[0025] Reference Figure 1-3 The utility model provides a hydraulic pump test device that is convenient for replenishing hydraulic oil, comprising:

[0026] The test unit 100 includes a processing table 101, a fixture 102 is fixedly connected to the middle of the upper surface of the processing table 101, a control panel 103 is fixedly connected to one side of the upper surface of the processing table 101, a storage groove 104 is opened on the outer surface of one side of the processing table 101, a storage component 105 is arranged inside the storage groove 104, an oil pump 106 is fixedly connected to one side of the upper surface of the processing table 101, and the output end of the oil pump 106 is fixedly connected to a delivery pipe 107, a recovery pipe 110 is fixedly connected to the other side of the upper surface of the processing table 101, and a plurality of moving components 111 are arranged on the outer surfaces of the other two sides of the processing table 101. The processing table 101 is the basic platform of the device. The test unit is fixed on the table by the fixture 102 to ensure that all components can remain stable during the test. The fixture 102 can firmly fix the oil pump 106 and the delivery pipe 107 connected to it to avoid vibration or displacement during the test, thereby affecting the test accuracy. Through the cooperation of the oil pump 106, delivery pipe 107, recovery pipe 110 and storage component 105, the replenishment, recovery and storage of hydraulic oil can be efficiently managed, which improves the continuity and efficiency of the test. The storage tank 104 and storage component 105 allow the operator to quickly obtain spare hydraulic oil, saving time in searching and preparing oil.

[0027] The upper ends of both delivery pipe 107 and recovery pipe 110 are fixedly connected to connector 108, and a flow meter 109 is fixedly connected to the outer surface of one side of connector 108. The oil pump 106 is electrically connected to the control panel 103, and the flow meter 109 is electrically connected to the interior of the control panel 103. The moving assembly 111 is also electrically connected to the control panel 103. Through the two-way connection of the delivery pipe 107 and the recovery pipe 110, efficient transmission and recovery of liquid can be achieved. The connector 108 is used to firmly connect the pipeline to ensure that the pipeline is leak-free during operation and improve stability. The flow meter 109 is set on the outer surface of the connector 108. By real-time monitoring of the liquid flow in the pipeline, the flow balance during the delivery and recovery process is ensured to avoid resource waste or equipment damage caused by excessive delivery or excessive recovery. The oil pump 106 is responsible for promoting the flow of liquid. It is electrically connected to the control panel 103 to achieve precise control of the liquid delivery speed and flow through the instructions of the control panel 103. The flow meter 109 feeds back the flow data to the control panel 103, and the control panel 103 makes real-time adjustments according to the set target flow, thereby ensuring stable operation of the system. The mobile component 111 enables the device to be adjusted in position as needed to adapt to different working conditions or location requirements, thereby enhancing the flexibility and applicability of the device.

[0028] Furthermore, storage assembly 105 includes a filter box 105a. The outer surface of filter box 105a is fixedly connected to the interior of storage tank 104. A connector 105b is fixedly connected to the front outer surface of filter box 105a. A transition pipe 105c is fixedly connected to the lower portion of the outer surface of one side of filter box 105a. One end of transition pipe 105c is fixedly connected to storage box 105d. A position sensor 105e is fixedly connected to the interior of storage box 105d. A solenoid valve 112 is fixedly connected to the outer surface of transition pipe 105c. Solenoid valve 112 is electrically connected to the interior of control panel 103. Position sensor 105e is also electrically connected to the interior of control panel 103. The fixed connection between the filter box 105a and the storage tank 104 ensures its stability. The connector 105b allows the fluid to flow smoothly into the filter box 105a. The transition pipe 105c plays the role of fluid transmission, guiding the filtered liquid to the storage box 105d. The solenoid valve 112 installed in the transition pipe 105c sends an electrical signal from the control panel 103 to accurately control the on and off of the fluid, ensuring the accuracy and timeliness of fluid delivery. The liquid storage volume in the storage box 105d is monitored by the position sensor 105e, and the sensor transmits real-time data to the control panel 103. The control panel 103 adjusts the switching state of the solenoid valve 112 according to this information to ensure that the storage volume reaches the predetermined target.

[0029] Furthermore, the moving assembly 111 includes a fixed frame 111a, one side of which is fixedly connected to the outer surface of the processing table 101. The upper portion of the inner wall of the fixed frame 111a is fixedly connected to a mounting frame 111b. A hydraulic cylinder 111c is fixedly connected to the interior of the mounting frame 111b, and the output end of the hydraulic cylinder 111c is fixedly connected to a universal wheel 111d. The extension and retraction of the universal wheel 111d is controlled by the hydraulic cylinder 111c, thereby facilitating the transportation of the equipment. When the equipment needs to be moved, the universal wheel 111d can be pushed out to lift the equipment, and the equipment can be lowered for use, thereby increasing the flexibility of the equipment.

[0030] During use, the hydraulic oil is first placed into the interior of the filter box 105a through the connector 105b, so that the hydraulic oil is filtered to improve the cleanliness level, and then stored. When needed, the oil pump 106 is started to extract it through the delivery pipe 107 for use, and the oil output can be measured by the flow meter 109. The overflowing or circulating hydraulic oil can be recovered through the recovery pipe 110 and enter the interior of the filter box 105a for filtration and utilization, thereby enabling the device to be used in multiple environments, reducing dependence on external devices, and facilitating the use of the device.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
