Abstract

The invention relates to the technical field of filtration of oil products in the hydraulic and lubrication field, in particular to an electronic filter device and method of oil products in the hydraulic and lubrication field. The electronic filter device comprises a pump, a control system, a high-voltage static generator, an electronic filter element device, a high-density fiber water absorption and filtration device, a pressure sensor and a moisture sensor. An oil discharging outlet pipeline of an oil tank is connected with the inlet end of the high-density fiber water absorption and filtration device through the pump, the high-density fiber water absorption and filtration device is connected with the inlet end on the left side of the high-voltage electronic filter element device through a path of an electromagnetic valve. The outlet end on the right side of the high-voltage electronic filter element device is connected with an oil tank inlet pipe of a hydraulic system, and the high-voltage electronic filter element device generates a high-voltage positive and negative electric field. Compared with the prior art, the electronic filter device has the advantages of reducing oil exchanging frequency, achieving recycling economy because the hydraulic oil products can be recycled, reducing equipment faults and the number of maintenance times, prolonging equipment service life, achieving on-line automatic operation and on-line monitoring, reducing pollutant discharge and building environment-friendly equipment.

Description

technical field [0001] The invention relates to the technical field of oil filtration in the field of hydraulic pressure and lubrication, in particular to an electronic filter device and method for oil in the field of hydraulic pressure and lubrication. Background technique [0002] Most of the actions of hydraulic equipment are mainly completed by hydraulic transmission and hydraulic control systems, so it can be said that the hydraulic system is the heart of hydraulic equipment, and it plays a very important role. Both the hydraulic transmission system and the hydraulic control system are completed through the movement of hydraulic oil. The hydraulic oil will be polluted during long-term work, and most of the pollution is inevitable. The main pollutants of hydraulic oil are: moisture, particulate matter, and oxidized sludge. The causes of pollutants are as follows: [0003] 1. Assembly pollution: congenital pollution caused by burrs, sand, metal debris and other particle...
