Example Embodiment

[0013] Figure 5 It is an example of a two-stage vortex pump with a single impeller. When the impeller is driven to rotate by the prime mover, the conveyed fluid is driven by the working surface (8) behind the rotating impeller, figure 2 The air inlet (6) shown enters the rear flow channel (3) for the first pressurization, and the fluid flow generated by the rotation of the impeller presses Figure 5 Enter the bottom channel (10) in the direction indicated by the solid line with arrows, and enter the front flow channel (1) through the bottom channel (10), and then perform the second time under the rotation of the front working surface (9) of the impeller Pressurized and after figure 2 The air outlet shown flows out, thereby realizing the function of series boosting. Compared with the two-stage vortex pump of the prior art, the two parts of an impeller and a partition are reduced, the volume is reduced by 15%, and the cost is reduced by 18%, achieving the purpose of improvem...

Abstract

A single impeller two-stage vortex air pump uses one impeller to realize the function of the two-stage vortex pump. The front and rear working surfaces of a single impeller are used as two unit stages of the vortex air pump, the rear working surface (8) and the rear flow channel (3) of the impeller (5) form the first stage of the vortex air pump, and the impeller (5) The front working surface (9) and the front flow channel (1) form the second stage of the vortex air pump; the first stage and the second stage are connected through the bottom channel (10), and the bottom channel is placed at the air inlet and outlet of the air pump. Between the tuyeres, the function of the series supercharging of the two-stage vortex pump is realized by the bottom channel; an isolation belt (11) is arranged on the middle of the outer circle of the impeller (5), and the isolation belt (11) separates the front working surface of the impeller (5) ( 9) Realize isolation of high and low pressure areas from the rear working face (8). Compared with the two-stage vortex air pump of the prior art, the two-stage vortex air pump of the present invention has one less impeller and one separator in structure, reduces the number of matching parts, reduces the cumulative error generated during assembly, and makes the processing convenient and efficient. The assembly is simple, and at the same time, the volume is reduced and the cost is reduced.

Description

technical field [0001] The invention relates to a two-stage vortex air pump, more precisely, a two-stage vortex air pump which uses only one impeller to realize the functions of two unit stages. Background technique [0002] A vortex air pump is an air pump used to generate high-pressure airflow. In products of the prior art, the structure in which an impeller is located is usually regarded as a unit stage for generating pressure. In order to obtain higher pressure, in addition to increasing the impeller diameter of the vortex air pump, another common method is to use two unit-level vortex air pumps in series, that is, the outlet of the first unit stage is connected to the second unit by a channel On the inlet of the first stage, this two-stage serial use function is called series supercharging, and the vortex air pump that realizes series supercharging in the same machine is called a two-stage vortex air pump. Application number is: CN201220364641.1, publication number: C...
