DETAILED DESCRIPTION

[0024] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0025] like Figure 1-Figure 2 As shown, a mobile lubricating oil filling machine includes a mobile chassis, an oil extraction pipe 13, a moisture sensor 12, an oil pump 11, a Y-type filter 8 and a refueling gun 7;

[0026] The outlet end of the oil extraction pipe 13 is connected to the oil inlet of the oil pump 11 through a pipeline, and the oil outlet of the oil pump 11 is connected to the refueling gun 7 through a pipeline;

[0027] A moisture sensor 12 is installed in the pipeline between the oil extraction pipe 13 and the oil pump 11, and a Y-type filter 8 is installed in the pipeline between the oil pump 11 and the refueling gun 7;

[0028] The oil extraction pipe 13 is a hard pipe. The outer wall of the oil extraction pipe 13 is provided with a sealing threaded sleeve. The inner ring of the sealing threaded sleeve is a sealing ring structure. The sealing ring slides and seals with the outer wall of the oil extraction pipe 13. The outer ring of the sealing threaded sleeve is a thread 15.

[0029] When in use, the inner ring of the sealing threaded sleeve 15 of the device is slidably and sealedly assembled with the outer wall of the oil extraction pipe 12. The outer ring of the sealing threaded sleeve 15 is assembled with the inner thread of the oil barrel mouth through a thread, so that the oil extraction pipe and the oil barrel are sealed and there is no gap. This will not cause pollution to the inside of the lubricating oil barrel. The entire oil circulation process from the oil extraction end to the oil filling end is sealed. In addition, if the refueling port of the industrial equipment has been modified with a quick interface, the oil outlet of the filling machine can be directly connected to the equipment tank filling port through a quick connector to achieve closed filling. In addition, the device has a moisture sensor installed on the upstream part of the oil pump to collect the moisture data of the lubricating oil. This can prevent the addition of lubricating oil with excessive moisture into the equipment and cause equipment failure. The mobile chassis of the device is used to place the lubricating oil barrel, so that the oil barrel can move with the filling machine, which is convenient to move when changing position. The Y-type filter 8 serves as a three-stage filtration device.

[0030] The oil inlet end of the oil extraction pipe 13 is provided with a one-way valve 14 , and the inlet end of the one-way valve 14 is provided with a filter.

[0031] A check valve 14 is installed at the oil inlet end of the pumping pipe 13 to prevent the pumped oil from flowing back into the oil drum. If the oil level inside the pumping pipe drops, and the oil drum level is too low, air may be mixed with the oil during initial refueling, causing a false refueling amount and misjudging the personnel. The filter acts as a primary filter, preventing large particles from entering the pipeline. The installation of the check valve 14 ensures that the pumping pipe 13 is always filled with oil, preventing the presence of air in the pipe during secondary extraction, which would cause air and oil to be extracted together.

[0032] The system further includes a lubricating oil filter 9 , which is installed in the pipeline between the Y-type filter 8 and the oil pump 11 .

[0033] The lubricating oil filter 9, located downstream of the oil pump, also serves as the secondary filtration system. From the moment the oil enters the system, it undergoes three stages of filtration: a screen, lubricating oil filter 9, and a Y-type filter 8. This three-stage filtration ensures the lubricating oil can flow out of the fueling nozzle 7. The two ends of the lubricating oil filter 9 are threaded together, connecting to the oil pipeline. The integrated filter design facilitates routine replacement and maintenance. A Y-type filter 8, threadedly installed at the front of the fueling nozzle (including the flowmeter) 7 and the oil outlet pipe, provides the third stage of filtration.

[0034] The oil pressure stabilizing cup 10 is also included, and the oil pressure stabilizing cup 10 is installed in the pipeline between the lubricating oil filter 9 and the oil pump 11.

[0035] In addition, the mobile chassis includes a tray portion 3, an equipment box 1 and an armrest 2;

[0036] The tray portion 3 is in the shape of a flatbed truck, the two support columns of the handrail 2 are respectively and vertically fixedly installed on both sides of the rear portion of the tray portion 3 , and the equipment box 1 is fixedly installed in the middle of the rear portion of the tray portion 3 .

[0037] In addition, a pipe hanging rack is provided on the outside of the equipment box 1;

[0038] The lubricating oil filter 9, the oil pressure stabilizing cup 10 and the oil pump 11 are fixedly installed inside the equipment box.

[0039] In addition, the handrail 2 is equipped with a fixing buckle 6 for the oil extraction pipe 13.

[0040] In addition, a load-bearing wheel 5 is installed at the front end of the tray portion, and a plurality of universal wheels 4 are installed at the rear end of the tray portion.

[0041] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
