Abstract

The invention discloses an oiling method and device, and belongs to the technical field of liquid fuel conveying. The invention solves the problem that the long-term non-running oil supply system cannot be put into use in time when meeting emergency use conditions because the connecting pipeline between the oil suction pump and the oil reservoir is not full of fuel oil. The oiling method comprises the steps of judging whether an oil suction pump is started, stopping automatically oiling the first oil supply pipeline if the oil suction pump is started, enabling the first oil supply pipeline to always keep an oil-filled state if the oil suction pump is started, and enabling one end of the first oil supply pipeline to be connected with the oil suction pump and the other end of the first oil supply pipeline to be arranged in an oil warehouse. According to the invention, when the oil suction pump does not work, the first oil supply pipeline is continuously filled with oil, so that the first oil supply pipeline is always in an oil filled state, and the oil suction pump is started, so that fuel oil can be immediately sucked from an oil reservoir, and the emergency situation is met.

Description

Oiling method and device Technical Field The invention relates to the technical field of liquid fuel delivery, in particular to an oiling method and device. Background The oil depot is a special device for storing oil, and comprises an underground oil depot, namely an oil depot arranged underground, such as an underground oil tank. Because the underground oil reservoir is arranged underground, the oil suction pump for sucking oil from the underground oil reservoir is arranged on the ground, and the oil suction pump can suck fuel oil from the underground oil reservoir, the oil suction pump is connected with the underground oil reservoir through a connecting pipeline, and the oil suction pump can suck fuel oil from the underground oil reservoir only after the connecting pipeline is filled with the fuel oil, so that the oil supply system can normally operate. The prior oil injection mode for the front pipeline of the oil suction pump is that the connecting pipeline is connected with a funnel, and fuel oil is injected into and filled in the connecting pipeline through the funnel in a manual mode. Under the condition that the oil supply system does not operate for a long time, the oil shortage of the connecting pipeline is large, a large amount of fuel oil needs to be carried when the oil is manually replenished, and the labor is consumed, and when the fuel oil is injected into the connecting pipeline, the time is consumed, so that the oil suction pump is started to suck the oil for a long time, and the problem that the oil supply system which does not operate for a long time cannot be put into use in time when the oil supply system encounters emergency use conditions is caused. Disclosure of Invention In view of the above analysis, the present invention aims to provide an oiling method and system, which are used for solving the problem that an oil supply system which does not operate for a long time cannot be put into use in time when encountering emergency use condition due to the fact that a connecting pipeline between an oil suction pump and an oil reservoir is not full of fuel oil.
