Custom Centrifugal Vacuum Pump / Blower Vacuum Pump For Paper Making Machinery

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.
