The invention discloses a liquid pressure stabilizing system. An oil supply unit of the liquid pressure stabilizing system comprises a diaphragm type accumulator, the diaphragm type accumulator is communicated with an oil tank through an oil inlet pipe and an overflowing pipe communication pipe, is communicated with an air source through an air inlet pipe and an air overflowing pipe and outputs pressure oil outwards through an oil outlet pipe, the diaphragm type accumulator is provided with a digital pressure transmitter for detecting internal air pressure; a precision gear pump and an overflowing valve which are driven by a servo motor are arranged on the oil inlet pipe in parallel, a first oil way solenoid valve and a bypass valve are arranged on the overflowing pipe in parallel, the oiloutlet pipe is provided with a second oil way solenoid valve, and a throttle valve and an air way throttle valve are arranged on the air inlet pipe and the air overflowing pipe in series; and a pressure stability control unit which conducts closed loop control over the system and conducts self system pressure regulation is further included. By means of the liquid pressure stabilizing system, theoutput pressure can be flexibly adjusted, and pressure output is stable and accurate through real-time pressure feedback and real-time regulation and control.
Description
technical field [0001] The invention relates to a device for providing stable and adjustable liquid pressure for precision electromagnetic valve measurement, in particular to a liquid pressure stabilizing system. Background technique [0002] However, the current existing processing equipment and production technology cannot guarantee that the produced ultra-high-precision metering solenoid valves are 100% qualified. Therefore, the screening of qualified ultra-high-precision metering solenoid valves is particularly important. [0003] The screening of qualified ultra-high-precision metering solenoid valve products is carried out on a special measuring device. In order to improve the accuracy of detection, it is necessary to supply adjustable and stable pressure liquid to the special measuring device. Contents of the invention [0004] Therefore, the present invention proposes a liquid pressure stabilizing system, the purpose of which is to provide stable and adjustable liq...
