Abstract

The invention discloses a hydraulic element detection system based on a PLC (programmable logic controller). The hydraulic element detection system comprises a flow meter, a thermometer and a pressure gauge for respectively testing a flow rate parameter, a temperature parameter and a pressure parameter of a detected hydraulic element in a tested hydraulic system as well as a PLC which is used for receiving the signals outputted by the flow meter, the thermometer and the pressure gauge and controlling a frequency converter which is connected with a three-phase asynchronous motor, wherein the input end of the PLC is connected with the flow meter, the thermometer and the pressure meter, the output end of the PLC is connected with an alternating-current contactor, and the alternating-current contactor is connected with the three-phase asynchronous motor; the PLC is connected with a principal computer, the input end of the principal computer is connected with a human-computer interface, and the output end of the principal computer is connected with a printer. The hydraulic element detection system can be used for detecting different hydraulic elements under different road conditions and is high in detection precision, high in work reliability, low in realization cost, high in function flexibility, low in power consumption, low in failure rate and adjustable in function.

Description

technical field [0001] The invention relates to a detection system, in particular to a hydraulic component detection system based on a PLC controller. Background technique [0002] At present, the known way to detect the performance of hydraulic components is to use common methods such as ordinary pressure gauges and thermometers. When the hydraulic components are in working condition on the construction machinery, the data changes are monitored in real time through external pressure gauges and other instruments, and the quality of the hydraulic components is used as the basis for judging whether the data changes conform to the theoretical data. However, this method has a narrow scope of application and is only suitable for component testing in working conditions, not suitable for monitoring hydraulic components after maintenance or in an unknown state, and cannot systematically save and record test data, which cannot meet the requirements of actual use requirements. Cont...
