Embodiment 1

[0028] figure 2 Shown is a schematic diagram of the composition of the device for exhausting the oil inlet pipeline of a diesel engine in an embodiment of the present invention; image 3 Shown is a schematic diagram of the working process of the device for exhausting the oil inlet pipeline of a diesel engine in an embodiment of the present invention. combine figure 2 and image 3 As shown, in the embodiment of the present invention, the device for exhausting the oil inlet pipeline of a diesel engine includes an air passage 1, and one end of the air passage 1 is connected with an air source (not shown in the figure), and a pressure port 2 is arranged at the other end. . Among them, the gas path 1 can use the gas line on the automobile manufacturing production line, and the cost is low. Through the pressure port 2, the air circuit 1 is sealed and connected to the oil inlet end of the diesel engine oil inlet pipeline 20, and the diesel engine oil inlet pipeline 20 on the oi...

Embodiment 2

[0039] This embodiment provides a method for exhausting the oil inlet pipeline of a diesel engine by using the exhaust device in the first embodiment, which specifically includes the following steps:

[0040] Step S1, disconnecting the sealing connection between the oil outlet end of the diesel engine oil inlet pipeline and the oil inlet of the high pressure oil pump;

[0041] Generally, it is to directly pull out the diesel engine oil inlet pipeline on the oil inlet of the high pressure oil pump.

[0042] Step S2, sealingly connecting the gas path with the oil inlet end of the diesel engine oil inlet pipeline through the pressurizing port, wherein the gas pressure value on the gas path is a set value;

[0043]In order to facilitate the sealing connection between the pressure port and the oil inlet end of the diesel engine oil inlet pipeline, before this step, the air path between the pressure port and the oil inlet end of the diesel engine oil inlet pipeline can be cut off. ...

Abstract

The invention relates to the fuel oil supply system of a diesel engine and discloses a device and a method for exhausting the oil inlet pipeline of the diesel engine. A gas circuit is designed, one end of the gas circuit is connected with a gas source, and the other end of the gas circuit is provided with a pressurizing opening. The gas circuit is communicated with the oil inlet end of the oil inlet pipeline of the diesel engine in a sealed manner through the pressurizing opening, the oil inlet pipeline on a high-pressure oil pump oil inlet is pulled out, a manual oil pump is pressed to pump oil, the oil inlet pipeline of the diesel engine can be filled with diesel oil fast under the pressure of the gas in the gas circuit, the gas in the oil inlet pipeline of the diesel engine can be exhausted by 3-5 times of pressing generally, labor intensity is lowered greatly, and exhausting efficiency is increased. In addition, the device is simple in structure, low in production cost, convenient in exhausting operation, free of power consumption and energy saving.

Description

technical field [0001] The invention relates to a fuel oil supply system of a diesel engine, in particular to a device and method for exhausting an oil inlet pipeline of a diesel engine. Background technique [0002] combine figure 1 As shown, the fuel supply system of the diesel engine includes a fuel tank 10, a fuel tank switch (not shown in the figure), an fuel inlet pipeline 20, a hand oil pump 30 and a filter 60 arranged on the fuel inlet pipeline 20, and the fuel tank switch is sealedly installed in the On the fuel tank 10, the fuel tank 10 also has a filling port 40 for filling diesel oil. The oil inlet end of the oil inlet pipeline 20 is connected with the oil outlet of the oil tank switch through bolts, and the oil outlet end is connected with the oil inlet 70 of the high pressure oil pump 50 through bolts. When there is diesel fuel in the fuel tank 10, as long as the fuel tank switch is turned on, the diesel fuel in the fuel tank 10 will continuously flow into th...
