What is vsd Air Compressor?
It’s also namely PM VSD screw air compressor. That is the permanent magnet variable frequency compressor. Во-первых, it can change the rotational speed of the drive motor. Во-вторых, adjust the compressor airend speed. Окончательно, 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. Окончательно, it achieves the desired balance. Например, the air consumption reaches the upper limit of the exhaust volume. В это время, the vsd compressor is running at full load.
Напротив, the air consumption is less than the rated volume. В это время, the inverter reduces the frequency of the motor. Thereby reducing the airend speed accordingly. В конце концов, it reduces the air discharge volume. When stopping air usage, the variable frequency motor runs at a low frequency. В то же время, 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;
- В то же время, improve the working efficiency of the screw air compressor.
2. Permanent Magnet Variable Frequency Motor
It maintains very high motor efficiency at low speeds. Поэтому, 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%. Более того, 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. Кроме, has a wider speed regulation range.
Кроме того, the permanent magnet motor uses NdFeB permanent magnets. So it will not lose magnetism at 120°C. The service life can be over 15 годы.
3. Smart Control Panel
Таким образом, it brings many advantages of our screw air compressor for sale.
- Improve the interactive experience of compressor operator;
- Кроме, support various mainstream PLC communication protocols;
- And it can smoothly support animation and video playback;
- Кроме того, faster data processing and response speed.
4. Super Filtration System
- Use precise oil and air separation filter elements;
- Improve the compressed air separation efficiency;
- Более того, reduces the exhaust oil content;
- В то же время, prevent pipeline blockage.
Часто задаваемые вопросы
1. Why has my screw compressor stopped working?
The following reasons may cause vsd air compressor to stop suddenly.
Во-первых, the exhaust temperature of the screw air compressor for sale is high.
Во-вторых, the unloading valve is faulty.
в-третьих, the airend resistance is too large.
Кроме того, 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.
Для бывшего, it only needs to replace the air compressor oil and oil filter. В целом, it is replaced when the new compressor runs for 500 часы.
Для последнего, also needs to replace the air filter and the oil-air separator element. Также, replace the motor grease, и т. д.. Usually carry out this maintenance when the compressor is running for about 3000 часы.
Конечно, 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. Поэтому, the cost is low.
Однако, 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.
