Nowadays, the development of frequency converter has been quite mature, more and more industries have the use of frequency converter, the emergence of special frequency converter for water pump, so that the hydropower industry has been higher development. So what are the functions and characteristics of the special inverter for the pump?

Pump special inverter is a kind of power converter which uses non-inductive vector technology to control output voltage and frequency to change the running speed of AC asynchronous motor. The current sensor accurately detects the change of three-phase output AC signal and phase Angle, and automatically corrects the frequency by non-inductive vector calculation to achieve the effect of fixed motor speed when the load changes.

Pump special inverter features are as follows:

1, the built-in parameter automatic tuning function can automatically detect the motor characteristics and automatically set its related parameters, to ensure that the inverter can continue to optimize the motor operating characteristics and obtain the maximum torque output when the motor operating parameters change over time.

2, the whole field of protection function: low voltage, overvoltage, overcurrent, prevent motor stall, overload, overheating and other protection.

3, standard V/F mode, non-inductive vector mode, output power (torque) control mode.

4, specially designed for industrial machinery control functions: Six multi-function programmable digital input function, three multi-function programmable digital output multiple functions, timer/counter, speed tracking function, flipflop function, automatic operation function, built-in standard RS485 communication interface, can allow a single or multiple frequency converter to be dynamically controlled by the main computer at the same time. And can control multiple inverters at the same time, built-in rich PID function.

5, built-in PID regulator, in the realization of constant pressure and constant temperature control, it can be very convenient to achieve closed-loop system control of temperature, pressure, flow and other process quantities.

In addition, the following should be noted:

1, submersible pump and other large load occasions recommend the use of a large power inverter;

2. When the distance between the motor and the inverter is far, please install a reactor at the input and output ends of the inverter to avoid high-order harmonic interference to accelerate the frequency converter and motor aging;

3. Switch devices are prohibited between the frequency converter and the circuit breaker, especially the leakage protector.
