Flexible liquid tank control system

Abstract

The invention discloses a flexible liquid tank control system which comprises a tank body, an electric valve bank, a liquidometer, a PLC control cabinet and an upper computer, wherein the tank body comprises a plurality of tank cabins connected by bottom manifolds, and a liquid outlet pipeline and a liquid inlet pipeline are separately arranged at the head and tail of the tank body; the electric valve bank is arranged in the liquid outlet pipeline and the liquid inlet pipeline of the tank body for controlling input and discharge of an oil liquid; the liquidometer is arranged in the liquid outlet pipeline for metering the oil liquid level in the current tank body; the PLC control cabinet is mounted at the bottom of the tank body, and the PLC control cabinet is electrically connected to theelectric valve and the liquidometer; and the upper computer is connected to the PLC control cabinet and controls the electric valve according to the liquid level information to adjust the liquid levelheight in the tank body automatically. As the PLC controller is connected to the upper computer to control a valve at the liquid outlet end and a valve at the liquid inlet valve of the liquid tank inreal time, so that remote liquid supply and drainage are controlled, and the labor intensity of an operator is reduced. Meanwhile, by arranging the liquidometer, the liquid level condition in the tank can be monitored in real time, so that the liquid tank is prevented from being evacuated.

Description

technical field [0001] The invention relates to the field of oil and gas construction, in particular to a flexible liquid irrigation control system. Background technique [0002] Oil and gas extraction is the process of extracting oil and natural gas buried in underground oil layers from the ground. At the oil and gas construction site, the construction personnel will frequently manually control the liquid inlet valve and the liquid outlet valve of the liquid storage and supply tank according to the construction requirements. The existing scheme, when the liquid irrigation is used, often causes the liquid level in the tank to be incorrectly stored. If the position height is not understood, the liquid tank may overflow and evacuate due to the manual operation of the valve not in time. In order to prevent liquid tank overflow and liquid irrigation pumping out during oil and gas exploitation, a flexible liquid irrigation control system is needed. Contents of the invention ...
