Higher utilization and lower operating costs! The AS180 inverter sets a new benchmark for deep-well submersible pump applications
Xinshida has been working in the pump industry for 15 years, AS180 is the earliest series of classic series inverter products launched by Xinshida for the pump industry, with excellent control performance and unique pump application macro has won the trust of many pump partners, especially in the application of deep well submersible pumps has set an industry benchmark and won high praise from customers.
Recently, a waterworks plant in Shanxi province selected 13 sets of AS180 series 90kW frequency converters in Xinshida to transform the deep well pump water intake drive project, replacing the original soft start system with a frequency conversion drive. The original system deep well pump rated power of 75kW, rated head of 320m, flow rate of 50m³/h, the pump is 200m underground, the ground is a super large reservoir, after treatment for the city residents to provide purified tap water.
The original system has low energy efficiency utilization
High operating costs
According to the reservoir level, the number of starts to manually judge and operate the pump is high;
The use of soft starter for multiple times frequent start and stop, the mechanical impact on the pump and motor affects the service life of the deep well pump system, the pump maintenance cycle is short and the workload is large;
The water consumption demand at night in winter is small, in order to avoid freezing the water pipe, the pump frequency operation exceeds the liquid level overflow, resulting in waste of water resources;
After soft start, the water pump runs at a high frequency, with large energy consumption and low energy utilization.
Frequency converters make energy use more efficient
Lower operating costs
The pipeline network is equipped with a pressure transmitter with the liquid level acquisition to compare logic, and the frequency converter PID control realizes automatic speed regulation operation, reduces manual intervention, and makes the system run more efficiently;
Frequency conversion start is smoother, reducing the impact on pumps, motors and pipe networks, lengthening pump maintenance cycles, and reducing maintenance costs;
Frequency conversion control ensures the stability of water supply flow and pressure, and avoids water waste caused by frozen pipe cracking and high-level water overflow in winter;
The frequency converter adjusts the pump flow by adjusting the speed, and the precise control is more energy-saving.
Xinshida deep well pump is suitable for the technical characteristics of frequency converters
It can provide high protection IP55, drive control integration, backpack installation and other customized models;
Compatible program upgrade to drive a variety of permanent magnet synchronous motors;
Integrated pump control logic module, constant pressure control, constant flow control, constant frequency control logic easy drive control;
A variety of parameter application macros, according to the control device application requirements directly called;
Unique GVC control mode, improve control performance, improve output torque, drive the pump more easily;
Built-in high-efficiency motor protection logic, short circuit protection, motor overload, blocked rotation protection, water shortage protection, overpressure protection, etc., to es**rt the stable operation of the pump.
