Abstract
A kind of Jing Yin infusion pump.Mainly solve existing infusion pump need install by-passing valve, it is not only complicated, install trouble, and manufacturing cost it is high the problem of.It is characterized in that：The pump head intracavitary is additionally provided with the backflow runner for the shaping that caves inward, and its two ends corresponds to fuel feed hole and oil outlet respectively.It the advantage is that and use above scheme, when there is closing rifle or outlet obstruction, fluid, so as to realize the voluntarily circulation of fluid, so as to ensure that cavity pressure is normal, can not result in the damage to rotor or motor in backflow runner backflow；Compared with existing infusion pump, by-passing valve is eliminated, structure is simpler, easier for installation, reduces manufacturing cost.
Description
Technical field
The utility model is related to a kind of pump, specifically related to a kind of Jing Yin infusion pump.
Background technology
Chinese utility model patent（CN202017618U）A kind of Multi-angle DC petrol-feed pump is disclosed, two oilings are set
Mouthful and two oil-outs, multiple operating positions can be adapted to and used, then in oil suction chamber and gone out between oil pocket by placement pressure
Port valve, when closing rifle or outlet obstruction occur, pressure can exceed permissible value, so that by-passing valve is opened, realize the backflow of oil,
Ensure intracavitary normal pressure.
But installation by-passing valve is not only complicated, trouble is installed, and manufacturing cost is high.
Utility model content
In order to overcome the shortcomings of background technology, the utility model provides a kind of Jing Yin infusion pump, and solving existing infusion pump needs
By-passing valve is installed, it is not only complicated, install trouble, and manufacturing cost it is high the problem of.
The technical scheme that the utility model is used：A kind of Jing Yin infusion pump, including pump head, the pump housing, the pump head it is interior
Chamber is separated into pump head chamber, oil suction chamber, goes out oil pocket；Connected between the pump head chamber and oil suction chamber by fuel feed hole, with go out oil pocket it
Between connected by oil outlet；The snout cavity provided with least two connect oil inlet pipe oil inlet, it is described go out oil pocket be provided with least 2
The oil-out of individual connection flowline；Motor is set in the pump housing, and motor drive connection rotor, the pump housing is connected with pump head,
The rotor is placed in pump head intracavitary；The pump head intracavitary is additionally provided with the backflow runner for the shaping that caves inward, and its two ends is right respectively
Answer fuel feed hole and oil outlet.
The backflow runner is in circular arc.
The oil inlet sets 2, and the oil-out sets 2.
The center line of two oil inlets is arranged in a mutually vertical manner；The center line of two oil-outs is mutually perpendicular to set
Put.
The area of the oil outlet is more than the area of fuel feed hole.
The beneficial effects of the utility model are：Using above scheme, when there is closing rifle or outlet obstruction, fluid can
In backflow runner backflow, so as to realize the voluntarily circulation of fluid, so as to ensure that cavity pressure is normal, do not result in rotor or
The damage of motor；Compared with existing infusion pump, by-passing valve is eliminated, structure is simpler, easier for installation, reduce manufacture
Cost.

Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As illustrated, a kind of Jing Yin infusion pump, including pump head 1, the pump housing 2, the inner chamber of the pump head 1 is separated into pump head chamber
11st, oil suction chamber 12, go out oil pocket 13；Connected between the pump head chamber 11 and oil suction chamber 12 by fuel feed hole 14, with go out oil pocket 13 it
Between connected by oil outlet 15；Motor is set in the pump housing 2, and motor drive connection rotor 3, the pump housing 2 connects with pump head 1
Connect, the rotor 3 is placed in pump head chamber 11；Oil inlet 121 of the snout cavity 12 provided with 2 connection oil inlet pipes, it is described fuel-displaced
Oil-out 131 of the chamber 13 provided with 2 connection flowlines；The backflow runner for the shaping that caves inward is additionally provided with the pump head chamber 11
16, and its two ends corresponds to fuel feed hole 14 and oil outlet 15 respectively.
Oil in snout cavity 12 enters pump head chamber 11 by fuel feed hole 14, and passes through under the driving of rotor 3 oil outlet 15
Into oil pocket 13 is gone out, so as to realize oiling work；When closing rifle or outlet is blocked, cause fluid at oil outlet 15 without
Method is entered oil outlet 15 and flowed out, and now can just realize and flow back along backflow runner 16, realize that oil circulation flows, so as to ensure
Cavity pressure is normal, does not result in the damage to rotor 3 or motor；And compared with existing infusion pump, by-passing valve is eliminated,
Structure is simpler, easier for installation, reduces manufacturing cost.
Wherein, the backflow runner 16 is in circular arc so that fluid backflow flow direction is with rotor rotation direction on the contrary, being recycled back to
Flow effect more preferable.
In addition, snout cavity 12 is provided with 2 oil inlets 121, it is described go out oil pocket 13 provided with 2 oil-outs 131, can be adapted to many
The use of individual operating position, user, which uses, more to be facilitated, and adds flow, reduces noise, power needed for motor is smaller.
Further, the center line of two oil inlets 121 is arranged in a mutually vertical manner；In two oil-outs 131
Heart line is arranged in a mutually vertical manner, more reasonable structure, it is adaptable to use industry.
Certainly, to be not limited to 2 or 3 settings more for the quantity of oil inlet 121 and oil-out 131.
As illustrated, the area of the oil outlet 15 be more than fuel feed hole 14 area, the flow velocity of fluid faster, using effect
More preferably.
Embodiment is not construed as the limitation to utility model, but any based on spiritual improvements introduced of the present utility model,
All should be within protection domain of the present utility model.
