[Abstract]:With the development of science and technology, the requirement of hydraulic cylinder performance is higher and higher. The degree of intelligence is not high, and the backwardness of the hydraulic cylinder test and measurement and control technology seriously restricts the production quality of the hydraulic cylinder in our country. Therefore, we urgently need to design more perfect hydraulic cylinder test. This paper introduces the principle and system composition of hydraulic cylinder type test, studies and analyzes its important measurement and control characteristics, and summarizes the development status of hydraulic cylinder, and improves the production technology level of hydraulic cylinder and the performance of hydraulic cylinder, introduces the principle and system composition of hydraulic cylinder type test, and analyzes its important measurement and control characteristics. The research significance of the hydraulic cylinder test and the content of the test stipulated by the national standard, etc. The key technologies of the hydraulic cylinder type test, such as internal leakage measurement, load efficiency measurement, starting pressure measurement and so on, are designed. The test can be used to detect the performance of hydraulic cylinder, and many tests can be carried out synchronously, which can realize remote stepless voltage regulation, compound speed regulation, proportional loading, etc. Automatic intelligent control of system test. According to the key technical problems of internal leakage measurement, load efficiency measurement and starting pressure measurement in hydraulic cylinder test, combined with the actual situation, A high precision detection system is designed. The temperature calibration method is used to measure internal leakage, which can be measured online in real time and has a very high detection accuracy, and for load efficiency measurement, the proportional relief valve is used to adjust the pressure. Laser measuring instrument monitors piston rod displacement, can be accurately measured and plotted on line. For starting pressure measurement, throttle valve and small range pressure gauge are used to accurately measure starting pressure on line. The test results show that the testing technology is stable, reliable, accurate and efficient, and greatly improves the production efficiency, which provides a reliable basis for the improvement of the production technology level of hydraulic cylinder. It is of great significance to the production and inspection of hydraulic cylinder.
