Abstract
The utility model is related to a kind of urea pump sensor unit of stabilized structure.The sensor unit of urea pump is planted, includes liquid level sensor and temperature sensor, it is characterised in that：The temperature sensor is moulded in injection molding body, and the liquid level sensor is arranged in sensor stand, and the injection molding body is together with sensor stand injection, and injection molding body is located at sensor stand side.The sensor unit of this urea pump, due to structure-integrated, with easy for installation, occupies little space, the advantages of stabilized structure.
Description
Technical field
The utility model is related to a kind of urea pump, and in particular to a kind of sensor unit of urea pump.
Background technology
Urea for vehicle decomposes ammonification at a certain temperature, can be to nitrogen oxides（NOX）SCR is carried out, will
NO in waste gasXIt is reduced into N2And H2O, so as to reach the purpose of energy-saving and emission-reduction.Because the environmental protection department of various countries is proposed into one
Step reduces the oxynitrides pollution of diesel emission, is commonly called as the Europe IV standard, engine manufacturer begins to use SCR system（Select
Selecting property catalyst reduction system）To reach the requirement of environmental administration.SCR system includes urea tank and SCR catalytic reactors.SCR systems
The running of system is：When finding to have nitrogen oxides in blast pipe, the urea liquid in urea pump extracted urea tank, and convey
To injection unit, urea for vehicle is sprayed by injection unit and in SCR catalytic reactors redox reaction occurs for nitrogen oxides,
Generate free of contamination nitrogen and water vapour discharge.Liquid level sensor and temperature sensor are installed, at present general urine in urea pump
The liquid level sensor and temperature sensor of plain pump are all independently installed by support, and urea pump is installed onboard and run with car
Winnow with a dustpan, sensor is easy to therefore be affected.
The content of the invention
In view of the deficiency that prior art is present, a kind of urea pump sensor of the utility model innovation there is provided stabilized structure
Assembly.The sensor unit of urea pump is planted, includes liquid level sensor and temperature sensor, it is characterised in that：The temperature is passed
Sensor is moulded in injection molding body, and the liquid level sensor is arranged in sensor stand, and the injection molding body is noted with sensor stand
Mould together, and injection molding body is located at sensor stand side.
The sensor stand upper end has to be molded with outstanding edge, the sensor stand upper end and edge
Seal injection molding body.
The sensor unit of a kind of urea pump provided according to the utility model, due to structure-integrated, with installation side
Just, occupy little space, the advantages of stabilized structure.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the sectional view of the utility model upper end.
Embodiment
As shown in figure 1, the sensor unit of the urea pump includes liquid level sensor 2 and temperature sensor 3, TEMP
Device 3 is moulded in injection molding body 4, and liquid level sensor 2 is arranged in sensor stand 1, and injection molding body 4 is molded with sensor stand 1
Together, and injection molding body 4 be located at the side of sensor stand 1.So liquid level sensor 2 is integrated in one with temperature sensor 3
On sensor stand 1, this spline structure is more consolidated, and installs also more convenient, and overall space-consuming is also small.
As shown in Fig. 2 the upper end of sensor stand 1 is provided with a variety of electronic components 7, these electronic components 7 are by electric wire 6 with passing
Sensor is connected, in order to effectively be sealed to these electronic components, the utility model the upper end of sensor stand 1 be provided with to
The edge 10 of outer protrusion, and it is molded with the upper end of sensor stand 1 and edge 10 sealing injection molding body 5（Edge 10 contributes to close
Envelope injection molding body 5 forms full enclosed sealing）, this has sealing injection molding body 5 by the edge 10 of the upper end of sensor stand 1, electronic component 7
And part electric wire 6 is all included, the structure type surrounded entirely is achieved in, so can prevent urea for vehicle from penetrating into well
Erode electronic component.
