Customized Turbo Centrifugal Vacuum Pump - the Great Tool for Paper
Making Machinery Plant to Save Power
Description
GoodSeaA high-speed variable frequency centrifugal vacuum pump
adopts aerodynamic technology and aviation-grade processing and
manufacturing process, it is designed for the papermaking and
chemical industries. The impeller adopts aviation-grade
high-strength alloy material, which can be used 300,000 hours
(about 35 years) without maintenance. It’s drive system uses
high-efficiency and energy-saving motors, the quality is stable and
reliable, It is suitable for long-term stable operation in harsh
environments such as high temperature and high humidity.
According to the characteristics of papermaking industry, the
impeller of the centrifugal vacuum pump is specially made of
aviation-grade high temperature-resistant and high strength alloy
material, abrasion resistance, corrosion resistance, white water
droplets resistance and pulp fiber impact resistance, able to provide 30 years of service, impeller maintenance free.
In the process of design and R&D, special attention is paid to
the high performance, high reliability and high cost performance of
the product.
Compared with the advanced turbine vacuum pump abroad, the
transformation cost can be saved by more than 50% for machines of
the same power.
Unique advantage of GoodSeaA Centrifugal Vacuum Pump System
GoodSeaA centrifugal vacuum pump adopts variable frequency
technology, which can adjust the speed of vacuum pump, adjust the
power with the change of parameters of paper production line, and
keep vacuum pump always working in the best operating condition.
GoodSeaA vacuum system is a completely customized design. The most
reasonable vacuum point design is selected according to the user's
paper machine operation. The vacuum degree proximity point, suction
point is combined to make the high-speed centrifugal vacuum pump
efficient and always run at high-efficiency zone of the pump’s and
the motor’s characteristic line, it is equivalent to the aircraft
flying at the most fuel-efficient cruising speed.
GoodSeaA centrifugal vacuum pump has three centrifugal pumps:
single-stage, two-stage and three-stage. One equipment has multiple
suction ports and can pump two different vacuum degrees. Therefore,
a high-speed centrifugal vacuum pump can replace multiple water
ring vacuum pumps, it has compact structure and many adjustable
output parameters.
GoodSeaA vacuum system provides complete equipment and system
solutions: including water-air separator, cooler, filtrate pump,
silencer, valves, meters, fittings and fully automated control
systems for online monitoring of vacuum degree and pumping flow.
Strength checking method
- Using Finite Element Analysis (FEA) software, such as NASTRAN,
ANSYS and Abaqus to check the strength of the impeller and blade,
through the simulation, the stress and displacement distribution
data of each part are obtained, and then the impeller design is
judged to meet the requirements of the aero engine safety design
standard or not, and the service life is also predicted.
Dynamic Optimization of Aviation Rotor Structure
- Changing the stiffness/mass distribution of the rotor,
concentrating the vibration energy adjustment of the rotor at the
support position, and dissipating the vibration energy through the
rotor damper at the support.
- Through the optimum design of the support stiffness, the bending
critical rotational speed with greater harm is adjusted to the
maximum working speed, and sufficient margin is guaranteed.
