Defeated pump, is widely used in the industries such as metallurgy, chemical industry, food, electronics plated film, and existing gas transfer pump has the following disadvantages：1.
Assembling process complexity is cumbersome, and the possibility there are gas leakage is easy in structure；Working barrel usually have and only there are one, if damage device
It will be stopped, it is therefore proposed that a kind of vacuum pump to solve the above problems is actually necessary.
Invention content
The present invention is at least one defect (deficiency) overcome described in the above-mentioned prior art, provides a kind of vacuum pump.
In order to solve the above technical problems, technical scheme is as follows：A kind of vacuum pump, including：Outer housing, peace
Supply unit inside outer housing further includes：Main working barrel, subtask pump and air transporting arrangement, the gas conveying
Device one end is connect with main working barrel, and the other end is connected with subtask pump, and the vacuum pump is novel in design, carries major-minor working barrel,
When one of damage, another can also carry out replacement work, ensure device normal work.
Further, the main working barrel includes armature spindle, rotor, interstitital texture part, and the rotor is mounted on armature spindle
End position, armature spindle are electrically connected with supply unit, and interstitital texture part is fixed on armature spindle, and interstitital texture part is a kind of epoxy
Resin is covered on armature spindle comprehensively, the phenomenon that effectively gas capable of being avoided to overflow outward, cause gas leakage.
Further, the subtask pump includes diaphragm, inlet valve and air bleeding valve, and described inlet valve one end connects with diaphragm
It connects, the other end is connect with air bleeding valve, the cooperating of inlet valve and air bleeding valve, and the presence of air bleeding valve can prevent the gas in exhaust area
Body is back in the enclosure space of vacuum pump.
Further, the supply unit further includes the first driving unit and the second driving unit, and first driving is single
First to be connect with main working barrel, the second driving unit is connected with subtask pump, and major-minor working barrel all uses independent driving device, greatly
The big working efficiency for improving device and the adaptibility to response for facing emergency case.
Further, it is additionally provided with flow-stop valve on the air transporting arrangement, can effectively prevent gas backstreaming to main work
In pump.
Further, vacuum degree display table, the vacuum of the real-time supervisory device of the person of being conveniently operated are additionally provided on the outer housing
Degree.
Further, it is additionally provided with exhaust hole on the rotor.
Compared with prior art, the advantageous effect of technical solution of the present invention is：
(1) vacuum pump disclosed by the invention, it is novel in design, major-minor working barrel is carried, when one of damage, separately
One can also carry out replacement work, ensure device normal work.
(2) vacuum pump disclosed by the invention, interstitital texture part are a kind of epoxy resin, are covered in armature spindle comprehensively
On, the phenomenon that effectively gas capable of being avoided to overflow outward, cause gas leakage.
(3) vacuum pump disclosed by the invention, it is simple in structure, it is easy to maintenance.
(4) vacuum pump disclosed by the invention, low production cost are suitble to mass production.
