Abstract

The invention provides a forward multi-wing riveting double-impeller centrifugal ventilator for a CRH train converter. The forward multi-wing riveting double-impeller centrifugal ventilator for the CRH train converter comprises a left volute, a left impeller, air inlets, a three-phase asynchronous motor, a right volute, a right impeller, a mounting frame and connecting angle aluminum; the left volute and the right volute are connected with the mounting frame by bolts through mounting holes at the bottoms, and are fixed through the connecting angle aluminum; the left impeller and the right impeller are fixed in the left and right volutes through shaft extenders on two sides of a motor; and the air inlets are fixed on the outer sides of the left volute and the right volute through mounting set blocks on first side plates. Through improvement of the forward multi-wing riveting double-impeller centrifugal ventilator for the CRH train converter, the advantages of high efficiency, low noise,simple and compact structure, less space, high reliability and convenience to install in the CRH train converter are achieved, and the problems and the defects in the background technology are effectively solved.

Description

technical field [0001] The invention relates to the technical field of fluid machinery, and more specifically relates to a small-space, low-noise, low-vibration, high-safety reliability and high-efficiency forward multi-blade riveted double-impeller centrifugal fan for converters of EMUs. Background technique [0002] With the rapid development of China's high-speed EMU technology in recent years, higher requirements have been put forward for the various parts of the converter, which is one of the core components of the EMU; the fan, as the core component of the converter's heat dissipation, has gradually required Efficiency improvement, shock absorption, low noise and light weight; at the same time, higher requirements are placed on the reliability of fans. Among all reliability indicators, safety and reliability are undoubtedly the most important. In the existing technology A forward multi-blade riveted double-impeller centrifugal fan for EMU converters. Starting from the ...
