Hydrostatic system Experimental study on structural improvements

(A) hydrostatic test of a tank nozzle. Hydrostatic tank characteristics and purpose of the pilot study hydrostatic tank is a special tank, which is divided into two chambers (Figure 1). Installed in the lower chamber with a diffuser effect of the injector, using the throttling effect of the injector, the  Hydraulic tube fittings pump, with a certain operating oil back to the oil pressure through a nozzle, the lower high-speed jet nozzle, through the lower diffuser nozzle before entering the pump suction pipe. At this time, high oil pressure energy into kinetic energy. With this special structure of the injector is designed to make free oil into oil pressure pump, which not only improves the ability of self-priming pump, cavitation remove the oil, but also improves the efficiency of the system. In order to select the ideal injector in order to make it work in the oil injector throttle minimum loss, and can get the highest pump inlet pressure, so that the system has the best economic results, we use orthogonal test spray the geometry of the oil tested. For six pairs of nozzles programs were carried out by ten kinds of tests, the test is shown in Table 1. (2) Test results (DD) can be seen from Table 1, the data of nine ideal solution, in the power nozzle diameter 12.5 mm, the diameter of the nozzle must be advised 15 mm spacing of 11.8 mm, the pressure into the oil obtained 3.1 kg force / cm.
