Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent oil replacement, and particularly relates to an automatic oil draining and changing device for an oil circuit. Background Art

[0002] Oil plays a significant role in the operation of mechanical equipment. It not only plays a lubricating role to reduce friction, but also has a sealing role to prevent equipment from rusting and cooling. For the oil circuit, the state of the oil is relatively complex and changes over time. Traditional machine pumps are completed by removing the plug to fill or drain the oil. This method has problems such as difficulty in operation and high labor intensity. At the same time, the plug is very small and is easy to fall or lose during operation, causing safety hazards such as blockage of the drain pipe. In the face of a large-volume oil tank, simply replacing the plug still cannot reduce the labor intensity and time of the staff. The replacement process takes too long, and the oil on the inner wall of the oil tank cannot be drained cleanly. Even if new oil is added for flushing, it cannot meet the ideal requirements. In addition, the entire oil change process is prone to leakage, polluting the environment, equipment and clothing. Utility Model Content
