It is direct-connected with the crankcase on air compressor machine, the process of oil return is realized in a manner of mechanical structure, keeps oil return more stable, due to this time
Oily device is equivalent to the load for increasing motor on air compressor machine indirectly, so in large-scale high-power belt driven type piston pneumatics
Using effect is more preferable in machine.
In the oil return apparatus in above-mentioned belt driven type Piston Air Compressor, it is provided on the cabinet and connects with air compressor machine
The Integral flange disk connect, the end part seal of cabinet are provided with end cap.
In the oil return apparatus in above-mentioned belt driven type Piston Air Compressor, oil fill plug is provided at the top of the cabinet
And bleed screw, the bottom of the cabinet are provided with bottom plate.
In the oil return apparatus in above-mentioned belt driven type Piston Air Compressor, the upper cover of piston rod is lived equipped with several circles
Plug ring.
Compared with prior art, this oil return apparatus realizes oil suction and fuel-displaced effect, and and pneumatics by the sliding of ball
The direct-connected progress power input of machine upper crankcase, has the advantages that oil return effect is more stable.
