275 m³/min High-tech Power-saving Centrifugal Vacuum Pump for Chemical Industry
Description
GoodSeaA centrifugal vacuum pump system means advanced aeroengine technology is applied to civil equipment, in the process of design and processing, machines are full of the characteristics of aviation high-tech elements.
GooDSeaA High-speed Variable frequency centrifugal vacuum pump which is composed of special frequency converter and Impeller made of aviation grade high strength alloy material that can serve 30 years without repair and maintenance, using high efficiency and energy saving motor to drive gear, is suitable for long-term operation in high temperature, high humidity and other harsh environments.
GDV vacuum pump’s characteristics of high efficiency, energy saving, stable and reliable, is exactly perfect for papermaking industry, chemical industry and sugar industry, it is a great energy-saving substitute for water ring vacuum pump! Our machine's super high cost performance makes it the most fearful rival of other companies' turbine vacuum pumps!
Advantages of centrifugal vacuum pump compared with water ring vacuum pump
Centrifugal vacuum pump works without water and achieve suction sealing by itself, therefore, the water and the electricity in the water supply system are both saved. See below chart.
While water ring vacuum pump has the following natural defects
When the blade is in direct contact with white water, there is cavitation problem in the blade, white water impurities cause equipment scaling, reduce suction capacity, and increase energy consumption, white water impurities are also easy to cause rotor and pump body lock, bearing, shaft head wear and other problems which lead to high failure rate of equipment, frequent maintenance, high maintenance cost and short service life. Below chart indicates that the performance of water ring vacuum pump decreases with the service life increasing. The impeller wear increases leakage, decreases vacuum and reduces efficiency.
Process optimization
The optimization process requires rapid integration and coupling of design and simulation software in a building block, organizing all design processes into a unified logical framework.
Automate the simulation software and automatically restart the design process to eliminate repetitive work in traditional design processes, enabling the entire design process to be fully digitized and fully automated.
Optimization method——Adjoint Approach
Advantages:
The optimization workload does not change with the number of design parameters, making the refined design of multistage compressor become a reality.
Aeroengine companies such as Rolls-Royce (R.R.) have used it as a major part of the design system.
