7.5KW Vsd Screw Type Air Compressor Oil Lubricated Direct Drive

Product Specification

VSD Inverter Screw Compressor Oil Lubricated Direct Drive Combined For Laser Cutter

The permanent magnet variable frequency screw compressor is a new type of equipment compatible with the current mainstream. The traditional screw compressor not only consumes fuel, but also consumes a lot electricity.

The permanent magnet variable frequency air compressor is energy-saving and efficient and has become a hot spot and highlight in the industry. The original air compressors with large power consumption in the market are gradually being replaced by permanent magnet variable frequency air compressors, which can directly bring users 20% -40% cost savings!

PM Motor VSD screw air compressor is widely used in various industries. LTC Compressor developed combined screw air compressor specially for metal laser cutting industry. 7.5KW~22KW are available, bule and orange machine outlook optional, OEM service is also accepted.

Why choose LTC Compressor's All In One design tank mounted screw air compressor?

1.Intelligent PLC Control System
Realize the remote control of the screw compressor.

2.Efficient Screw Airend
High-precision twin-screw rotor, triple-glazed, less wearing parts, compact structure, large air delivery, high stability.
HANBELL or BAOSI brands are available, both high quality air end in China.

3.High-Precision Filters
Ensure clean air, prolong the life of the screw airend, extend maintenance cycle.

4.Air Receiver Tank
Large capacity, energy saving, thickened material, cushioning, cooling, water removal, pressure stabilization.

5.Oil and gas separator
It adopts a huge oil and gas separator. After a three times' deep bed filtration, the oil volume is less than 3ppm and the pressure loss is only 0.02Mpa. With the reduction of oil mist exhaustion, the running cost of downstream equipment is increasingly lessen.

6.Intake Valve
None is easily damaged with an ON-OFF regulation and the adjusting range of tidal volume is 0 to 100%. It has small pressure loss and long operating life. At present, it is the most effective and reliable adjusting method of intake.

Advantages of Frequency Conversion Screw Air Compressor:

1. The air pressure of the permanent magnet variable frequency air compressor is stable

Since the variable frequency screw air compressor utilizes the stepless speed regulation feature of the frequency converter, it can be started smoothly through the controller or the PID regulator inside the frequency converter; it can also quickly adjust and respond to occasions with large fluctuations in air consumption. Compared with the upper and lower limit switch control of power frequency operation, the air pressure stability is improved exponentially.

2. The permanent magnet variable frequency air compressor starts without impact

Since the frequency converter itself has the function of a soft starter, the starting current is within 1.2 times of the rated current. Compared with the power frequency starting, which is generally more than 6 times of the rated current, the starting impact is very small. This kind of impact is not only on the power grid, but also on the entire mechanical system, which is also greatly reduced.

3. Variable flow control of permanent magnet frequency conversion air compressor

The air compressor driven by industrial frequency can only work in one displacement, and the variable frequency air compressor can work in a wider range of displacement. The frequency converter adjusts the motor speed in real time according to the actual gas consumption to control the exhaust volume. When the air consumption is low, the air compressor can also be automatically dormant, which greatly reduces energy loss. The optimized control strategy can further improve the energy saving effect.

4. The voltage adaptability of the AC power supply of the permanent magnet variable frequency screw air compressor is better

Due to the overmodulation technology adopted by the frequency converter, it can still output enough torque to drive the motor when the AC power voltage is slightly low; when the voltage is slightly high, it will not cause the output voltage to the motor to be too high. For self-generating occasions, variable frequency drive can show its advantages. According to the characteristics of the VF of the motor (variable frequency air compressors work below the rated voltage in the energy-saving state), the effect is obvious for the site with low grid voltage.

5. Permanent magnet variable frequency energy-saving air compressor with low noise

Most of the working conditions of the frequency conversion system work at lower than the rated speed, the mechanical noise and wear of the main engine are reduced, and the maintenance and service life are extended. If the fan is also driven by frequency conversion, it can significantly reduce the noise of the air compressor when it is working.
