Abstract
The utility model discloses a kind of double outlet piezoelectric pumps of single-chamber with bluff body, the pump housing, sealing ring, piezoelectric vibrator and pump cover including having class sub warhead arc bluff body.The both ends of the pump housing are equipped with one-pipe inlet and twin flue liquid outlet, 5 class sub warhead arc bluff body structures are arranged in the inner cavity of the pump housing, it is arranged in pump chamber with two, three arrangement modes, its sub warhead is towards one-pipe inlet, annular seal groove is arranged in pump chamber top side end face, sealing ring is placed in the seal groove, places piezoelectric vibrator above the sealing ring, the pump housing and pump cover pass through adhesive sealing.This pump has many advantages, such as that resistance flowing effect is good, and output flow is big, has a good application prospect in the fields such as agricultural greenhouse nursery droplet and spray.
Description
Technical field
The utility model relates to a kind of double outlet piezoelectric pumps of single-chamber with bluff body, belong to field of fluid machinery.
Background technique
Valveless piezoelectric pump now is all the purpose realizing reduction by bluff body and flowing back, however most of valveless pressures
Electric pump reduction reflux effect be not it is too ideal, this mainly has with the structure of Valveless piezoelectric pump bluff body and arrangement mode
It closes, so needing to be improved for the design of Valveless piezoelectric pump bluff body.
Utility model content
The utility model current Valveless piezoelectric pump there are aiming at the problem that, propose a kind of there is that structure is simple, effectively reduces
The big Valveless piezoelectric pump of reflux, output flow.
The utility model discloses a kind of double outlet piezoelectric pumps of the single-chamber with fluid, including the pump housing, piezoelectric vibrator, sealing ring
And pump cover.
The pump housing is equipped with one-pipe inlet and twin flue liquid outlet, and the internal diameter of the one-pipe inlet of the pump housing is big
In the internal diameter of twin flue liquid outlet, be conducive to increase output flow.
5 class sub warhead arc bluff bodys are set in the pump housing, 2 this structures are placed at one-pipe inlet, it is two-tube
3 this structures are placed at road liquid outlet, sub warhead head is towards one-pipe inlet direction.
Annular seal groove is arranged in pump housing top side end face, places sealing ring, the sealing in the annular seal groove
Place piezoelectric vibrator in the top of circle.
Pump cover (4) center opens up seal groove (4-1) and sealing ring (2) and compresses piezoelectric vibrator (2) jointly.
The beneficial effects of the utility model are: increasing output flow using one-pipe inlet and twin flue liquid outlet；
The arc bluff body of inside setting bullet-shaped, can effectively reduce reflux, be conducive to improve pumpability.
Detailed description of the invention
Fig. 1 show the overall schematic of the utility model.
Fig. 2 show the pump housing schematic diagram of the utility model.
Fig. 3 show the superstructure schematic diagram of the utility model.
Specific embodiment
In order to further appreciate that the structure, feature and other purposes of the utility model, now in conjunction with appended preferred embodiment,
Detailed description are as follows, and illustrated preferred embodiment is merely to illustrate the technical solution of the utility model, and non-limiting practical
It is novel.
Specific embodiment of the present utility model is as follows:
As shown in Figures 1 to 3, the double outlet piezoelectric pumps of the single-chamber with bluff body include the pump housing (1), it is piezoelectric vibrator (2), close
Seal (3) and pump cover (4).
One-pipe inlet (1-1) and twin flue liquid outlet (1-2), one-pipe inlet is respectively set in the pump housing both ends
The internal diameter of (1-1) is greater than the internal diameter of twin flue liquid outlet (1-2), can achieve the purpose of flow increase.
5 class sub warhead arc bluff bodys (1-3) are set inside the pump housing (1), are placed at one-pipe inlet (1-1)
2 this structures, place 3 this structures at twin flue liquid outlet (1-2), sub warhead head towards one-pipe inlet direction,
It can achieve the purpose for effectively reducing reflux.
Annular seal groove is arranged in the pump housing (1) the top side end face, and sealing ring is placed in seal groove, is placed above sealing ring
Piezoelectric vibrator can preferably fix piezoelectric vibrator.
The pump housing (1) and pump cover (4) are attached by gluing, have preferable sealing effect.
The pump cover (4) opens up seal groove (4-1) and sealing ring (2) and compresses piezoelectric vibrator (2) jointly.
The course of work of the utility model can be divided into the following two course of work:
When applying electric signal to piezoelectric vibrator (2), piezoelectric vibrator (2) will receive the excitation of electric signal, and generate vibration
Deformation, when piezoelectric vibrator (2) arches upward upwards, liquid from one-pipe inlet (1-1) and twin flue liquid outlet (1-2) simultaneously
Into the amount of liquid for entering cavity from one-pipe inlet (1-1) is greater than the liquid for entering pump chamber from twin flue liquid outlet (1-2)
Amount；
When piezoelectric vibrator (2) is bent downwardly deformation, liquid is by one-pipe inlet (1-1) and twin flue liquid outlet (1-
2) it being discharged simultaneously, the amount of liquid exported from twin flue liquid outlet (1-2) is greater than the amount of liquid that one-pipe inlet (1-1) is exported,
Macroscopically realize the one-way flow of liquid.
