Non negative pressure water supply device secondary water supply system

Description :

　　Non negative pressure water supply device, secondary water supply system, non negative pressure water supply equipmentWorking principle:

　　The non negative pressure water supply equipment consists of an AC frequency converter, a remote pressure gauge, and a regulator as the control mechanism, and a complete constant pressure variable water supply system composed of circuit breakers, contactors, and other actuators. Two water pump workers

　　Working state: Pump 1 is operating with variable frequency, and the frequency rises to a certain set value and reaches the set pressure. At this time, the variable frequency device is working in a constant pressure state. When using water, the pressure drops and the water pump maintains a certain set frequency for a period of time

　　After the interval, if the set pressure cannot be reached, it will automatically switch to the power frequency operation of pump 1 and start the frequency conversion operation of pump 2. When the water consumption decreases, pump 1 stops and pump 2 operates at a variable frequency, increasing the frequency to a certain set value to maintain

　　Maintain the set pressure to function as a constant pressure variable.

　　Non negative pressure water supply equipment is a type of pressurized water supply unit that is directly connected to the municipal water supply network, and is connected in series with the residual pressure of the municipal water supply network to ensure that the pressure of the municipal water supply network is not less than the set protection pressure (can be

　　It is a secondary pressurized water supply equipment with a relative pressure of 0, and when the pressure is less than 0, it is called negative pressure.

　　Non negative pressure water supply equipmentMain functions:

　　1. Fully automatic completion of the entire operation process of soft start, frequency conversion to power frequency operation, and stop for multiple water pump units.

　　2. According to changes in water usage, it becomes the start and stop of multiple pump units.

　　3. The LED display with pressure setting value and actual pressure value is the main function.

　　4. There is LED frequency indication, frequency conversion abnormal indication, and motor fault condition display.

　　5. Main protection functions: It has main functions such as undervoltage protection, overvoltage protection, overload protection, short circuit protection, stall prevention, and burn prevention.
