[0002] Hydraulic oil stations are generally electromechanical devices that provide lubrication and power for the operation of machinery in large and medium-sized industrial production. Hydraulic stations, also known as hydraulic pump stations, are mainly composed of hydraulic pumps, drive motors, oil tanks, directional valves, hydraulic valves, throttle valves, relief valves, etc.

[0036] The present application embodiment discloses a hydraulic oil station testing device. Figure 1 The test device includes a test bench 1, a cylinder 2 and a connecting pipe 3. The test bench 1 is fixedly installed on the ground and is located on one side of the hydraulic oil station. The test bench 1 is used as a supporting carrier for the installation of the cylinder 2, and the cylinder 2 is arranged in a vertical direction; a clearance hole 4 is provided on the table top of the test bench 1, and the clearance hole 4 is circular in shape. Of course, in other embodiments, it can also be rectangular or triangular in shape. The clearance hole 4 is used for the piston rod of the cylinder 2 to pass through. The cylinder 2 is connected to the hydraulic oil station through a connecting pipe 3, and the connecting pipe 3 is used to transport oil. Among them, the inner wall of the connecting pipe 3 is coated with an epoxy resin anti-corrosion layer. The epoxy resin anti-corrosion layer has good anti-corrosion ability, which can improve the anti-corrosion ability of the connecting pipe 3, reduce the corrosive effect of oil on the connecting pipe 3, and extend the service life of the connecting pipe 3.
[0037] The hydraulic oil station is connected to the oil cylinder 2 through the connecting pipe 3. The hydraulic oil station supplies oil to the oil cylinder 2, thereby controlling the piston rod of the oil cylinder 2 to perform telescopic movements. The staff can judge whether the hydraulic oil station can operate normally by observing whether the piston rod of the oil cylinder 2 completes the prescribed movement; the entire test process is intuitive and clear, which makes it easy to test the hydraulic oil station and reduces the probability of failure due to pressure problems during the use of the hydraulic oil station.
[0038] Specific, combined Figure 2 , the oil cylinder 2 can be detachably connected to the test bench 1. The upper end of the oil cylinder 2 is fixedly connected to a mounting plate 5, and a plurality of mounting holes are provided on the mounting plate 5, and the mounting holes are spaced apart along the circumference of the mounting plate 5. The mounting plate 5 is locked to the test bench 1 by a fastener 6, and the fastener 6 is a fastening bolt, which passes through the table top of the test bench 1 and is screwed on the mounting plate 5, thereby fixing the mounting plate 5. When the oil cylinder 2 is damaged, the oil cylinder 2 can be removed from the test bench 1 for inspection. As shown in the figure, in this embodiment, two oil cylinders 2 are arranged in parallel, and both oil cylinders 2 can be detachably connected to the test bench 1. Due to the randomness of a single test, errors are easily generated in the test results. By adding two identical oil cylinders 2, the hydraulic oil station is tested together, so as to obtain multiple sets of test data and improve the accuracy of the test results.
[0039] According to some embodiments of the present application, optionally, please refer to Figure 3 . A limit assembly 7 is also installed on the test bench 1, and the limit assembly 7 is used to limit the cylinder body of the oil cylinder 2. The limit assembly 7 includes a first cylinder 71, a first limit plate 72, a second cylinder 73 and a second limit plate 74. The first limit plate 72 and the second limit plate 74 are arranged opposite to each other, and both are used to press on the cylinder body of the oil cylinder 2, so that the oil cylinder 2 is located between the first limit plate 72 and the second limit plate 74. The first cylinder 71 is fixed on the test bench 1 and connected to the first limit plate 72. The first cylinder 71 is used to control the movement of the first limit plate 72; the second cylinder 73 is also fixed on the test bench 1 and connected to the second limit plate 74. The second cylinder 73 is used to control the movement of the second limit plate 74. The first cylinder 71 controls the first limit plate 72 to move in the direction close to the oil cylinder 2, and the second cylinder 73 controls the second limit plate 74 to move in the direction close to the oil cylinder 2, so that the cylinder body of the oil cylinder 2 is clamped by the first limit plate 72 and the second limit plate 74, thereby limiting the position of the oil cylinder 2 and reducing the shaking of the oil cylinder 2.
[0040] In addition, in some embodiments, a measuring ruler 8 is installed on the table of the test bench. The measuring ruler 8 is vertically arranged and has scale lines on its surface, which are arranged along the extension direction of the piston rod of the oil cylinder 2. The measuring ruler 8 can measure the telescopic length of the piston rod of the oil cylinder 2, which is convenient for the staff to quickly and accurately read the telescopic length of the piston rod, further judge whether the performance of the hydraulic oil station is normal, and improve the accuracy of the test results.
[0041] The implementation principle of the hydraulic oil station test device of the embodiment of the present application is as follows: during the test, the staff uses the connecting pipe 3 to connect the hydraulic oil station and the oil cylinder 2 together, and then uses the hydraulic oil station to supply oil to the oil cylinder 2, and controls the piston rod of the oil cylinder 2 to perform telescopic movements. The staff determines whether the hydraulic oil station can operate normally by observing whether the piston rod of the oil cylinder 2 completes the prescribed action; the entire test process is intuitive and clear, which makes it convenient to test the hydraulic oil station and reduces the probability of failure due to pressure problems during the use of the hydraulic oil station.
