用于试车台的水力测功器循环水压力控制装置

Circulating water pressure control device of hydraulic dynamometer used for test bed

Abstract

本发明公开了一种用于试车台的水力测功器循环水压力控制装置,包括:管道和顺序连接于其上的变频器、液下泵电机、液下泵、安全泄压阀、过滤器、稳压罐、压力变送器、循环水进水开关、测功器、循环水排水开关及测功器本体上的排水阀门,其中,变频器用于将压力变送器检测的压力值与设定的标准值进行对比,并根据对比结果通过液下泵电机调节液下泵的转速改变其输出水流量;排水阀门用于根据所测试发动机功率的改变相应地增大或减小其开度。
The invention discloses a circulating water pressure control device of a hydraulic dynamometer used for a test bed, comprising a pipeline, a frequency converter, a submerged pump motor, a submerged pump, a safety relief valve, a filter, a pressure stabilizing pot, a pressure transmitter, a circulating water inlet switch, a dynamometer and a circulating water drain switch which are connected on thepipeline in sequence, as well as a drain valve arranged on a dynamometer body, wherein the frequency converter is used for comparing the pressure value detected by the pressure transmitter with the set standard value and adjusting the rotation speed of the submerged pump by the submerged pump motor according to the comparison result to change the output water flow; and the drain valve is used forcorrespondingly increasing or reducing the opening degree according to the power change of a tested engine.
