Problems solved by technology
In addition to the cutting function, all other actions of the roadheader rely on the hydraulic system to provide power. Most of the failures of the hydraulic system are caused by hydraulic oil pollution, which leads to shutdown and production, which affects work efficiency.
At present, in the hydraulic system of the roadheader, in order to ensure the normal operation of the system, low-precision filters are generally arranged. The equipment works under harsh conditions for a long time, which can easily lead to oil pollution and damage hydraulic components.
In the existing technology, oil is taken from the main oil pump, which will inevitably affect the flow rate of the hydraulic system. When the system is working at high pressure, the high-pressure oil in the oil return part enters the filter, which increases the pressure resistance requirement of the filter.
At the same time, high-pressure oil directly enters the oil tank, which affects the safety of the hydraulic system

The invention provides an on-line oil purification system of a heading machine and the heading machine, and belongs to the technical field of engineering machine.The on-line oil purification system of the heading machine comprises a hydraulic oil tank; the heading machine hydraulic system is connected with the hydraulic oil tank and used for driving the heading machine to work, and the heading machine hydraulic system comprises a main oil pump set; the series pump is in through shaft connection with the main oil pump set, and an oil inlet of the series pump is connected with the hydraulic oil tank; an oil inlet of the fine filtering system is connected with an oil outlet of the series pump, and an oil outlet of the fine filtering system is connected with the hydraulic oil tank. By means of the technical scheme, online oil forced filtering can be conducted while the heading machine works, the oil cleanliness is guaranteed, no extra power source needs to be added, the fault rate of a hydraulic system is reduced, and the service life of equipment is prolonged.
Description
technical field [0001] The application belongs to the technical field of construction machinery, and in particular relates to an on-line purification system for roadheader oil and a roadheader. Background technique [0002] Due to the particularity of the mining environment, the excavation surface is full of pollutants such as particles, dust, mud, etc., which seriously threaten the operation safety of the hydraulic system. Except for the cutting function, the other actions of the roadheader all rely on the hydraulic system to provide power. Most of the hydraulic system failures are caused by the contamination of the hydraulic oil, resulting in shutdown and production shutdown, affecting work efficiency. At present, in the hydraulic system of the roadheader, in order to ensure the normal operation of the system, low-precision filters are generally arranged, and the equipment works under harsh working conditions for a long time, which can easily lead to oil pollution and dama...
