Abstract
The utility model relates to an oil-free air compressor with an axial flow fan, which is provided with an oil-free air compressor. The utility model is characterized in that an extended shaft on the front end of a mainframe crank shaft of the air compressor is orderly and coaxially fixed with an axial flow fan, a fan belt pulley and a mainframe driving wheel; the outside of a blade wheel of the axial flow fan is provided with a fan cover, the upper end of the circumference of the fan cover is provided with an air outlet which is connected with the lower end of an air guiding cover, the air guiding cover coats the half circumference of the vertical surface of a cylinder and the upper end of the air guiding cover is covered with a cylinder cap. The rotation number of the axial flow fan is not synchronous with the rotation number of the air compressor, but is simultaneous with the rotation number of a motor. The mainframe load is not increased, and the electric power consumption is not increased. The air guiding cover makes the air generated by the fan direct blow to the cylinder cap of the cylinder of the air compressor. The experiment can prove that the design can make the temperature of a first level cylinder fall to under 100 DEG C, and can make the temperature of a second level cylinder fall to about 150 DEG C. Consequently, the normal work of a polytetrafluoro piston ring can be ensured, the air compressor can continuously operate for a long time, the performance of the air compressor is reliable and the service life is prolonged.
Description
Technical field
The utility model relates to the cooling structure of air compressor, a kind of have axial-flow blower completely without oily air compressor.
Background technique
Not only structurally have any different completely without oily air compressor and common air compressor, particularly the lubricated friction parts of need such as cylinder piston ring, guide ring have adopted and have not needed the high-abrasive material of lubricating oil filling to make.So just solved the problem that pressurized air that air compressor produces contains oil gas, thereby completely without oily air compressor be specially adapted to medicine, food, spray paint, industry such as diving operation, especially in culture fisheries such as foster shrimp, give and culture oxygenation in the pond, abstain from that greasy dirt pollutes most.Small-sized completely without oily air compressor when normal the use, first-stage cylinder compression temperature when 8-10 kilogram pressure can reach 120 ℃, secondary cylinder can reach 220 ℃.And air compressor piston ring, guide ring are to adopt poly-PTFE to make, and the upper limit of heatproof is 180 ℃ under operational pressure.Will deliquescing or chipping when these parts surpass critical temperature, lose its due effect and function, can cause other components from being damaged as untimely replacing, cause the compressor cisco unity malfunction.
Summary of the invention
The purpose of this utility model provide a kind of have axial-flow blower completely without oily air compressor, be the wear parts cooling.
This have axial-flow blower completely without oily air compressor, have completely without oily air compressor, it is characterized in that the crankshaft front end of air compressor host prolongs coaxial successively stationary axle flow fan, blower fan belt pulley, main frame drive wheel on the axle; The impeller outer of axial-flow blower has fan guard, and the fan guard circumferential upper end has exhaust outlet to be connected with the wind scooper lower end, and wind scooper coats the half cycle of cylinder facade, and last end shield cylinder cap.
The design have axial-flow blower completely without oily air compressor, for the special friction parts of giving cool, fan and main frame is coaxial, and fan adds a belt pulley, link to each other with motor by belt, can make the revolution of axial-flow blower revolution and air compressor asynchronous like this, and synchronous with the revolution of motor, do not increase main unit load, do not increase power consumption, wind scooper directly blows to the cold wind that blower fan produced on the cylinder and cylinder cap of air compressor.Through evidence, the design can make the first-stage cylinder temperature drop to below 100 ℃, and the secondary cylinder temperature drops to about 150 ℃, thereby has guaranteed poly-tetrafluoro piston ring proper functioning, prolonged the working life of air compressor, made that air compressor can turn round for a long time continuously, more reliable performance.
Description of drawings
Fig. 1 be the design have axial-flow blower completely without oily air compressor structural representation;
Fig. 2 be the design have axial-flow blower completely without oily air compressor structure right elevation;
Embodiment
Accompanying drawings the design have fan completely without oily air compressor: it comprises completely without oily air compressor, it is characterized in that bent axle 1 front end of air compressor host is prolonged, and establishes an axial-flow blower 4 at the extension shaft position of nearly main frame; The coaxial successively stationary axle flow fan 4 of host crankshaft 1 front end, blower fan belt pulley 3, main frame transmission pulley 2; Blower fan belt pulley 3 combines by bolt and axial-flow blower 4 coaxial bearing, and blower fan belt pulley 3 all is connected with the motor wheel by belt with main frame transmission pulley 2.Outside the impeller 5 of axial-flow blower fan guard 6 is arranged, be fixed on the main frame casing 10.Fan guard 6 circumferential upper end have exhaust outlet to be connected with wind scooper 7 lower ends, and wind scooper 7 coats the half cycle of cylinder 9 facades, and last end shield part cylinder cap 8.The wind that axial-flow blower produces through fan guard concentrate, supercharging, enter behind the wind scooper along the cylinder facade disperse, cylinder head fin through cyoinder cooling fin groove and cylinder top flows out.
The shape of fan guard 6 conforms to the impeller of axial-flow blower 5 profiles, and greater than impeller 5 diameters, peripheral clearance is even, be not more than 5mm, to guarantee blast, fan guard 6 leaves intake grill at impeller 5 axial ends, in circumferential upper end one or more exhaust outlets can be arranged, communicate with wind scooper 7.
When air compressor was established a plurality of cylinder, see Fig. 2: can be each cylinder and establish corresponding wind scooper, the exhaust outlet of relevant position joined on the following end interface of wind scooper and the fan guard circumference.
Claims (3)
1, a kind of have axial-flow blower completely without oily air compressor, have completely without oily air compressor, it is characterized in that the crankshaft front end of air compressor host is prolonged, at the coaxial successively stationary axle flow fan in extension shaft position, blower fan belt pulley, the main frame transmission pulley of nearly main frame, the blower fan belt pulley combines with the axial-flow blower coaxial bearing by bolt; The impeller outer of axial-flow blower has fan guard, and the fan guard circumferential upper end has exhaust outlet to be connected with the wind scooper lower end, and wind scooper coats the half cycle of cylinder facade, and last end shield the part cylinder cap.
