Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
The utility model provides all compound two-purpose pumps of a kind of air chamber conversion, includes the pump housing, is equipped with main shaft in the pump housing, main shaft is arranged on the pump housing by bearing, be provided with crankshaft gear by gear ring in the pump housing, be provided with at least one pair of cylinder assembly outside main shaft, cylinder assembly is positioned at the pump housing, cylinder assembly includes cylinder body, cylinder body one end is provided with sealing plate, is provided with piston in cylinder body, and piston is provided with piston rod, be provided with bent axle in crankshaft gear, bent axle is connected with piston rod; The pump housing is provided with at least one intakeport and at least one relief opening, sealing plate inwall is provided with inner gas port, sealing plate outer wall is provided with outside air port, sealing plate be provided with sealing seat between outside air port and the intakeport of the pump housing, sealing plate be also provided with sealing seat between outside air port and relief opening; Form air chamber in cylinder body, between the intakeport on inner gas port and the pump housing, form air vent, between the relief opening on inner gas port and the pump housing, form air outlet flue; Outside air port and the joint of sealing seat are provided with that cylinder type is fixedly connected with, circular cone self contained is connected or planar structure formula connects.
Under the effect of power outside, main shaft drives at least one pair of cylinder assembly be located at outside main shaft to rotate, and under the transmission of crankshaft gear and gear ring, bent axle is connected with piston rod, and therefore just drive piston moves.When block-head cylinder assembly rotates, the intakeport towards air chamber enters the seal area of sealing seat, and air-breathing is carried out in the front end that the piston in cylinder body is in cylinder body, and the end that the piston in adjacent cylinder block is in cylinder body is exhausted, and piston starts reversing motion simultaneously.In like manner, along with continuing of rotating, outside air port on the intakeport and sealing plate outer wall of air chamber is connected, piston also carries out air-breathing thereupon, when piston runs to fixing stroke, the outside air port towards air chamber enters next seal area, under the same principle of seal area, relief opening on the outside air port and sealing seat of air chamber is connected, and the air that piston starts sucking from suction port discharges air chamber by relief opening.All cylinder bodies are all synchronous operation when working, and under mutual alternate run, realize air and enter row's separation, cycle operation, reach straight and inhale and in line effect.Namely in the course of the work, under mutually alternately changing towards the ventilating hole of air chamber and the suction and exhaust ports of the pump housing, the air of piston is made to achieve unidirectional movement at fixing area operation, reach the effect that the straight suction of air is in line, leading to the outside air port of air chamber and the joint of sealing seat, the cooperation corresponding to circular cone self contained structure of cylinder fixed can be adopted to reach air-proof condition, with bearing concentric running, also the corresponding cooperation of planar configuration can be adopted to reach air-proof condition, realize zero friction, make product durable.
Namely the utility model (1) dual-purposely can carry out air vacuum and air compressing; (2) motor frequency conversion can be coordinated to arrange air pressure needed for work; (3) sustainable use; (4) friction can not be increased because of pressure under great dynamics vacuum, better in the sealing of leading to the outside air port of air chamber and the suction and exhaust ports place of the pump housing.
