37KW PM VSD Harga Murah 50 Kompresor Udara Tipe Sekrup Putar HP

Take this 37KW power frequency screw air compressor as an example. The average air production only accounts for 70% of the rated airflow. The machine runs 8000 hours a year. The electricity fee is 0.7CNY/kWh. Compared with the VSD air compressor, it will consume more electricity bills.

1) No-load power consumption: 30% unloading time * no-load current consumption (45%*37KW/hour)8000 hours/year*0.7CNY/kWh=28000CNY/year

2) Differential pressure power consumption: 70% loading time * differential pressure loss (14% * 37KW/hour) * 8000 jam/tahun * 0.7CNY/kwh = 20300CNY/year.

Untuk menyimpulkan, the PM VSD 50 hp rotary screw compressor can save energy consumption of 28000+20300=48300 yuan/year. This can buy a new machine. It’s higher than the 50 hp compressor price.

The compressor airend adopts a five-six-tooth ratio rotor. Compared with the ratio of four and six teeth, it reduces drop by 25%. Karena itu, greatly improves the compression efficiency. The large rotor results in a small leakage area. Further, it improves compression efficiency. Di samping itu, we use German processing equipment. Tooth shape precision is high. Under continuous operation, the rotor can maintain the optimum clearance value. So airend is stable and efficient. Lebih-lebih lagi, the bearing is the Swedish SKF brand. Dengan demikian, the airend is more durable.

Pertama, the PM compressor motor remains efficient at low loads. At full load, it is at least 9% more efficient than asynchronous motors. Di samping itu, as the speed is reduced, the energy efficiency remains the same.

Kedua, it has a large starting torque. The ratio of the maximum dynamic torque to the rated torque can be more than 3 waktu. The general asynchronous motor is only 1.6 waktu.

Ketiga, the control is more stable. The response time of the permanent magnet motor is less than 50ms. Air production can be adjustable in a wide range in an instant.

keempat, high-temperature-resistant rare earth RuFeB magnets are used. Karena itu, the stability of the 50 hp screw compressor is better.

The air compressor air filter adopts multi-stage sealing. It’s flexible and stable. And oil filter can withstand high temperatures of 120°C. The classification efficiency can reach 99%. Compressed air oil content ≤ 3 ppm. The intake valve has a high vacuum. Selain itu, the cooling fan has low noise and high air volume.
