Description

급유장치Lubrication device

본 발명은 복수의 저유탱크내의 기름을 균등하게 사용할 수 있도록 한 급유장치로서, 특히 각 저유탱크에 마련한 수중펌프(Submersible pump)를 공통의 급유관을 통해서 복수대의 계량기에 접속한 급유장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lubrication device for equally using oil in a plurality of oil storage tanks, and more particularly, to an oil supply device in which a submersible pump provided in each oil storage tank is connected to a plurality of meters through a common oil supply pipe. .

급유소의 각 저유탱크의 기름을 균등하게 사용할 수 있도록 한 것은 일본 특개 소64-23998호로서 알려져 있다. 이것은 각 저유탱크를 싸이폰관으로 접속하여 액면위치의 차가 생기지 않도록 하고 있어서, 각 저유탱크의 기름을 균등하게 사용하는 점에서는 유효하지만 별개로 싸이폰관을 마련할 필요가 있어 비용이 커지는 불합리함이 있다. 또 저유탱크로 기름을 보급할 때에는 싸이폰 작용을 정지시키고 보급이 끝난 후에 재차 싸이폰작용을 작동시키는 까닭에 복잡한 구조로 되어 있다.It is known as Japanese Patent Application Laid-Open No. 64-23998 that allows the oil in each oil storage tank of the gas station to be used evenly. This is effective in connecting oil storage tanks to each other by the use of cyphon pipes to prevent the difference in liquid level, and it is effective in equally using oil in each oil storage tank, but it is necessary to provide a separate cyphon pipe, which makes the cost unreasonable. . In addition, when oil is supplied to the oil storage tank, the siphon operation is stopped, and after the supply is completed, the siphon operation is operated again.

이러한 불합리함을 해소하기 위하여 본 출원인은 일본 특원 평8-67313호에서 각 저유탱크에 마련된 액면계의 액위(液位)신호로부터 액량을 구하여, 액량이 많은 저유탱크의 수중펌프를 우선적으로 구동하도록 한 급유장치를 제안하고 있다. 이것은 각 저유탱크의 유량이 같아질때까지 절대 용량이 많은 저유탱크의 수중펌프가 우선적으로 구동되어지게 되므로써 기름이 균등하게 사용되지 않는 불합리함이 있다.In order to solve such unreasonableness, the present applicant obtains the liquid amount from the liquid level signal of the liquid level gauge provided in each oil storage tank in Japanese Patent Application No. Hei 8-67313, and preferentially drives the submersible pump of the oil storage tank having a large amount of liquid. Oiling device is proposed. This is unreasonable in that oil is not used evenly because the submersible pump of a large capacity oil storage tank is operated preferentially until the flow rate of each oil storage tank is the same.

여기서 본 발명이 목적으로 하는 바는 저유탱크의 용량이 다른 경우에도 각 저유탱크의 기름을 균등하게 사용될 수 있는 급유장치를 제공하는 것이다.It is an object of the present invention to provide a lubrication device that can be used evenly in each oil storage tank even if the capacity of the oil storage tank is different.

상기 목적을 달성하기 위하여 본 발명은 복수의 저유탱크와, 각 저유탱크에 마련된 액면계 및 수중펌프와, 각 수중펌프의 토출관에 접속된 공통의 급유관을 통해서 접속된 복수대의 계량기와, 각 액면계로부터의 신호에 의거하여 각 저유탱크의 잔량비율을 연산하며, 계량기로부터의 급유요구신호를 받았을 때에 잔량 비율이 높은 저유탱크의 수중펌프에 구동신호를 출력하는 제어장치로서 구성되어 있다.In order to achieve the above object, the present invention provides a plurality of oil storage tanks, a liquid level meter and a water pump provided in each oil storage tank, a plurality of meters connected through a common oil supply pipe connected to the discharge pipe of each submersible pump, and each liquid level meter. It is configured as a control device that calculates the residual ratio of each oil storage tank based on a signal from the oil storage tank, and outputs a drive signal to the submersible pump of the oil storage tank having a high residual ratio when receiving a fuel supply request signal from the meter.

그리고 상기 제어장치는 각 저유탱크의 액량을 계산하는 데이터를 기억한 계산데이터기억수단과, 그 계산데이터기억수단에 기억되어 있는 계산데이터와 액면계의 액위신호로부터 액량을 연산하는 액량수단과, 각 저유탱크의 용량을 기억한 탱크용량기억수단과, 그 탱크용량기억수단에 기억되어져 있는 용량과 상기 액량연산수단에서 구하여진 액량과에 의해 잔량비율을 연산하는 비율연산수단과, 그 비율연산수단에서 연산된 각 저유탱크의 잔량비율의 높고 낮음을 비교하는 비교수단과, 계량기로부터 급유요구신호를 받았을 때에 잔량비율이 높은 저유탱크의 수중펌프에 구동신호를 출력하는 펌프구동수단과를 구비하고 있으므로서 용량이 다르다고해도 각 저유탱크의 기름을 균등하게 사용할 수 있도록 수중펌프를 가장 적당하게 제어할 수가 있다.The control apparatus includes calculation data storage means for storing data for calculating the liquid level of each oil storage tank, liquid level means for calculating the liquid amount from the calculation data stored in the calculation data storage means and the liquid level signal of the liquid level gauge, and each oil storage.
