Abstract
The utility model discloses an electronic fuel pump of detachable, owing to connect through the detachable mode between its end cover that produces oil, oil feed end cover and the casing, therefore can take out the intraware of electronic fuel pump through simple operation, and be convenient for change and maintain the intraware of electronic fuel pump, can effectively reduce the maintenance cost.
Description
Technical field
This utility model relate to a kind of dismountable electric fuel punp.
Background technology
Electric fuel punp is one of basic composition of EFI fuel injection system, and effect is that fuel oil is transported in fuel feed pump after sucking-off pressurization from fuel tank, and certain fuel pressure is set up in fuel pressure regulator cooperation.Electric fuel punp generally comprises housing, fuel-displaced end cap, oil-feed end cap and intraware.Its intraware of electric fuel punp on the market is packaged in enclosure interior by fuel-displaced end cap and oil-feed end cap, it is difficult to dismounting.Owing to electric fuel punp belongs to consumable accessory, needing when its intraware goes wrong to change whole electric fuel punp, maintenance cost is higher.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of dismountable electric fuel punp, its simple in construction, it is possible to changes its intraware by dismounting electric fuel punp, reduces maintenance cost.
For achieving the above object, this utility model provides a kind of dismountable electric fuel punp, including housing, fuel-displaced end cap, oil-feed end cap and intraware, the most fuel-displaced end cap and oil-feed end cap are connected to the two ends of housing, intraware is arranged at the inside of housing, fuel-displaced end cap includes the top being placed in hull outside and the bottom being flush-mounted in shell inner hole, the bottom of fuel-displaced end cap has an annular projection, the endoporus of housing upper end is provided with the annular projection with fuel-displaced end cap and coordinates the hook groove of setting-in, the edge of housing upper end bends inwards and forms the parcel to annular projection, oil-feed end cap is threaded connection with the lower end of housing.
As further improvement of the utility model, described oil-feed end cap includes the top being placed in shell inner hole and is placed in the bottom of hull outside, the top of oil-feed end cap is threadingly attached in the endoporus of housing lower end, and the outer contour shape of the bottom of oil-feed end cap is suitable with the outer contour shape of described housing.Using technique scheme, make structure of the present utility model simpler, integraty is strong, and profile is the most attractive in appearance.
As further improvement of the utility model, on the outer peripheral face on the top of described oil-feed end cap and it is respectively provided with the annular recess of embedded sealing ring on the annular projection of described fuel-displaced end cap.The setting of sealing ring is prevented from fuel oil and leaks from housing, thus adds electric fuel punp safety.
As further improvement of the utility model, the outer peripheral face of the bottom of described oil-feed end cap is evenly equipped with anti-skidding convex tendon.Anti-skidding convex tendon can increase frictional force, it is simple to maintainer is dismantled.
The beneficial effects of the utility model are: dismountable electric fuel punp that this utility model provides, due to its fuel-displaced end cap, connected by dismountable mode between oil-feed end cap and housing, therefore, it is possible to taken out the intraware of electric fuel punp by simple operations, it is easy to the intraware of electric fuel punp is replaced and keeps in repair, it is possible to effectively reduce maintenance cost.
Accompanying drawing explanation
Fig. 1 is generalized section of the present utility model.
Detailed description of the invention
nullThe embodiment of dismountable electric fuel punp of the present utility model is as shown in Figure 1: include housing 1、Fuel-displaced end cap 2、Oil-feed end cap 3 and intraware，The most fuel-displaced end cap 2 and oil-feed end cap 3 are connected to the two ends of housing 1，Intraware is arranged at the inside of housing 1，It is characterized in that: fuel-displaced end cap 2 includes the top being placed in outside housing 1 and the bottom being flush-mounted in housing 1 endoporus，The bottom of fuel-displaced end cap 2 has an annular projection 21，The endoporus of housing 1 upper end is provided with the annular projection 21 with fuel-displaced end cap 2 and coordinates the hook groove 11 of setting-in，The internal diameter outline of described housing 1 is less than the external diameter of annular projection 21，When installing fuel-displaced end cap 2，The fuel-displaced end cap 2 endoporus from housing 1 lower end is sent into，Hook groove 11 can be installed on time at the hook groove 11 of dislocation housing 1，The edge of housing 1 upper end bends inwards and forms the parcel to annular projection 21，Oil-feed end cap 3 is threaded connection with the lower end of housing 1.
In the present embodiment, described oil-feed end cap 3 includes the top being placed in housing 1 endoporus and is placed in the bottom outside housing 1, the top of oil-feed end cap 3 is threadingly attached in the endoporus of housing 1 lower end, and the outer contour shape of the bottom of oil-feed end cap 3 is suitable with the outer contour shape of described housing 1.
In the present embodiment, the annular recess of embedded sealing ring 4 on the outer peripheral face on the top of described oil-feed end cap 3 and it is respectively provided with on the annular projection 21 of described fuel-displaced end cap 2.
In the present embodiment, the outer peripheral face of the bottom of described oil-feed end cap 3 is evenly equipped with anti-skidding convex tendon.
Dismountable electric fuel punp that this utility model provides is when carrying out demolition and maintenance, first by oil-feed end cap 3 from housing 1 lower end rotating separation, then take out the intraware being placed within housing 1, finally fuel-displaced end cap 2 is pushed from housing 1 upper end to lower end and go out, the parts of electric fuel punp can be changed at any time, thus effectively reduce the maintenance cost of electric fuel punp.
Above example, the simply one of this utility model preferably specific embodiment, the usual variations and alternatives that those skilled in the art are carried out in the range of technical solutions of the utility model are included in protection domain of the present utility model.
