Fan and pump power control cabinet

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 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 always in a constant speed motor running state, and often work in the wind, water flow requirements change in the running condition, many units in the system design, the design capacity is too large, the system match unreasonable, 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 replace the windshield behind the regulation of the fan or pump valve opening degree way, to both optimize the production process, but also the dual purpose of saving 20% ??-50% electricity. ? 2, the product 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, pump to prevent water hammer effect;? Optimize the production process, so that gas and liquid flow velocity, Pressure is more reasonable; the system uses closed-loop control parameters overshoot small fluctuation range, acceleration and deceleration can be automatically adjusted according to the technical requirements;? very sensitive fault detection, diagnosis, digital display, improve the reliability of operation of the motor;? User selectable with or without "Power / Mains switch", easy to operate;? having remote automatic control RS-485 interface for remote control;? has a short circuit, overload, overheating and other sound protection;? good saving effect, according to the site to process requirements are inconsistent, energy-saving rate of 20% -50%. 3. Application 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 frequency control occasions centrifugal fans, axial fans, Luoci fans, air compressors, centrifugal pumps, submersible pumps, circulating pumps, pump, high-pressure injection pumps and other equipment and flow, flow rate and pressure adjustment control.
