 Experts explain the application of the principle of water pressure tank: pressure tank is the use of the tank to the compressibility of air conditioning and storage of water and keep the required pressure, so called pressure water supply equipment, which acts as towers and high pool. Because of its water supply pressure is maintained by means of compressed air tank, and therefore, the mounting height of the tank can be unrestricted. Coupled with a large investment in this equipment is less water tower, building fast and easy demolition, flexibility, high degree of automation, it is suitable for adequate water, electricity normal small village water supply. But its a small amount of water to adjust the pressure decay faster, pump start frequent, high operating costs, and require large quantities of water unfit pressure stabilized. Pressure tank is usually installed between the pump and pipe distribution network. After the pump starts, namely water supply pipe network, the excess water to the storage tank, and the tank water level rises, the air is compressed tank vertical water tower, the pressure will be increased. When the tank pressure reaches a predetermined limit pressure water tower, pipe and tank top by communicating the electrical contacts of the index turned limit contact, send a signal to cut off the power supply, stop the pump. Users continue to water, compressed air tank pressure tank into the pipe network, the water level drops, the air pressure inside the tank drops. When the pressure drops to the lower limit of the desired value, the electrical contacts of the index that is turning the lower contact, relay, motor and power supply is turned on, the pump starts working again. Under normal circumstances, the pump can operate in the absence of control, according to changes in water, self-adjusting pump-OFF times and working hours to ensure continuous water supply to the pipe network. Usually in the same way water supply system, set up more than one common pump, several large water pump full of water supply to open one or two hours. When using constant pressure water supply equipment constant pressure water supply, it is used in two ways, one is all pumps equipped with an inverter; Second, each pump is equipped with an inverter. Kaifeng Pacific supply equipment considers the latter method based on pressure feedback signal, automatically adjust the output frequency through the PID operation, change the motor speed, and ultimately achieve the purpose of civilian pipe network constant pressure water tower on a closed loop, is relatively simple, but high cost. The former method is low cost, poor performance than the latter, but more complex control procedures, is the next major development direction. Above the pump operation is controlled frequency counters, frequency of water supply system which is the most important, the most critical part. Variable-speed pump control cabinet system through the pipeline pressure sensed by the inverter system built-in PID controller operation, adjust the output frequency, and then realize constant pressure water supply pipe network. Overrun signal frequency converter (generally as a pipe network pressure limit signal) can be timely notified PLC pump switching frequency. In order to prevent water hammer phenomenon, the pump will switch its outlet valve linkage. Frequency control cabinet works as follows: Frequency of water supply energy-saving control cabinet assumed that the entire system is composed of four pumps, a converter, a PLC and a PID and a pressure transmitter and a number of auxiliary member. Function of each part as follows: water pipes installed in the pressure pipe network pressure transmitter will be converted into electrical signals 1-5 volts; inverter is used to adjust the pump speed to regulate the flow; PLC for logic switching. In addition, the above system is also equipped with external auxiliary circuits to protect the automatic control system fails to maintain system operation through manual adjustment methods to ensure continuous production.
