Description
One, affiliated technical field
The utility model relates to a kind of air compressor, refers in particular to a kind of screw air compressor.
Two, 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 screw air compressor is provided.
Three, model utility content
The purpose of this utility model is to provide a kind of coaxial ladder type more piece screw air compressor, its high-efficiency environment friendly, and structure is simple again, has to add the level effect, and can have multistage air pressure to select.
For achieving the above object, the solution that the utility model is taked is: a kind of coaxial ladder type more piece screw 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, has coaxial more piece thread screw on the main shaft, the star-wheel engagement of screw rod is closed in coaxial more piece thread screw and many assembly, the thread screw diameter increases by joint, the star-wheel diameter also increases by joint, the star-wheel that is closed screw engages by many assembly constitutes screw pair, has joint between joint and the joint and add a grade gas transmission road in housing.
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 having coaxial more piece thread screw and many assembly by and close the screw pair running that the star-wheel of screw engages constitutes in the housing that has many group air inlet/outlets and a 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.More piece is analogized.It has the level effect of adding, and can have multistage air pressure to select.In addition, when the air supply system internal air pressure reaches certain level, regulate the joint in the automatic controller dynamic and intelligent control more piece screw pair of stable gas pressure or the fuel feeding situation of several joints 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.Simultaneously, 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.
Four, description of drawings
Fig. 1 is present embodiment (coaxial ladder type two joint screw air compressors) main shaft and a screw pair engagement situation schematic representation.
Fig. 2 is the structural representation of present embodiment (coaxial ladder type two joint screw air compressors).
Among Fig. 1: 1, thread screw, 2, star-wheel, 3, main shaft, 4, air-flow, 5, thread screw, 6, star-wheel, 7, suction port, 8, joint adds a grade gas transmission road, 9, housing, 10, the air outlet, 11, main shaft.
Five, 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 ladder type more piece screw air compressor, comprise a housing 9, 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 11 in the housing 9, the driving of drive screw and control gear drive main shaft 11, have suction port 7 in the housing 9, air outlet 10 and valve, has coaxial more piece thread screw 1 on the main shaft 11,5, coaxial more piece thread screw 1,5 and many assembly close the star-wheel 2 of screw rod, 6 engagements, thread screw 1,5 diameters increase by joint, star- wheel 2,6 diameters also increase by joint, close the star-wheel 2 of screw engages by many assembly, 6 constitute screw pair, have joint between joint and the joint and add a grade gas transmission road 8 in housing 9.
Referring to Fig. 2, housing 9 is used to seal screw pair and merogenesis gas flow modulation.Coaxial more piece thread screw 1,5 has 2 joints to 3 joints, but each saves thread screw 1,5 direction same distribution and also can positive and negatively be symmetrically distributed.Every joint thread screw 1,5 cooperates two engagement star- wheel 2,6 runnings, and two star- wheels 2,6 are as the criterion with thread screw 1,5 axis and are symmetrical distribution.Concavo-convex spiral shell in the thread screw 1,5 comprises various line styles and various pitch and gradient.But each saves thread screw 1,5 paired runnings, also can add level pressurization operation, includes oil and adds 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, by regulating certain joint or more piece screw pair working state provides stable air feed air pressure.
Referring to Fig. 1 and Fig. 2, air pressure adjustment function of the present utility model is to realize that like this (with two joints is example, other are analogized): after star-wheel 2 compressions of a pair of cooperation first segment thread screw 1 that the air-flow 4 in first segment thread screw 1 backlash is engaged, air-flow 4 enters the backlash of the second joint thread screw 5, be engaged simultaneously star-wheel 6 compressions of a pair of cooperation second joint thread screw of the second joint thread screw, 5 runnings once more, air-flow 4 extrudes from the outlet side of the second joint thread screw 5, 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 thread screw 5, to reduce 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.
