Problems solved by technology

[0003] The purpose of the present invention is to solve the technical problems that the oil circuit needs to be disassembled and cleaned every time the oil is changed, the operation is complicated, and the cleaning is not thorough. The oil circuit of the equipment is in a clean state, which completely solves the problem of secondary pollution caused by the oil circuit. The operation is relatively convenient and fast. At the same time, the oil circuit of the relevant mechanical equipment can be maintained without disassembly. High-voltage electrostatic cleaning device and method

Embodiment 1

[0019] The invention relates to a disassembly-free high-voltage electrostatic cleaning device for the oil circuit of mechanical equipment, including a pressure sensor, a stop valve, a pollution degree detector, a control system, a high-voltage electrostatic generator, a coarse filter tank, a balanced electronic filter tank, a pump, a high-voltage The nozzle and the filter device are composed of a coarse filter tank and a balanced electronic filter tank. A pressure sensor is respectively installed on the upper part of the coarse filter tank and the balanced electronic filter tank. The signal line A is connected to the input signal line of the control system, and the output signal line of the control system is connected to the high-voltage electrostatic generator. The signal input terminal of the high-voltage electrostatic generator is connected to the signal input terminal of the balanced charge reverberation device. The inlet of the coarse filter tank is connected to the outlet ...

Embodiment 2

[0026] Shanghai Tunnel Company’s Jinmen shield machine needed oil change during the construction of the Nanjing River Crossing Tunnel in July 2013. After discarding the old oil, the device of the present invention was used to clean the oil circuit. After cleaning, new oil was added. The added oil was tested The pollution level of the new oil is NAS7. After one hour of operation, it is still NAS7. After one month of use, it is still NAS7. After five months of use, it is NAS8, which is still within the normal range. Others have not been oiled. After adding new oil to the cleaned equipment, it will be NAS8 after one hour of operation. After one month of use, it will be detected as NAS9. After three months of use, it will be detected as NAS10 or above. The oil needs to be changed again. Substantial improvement, maintenance rate is greatly reduced.

Abstract

The invention relates to the technical field of mechanical equipment maintenance, in particular to a mechanical-equipment high-voltage static disassembling-free oil way cleaning device and method. The device comprises pressure sensors, a stop valve, a pollution degree detection meter, a control system, a high-voltage static generator, a rough filtering tank, a balance electronic filtering tank, a pump and a high-pressure spraying nozzle and is characterized in that a filtering device is composed of the rough filtering tank and the balance electronic filtering tank, the pressure sensors are arranged on the rough filtering tank and the balance electronic filtering tank respectively and are connected with an input signal line of the control system through a signal line A, and an output signal line of the control system is connected with a signal input end of the high-voltage static generator. Compared with the prior art, the mechanical-equipment high-voltage static disassembling-free oil way cleaning device has the advantages that cleaning can be carried out without disassembling an oil way, the phenomenon that disassembling is needed to achieve cleaning of an oil way is avoided, and the device is portable and easy to operate, saves cost and improves production efficiency; due to the adoption of the electrostatic adsorption technology, the problem that secondary pollution is generated by oil products is thoroughly solved.

Description

[technical field] [0001] The invention relates to the technical field of mechanical equipment maintenance, in particular to a high-voltage electrostatic cleaning method for oil circuits of mechanical equipment without disassembly. [Background technique] [0002] Mechanical equipment can be seen everywhere in life, such as automobiles, ships, trains, machine tools, plastic machinery, engineering machinery, petrochemical machinery, generators, etc. Most of the existing mechanical equipment will use lubricating oil and hydraulic oil during use , these oils need to be replaced after being used for a certain period of time due to contamination or aging deterioration. When replacing, the old oil must be released through the oil outlet and then injected with new oil. Because there is still a certain amount of old oil and oil in the oil circuit when the old oil is released. If the pollutants are not cleaned up thoroughly, it will cause secondary pollution to the injected new oil, ac...
