Description
Affiliated technical field
The utility model relates to a kind of air compressor, refers in particular to a kind of single screw air compressor.
Background technique
Single screw air compressor is that the Frenchman is in the seventies invention in last century, it is compared with double-screw compressor with reciprocating-piston compressor, have simple in structure, characteristics such as running is reliable, in light weight, the life-span is long, noise is low, manufacturing saving of labor, be used widely at present.But this technology also exposes its deficiency simultaneously, and is not high enough such as air pressure, and Fraquent start influenced machine working life etc. when the air container volume was too small.For these reasons, be necessary for the high pressure compressed gas field a kind of better single screw air compressor is provided.
The model utility content
The purpose of this utility model is to provide a kind of coaxial binodal single screw type tri-star wheel air compressor, and it was both efficient, environmental protection, and structure is simple again.
For achieving the above object, the solution that the utility model is taked is: a kind of coaxial binodal single screw type tri-star wheel air compressor, comprise a housing, the driving of one group of drive screw and control gear, one group of intelligence is regulated the automatic controller of stable gas pressure, a deaerator that is used for Oil-gas Separation and lubricant oil is provided, place main shaft in the housing, the driving of drive screw and control gear drive main shaft, have suction port in the housing, air outlet and valve, the screw rod that has coaxial binodal screw thread on the main shaft, first segment screw rod and two star-wheel engagements, the second joint screw rod and a star-wheel engagement, constitute screw rod star-wheel pair with the star-wheel of screw engages, in housing, have joint between joint and the joint and add a grade gas transmission road.
When the driving that starts one group of drive screw and control gear and one group of intelligence are regulated the automatic controller of stable gas pressure, the driving of drive screw and control gear drive one and are placed on an interior secondary running of screw rod star-wheel that constitutes with star-wheel screw engages of housing that has many group air inlet/outlets and valve, after the air in the coaxial first segment screw rod backlash is by the star-wheel compression, joint pressurization gas transmission road enters the second coaxial joint screw rod backlash, be engaged simultaneously the star-wheel compression of the second joint screw rod running once more, thereby produce pressurized gas.In addition, when the air supply system internal air pressure reaches certain level, regulate the first segment in the automatic controller dynamic and intelligent control screw rod star-wheel pair of stable gas pressure or the fuel feeding situation of second joint by intelligence and reach the stable of system's air pressure, also avoided the infringement of big starting current that main frequent motor starting brings simultaneously power supply system.The utility model is applicable to that industrial pneumatic equipment air feed, railway locomotive, steamer, chemical industry etc. need efficient compressed-air actuated place, and particularly some needs the compressed-air actuated place of ultrahigh pressure, and some has the place of specific (special) requirements to the air feed stable gas pressure.
The utility model is simple in structure, easily manufactured, stable, noise is low, long service life, can not only be efficiently, continue, stably provide pressurized air for all kinds of pneumatic equipments, and can stablize the ultrahigh pressure air that provides general compressor not provide, and has the function that the intelligent control regulating solar term are pressed.
Description of drawings
Fig. 1 is present embodiment main shaft and the secondary engagement situation of screw rod star-wheel schematic representation.
Fig. 2 is the structural representation of present embodiment.
Among Fig. 1: 1, first segment screw rod, 2, star-wheel, 3, main shaft, 4, the second joint screw rod, 5, star-wheel, 6, suction port, 7, joint adds a grade gas transmission road, 8, housing, 9, the air outlet.
Embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1 and Fig. 2, a kind of coaxial binodal single screw type tri-star wheel air compressor, comprise a housing 8, the driving of one group of drive screw and control gear, one group of intelligence is regulated the automatic controller of stable gas pressure, a deaerator that is used for Oil-gas Separation and lubricant oil is provided, place main shaft 3 in the housing 8, the driving of drive screw and control gear drive main shaft 3, have suction port 6 in the housing 8, air outlet 9 and valve, the screw rod that has coaxial binodal screw thread on the main shaft 3, first segment screw rod 1 and two star-wheel 2 engagements, the second joint screw rod 4 and star-wheel 5 engagements, star-wheel 2 with screw engages, 5 constitute screw rod star-wheel pair, have joint between joint and the joint and add a grade gas transmission road 7 in housing 8.
Housing 8 is used to seal the secondary and merogenesis gas flow modulation of screw rod star-wheel.But two joint hand of spiral same distribution also can positive and negatively be symmetrically distributed.Two star-wheels 2 are as the criterion with first segment screw rod 1 axis and are symmetrical distribution, and a star-wheel 5 is as the criterion with the second joint screw rod, 4 axis and is arranged on the second joint screw rod, 4 one sides.Concavo-convex spiral shell in the screw rod comprises various line styles and various pitch and gradient.But two joint screw rod paired runnings also can add level pressurization operation, include oil and add the level operation and do not have oil and add level operation (oilless compressor).The automatic controller that intelligence is regulated stable gas pressure has intelligent regulatory function, under main motor normal operation situation, provides stable air feed air pressure by the adjusting first segment or the second joint screw rod star-wheel subtask state.
Referring to Fig. 1, air pressure adjustment function of the present utility model is achieved in that after star-wheel 2 compressions of a pair of cooperation first segment screw rod 1 that the air-flow in first segment screw rod 1 backlash is engaged, air-flow enters the backlash of the second joint screw rod 4, be engaged simultaneously star-wheel 5 compressions that cooperate the second joint screw rod 4 of the second joint screw rod, 4 runnings once more, air-flow extrudes from the outlet side of the second joint screw rod 4, thereby produces pressurized gas; After system's air pressure reaches certain level, the intelligent control system of the automatic controller of intelligence adjusting stable gas pressure will be closed the oil gas control valve of the second joint screw rod 4, reducing system's air demand, otherwise then open air inlet/outlet, thereby reach stable system air pressure and do not close the purpose of main motor.
The utlity model has the air pressure height, flow is big, revolution is low, noise is low, stable, the life-span is long etc. Advantage.
