Middle-speed high-pressure multi-stage centrifugal blowing machine

Abstract

A medium speed high pressure blower of multistage centrifugal type is prepared as applying vertical split cylinder structure, setting multiple steel or aluminium impeller on master shaft, supporting master shaft by bearing box at one end of cylinder and body-connected gear box at another end of cylinder, using body-connected gear box as part of cylinder on blower for raising rotary speed of impeller to obtain higher pressure.

Description

technical field [0001] The invention relates to the field of mechanical blowers used in various industrial applications, in particular to a medium-speed and high-pressure multistage centrifugal blower. Background technique [0002] Centrifugal blowers are usually used in a variety of industrial applications. In blower language, relative to the traditional medium pressure (5-15 psi), the pressure of 15-25 (psi) is usually called for high pressure. Examples of the use of blowers with high pressure capability in industrial applications are: deep tank aeration tanks used in modern sewage treatment plants, supply of oxygenated air for various combustion processes, pressurization of various gases, and as vacuum power source. [0003] However, conventional direct-drive multi-stage centrifugal blowers are difficult to achieve pressures of 15-25 (psi). This is mainly due to the low impeller rotational speed, the number of stages being limited by the critical rotor speed, and high ...

AI Technical Summary

Problems solved by technology

[0019] Compared to the low speed DDMS 10, the high speed IGSS blower 30 has a high speed and blade load and therefore is much more noisy

Its high frequency noise makes it very annoying or potentially harmful to nearby operators

For such high noise, environmental regulations and standards often require the addition of soundproof cabinets to reduce the noise level, further increasing product costs and increasing the difficulty of machine maintenance
