Time causes pump to fail, and influences the flight safety of aircraft.
Prior art is by improving the boost pressure of hydraulic pump inlet, increase hydraulic pump to the solution of above mentioned problem
Imbibition pipeline latus rectum, the mode such as imbibition pipeline, control system fluid temperature that air enters hydraulic pump is reduced, to ensure hydraulic pressure
Good imbibition ability during pump work.But for aircraft system, these solutions suffer from the constraint of objective condition
And limitation, it is impossible to optimum design geometry desired by designer is fully achieved.Such as, increase hydraulic pump imbibition pipeline latus rectum by
The constraint of the factors such as tube material specification limitation, improves the boost pressure of hydraulic pump inlet by factors such as auxiliary products, expenses
Limitation etc..
The content of the invention
To overcome the defect that above-mentioned prior art is present, the invention provides a kind of aircraft hydraulic pumps air pocket discharger,
It is connected between liquid reserve tank and hydraulic pump by imbibition pipeline, the air pocket discharger includes compensator, and imbibition pipeline is upward
Direction be provided with branch line, compensator is connected with the branch line, i.e. the branch point for leading to hydraulic pump of imbibition pipeline
With lead to compensator branch point be same point, liquid medium this branch point punishment be two-way, wherein lead up to all the way mend
Device is repaid, hydraulic pump is led on another road；
The installation site of compensator is higher than imbibition pipeline, so that it is cavity that bubble, which can enter inside compensator, compensator,
The cavity wall is evenly equipped with some thorn-likes projections, for the bubble in liquid medium, is provided with and atmosphere at the top of compensator
Exhaust outlet, for discharge pricked a bubble in compensator after the air that produces.
It is preferred that, compensator is a spheroid, and the cavity is in spherical, and spherical is the most fast most comprehensive shape pricked a bubble
Shape.
It is preferred that, thorn-like projection is cone.
It is preferred that, the plug for being used for controlling it to be opened and closed is housed on exhaust outlet.
A kind of aircraft hydraulic pumps air pocket discharger that the present invention is provided, on imbibition pipeline being connected with inside is covered with thorn-like
Raised compensator, makes the liquid with bubble be punctured due to Action of Gravity Field automatically into compensator, and by thorn-like projection
Bubble, it is to avoid press pump produces cavitation, while the apparatus structure is simple, it is easy to accomplish.

As label represent same or similar element or the element with same or like function.Described embodiment is the present invention
A part of embodiment, rather than whole embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to uses
It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiment in the present invention, ordinary skill people
The every other embodiment that member is obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
In the description of the invention, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " is based on accompanying drawing institutes
The orientation or position relationship shown, is for only for ease of the description present invention and simplifies description, rather than indicate or imply meaning
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to present invention guarantor
Protect the limitation of scope.
A kind of aircraft hydraulic pumps air pocket discharger that the present invention is provided is illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, the invention provides a kind of aircraft hydraulic pumps air pocket discharger, between liquid reserve tank 1 and hydraulic pump 3
It is connected by imbibition pipeline 2, the air pocket discharger includes compensator 4, imbibition pipeline 2 is provided with branched pipe in upwardly direction
Road, compensator 4 is connected with the branch line, i.e., the branch point for leading to hydraulic pump 3 of imbibition pipeline 2 and lead to compensator 4
Branch point be same point, liquid medium is two-way in the punishment of this branch point, leads to compensator 4 all the way wherein upward, another
Hydraulic pump 3 is led on road；
The installation site of compensator 4 is higher than imbibition pipeline 2, so that bubble can enter compensator 4.
As shown in Fig. 2 compensator 4 is a hollow ball, it is spherical cavity that it is internal, and the cavity wall is evenly equipped with some
In the thorn-like projection 5 of cone, for the bubble in liquid medium, the top of compensator 4 is provided with the exhaust outlet 6 with atmosphere,
For discharge pricked a bubble in compensator 4 after the air that produces, have the plug for closing it on exhaust outlet 6.
Below by the embodiment using fluid as liquid medium, the present invention is described in further detail.
Specific embodiment：
When before the start-up operation of aircraft hydraulic pumps air pocket discharger, the plug on confirmation exhaust outlet 6 is turned off, ambient atmos
Compensator 4 can not be entered by exhaust outlet 6；
After starter, hydraulic pump 3 can extract the fluid in liquid reserve tank 1 by imbibition pipeline 2, now imbibition pipeline 2, benefit
Repaying the air in device 4 can all be extruded by fluid and be discharged by hydraulic pump 3, therefore in the normal work of hydraulic pump 3 and pipette
When not having dissociated air in road 2, fluid is filled with compensator 4；
When occurring the fluid with bubble in imbibition pipeline 2, because bubble is considerably lighter than fluid, therefore in imbibition pipeline 2,
Fluid with bubble can be floated over above, when it reaches branch line, and common fluid can be down into hydraulic pump 3, and with gas
The fluid of bubble is entered in compensator 4, while the fluid in compensator 4 also can be fast because therefore lighter in weight can float up
Speed is filled automatically into the entrance of hydraulic pump 3, keeps the continuity of the entrance fuel feeding of hydraulic pump 3, and avoids hydraulic pump 3 from sucking
Air produces cavitation, and the bubble in compensator 4 can be punctured by the thorn-like projection 5 of cone, then be floated on compensator 4
Side.
When the air in compensator 4 need too much exhaust when, the plug on exhaust outlet 6 can slightly be opened a bit, by
In the effect of oil pressure, the air for floating over the top of compensator 4 can be squeezed out rapidly, when having the fluid to emerge at exhaust outlet 6, be said
Air in bright compensator 4 is all discharged, and can now be closed plug and be sealed compensator 4.
The aircraft hydraulic pumps air pocket discharger that the present invention is provided comes into operation on aircraft, and effect is very
It is good, it is to avoid the generation of cavitation.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
