Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] See attached Figure 1-3 : The impeller structure for a compressor or blower includes a shaft 1, a first diameter section 11, a second diameter section 12, a blade 2, a leading edge 21, a trailing edge 22, a front disc 3, a toothed seal 31, and a rear disc 4 , Rear disk sealing ring 41, tooth seal 42, bypass channel 43, wheel hub 5, arc section 51, arc nut 6, threaded connector 7.

[0020] The rotor includes a rotating shaft 1 and an impeller. The rotating shaft 1 sequentially includes a first diameter section 11 and a second diameter section 12 whose diameters are successively reduced; The outer circumference of the threaded connector 7 has an external thread, one end of the threaded connector 7 is screwed with the second diameter section 12, and this end is screwed into the internal thread hole of the second diameter section 12, and the other end of ...

Abstract

An impeller structure used for a compressor or an air blower comprises a rotary shaft (1) and an impeller. The rotary shaft comprises a first diameter section (11) and a second diameter section (12),and the impeller is installed on the rotary shaft through a threaded connection part and an arc nut. The impeller structure used for the compressor or the air blower is characterized in that a bypasschannel (43) is arranged on the inner side of a rear disk (4) and is an annular groove, the depth of the bypass channel (43) is e1, and the bypass channel is located on the outer side of the radial direction of a hub. The impeller structure increases the flow in front of an impeller outlet, improves the cavitation resistance of the impeller, reduces the probability of surging, and increases the sealing performance of the impeller outlet.

Description

technical field [0001] The invention relates to the field of fluid machinery, in particular to an impeller structure for a compressor or a blower. Background technique [0002] A compressor or blower is a fluid mechanical device that converts mechanical energy into fluid energy with gas as the working medium. The impeller structure plays a vital role in the efficiency and performance of the entire device. However, there is still a lot of room for improvement in the existing products to improve product performance. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a kind of impeller structure for compressor or blower, the impeller structure for compressor or blower increases the flow before the outlet of the impeller, and improves the resistance of the impeller. The cavitation performance reduces the probability of surge and increases the sealing performance at the outlet of the impeller. ...
