Medium Size Oil Lubricated Screw Air Energy Saving 50 Hp Screw Compressor

Product Specification

Why the electric oil-lubricated rotary screw air compressor becomes more and more popular?

1. High reliability: The screw air compressor has few parts and wearing parts, reliable operation and long service life.
2. Simple and convenient operation and maintenance: gas can be supplied according to the required displacement.
3. Good power balance: the screw air compressor has no unbalanced inertial force, and the machine runs smoothly at high speed. It is especially suitable for use as a mobile compressor, with small size, light weight and small footprint.
4. Strong adaptability: The screw air compressor has the characteristics of forced air delivery, the displacement is basically not affected by the exhaust pressure, the operation is stable, the vibration is small, and the exhaust is stable.
5. Multi-phase mixed transmission: There are gaps between the rotors of the screw air compressor, which can withstand the impact of liquid, and can also send out liquid-containing gas, dust-containing gas, and polymerized gas under pressure.
6. The unit exhaust volume is small and occupies a small area.

Machine Details&Features:

1.High Efficiency Permanent Magnet Motor
Protection class IP54, insulation class F high protection, high precision, adjustable, low noise, low vibration, stable operation.

2.Smart Inverter
Intelligent frequency conversion start, stable air pressure, start without impact.

3.Efficient Screw Airend
High-precision twin-screw rotor, triple-glazed, less wearing parts, compact structure, large air delivery, high stability.

4.Intelligent PLC Control System
Record equipment operating status, automatically remind equipment repair and maintenance, automatic fault alarm shutdown protection, real-time intelligent detection of compressor status.

5.Intake Valve Assembly
The air intake valve can automatically adjust the air volume from 0 to 100% according to the requirements of the system air volume, and the pressure loss is small.

The energy saving effect of permanent magnet variable frequency air compressor:

1. The biggest feature of the permanent magnet variable frequency air compressor is energy saving. Generally, the energy-saving effect reaches 8% and above. 

2. Stable air pressure Since the variable-frequency screw air compressor utilizes the stepless speed regulation characteristics of the frequency converter, it can be started smoothly through the controller or the PID regulator inside the frequency converter. Quick adjustment response.

3. The shaft transmission efficiency of the host and the motor is 100%, no coupling, no gear, no belt drive. Permanent magnet motors do not require bearings, maintenance, and lubricants, eliminating failure points and reducing maintenance costs. Ordinary asynchronous motors often suffer from bearing wear and lead to coil burning and other faults, and the maintenance cost is high.

4. No shock current at start-up The inverter itself covers the function of soft start, the maximum start-up current is within 2 times of the rated current, and the start-up shock is very small. The power frequency start is generally more than 6 times the rated current. When the capacity of the factory power grid is limited, it will cause the air compressor switch to trip. Not only the impact on the grid, but also the impact on the entire mechanical system is greatly reduced.

5. Variable flow control Ordinary industrial frequency air compressors can only work at one displacement, while permanent magnet variable frequency air compressors can work in a wider range of displacement. According to the actual air consumption, the motor speed is automatically adjusted in real time to control the exhaust volume. How much gas is used to produce as much gas, and the air compressor can be automatically dormant when the gas consumption is low, greatly reducing energy loss.
