What is vsd Air Compressor?
It’s also namely PM VSD screw air compressor. That is the permanent magnet variable frequency compressor. Pertama, it can change the rotational speed of the drive motor. Kedua, adjust the compressor airend speed. Akhirnya, adjust the air discharge volume.
The air capacity of vsd rotary screw compressor can be adjustable by itself. That is changed according to the customer’s on-site air consumption. Air demand changes the speed of the motor. Akhirnya, it achieves the desired balance. Misalnya, the air consumption reaches the upper limit of the exhaust volume. Pada saat ini, the vsd compressor is running at full load.
Di sisi lain, the air consumption is less than the rated volume. Pada saat ini, the inverter reduces the frequency of the motor. Thereby reducing the airend speed accordingly. Pada akhirnya, it reduces the air discharge volume. When stopping air usage, the variable frequency motor runs at a low frequency. Pada saat yang sama, the intake valve does not take in air. The screw compressor is in a no-load state.
Why Choose Lingyu Variable Frequency Air Compressor?
1. High Efficiency Screw Airend
- Adopt Sweden’s top SKF tapered roller bearings;
- Reduce the exhaust pressure resistance;
- Lower rpm, big air end, and big discharge air volume;
- Ensure high performance of vsd compressor;
- Pada saat yang sama, improve the working efficiency of the screw air compressor.
2. Permanent Magnet Variable Frequency Motor
It maintains very high motor efficiency at low speeds. Karena itu, when the air consumption is small, it has obvious energy-saving advantages. Compared with fixed-speed air compressors, the energy saving is 15%~38%. Compared to ordinary VSD air compressors, energy saving is 5%~10%. Lebih-lebih lagi, the greater the fluctuation of air consumption, the more obvious the energy-saving effect. So our industrial air compressor machine has a high overload capacity. Di samping itu, has a wider speed regulation range.
Selain itu, the permanent magnet motor uses NdFeB permanent magnets. So it will not lose magnetism at 120°C. The service life can be over 15 bertahun-tahun.
3. Smart Control Panel
Dengan demikian, it brings many advantages of our screw air compressor for sale.
- Improve the interactive experience of compressor operator;
- Di samping itu, support various mainstream PLC communication protocols;
- And it can smoothly support animation and video playback;
- Selain itu, faster data processing and response speed.
4. Super Filtration System
- Use precise oil and air separation filter elements;
- Improve the compressed air separation efficiency;
- Lebih-lebih lagi, reduces the exhaust oil content;
- Pada saat yang sama, prevent pipeline blockage.
FAQ
1. Why has my screw compressor stopped working?
The following reasons may cause vsd air compressor to stop suddenly.
Pertama, the exhaust temperature of the screw air compressor for sale is high.
Kedua, the unloading valve is faulty.
Ketiga, the airend resistance is too large.
Selain itu, the thermal relay circuit is short-circuited or has poor contact.
2. How often should compressors be serviced?
For a new vsd air compressor, it is necessary to carry out routine maintenance after use for some time. Maintenance is divided into small and major maintenance.
For the former, it only needs to replace the air compressor oil and oil filter. Umumnya, it is replaced when the new compressor runs for 500 jam.
For the latter, also needs to replace the air filter and the oil-air separator element. Juga, replace the motor grease, dll.. Usually carry out this maintenance when the compressor is running for about 3000 jam.
Tentu saja, it depends on the work environment. If it’s very dirty, should reduce time appropriately.
3. Difference between single screw and twin screw compressor
They have multiple differences.
① Manufacturing costs different
Single screw air compressors can withstand ordinary bearings. Karena itu, the cost is low.
Namun, the latter uses two screws. Because of the large load on the rotor and the high precision, the cost is high.
② Different applicability
Single screw air compressor: suitable for occasions with high exhaust pressure.
The two screw air compressor for sale: It can only be suitable in the medium and low pressure range. Because there are constraints such as rotor stiffness and bearing compliance.
