Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
The problems such as this utility model is low for existing vacuum pump efficiency, noise is big, service life is short, it is provided that a kind of oil-free
Vacuum pump.
As shown in Figure 1 and Figure 2, embodiment of the present utility model provides a kind of oilless vacuum pump, including vacuum pump 1, motor 2,
Acoustic filter 3 and vacuum tank 4, the described preferred DC brushless motor of motor 2.
Described vacuum pump 1 includes pump seat 100, graphite rotator 101, resin blade 102, the pump housing 103 and pump cover 104, described
Graphite rotator 101 is located in the space surrounded by pump seat 100, the pump housing 103 and pump cover 104, on described graphite rotator 101 circumferentially
Being evenly equipped with 4 radial slots, be embedded with a resin blade 102 in each described radial slot, the lower end of described graphite rotator 101 passes
Being connected with motor 2 by band device 5 of passing on Gong after pump seat 100, the described pump housing 103 is provided with vacuum noz(zle) 105.
Described acoustic filter 3 includes Sound damping cover 300 and covers at the sound proof housing 301 outside vacuum pump 1, described Sound damping cover 300
