Aeroengnine Compressor-Design and manufacture method

One-dimensional geometry and thermal design

Two-dimensional flow design

• Mainly refers to the meridional channel and streamlines design, and the common meridional channel line is Bezier curve.

• The design process focuses on the curvature change of the streamline, the changes of blade mounting angle, or the area shrinkage rate of the path.

• The inlet and outlet mounting angle is given by the preliminary design, while the position and size of the maximum blade mounting angle are adjusted by the designer's experience and simulation results.

Three-dimensional blade design

• The aero engine blades exhibit complex three-dimensional, complex curved geometric features.

• Using previous experience to design, or classic blade design can no longer meet the needs.

• The blade design, modeling and optimization process are mainly accomplished by aero turbomachinery design software.

• The uses of splitter blades (also known as small blades) can not only reduce the blockage of the impeller inlet, but also ensure that the impeller has enough work function.

Three-dimensional flow field simulation

The aerodynamic calculation and full three-dimensional flow field simulation are carried out by using the aviation aerodynamic impeller ternary simulation software NUMECA to simulate the actual operation and provide an important basis for design performance evaluation.

Commissioning & Testing

1. High Speed Dynamic Balance Test

• Gradually balancing from low speed to high speed.

• The equilibrium speed is as close as possible to the critical speed.

• Balance at rated working speed to ensure balance accuracy.

2. Rotor Test

• The wheel rotation fracture test is carried out without damage in the ground with 122% maximum rotational speed.

• Working on the engine at 115% maximum allowable steady-state operating speed for 5 minutes without cracking and the size is within the allowable range.

• On the engine, exceed the maximum allowable average steady-state temperature of 42℃, work for 5 minutes without cracking, and the size is within the allowable range.

3. Vibration Test

• 20% margin between critical speed and maximum working speed.

• During the test of the components and the whole machine, there is no adverse reaction to the vibration in the working speed range.

4. Performance, Characteristic Test

• Performance tests under design conditions.

• ​Characteristic tests under non-design conditions.

• Process the test data to determine whether the performance of the component is up to standard and draw a characteristic curve.

Values Made for Customers

Provide customized design according to user’s paper machine vacuum system, enables the equipment always working in energy-efficiency area, which can save 30-60% energy and 100% water for the papermaking vacuum system. Through the waste heat recovery system, the level of comprehensive energy utilization will be further improved. The investment recovery period is 8-18 months. One unit 500kW centrifugal vacuum pump can at least completely replace the water ring vacuum pump with a total power of 710kW. Each production line can save 200 Thousand Dollars in electricity for cusomters per year.

Saving money means making money. After adopting our company's vacuum pump instead of it’s old water ring pump, one listed papermaking enterprise realized energy saving of 50% and increased production by 20% under the condition that other parts of the paper machine remained unchanged. Our vacuum pump has create the value of 20 Million Dollars every year for this papermaking company.

No need for grid expansion and space saving. With frequency conversion starting, and there is no impact on the power network. Compared with traditional vacuum systems, this equipment saves more than half of space.
