The utility model has the advantage of: 1. owing to adopt L₂The sleeping cylinder of-17/3-I air compressor machine and L₂The vertical cylinder of 10/8-I air compressor machine, thus cylinder diameter is changed, row pressure is low, and capacity is increased to 22m³/ min; 2. former type all adopts one-way air inlet, Improved type adopts bidirection air intake, gives simultaneously vertical cylinder and sleeping cylinder branch by two easing valves Other air inlet has reduced intake resistance, lives owing to vertical, cylinder all adopt cast iron simultaneously Plug though rotator inertia increases, reaches comparatively ideal dynamic balancing, so when running well Obvious energy conservation. Experiment shows former L₂-17/3-I type air compressor machine need adopt 65KW Motor, and energy consumption of the present utility model only has 55KW. 3. former L₂-17/3-I The type air compressor machine is because fault of construction can't adopt foundation-free base, this improvement in the use Type makes its center of gravity substantially placed in the middle owing to adopt cast-iron piston and bidirectional air intake structure, Adopt the foundation-free base, need not the cement casting base, conveniently moving, and vibrate little, It is very steady to turn round.

Embodiment: this specification the 5th part and accompanying drawing 1-6 be clear to have described an embodiment of the present utility model.Here no longer repeat.Be noted that intake and exhaust bellows 1 are weldment, and change filler 9 into PTFE by original steel filler, the surface friction drag during with the attenuating piston rod movement.

Working principle of the present utility model is: by the driven by motor crankshaft rotating, crosshead moves and makes reciprocating motion of the pistons.Gas is entered in the cylinder flap by the both sides easing valve respectively, enters upright, the cylinder that crouches by suction valve, is discharged by outlet valve after Piston Compression, enters in the bellows, enters in the gas holder for using again.The oil lubrication of the same bent axle of connecting rod, crosshead is to rotate by bent axle to drive the oil pump rotation, lubricant oil in the fuselage oil sump is pumped into the bent axle endoporus, give the connecting bar and crankshaft connection place lubricated on the one hand, on the other hand, give crosshead lubricated with connecting rod junction and cross slideway, the oil gun of oil pump drive simultaneously is lubricated for the inboard wall of cylinder block fuel feeding.
