The invention provides a detection and control system of a servo valve temperature screen. The detection and control system includes a hydraulic system and a computer detection and control system; a hydraulic source of the hydraulic system is connected to a servo valve through an oil supply path and an oil return path; the servo valve is connected to a hydraulic cylinder through an oil inlet path and an oil outlet path; a displacement sensor is connected to a piston of the hydraulic cylinder; an input end of a detection element of the computer detection and control system is connected to the hydraulic cylinder, and an output end of the detection element is connected to a working control machine through a conditioning circuit; the working control machine is connected to a volt-ampere amplifier; and the volt-ampere amplifier is connected to a servo valve through a control signal line and a feedback signal line. The detection and control system is simple in structure, and can send detected data to the working control machine through conditioning circuit according to the measured actual working state; the working control machine can analyze and process the detected data and output a signal to the volt-ampere amplifier, automatic control can be achieved, and the working efficiency is improved; dual-working station control can make the system being modularized and make operation convenient; and an analog signal unit can perform direct control on the hydraulic system.
Description
technical field [0001] The invention relates to the technical field of hydraulic equipment, in particular to a measurement and control system for a servo valve temperature screen. Background technique [0002] A servo valve is an advanced, precision hydraulic component that integrates mechanical, electronic and hydraulic technologies. It has the advantages of fast dynamic response, high control precision and high load rigidity, and has been widely used in aviation, aerospace, ships, metallurgy, chemical industry and other fields. However, most of the current systems are only for one kind of work requirements, and cannot flexibly switch hydraulic cylinders to perform different requirements. Similarly, when a certain part of the computer control system has a problem, there is no other control method to keep the equipment running. [0003] Therefore, it is necessary to provide a measurement and control system that can improve the detection efficiency and quality of the servo v...
