Avantajele Lingyu 22 kw 30 hp Screw Air Compressor
(1) High Quality Screw Compressor Airend
The whole series of rotors are processed by grinding machines imported from Germany. It has high precision and high efficiency. Because of the large diameter rotor, the speed is lower. The overall structure is more compact and beautiful. The airend and motor are easy to install and disassemble. in afara de asta, our airend adopts original SKF heavy-duty bearings. Reduce noise and prolong service life. So the maintenance costs are low. The lifetime of our airend is more than 100,000 ore. în plus, the transmission efficiency is high.
(2) High Temperature Resistant Permanent Magnet Motor
The motors of our 30 hp air compressor are available in IP23 and IP54 options. în plus, the permanent magnet motor has an important performance index. That is a high-temperature resistance grade. If exceeds its temperature rating, its magnetic flux density drops sharply. We use 38UH permanent magnets. Temperature resistance up to 180°C.
(3) Inovance Frequency Inverter, More Energy-saving
The difference in energy saving between VSD air compressor and fixed speed air compressor: The latter uses the intake valve to adjust the intake air demand. But the former is different. It uses motor frequency conversion to adjust. The difference in energy saving between the two is as follows:
Assumptions: 70% average load. And it runs for 8,000 hours per year. The electricity fee per degree (kw/h) is 0.7CNY. The power frequency screw compressor is generally set. When the variable speed drive air compressor reaches the minimum frequency, it will turn to standby mode.
Energy-saving calculation: save energy consumption of idling operation + energy consumption for energy-saving loading process. Compared with the latter, the annual energy-saving amount of the VSD screw compressor is as follows:
| Screw Compressor | 22kw | 30kw | 37kw | 55kw | 75kw | 90kw | 110kw |
| Putere | |||||||
| Saved Electricity | CNY22669 | CNY30912 | CNY38125 | CNY56672 | CNY77282 | CNY92736 | CNY113344 |

If the air consumption (%) of the two types of air compressors is stable at 50%, the energy-saving ratio of the VSD screw compressor is about 23%. If the air consumption fluctuates more or the air consumption (%) is lower, the energy-saving benefit of the VSD air compressor will be greater than 23%.
Prin urmare, VSD screw compressors are suitable for factories with large fluctuations in air demand. Manufacturers can consider using several power-frequency air compressors with one variable-frequency air compressor. In this way, the overall benefit will be more economical and energy-saving.
(4) Integrated Intake Valve
Air intake adjustment range 0~100%. The pressure loss is small. Printre ei, the key parts of solenoid valves are internationally renowned brands. So it guarantees the absolute operation safety of the 22kw air compressor. în plus, the intake valve has the function of unloading and supplementing air. Prin urmare, it can effectively eliminate the cavitation noise generated by the airend.
(5) High Quality Spare Parts And Consumables
The 30hp screw air compressor uses the fin-type cooler. It has a large heat exchange area. And the heat exchange surplus is 30%. So the cooler works well. in afara de asta, it can work normally at an ambient temperature of 45°C. We use the Shell lubricant oil. It has good oxidation resistance and anti-emulsification performance. So the service life is long.
Întrebări frecvente
Î1: How many CFM is a 22kw 30 HP screw air compressor?
A1: This is a small airflow industrial air compressor. The greater the air pressure, the smaller the air capacity. When air pressure is 7 bar, fluxul de aer al 22 kw compressor is about 3.8m³/min. Acesta este, 130 cfm. And when air pressure is 12 bar, the air capacity is about 2.9m³/min. It’s about 90 cfm.
Q2: How long is your 30hp air compressor warranty?
A2: All our industrial screw compressors have the same warranty time. The whole air compressor machine is one year old. And the warranty time of the airend and motor is two years. We recommend purchasing some consumable spare parts, such as three compressor filters and valves.
Q3: Do I also need to buy the compressed air dryer?
A3: This is based on your specific industry application requirements. If your compressed air dew point is 3~10℃, then it only needs a refrigerant dryer. But if you need a lower dew point, there must be a desiccant air dryer. Desigur, it usually also needs to install the 3-stage coalescing filters.
Î4: How much HP do I need for a screw air compressor?
A4: In fact, this depends on the air consumption of your plant. Different industrial compressor powers (HP), and different air capacities. De exemplu, the air capacity of a 30 hp air compressor is 3.8m³/min. And pls contact us for selection.
Î5: How often do I change the three kinds of air compressor filters?
A5: The first filter maintenance is 500 hours of work. In the future, it is recommended to replace it after working for 2000 ore.
Î6: What’s the working principle of the automatic start and stop of a VSD screw air compressor?
The variable frequency screw compressor will automatically unload when it reaches the set air pressure. Momentan, the intake valve will close. But the motor will still run at low speed. When the air consumption does not fall below the set minimum pressure within the set time, the motor will stop. Conversely, when the pressure is lower than the minimum, the intake valve will automatically open. Then the motor starts to run.
Q7: What is the amount of lubricating oil for your 22KW air compressor?
A7: The lubricating oil for a 30 hp rotary screw air compressor is 13L.
