Embodiment Construction

[0024] The present invention will be further described below in conjunction with examples, but the present invention is not limited to these examples.

[0025] In the fuel system, the alcohol-based fuel is delivered to the alcohol-based fuel oil pump 2 through the oil delivery pipe 1 for pressurization, and then injected. The above-mentioned oil pipeline 1 mainly includes an oil pipeline 1-1, a tee 1-2, an inlet oil pipeline 1-3 and an outlet oil pipeline 1-4. The oil pipeline 1-1 is provided with a tee 1-2, and the alcohol-based fuel flows through After the tee 1-2, it enters the alcohol-based fuel oil pump 2 through the inlet oil passage 1-3, and after being pressurized, it is sprayed out from the outlet oil passage 1-4. The alcohol-based fuel oil pump 2 mainly includes an aluminum alloy base 2-1, an exhaust valve 2-2, an aluminum alloy pipeline 2-3, a pair of fixing screws 2-4, a piston 2-5, a stainless steel casing 2-6, A pair of electromagnets 2-7 and the inner oil circu...

Abstract

The invention provides a corrosion-resistant alcohol-based fuel oil pump and a corrosion protection method. An additional power source (6) and a carbon rod (7) are connected between the alcohol-based fuel oil pump (2) and an oil conveying pipe (1) in an existing fuel system. The alcohol-based fuel oil pump (2), the additional power source (6), the carbon rod (7) and alcohol-based fuel in the oil conveying pipe (1) form a loop. By adjusting the magnitude of the voltage of the additional power source (6), the alcohol-based fuel oil pump (2) can be prevented from corrosion; and the situations that performance of the alcohol-based fuel oil pump (2) is deteriorated, the service life of the alcohol-based fuel oil pump (2) is shortened, and quality of the alcohol-based fuel is degraded are avoided. On the basis of the corrosion-resistant alcohol-based fuel oil pump (2), the resistance value of the loop formed by the alcohol-based fuel, the alcohol-based fuel oil pump (2), the additional power source (6) and the carbon rod (7) and the primary battery voltage serve as the data basis; the magnitude of the additional voltage is adjusted; and the purpose that the alcohol-based fuel oil pump (2) is resistant to corrosion is achieved.

Description

technical field [0001] The invention relates to an anticorrosion improvement and an anticorrosion method of an oil pump, in particular to a corrosion-resistant alcohol-based fuel oil pump and an anticorrosion method in a fuel system. Background technique [0002] Alcohol-based fuel is a fuel mainly composed of alcohols such as methanol and ethanol. It burns thoroughly and has high thermal efficiency. It is an environmentally friendly and energy-saving energy source that can be used in catering or industrial boilers. [0003] Alcohol-based fuel oil pumps are used in the fuel system to transport, pressurize, and inject alcohol-based fuels. However, the existing alcohol-based fuel oil pumps are all made of aluminum alloys, which have poor tolerance to the corrosion of alcohol-based fuels. During the use of the oil pump, the oil circuit in the alcohol-based fuel oil pump and the aluminum alloy pipeline will be corroded. Clearance affects the accuracy of alcohol-based fuel oil p...
