Introduce the basic situation of the product
The single pump frequency conversion system adjusts the speed of the water pump motor by changing the power frequency through the frequency converter, thereby achieving precise control of water flow and pressure. When the pipe network pressure drops, the system will automatically start the water pump to supply water, ensuring the stable operation of the water supply system.
Usage Environment
1. Temperature and humidity: Single pump frequency conversion equipment is suitable for working in an environment of -10℃ to 40℃, the relative humidity should be less than 95% (at 20℃), and there should be no condensation
2. Power quality: The power supply voltage should be within the range of -15% to +10% of the rated voltage, the phase imbalance rate should be less than 3%, and the frequency is 50Hz±2Hz
3. Installation environment: The equipment should be installed in an environment without corrosive gases, flammable and explosive gases and liquids, and avoid direct sunlight and strong electromagnetic interference 4. Ventilation and protection: The inverter should be installed vertically upward, and leave enough installation space. The upper and lower net space should be greater than 100mm, and the left and right net space should be greater than 50mm . The device should be equipped with a cooling fan for forced cooling to ensure good heat dissipation effect.

Product Usage
Suburban villa water supply, farms, rural areas, and schools digging wells to draw water: These scenarios usually require pressurized water supply, but do not require water towers. Using a single pump variable frequency constant pressure device can reduce costs, provide stable water pressure, and is easy to operate and has a long life
Floor pressurization and equipment matching: In high-rise buildings or places where pressurization is required, single-pump variable frequency constant pressure equipment can provide stable water pressure to meet the water needs of different floors.
Water pipe pressure boosting: In the water pipe pressure boosting technology, the single pump variable frequency constant pressure equipment can adjust the water pressure according to actual needs to ensure the stable operation of the water supply system.
Product Operation Guide
How to use and operate the machine
1. Manual adjustment To manually adjust a single-phase variable frequency water pump, you need to master the following steps: (1) Turn on the power supply and motor to enter the manual speed adjustment state; (2) Enter the speed adjustment mode and adjust the frequency change until the required water flow and water pressure are reached; (3) Adjust the speed and current to keep the water pressure and water flow stable. 2. Automatic control In addition to manual adjustment, we can also use automatic control to adjust single-phase variable frequency water pumps. Automatic control requires the following steps: (1) Install sensors to detect water flow and water pressure; (2) Use a PLC or DCS control system to automatically adjust the frequency change and speed; (3) Set appropriate control parameters to achieve the required water flow and water pressure.
Frequently asked questions
1. Unstable voltage
Check the power supply voltage, connect a voltage regulator if necessary, and set it to the required voltage.
2. Overload
Reduce the operating load of the water pump, check the gap between the motor rotor and stator, and perform dynamic balancing correction if necessary.
3. Mechanical obstacles
Check whether the water pump is blocked, use appropriate tools to clean the water path and eliminate mechanical obstructions.
4. Loud water noise and unstable water pressure
Check whether the air is turbid and the exhaust is smooth, and replace or repair hardware facilities if necessary.
