Product Name: Shanghai Dragons Automatic frequency of water supply facilities in the area 

 Product Description: Our company uses advanced hydraulic model. Shanghai Dragons in our area of water supply equipment is compact automatic frequency beautiful, energy efficient and stable performance characteristics. It is the water tower, high water tank, pressure tank water supply device ideal replacements. Have to save energy, save investment, no maintenance, reliable operation, is leading the future of water supply equipment products. I developed a frequency counter can also be used in the motor industry needs to adjust the device, adjust the precision and energy have obvious effects. Features: 
 1, water quality is high: the export of the equipment used constant pressure pump control system of water no matter what changes are to make pipe outlet pressure remains constant. 
 2, reliable: the frequency converter equipment imported and domestic high-quality pumps, with perfect protection and automatic, manual conversion, the operation is very reliable. 
 3 Energy efficient: The device can change according to the user to adjust the water pump speed, so that the pump is always working in the high area, power saving effect is obvious, than the constant speed pumps can save 35%. 
 4, the operation is simple: The use of automatic control equipment, operators only need to convert cabinet switch, users can achieve the required conditions. 
 5, small footprint, easy installation: just a set of complete equipment control cabinet and one pump unit, installation is very convenient. 
 6, to extend the service life of pumps and motors: for more than one pump can achieve reliable soft-start, and take turns running, greatly extending the service life of pumps and motors. 
 7, Applications: for traffic from 5 to 5,000 tons / hour, lift 20 to 140 meters. 
 8, significant economic benefits: the use of the equipment, not to set the roof water tank, reducing the cost of the building, but also to overcome the fluctuation of air pressure tank, pump start frequency and the construction of towers one large investment and long construction period, the cost of higher shortcomings. 
 Main function 
 1, the automatic completion of more than one water pump soft start, variable frequency operation and to stop all operations process. 
 2, according to the change water into more than one pump start and stop. 
 3, the pressure setpoint and the actual pressure value of the LED display. 
 4, a LED indicating the frequency, frequency exception indicates, the electrical fault condition appears. 
 5, protection: protection has undervoltage, overvoltage, overload, short circuit protection, stall prevention, burn prevention and other functions.
