Now all kinds of equipment cannot leave the radiator cooling fan, cooling fan, of course, the type is also there are many kinds of, today we are possessing - radiator cooling fan manufacturer Chi automotive air conditioning technician for everyone to explain the main dc blower and the characteristics of axial flow fan and the difference. First: install difficulty degree of different dc blower general device in air conditioning unit inlet and outlet, induced draft fan for boiler drum, and so on location, device is more complex; Axial flow fan is a device in air duct prone, or duct exit front end. Second: the structure of different 1, general by dc blower impeller, casing, current collector, motor and transmission parts ( As the main shaft, pulley, bearings, triangle, etc. ) Composition. Impeller by roulette, blades, wheel cap, shaft disk. Chassis consists of cochlear plate, side panel and leg. Fan blade forward or backward of blades, can be used for request of wind pressure air volume used more widely. And can do contained in the noise elimination, has obvious advantages in noise index. Motor and fan is generally through shaft connection. 2, general by axial flow fan impeller, casing, current collector, and the motor, impeller composed of blade and hub, chassis consists of ram, frame plate and the support. Axial flow fan blades confined to the diameter of the shell, motor generally within the fan. Third: different 1, air volume and air pressure blower with high pressure coefficient, the relatively low flow coefficient, according to the high and low pressure can be divided into high pressure ( 15000~3000Pa) , medium voltage ( 3000 ~ 1000 pa) And low pressure ( < 1000 pa) 。 2, axial flow fan with low pressure flow characteristics of the high and low pressure are divided into high pressure ( 500~5000Pa) And low pressure ( < 500 pa) 。 Low pressure ventilation is used mainly for general use. Fourth: principle of different 1, blower principle: axial airflow into the rotating blades, under the action of centrifugal force was thrown to the impeller outer edge and the outlet. 2, axial flow fan principle: gas axial into rotary vane axial discharge from the other side again after be pressurized. Above is the dc fan peng and the characteristics of axial flow fan and difference. We wen ling chi car air conditioning cooling fan factory is specializing in the production of radiator cooling fan, dc cooling fan, fan, dc peng turbo cooling fan, domestic famous brand, excellent quality, good service, reasonable price.
