Online pump bracket of fuel system

燃油系统的在线泵支架

Abstract

本发明公开了一种燃油系统的在线泵支架,包括储油桶、法兰,储油桶内设置电动燃油泵、初滤器、调压阀、喷射泵;电动燃油泵的底部连接初滤器;储油桶顶部设置法兰,法兰设置进油管、通气管、出油管;进油管的一端连接油箱,另一端通过输油管连接喷射泵;通气管的一端连接油箱,另一端通入储油桶;出油管的一端连接发动机,另一端通过多通管接头同时与电动燃油泵出油口和调压阀连接。本发明通过喷射泵将油箱内的油带到储油桶中,使油箱内的油快速进入供油系统,能够克服现有的在线泵产品仅依靠燃料油自重进入供油系统的不足,避免在启动和加速的情况下出现供油不足的情况。
The invention discloses an online pump bracket of a fuel system, which comprises an oil storage drum and a flange, wherein an electric fuel pump, a primary filter, a pressure regulating valve and an injection pump are arranged in the oil storage drum; the bottom part of the electric fuel pump is connected with the primary filter; the flange is arranged at the top part of the oil storage drum, and the flange is provided with an oil inlet pipe, a vent pipe and an oil outlet pipe; one end of the oil inlet pipe is connected with an oil tank, and the other end is connected with the injection pump through an oil conveying pipe; one end of the vent pipe is connected with the oil tank, and the other end is introduced into the oil storage drum; and one end of the oil outlet pipe is connected with an engine, and the other end is simultaneously connected with an oil outlet of the electric fuel pump and the pressure regulating valve through a multi-way pipe joint. The online pump bracket of the fuel system can lead oil in the oil tank to quickly enter into an oil supply system by using the injection pump to bring the oil in the oil tank into the oil storage drum, thereby overcoming the shortcomings of an existing online pump product which leads the fuel oil to enter into the oil supply system by only relying on self-gravity of the fuel oil, and avoiding the situation of insufficient oil supply during startup and acceleration.
