Abstract

The invention discloses an intelligent control system for a hydraulic pressure test in a cavity. The intelligent control system consists of a distributed control module, a data acquisition module, a pressure-relief control module and a servo system, wherein the distributed control module consists of an analog value input module, an analog value output module, a switching value module and a test control workbench and software; the data acquisition module consists of a pressure sensor and a signal processing module; the pressure control module consists of a low-pressure control module, an exhaust electromagnetic valve and a drainage electromagnetic valve; and the servo system consists of a servo drive, a servo motor and a flow-adjustable plunger metering pump. The system realizes automatic pressurization, pressure maintenance, timing, pressure relief, real-time detection, data acquisition, analysis and processing, real-time analog simulation output of the pressure in a combustion chamber and so on, and improves control precision.

Description

technical field [0001] The invention relates to a water pressure measurement and control system in a chamber, in particular to an intelligent control system for water pressure testing in a chamber, which belongs to the field of test control. Background technique [0002] At present, the pressurization of the hydraulic pressure test in the engine combustion chamber is mainly completed by inching or linkage control of the pressurization pump. The main control scheme is as follows: figure 1 As shown, the main working process is: first turn on the power supply L 1 , L 2 , L 3 , press the start switch SB 2 , contactor KM 1 The circuit is connected, the electric booster pump starts to work, and starts to pressurize the combustion chamber until the pressure indication is reached, then press the stop switch SB 3 , start the switch SB 2 Disconnect, contactor KM 1 The circuit is powered off, and the pressurizing pump stops pressurizing work. If there is a pressure leakage duri...
