Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
Visible as shown in Figure 1, Figure 2, the four star-like air compressor without lubricants of the present embodiment, comprise head 1, motor 2, public underframe 3, base 4, the square case 40 that mates with base 4, described public underframe 3 is arranged on base 4, and both are welded as a whole; Head 1 is fixed on public underframe 3, and described motor 2 is arranged on the base 4 below public underframe 3; Described head 1 is provided with three cover one-level cylinder 6 and a set of secondary cylinders 7, described head 1 is also provided with crankcase 25, bent axle 11 is provided with in described crankcase 25, the power intake of bent axle 11 is provided with main frame belt pulley 19, described bent axle 11 turns structure for single, is provided with four connecting rods 12 be connected with three pistons overlapping one-level cylinder 6 and a set of secondary cylinder 7 respectively; Three described cover one-level cylinders 6 and a set of secondary cylinder 7 at right angles distribution in a week, cylinder-bore axis and horizontal line setting at 45 °; Main shaft and the main frame belt pulley 19 of described motor 2 are in transmission connection; Three described cover one-level cylinders 6 are connected with secondary cylinder 7 respectively by pipeline; Described secondary cylinder 7 is connected with gas product output unit pipeline.
The present embodiment installation step: bent axle 11 utilizes ball bearing 13 to adopt be fixed on crankcase 25 at 2, on bent axle 11 in four connecting rods 12, first connnecting rod big end ball bearing puts in from snakelike bent axle power intake, be pressed into by oil hydraulic press successively, again two main bearings are pressed into place, for considering crankcase 25 inner space size and structural requirement of strength and producing the Economy of cost of material in enormous quantities, have two to adopt subdivision structure in four connecting rods 12 of this example, two monolithic linkage 12 should first be pressed on bent axle 11 with connnecting rod big end ball bearing.At this moment be tucked in crankcase 25 by the crankshaft group assembled by crankcase macropore, carry out bent axle two main shaft socket end positioning and fastening by bearing support, two subdivision connnecting rod big ends are then implemented to tighten up in crankcase.Also appropriate gap need be stayed in bent axle one end, because of the generation axial elongation that is heated during to make normally to turn round work during practical set.
As seen from Figure 1, the circuit design of this example is very characteristic, and four cylinders are imported and exported and all followed a principle---from down to up.The one-level row knock out drum 8 be placed in above crankcase 25 is also comparatively near with the mouth of pipe be connected, and follows saving, optimization, principle attractive in appearance.Because of the restriction of view breadth, the copper tube 10 of this example only illustrates with thin dashed line roughly to be moved towards.
This head 1 there are three covers identical one-level cylinder 6 and piston element and a set of secondary cylinder 7 and piston element.Secondary cylinder 7 is placed in illustrated third quadrant, convenient for pipe arrangement and that the one-level amount of draining is large surge volume needs, one-level row surge volume tank 8 is provided with on crankcase 25, one-level cylinder 6 is provided with air strain and sliencer 14, first air enters one-level cylinder cap 15 by air strain and sliencer 14, discharge through one stage of compression, three tunnels converge to one-level row surge volume tank 8 separately, then go out from one-level row surge volume tank 8 and enter the aluminium sheet cooler 9 being placed in chamber door side and cool.Secondary cylinder 7 is provided with secondary cylinder cap 16, cooled gas enters neighbouring secondary cylinder cap 16 suction port again, after secondary cylinder 7 compresses, enter secondary row knock out drum 18 through one-way valve 17.
Visible as shown in Figure 1, Figure 2, in the present invention, one-level cylinder 6 and one-level arrange surge volume tank 8, one-level is arranged the conduit connection such as surge volume tank 8 and aluminium sheet cooler 9 and divided, and all adopt copper tube 10 to connect.
A complete set of unit is placed in inside square case 40, square case 40 1 side is provided with axial-flow blower 21, and to cool cylinder and to accelerate casing inner air convection, axial-flow blower 21 is air draught types, outer for case ozone sucks by it, directly blows head with larger blast; A square opening is opened in position on the lower side, another side, motor pulley 20 is had near it, install the fan 22 of plastic material at its end face, and aluminium sheet cooler 9 is contained in the front of this fan, when machine runs, heat in aluminium sheet cooler 9 blows out outside square case 40 by this fan 22.Each link of a complete set of unit have followed the second law of thermodynamics.Due to the introducing of axial-flow blower 21, it can allow the gas of gas cooling higher temperature of higher temperature, so just obtains squelch type air compressor engineering feasibility.
As shown in Figure 4, in the one-level cylinder 6 of the machine, secondary cylinder 7, all use the piston ring 23 of filled polytetrafluoroethylene material to carry out the Oilless Lubrication Seal in Petroleum Gas of cylinder and piston, realize oil-free compression.A complete set of machine adopts star triangle start, and axial-flow blower 21 runs not by the impact of amount regulating system.Just run continuously after air compressor connects with the mains starting up, until shut down, piston ring 23 operational failure when can effectively avoid temperature higher like this.
The main shaft of described motor 2 is provided with motor pulley 20, and described main frame belt pulley 19, motor pulley 20, in distributing up and down, are provided with belt 5 between the two.
As shown in Figure 3, described base 4 is provided with multiple long waist shaped hole 30, described motor 2 is fixed on base 4 by long waist shaped hole 30.Long waist shaped hole makes motor position adjustable, has adjustment surplus when being beneficial to belt pine.
Described square case 40 is provided with the silencer 24 of sound-absorbing sponge material, noise can be reduced further.
As shown in Figure 5, the base 4 of the machine mates with square case 40, and a complete set of unit is placed in inside square case 40, effectively can reduce ambient noise.
Adopt the technological scheme of patent of the present invention, overall structure exquisiteness is careful, heat, the high and low noise of dynamic efficiency, ultralow vibration.Be specially adapted to the air compressor without lubricant that discharge capacity is 3 ~ 4 cubic meters per minute.
