Description

Technical Field

[0001] The utility model relates to the field of high-speed air suspension blowers with dual-machine joint control, and more specifically, to a high-speed air suspension blower with dual-machine joint control. Background Art

[0002] The magnetic suspension blower is a new type of high-efficiency energy-saving and environmental protection product that applies active magnetic suspension bearing technology and high-speed permanent magnet synchronous motor technology on the basis of traditional blowers and is integrally designed. The main structure is that the blower impeller is directly installed on the extended end of the motor shaft, and the rotor is vertically suspended on the active magnetic bearing, realizing direct drive by a high-speed motor. Using a magnetic suspension motor to drive a compressor-expander unit can effectively improve the system performance;

[0003] The actual gas consumption requirements of different enterprises are different and vary greatly. At present, the flow output of a single blower is limited, and it is impossible to achieve a large-power flow output, which cannot meet the situation where the required gas consumption is large; in its existing technology patents, there are devices with parallel dual machines. For example, in the patent disclosed in the prior art, according to the authorization announcement number CN221373960U, the utility model relates to the technical field of blowers, and in particular to a dual-machine joint control magnetic suspension blower, including a blower body and an exhaust pipe; the blower body includes a housing and a volute. The volute includes a first volute fixed to the left end of the housing and a second volute fixed to the right end of the housing. An external interface is provided on the outer surface of the second volute; the exhaust pipe includes a first exhaust pipe, a second exhaust pipe, and a parallel exhaust pipe. The parallel exhaust pipe has three pipe orifices, and two of the pipe orifices are arranged on one side of the parallel exhaust pipe and are respectively connected to one end of the first exhaust pipe and one end of the second exhaust pipe;

[0004] Among them, there are two groups of blower bodies, namely a first main machine and a second main machine; among them, the external interface of the first main machine is fixedly connected to the other end of the first exhaust pipe, and the external interface of the second main machine is fixedly connected to the other end of the second exhaust pipe; by connecting two groups of blower bodies in parallel, it can have a larger flow output and increase the frequency modulation range of the blower; however, in the above-mentioned prior art patent, when in use, a guide air duct with a parallel structure needs to be installed, and the pipeline part is a fixed-structure pipeline. In actual use, the positions of the first machine and the second machine are not fixed, and their length spacings are different, and they cannot be adjusted during assembly at the pipeline, and the assembly is not flexible enough.
