[0006] To achieve the above purpose, the present utility model provides the following technical solutions:

[0007] A performance testing device for high - pressure large - flow pumps includes a workbench. A slide plate is slidably arranged on the upper surface of the workbench. A pump body is fixedly connected to the side wall of the slide plate. A support frame is fixedly connected to the upper surface of the workbench. A pipe body is fixedly connected to the inner wall of the support frame. A corrugated hose is fixedly connected at the gap between the pipe body and the pump body.

A test plate is movably sleeved on the rod wall of the fixing rod. An indicating rod is fixedly connected to the side wall of the test plate.

[0008] Preferably, a fixing plate is fixedly connected to the top end of the workbench. Two metal elastic rods are fixedly connected at the gap between the fixing plate and the slide plate. The two metal elastic rods are arranged cross -wise, which can exert a reaction thrust on the slide plate when the slide plate moves, ensuring the test effect and facilitating subsequent resetting.

[0009] Preferably, a guiding block is fixedly connected to the bottom of the slide plate. A guiding groove is opened on the inner wall of the top end of the workbench. The guiding block is slidably arranged on the inner wall of the workbench in the guiding groove, which can improve the stability of the movement of the guiding block.

[0010] Preferably, an indicating needle is fixedly connected to the side wall of the sliding plate, and a plurality of scale bars are provided on the side wall of the workbench. The indicating needle is slidably arranged on the side walls of the plurality of scale bars, so that the moving position of the sliding plate can be observed in time.

[0011] Preferably, a baffle is fixedly connected to the inner wall of the test box. A torsion spring is movably sleeved on the rod wall of the fixed rod. One end of the torsion spring is fixedly connected to the side wall of the test plate, and the other end of the torsion spring is fixedly connected to the inner wall of the baffle.

[0012] Preferably, the rod wall of the indicating rod is an arc-shaped rod. An opening is formed in the inner wall of the baffle. The indicating rod passes through the opening and extends above the baffle and is fixedly connected with an extension plate.

[0013] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0014] 1. In the present utility model, when the water flow passes through the test plate, it will squeeze the test plate to rotate along the rod wall of the fixed rod and push the indicating rod to extend above the baffle, so that the water flow rate and water pressure inside the pipe body can be observed. The extension plate can limit the indicating rod.

[0015] 2. In the present utility model, the pump body is fixedly arranged on the side wall of the sliding plate. The pump body is turned on to work. Under the reaction force of the water flow impact, the petals will slide along the inner wall of the guide groove through the guide block, so that the metal elastic rod can be bent and compressed. The reaction thrust received by the pump body during use can be observed and calculated through the position of the indicating needle on the scale bar, and the hose and the pipe body can stably output the water flowing out of the pump body for subsequent recording of the water flow rate.

[0016] 3. In the present utility model, the torsion spring can timely reset the test plate when it is not under pressure, which can ensure the continuous stability of the water flow test. The indicating rod is set as an arc-shaped rod, and the center of the circle is on the same straight line as the fixed rod, so that the indicating rod and the test plate can swing stably and synchronously along the rod wall of the fixed rod.

[0025] A fixed plate 7 is fixedly connected to the top end of the workbench 1. Two metal elastic rods 8 are fixedly connected at the gap between the fixed plate 7 and the slide plate 2. The two metal elastic rods 8 are arranged crosswise. A guide block 9 is fixedly connected to the bottom of the slide plate 2. A guide groove is opened on the inner wall of the top end of the workbench 1. The guide block 9 is slidably arranged on the inner wall of the workbench 1 located in the guide groove

[0026] A pointer 10 is fixedly connected to the side wall of the slide plate 2. A plurality of scale bars 11 are arranged on the side wall of the workbench 1. The pointer 10 is slidably arranged on the side wall of the plurality of scale bars 11

[0027] During use, by fixedly arranging the pump body 3 on the side wall of the slide plate 2 and connecting the pump body 3 to make the pump work, under the reaction force of the water flow impact, the slide plate 2 can slide along the inner wall of the guide groove through the guide block 9, which can bend and compress the metal elastic rod 8. The reaction thrust received by the pump body 3 during use can be observed and calculated through the position of the pointer 10 on the scale bar 11. The hose 6 and the pipe body 5 can stably output the water flowing out of the pump body 3, which is convenient for subsequent recording of the water flow

[0028] When the water flow passes through the test plate 14, it will squeeze the test plate 14 to rotate along the rod wall of the fixed rod 13, pushing the indicating rod 17 to extend above the baffle 16, so that the water flow rate and water pressure inside the pipe body 5 can be observed. The extension plate 18 can limit the position of the indicating rod 17.

[0029] To ensure the continuous stability of the water flow test, as Figures 1-3 shown, the inner wall of the test box 12 is fixedly connected with a baffle 16. A torsion spring 15 is movably sleeved on the rod wall of the fixed rod 13. One end of the torsion spring 15 is fixedly connected to the side wall of the test plate 14, and the other end of the torsion spring 15 is fixedly connected to the inner wall of the baffle 16. The rod wall of the indicating rod 17 is set as an arc rod. An opening is formed in the inner wall of the baffle 16. The indicating rod 17 passes through the opening and extends above the baffle 16 and is fixedly connected with an extension plate 18.

[0030] The torsion spring 15 can enable the test plate 14 to reset in time when not under pressure, which can ensure the continuous stability of the water flow test. The indicating rod 17 is set as an arc rod with its center of the circle on the same straight line as the fixed rod 13, which can enable the indicating rod 17 and the test plate 14 to swing stably and synchronously along the rod wall of the fixed rod 13. Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention.
