[0032] Example
[0033] Such as Figure 1 ~ Figure 3 as well as Figure 5 As shown, a centrifugal compressor includes a volute 3 connected to an air inlet pipe 1 and an air outlet pipe 2, and also includes an impeller 10 and a motor 5. The impeller 10 is placed in the volute 3. According to the prior art, it is known : The motor 5 can be directly connected to the impeller 10, that is, the power output end of the motor 5 is connected to the impeller 10.
[0034] In order to improve the compression efficiency of the compressor, the following technical measures are taken: add a water spray pipe 9 with a spray head 901, which is arranged on the intake pipe 1, or the water spray pipe 9 is arranged on the volute 3 to spray water The nozzle 901 of the pipe 9 faces the inner cavity of the volute 3, that is, the nozzle 901 faces the impeller 10.
[0035] In this way, the water spray pipe 9 sprays water into the volute 3 through the spray head 901 to ensure that the compression process of the...
