Characteristics of high pressure fan
Under normal circumstances, the high-pressure fan has the following characteristics:
1, with the dual function of blowing and suction, a machine dual-use, you can use suction, you can also use hair dryer;
2, less oil or oil free operation, the output of the air is clean;
3, relative to the centrifugal fan and medium pressure fan, the pressure is high, often more than 10 times more than the centrifugal fan;
4, if the pump body is integrally cast, and the use of the earthquake to install the feet, then it is the basis of the requirements of the installation is very low, even without a fixed foot seat can be a normal operation, very convenient, also very save installation cost and the installation period;
5, relatively the same fan, its operation low noise, ultra quiet high pressure fan:
6, maintenance free use; its loss is only two bearings, in the warranty period, basically do not need maintenance;
7, high pressure blower mechanical wear is very small, because in addition to the bearing, no mechanical contact, so the other life, of course is very long, as long as it is in normal use conditions, 3 to 5 years is no problem;
Application of high pressure centrifugal fan
Generally used for spraying, electroplating, radio, batteries, glass manufacturing industries, such as high pressure forced ventilation, can also be widely used for conveying materials, conveying gas.
Application conditions of high pressure centrifugal fan
1, the transmission of the media requirements: the delivery of the media should be non corrosive, non flammable and explosive, does not contain viscous substances, medium containing dust and hard particles is not greater than 150mg/m3.
2, medium temperature: generally can not afford to have 50 degrees Celsius (up to no more than 80 degrees Celsius)
Centrifugal fan structure
1, the centrifugal fan is a single suction type, the use of pre bent impeller.
2, according to the different direction of rotation of the impeller, the fan can be made into right and left rotation of the two. From one end of the motor face, clockwise rotation of the impeller for the right cyclone, to "right" means; counterclockwise rotation to the left cyclone, to "left".
3, centrifugal fan outlet angle can be made into 0 degrees, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees a total of 6 angles. My standard product is 0 degrees, 45 degrees, 90 degrees three, the rest of the angle can be produced according to user needs.
4, centrifugal fan transmission mode for A/D two:
A type: motor direct drive, compact structure, simple maintenance. Machine number 3.5~6.3# uses this kind of transmission way
D type: coupling, structure form an integral type: fan, drive motor group and all the assembly in the same rigid base, thereby reducing the customer installation difficulty, greatly shorten the installation and commissioning period. 7.1# and above the machine number using this kind of transmission.
