Description
Technical field
The utility model belongs to laboratory equipment technical field, relates in particular to a kind of water circulation vavuum pump.
Background technology
Water circulation vavuum pump is called water-ring vacuum pump, and it includes the parts such as impeller, the pump housing, suction and discharge disk；Impeller is inclined
Feel at ease in the pump housing, when the impeller is rotated, the water into the pump housing throws to surrounding by impeller, and is formed under the influence of centrifugal force
One equal thickness closing water ring similar to pump chamber shape.Now, a crescent sky is formd between impeller hub and water ring
Between, and the space is divided into several small chambers equal with lobe numbers by impeller.When 180 ° before impeller rotation, the appearance of small chamber
Product is gradually changed from small to big, and pressure constantly reduces, and is communicated with the air entry on suction and discharge disk, when the pressure in small cavity space is low
In the pressure taken out in container, according to gas pressure intensity equilibrium principle, the gas taken out constantly is drawn into small chamber.When air-breathing is completed
When completely cut off with air entry, the volume of small chamber is gradually reduced, and pressure constantly increases, when the gas of compression reaches pressure at expulsion,
From auxiliary exhaust valve exhaust.During the continuously running of pump, air-breathing, compression, exhaust process are constantly carried out, so as to reach
The purpose of continuous air extraction.Water circulation vavuum pump because its can aspirate and compress with corrosivity, it is inflammable, medium and testing
It is widely used in room.The dirt that existing water circulation vavuum pump adds up after a period of time is run in the pump housing can be to pumping effect
Have a negative impact, it is necessary to often carry out dismounting cleaning.The inconvenience that causes to use and efficiency it is low.Therefore, how to develop
A kind of new water circulation vavuum pump, it can avoid accumulation dirt occur in pump body, frequency is changed clothes in the dismounting for reducing the pump housing,
To improve operating efficiency.It is the direction that those skilled in the art need to study.
Utility model content
The utility model provides a kind of water circulation vavuum pump, can reduce caused noise in the process of running, lifting
The comfortableness of lab assistant at work.
The concrete technical scheme that it is used is as follows：
A kind of water circulation vavuum pump, including：The pump housing and gas-filtering device；Air entry and exhaust are provided with the top of the pump housing
Mouth, inside are provided with chamber；It is eccentrically mounted in the chamber to have provided with impeller；The gas-filtering device is used for being inhaled by air entry
The air-flow entered in the pump housing is filtered.
By using this technical scheme：Gas-filtering device is set to carry out the air for entering the pump housing by air entry
Filter, the speed of accumulation dirt in the pump housing is reduced, improve the operating efficiency of water circulation vavuum pump.
Preferably, in above-mentioned water circulation vavuum pump：The gas-filtering device includes screen pack；The screen pack installation
On the outside of air entry.It is further preferred that the screen pack is demountable structure.
By using this technical scheme：Filtering dust is carried out with the gas of the pump housing of the screen pack to being entered by air entry.
The screen pack can carry out dismounting and change in water circulation vavuum pump working condition, without close down vavuum pump influence test into
Journey.
It is further preferred that in above-mentioned water circulation vavuum pump：The gas-filtering device also includes activated carbon adsorption layer, described
Activated carbon adsorption layer is installed on pump body, between air entry and chamber.
By using this technical scheme：Further adsorbed using activated carbon adsorption layer and be arranged at screen pack on the outside of air entry
The little particle dust that can not be adsorbed.
It may further be preferable that in above-mentioned water circulation vavuum pump：Also include differential pressure inductor, the differential pressure inductor installation
In on activated carbon adsorption layer.
By using this technical scheme：With the air pressure value difference of differential pressure inductor sensing activated carbon adsorption layer both sides, when this
Numerical value illustrates that activated carbon adsorption layer reaches capacity less than threshold value, dismounting and change activated carbon must be avoided to block influence air-breathing effect in time
Fruit.
It is even furthermore preferable that in above-mentioned water circulation vavuum pump：Also include warning device, the warning device is according to difference
The feedback signal of inductor is pressed to send alarm signal.
By using this technical scheme：Initiative alarming is realized with warning device, staff without observing differential pressure frequently
Sensor data, reduce the working strength of staff.
It is even furthermore preferable that in above-mentioned water circulation vavuum pump：The warning device is buzzer.
Compared with prior art, the utility model is simple in construction, easily prepared.It can avoid accumulating in pump body
Dirt, the dismounting for reducing the pump housing change clothes frequency, improve operating efficiency.
Brief description of the drawings
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of the utility model embodiment 1.
Each reference and component names corresponding relation are as follows：
1st, the pump housing；2nd, impeller；4th, differential pressure inductor；5th, warning device；11st, air entry；12nd, exhaust outlet；13rd, chamber；31、
Screen pack.
Embodiment
In order to illustrate more clearly of the technical solution of the utility model, the utility model is made into one below in conjunction with accompanying drawing
Step description.
It is the structure of embodiment 1 of the present utility model as shown in Figure 1：
A kind of water circulation vavuum pump, including：The pump housing 1, impeller 2, gas-filtering device, differential pressure inductor 4 and warning device
5。
Wherein：The top of the pump housing 1 is provided with air entry 11 and exhaust outlet 12, inside are provided with chamber 13；The impeller 2 is eccentric
In installation and chamber 12.Screen pack 31 and activated carbon adsorption layer of the gas-filtering device including demountable structure, it is installed on
On air entry 11, the air-flow for being sucked by air entry 11 in the pump housing 1 is filtered.Specifically, the screen pack 31 is installed
In the outside of air entry 11.The activated carbon adsorption layer is installed on inside the pump housing 1 and between air entry 11 and chamber 13.Institute
Differential pressure inductor 4 is stated to be installed on activated carbon adsorption layer.The differential pressure inductor 5 uses buzzer, according to differential pressure inductor 4
Feedback signal sends alarm signal.
In practice, pass through being implemented in combination with to entering the pump housing 1 by air entry 11 for screen pack 31 and activated carbon adsorption layer 32
Air-flow is filtered.Its reason is：The suspension of the simple smaller particle that can not be filtered out by screen pack 31 in air-flow, and
If using activated carbon adsorption layer merely, need often to carry out dismounting and change to activated carbon adsorption layer, cause the drop of conventional efficient
It is low.
