PT泵试验台可用来模拟PT泵在发动机上的各种实际工况,对PT泵进行有关参数的测试、调整。这就不仅要求试验台测试系统本身具有较高的精度,以便在结构性能上保证达到试验所要求的各项模拟条件,而且要采用较高精度的显示仪表。目前PT泵试验台一般是按“流量计”法进行设计的。即PT泵必须在试验规定的流量下检测各参数是否符合要求,进而对各参数的相应控制装置进行调整。这就要求流量计必须真实地反映PT泵在相应工况下的实际流量。流量计
PT pump test bench can be used to simulate the PT pump in the engine on a variety of actual conditions, the PT pump parameters of the test, adjust. This not only requires the test bed test system itself has high accuracy, in order to ensure that the structural performance of the test to meet the requirements of the simulation conditions, but also to use a more accurate display instrument. At present, PT pump test bench is generally designed according to the “flow meter” method. That is, the PT pump must test whether the parameters meet the requirements of the test flow rate, and then adjust the corresponding control device of each parameter. This requires that the flowmeter must truly reflect the actual flow of the PT pump under the corresponding conditions. Flowmeter
