Technical Field
[0001] This utility model relates to the technical field of motor valve testing devices, specifically a testing device for a rotary guide hydraulic unit pump motor valve. Background Technology
[0002] The rotary-guided hydraulic unit pump motor valve testing device is a professional testing equipment used to test the comprehensive performance of components such as motors, pumps, and valves in hydraulic units. It is mainly used in fields such as oil drilling and construction machinery. This testing device simulates different working conditions to perform performance tests on key components such as motors, oil pumps, filters, throttle valves, and safety valves in hydraulic units, including the detection of parameters such as flow rate, pressure, and current, in order to evaluate their working status and durability.
[0003] For example, announcement number CN109854569B (titled "Test Device for a Hydraulic Control System of a Rotary Guide Tool") describes a hydraulic control system comprising a motor assembly, a piston pump assembly, and a control valve assembly. The test device includes a test cylinder with a accommodating chamber for fixing the hydraulic control system. The test cylinder also has an oil inlet, an oil return outlet, and a pressure testing port communicating with the accommodating chamber. The pressure testing port is connected to the pressure output port of the hydraulic control system. The oil inlet is connected to an external high-pressure oil source, and the oil return outlet is connected to an external low-pressure oil source. The test cylinder includes a pressure cap, a motor pump sleeve, a valve seat sleeve, and a return sleeve connected in sequence. The motor pump sleeve, the valve seat sleeve, and the return sleeve together form the accommodating chamber. The motor pump sleeve has an oil inlet, the return sleeve has an oil return port, and the valve seat sleeve has a pressure testing port. By setting up a test cylinder, the overall performance indicators of the hydraulic control system can be tested. The internal flow resistance of the hydraulic control system is closer to the actual working condition, and the test results of the hydraulic control system's performance indicators are also closer to the actual working condition, making them more accurate and reliable. This avoids multiple disassemblies and reassemblies of the hydraulic control system and the rotary guide tool, saving time and effort, and increasing testing efficiency. Moreover, the testing device has a simple structure and is easy to use, providing a testing method for the true market application of hydraulic control systems, making it highly practical.
[0004] The aforementioned testing device tests the equipment in the hydraulic system using a test cylinder. However, it is inconvenient to install and fix the motor pump in the test cylinder during the testing process, which affects the testing efficiency of the motor pump in the hydraulic system. Therefore, we provide a rotary guide hydraulic unit pump motor valve testing device. Utility Model Content
