280kw 7 - 13bar Variable Frequency VSD Two Stage Screw Air Compressor
1. What is Two Stage Compressed Air Technology?
Unlike a conventional single stage compressor, a two-stage air compressor divides the overall compression ratio between two distinct airends. This has the effect of significantly reducing internal leakage losses resulting in substantial efficiency gains as well as extending bearing life due to reduced applied loads.
GoodSeaA two stage air compressors require a smaller drive motor to produce the equivalent volume flow rate to that of a comparable single stage compressor.
2. Why is it much more efficient?
These remarkable efficiency savings are achieved through reduced leakage losses across each stage, optimised cool oil injection and enhanced airend geometry.
You could save in excess of 50% of your compressed air energy bill.(Compared to an equivalent single stage fixed speed compressor).
3. Advantages of GoodSeaA Two Stage Screw Air Compressor
Excellent Powerful Compressor Airend (Patent No.:CN201320374188.7)
GoodSeaA two-stage screw air compressor airend adopts a new pattern of rotor, by optimizing the bottom line of the rotor, to improve the effective volume and sealing efficiency of the compressor, making the contact line length, leakage triangle area and closed clearance volume between the three to achieve optimization, thoroughly resolving the leakage of oil and gas mixture during rotor meshing. The design with large diameter and low speed, equipped with heavy-duty SKF bearings and three special oil seals, to ensure the gas production highest efficiency and life time, and greatly reduced radial tremor and airflow noise.
High Energy-saving Centrifugal Cooling System (Patent No.:CN201320374179.8)
GoodSeaA’s patent (a high energy-saving centrifugal cooling system) adopts the latest variable frequency centrifugal cooling structure, and uses aero-dynamics impeller ternary simulation software NUMECA to carry on the aerodynamic calculation and the full three-dimensional flow field simulation, simulates the actual operation to optimize the worm shell structure and the rotor type, to save the power, increase the dynamic pressure and achieve the optimal fan efficiency.
The aluminum plate-fin heat exchanger is installed on the suction end of the external fan of the unit to form an independent closed cooling system structure. The variable frequency speed control technology is used to automatically adjust the fan speed according to the system temperature change, change the air volume, and greatly save cooling energy consumption. It can reduce noise and completely overcome the problem of poor cooling effect of air-cooled high-power air compressor equipment.
