Water pump inverter, also known as pump frequency conversion controller, Renda pump special type pump inverter adopts core patented technology, by the domestic leading inverter manufacturer Shenzhen Renda Group research and development, design and manufacturing.
When the automatic control system of water supply is working, the equipment detects the pressure change of the water supply pipe network in the water supply pipe network when the water consumption changes, and continuously transmits the changed signal to the inverter, after the microcomputer judgment calculation and comparison with the set pressure, the controller issues a command to change the frequency, the controller changes the speed of the pump motor and the number of units enabled by changing the frequency, automatically adjusts the peak and valley water consumption, and ensures that the pressure of the water supply pipe network is constant to meet the needs of users.
Renda pump inverter is suitable for saving energy for various types of pumps, such as: horizontal water pump, vertical water pump, inclined water pump and so on.
The characteristics of Renda pump inverter are:
1. Power saving: optimized energy-saving control software enables the pump to achieve maximum energy-saving operation;
2. Water saving: set the pressure of the pipe network according to the actual water use, automatically control the water output of the pump, and reduce the phenomenon of water running and leakage;
3. Reliable operation: the soft start of the pump is realized by the frequency converter, so that the pump can realize the shock-free switching from power frequency to frequency conversion, prevent the impact of the pipe network, avoid the pressure of the pipe network exceeding the limit, and the pipeline breakage.
4. Network function: the frequency conversion pump adopts the full-Chinese industrial control configuration software to monitor each station in real time, such as the voltage, current, working frequency, pipe network pressure and flow of the motor. And it can accumulate the electricity consumption of each station, accumulate the water output of each pump, and provide various forms of printed reports for analysis and statistics.
5. Flexible control: segmented water supply, regular water supply, manual selection of working mode.
6. Perfect self-protection function: if a pump fails, take the initiative to send an alarm message to the host computer, and start the backup pump at the same time to maintain the balance of water supply. In the unlikely event of a malfunction of the automated control system, the user can operate the manual system directly to protect the water supply.
