Abstract
Compressed gases are gathered from a plurality of compressors and employed if required. A pressure of compressed gas thus gathered is measured by a pressure sensor to generate a pressure signal, whichis transmitted to a control. The signal is transmitted from the control to electromagnetic switches to control motors for the compressors to determine which of the compressors run.
Description
Technical field
The present invention relates to a kind of method of controlling a plurality of compressors.
Background technology
Japan Patent No.2875702 has disclosed the method for a plurality of compressors of control in a kind of system, and wherein the Compressed Gas that comes out from a plurality of compressors is collected into a forbay the inside, and desired compression gas can take out from the inside.
When the Compressed Gas from compressor was charged in the forbay, wherein Compressed Gas took out use from this forbay, and high frequent ground starts and stops, if the pressure differential of bound is too small, can cause the inefficacy of compressor and the heavy damage of motor this moment.
Therefore, along with the increase of forbay volume, upper pressure limit remains and is higher than working pressure 0.2MPa, to increase the pressure differential between the bound.
Yet, use this method, need the long period to operate and improve driving power, thereby increased operating cost.The compressor continuous firing has caused the shortening in compressor life-span under high pressure.
And then the rotary speed of compressor is set by upper limit of pressure, is necessary to reduce when operate as normal rotary speed.Operation has just reduced the amount of gas like this, thereby has reduced the efficient of compressor.
Compressor cools off by cooling fan, and cooling fan rotates under low speed and just reduced cooling effect.Like this, just caused the lost of life of end sealing and bearing.
Summary of the invention
In view of shortcoming above-mentioned, the control method that the purpose of this invention is to provide a kind of compressor operation, hang down the number that increases the compressor of work down in limited time to approaching when pressure, and prescribe a time limit on approaching at the pressure height, the number of the compressor of minimizing work, reduce the operating time with reduction operating cost, thus the life-span of improving compressor, end sealing and bearing.
The invention provides a kind of method of controlling a plurality of compressors, comprise following step: collect from the Compressed Gas of a plurality of compressor outputs with similar performance; The pressure of the Compressed Gas of measurement collection and with pressure signal transmission to the work compressor deciding section of controller; Compression pressure between the bound is divided into a plurality of stress levels, and the number of stress level equals the number of above-mentioned compressor; When pressure signal reaches the border of above-mentioned stress level, the number of the compressor of decision work in the work compressor deciding section of controller; Which compressor the signal of the work compressor deciding section by coming self-controller indicates is selected to work in the part at one of controller; And the signal of the selection part by coming self-controller opens or closes switch, to start or stop one of them of described a plurality of compressors.
Description of drawings
Above and other features and advantage of the present invention with reference to the accompanying drawings from following about can be clearer the description of embodiment, among the figure:
Fig. 1 is the view of one embodiment of the invention; With
Fig. 2 is the figure line that has shown the pressure variation of Fig. 1 compressor.
The specific embodiment
Fig. 1 illustrates one embodiment of the invention.
Compressed Gas, for example compressed air is extracted out from a plurality of compressors, is charged in the forbay.The compressed air of requirement is emitted from forbay and is used.Compressed air is not to be charged in the forbay always, but can directly emit from conduit.

8Check-valves 4 stop the compressed air that from compressor, flows out to flow back to.Compressed air all is charged in the forbay 5 by check-valves 4, and compressed air wherein uses for target 7 by opening and closing a valve 6.For the Compressed Gas in the forbay 5 being remained under the pressure of expectation, compressor 1 is controlled on the compressed-air actuated feedback basis in determining forbay 5.
Compressed air pressure in the forbay 5 is measured by pressure sensor 8, to produce pressure signal, pass to controller 9, controller 9 has a deciding section 10 to decide the number of the compressor of work, and has one to select part 11 to start and stop any one compressor.According to the pressure signal that pressure sensor 8 is measured, the number of deciding section 10 definite compressors 1 of being worked.In general, the compressor of work is to decide according to the pressure signal between the predetermined bound.
In the embodiment of first-selection, each in the compressor 1 has close performance, and the pressure between the pressure bound is divided into the stress level of similar number according to the number of compressor 1.When the pressure signal of being measured exceeds the stress level of expectation and reaches its border, change the number of the compressor 1 of work.
Especially, the pressure signal increase of being measured also reaches the stress level that is higher than the horizontal one-level level of desired pressure.Then, from the compressor 1 of being worked, reduce the number of one compressor, be defined as new work compressor number.And pressure signal reduces and reach the stress level that is lower than the horizontal one-level level of desired pressure.Then, from operated compressor 1, increase by one compressor number, be defined as the compressor number of new work.
The number signals of determining from deciding section 10 are passed to selects part 11, selects which compressor start or stops.Such selection is undertaken by the predesigned order that starts and stop.More suitably method is, can give compressor 1 with numerical order and with this sequence starting with stop.By numerical order, any one compressor 1 starts comparably and stops, and has avoided indivedual high frequent to start like this and stops or the shortcoming of work really long days.
When compressor 1 chosen part 11 that starts or stops was selected, a signal was delivered to operation part 12, opens or closes power supply for corresponding motor 2 from being delivered to electromagnetic switch 3 here, and the compressor 1 of selecting part 11 to select like this just starts or stops.
