Abstract
The utility model discloses a control device for an electric-screw integrated air compressor. The control device comprises a control-panel control terminal, a first power supply module, a signal transmission control terminal, a second power supply module, an RS-232 (Recommended Standard 232) communication module, an RS-485 (Recommended Standard 485) communication module, an air compressor execution module and a port signal display panel. The control device has start-stop and operation control functions on a motor and protection functions on short circuit, stalling and the like, temperatures of multiple points can be subjected to detection and control protection, the load rate can be automatically adjusted, and the pressure balance is controlled; the communication modules have multi-station capability, so that multi-point interconnection is very convenient, and a lot of signal lines can be saved; the control device has common-mode interference suppression capability, the noise resistance is good, LEDs (Light Emitting Diodes) have Chinese and English display functions, and the overall integration level, reliability and cost performance of the device are relatively high.
Description
Technical field
The utility model relates to a kind of air compressor control device, particularly for electric screw Integral air compressor control device.
Background technique
Electric compressor power of motor is generally larger, starts unloaded star one triangular patterns that adopt more, and loading and unloading manner are all instantaneous.This makes air compressor when starting, have larger inrush current, when loading and unloading, to plant machinery, impacts larger; Both can cause mains voltage fluctuation, and also can make compressed gas source produce larger fluctuation, wearing and tearing that simultaneously also can acceleration equipment, the service life of reducing equipment.Because the dragging motor of general electric air compressor itself can not speed governing, therefore just directly the change of working pressure or flow realizes the coupling of reduction of speed regulation output power, motor does not allow frequent starting, cause motor when gas consumption is few still to want no-load running, often need Frequency Conversion Modification.The water that the personal factor that seasonal factor, factory that Yin Dongxia substitutes are on and off duty and the technical factor of water treatment etc. cause and air heat recovery rate is low and energy consumption large etc. be another outstanding problem of air compressor.
Based on cost reason, within a very long time, air compressor adopts Single-chip Controlling and nixie tube display working condition by control gear.Although the manufacture cost of this method is very low, be difficult to process self being easily disturbed, revising, and the defect such as Function Extension inconvenience.The discontinuous disequilibrium of methane gas that fluctuation during plant produced causes is also very large, if adopt the planning air-supply spare system of peak value coupling, will have in the face of high-power motor is with adaption demand.In addition, the noise of communication system operation and information flowrate problem are also the key factors of restriction electric compressor work.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of electric screw Integral air compressor control device is provided.
A kind of electric screw Integral air compressor control device comprises control panel control terminal, the first power module, signal transmission control terminal, second source module, RS-232 communication module, RS-485 communication module, air compressor Executive Module, port signal display floater; Control panel control terminal, RS-232 communication module, RS-485 communication module, signal transmission control terminal connect in turn, the first power module is connected with control panel control terminal, second source module is connected with signal transmission control terminal, and air compressor Executive Module is connected with signal transmission control terminal respectively with port signal display floater.
On described control panel control terminal, be provided with switch key, control button, malfunction alarm display lamp, liquid crystal display panel.
The utility model has the omnibearing protection functions such as start-stop, operation control function and short circuit, stall, phase shortage, overload, imbalance to motor; can carry out anti-reverse protection to air compressor; multi-point temp is detected and system protection; can automatically regulate Rate of load condensate; pilot pressure balance; communication module of the present utility model has multistation ability; very convenient for multi-point interconnection; can save many signaling lines; and there is the ability that suppresses common mode disturbances; noise immunity is good, and LED has Chinese and English Presentation Function, installs whole level of integration, reliability, cost performance higher.
