Abstract
The embodiment of the invention discloses a brushless fuel pump. A control circuit of the fuel pump is isolated from an oil path by a plastic sealing device. In the embodiment of the invention, the control line of the circuit and a motor oil pumping path are completely isolated by plastic sealing, and a current circuit is completely converted in a sealed space, so that the contact and corrosion of a circuit part in methyl alcohol gasoline can be completely avoided, sparks caused by water can also be completely avoided, and motor running is not interfered. M85 methyl alcohol gasoline is burnt more thoroughly than gasoline so that emission of M85 automobile tail gas is obviously reduced, and therefore, the brushless fuel pump has an environmental-protection value.
Description
Technical field
The present invention relates to brushless click technical field, more particularly, relate to a kind of brushless fuel pump.
Background technique
The fuel that present China automobile now uses is 90#, 93#, 97# gasoline, and these fuel all are non-renewable.Domestic Shanxi, Henan, the several domestic city in Jiangxi and external South America Brazil, Argentinian country etc. have brought into use the M85 methanol gasoline to substitute existing 90#, 93# gasoline.85% methyl alcohol+15% gasoline+additive during the Main Ingredients and Appearance of M85 methanol gasoline, wherein methyl alcohol is that generative fuel can extract from our wheat, Chinese sorghum, corn, water hyacinth, coal, wheat, Chinese sorghum, corn, water hyacinth all are aftergrowths, and growth is fast, and cost is low.The M85 methanol gasoline can substitute 90#, 93# fuel oil fully.Use methanol gasoline can reduce the pollution of automobile, can save the use of parent fuel, reduce the fuel oil consumption of autoist environment.China is also at standard and the experimental city of September 1 day having put into effect M85 methanol vehicle of this project in 09 year, mainly is to concentrate on Shanxi, Shaanxi, Henan to carry out local popularization and use, thereby promote to the whole nation.And concentrate on fuel pump core in the oil supply system at the subject matter of methanol vehicle in China's automobile fitting industry now.
The fuel pump core of automobile all is the brush direct current motor that adopts now, and brush direct current motor all can normally use in 90#, 93# gasoline, but can not use in the M85 methanol gasoline.Because methanol concentration is too high in the M85 methanol gasoline, component are all had the corrosion of height, and commutator is easy to sulfuration, the aging distortion of the component that circuit transmits, thus cause automobile ignition difficulties in use, difficult in acceleration, situation such as the life-span is low.It is that oil circuit and circuit are not isolated that the existing structure of brush fuel oil motor is arranged, and thereby complex structure, instability, life-span are low causes above problem, also do not have aly have brush fuel oil motor can satisfy use fully according to market survey now, and common brushless electric machine can not be accomplished the sealing fully of oil circuit and circuit, and a lot of component are not corrosion-resistant, cause electrode normally not use.
Summary of the invention
