Description

Pipeless Air Compressor {The pipeless air compressor}

The present invention relates to a pipeless air compressor, which is conventionally exposed to the outside to remove the pipes connected between the cylinders, and to form a simple structure by forming a flow path through which the air moves inside the air compressor is easy to maintain the pipe It relates to a lease air compressor.

In general, an air compressor refers to a device that compresses air to a required pressure and stores it in a tank or the like by using a piston, an impeller, a screw, or the like for use of air (gas).

There are quite a variety of methods and types of air compressors, but usually reciprocating or screw type is used depending on the operating environment. The reciprocating type is advantageous for high pressure, but the compression capacity is directly related to the size of the piston. The screw type has an advantage in terms of capacity since the suction, compression and discharge are continuously performed while the two screw rotors rotate, but the screw type is not suitable for high pressure compression compared to the reciprocating type.

Due to these limitations, a screw type is usually used when compressing a large amount of air at low pressure, and a reciprocating type is mainly used when compressing a smaller capacity air at a high pressure.

On the other hand, a multistage compression type air compressor is known as a kind of high pressure air compressor.

Multistage compression allows compression in a high or ultra high pressure region by allowing air to be continuously compressed in multiple stages through a plurality of air compressors when one compressor is unable to reach sufficient pressure.

Conventional multi-stage compressor air compressor is composed of a structure in which a plurality of reciprocating air compressors are sequentially connected in series, each stage is a plurality of pistons are installed in the center of the crankshaft reciprocating in accordance with the rotation of the crankshaft The compression process is performed at.

However, the multi-stage compressed air compressor combined with the reciprocating type as described above increases the size of the piston at a low stage in order to meet the required compressive capacity, thereby increasing the weight or volume of the device and miniaturizing the device. There is a limit to.

In addition, as the size of the piston rapidly decreases toward the high stage, the weight or vibration force is greatly different between the piston of the lower stage and the high stage, and the imbalance of the weight or vibration force causes noise and vibration during driving.

On the other hand, the multi-stage compression air compressor combined with the reciprocating type is provided with a pipe for moving the air between the compressor, the structure is complicated by the pipe exposed to the outside, there was a problem that the maintenance and repair of the compressor is difficult.

Therefore, as shown in FIG. 7E, the air compressed at high pressure in the first and second high pressure cylinder chambers 220 and 320 is discharged to the third and fourth discharge spaces 440 and 540, and the third and fourth exhaust pipes are discharged. It will move through the furnace (280,370).

The first cylinder 200 communicates with the third exhaust pipe 280 to form a second exhaust hole 290 connected to the cooler 600.

It moves to the third exhaust pipe 280 of the first cylinder 200, and is cooled by moving to the cooler 600 through the second exhaust hole 290 with the air compressed at high pressure in the first cylinder (200). .

At this time, the compressed air supplied to the cooler 600 is cooled by moving along the cooler 600 and is discharged to the outside through the discharge hole 610 formed in the cooler 600.
