Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline simulation devices, and more specifically, relates to a multi-pipeline simulation device for hydraulic pressure. Background Art

[0002] In the hydraulic system, the pipelines are intricate, and the normal operation of the hydraulic system is finally achieved through the interconnection between the pipelines. In the design process of the hydraulic system, it is necessary to test the multi-condition performance of the hydraulic pipeline system, such as testing the performance of pipelines of various specifications at different temperatures and loads. In CN201910049101.0, a multi-condition performance test device and system for a hydraulic pipeline system discloses a multi-condition performance test device including a fixed block, multiple groups of pipeline connection joints and a heater. The fixed block is provided with multiple first mounting holes and multiple second mounting holes that are interconnected, and the multiple first mounting holes are connected to the multiple second mounting holes; each pipeline connection joint is installed in the first mounting hole one by one, and the size specifications of the multiple groups of pipeline connection joints are different; the heater is installed in the second mounting hole. The multi-condition performance test device can test pipelines of various specifications at the same time; it can simulate the temperature environment when the oil moves violently, and can test other performances of the pipeline under the condition of applying temperature load, and the test of the pipeline is more in line with the actual operating state of the pipeline. Although the device simulates the performance detection under temperature load, it does not consider the problems that may exist between the pipeline connections of different structures.

[0003] In order to avoid accidents after the hydraulic system is installed, it is necessary to conduct a simulation test on the hydraulic pipeline first. During the test, different pipeline paths are selected to simulate various situations and possible problems are checked and solved. At present, conventional simulation test devices are tested directly through pipeline connections. If different situations need to be simulated, the pipeline needs to be replaced and different paths need to be disassembled and tested. The simulation takes a long time and is inefficient.

[0007] Furthermore, one end of the first simulation tube and the second simulation tube passing through the box body is equipped with a tube connector for connecting the connecting tube, and the end of each first simulation tube and the second simulation tube near the tube connector is equipped with a pressure sensor.

[0008] Furthermore, the angle between the first simulated tube (5) and the second simulated tube (6) is 30°, 45°, 60° or 90°.

[0009] Furthermore, a flow sensor and a temperature sensor are installed at the connection point between the first simulation tube and the second simulation tube.

[0010] Furthermore, the first simulation tube and the second simulation tube are both made of transparent material, which facilitates the replacement or maintenance of the first simulation tube, the second simulation tube, the solenoid valve, etc. inside the box, and the flow of the hydraulic oil in the first simulation tube and the second simulation tube can be intuitively seen, which further improves the effectiveness of the pipeline simulation test to a certain extent.

[0011] Furthermore, a detachable transparent plate is installed on the upper surface of the box.

[0012] Furthermore, two elastic rods are fixed on the surface of the transparent plate in contact with the box, with a certain gap between the two rods. A through hole for the rods to pass through is opened on the box, and a limit block for limiting the movement of the rods is fixed at one end of the rods located in the box.
