Description
Technical Field
The invention relates to the technical field of on-line monitoring, signal imaging and signal transmission, in particular to a method and a device for monitoring a floating oil outlet device of an oil tank.
Background
According to the requirement of the international civil aviation organization on airplane refueling, a floating oil outlet device is required to be installed on an airport oil storage tank. Because the liquid subsides, moisture and impurity in the oil sink at the tank bottoms, and the oil outlet of floating device can change the oil tank oil outlet from the bottom to the position about 1 meter below the liquid level layer, can send out the clean fuel in liquid level layer all the time to the cleanliness factor of safer assurance aircraft oil.
When the oil tank floating oil outlet device is used, the oil tank can not be used for oil, and oil supply of an airport is interrupted due to the fact that the head of the oil tank is warped and the oil outlet floats out of the liquid level due to the fact that air is stored in the oil tank and the rotary joint is clamped and stuck. Therefore, a great deal of research is carried out on the monitoring of the running state of the oil tank floating oil outlet device at home and abroad, and a plurality of monitoring methods are put forward in combination with practical use. The domestic research of monitoring the operating condition of the floating oil production device begins in the ninth decade of the last century and is mainly detected by visual inspection, rope inspection and a floating pipe indicator:
(1) visual inspection: the state of the floating oil outlet device is visually observed through the lighting hole. When the floating oil outlet device stops oil sending operation, a worker opens a blind plate of a lighting hole at the top of the tank, and the approximate position of a floater of the floating oil outlet device is visually observed through the lighting hole to judge whether the working state of the floating oil outlet device is normal. The visual inspection method is only suitable for a vertical oil tank or a horizontal oil tank without an internal floating plate, has great limitation, cannot judge the impact force generated by air storage or air intake in a floating pipe and the real-time early warning of possible equipment damage, and is far from being suitable for the requirements of information and intelligent management of an oil depot.
(2) Inspecting the inspection rope: some airport oil depot oil tanks have installed the safety inspection rope on tank deck portion daylighting hole blind plate, and the artifical manual safety inspection rope of pulling of accessible judges that the oily device of floating appears the jamming phenomenon. This method requires careful design and installation to prevent the inspection line from tangling and interfering with the branch pipes and other equipment inside the tank.
(3) A floating pipe indicator: the floating pipe indicator is only suitable for a single-arm oil tank floating oil outlet device and is not suitable for a double-arm or multi-arm floating oil outlet device. The working height of the floating pipe is indicated according to the angle change of the rotary joint so as to display whether the floating pipe works normally or not and to display whether the floating pipe is lifted or lowered. The float tube indicator is a mechanical indicator. The floating pipe indicator is arranged on the pipe wall or the tank top and is connected with a rotary joint in the tank through a steel wire rope, and the floating pipe indicator can only display the approximate position of the working height of the floating pipe and judge whether the floating pipe is in a working state or not. The device can not monitor the dynamic influence of oil density, floating pipe air intake and the like on the stress of the top end of the floating pipe, has the functions of fault early warning judgment and the like, and does not have the foundation of signal imaging, data remote transmission and linkage control of valve opening and closing and pump starting and stopping.
In summary, the three monitoring methods have high labor intensity and cannot monitor and record the running state in real time, and once an accident occurs, scientific basis is lacked for analyzing the fault reason, making targeted countermeasure measures and the like.
