Pump power control cabinet

Pump power 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 features, a new concept of self-developed series of 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. Product Overview??? With the rapid development of China's modernization drive, the power supply has been improved, although to a large extent, but the waste of energy is still quite amazing. According to relevant statistics, China's fans, pumps, installed capacity of more than 100 million kilowatts, accounting for about 30-40% of the national consumption of total electricity consumption. Due to the nature fan, water pump working mechanism, working motor running at constant speed state, and often work requirements of wind, water flow requirements in the running variable condition, and many units during the system design, the design capacity is too large, the system does not match reasonable, often "big horse car", resulting in fans, pumps operating efficiency is only 30-50%, which is not only the high operating costs and a waste of valuable energy. Therefore, to do energy conservation fan, water pump, and has important significance for the development of the national economy. ? Dr. Paul fan / pump power control cabinet combined fan and pump working characteristics, adjust the fan according to production process requirements, the pump motor input frequency, change the motor speed, according to the production process requires reasonable regulation of gas and liquid flow, velocity and pressure, replacing windshield behind the regulation of the fan or pump valve opening degree way to achieve both optimization of the production process, but also the dual purpose of saving 20% ??-50% electricity?. 2 Features ● Excellent soft-start and soft-stop function, reduce motor starting current, reduce the impact of the current impact of the grid to protect the motor, anti - water hammer pump stop; ● optimize the production process, so that gas and liquid flow, flow rate, pressure is more reasonable; the system uses closed-loop control parameters overshoot fluctuation - a small range, acceleration and deceleration can be automatically adjusted according to process requirements; ● very sensitive fault detection, diagnosis, digital display, improve the reliability of operation of the motor; ● section ● good; the user can choose with or without a "work / frequency switching", convenient; ● After having remote automatic control RS-485 interface for remote control; ● Short circuit, overload, overheating and other sound protection electric effect, according to the site to process requirements are inconsistent, energy-saving rate of 20% -50% 3, the scope of application of the product is widely used in industry, heating boilers, cement kilns, coal, metallurgical industry blast furnaces, converters, chemical plants, pharmaceutical plants , sewage treatment plants, oil fields, petrochemical plants, water supply companies and other industries, enterprises and occasions centrifugal fans, axial fans, Luoci fans, air compressors, centrifugal pumps, submersible pumps, circulating pumps, submersible pumps, transmission Frequency and flow pumps, high pressure injection pumps and other equipment, the flow rate and pressure regulation control.
