Description
Technical field:
The utility model relates to a kind of vacuum pump that is used for technologies such as vacuum filtration, vacuum feeding, vacuum outgas, vacuum evaporation, vacuum concentration and vacuum conditioning, is specifically related to a kind of novel direct connection vacuum pump.
Background technique:
Ring type vacuum pump (abbreviation water ring pump) is a kind of coarse vacuum pump, and its obtainable ultimate pressure is 2.66～9.31kPa for single-stage pump; For two-stage pump is 0.133～0.665kPa.Water ring pump also can be used as compressor, and it belongs to the compressor of low pressure, and its pressure range is (1～2) X105Pa manometer pressure (under given conditions).Water ring pump is in many manufacturing processs of industry such as oil, chemical industry, machinery, mine, light industry, papermaking, power, metallurgy, medicine and food and departments such as municipal administration and agricultural, as vacuum filtration, vacuum feeding, vacuum outgas, vacuum evaporation, vacuum concentration and vacuum conditioning etc., obtained using widely, because the process of water ring pump pressurized gas is an isothermal, so can extract inflammable, explosive gas, can extract dust-laden in addition, moisture gas, therefore, the application of water ring pump increases day by day.Present water ring pump is in ambient temperature 540 scopes, and suction port pressure is less than allowing long-term running continuously under the condition of 1.3X103 handkerchief, and pumped gas relative moisture should be driven gas ballast valve greater than 90% o'clock.But the continuous unimpeded atmosphere of its suction port must not turn round and surpassed one fen kind, so present water ring pump is suitable for to extract metal is not had corrosion, to pump oil chemical reaction, the gas that contains particle dust, and it is too high to contain oxygen, have volatile, poisonous gas.
The model utility content:
The purpose of this utility model provides a kind of novel direct connection vacuum pump, and it is simple in structure, and working time is longer, and is widely applicable.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it is to chew 1 by air inlet, filter screen 2, oil baffle 3, O-ring seals 4 is chewed in air inlet, blade spring 5, blade 6, rotor 7, pump body 8, fuel tank 9, exhaust valve plate 10 and pumping fluid 11 are formed, air inlet is chewed 1 and is fixedlyed connected with fuel tank 9, air inlet is chewed 1 lower end and is connected with pump body 8, filter screen 2 is arranged on air inlet and chews 1 inner upper end, oil baffle 3 is arranged on air inlet and chews 1 lower end, air inlet is chewed O-ring seals 4 and is arranged on air inlet and chews the outside, 1 lower end, exhaust valve plate 10 is arranged on the upper end of pump body 8, rotor 7 is arranged on the inboard of pump body 8, blade spring 5 is arranged in the middle of the blade 6, blade 6 is arranged in the middle of the rotor 7, pump body 8 is arranged on fuel tank 9 inside, is provided with pumping fluid 11 between pump body 8 and the fuel tank 9.
Rotor of the present utility model 7 is by eccentric being installed in the pump body 8, when rotor 7 rotations, enters around water in the pump body 8 thrown to by rotor 7, because action of centrifugal force, water has formed the water ring of the sealing of an equal thickness similar to pump body 8 cavity shapes.The upper inside surface of water ring is lucky and rotor 7 wheel hubs are tangent, and the lower inner surface of water ring just contacts with rotor 7 tops, and according to the gas pressure intensity principle for balance, the gas of being taken out constantly is drawn into loculus, is in breathing process this moment.When the pressure of gas during greater than drain pressure, compressed gas is discharged from from relief opening, in the continuous operation process of pump, is constantly carrying out air-breathing, compression, exhaust process, thereby reaches the purpose of continuous air extraction.
The utility model is simple in structure, and working time is longer, and is widely applicable.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
With reference to Fig. 1, this embodiment is by the following technical solutions: it is to chew 1 by air inlet, filter screen 2, oil baffle 3, O-ring seals 4 is chewed in air inlet, blade spring 5, blade 6, rotor 7, pump body 8, fuel tank 9, exhaust valve plate 10 and pumping fluid 11 are formed, air inlet is chewed 1 and is fixedlyed connected with fuel tank 9, air inlet is chewed 1 lower end and is connected with pump body 8, filter screen 2 is arranged on air inlet and chews 1 inner upper end, oil baffle 3 is arranged on air inlet and chews 1 lower end, air inlet is chewed O-ring seals 4 and is arranged on air inlet and chews the outside, 1 lower end, exhaust valve plate 10 is arranged on the upper end of pump body 8, rotor 7 is arranged on the inboard of pump body 8, blade spring 5 is arranged in the middle of the blade 6, blade 6 is arranged in the middle of the rotor 7, pump body 8 is arranged on fuel tank 9 inside, is provided with pumping fluid 11 between pump body 8 and the fuel tank 9.
The rotor 7 of this embodiment is by eccentric being installed in the pump body 8, when rotor 7 rotations, enters around water in the pump body 8 thrown to by rotor 7, because action of centrifugal force, water has formed the water ring of the sealing of an equal thickness similar to pump body 8 cavity shapes.The upper inside surface of water ring is lucky and rotor 7 wheel hubs are tangent, and the lower inner surface of water ring just contacts with rotor 7 tops, and according to the gas pressure intensity principle for balance, the gas of being taken out constantly is drawn into loculus, is in breathing process this moment.When the pressure of gas during greater than drain pressure, compressed gas is discharged from from relief opening, in the continuous operation process of pump, is constantly carrying out air-breathing, compression, exhaust process, thereby reaches the purpose of continuous air extraction.
This embodiment is simple in structure, and working time is longer, and is widely applicable.
