Details: Permanent magnet screw compressor


 



The difference between variable frequency air compressor and ordinary air compressor



 



1. Stable air pressure: (1) Since the frequency conversion screw air compressor takes advantage of the stepless speed regulation feature of the frequency converter, it can start smoothly through the controller or the PID regulator inside the frequency converter; it has relatively large fluctuations in air consumption. situation, and can quickly adjust the response; (2) Compared with the upper and lower limit switch control of power frequency operation, the air pressure stability is improved exponentially



 



2. Start without impact: (1) Since the frequency converter itself contains the function of a soft starter, the starting current is within 1.2 times of the rated current. Compared with power frequency starting, which is generally more than 6 times of the rated current, the starting impact is very small. Small. (2) This impact not only on the power grid, but also on the entire mechanical system is greatly reduced. ​



 



3. Variable flow control: (1) The industrial frequency driven screw air compressor can only work at one displacement, while the variable frequency screw air compressor can work at a wider range of displacement. The frequency converter adjusts the motor speed according to the actual air consumption to control the exhaust volume. (2) When the air consumption is low, the air compressor can automatically sleep, thus greatly reducing energy loss.



 



4. The voltage adaptability of the AC power supply is better: (1) The frequency converter adopts over-modulation technology, which can still output sufficient torque to drive the motor when the AC power supply voltage is slightly lower; when the voltage is slightly higher, it will not cause output The voltage to the motor is relatively high; (2) For the occasion of self-generation, variable frequency drive can better show its advantages; (3) According to the characteristics of the motor VF (variable frequency screw air compressors work below the rated voltage in the energy-saving state), For sites with low grid voltage, the effect is obvious.



 



5.Low noise: Most working conditions of the frequency conversion system work below the rated speed. The mechanical noise and wear of the host machine are reduced, and maintenance and service life are extended.

Screw compressors are the core equipment of modern industrial production and are widely used in petrochemical, coal chemical, natural gas, metallurgical, electric power, machinery manufacturing and defense industries. In addition, the demand for screw compressors in the medical, textile, food, agriculture, transportation and other sectors is also increasing day by day. The screw compressor can provide power source for pneumatic equipment, and can also be used to increase gas pressure or transport gas. Especially in petroleum and chemical production, the screw compressor is an indispensable key equipment. Various gases pass through the screw compressor. After the compressor increases the pressure, it generally has the following uses:



1. The compressed gas produced by the screw compressor can be used for refrigeration and gas separation.



The gas is compressed and cooled to liquefy it and is used for artificial refrigeration. This type of compressor is usually called an ice maker or ice machine. If the liquefied gas is a mixed gas, each component can be separated separately in a separation device to obtain various gases with acceptable purity. For example, in the separation of petroleum cracked gas, it is first compressed and then each component is separated at different temperatures.



 



2. The compressed gas produced by the screw compressor can be used as power



After being compressed, air can be used as power to drive various pneumatic machinery and tools, as well as control instruments and automation devices.



 



3. The compressed gas produced by the screw compressor can be synthesized and polymerized



In the chemical industry, the pressure of certain gases increased by a compressor is beneficial to synthesis and polymerization. For example, nitrogen and hydrogen synthesize ammonia, hydrogen and carbon dioxide synthesize methanol, carbon dioxide and ammonia synthesize urea, etc. Another example is the production of polyethylene under high pressure.



 



4. The compressed gas generated by the screw compressor can transport gas



Screw compressors are also used for gas pipeline transportation and bottling, such as remote gas and natural gas transportation, chlorine and carbon dioxide bottling, etc.
