Description

Noiseless Air Compressor {Noiseless aircompressor}

The present invention relates to a noiseless air compressor, in particular to solve the frictional heat of the horizontal piston system in the horizontal piston system having a high frictional heat to realize a noiseless air compressor.

In general, a refrigeration compressor is a device that compresses and circulates refrigerant gas. A crank shaft for converting the rotational motion of a piston, a cylinder, an electric motor, and an electric motor into a linear motion for compressing the refrigerant gas, and a low pressure for suction and discharge of the refrigerant gas. It is equipped with a port and a high pressure port.

These basic components are housed in a hermetically sealed case, which acts as a container to prevent mechanical noise during piston operation and to store lubricating oil. At this time, the refrigeration compressor is a low noise type less than 3 hp Compressor is based on hermetic type.

When compressing air other than refrigerant gas with a refrigeration compressor, the refrigeration compressor can also be used temporarily as an air compressor because it is a kind of compressor, but the compressed air generated at this time contains a large amount of lubricating oil, which is not suitable for compressed air. Problems with lubrication will cause compressor failure.

When compressing air with a refrigeration compressor, moisture in the air flowing into the low pressure port drips in the case, causing rust and increasing the viscosity of the lubricating oil, which does not start during operation of the refrigeration compressor or damages the starting coil. Will cause.

In addition, when the piston reciprocates for air compression, lubricating oil is sprayed into the crank shaft including the piston and scattered in the case along the lubrication groove made in the shaft of the electric motor.

At this time, the low pressure side of the cylinder is sucked with air as well as scattered sprayed lubricant is compressed and transported to the high pressure side.

Thus, the lubricant in the case is easily depleted and too much lubricant is contained in the compressed air, making it unsuitable where clean compressed air is required.

In addition, the refrigeration compressor is very sensitive to lubrication, and when compressing air, not refrigerant gas, selection of lubricating oil is very difficult, and when lubricating oil is inadequate, noise or start-up occurs when starting.

Another problem with compressing air with refrigeration compressors is the heat generated during compressor operation.

Refrigeration compressor solves heat problem by naturally cooling compressor by cooling action of lubricating oil which is another function of lubricating oil and circulating refrigerant gas, but there is no cooling means except cooling by lubricating oil when air is compressed. Without a separate cooling system, starting of the motor will be impossible or coils will lose heat.

On the other hand, the compact refrigeration compressor is an excellent compressor mainly developed for home appliances to minimize noise and to obtain the best compression ratio in a small size.

The refrigeration compressor solves the problems listed above and can produce a compact, noiseless high pressure air compressor.

In the case of the conventional air compressor, the noise is high in the case of the vertical piston using the belt, even in the case of the V-shaped piston method or the screw (Screw) method using the belt.

On the other hand, in the case of a horizontal piston, there is little noise and power is good, but the friction heat is so severe that it is impossible to use.

The present invention is to solve such a conventional problem, the object of the present invention is a horizontal piston system with little noise and good power, but the frictional heat is extreme, solving the frictional heat of the horizontal piston method, a noiseless air compressor To provide.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the appearance of the air compressor 11 applied to the present invention, Figure 2 is a cross-sectional view of the main portion of the air compressor (11) according to the present invention.

A low pressure port (1A) for refrigerant suction is formed on one side, and a case (1) having a high pressure port (1B) for discharging the compressed refrigerant on the other side, and located in the inner lower portion of the case (1) to perform a cooling function A cooling lubricating oil (2) to be installed, an electric motor (3) having a low speed rotational speed installed at an inner lower portion of the case (1) and rotating at a predetermined speed, and one side of which is fixedly installed on a rotating shaft of the electric motor (3), The other side is rotatably installed on the connecting rod is coupled to the crankshaft (4) and the upper part of the case (1) to receive the driving force of the electric motor (3) to allow the piston to reciprocate linearly inside the cylindrical body The cylinder 5, the piston 6 is inserted into the inside of the cylinder 5 closely and reciprocates left and right, and one side is rotatably installed on the piston 6 via a connecting pin. The side is connected to the crankshaft (4) A rod 7, a connecting pipe 8 for moving the air introduced through the low pressure port through the cylinder to the high pressure port, and a cover installed on the outer upper part of the case 1; 10) the exhaust fan 9 is installed at the top to discharge heat generated from the compressor 11 to the outside.

