DG-ZZ special high voltage paper centrifugal fan

Patent No.:200420084329.2 200410070957.X 200520122521.0 200620113329.X 200610076680.0


★ Product Overview

DG-ZZ paper dedicated to the special high-pressure centrifugal fan forced air papermaking process, according to the different working conditions, the series is set up flow, total pressure to match the seven specifications, process adaptability and energy-saving effect is remarkable in this series high pressure centrifugal blower fan for the DG derived products, impeller blades backward arc, noise is significantly lower than the domestic high-pressure fan.

Fans of the series of conventional products of high quality stainless steel body, can also be based on user requirements using carbon steel.

★ basic structure

This product is mainly composed of the impeller, casing, inlet, racks and electrical components, D series is also equipped with drive mechanism.

Impeller blades, front disc, rear disc and shaft plate composed of conventional products made of stainless steel or high carbon steel, the strict dynamic balancing test, smooth operation.

Negative carrying case made of high-strength structure, using high-quality stainless steel or high carbon steel.

Rack uniform application of carbon steel plate and steel manufacturing.

Fan can be made to rotate the right and left to rotate in two forms, from the motor side face, the impeller rotates clockwise, called the right-hand fan, the "right" or "S" indicates, counterclockwise 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.

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 dedicated puzzle fans poured foundation, subject to a solid flat.

★ Type Description

Model implications (for example) DG-ZZ (25-55)-A

                
A: A type transmission

55: 55x10 Pa total pressure

25: Flow 25x10m / h

ZZ: papermaking

DG: low-noise high-pressure

★ Transmission

   
A Series - Direct Drive Motor

 
D Series - coupling drive

★ Installation Requirements

Foundation: thickness not less than 300mm concrete floor (or steel), the surface of the basic level, according to the fan frame on each side plus not less than 200mm, and above the surrounding floor 100mm.

Duct connection: import and export between the duct and fan flexible expansion joints must be connected, otherwise it will cause vibration transmission; import and export should be added the fan air flow control valve, the appropriate boot off small, in order to facilitate starting at runtime by the need to control traffic.

The technical performance parameters according to the medium is designed to determine the standard state of the air, such as the media and the practical application of standard state is large difference in the air, the physical properties of the transmission medium should be converted into the standard state properties of re-selection of the air when parameters, structure have special requirements, the Company may be non-standard design alone.
