In the prior art, the control mode that helical-lobe compressor adopts upper pressure limit limit switch control suction valve, diesel engine throttle to open or close fully basically.The aerodynamic pressure instability that this control mode provided, and suction valve, the frequent switch of diesel engine throttle cause the acute variation of operating mode, and the impact that is produced seriously influences the life-span of prime mover, compressor host.
The model utility summary of the invention
The utility model is exactly the deficiency in the background technique, provides an a kind of cover air compressor system that the demand of two kinds of pressure outputs is provided, and the two pressure output control systems of a kind of helical-lobe compressor of research and development.
In order to achieve the above object, the two pressure output control systems of the utility model helical-lobe compressor, comprise prime mover, barrel of oil and gas, compressor, prime mover clutch end is connected with the compressor power input end, compressor is provided with air inlet, compressor is communicated with barrel of oil and gas, barrel of oil and gas goes up A ' mouth with two-position three way magnetic valve I and is communicated with, two-position three way magnetic valve I is A upward, and " mouth is gone up B ' mouth or D ' mouth with two-position three way magnetic valve II respectively; servo cylinder is communicated with; two-position three way magnetic valve II goes up D, and " mouth is connected with high pressure modulating valve suction port, " mouthful be connected with low-pressure modulating valve suction port, the interior air valve that often drives into of air inlet is connected B on servo cylinder and the compressor.
For of the present utility model a kind of preferred, " passage is provided with silencing apparatus to the last A of two-position three way magnetic valve I between last B ' mouth of mouth and two-position three way magnetic valve II or D ' mouth, the servo cylinder.
For of the present utility model a kind of preferred, the connection of high pressure modulating valve air outlet is gone up C ' with two-position three way magnetic valve I respectively with low-pressure modulating valve air outlet and is communicated with.
For of the present utility model a kind of preferred, two-position three way magnetic valve I is A ' mouth and A upward " mouth is communicated with C ' mouth and C ", and mouth is communicated with, and two-position three way magnetic valve II goes up B ' mouth B, and " mouthful connection, " mouth is communicated with for D ' mouth and D.
The utility model is compared with background technique, have simple and practical, can be according to two kinds of forced air supplies, and air feed is stable, has prolonged the life-span of complete machine.
The utility model is elaborated with reference to accompanying drawing below in conjunction with embodiment.
Description of drawings
Fig. 1 is the structural representation of the two pressure output control systems of helical-lobe compressor.
Embodiment
Embodiment 1: with reference to Fig. 1.The two pressure output control systems of helical-lobe compressor, comprise prime mover 1, barrel of oil and gas 11, compressor 2, prime mover 1 clutch end is connected with compressor 11 power intakes, compressor 2 is provided with air inlet 3, compressor 11 is communicated with barrel of oil and gas 11, barrel of oil and gas 11 is communicated with A ' mouth on the two-position three way magnetic valve I 10, A on the two-position three way magnetic valve I 10 " mouth respectively with two-position three way magnetic valve II 7 on B ' mouth or D ' mouth; servo cylinder 8 connections; " mouth is connected with high pressure modulating valve 5 suction ports D on the two-position three way magnetic valve II 7, " mouthful be connected with low-pressure modulating valve 6 suction ports, the air inlet 3 interior air valves 4 that often drive into are connected B on servo cylinder 8 and the compressor 2.A on the two-position three way magnetic valve I 10 " mouthful and two-position three way magnetic valve I I7 between B ' mouth or D ' mouth, the servo cylinder 8 passage be provided with silencing apparatus 9.High pressure modulating valve 5 air outlets connect and are communicated with C ' on the two-position three way magnetic valve I 10 respectively with low-pressure modulating valve 6 air outlets.Mouth is communicated with B ' mouth B on the two-position three way magnetic valve II 7 for A ' mouth and A on the two-position three way magnetic valve I 10 " mouth is communicated with C ' mouth and C ", and " mouthful connection, " mouth is communicated with for D ' mouth and D.
Embodiment 2: with reference to Fig. 1.The working principle of the two pressure output control systems of helical-lobe compressor: during the normal air feed of compressor 2, the control gas of taking from barrel of oil and gas 11 is by two-bit triplet electromagnetic valve I 10 arrival two-bit triplet electromagnetic valve II 7.Low pressure air feed is if desired just connected low-pressure modulating valve 6 by control two-bit triplet electromagnetic valve II 7, and then control often drives air valve 4 into and close fully, satisfies the low pressure air feed.High-pressure air feed is if desired just connected high pressure modulating valve 5 by control two-bit triplet electromagnetic valve II 7, and then control often drives air valve 4 into and open fully, satisfies high-pressure air feed.
What need understand is: though the foregoing description is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any model utility that does not exceed in the utility model connotation is created, and all falls in the protection domain of the present utility model.
