Embodiment 1

[0038] As the most basic embodiment of the present invention, such as figure 1 As shown, a purifying device for the full oil volume of a refueling device includes a main oil tank 1 and an auxiliary oil tank 6 for containing oil, and the bottoms of the main oil tank 1 and the auxiliary oil tank 6 are provided with oil outlets, connected with The pipeline connects the oil outlet of the main oil tank 1, the control valve 9, the one-way valve, the filter 5 and the outlet of the auxiliary oil tank 6. Preferably, the control valve 9 adopts a three-position four-way reversing valve and a two-position two-way valve, and the three-position four-way reversing valve is respectively connected with the oil in the main oil tank 1 and the auxiliary oil tank 6 The outlet is connected, and the two-position two-way valve is connected in series with the filter 5 on the same pipeline.

[0039] The purification device uses an oil pump 3 as a power mechanism to drive the oil to move between the ma...

Embodiment 2

[0053] As a preferred embodiment of the present invention, such as figure 2 As shown, the oil outlets of the main oil tank 1 and the auxiliary oil tank 6 are provided at the bottom, and the oil outlet of the main oil tank 1, the control valve 9, the filter 5 and the oil outlet of the auxiliary oil tank 6 are connected by connecting pipelines. A liquid level switch 2 is arranged at the bottom of the main oil tank 1 and the auxiliary oil tank 6, and a liquid level gauge 10 is arranged in the main oil tank 1. The controller 7 collects signals such as the liquid level gauge 10 and the liquid level switch 2. The main oil tank 1 and the auxiliary oil tank 6 are charged / released from the outside through the inflation / deflation nozzle 8, and the inflation / deflation nozzle 8 and the control valve 9 are all controlled by the controller 7.

[0054] In this embodiment, the capacity of the main fuel tank 1 / auxiliary fuel tank 6 is designed according to the requirement of refueling quanti...

Abstract

The invention discloses a purification method and device for full-oil-quantity oil of a refueling device and belongs to the technical field of oil product filtering in the field of hydraulic pressureand lubrication. The purification device comprises a main oil tank and an auxiliary oil tank which are communicated with each other through a connection pipeline, and electric elements including a control valve, a filter, a check valve group and an oil pump which are arranged on the connection pipeline. Under the action of a controller, oil in the main oil tank is pumped out through the oil pump and passes through the control valve and the filter; when a liquid level meter monitors that all the oil flows into the auxiliary oil tank, first-time filtering is finished; then the controller is started and the oil pump is used for pumping out the oil from the auxiliary oil tank; the oil flows through the control valve and the filter and then flows back into the main oil tank to finish second-time filtering. According to the purification method and device, disclosed by the invention, the problems of dilution, sedimentation and the like in a circulating process of a traditional method are avoided; the problems that the purification efficiency of the traditional method is not high, a system is complicated and the like are effectively solved; the time of preparing a refueling task can be extremely shortened.

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 a method and device for purifying the full oil volume of a refueling device. Background technique [0002] The working performance of the construction machinery hydraulic system directly affects the reliability of the construction machinery, and the hydraulic oil, as the medium of energy transmission, also has the functions of cooling, lubrication and rust prevention, which plays a decisive role in the normal operation of the hydraulic system . The oil purification method of the traditional refueling device or equipment is as follows: the oil is pumped out from the oil tank through the pump, filtered by the filter and then returned to the oil tank to form a cycle. Through long-term circulation, dilution and filtration, the effect of oil purification is achieved, but this There are many problems and deficiencies in this me...
