fuel oil transfer system

Abstract

The present invention provides a transfer system of fuel oil capable of suppressing waste when fuel oil stored in a plurality of tanks is consumed. The transfer system of fuel oil heats the fuel oil transferred from one of the plurality of fuel oil storage tanks (2A) and (2B) through the fuel oil sedimentation tank (3), and returns the heated fuel oil to the fuel oil. The fuel oil storage tank ismixed with the fuel oil in the fuel oil storage tank, whereby the temperature of the fuel oil in the fuel oil storage tank can be locally increased, which is characterized by the fuel oil introduced by the transfer pump (6) after the temperature and / or the inflow pressure is lowered or the driving power is abnormally increased and the transfer pump (6) is forcibly stopped, the system can select aprocess of heating the down pump (11) while operating. The process of the fuel oil flows to the fuel oil introduction side of the transfer pump (6): and the process of operating the down pump (11) isperformed while operating the transfer pump (6).

Description

technical field [0001] The present invention relates to a fuel oil transfer system, and more particularly, to a fuel oil transfer system for transferring fuel oil between fuel oil storage tanks. Background technique [0002] Fuel oil used in boilers such as ships and generators is stored in storage units such as tanks, and is supplied to internal combustion engines and the like for consumption. In addition to fuel oil, lubricating oil for host machines such as internal combustion engines is stored in a storage unit such as a tank similarly to fuel oil and used. [0003] There are cases where a plurality of tanks are prepared for fuel oil and lubricating oil storage units used in ships, depending on the type of properties, different storage amounts, etc. (for example, Patent Document 1). [0004] Patent Document 1 discloses a configuration in which one of a plurality of tanks storing lubricating oil having different properties is selected when replenishing lubricating oil co...

Problems solved by technology

[0007] However, the structure disclosed in Patent Document 1 is only based on the premise of selecting any one of a plurality of tanks, and does not consider the transfer of objects having the same properties such as fuel oil between tanks.

[0008] Therefore, since the small amount of fuel oil remaining in the tank is left intact without being consumed, it is not conducive to implementing energy saving that suppresses wasteful consumption of fuel.
