500 m³/min High-quality Advanced Centrifugal Vacuum Pump Equipment
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.
The advantages of centrifugal vacuum pump compared with water ring pump
| Item | Disadvantage of Water ring pump | Advantage of Centrifugal vacuum pump |
| Endurability& Maintenance Cost | There is cavitation problem in the blade as the blade is always in direct contact with white water, 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 | High-tech product with aviation-grade material and great operational reliability, average service life can be 10-20 years. |
| Performance | The performance of water ring vacuum pump decreases with the service life increasing. The impeller wear increases leakage, decreases vacuum and reduces efficiency. | 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. |
| Applicable Situation | Low flow rate, high vacuum degree(above -70kPa) | High flow rate,stable vacuum degree(-30 ~ -75kPa) |

Commissioning & Testing
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.
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.
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.
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.
