For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, mode of execution of the present utility model is described in further detail.
As shown in FIG. 1 to 3, in this embodiment, a kind of interior cooling unit without oily piston type air compressor, includes bent axle 10, crankcase 20 and fan 30.
Bent axle 10 and fan 30 are arranged at the inside of crankcase 20, bent axle 10 includes the rear shaft neck 11 be connected with belt pulley, rear shaft neck 11 is connected with crank 12, crank 12 is connected with rod journal 13, rod journal 13 is connected with front axle journal 14, front axle journal 14 is coaxial with rear shaft neck 11, front axle journal 14 with rear shaft neck 11 are respectively arranged with bearing, when rear shaft neck 11 rotates under belt pulley drives, can coaxial rotating, rod journal 13 is provided with connecting rod 40, connecting rod 40 is connected with piston, compresses air; And the rear shaft neck 11 of fan 30 and bent axle 10 and front axle journal 14 are connected.
In another embodiment, fan 30 divides into covering of the fan 31 and blade 32, and blade 32 is arranged perpendicular to covering of the fan 31.Have at least the rear shaft neck 11 of a fan 30 and bent axle 10 and front axle journal 14 to be connected, in this embodiment, have two fans 30 to be connected and fixed with front axle journal 14 and rear shaft neck 11 respectively.The blade 32 sections transverse bending of fan 30, the angle of its blade 32 can adjust, and to reach the direction controlling wind, thus cools the part of specifying, the air of bottom can be directed into top in a large number.
Bent axle 10 puts into crankcase 20 after being connected with fan 30, and crankcase 20, without seal request, offers intake grill 21 in the bottom of crankcase 20, and by padded for whole crankcase 20, the top of crankcase 20 is also provided with an exhaust outlet 22.Thus, during operation, gas goes out above entering from below, and one does not affect outward appearance, its two from security standpoint consider, prevent foreign material from entering crankcase 20.Certainly, if intake grill 21, exhaust outlet 22 are arranged on the face, left and right of crankcase 20 or front-back can, just on the one hand have impact on outward appearance, opening is located at other face dust etc. may be made to enter wherein on the other hand, also there is staff and stretches into risk inside crankcase 20 by mistake.
In this embodiment, bent axle 10 is provided with fan 30, and on crankcase 20, has intake grill 21 and exhaust outlet 22.The purpose of this utility model reduces the temperature in crankcase 20, and hot air from intake grill 21 inspiration crankcase 20, is then discharged from exhaust outlet 22 by fan 30 by cool exterior air.Intake grill 21 is arranged on bottom crankcase 20, and intake grill 21 is an enough large opening, and exhaust outlet 22 is the gap between cylinder 50 and crankcase 20, in practice is produced, uses padded screw or directly opening is all right.Crank 12 arranges the boss that extends to contact fan 30 surface, then with screw, fan 30 is fixed on boss.Intake grill 21 is arranged on the bottom of crankcase 20, opens an enough large hole; Exhaust outlet 22 is arranged at the joint of cylinder 50 and crankcase 20, and increase a pad it is padded, the gap then between cylinder 50 and crankcase 20 is as exhaust outlet 22.It is enough large that intake grill 21 needs to open, and outside can be made to have enough cool airs to come in, and in another embodiment, exhaust outlet 22, without the need to opening separately more above, uses the gap between cylinder 50 and crankcase 20 just enough.
In this embodiment, improve the degree of finish of cylinder 50 inwall, cancel and have the reticulate pattern adopted during oil to arrange, can friction be reduced, reduce to consume, indirectly reduce temperature.Bent axle 10 is provided with fan, fan 30 is fixedly connected on crank 12, connecting rod 40 connects piston, outside piston, cover has support ring, support ring contact cylinder 50 inwall, and upper piston area is provided with seal ring, support ring and seal ring are referred to as piston ring, support ring and seal ring variable thickness sample, seal ring is thicker, prevents gas leakage.
After adopting interior cooling unit of the present utility model, can effectively reduce the temperature of air compressor inside, after temperature reduces, just can use the lubricant oil of domestic general hundreds of yuan per kilogram, cost reduces greatly; Whole component do not need to work at high operating temperatures simultaneously, all greatly decline to the requirement of its material and processing request; When air compressor inside does not produce high temperature, its energy consumption reduces, and does not need to cool air, and is working without under oil condition, and whole pressurized air is all very clean, does not need the equipment such as deaerator.
Under the state not having high temperature, the consume of equipment reduces greatly, extends the working life of equipment.
Meanwhile, former air compressor necessarily requires sealing, prevents leakage of oil, and the utility model initiatively offers intake grill 21, exhaust outlet 22 on crankcase 20, reduces crankcase 20 processing request.
As can be seen here, the utility model effectively reduces operating temperature without oily piston type air compressor below 80 DEG C, and low operating temperature changes the user cost of lubricant oil, and lubricant grease changes domestic plain oil into from import; Work at low temperatures without oily piston type air compressor, the material selection of whole component and the requirement of cold and hot machining are all declined than type similar on market, cost-saving; When air compressor inside does not produce high temperature, its energy consumption reduces, and does not need to cool air, and is working without under oil condition, and whole pressurized air is all very clean, does not need the equipment such as deaerator; Work under low-temperature condition without oily piston type air compressor, the power consumption of equipment declines, and the piston ring as have employed polytetrafluoroethylmaterial material is not easy to wear under low-temperature condition, extends the working life of equipment; Former piston compressor works under the state having oil, necessarily requires good seal performance, prevents inside from occurring the problems such as oil seepage, and existing structure makes crankcase by the closed open type that changes into, casing processing request is reduced, improves the utilization ratio of material resources, effectively reduce cost.
It should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
