specific Embodiment approach 1
[0011] Specific implementation mode one: combine Figure 1-Figure 7 To illustrate, an experimental device for testing the flow pressure characteristics of the pressure buffer tank of the distribution plate in this embodiment includes a hydraulic pump 11, a first overflow valve 12-1, a second overflow valve 12-2, a first pressure sensor 13-1, First temperature sensor 14-1, second pressure sensor 13-2, second temperature sensor 14-2, throttling device 15, flow sensor 16, throttle valve 17, electromagnetic reversing valve 19, anchor 1 and liquid storage box 18;
[0012] The throttling device 15 includes an adjustment mechanism 2, a tightening mechanism 5, a moving block 6, a buffer tank plate 9 and a bottom block 10, the bottom block 10 is installed on the foot 1; the buffer tank plate 9 is embedded on the bottom block 10 On the surface, the moving block 6 is arranged on the upper surface of the buffer tank plate 9, a buffer tank 9-1 is processed on the upper surface of the buff...
specific Embodiment approach 2
[0017] Specific implementation mode two: combination Figure 4-Figure 7 Note that the buffer grooves in this embodiment are triangular grooves, U-shaped grooves, semicircular grooves or damping holes. With such a setting, the flow and pressure characteristics tests of different buffer tanks are completed through buffer tanks with various structural forms and size parameters, which provides experimental guarantee for the accurate calculation of flow pressure parameters in the plunger pump design process. The damping hole is a blind hole, and the buffer tank plate of this embodiment is provided with a liquid hole 9-2, the liquid hole 9-2 is connected with the channel 10-1, and the outer circumference of the liquid hole 9-2 is processed with a buffer Slot 9-1. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0018] Specific implementation mode three: combination figure 1 Note that the liquid medium in the liquid storage tank 18 in this embodiment is hydraulic oil, kerosene or water. Such a setting can provide experimental guarantee for the design of the plunger pump valve plate with various media and various working temperatures. Others are the same as in the first or second embodiment.
