Liquid level display and automatic oil supply device for elevated oil tank

Abstract

The invention discloses a liquid level display and automatic oil supply device for an elevated oil tank. The liquid level display and automatic oil supply device comprises a floor oil tank and the elevated oil tank. Both the floor oil tank and the elevated oil tank are electrically connected with a control system used for controlling the floor oil tank to inject oil into the elevated oil tank at the same time. The control system comprises a manual operation part and an automatic operation part, and the two parts can work simultaneously. When alarm failures happen to the automatic operation part and repair cannot be realized, the manual operation part can be used for control. According to the liquid level display and automatic oil supply device, automatic oil supply can be achieved through the automatic operation part of the control system. By means of the device, the labor intensity of workers in a machine room is relieved, hidden dangers caused by an upper elevated tank and a lower elevated tank are eliminated, reliability and stability of oil supply are improved, and normal operation of a diesel engine and normal production are guaranteed.

Description

technical field [0001] The invention relates to an automatic oil supply device, in particular to an elevated tank liquid level display and automatic oil supply device, which belongs to the technical field of petroleum machinery. Background technique [0002] In the drilling team, the elevated oil tank is an important part of the drilling power diesel engine oil supply system, and the fuel required by the diesel engine is delivered to the engine room or power generation room through the pressure difference generated by the elevated oil tank. In the past, the oil replenishment of the elevated oil tank was always started manually by the personnel in the machine room, and then visually observed the liquid level of the elevated oil tank to decide when to stop the oil supply motor. To complete the judgment of the oil quantity, it is necessary to climb up and down, and the risk factor is very high; especially in the season of bad weather such as rain and snow, it is more dangerous ...

AI Technical Summary

Problems solved by technology

To complete the judgment of oil quantity, it is necessary to climb up and down, and the risk factor is very high; especially in the season of bad weather such as rain and snow, it is more dangerous to climb up and down the elevated oil tank. At the same time, due to the increased labor intensity of drilling workers , During special construction operations, due to the negligence of the operators in the drilling rig room, the following casings may forget to replenish fuel oil to the elevated fuel tank in time, and the diesel engine will stop due to the low oil tank, which will lead to hidden dangers of production and downhole accidents
