Silent Screw Compressor

1.The silent screw compressor has constant output pressure, eliminating the extra 2 bar pressure burden, and saves 14% energy compared to industrial frequency air compressors.

2.At low speeds, the efficiency of ordinary motors is very low, while permanent magnet synchronous motors also maintain high efficiency at low speeds.

3.The silent screw compressor uses UH grade neodymium iron boron material, with a temperature resistance of up to 180°C, which is much higher than the normal operating temperature of the motor, and the magnetism will not decrease for a long time.

4.The two-stage compression permanent magnet variable frequency air compressor motor has high efficiency, 93% ~ 96%; compared with ordinary motor efficiency: 87% ~ 92%.

5.The two-stage compression permanent magnet variable frequency air compressor adopts an integrated design of the host motor. The motor rotor with permanent magnets is directly installed on the extended shaft of the host rotor. The transmission efficiency is 100% and the energy efficiency is high.

6.Compared with ordinary motors, the two-stage compression permanent magnet variable frequency air compressor has a permanent magnet synchronous motor with rapid load response, precise control, and fast response speed. It can adjust the gas production in a wide range in an instant, making the air pressure truly constant.

Super large displacement beyond the same level

The two-stage compression permanent magnet variable frequency air compressor provides the highest level of displacement in the industry. The ultra-large displacement host and the same power air compressor have a much larger displacement than the previous year. The abundant and majestic displacement provides sufficient compressed air for your industrial production. For example: a two-stage compression 90kW air compressor can easily replace an ordinary 110kW air compressor.

Highly efficient and energy-saving, surpassing the national first-level energy efficiency

The two-stage compression permanent magnet variable frequency air compressor passed the energy efficiency test with a score exceeding the national standard by nearly 6%. It also obtained the energy-saving catalog certification of the Ministry of Industry and Information Technology and successfully obtained the National Energy Efficiency Star logo. For a user who uses it for 8,000 hours a year, using a two-stage compression permanent magnet variable frequency air compressor, if the user's local electricity bill is 0.8 yuan per kilowatt hour, the same power will be higher than that of an air compressor that has just crossed the first-level energy efficiency threshold. If the machine is installed, the two-stage compression permanent magnet variable frequency air compressor can save up to 60,000 yuan in electricity bills every year. Under the same power, an ordinary second-level energy-efficient air compressor can save up to 80,000 yuan in electricity bills every year!

Rugged, ultra-reliable permanent magnet motor

The two-stage compression permanent magnet variable frequency air compressor uses a high-efficiency permanent magnet motor with a speed of 1500 rpm, low speed, ultra-high torque, low noise, and ultra-long life. The liquid cooling system independently designed by Inspur, the two-stage compression permanent magnet variable frequency air compressor is cooled by low-temperature coolant, and the innovative design ensures that the permanent magnet motor will never lose magnetism.

Although the two-stage compression permanent magnet variable frequency air compressor is more expensive than other types of air compressors, it is considered from the perspective of our long-term use. Although the machine we bought is expensive, it is very energy-saving and can help us save a lot of electricity bills. Therefore, it is more cost-effective to choose a two-stage compression permanent magnet variable frequency air compressor.

A screw air compressor is a type of air compression equipment commonly used in industrial and commercial applications. As a new type of air compressor, it is more convenient to operate than traditional piston air compressors, not only because of its stable performance, but also because of its low vibration frequency and low noise, so there is no need to worry about piston noise. Their main purpose is to compress a large amount of air into a smaller volume and provide high pressure and high flow rate of compressed air.

 

The purpose of using a screw air compressor is as follows

 

1. Providing power: Screw air compressors are the power source for many industrial equipment and tools, such as pneumatic tools, spray painting equipment, refrigeration equipment, etc. They compress air to high pressure and then pipe it to equipment that requires compressed air for power.

 

2. Store energy: An air compressor can store compressed air in an air tank for emergency use. This method of storing energy can cope with peak gas consumption and sudden gas consumption, providing a stable and continuous supply of compressed air.

 

3. Processing and production: Screw air compressors play a key role in many production processes. They are used in gas separation, pipeline transportation, material transportation and other processes to provide stable compressed gas and play a vital role in many industrial fields.

 

Screw air compressors can also be integrated with other equipment and systems, such as cooling systems, air conditioning systems, pumping stations, etc., to achieve wider applications and benefits. The most important thing is that the screw air compressor can have continuous trouble-free movement, long service life, and simple maintenance, which can save more maintenance costs.
