TEST STUDY ON INTERLOCK AND SWITCH OVER OF FUEL-OIL PUMP
摘要
燃油泵变频启动初期油泵出力低
难以维持燃油系统压力。对此
通过燃油泵变频和工频联锁切换比较试验
对切泵过程中燃油压力变化进行对比分析
结果表明
燃油泵采用变频切换方式会导致燃油系统跳闸
而采用工频切换方式则可避免此类问题发生。
Abstract
In the initial stage of frequency conversion to start the fuel-oil pump
the output capacity of said pump has been lowered
being difficult to maitain the pressure in fuel oil system.For this
the pressure variation of fuel oil in the process of switching the pump over has been compared and analysed through comparison test of interlock and switch over under frequency conversion and power frequency of the fuel oil pump.Results show that the switch over mode adopted by the fuel oil pump under frequency conversion can lead the fuel oil system to trip
but the switch over mode under power frequency can avoid the fuel oil system to trip.
