0.75KW-2.2KW water pump frequency conversion constant pressure submersible pump.
The frequency of the frequency converter will automatically change with the change of water pressure to maintain a constant pressure.
Button is still Chinese characters
Advantages of constant pressure water supply inverter
Simple setting, no need to modify parameters;
The two digits on the left of the LED are the set pressure, and the two digits on the right are the real-time pressure of the pressure gauge.
Press the up and down keys to modify the set pressure, and the inverter will keep running at the real-time pressure near the set value;
Built-in PID control and advanced energy-saving software, designed for water pump constant pressure energy-saving control,
Energy saving effect 20%-60% (depending on the actual situation)
It has full water sleep, water shortage sleep and wake-up functions, prolongs the life of the equipment, stabilizes the power grid,
Reduce wear, reduce failure rate, realize soft start and braking functions
XSY-HY adopts a unique control method to realize high torque, high precision and wide range speed regulation drive.
It meets the trend of high-performance optimization of general-purpose inverters, and has the advantage of tripping performance surpassing similar products.
Strong ability to adapt to harsh power grid temperature, humidity and dust interference, greatly improving the stability of the product;
Tighten and directly connect to the port, which can be connected to 0-10v, 0-5v, 4-20ma pressure sensor or remote pressure gauge 2-way multi-function input,
Two outputs (relay optional),
Quick start-stop response, large low-speed torque, under-voltage, over-voltage, over-current, over-heat, short-circuit protection
Optimize the overall design of PWM control technology and electromagnetic compatibility to meet the low noise and low EMI environment requirements of users on site
application:
1. Single-phase fan motor, water pump, axial flow fan
2. Single-phase capacitor start AC asynchronous motor
Features:
Programming key: select normal mode or programming mode (when the inverter is running or stopped, pressing this key is valid;
When modifying parameters, you must press this key to enter programming mode;
Move/Jog key: programming mode switching function, normal mode: Jog Drive motorstate
Data/Save key: function data and function setting key
In normal mode, press this key to display inverter status parameter information,
Such as target frequency and current, temperature;
Programming mode: press this key to display the parameter content,
Press this key again to save the modified parameter value
Up and down keys: parameter number or parameter value increase
Short press the key, the changed digital step changes, indicating jog change;
If you press this key for a long time, the modified value will change rapidly
question and answer :
Dear, the inverter parameters cannot be set when there is no water; Dear, the inverter parameters cannot be set when there is no water;
It will stop and start again in three seconds; how can it be guaranteed that it will not start again in the absence of water?
Water pump inverter HY2 0.75KW
Answer: It will automatically stop about 50 seconds after starting without water, and restart after 10 minutes;
When the water pressure on the right side of the inverter panel always displays 0.0;
We don't think he's pumping water and the motor is short of water. If the motor is short of water,
After 1 minute, the water pressure has not come up, and the display is still 0.0.
We will stop, after ten minutes we will try to start again, start time is 1 minute, water pressure does not rise,
The water pressure is always zero, we stop for another ten minutes,
Until the water pressure comes up after pumping water for 1 minute, the frequency converter and motor run normally at this time.
Repeat cycle.
The 2 parameter settings are P111,P117
