Compressor saving control cabinet Dr. Paul Smart Saver, is the introduction of cutting-edge German mature intelligent power control technology, combined with the world's most high-frequency technology features, and domestic application characteristics, the independent development of a new concept Series high performance. Under the premise of improving the stability increases simple PLC, PID practical section, flexible input and output terminals, online parameters setting, self-identification signal transmission failures, power outages and downtime parameter storage, electrical energy control, traverse control, RS485 control, Fieldbus control and a series of practical operation of advanced control functions. Equipment manufacturers and end customers to provide highly integrated integrated solutions to reduce system acquisition and operating costs, improve system reliability is of great help. 1. Overview of the compressor as the power output device is widely applied in all walks of life, power from a few kilowatts to hundreds of kilowatts range, power consumption in a large proportion of the entire production process. Compressor working process is as follows: after completion of the compressor motor is started, the cylinder intake valve opens, starting compressed air, when the cylinder is connected with the tank pressure P reaches the set value of P1, the intake valve and the valve is closed, the motor is unloaded; as production increased power consumption of gas consumption, air compressor cylinder pressure P dropped down slowly lowered to the lower limit value P2, the air compressor intake valve is opened, the motor turn the load state, and then the pressure P starts to rise. So it goes, the air compressor motor has been in a "load" and "unload" alternate operation, when the motor is unloaded, compressor motor is completely doing useful work, energy is wasted. The barometric pressure varies between P has been on the limit and lower limit P1 P2, in fact the production requirements of the pressure P is not less than the lower limit value P2 as long as you can, and the pressure increased from P2 to P1 of "climbing pressure "The consumption of electricity is huge, which is part of the power consumed entirely superfluous is wasted. 2, works when pressure compressor cylinder pressure P reaches the upper limit set value P1, the air compressor energy-saving products - air compressor frequency integrated cabinet by the pressure sensor to transmit this information to the control cabinet central processor, a central processor for immediate pressure P and P1 and P2 values, and computing and data processing, to control the inverter cabinet issued a directive regulating compressor drive motor speed according to instructions, the motor speed and production of Compressed air pressure required to achieve the best fit. This will not only make the air compressor gas pressure control in a relatively stable range, to optimize the production of power supply, but also to the air compressor power consumption is greatly reduced. 3, Features l excellent soft-start function reduces inrush of air compressor and electrical components on the grid, prolongs motor life;? L make constant supply pressure control in the best position to optimize the gas quality? ;? l Digital control, easy to operate;? l RS-485 communication interface and standard communication protocols, equipment upgrades and fortune easy to control; l-saving / easy to bypass dual-loop manual and automatic conversion, automatic fault bypass, safe? reliable;? l can achieve a saving control cabinet control multiple air compressor, air pressure according to the instantaneous value P and pressure limits P1 and P2 lower limit control, automatic intelligent choice for each start and stop air compressors ;? l saving effect is remarkable, the general energy-saving rate of 10% -30%.
