Abstract

The invention discloses a power-saving device based on cooperation of N parallel compressors and relates to a power-saving device based on cooperation of compressors. In orders to resolve the problem of a large power consumption produced by more emptying when a plurality of existing air compressors simultaneously work, the power-saving device based on cooperation of the N parallel compressors comprises N compressors, wherein N is an integer more than 2. The power-saving device further comprises a controller and a flow sensor, wherein the compressed air output ends of the N compressors are respectively communicated with the compressed air input ends of N valves; the compressed air output ends of the N valves are communicated and act as the compressed air common outlets of the N compressors; the flow sensor is arranged at the compressed air common outlet of the N compressors; the flow signal output end of the flow sensor is connected with the flow signal input end of the flow sensor; and the N output ends of the starting control signals of the controller are respectively and correspondingly communicated with the input ends of the starting control signals of the N compressors. The power-saving device disclosed by the invention is suitable for the power-saving device based on cooperation of compressors.

Description

The collaborative battery saving arrangement of N platform parallel connection compressor

Technical field

The present invention relates to the collaborative battery saving arrangement of compressor.

Background technique

In the metallurgical production process,, require air compressor co-operation more than two to satisfy to compressed-air actuated needs because an air compressor can't satisfy the production needs.

Because during existing many air compressor co-operation, have more emptying and the big problem of power consumption that produces, directly influenced the task that enterprise cuts down the consumption of energy and accomplished.

Summary of the invention

The objective of the invention is when solving existing many air compressor co-operation, have more emptying and the big problem of power consumption that produces, provide a kind of N platform parallel connection compressor collaborative battery saving arrangement.

The collaborative battery saving arrangement of N platform parallel connection compressor, it comprises the N compressor, N is the integer greater than 2; It also comprises controller and flow transducer; The compressed-air actuated output terminal of said N compressor is communicated with the compressed-air actuated input end of N valve respectively; The compressed-air actuated output terminal of N valve is communicated with; And as the pressurized air conjoint outlet of N compressor; Flow transducer is arranged on the pressurized air conjoint outlet place of said N compressor, and the output terminal of the flux signal of flow transducer is connected the input end of the flux signal of controller, and the output terminal of the N of controller start-up control signal correspondence respectively is communicated with the input end of the start-up control signal of N compressor.

The present invention detects the compressed-air actuated demand of user through controller, and controller is controlled the quantity of opening parallelly connected compressor simultaneously according to user's needs, effectively reduces the emptying amount of parallelly connected compressor, reaches to have overcome the big problem of power consumption.

The present invention's ability saving power is more than 50%.

Description of drawings

Fig. 1 is a structural representation of the present invention, and three arrows are represented the flow direction of three compressors from the drain emptying gas among the figure.

Embodiment

Embodiment one: combine Fig. 1 that this mode of execution is described, the collaborative battery saving arrangement of this mode of execution said N platform parallel connection compressor, it comprises N compressor 1, N is the integer greater than 2; It also comprises controller 2 and flow transducer 3; The compressed-air actuated output terminal of said N compressor 1 is communicated with the compressed-air actuated input end of N valve respectively; The compressed-air actuated output terminal of N valve is communicated with; And as the pressurized air conjoint outlet of N compressor 1; Flow transducer 3 is arranged on the pressurized air conjoint outlet place of said N compressor 1, and the output terminal of the flux signal of flow transducer 3 is connected the input end of the flux signal of controller 2, and the output terminal of the N of controller 2 start-up control signal correspondence respectively is communicated with the input end of the start-up control signal of N compressor 1.

The present invention detects the compressed-air actuated demand of user through controller, and controller calculates the quantity that acquisition need be opened parallelly connected compressor simultaneously as required, effectively reduces the emptying amount of parallelly connected compressor, reaches to have overcome the big problem of power consumption.

The present invention's ability saving power is more than 50%.

Be through the increment guard interval after calculating between the surge area of centrifugal compressor,, current limitation reduced through multi-metering and precisely calculating.Through the control of controller 2, open a compressor, the operating current of said compressor is reduced to minimum current; As do not satisfy the user to compressed-air actuated needs, and open second compressor, the operating current of second compressor is reduced to minimum current; And the like to the N compressor; Realize reduction emptying, reduced the purpose of power consumption.

Embodiment two: this mode of execution is that said controller 2 adopts chip microcontroller to the further qualification of the collaborative battery saving arrangement of embodiment one said N platform parallel connection compressor.
