Structural characteristics of multi-stage centrifugal blower

The multistage centrifugal blower is characterized by the structure of the main engine part, accessories and supporting parts, the accessories include elbows, mufflers, filters, total-purpose wire mesh filters, and special purpose (microporous aeration, etc.) low and mid-range filters. After understanding the structural characteristics, let's take a look at the starting sequence of the multistage centrifugal blower, first contact the display and the central control room, clean the drain pipe, pump, and then turn on the electric heater and check the parameters. The specific starting sequence of the multi-stage centrifugal blower.

1.What are the structural characteristics of a multistage centrifugal blower

Multi-stage centrifugal blowers are widely used in various smelting blast furnaces and iron-making furnaces, supporting coal washing jigs, mine flotation, sewage aeration, chemical gas and other places that require air for transportation, and can also be used to transport other special gases. This series of blowers has the characteristics of high efficiency, low noise, stable operation, no pulsation, wide stability zone, clean gas, dry, oil-free, less wearing parts, easy installation, operation and maintenance.

2. The multi-stage centrifugal blower is composed of three parts:

Main engine part: blower main engine, motor (general-purpose, outdoor type, explosion-proof type), main engine and motor coupling co-seated, main engine and motor direct coupling.

Accessories: elbows, mufflers, filters, wire mesh filters for general purposes, low- and medium-range filters for special purposes (microporous aeration, etc.).

Accessories: fan inlet disc valve (manual type, electric type), motor control start cabinet, flexible joint D series ,single suction and double support structure. Coupling transmission, from the motor side, the blower rotates in a clockwise direction, the fan has two types of high speed and low speed, the spindle adopts steel shaft design, non-contact zigzag seal, no wear and heat, excellent sealing performance, motor seat and shell separation.
