GM Series Gear-increased Centrifugal Blower

Description

GM series blower is a product we manufacture by introducing technologies from Kawasaki Heavy Industries Group (KHI). It is designed and calculated with our advanced optimized aerodynamic design program, applying a modular impeller meridian plane cutting technique and using efficient semi-closed and mixed-flow type 3D impellers. It is designed and manufactured on the basis of key innovative technologies including stability design software for rotor vibration with the finite element method, finite element analysis of impeller intensity, vibration design software, etc.,

as well as our decades of experience in the design and manufacturing of centrifugal blowers, featuring high efficiency, energy conservation, low noise, oil-free gas transfer, less floor space, long operating cycle, easy installation, maintain and use.

1、Explanations on GM model (e.g. GM*5)

G*-Initial of the English word GEAR-INCREASED
M*-Initial of the English word MIXED-FLOW TYPE
***-Equivalent diameter of the impeller (in cm)
GM *5L******-Lfor low pressure, andHfor high pressure

GM series air blower is of the structure of a single-stage hanging-arm, axial intake and radial exhaust. Air passes through the inlet duct with silencer and enters suction pipe and inlet vane guide. This is connected by the main driver by dint of the coupler and speed-increasing gear, which does work to the air by driving the 3D mixed-flow semi-closed impeller rotating at high speed. The air is exhausted through the diffuser, spiral housing and diffusing pipe. The fan lubricant is supplied by the main oil pump which is connected directly to the driving shaft, and by the electric auxiliary oil pump when starting and shutting down. The axial thrust of the high speed rotor is transferred from the thrust collar to the low speed shaft, greatly reducing the mechanical losses.
