Description
Technical field
The invention belongs to vacuum pump technology field, and in particular to a kind of oily ring vacuum pumps improved structure.
Background technology
Oily ring vacuum pumps are a kind of oil sealing side valve type pumps, can be evacuated to below 1.33Pa vacuum, it is adaptable to each
The product for having condition of high vacuum degree requirement is planted, is the domestic superior first choice of vavuum pump industry.However, it is when in use
Still suffer from some problems；First, oily ring vacuum pumps are by entering gas tank air-breathing, due on air inlet jar structure
It is unreasonable, the gas that vacuum pumping is entered contains more impurity, thus increase vavuum pump parts it
Between abrasion, reduce pump service life；2nd, oily ring vacuum pumps are exhaust tank by gs-oil separator
Exhaust, the quality of its discharge gas does not meet the requirement of low-carbon environment-friendly still.It is therefore desirable to propose to improve.
The content of the invention
Present invention solves the technical problem that：A kind of oily ring vacuum pumps improved structure is provided, by air inlet
Install media filtration buffer unit in tank additional, improve the medium aspirated into vavuum pump, reduce zero, vavuum pump
Friction between part, extends its service life, by installing current stabilization filter additional in exhaust tank, makes true
The medium of empty pump discharge is effectively purified, and is conducive to environmental protection.
The technical solution adopted by the present invention：Oily ring vacuum pumps improved structure, has into gas tank and exhaust tank,
It is described enter gas tank connected by suction line with vavuum pump, the exhaust tank passes through gas exhaust piping and vavuum pump
Connection, it is described enter gas tank inner top be provided with the top of media filtration buffer unit, the exhaust tank and be provided with standpipe,
The standpipe bottom is provided with current stabilization filter, and the exhaust tank bottom is provided with oily refluxing opening.
Wherein, the media filtration buffer unit includes cleaner and cleaner fixed mount, the cleaner
It is fixed on by cleaner fixed mount into gas tank internal upper part, the cleaner bottom passes through bend pipe and instrumentation tubes
Road is connected.
Further, the current stabilization filter includes the multiple filtration net being parallel to each other, the multilayer mistake
Filter screen is by being fixedly welded on standpipe bottom.
Further, the multiple filtration net is made of steel plate.
The advantage of the present invention compared with prior art：
1st, entering in gas tank to install additional media filtration buffer unit, the medium into vavuum pump passes through media filtration
Improvement is purified after cleaner buffering filtering in buffer unit, reduces zero, the vavuum pump that impurity is caused
Friction between part, extends service life of vacuum pump；
2nd, the multiple filtration net installed additional in exhaust tank in current stabilization filter, current stabilization filter makes vacuum
The medium of pump discharge is effectively purified, and is met low-carbon environment-friendly requirement, is conducive to environmental protection；
3rd, by setting oily refluxing opening in exhaust tank bottom, the oil of separation in exhaust tank is made to flow back and recycle,
Reduce and waste, it is cost-effective.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
1 embodiments of the invention are described below in conjunction with the accompanying drawings.
Oily ring vacuum pumps improved structure, as shown in figure 1, have into gas tank 1 and exhaust tank 2, it is described enter
Gas tank 1 is connected by suction line 4 with vavuum pump 3, and the exhaust tank 2 is by gas exhaust piping 5 and very
Empty pump 3 is connected, it is described enter the inner top of gas tank 1 be provided with media filtration buffer unit, specifically, being given an account of
Matter filtering buffer unit includes cleaner 7 and cleaner fixed mount 6, and the cleaner 7 is solid by cleaner
Determine frame 6 to be fixed on into the internal upper part of gas tank 1, the bottom of cleaner 7 is connected by bend pipe 8 and working line
Connect；When vavuum pump 3 works, the medium into vavuum pump 3 passes through the filtering in media filtration buffer unit
Improvement is purified after the buffering filtering of device 7, reduces the friction between each parts of vavuum pump that impurity is caused,
Extend the service life of vavuum pump 3.The top of exhaust tank 2 is provided with standpipe 9, and the bottom of standpipe 9 is provided with
Current stabilization filter, specifically, the current stabilization filter includes the multiple filtration net 10 being parallel to each other,
The multiple filtration net 10 is by being fixedly welded on the bottom of standpipe 9, it is preferred that the multiple filtration net 10
It is made of steel plate；The medium that multiple filtration net 10 in current stabilization filter discharges vavuum pump 3 is obtained
Effectively purification, meets low-carbon environment-friendly requirement, is conducive to environmental protection.The bottom of exhaust tank 2 is provided with oil
The oil of separation flows back and recycled in refluxing opening 11, exhaust tank 2, reduces and wastes, cost-effective.
Above-described embodiment, simply presently preferred embodiments of the present invention, not for limiting the scope of the present invention,
Therefore all equivalence changes done with content described in the claims in the present invention, all should be included in right of the present invention will
Within the scope of asking.
