Further, the outlet side of the air compressor machine, the both ends of the valve, first coil pipe inlet end, described
The outlet side of filter core, the pressure meter switch both ends and corresponding pipeline between pass through quick coupling connect.
Further, it is provided on the pipeline that the gas outlet of the filter core is connect with the inlet end of main shaft positive seal structure
The controller of pressure meter switch, the pressure meter switch and carving machine electricly connects, when circuit air pressure is lower than critical value
When, controller cuts off carving machine working power.
The air supply system of the utility model, since the first coil pipe is spiral shape and is filled with sieve, air passes through from top to bottom
When crossing the first coil pipe, on the one hand realize on the other hand the separation of part oil, water in air passes through sieve under the action of the centrifugal force
Effect realizes that oil, water are collected as big drop by droplet, further realizes the separation of oil, water in air；Air passes through the second disk
It manages the oil that on the one hand can be avoided big drop to be arranged from bottom to top, water and filter core is brought by air, on the other hand, oily in air,
The enough further separation for realizing oil, water in air under the action of self-weight of water energy；It is equipped in filter core spaced from top to bottom
Filled by filtration layer, the filled by filtration slot is obliquely installed and the inclined direction of adjacent head filling slot is reversed, Neng Gouyou
Effect improves oil, water separating effect；And then pass through the optimal setting of the grease filter mechanism, clean air can be obtained, substantially
Main shaft is avoided to pollute because of positive seal structure.
