Gear type extension arm multi-level steam compressor

Abstract

The invention provides a gear type extension arm multi-level steam compressor. The gear type extension arm multi-level steam compressor comprises a spindle, impellers and a gear box. The spindle and a rotating shaft of the gear box are integrally formed and are arranged on the two sides of the gear box in a penetrating manner. The spindle is sleeved with the multiple impellers in a series connection manner. The impellers are distributed on the two sides of the gear box. Box bodies are arranged on the two sides of the gear box, and a first compression cavity and a second compression cavity are formed between the box bodies and the impellers and communicate with each other. The spindle is sleeved with the multiple impellers in the series connection manner, the impellers are distributed on the two sides of the gear box, the structure is compact, various connecting structures of a transmission part are omitted, and efficiency is improved; and the use temperature rise range is wide, the temperature rise adjusting manners are diverse and are not only limited in rotation speed adjusting, the different impellers can also be used for improving efficiency and temperature rise, and the relative standard degree is high.

Description

technical field [0001] The invention relates to the technical field of equipment manufacturing and processing, and more specifically relates to a gear type outrigger multistage water vapor compressor. Background technique [0002] Centrifugal compressor is a general-purpose machine that increases gas pressure and is used in many sectors of the national economy. As a new heat recycling device, the water vapor compressor increases the saturation temperature rise by increasing the pressure of low-pressure steam, and the temperature of the water vapor is stable, which can effectively improve the quality of the product, and use a very small amount of electric energy to make a large amount of low-pressure The internal energy of the steam can be reused, the efficiency is very high, the energy demand is reduced, and the circular economic operation of energy and materials is realized at the same time. The working condition of the water vapor compressor depends on the rotation of the...

Problems solved by technology

However, there are many working conditions with small flow rate and saturated temperature rise of 20°C to 30°C. The existing single-stage water vapor compressor can no longer achieve this kind of working condition, or the efficiency will be sacrificed by using Roots blower, and the reliability is not good. High and noisy, or to increase the speed, but the higher the speed, the higher the requirements for the equipment, which leads to the reliability and standardization of the water vapor compressor is not high, but the cost is increased a lot, which seriously restricts The Development of Water Vapor Compressor
