3、Core technology advantages

3.1、Efficiency Compressor Airend

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 meshing. Design with large diameter and low speed, equipped with heavy-duty SKF bearings and three special oil seals to ensure the highest gas production efficiency and life time.

Optimization the rotor tooth shapeThe tooth shape is a key factor affecting the efficiency of gas production. The solution to this problem lies in the technology of the shape. Through years of experience and verification, we have a plan to optimize and improve the shape of the tooth root.
Reform of the mesh and sealReform the mesh and seal of the bottom line of the rotors, reduce the problem of the leakage, and raise the volume efficiency.
Reform of lengthdiameter ratioImprove the length: diameter ratio of the double screw rotors. Raise the integral rigidity of rotors by shorten the distance between two bearings, to achieve higher volume efficiency under higher pressure, greatly decrease vibration, reduce noise, and extend the machine’s useful life.
Optimization the rotor axial distance Increase the effective cross-sectional area of compressor rotor and the axial distance between the two shafts to maximize the utilization factor of rotor area, reserve enough space for the installation of larger diameter bearings, and fundamentally solve the failure factor of bearing wear after years.

3.2、High energy-saving centrifugal cooling system (Patent No.:CN201320374179.8)

For a long time, the cooling mode of air-cooled high-power compressor mostly uses a number of common axial fans installed in the unit interior to exhaust wind outside. The fan sucks the hot air inside the unit and then cools the heat exchanger, it is difficult to achieve the best cooling effect, and therefore, air-cooled high-power units have always been a chronic disease in the air compressor industry.

SUCCESS ENGINE’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.

Independent enclosed side suction cooling structure

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.
