Abstract
The invention relates to a mini vacuum pump which comprises an electrical machine and a pump body, wherein an air inlet, an air outlet and a pump cavity for communicating the air inlet with the air outlet are arranged on the pump body, and routes of the air inlet and the air outlet are sequentially connected with a filter and a silencer in series. The mini vacuum pump has the advantages that 1) the mini vacuum pump is provided with the filter and the silencer, the air firstly flows through the filter when the air enters into and leaves away from the pump cavity, so that the pump cavity internally keeps at a good work environment always, and then the air flows through the silencer, so that the generated noise when the air flows is reduced, therefore, the work environment of a worker is improved; 2) on the basis of 1), the mini vacuum pump is respectively provided with a hole at the positions where the filter and the silencer are arranged, so that the filter and the silencer can be replaced through the holes when the filter and the silencer are damaged, and the maintenance efficiency is improved since the damaged filter and silencer can be changed through the holes when the filter and the silencer are damaged; and 3) the mini vacuum pump is provided with an air inlet pipe and an air outlet pipe, wherein the air inlet pipe and the air outlet pipe can be turned on so as to be taken as a temporary air circulation channel if necessary and can be turned off after the filter and the silencer are maintained.
Description
Technical field
The present invention relates to a kind of minipump, belong to the pump technical field.
Background technique
Minipump is widely used in gas sampling, gas circulation, vacuum suction, accelerated filtration, vacuum automobile power-assisted or the like occasion as power plant, has obtained in fields such as medical treatment, health, scientific research, environmental protection using widely.
Minipump because will suck air, exhausting air, can send bigger sound during air flow in the course of the work; Influence working environment, impurity such as particulate are arranged simultaneously, in the air after impurity is inhaled into vacuum pump; Can produce bump with the parts in the vacuum pump, quicken the damage of vacuum pump, the increase of pump service time while; Impurity in the pump is cumulative, also can influence the service behaviour of vacuum pump.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to make that the vacuum pump service behaviour is improved, operating life is improved.
Technological scheme of the present invention is: the present invention includes motor, the pump housing, the pump housing is provided with the pump chamber of suction port, air outlet and connection suction port, air outlet, is connected with filter and baffler on the path of suction port, air outlet successively.
The part that the vacuum pump place is positioned at filter and baffler is offered porose, and the position in hole is provided with the cover plate that the hole is covered.
The suction port place is provided with and filter, baffler and the suction tude that connects, and the place, air outlet is provided with and filter, baffler and the steam outlet pipe that connects, is respectively equipped with switch on suction tude and the steam outlet pipe.
Advantage of the present invention is: 1) the present invention is provided with filter and baffler, when air gets into and leaves pump chamber, earlier through filter; With airborne impurity absorption; Make in the pump chamber can be in good working environment all the time, through behind the filter, the air baffler of flowing through again; The sound that produces when reducing air flow improves staff's working environment; 2) 1) the basis on, the present invention establishes the hole at the position of filter, baffler, like this when filter, when baffler is damaged; Need be with the pump integral demounting; Only need the filter that damages, baffler to be changed, improved maintenance efficiency, reduced maintenance cost through the hole; 3) for vacuum pump when filter, baffler damage can work on, ad hoc suction tude, steam outlet pipe when needing to use, are opened switch, as interim air communication channel, after device to be filtered, baffler maintenance are good, close suction tude and steam outlet pipe.
Description of drawings
Fig. 1 is a structural representation of the present invention
1 is that motor, 2 is that the pump housing, 3 is that suction port, 4 is that filter, 5 is that baffler, 6 is that suction tude, 7 is that pump chamber, 8 is that steam outlet pipe, 9 is the air outlet among the figure.
Embodiment
The present invention drives the pump housing 2 runnings by motor 1, and the to-and-fro motion through film in the pump chamber 7 to the air compression in it, stretching, reaches the work purpose of pump.
The present invention is provided with at suction port 3 places and filter 4, baffler 5 and the suction tude 6 that connects, and 9 places establish and filter 4, baffler 5 and the steam outlet pipe 8 that connects in the air outlet.
The present invention is positioned at filter 4 at the pump housing 2, the hole is established at baffler 5 positions, establishes the cover plate that the hole is covered at the corresponding position in hole.