However, by connecting the low pressure port 1A and the lower side of the cylinder 5, the intake air may be configured to discharge only the compressed air and water as it is without the lubricating oil 2 through the cylinder 5.

Referring to the operation of the present invention configured as described in detail as follows.

First, when electric power is applied to the electric motor 3 to drive the electric motor 3, the rotating shaft 3A of the electric motor 3 rotates at a predetermined | prescribed rotational speed, and the crankshaft 4 also rotates by this.

Therefore, when the crankshaft 4 rotates, the piston 6 performs a linear reciprocating motion from side to side while in close contact with the inner wall surface of the cylindrical body 5A of the cylinder 5 via the crankshaft 4. Done.

That is, when the piston 6 moves to the left side, air is introduced from the low pressure port 1A provided on one side of the case 1 while the air inlet of the cylinder 5 is opened.

On the contrary, when the piston 6 moves to the right, the air remaining in the cylinder 5 is closed while the air inlet of the cylinder 5 is closed.

Thus, the compressed air compressed in the cylinder 5 is transferred to the high pressure port 1B through the connecting pipe 8 and then to the air tank through another connecting pipe or the like.

At this time, when the low pressure side pipe of the cylinder 5 and the low pressure port 1A outside the case 1 are directly connected to each other, the sucked air flows directly into the cylinder 5 and then is compressed to the outside through the high pressure port 1B. Lubricating oil (2) is mixed in the compressed air generated by being transferred to the air tank connected to the compressor 11, and moisture generated by the air is not generated in the compressor (11), and the lubricating oil (2) sprayed during the operation of the piston (6) is not sucked. It doesn't work.

However, since the pipe is directly connected to the noise, it should be flexible enough to absorb vibrations during piston movement.

On the other hand, lubrication is very important in the refrigeration compressor, in the case of the refrigerant gas may be used according to the lubricating oil (2), but when compressing air, the lubricating oil (2) will determine the performance of the compressor.

Therefore, the present invention realizes the optimum performance and noise reduction by using the lubricating oil (2) mixed with special additives. High horsepower achieved by Nst + cooling means.

The Nst is primarily obtained by performing an aging process (AGING PROCESS) through a repetition of an instantaneous high temperature treatment and a predetermined ultra low temperature treatment at a high temperature, and secondly aging surface treatment with a mixed gas under an appropriate pressure using a gas.

3 shows another embodiment of the present invention, which shows an air compressor in which the electric motor 3 part and the cylinder 5 part are replaced in FIG. 2, and the same reference numerals are used for the same parts.

Also in this embodiment, when the crankshaft 4 rotates as the electric motor 3 is driven, the piston 6 is in close contact with the inner wall surface of the cylindrical body 5A of the cylinder 5 via the crankshaft 4. The linearly reciprocating motion to the left and right while rubbing, so that the compressed air compressed in the cylinder (5) is transferred to the high pressure port (1B) through the connecting pipe (8) and then to the air tank through the other connecting pipe, etc. will be.

In this case, the lubricating oil 2 is scattered and sprayed during the operation of the piston 6, and the lubricating oil 2 can be realized by using a special additive as described above to achieve optimum performance and noise reduction.

The present invention as described above, in the air compressor, performing the aging process (AGING PROCESS) through the repetition of the instantaneous high temperature treatment and a predetermined cryogenic treatment at a high temperature, the surface treatment for a long time with a mixed gas under a suitable pressure using gas By using lubricating oil obtained through Nst to achieve optimum performance and noise reduction, low horsepower is realized by using Nst (Natural Saint Technology) + fan, and the effect of realizing high horsepower by Nst + cooling means have.
