Abstract

According to the oil cleaning and detecting system controlled by the electromagnetic reversing valve and the detecting method, pollutants with small particles in oil can be effectively removed after the system and the detecting method are adopted, and the number, the pressure, the temperature and the flow of the polluted particles of the oil, the operation state and parameters of a variable frequency motor and the on-off state of the electromagnetic reversing valve are monitored in real time. According to cleaning of different oil liquids, the operation frequency of the variable frequency motor is set through the human-computer interface, control over the oil liquid pressure and flow is achieved, and the system reaches the optimal cleaning state. The system further has the functions of fault sound-light alarm, fault display and record, fault reset and sudden stop, on the premise that safe operation of equipment is guaranteed, the functions of oil cleaning, system oil inlet detection and system oil outlet detection are achieved at the same time through reversing switching and combined control of different electromagnetic valves, and the safety of the equipment is guaranteed. The problem that cleaning, detection and cleanliness monitoring of small impurity particles in oil are carried out at the same time is solved, and the method is simple and easy to operate.

Description

technical field [0001] The invention belongs to the field of hydraulic detection and control, and relates to a hydraulic system and a detection method for controlling the cleaning of oil by an electromagnetic reversing valve and detecting the cleanliness of oil after cleaning. It is suitable for cleaning polluted oil with small impurity particles and testing the cleanliness of oil after cleaning. Background technique [0002] As we all know, hydraulic transmission systems are commonplace in industrial production and our living equipment. Most of the failures in the hydraulic transmission system are caused by impurities mixed in the oil. The contaminants in the oil often cause wear on the joint surface of the moving pair of the hydraulic components or block the moving parts, block valve ports, and corrode components. , resulting in greatly reduced reliability of the hydraulic system. The gap between the hydraulic components and the moving surface is mostly in the range of 1...
