Improved type axial-flow compressor

Abstract

An improved axial flow compressor, including a machine body, air inlets and air outlets are respectively arranged at both ends of the machine body, a rotating shaft is arranged in the center of the body, a runner is fixed on the rotating shaft, and when the runner rotates, a Blades forming axial air flow, air flow passages are formed between adjacent blades, the blades are two groups of front and rear groups surrounding the circumferential surface of the runner, and the inner wall of the body between the two front and rear blades is provided with a direction opposite to the direction of the blades. The deflector is provided with a water cooling chamber for reducing the airflow temperature on the deflector fixed ring seat arranged between the two front and rear blades. The effect of the present invention is: changing the cold water pipeline into an annular water cooling chamber, reducing the space occupied by the original cold water pipeline, making the body structure of the axial flow compressor more concise and compact, and reducing the difficulty and cost of operation and maintenance. The airflow cooling space is effectively reduced, the contact surface between the airflow and the water cooling chamber is increased, the cooling effect of the airflow is improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to an improved axial flow compressor. Background technique [0002] An air compressor is a general-purpose device that produces high-pressure gas and has a wide range of applications. Among the existing air compressors, there are generally two types of reciprocating (piston type) and screw type air compressors, and other types are smaller. Both reciprocating and screw air compressors are volumetric principle structures, both of which have friction and are inseparable from the lubrication of oil. Therefore, the ensuing failure rate is high, energy consumption is large, the volume is large, the cost is high, and the discharge The gas contains oil. For some users who have special requirements to discharge gas without oil, they can only consider choosing centrifugal air compressors, but centrifugal compressors are expensive, and the quality of domestic centrifugal air c...

Problems solved by technology

[0004] 1. Because the cold water pipeline needs to occupy a specific space in the body, the axial flow compressor of the same model and power cannot be miniaturized;

[0005] 2. The cold water pipeline needs to be made separately, and then installed in the axial flow compressor, which increases the production cost and repair difficulty of the axial flow compressor;
