Product Description

LG-II series two-stage air compressor

Product Description

Main Machine:

1. Adopt two-stage compression main engine, large rotor and low speed.
2. The upper and lower integrated design concept combines the first-stage compression rotor and the second-stage compression rotor in one casing to achieve the highest compression transfer efficiency.

      3. The compression ratio of each stage is small, the leakage is smaller, and the volume utilization rate is high. The bearing is less stressed and has a long service life.



Intake system:
Vertical straight-through air intake structure minimizes pressure loss, special air inlet sealing material ensures long service life, no wearing parts, reliable performance and long service life.

Piping system:
The pipeline system adopts the American standard pipeline design. Due to the large inner diameter of the transport pipe and the small flow resistance, the hard pipe usually has a higher transport rate than the hose, and is stable, long service life, and maintenance-free for life.

Permanent magnet motor:
The variable frequency permanent magnet motor has the characteristics of high efficiency, high power factor, wide high efficiency interval, stable speed, zero slip, and energy saving. Therefore, the permanent magnet frequency conversion equipment under the two-stage screw compressor can be more energy saving.

Controller:

1. Adopt advanced microcomputer control to achieve intelligent operation and humanized operation, and the operation status is clear at a glance.

2. Equipped with advanced intelligent control system, various parameters such as pressure and temperature are continuously monitored, controlled and displayed according to preset values.
3. It has the function of automatic fault alarm and protection, and stores historical operation records in time.

Product Feature
Energy saving analysis

1. The compression ratio of each stage is much smaller than the compression ratio of the common main engine of the same power, and by oil injection cooling, the temperature of the secondary intake air is reduced, and the compression work is greatly reduced.
2. The low pressure ratio greatly reduces the backflow leakage between the rotors, and greatly improves the volumetric efficiency and adiabatic efficiency, which is ultimately reflected in the increase in the compressed gas production.
3. Two-stage compression is better than single-stage at the same power.
