The manual monitoring mode causes labor burden, and is not suitable for liberation of labor force. Excessive addition of lubricating oil increases the waste oil amount of the lubricating oil, easily causes environmental pollution to be aggravated, and increases the economic cost due to the waste of the lubricating oil. Multiple parts such as machine tool equipment, instruments and meters are lubricated, and if each position independently supplies oil, the quantity of oil supply equipment is huge, so that the installation and the use are inconvenient. The oil supply is carried out by adopting one device, the oil supply is carried out through simple oil circuit distribution, the oil pressure and the oil quantity supply are not accurate, the oil quantity and the oil pressure can not be adjusted by the current oil conveying pipeline, and the oil pressure has larger deviation when the oil is conveyed from a main pipeline to a branch pipeline due to different distances, so that the current device requirements can not be met.

When the machine tool is operated, the required lubricating oil amount is found to be more when the machine tool is just started to operate, the required lubricating oil amount is reduced in the middle stage of operation, and lubricating oil is not required to be continuously added when the equipment does not operate. The difference of oil consumption of different equipment is also a great discovery of an oil supply system.
