The invention provides a high-precision oil supply system pressure regulating device, including an oil inlet pipeline and an oil return pipeline, the oil inlet pipeline is connected with the oil outlet of the external oil supply system, and the oil inlet pipeline is connected to the oil inlet pressure regulating valve to form an oil inlet pressure regulating system, and then supply fuel to the oil inlet of the consumption device; the oil inlet pipeline is connected to the oil return pipeline through the oil return pressure regulating valve, and the oil return pipeline is connected to the oil return of the fuel consumption device through a three-way pipe respectively Oil return expansion tank, the oil return expansion tank is equipped with a ball valve, when the ball valve on the oil return expansion tank is connected with the oil return pipeline through the tee, the oil return pressure adjustment system is formed. The high-precision oil supply system pressure regulating device described in the present invention can effectively increase the circulation volume of the oil supply system, realize the rapid circulation of the oil supply system and ensure the adjustment of large flow oil consumption through the pressure regulating valves of the oil supply system and the oil return system reliable operation of the device.
Description
technical field [0001] The invention belongs to the technical field of fluid pressure testing systems, and in particular relates to a pressure regulating device for a high-precision oil supply system. Background technique [0002] With the requirements of modern testing technology for the accuracy of data measurement, it is even more necessary to accurately measure the data of the researched system in the process of scientific research and experimentation. Among them, pressure data is the most widely used state parameter in engineering, and its measured value is Accuracy directly affects the accuracy of scientific research and experiments. During the pressure measurement process of the oil supply system, due to the influence of the consumption device on the pressure, the supply system cannot meet its requirements, and the pressure of the oil supply system needs to be adjusted twice. The pressure adjustment device can meet the wide range and high precision pressure adjustment...
