Description

Air-cooled big discharge capacity reciprocating piston air compressor

Affiliated technical field

The utility model relates to a kind of air compressor, especially air-cooled big discharge capacity reciprocating piston air compressor.

Background technique

At present, domestic traditional big capacity compressors (refers to air displacement 15-30M ³/ min, exhaust pressure 0.7-1.25MPa) adopt L type water-cooled double-action methods for cooling, on the one hand, and complex structure, operating difficulties, in the using process, sufficient water source is essential, cause water resource waste, and cost of investment is excessive; Adopt the form of V-structure, realize big air-cooledization of discharge capacity air compressor, essential vat warp causes the upper thread that is cooled excessive, causes an end normally to be cooled off, the other end can not normally be cooled off, cause machine overheated, the oil consumption height, structure is excessive, and because a foundry goods two ends excessive temperature differentials, and cause the machine internal stress to rupture greatly.

Summary of the invention

In order to overcome the in-problem deficiency of existing air compressor, the utility model provides a kind of novel air-cooled big discharge capacity reciprocating piston air compressor, the air-cooled big discharge capacity reciprocating piston air compressor of this kind, not only overcome the Applicable scope of existing compressor, and expand to the abominable areas of physical environment such as anhydrous, no electricity, it is simple to operate, does not need the water source cooling, by the Forced Air Convection cooling.

The technological scheme that its technical problem that solves the utility model adopts is: air-cooled big discharge capacity reciprocating piston air compressor is in middle crankcase body bent axle to be arranged, stretch out outside the crankcase body on the left side, bearing and left bearing lid is arranged on crankcase body, the left side of bent axle is fixed with flywheel and coupling, the right-hand member of bent axle has bearing and envelope that the right bearing lid is arranged on crankcase body, the outer upper fixed of crankcase body has three pairs to line up one of W type, secondary cylinder, be respectively one above the cylinder, the secondary cylinder lid, the side of having, cylinder cap upper end lid, piston is arranged in the cylinder, piston is connected with the microcephaly of connecting rod, and connnecting rod big end puts in the crankcase body, is connected on the bent axle with connecting-rod bolts, the lower end of connecting rod is fixed with hits spindle, crankcase the right has axial-flow blower successively, fan, radiator, there is loam cake the top of radiator, and the bottom is a lower cover, on covered safety valve, the loam cake left end has straight tube and bend pipe to be connected with air compressor, and oil box is equipped with in the lower end of crankcase body, and crankcase body is equipped with four easing valves for outer four jiaos.

Air-cooled big discharge capacity reciprocating piston air compressor, its arrangement is the W type, (direction that refers to wind blows to compresser cylinder from middle radiator by axial-flow blower to the type of cooling in order to force blowing (air draught) cooling compressor intermediate heat sink by axial-flow fan special, or in the other direction), that intermediate heat sink structural type has is board-like, tubular type, fin tube type, plate and fin type, and material has copper material and steel.

Air-cooled big discharge capacity reciprocating piston air compressor, reciprocating piston structure adopt the crankshaft-link rod piston mechanism to realize that crankshaft rotating moves to the conversion of reciprocating motion of the pistons, thereby realize the compression process of gas.Crankshaft stroke 110mm-160mm (being crank throw radius 55mm-80mm), the diameter of piston, cylinder is 150mm-290mm.

The lubricating structure of air-cooled big discharge capacity reciprocating piston air compressor adopts oil pump and hits the spindle double-action, guarantees that the abundance of equipment is lubricated, and, the oil cutting-off protection facility on electric controller, is equipped with.

Air-cooled big discharge capacity reciprocating piston air compressor can be supporting with motor, diesel engine, permissible motor, is made into fixing, mobile, the serial air compressor of flame proof, unit; Thereby having solved L type water-cooled double acting compressor can not use at anhydrous, areas without electricity; Can not be at any time, everywhere, the problem that moves at random.Expanded the practical space of compressor.

Air-cooled big discharge capacity reciprocating piston air compressor adopts two parallel connections of easing valve, and suction port is arranged at air-cooled big discharge capacity series reciprocating piston air compressor two ends, can adjust compressed air require at random.

The beneficial effects of the utility model are, adopt the W type to arrange, and machine length is little, do not need the water source cooling; By the Forced Air Convection cooling, cooling is concentrated, and is simple to operate, convenient.
