Description
Technical field
The utility model relates to a kind of fuel pump, relates in particular to a kind of brushless methanol fuel pump.
Background technique
At present, the fuel pump of prior art, comprise rear end cover assembly, stator, rotor, the pump housing, pump core, pump cover and shell, rotor and pump core are in transmission connection, and the pump core is placed in the pump chamber consisted of the pump housing and pump cover, between rotor and stator, form rotor chamber, shell is fixed together rear end cover assembly, stator, the pump housing and pump cover, and pump cover is provided with filler opening, and the rear end cover assembly is provided with oil outlet, fuel oil enters from filler opening, after the rotor chamber of flowing through from oil outlet out.Rotor adopts brush and commutator to commutate, and the fuel pump of prior art is only applicable to the oil-fired system of no corrosion.But along with being on the rise of global energy crisis, the exploitation of new energy is day by day urgent.Methyl alcohol has its irreplaceable market prospects because of characteristics such as its cost are low, the source wide, manufacture is easy, yet methyl alcohol is because the formic acid that oxidation produces is corrosive to metallic material sections such as iron, tin, aluminium, copper, zinc, electric fuel punp for prior art, the erosion produced will be aggravated the wearing and tearing of the pump housing, the ion in the partial corrosion thing also can be adsorbed on carbon brush, cause carbon brush and commutator bad connection, the commutation difficulty waits series of problems, thereby has reduced oil fuel pump performance and life-span.
The model utility content
The purpose of this utility model overcomes the deficiencies in the prior art exactly, and a kind of brushless methanol fuel pump that is applicable to methanol fuel, long service life is provided.
To achieve these goals, technical solution of the present utility model is such: brushless methanol fuel pump, comprise the rear end cover assembly, stator, rotor, the pump housing, the pump core, pump cover and shell, rotor and pump core are in transmission connection, the pump core is placed in the pump chamber consisted of the pump housing and pump cover, between rotor and stator, form rotor chamber, shell is the rear end cover assembly, stator, the pump housing and pump cover are fixed together, pump cover is provided with filler opening, the rear end cover assembly is provided with oil outlet, fuel oil enters from filler opening, flow through after rotor chamber from oil outlet out, adopt the brushless electronic commutator, described brushless electronic commutator comprises control panel, protecting jacket and cover plate, described control panel is packaged in the seal chamber consisted of protecting jacket and cover plate, described rotor carries out corrosion resistant encapsulation process with the surface that stator contacts with fuel oil.
The beneficial effects of the utility model are: for the severe corrosive of methyl alcohol, the utility model adopts the brushless electronic commutator, and corrosion resistant encapsulation process is carried out in the surface that control panel, rotor and stator contact with fuel oil, effectively prevent methanol fuel oil and above-mentioned parts generation chemical reaction, thereby guaranteed the performance and used life of methanol fuel pump.
