Embodiment 1
Fig. 1 shows the structure diagram of methanol tolerant oil pump 10.
Methanol tolerant oil pump 10 works suitable for the pump oil of the alcohol-based fuels such as methanol, it includes fuel pump 101 and anode
Protection module 102.Fuel pump 101 is a kind of electrically driven (operated) oil pump, it is necessary to which accessing extraneous power supply could work.Fuel pump 101
Fuel is the alcohol-based fuels such as methanol, and the tie point of the electrode of fuel pump 101 and extraneous power supply is metal connection point, fuel pump 101
When surrounding is powered again there are substantial amounts of methanol, methanol and metal connection point, galvanic interaction occurs, more active metal connects
Contact loses electronics and is aoxidized, and electrochemical corrosion occurs so that the wiring point loose contact of fuel oil even disconnects, fuel pump
101 can not work normally.
Due to metal connection point occur electrochemical corrosion be anode occur oxidation reaction, for anode metal tie point
It is a kind of consumption so that anode metal tie point dissolves, and reduction reaction occurs for cathode, generally only serves the effect for transferring electronics.
By adding anodic protection module 102 so that the electronics that the anode metal connection of fuel pump 101 is pointed out was in
Surplus state effectively inhibits the activity of anode metal tie point, it is therefore prevented that the electrochemical corrosion of metal connection point, so that
The metal connection point for obtaining fuel pump 101 has anti-oxidant, corrosion resistant characteristic so that the fuel oil with anodic protection module 102
Pump 101 becomes methanol tolerant oil pump 10.
Anodic protection module 102 is DC power supply, using the output terminal of DC power supply as second plate 1021, arranged on combustion
The housing adjacent of oil pump 101 so that the electrode of fuel pump 101 nearby generates substantial amounts of electronics, so that 101 sun of fuel pump
The dissolving of pole metal connection point is suppressed, and corrosion rate reduces, and is protected the tie point of fuel pump 101, fuel pump
101 have double anode, and the speed of the electrochemical corrosion of 101 anode metal tie point of fuel pump greatly reduces.
Anodic protection is that protected anode metal tie point is connected with the anode of external dc power supply, is fired in alcohol radical
In material, anodic oxidation occurs for second plate 1021, so that being flooded with around the anode metal tie point of fuel pump 101
Surplus electronics so that the dissolving of the anode metal tie point of fuel pump 101 is suppressed, and corrosion rate reduces, so that positive
Pole metal connection point is protected.To anode metal tie point using anodic protection, the comprehensive of these metals can be not only controlled
Corrosion, and can prevent the local corrosions such as spot corrosion, stress-corrosion cracking, intercrystalline corrosion.
Simultaneously can coat packaging plastic at the anode metal tie point of fuel pump 101 so that anode metal tie point and
Air insulated reduces the activity of anode metal tie point.In a manner that anodic protection and coating protection are used in combination, only
Passivation is needed to cover not tight place, critical passivation current greatly reduces, and investment cost greatly reduces, and coats the sun of packaging plastic
The area of pole metal connection point greatly reduces, and is passivated again after activation also easily.
In the present embodiment, the input terminal of anodic protection module 102 is electrically connected with the positive and negative anodes of fuel pump 101.Anode is protected
Shield module 102 is connected on the positive and negative anodes of fuel pump 101 so that shares a power supply, the i.e. power supply of automobile with fuel pump 101.
As shown in Fig. 2, anodic protection module 102 is actually an amplifying circuit, the power supply of amplifying circuit is the 12V power supplys of automobile,
Into the effect for crossing amplifying circuit, the voltage of output terminal is 26V, increases voltage, reduces electric current.While electric current reduces,
The electrochemical corrosion of anode metal tie point and the output terminal of anodic protection module 102 also reduces.Directly by anode
Protection module 102 connects with the power supply of fuel pump 101, without separately connecing power supply so that the structure of methanol tolerant oil pump 10 more simplifies
With it is compact.
The positive and negative anodes junction of input terminal and fuel pump 101 has been respectively coated by heat-shrink tube 103.Heat-shrink tube 103 is a kind of spy
The polyolefin material heat-shrinkable tube of system, or EVA foam materials.Outer layer uses the cross-linked polyolefin material of high-quality softness
What material and internal layer hot melt adhesive Compound Machining formed, cladding material has the features such as insulation corrosion protection, wear-resisting, and internal layer has low melting point, waterproof
The advantages that sealing and high adhesiveness.By heat-shrink tube 103 by the positive and negative of the input terminal of anodic protection module 102 and fuel pump 101
The connection exposed section closing of pole, avoids the exposed generation chemical attack of tie point so that second plate 1021 and fuel pump 101
Anode metal tie point electric connection more stablize.Heat-shrink tube 103 is but also the positive and negative anodes and sun of fuel pump 101 simultaneously
The connection of the positive and negative anodes of pole protection module 102 is more firm, prevents from mutually loosening therebetween.
Second plate 1021 is fixed on by connector 104 on the housing of fuel pump 101, second plate 1021 and fuel pump
Insulating layer 105 is equipped between 101 housing, connector 104 is insulating part.It is by connector 104 that position free second is positive
Pole 1021 is fixed on the housing of fuel pump 101, so that the position of second plate 1021 is fixed, to prevent second plate
1021 generate electric connection with the housing of fuel pump 101, cause the housing of fuel pump 101 that electrochemical corrosion occurs when being powered,
Insulating layer 105 is thus added between the housing of fuel pump 101 and second plate 1021 so that mutually isolated therebetween.
