Why Choose Lingyu Industrial Screw Style Air Compressor
- Firstly, the electric rotary screw air compressor adopts a high-quality airend. The airend is the best Hanbell brand in China. It has excellent rotor linearity. Moreover, the airend has little vibration and low noise. And it uses top-quality and durable SKF bearings. So the operation is more stable.
- Secondly, low-speed motors use high-strength Ru-Fe-B magnets. When the motor starts, the torque is large. The air compressor motor has good insulation performance. It has low noise and low vibration. Besides, it’s with phase sequence protection. So can prevent the motor from reversing.
- Thirdly, our screw style air compressor adopts a quality oil-air separator. It is resistant to high pressure and high temperature. Air filters can filter out tiny solid particles in the air. So as to ensure the normal operation and service life of the equipment.
- The air compressor is with an advanced air volume regulating intake valve. It accepts microcomputer control system instructions. Thus, execute precise adjustment of exhaust volume.
- The screw type air compressor has a humanized LCD display interface. Therefore, the operation is convenient. It can automatically monitor the operating conditions and parameters of the air compressor. 24 hours automatic work under unattended.
- Finally, the cooler adopts an advanced guide design, making the cold and heat exchange more complete. The outlet compressed air temperature is only 15°C higher than the ambient temperature. Meet various working conditions of users.
How Does A Screw Style Air Compressor Work
Electric rotary screw air compressor belongs to positive displacement compressors. It achieves air compression by gradually reducing the working volume.
Its working volume is composed of a pair of intermeshing rotor cogs and a casing. When the machine is running, the teeth of the two rotors are inserted into each other’s tooth slots. As the rotor rotates, this volume progressively decreases, and the pressure gradually increases. This process is done until it reaches the required pressure. At this time, the alveolar side communicates with the exhaust port. So it achieves the air exhaust.
With the operation of screw style air compressor, the suction volume continues to expand. At the same time, the volume of the compressed air is continuously reduced. Thereby, it realizes the suction compression process in each tooth slot. The compressed air pressure reaches the required exhaust pressure in the tooth groove. At this moment, the alveolar just in time communicates with the exhaust port. The venting process begins. The change of suction volume and compression volume is repeated. In this way, the compressor can continuously inhale, compress, and exhaust.
Electric Rotary Screw Type Air Compressor vs Piston
① Different Composition
Screw style air compressor composes of several parts. That is, screw airend, motor, air and oil filter, oil-air separator, refrigeration system, and automatic control system, etc. A piston air compressor generally contains an air storage tank. It does not contain the airend, oil filter, and oil-air separator.
② Different Performance
The electric rotary screw air compressor has many advantages. The vibration is small, low noise, and high efficiency. The exhaust pressure is stable. It is generally fixed. But the piston air compressor is different. The rated power of the motor is usually high. The working pressure of the exhaust pipe is not stable, exhaust temperature is high. Besides, its noise is too loud. In addition, piston air compressors are generally movable.
③ Different Common Problems
There are fewer common problems with screw style air compressors. Just do the maintenance on time. For example, replace the filter element, oil filter oil-air separator, etc. However, the failure rate of the piston air compressor is relatively high. For example, cylinders, pistons, and piston rings are prone to wear and tear.
FAQs
