When the equipment is running, the lubricating oil circulates and lubricates the parts in the mechanical equipment, thereby improving the stability of the mechanical equipment and extending its service life.

[0003] However, during the long-term circulation and lubrication process, lubricating oil will contain impurities such as iron filings and dust. If too many impurities are present, they will cause wear and tear on the internal parts of the equipment during the circulation of the lubricating oil, reducing the service life of the equipment. Therefore, it is necessary to replace the lubricating oil in the oil tank regularly.

[0023] The beneficial effects of this utility model are:

[0024] 1. An oil pump is installed on the oil tank. Two three-way valves, one for the inlet and one for the outlet, are installed on either side of the pump. One end of each valve is fixedly connected to the pump's inlet and outlet ports, respectively. Oil pipes are fixedly installed on the other ends of both valves, with the other ends connected to the inside of the oil tank. This mobile refueling device can be used as a fixed pump station, a mobile pump station, a mobile refueling station, or a mobile oil pump. When used as a fixed pump station, an oil source is connected to the inlet of the three-way valve, and a metering nozzle is connected to the outlet of the three-way valve. Operating the inlet valve closes its connection to the inside of the oil tank while simultaneously connecting the oil source to the inlet. Then, operating the outlet valve closes its connection to the inside of the oil tank, achieving a direct connection between the oil source and the metering nozzle. This device is used for metering refueling at a fixed pump station, saving time and effort and increasing operational efficiency.

[0025] When used as a mobile pump station, one operating method is to connect an oil source to the oil inlet of the three-way valve at the oil inlet end, operate the three-way valve at the oil inlet end to connect the three-way valve at the oil inlet end to the inside of the oil tank, and realize non-powered refueling by relying on the liquid level difference.

[0026] Another operating method is to operate the three-way valve at the oil inlet end to close its interface to the oil tank, and at the same time connect the oil inlet to the oil pump inlet. Operate the three-way valve at the oil outlet end to close the oil outlet, and at the same time connect the oil pump outlet to the oil tank. Turn on the oil pump motor switch to realize electric oil pumping to add oil to the oil tank. During the oil filling process, observe the liquid level thermometer and control the amount of oil added.

[0027] When used for mobile refueling, operate the three-way valve at the oil inlet end to close its oil inlet, and at the same time connect the oil tank and the oil pump's oil inlet. Operate the three-way valve at the oil outlet end to close its interface to the oil tank, and at the same time connect the oil pump's oil outlet and the oil outlet. Connect the oil outlet to the refueling nozzle, and move the device next to the equipment to achieve mobile refueling.

[0028] When used for mobile oil pumping, first, empty the oil tank through the drain valve, move the device next to the pumping equipment, operate the three-way valve at the inlet end to close its interface to the oil tank, and at the same time, connect the inlet to the inlet of the oil pump. Operate the three-way valve at the outlet end to close the outlet, and at the same time, connect the outlet of the oil tank to the outlet of the oil pump, and connect the inlet to the outlet of the tank to be drained to realize the oil pumping operation. It can be seen that the device can be used as a fixed pumping station, a mobile pumping station, a mobile refueling station, and a mobile oil pumping station, with a wide range of applications and few limitations.

[0029] 2. The fuel tank is also equipped with a battery pack, which is electrically connected to the fuel pump to supply power to the fuel pump, thereby enabling wireless power supply for the refueling device and eliminating the limitation of wired power supply.

[0030] 3. The mobile refueling device is equipped with a metering refueling nozzle, which has a quantitative system that can set the required amount of refueling. When quantitative refueling is required, the metering refueling nozzle can be connected to the oil outlet of the three-way valve at the oil outlet end to achieve quantitative refueling.
