Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0018] The working principle of the present invention is as follows: the output shaft of the power unit 5 is driven by an external energy source to generate rotational motion, drives the high-pressure fan 3 and the low-pressure fan 7 to operate, and outputs compressed gas and low-pressure gas at their respective air outlets.

[0019] Such as figure 1 The shown embodiment 1 of the dual-pressure fan is a dual-pressure fan, including a power unit 5 and a high-pressure...

Abstract

The invention relates to the technical field of a fan and particularly relates to a dual-pressure fan, comprising a power device, a high-pressure fan and a low-pressure fan, wherein driving forces of the high-pressure fan and the low-pressure fan are provided by the power device; the dual-pressure fan can respectively provide compressed gas and lower-pressure gas during operation. The power device is respectively in coaxial connection with the high-pressure fan and the low-pressure fan by the output shaft of the power device. The dual-pressure fan has the advantages of scientific and reasonable structural design and compact structure and can solve a problem that an existing fan cannot respectively provide compressed gas and low-pressure gas for gas equipment. By single power device, the output shaft of the power device conducts rotary motion under driving of external energy sources, thereby driving the high-pressure fan and the low-pressure fan; compressed gas and low-pressure gas at respective air outlet are respectively output; the dual-pressure fan has the characteristics of simple installation and control and the low purchasing and using cost.

Description

technical field [0001] The patent of the present invention relates to the field of fan technology, in particular to a dual-pressure fan. Background technique [0002] Fan is the customary abbreviation for gas compression and gas delivery machinery. It is a machine that converts mechanical energy into gas pressure and kinetic energy and transports the gas out. The design or selection of the fan is based on the pressure, flow and other demand technical indicators of the gas equipment. For different gas needs, different fans are usually designed or selected to meet them. [0003] In some application fields of gas equipment that require gases of different pressures, the design or selection of multiple fans may be limited by the installation location and volume of the fans and cannot meet the requirements. , increasing the procurement cost and the complexity of the control device. Chinese patent CN200620041692 discloses a dual-pressure dual-flow fan, which adopts the technical ...
