Air Compression Pump {THE PUMP FOR AIR COMPRESSED}

The present invention relates to an air compression pump, and more particularly, the rota shaft in the state eccentric with the center of the cylinder in the interior of the cylinder of the pump housing, but the main surface of the rota shaft is provided with a plurality of slide grooves radially and slidably A plurality of plate-shaped vanes are installed, but the annular ring is in contact with the inner end of each vane so that each vane can be slidably moved while remaining in contact with the inner surface of the cylinder during rotation of the rota shaft. Improve the pumping ability of the pump by improving vane entry and movement at low temperature, and improve the pumping efficiency by improving the sealing force by improving the contact force between the vane and the inner surface of the cylinder, preventing the pulsation (breaking and connecting) and operating noise Its small size makes it possible to improve the working environment and its simple structure makes it easy to repair and manage. It would have to be possible to reduce the production cost.

Piston pump is installed to supply air to septic tank or compressor for reciprocating movement inside cylinder and piston pump is composed of air inlet, outlet and on / off valve. Expose the problem.

⊙ As the piston repeatedly reciprocates for air intake and exhaust, the working noise is severely deteriorated,

⊙ As the piston is operated, the intake and discharge of the air are alternately made, which causes the air to be discharged intermittently, resulting in pulsation (breaking and continuation), which lowers the pumping effect.

⊙ The air intake and discharge force is gradually weakened by abrasion of the piston, so you cannot expect a stable use effect for a long time.

⊙ Due to the relatively complicated structure, it is not easy to repair and manage, and it is difficult to miniaturize the pump.

Therefore, the present invention is intended to solve all the problems caused by the conventional pump as described above. The object of the present invention is to compress and discharge the air introduced into the inlet through the rotor shaft and the vane so that the air discharge rate and pressure are improved. It improves the pumping capacity of the pump by improving vane entry and movement at low and low temperatures, and prevents pulsation (breaking and continuity) and operation noise due to low operating noise. It is to provide an air compression pump that can be easily and miniaturized and can reduce manufacturing costs.

In order to achieve the above object, the present invention lays out a rotatable shaft in a state eccentric with the center of the cylinder in the cylinder of the pump housing, but has a plurality of slide grooves radially provided on the main surface of the rotatable shaft and slidable thereto. While installing the vanes of each of the vanes rotates while maintaining the contact with the inner surface of the cylinder through the annular ring in contact with the inner end when rotating the rotatable shaft, the present invention will be described in more detail with reference to the accompanying drawings. Is as follows.

As shown in FIGS. 1 to 3, the present invention includes a pump inlet 1, an inlet 2, an outlet 3, and a circular cylinder 4, and a cylinder 4 inside the cylinder 4. The rotatable shaft 5 is eccentrically concentric with the center of the rotatable shaft 5, and both side surfaces of the rotatable shaft 5 are provided with a ring position groove 6 with a predetermined depth, and the main surface of the rotatable shaft 5 is spaced at regular intervals. A radial slide groove 7 is provided in the longitudinal direction, and a vane 8 fitted in the slide groove 7 to enable slide reciprocation and rotational movement is in contact with an annular ring 9 configured as shown in FIG. The end of each vane 8 is always configured to be supported so as to be in contact with the inner surface of the cylinder 4 of the pump housing 1.

According to the present invention, the vane 8 fitted into the slide groove 7 of the rota shaft 5 rotates with a certain amount of eccentricity when the pump operates, and the inner surface of the cylinder 4 in the pump housing 1. The pumping action is caused by relative motion.

At this time, the outer end of the vane 8 located in the rotatable shaft 5 is brought into contact with the inner surface of the cylinder 4 by an annular ring 9 mounted in the rotatable shaft 5 when the pump is first driven to maintain sealing properties. A partition having different occupied spaces is provided between the inner surface of the cylinder 4 and each vane 8, and the space between the inner surface of the cylinder 4 and the rota shaft 5 becomes larger and the vanes become larger toward the suction port 2. (8) protrudes from the rotatable shaft (5) to induce more air intake, the space between the inner surface of the cylinder (4) and the rota shaft (5) narrows toward the outlet (3) side and the vanes (8) It is immersed in the rotatable shaft 5 to induce the compression and discharge of air.

On the other hand, when the air is sucked in from the inlet port 2 by the driving of the rota shaft 5, the air between the vane 8 and the inner surface of the cylinder 4 is moved toward the outlet port 3 and gradually compressed to the reduction of the receiving space, and the outlet port. In (3), the pump is discharged with rapid and strong pressure.

In the above, both sides of the rotatable shaft 5 are provided with annular rings 9 so that the inner ends of the vanes 8 are in contact with each other, thereby suppressing the retreat of the inner ends of the vanes 8. The cylinder 4 can be rotated while remaining in contact with the inner surface of the cylinder 4 without falling off.

In addition, since the plurality of vanes 8 are continuously rotated, the compressed air received between each vane is continuously discharged to the discharge port 3, so that the pulsation phenomenon of intermittent discharge flow is prevented when the air is discharged.

As described above, the present invention improves the discharge speed and pressure of the air, and improves the pumping ability of the pump by making the vane move out at low and low temperatures, and the outer end of the vane is always cylinder through the annular ring. It can be rotated and floated while maintaining contact with the inner surface to improve the working environment by increasing pumping efficiency, preventing pulsation (breaking and continuation), and reducing operating noise. It is easy to manage and can be miniaturized, which can reduce the manufacturing cost.
