8-09, 9-12 type high pressure fan

A high-pressure fan is a fan with a wind pressure of 30kPa~200KPa or a compression ratio e=1.3~3 under the design conditions. The current industry generally classifies gas ring vacuum pumps as high-pressure fans. High-pressure fans, also called high-pressure blowers, are different from general centrifugal blowers.
Under normal circumstances, high-pressure fans have the following characteristics:
1. It has dual functions of blowing and sucking, one machine can be used for two purposes, and it can be used for suction or blower;
2. Running with little or no oil, the output air is clean;
3. Compared with centrifugal fans and medium pressure fans, the pressure is much higher, often more than ten times that of centrifugal fans;
4. If the pump body is integrally die-casted and uses anti-vibration mounting feet, then it has very low requirements for the installation foundation, and it can even run normally without fixing the feet, which is very convenient and saves installation costs. And installation cycle;
5. Compared with similar fans, its running noise is lower, and the ultra-quiet high-pressure fan is introduced:
6. Maintenance-free use; its wear parts are only two bearings, and basically do not need maintenance within the warranty period;
7. The mechanical wear of the high-pressure fan is very small, because there are no other mechanical contact parts except the bearing, so of course the service life is also very long. As long as it is under normal use conditions, 3 to 5 years will be no problem at all. of;
