Dalingshan ventilation ducts, 13592790213 Wai Hing ventilation equipment, pipeline

The main products are: air filter, the early effect filters, bag filters, HEPA filters, activated carbon filters, high temperature filters, air conditioning filters, dust filter, cartridge filter, complete sets of ventilation and filtration equipment , waste gas treatment equipment, environmental purification equipment and other centrifugal fan impeller and casing composed mainly of small fan impeller directly mounted on the motor, the large fan motor through the coupling or belt coupling. Usually unilateral centrifugal fan intake, with single-stage impeller; a large flow of intake air can be bilateral, with two back to back impellers, also known as double-suction centrifugal fan. Fan impeller is the main component, its geometric shape, size, number of leaves and manufacture of precision have a significant impact on performance. Impeller static balance or balancing correction to ensure smooth rotation of the fan. The export orientation of different blade impeller into forward, radial and backward three types. Front inclined toward the top of the impeller blades of the impeller rotation direction; the top of the blade radial impeller is in the radial direction, and parted straight blade and curved blade; after the reverse rotation of the impeller is inclined toward the top of impeller blades. The maximum pipeline pressure generated by the impeller before, in constant flow and number of revolutions, the minimum required impeller diameter, but the efficiency is generally lower; pressure after the impeller contrary, the resulting minimum required impeller diameter Huang Jiang maximum ventilation ducts, The efficiency is generally higher; radial impellers in between. Vane-type lines are straight blade simplest and most complex airfoil blades. In order to have the right blade surface velocity distribution, generally using curved blades, such as constant thickness arc blades. Impeller cover discs usually have to increase the strength of the impeller and reduce gas leakage between the blade and the casing. Coupled with the cover plate of the blade by welding or riveting. Lighter weight impeller welding, smooth flow. Low, medium small centrifugal fan impeller is also made of aluminum alloy casting. When Jiang axial fan ventilation duct work, power machine driven impeller rotating within a cylindrical enclosure Hengli exhaust pipes, gas enters from the collector to obtain energy through the impeller, increasing the pressure and speed, and then axially discharge. Axial fan arrangement of vertical, horizontal and inclined three, small, only about 100 mm impeller diameter, large up to 20 meters.
