Abstract
The utility model discloses a kind of injection pump installation, the fuel filter (6) of impurity is exported mounted on fuel oil jet pump (2) wherein in filter fuel, fuel filter bypass flap (5) is installed in parallel with fuel filter (6), it is opened when fuel filter (6) blocks, fuel oil is supplied to engine, the fuel filter whether detection fuel filter (6) blocks blocks visualizer (7) and is installed in parallel with fuel filter (6), fuel filter pre-clogging pressure switch (4) is installed in parallel with fuel filter (6), for detecting the pre-clogging degree of fuel filter (6), the whether too low fuel pressure low switch (3) of detection fuel pressure is installed on fuel oil injection pump discharge.The injection pump installation of the utility model both has Gernral Check-up monitoring function, it again can be when filter core blocks, it prevents engine from the injection pump installation of parking accident occurs due to not having fuel oil, improves the safety of engine fuel oil system, ensure engine fuel oil system normal work.
Description
Technical field
The utility model belongs to engine fuel oil system field, is related to a kind of injection with filtering and health diagnosis function
Pump installation.
Background technology
Traditional jet pump is at most provided with coarse strainer in the sucking head piece of jet pump, can not realize the fine mistake of fuel oil
It filters and the fuel pressure in jet pump cannot be monitored.In use, when fuel pressure is excessively high, Fuel System can be caused
Each component of uniting damages and leakage.In addition, when filter core blocks, due to not having fuel oil parking accident can occur for engine.
Utility model content
In view of the above situation of the prior art, the purpose of this utility model is to provide a kind of with both with Gernral Check-up prison
Brake, and can prevent engine from the injection pump installation of parking accident occurs due to not having fuel oil when filter core blocks, improve
The safety of engine fuel oil system ensures engine fuel oil system normal work.
The above-mentioned purpose of the purpose of this utility model is realized using following technical scheme：
A kind of injection pump installation with filtering and health diagnosis function, including dynamic valve, fuel oil jet pump, fuel oil pressure
Power low switch, fuel filter pre-clogging pressure switch, fuel filter bypass flap, fuel filter and fuel filter block visualizer.
The workflow of fuel oil jet pump is provided by the gear oil feed pump of engine fuel oil system, by dynamic valve by work
Flowing pressure increases, and suck stream connects fuel tank by pipeline, and workflow and suck stream mix and in fuel oil jet pump through runner
Outflow, the fuel filter are mounted on fuel oil injection pump discharge, for the impurity in filter fuel, prevent the impurity in fuel oil from damaging
Other parts in engine fuel oil system, the fuel filter bypass flap are installed in parallel with fuel filter, act as working as fuel oil
When filter blocks, fuel filter bypass flap is opened to engine and supplies fuel oil, prevents engine due to not having fuel oil parking thing
Therefore the fuel filter blocks visualizer and is installed in parallel with fuel filter, and for detecting whether fuel filter blocks, the fuel filter
Pre-clogging pressure switch is installed in parallel with fuel filter, for detecting the pre-clogging degree of fuel filter, the fuel pressure low switch
Fuel oil injection pump discharge is installed on, it is whether too low for detecting fuel pressure, send out alarm signal when fuel pressure is too low.
Further, the filtering accuracy of fuel filter is micron order, to better ensure that the cleaning that fuel oil is supplied to engine
Degree.
Inner height is integrated with dynamic valve, fuel oil jet pump, combustion to the injection pump installation of the utility model in a limited space
Oil pressure low switch, fuel filter pre-clogging pressure switch, fuel filter bypass flap, fuel filter, fuel filter block visualizer
Etc. fuel systems attachment, it is small, it is light-weight, it is easy to maintain, and realize filtering and the health diagnosis function of fuel system, can
It prevents engine from parking accident occurs due to not having fuel oil, improves the safety of engine fuel oil system, ensure engine combustion
Oil system works normally.
Description of the drawings
Fig. 1 is showing for the operation principle for the injection pump installation with filtering and health diagnosis function for representing the utility model
Figure.
Specific embodiment
Below in conjunction with the accompanying drawings, the injection pump installation with filtering and health diagnosis function of the utility model is said
It is bright.
Fig. 1 is showing for the operation principle for the injection pump installation with filtering and health diagnosis function for representing the utility model
Figure.As shown in the figure, the injection pump installation of the utility model draws including highly integrated dynamic valve 1, fuel oil in a limited space
Pump 2, fuel pressure low switch 3, fuel filter pre-clogging pressure switch 4, fuel filter bypass flap 5, fuel filter 6 and fuel filter is penetrated to block up
Fill in visualizer 7.
The workflow of the fuel oil jet pump 2 is provided by the gear oil feed pump of engine fuel oil system, passes through dynamic valve 1
Work flowing pressure is increased, suck stream is mixed simultaneously by pipeline connection fuel tank, workflow and suck stream in fuel oil jet pump 2
It is flowed out through runner, the fuel filter 6 is mounted on fuel oil injection pump discharge, for the impurity in filter fuel, prevents in fuel oil
Other parts in impurity damage engine fuel oil system, the filtering accuracy of fuel filter 6 is preferably micron order, to ensure to hair
Motivation supplies the cleannes of fuel oil.The fuel filter bypass flap 5 is installed in parallel with fuel filter 6, act as blocking when fuel filter 6
When, fuel filter bypass flap 5 is opened to engine and supplies fuel oil, prevents engine due to not having fuel oil parking accident.Institute
It states fuel filter blocking visualizer 7 to be installed in parallel with fuel filter 6, for detecting whether fuel filter 6 blocks and need replacing.Separately
Outside, the fuel filter pre-clogging pressure switch 4 is installed in parallel with fuel filter 6, for detecting the pre-clogging degree of fuel filter 6.This
Outside, whether the fuel pressure low switch 3 is installed on fuel oil injection pump discharge, too low for detecting fuel pressure, when fuel oil pressure
When power is too low, alarm signal is sent out.
Claims (2)
1. a kind of injection pump installation with filtering and health diagnosis function, including dynamic valve (1), fuel oil jet pump (2), combustion
