DG-II, III cascade pressure centrifugal fan
Patent No.:200420084329.2 200410070957.X 200520122521.0 200620113329.X 200610076680.
★ Product Overview
DG-Ⅱ, Ⅲ type cascade high-pressure centrifugal fan is DG-type low-noise high-pressure centrifugal fan base to build on a higher pressure low flow centrifugal fan. It can be widely used in chemical industry, environmental protection, pesticides, fertilizers, pharmaceuticals, paper, food, drying, gasification, gas turbine shaft seal ventilation, forced ventilation and high pressure pneumatic conveying device. It is small, light weight, low noise, high efficiency, has on many occasions to replace the imported fan.
★ basic structure
This product is mainly composed of the impeller, casing, inlet, bay, transmission (A type without) and motor components.
Impeller blades, front disc, rear disc and shaft disk (using imported quick quick release assembly, disassembly without Trueshot impeller deadlift) composition, according to the different requirements can be high-quality carbon steel or corrosion-resistant stainless steel, the strict dynamic balancing test, smooth operation.
Carrying case made of lightweight, high-strength structural negative pressure, the material can also be used to the different requirements of high quality carbon steel or corrosion-resistant stainless steel.
C-and D-type with a transmission mechanism, by the spindle, bearing housing, bearings, pulleys or couplings components.
Fan can be made to rotate the right and left to rotate in two forms, from the motor or bearing housing end of the face, the impeller rotates clockwise, called the right-hand fan, the "right" or "S" indicates, according to counter-clockwise rotation , called L-blower to "left" or "N" means.
Fan outlet position, exit angle to the cabinet, said adjustment range between 0o ~ 225o interval 45o, 90o sample is represented on the form, the use of units should have different requirements when ordering.
Rack uniform application of carbon steel plate and steel manufacturing.
Composition of each component assembly machine, each part can be individually removable, and will not cause a failure of a component machine scrapped.
Lower rack according to different machine equipped with the appropriate number of shock absorbers, having poured puzzle dedicated infrastructure, only to be solid flat.

Transmission
A formula - Direct drive motor, Ⅱ type from machine number № 4 ~ № 9.5.
Type C - belt wheel drive, all machine number.
D-type - coupling transmission, all machine number.
★ Installation Requirements
Foundation: thickness of not less than 300mm concrete floor surface basic level, according to the fan frame on each side plus put ≥ 200mm and above the surrounding floor 100mm.
Duct connection: import and export between the duct and fan expansion joints must be flexible coupling; import and export should be added the fan air flow control valve, the appropriate boot off small, in order to facilitate starting, at run-time by the need to control traffic. Extended range of applications
The technical performance parameters according to the medium is designed to determine the standard state of the air, it can also serve as the practical application of high-temperature corrosive gases and gas transport, this time the physical properties of the transmission medium should be converted into the standard state properties of the air again Selection When the parameters, structure have special requirements, the Company may be non-standard design alone.
