Abstract
The utility model relates to a vacuum pressure combined gas pump, particularly to a self-lubrication vacuum pressure combined gas pump, which comprises a vacuum pressure regulating device, a gas intake port, a gas outtake port, a pump body, a rotor eccentrically disposed in the pump body, a revolution graphite sliding sheet disposed in a rotor longitudinal groove and capable of freely sliding in the radial direction, a motor driving device connected with one end of a rotor shaft, and a cooling system and a pump head assembly connected with the motor driving device. Since the revolution graphite sliding sheet is made from a graphite product material and has a self-lubricating action, the exhausted gas is pure, contains no any oil stain, and meets the requirements for the high-grade printing. The gas pump has the advantages of flexible gas intake and gas outtake, low temperature rise, low noise, pure gas and no pollution, and can be widely applied in the printing industry and also applied in industries such as packaging, cigarette making, dust collecting, grain process, environment protecting, woodworking machinery and the like.
Description
Technical field
The utility model relates to a kind of vacuum-pressure composite air pump, particularly relates to a kind of self-lubricating type vacuum-pressure composite air pump.
Background technique
Existing and the matching used air pump of printing press mostly is the ZYB vacuum-pressure composite air pump greatly, because this air pump is high speed rotating when work, slide plate is done in rotor and is produced friction when radially sliding, produce a large amount of heats thus, temperature between slide plate and the rotor will soon be risen to more than 400 ℃, and slide plate and rotor are overheated, cause rotor, slide plate to damage simultaneously, even burn-down of electric motor, for the proper functioning that guarantees air pump must adopt the oil lubrication device; But after air pump works long hours, even air pump has adopted oil and gas separating system, because gathering in the gas that has caused discharging of greasy dirt contains suitable greasy dirt particle, and the greasy dirt in the gas is fatal defective for printing, it will cause the serious distortion of printing color, it is irregular to paint, even causes scrapping of product.
Summary of the invention
Technical problem to be solved in the utility model is: solve existing vacuum-pressure composite air pump and adopt the oil lubrication device, the technical problem that contains the greasy dirt particle in the gas of discharging after air pump works long hours, the utility model provides a kind of self-lubricating vacuum pressure compound air pump, it need not to adopt other lubricating fitting, just can reach no matter air pump operating time length, its gas of discharging is pure, is not with any greasy dirt all the time, satisfies the requirement of high-grade printing.
The utility model is to solve above-mentioned technical problem by the following technical programs: a kind of self-lubricating vacuum pressure compound air pump, it comprises that vacuum pressure adjustment, air-breathing relief opening, the pump housing, off-centre are disposed at rotor, the motor drive unit, the cooling system that links to each other with motor drive unit, the pump head parts that link to each other with rotor shaft one end in the pump housing and place the revolution graphite slide plate that can radially be free to slide in the rotor cannelure.
The utility model adopts SLALOM chip mechanical structure, do rotation motion by rotor and change swept volume, it is element volume, thereby change gas pressure, the rotor eccentricity of sliding vane gas machinery is configured in the pump housing, during the rotor rotation, slide plate is subjected to centrifugal action and presses to pump housing inwall, cylinder inner wall, rotor outer surface and two adjacent slide plates constitute element volume, and rotor rotates a circle, and each element volume will become big gradually by minimum value, up to maximum value, diminished gradually by maximum value, get back to minimum value, rotor rotates a circle, element volume is air-breathing successively, compression, processes such as exhaust, because the revolution slide plate adopts the graphite product material, played the effect of selflubricating, and the selflubricating formula vacuum-pressure composite air pump that the utility model provides has suction, blow flexibly, temperature rise is low, noise is little, and the pure advantage such as pollution-free of gas has solved the situation that high-grade printing machinery relies on import.
The selflubricating formula vacuum-pressure composite air pump that the utility model provides also can be applicable to industries such as packing, cigarette, dedusting, grain processing, environmental protection, woodworking machinery except that being widely used in printing industry.

Embodiment
In conjunction with the accompanying drawings, the utility model provides following embodiment:
Self-lubricating vacuum pressure compound air pump as depicted in figs. 1 and 2, comprise vacuum pressure adjustment 1, air-breathing relief opening 2, the pump housing 3, off-centre is disposed at the rotor 5 in the pump housing 3, place the revolution graphite slide plate 4 that can radially be free to slide in rotor 5 cannelures, the motor drive unit 7 that links to each other with rotor 5 rotating shafts one end, cooling system 6 that links to each other with motor drive unit 7 and pump head parts 8, when rotor 5 rotations, revolution graphite slide plate 4 is subjected to centrifugal action and presses to the pump housing 3 inwalls, cylinder inner wall, rotor 5 outer surfaces and two adjacent slide plates constitute element volume, rotor rotates a circle, and each element volume will be become greatly gradually by minimum value, up to maximum value, diminish gradually by maximum value again, get back to minimum value, rotor rotates a circle, and element volume is air-breathing successively, compression, processes such as exhaust, because the revolution slide plate adopts the graphite product material, played the effect of selflubricating, the gas of discharge is pure pollution-free, is not with any greasy dirt all the time.
