Brief description of the drawings
In order to illustrate more clearly of the technical scheme in the utility model embodiment, below will be to needed for embodiment description
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
Other accompanying drawings are obtained, wherein：
Fig. 1 is the structural representation of the utility model online vacuum ultrasonic sound intensity testing device one preferred embodiment.
Specific embodiment
The technical scheme in the utility model embodiment will be clearly and completely described below, it is clear that described
Embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the implementation in the utility model
Example, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to
The scope of the utility model protection.
Fig. 1 is referred to, the utility model embodiment includes：
A kind of online vacuum ultrasonic sound intensity testing device, including：Sound intensity testing ultrasonic cleaner 1, the cleaning
The outlet of groove 1 is connected with vacuum barrel 2.
Vavuum pump 3 and pulsating pump 4 are connected with vacuum barrel 2.
Vavuum pump 3 is used to maintain the vacuum state in vacuum barrel 2 so that vacuum barrel 2 is under negative pressure from ultrasonic cleaner 1
Interior introducing liquid.The vacuum barrel 2 is provided with vacuum meter.It is easy to observe the vacuum values in vacuum barrel 2.
Pulsating pump 4 is auto-suction pump 4, and the pulsating pump 4 is provided with water inlet and delivery port, water inlet and vacuum barrel 2
Connection, delivery port is exported to ultrasonic cleaner 1 by pipeline.
The rinse bath 1 exports and the first regulating valve 5 is provided with and vacuum barrel 2 between, and vacuum barrel 2 is provided with the second regulating valve 6,
The 3rd regulating valve 7 is provided between water inlet and vacuum barrel 2.
High level sensor 2-1 and low liquid level sensor 2-2 is provided with the vacuum barrel 2.The high level sensor 2-
1st, low liquid level sensor 2-2, the first regulating valve 5, the second regulating valve 6 and the 3rd regulating valve 7 are electrically connected with control device.
By adjusting the first regulating valve 5 and the 3rd regulating valve 7 so that the balance of the liquid in bucket of vacuum barrel 2.That is negative pressure of vacuum
The fluid flow of introducing keeps balance with the liquid that pulsating pump 4 is extracted out.
High level sensor 2-1 is the suction liquid of vavuum pump 3, when high level sensing when preventing liquid overfill in vacuum barrel 2
Device 2-1 senses water level, then by feedback of the information to control device, control device control vavuum pump 3 is stopped.
The effect of low liquid level sensor 2-2 is protection pulsating pump 4, when low liquid level sensor sense 2-2 should arrive water level, Ji Jiangxin
Breath feeds back to control device, and control device control water suction water pump is stopped.
The utility model reduces the liquid bubble amount in ultrasonic cleaner, improves the accuracy of sound intensity testing value,
Improve reference value.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
The technical field of pass, is similarly included in scope of patent protection of the present utility model.
