Technical advantages of Schneider single-screw air compressor:
In addition to the inherent high reliability of twin-screw compressors, single-screw compressors In addition to the advantages of easy operation and maintenance, strong adaptability, and no inertia, it is a new generation compressor developed after overcoming the design and structural shortcomings of twin-screw compressors. It is the driving force to replace twin-screw compressors with single-screw compressors. The inevitable development trend of using compressors is an inevitable choice for a modern enterprise. Americans say this:
Single screw compressors are strategic products in the 21st century
. The single-screw compressor has the following advantages over other compressors:
, reasonable structure, and ideal force balance
The star wheels are symmetrically arranged on both sides of the screw axis, and the radial forces of the gas acting on the screw interact with each other. The gas bearings acting in the screw groove also cancel each other out, and the screw is in a completely balanced state. Therefore, the bearings of the main engine are not affected by any axial or radial force, and the gas force on the star wheel is also very small, only about that of the piston compressor or twin-screw compressor. Therefore, the bearings of the main engine and the star wheel are long life.
'
, long service life and extremely high reliability.
For the following reasons, it has a long service life (usually more than
years)
The meshing between the screw rotor and the star wheel is compressed into metal and non-metal. The rotor material is made of six-tooth steel coated with aluminum protective layer, and the star wheel is made of eleven-tooth layer reinforced fiber composite reinforced material. Flexible zero-gap contact sealing can be achieved.
(b)
There are very few parts and wearing parts, and there are only five main moving parts, one rotor, two star wheels, and two slide valves.
()
Since the radial and axial forces on the rotor are completely balanced, the radial and axial thrust of the bearing are extremely small, the reliability of the bearing is extremely high, and the design life of the bearing is up to,
hours. It is
~
times that of twin-screw.
'()
'Liquid injection is used instead of oil injection during operation, which has better sealing, lubrication and cooling effects, low meshing resistance, and economical and effective lubrication. The oil-free lubrication method does not require a complicated oil circuit system, only a small amount of refrigeration oil is required, and the oil circuit is simpler than a twin-screw.
,
Inspection is required after 3 hours, and major maintenance is required after 3,
~,
hours. The star wheel can be disassembled separately for easy maintenance.
Because the star wheel is in a flexible bearing state, the gap between it and the main rotor can be adjusted, so it is not sensitive to liquid shock and can operate in wet stroke.
The semi-enclosed single-screw motor is liquid-cooled to maintain a long-term cooling state and the motor has a long life.
Due to the balanced force on the rotor, the shaft seal load is extremely small and has a long service life, which is much higher than the shaft seal life of a twin-screw compressor.
High efficiency.
The
zero-clearance
cooperation between the rotor and the star wheel minimizes leakage loss and pressure loss, and greatly improves efficiency.
(b)
Semi-enclosed single-screw motor is liquid-cooled and has high motor efficiency.

'Single-screw air compressor has high efficiency at medium speed (r/)
, direct connection, specific power./(3/)
And twin-screw air compressor The efficiency of the press is high at high speed (3/)
, with the addition of speed-increasing gear, the specific power is ./(3/)
. Since the six-tooth rotor meshes with the eleven-tooth star wheel, the dispersion and The exhaust pulsation is reduced, thereby making the exhaust smooth, and the alternate meshing effectively eliminates sine wave, so the noise is low and easy to insulate. Generally lower than twin screws of the same grade
~
.
, extremely stable operation, vibration value is lower than
. Twin-screw compressors are significantly higher than this value.
Easy to repair on site, the star wheel can be disassembled from the top or bottom for repair. After the main machine casing adopts an integral structure, there is a large window on the side of the star wheel, which is convenient for maintenance. Currently, only the R series claims that its products are also easy to repair and service.
'Assemblyability: The single-screw air compressor has relatively few parts and can be independently assembled and adjusted before entering the main engine. This is not the case with twin-screw air compressors. The rotor bearing has a heavy load and the structure is complex. A specialized factory is required for assembly and adjustment.
'
', Durability: The radial and axial forces of the single-screw compressor are completely balanced, the bearing life is long, the rotor bearing is
million

The twin-screw air compressor rotor has a large load and the bearing life is short, generally
10,000!

'
', volume structure: the single-screw air compressor has the smallest volume, the box-type sound insulation packaging has a compact structure, and is easy to maintain
The twin-screw air compressor has a small host size, but the drive The space of the device is divided
