Nanjing secondary water supply equipment manufacturers (Dai: 13548670698) pressurized pipe network overlying water supply equipment, water piping pressure equipment, Hanson water, inadequate water pressure professional solution. Vacuum pipe network steady flow of pressurized water supply equipment, production and processing, professional non-vacuum pipe network layers, layers of water supply pipe network equipment manufacturers, Deputy welcome to join. (National Recruitment Agency: 13548670698) All devices are tailored according to customer specifications, prices vary depending on the configuration, please call Miss Dai: 135-4867-0698. Nanjing secondary water supply system control principle: 1. entire section can be configured to pump cycle soft start work or be free to set the main pump and ancillary small pump 2. Design with RS485 interface for easy connection to PC or touch screen, conduct configuration control; 3. The new power supply design, anti-interference ability to AC grid has better adaptability; 4. parameters in more detail, the equipment control process is more refined, more energy-efficient equipment to work; small 5. Variables Lower frequency pump can be set independently, better play small pump efficiency and energy savings; 6. alternative mode of operation is shut down, better to prevent water hammer effect; 7. complete sleep function during dormancy according to pressure drop extent timely fill pressure; 8. backlit LCD display, all parameters in the culture, friendly interface. Using the keyboard display panel and the host sub-structure, easy to install, host DIN35 rail mounting; 9. Digital mode control: secondary water supply system pressure using digital mode control, smart regulation, equipment, fast response, high accuracy, good stability, PID parameter testing; 10 soft-start cycle: Secondary water system uses self-compensation technology, equipment, machinery and electrical shock is small, while the pressure switch when small fluctuations; 11. timer switch control: real-time clock (monthly error does not exceed 1 point) , data can be retentive, set up to sixth day time switch timing control; 12. Regularly changing pump features: multi-pump equipment so that the average working time for each pump the same; 15. Flow compensation function: Secondary water variable transformer control system implementation, internal compensation and compensation optional external flow meter, the amount of compensation is adjustable; 13. dosing pumps, secondary water system variable pump automatic inspection function; 14 with manual debugging features. Nanjing secondary water supply equipment features automatic completion of several major water pump soft start. Conversion to full operation of the process and stop frequency operation. - According to changes in water. Into a multi-pump start and stop. Pressure setpoint and the actual pressure value LED shows the main features. There are LED frequency indication. Frequency exception indicates, the motor failure conditions. The main function of protection. Undervoltage protection, overvoltage protection, overload protection, short circuit protection, stall prevention, burning to prevent major functions. Hanson Water Equipment Co., Ltd., Changsha, Nanjing no negative secondary water supply equipment, including frequency of water supply equipment, constant frequency of water supply equipment, pipe network layers (non-negative) frequency of water supply equipment, intelligent frequency of water supply equipment. Suitable for living water supply, water use in public places, such as widely used manufacturing supply. Is to solve due to insufficient pressure or flow can not reach the height of water users, and specially developed design of the new eco-friendly professional equipment. Supply equipment can be divided into the following types, frequency negative pressure water equipment, water tower equipment, constant pressure water supply equipment, widely used in the market have constant pressure water supply equipment, fire water supply equipment, no negative pressure water equipment.
