What Are The Energy-Saving Measures For Anti-Corrosion Magnet
TIME：2024-07-11 Author：admin Views：
Anti-corrosion magnetic pumps include anti-corrosion fluorine-lined pumps and anti-corrosion stainless steel pumps. Industrial anti-corrosion pumps are usually driven by motors. So how can operators save energy when using motors? This is what many operators want to do. The following introduces the measures and methods for energy saving of anti-corrosion magnetic pump motors.
1. Choose the energy-saving motors. Compared with ordinary motors, high-efficiency motors optimize the overall design, use high-quality copper windings and silicon steel sheets, reduce various losses, reduce losses by 20%~30%, and increase efficiency by 2%~7%. The payback period is generally 1~2 years, and some are several months.
2 .Frequency conversion speed regulation. Most fan magnetic pump loads are selected according to the full-load working requirements. In actual applications, most of the time is not in full-load working state. Since AC motor speed regulation is very difficult, wind shields, return valves or start-stop times are often used to adjust the air volume or flow. At the same time, it is difficult for large motors to start and stop frequently under the power frequency state, and the power shock is large, which is bound to cause power loss and current shock during start-stop. Using a frequency converter to directly control fan and pump loads is the most scientific control method. When the motor runs at 80% of the rated speed, the energy saving efficiency is close to 40%. At the same time, closed-loop constant pressure control can also be achieved, and the energy saving efficiency will be further improved. Since the frequency converter can achieve soft stop and soft start of large motors, it avoids voltage shock during startup, reduces motor failure rate, and extends service life. It also reduces the capacity requirements and reactive power loss of the power grid.
3. Liquid speed regulation of wound-rotor motors
Liquid resistance speed regulation technology is developed on the basis of the traditional product liquid resistance starter. The purpose of step-less speed regulation is still achieved by changing the distance between the pole plates to adjust the size of the resistance. This makes it have good starting performance at the same time. It is powered on for a long time, which brings about the problem of heating and temperature rise. Because the anti-corrosion pump motor adopts a unique structure and a reasonable heat exchange system, its working temperature is limited to a reasonable temperature. The liquid resistance speed regulation technology for wound-rotor motors has been rapidly promoted due to its advantages such as reliable operation, convenient installation, large energy saving, easy maintenance and low investment. For some wound-rotor motors that do not require high speed regulation accuracy, wide speed regulation range, and do not frequently regulate speed, such as large and medium-sized wound-rotor asynchronous motors in equipment such as fans and water pumps, the liquid speed regulation effect is remarkable.
