemes

resulting in power generating unit without motor-driven feed-water pump.Taking trial operation process in one power plant for supplying feed-water to unti no.3 by using the motor-driven feed-water pump of unit no.2 as an example

the feasibility of using the motor-driven feed-water pump of a neighbouring unit to supply feed-water to a unit without said feed-water pump has been studied.The trial operation shows that the trial operation time of unit no.3 has moved up more than 40 days as in convintonal case under condition of the operation of unit no.2 being not affected.
