Abstract
The present invention relates to kind of coaxial multisection worm type air compressor. One worm driving and controlling unit drives one coaxial multisection screw inside one casing with air inlets and valves and one worm pairs comprising planetary gears meshing the screw. The air in the first screw tooth space of the coaxial screw is first compressed by the planetary gear and then further compressed by the planetary gear fitting the second section of the screw to produce high pressure air. In addition, after the air supplying system reaches certain pressure level, the oil feeding status of the multisection worm pair is controlled intelligently to reach stable air pressure while avoiding the frequent start of the motor to protect the power supply system. The present invention is suitable for use in special fields needing high efficiency compressed air, such as locomotive, ship, chemical industry, etc.
Description
Patent of the present invention relates to a kind of coaxial more piece Worm type air compressor, one group of driving and control gear that drives worm screw, driving one is placed on and has the worm gear pair running that the screw rod of coaxial more piece screw thread and star-wheel that screw engages is closed in many assembly constitute by one 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, enter 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).In addition, when the air supply system internal air pressure reaches certain level, fuel feeding situation by the joint in the dynamic and intelligent control more piece worm gear pair or several joints reaches the stable of system's air pressure, has also avoided the infringement to power supply system of big starting current that main frequent motor starting brings simultaneously.Patent of the present invention 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.
Single Worm type air compressor is that the Frenchman invents at the seventies, 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, obtained civilian general application 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 air compressor is provided, it is high-efficiency environment friendly both, and structure is simple again.
The main purpose of patent of the present invention provides a kind of coaxial more piece Worm type air compressor, it 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 the ultrahigh pressure air that provides general compressor not provide can be provided, and the function of intelligent control regulating solar term pressure.
For reaching above purpose, the coaxial more piece Worm type air compressor of patent of the present invention comprises:
Screw rod with coaxial more piece screw thread;
The worm gear pair of the star-wheel formation of screw engages is closed in many assembly, and two engagements of every joint screw rod cooperation star-wheels, constitutes worm gear pair with screw rod;
One group of driving and control gear that drives worm gear pair;
One group of intelligence is regulated the automatic controller of stable gas pressure;
A housing that is used to seal worm gear pair that has many group air valve doors;
A deaerator that is used for Oil-gas Separation and lubricant oil is provided.
The air pressure adjustment function of patent of the present invention is to realize that like this (with two joints is example, other are analogized): after a pair of star-wheel (2) compression that the air-flow (4) in first segment screw rod (1) backlash coaxial among Fig. 1 is engaged, air-flow (4) enters the backlash of the second coaxial joint screw rod (5), be engaged simultaneously a pair of star-wheel (6) compression of second joint screw rod (5) running once more, air-flow (4) extrudes from the outlet side of the second joint screw rod (5), thereby produces pressurized gas; After system's air pressure reaches certain level, intelligent control system will be closed the oil gas control valve of the second joint screw rod (5), 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 advantage of patent of the present invention has: the air pressure height, flow is big, revolution is low, noise is low, stable, the life-span is long etc.
The concrete structure of patent of the present invention provides with following accompanying drawing:
Accompanying drawing is the structural representation of this air compressor.
Among Fig. 1, (1) coaxial first segment screw rod; (2) star-wheel of cooperation first segment screw rod; (3) screw rod main shaft; (4) air-flow; (5) the coaxial second joint screw rod; (6) star-wheel of the cooperation second joint screw rod.
Fig. 2 is the schematic representation of three joints.(1) suction port; (2) screw rod; (3) star-wheel; (4) joint adds a grade gas transmission road; (5) housing; (6) air outlet; (7) main shaft; (8) A1, A2, A3 three joints add a grade worm screw.
Claims (6)
1, a kind of coaxial more piece Worm type air compressor comprises: a cover has the worm gear pair that the screw rod of coaxial more piece screw thread and star-wheel that screw engages is closed in many assembly constitute by one; One group of driving and control gear that drives worm screw; A housing that has many group air inlet/outlets and valve is used to seal worm gear pair and merogenesis gas flow modulation.
2, the described coaxial more piece Worm type air compressor of claim 1, generally its coaxial worm has 2 joints to 8 joints, but each saves screw rod direction same distribution and also can positive and negatively be symmetrically distributed.
3, the described coaxial more piece Worm type air compressor of claim 1, every joint screw rod cooperate the running of two engagement star-wheels, and two star-wheels are as the criterion with the screw rod axis and are symmetrical distribution.
4, the described coaxial more piece Worm type air compressor of claim 1, the concavo-convex spiral shell of the spiral shell wheel in its more piece worm gear pair comprises various line styles and various pitch and gradient.
5, the described coaxial more piece Worm type air compressor of claim 1, but its each joint paired running also can add level pressurization operation, include oil and add the level operation and do not have oil and add level operation (oilless compressor).
6, the described coaxial more piece Worm type air compressor of claim 1 has intelligent regulatory function, under main motor normal operation situation, by regulating certain joint or more piece worm gear pair working state provides stable air feed air pressure.
