捷克斯洛伐克制造的NC104试验台(图1)是一种新型“Moтoрпaл”试验台,按其布置来说,是NC101型的改进型。这种NC104试验台结构能够检验和调节各种PV燃料泵,采用专用夹具也能检验和调节其它种燃料泵。试验台装有液力传动装置,可保证交变负荷时工作的均衡性,这一点在检验调节器的工作时非常重要。此外还具有自动的行程计数器。测量装置是在下面填加燃料,借助剩余压力调节供给燃料的开始时间,能保证更精确地进行测量。为了迅速测定供给燃料的实际开始时间,而使用一种电子闪光仪,它是测
The NC104 test bench made in Czechoslovakia (Fig. 1) is a new “Moтoрпaл” test stand which, in its layout, is an improved version of the NC101. This NC104 test bed structure is capable of inspecting and adjusting various PV fuel pumps and using special fixtures to inspect and adjust other types of fuel pumps. The test rig is equipped with a hydrodynamic drive to ensure a balanced work load at alternating loads, which is important when checking the operation of the regulator. In addition it has an automatic travel counter. The measuring device is filled with fuel underneath, with the remaining pressure regulating the start of the fuel supply, which ensures more accurate measurements. In order to rapidly determine the actual start time of the fuel supplied, an electronic flash meter is used
