Europe Three Lobes Vacuum Roots Blower
Model : EVV Series
Based on the RSS series, EV series was created, and then appeared in front of the public in the form of vacuum. With the latest CNC processing technology in the world, we manufacture accurate impellers. It is assembled and tested by technicians with many years of experience to produce EVV series with high performance, low noise and low vibration.
Bore : 1.5” ~ 16” (EVV40 ~ 400)
Capacity : 0.5 ~ 360 ㎥/min
Pressure : -6,000 ~ 0 mmAq.
Features:
- High speed, High flow
- High efficiency, High pressure, High vacuum.
- Capacity is stable and the pressure changes are small.
- Eco-friendly. Don’t need to lubricate, without oil and gas.
- Precise and strong structure.Light weight. Long time operation. Long life
- High mechanical efficiency and Easy operation.
Three-Lobes impeller rotation:
The precision and accurate rotor is manufactured. The area utilization coefficient is 0.53, the volume efficiency is increased by 5%~8% at 98kPa, and the noise is reduced by about 5dB.
CNC machining technology:
All the rotors are produced by special precision CNC equipment, and the quality is checked by professional technicians, so there is no performance error between each blower. The rotor has been subjected to dynamic and static balance tests before assembly, so the vibration of the blower is minimal.
- High efficiency. High speed, Energy saving: European models are more efficient and energy efficient.
- Lower energy consumption: The three-lobes design reduces countercurrent pressure on the rotor, and correspondingly reduces energy consumption.
- Bearing life extension: The design of the three-lobes blower is derived from HEY-WEL to optimize the load distribution between the rotor and the gear. By the proper balance of the three impellers, the blower can provide a higher speed, and effectively reduce the vibration in the operation process and increase the resistance of deflection, so that the service life of the bearing is increased by about 20%.
- Effective noise reduction: The design of the three-lobes blower can control the backflow pressure of the rotor by the impeller, which can effectively reduce the pressure pulsation in the process. This not only saves energy consumption, but also reduces noise by about 10dB.
- High efficiency and easy maintenance: Three-lobes blowers are lubricated by oil, and the bearings can provide the advantages of lower operating temperature and longer running time, so as to improve production efficiency. At the same time, the dual tank design is separated from the gas chamber, which will allow it to discharge pure gas and easy maintenance. Maintenance is cheap and maintenance cycle is long.
- New system: The new type of fully enclosed oil tank and lubrication system ensure that the blower does not spray oil and oil leak, and put an end to the old Roots blower oil injection, oil leakage phenomenon caused by the site pollution.
- High quality: The machines produced by Hey-Wel are all subjected to strict test and quality inspection before shipment.
