  Under design conditions, fans with air pressure of 30KPa ~ 200KPa or compression ratio e = 1
3 ~ 3 belong to the category of high-pressure fans
At present, air ring vacuum pumps are generally classified as high-pressure fans in the industry
High pressure blower, also known as high-pressure blower, is different from general centrifugal blower? Fan Working principle , When the impeller rotates, due to the action of centrifugal force, the wind vane urges the gas to move forward and outward, forming a series of spiral movements
The air between the impeller blades accelerates the rotation in a spiral shape and squeezes the gas outside the pump body into the side groove (inhaled by the suction port)
When it enters the side channel, the gas is compressed, and then returns to the impeller blades to accelerate the rotation again
When the air passes through the impeller and side groove along a spiral track, each impeller blade increases the degree of compression and acceleration
With the progress of rotation, the kinetic energy of the gas increases, which further increases the gas pressure passing along the side channel
When the air reaches the connection point between the side slot and the discharge flange, the gas is squeezed out of the blade and discharged from the pump body through the outlet muffler Fan characteristics generally, the high-pressure fan has the following characteristics: 1
It has dual functions of blowing and suction
One machine can be used for both suction and blowing; 2
When running with little or no oil, the output air is clean; 3
Compared with centrifugal fan and medium pressure fan, its pressure is much higher, often more than ten times that of centrifugal fan; 4
If the pump body is die cast as a whole and the shockproof mounting foot seat is used, the requirements for the installation foundation are also very low
It can even operate normally without fixing the foot seat, which is very convenient and saves the installation cost and installation cycle; 5
Compared with similar fans, its operation noise is low, and the Ultra-static high-pressure fan is introduced: 6
Maintenance free use; Its loss parts are only two bearings, which basically do not need maintenance within the warranty period; 7
The mechanical wear of the high-pressure fan is very small, because there is no other mechanical contact part except the bearing, so the service life is of course very long
As long as it is under normal service conditions, there is no problem for 3 ~ 5 years
