The present invention relates to a pump for compressing air or conveying amniotic fluid or oil or chemical liquid, and to provide a rotary pressure pump having a strong vacuum force by having a cylinder and a piston in a rotor and a rotor in a body.

Among the conventional pumps, the piston is built in the cylinder to reciprocate. It is made of metal, and the ring fitted to the outer circumference of the piston scratches the inner wall of the cylinder. Used metal positive pump is mainly used for pumping water, and the impeller or casing inside contact with water is oxidized and cannot be used for a long time, and its weight is heavy so that it is not easy to transport. When an impeller is installed in the fuselage, when the impeller is rotated, the displacement rotates together in close contact with the upper surface of the inner diameter of the fuselage to generate a major force because the displacement does not generate a strong vacuum force. It could be used as a deep water pump.

The present invention corrects the above-mentioned defects as described above, and evenly forms the outer circumference of the rotor, which is rotated in the fuselage to minimize the wear rate, like a mirror surface, so as not to scratch the inner circumference of the fuselage. A rectangular parallelepiped cylinder is formed in this cylinder to generate a strong vacuum force so that it can also be used as an air compression pump or a pump for deep groundwater. It will be described in detail as follows.

In the case where the lids 4 and 5 are covered with a bowl in front and rear of the fuselage 3 which connects the inlet pipe 1 and the drain pipe 2 to the inlet pipe 1 side and the drain pipe ( 2) When the cylindrical rotor 6 is installed in the body 3 in an elliptical shape so that the diameter of the side is larger than the upper and lower parts, the inner space 7 is formed on the inlet pipe 1 side and the drain pipe 2 side. (8) is formed, and the cover (4) (5) is drilled through the shaft holes (9) and (10) in the lower side of the middle and the gears (11) and (12) in the shaft holes (9) and (10) on the inner surface side. The power source is connected to the gear side 13 penetrated from the outside of the cover 4, and the gears 11 and 12 are bored with eccentric holes 14 and 15, and the circumferential rotor ( 6) the inner diameter gears (16) and (17) are formed on both ends, and the inner cylinder gears (16) and (17) form a rectangular parallelepiped cylinder (18), and both ends have connecting shafts (19, 20). Insert the rod-shaped piston 21 into the cylinder 18 and then insert the rotor 6 into the body 3. The piston 21 has a cover (4) and (5) in the fuselage (3) so that the connecting shaft (19) (20) fits in the eccentric holes (14) (15) of the gear (11) (12). ) It is designed to be assembled by covering with a bolt in front and rear.

The present invention as described above allows the upper and lower surfaces of the rotor 6 to rotate in close contact with the middle upper and lower surfaces of the inner diameter of the body 3, and the gears 11 and 12 are connected to the inner diameter gears 16 and 17. The rotor 6 is idling in the second direction along the gear 11 coupled and rotated by the power transmission of the gear shaft 13, and the eccentric holes 14 and 15 of the gears 11 and 12. The piston 21 is rotated by the connecting shaft 19, 20 inserted in the state maintaining the diameter for the circumference of the eccentric hole 14, 15 is rotated, such rotation and the rotor (6) As the cylinder 18 is rotated, the piston 21 acts to reciprocate in the cylinder 18, and the present invention is to distinguish the suction action and the discharge action, the fourth (a) or suction operation In this state, when the rotor 6 rotates in the clockwise direction as shown in FIG. 4 (b), the cylinder 18 also rotates together, and at this time, the gears 11 and 12 rotate. The piston 21 is slightly rotated accordingly, but slightly rises in the cylinder 18, so that a space is formed at the lower end of the cylinder 18 below the piston 21 so that the space generates a vacuum state, and thus, the inner space 7 The amount of liquid as the space formed by the movement of the piston 21 is introduced from the inlet pipe (1), the fourth (c) is a state diagram in which the suction action of the piston 21 is finished, in this case the piston 21 is The suction space in the cylinder 18 is wider than that of the fourth (b) degree, so that the amount of liquid flowing from the inlet pipe 1 is greater and the suction action is finished, and the fourth (d) degree discharge operation As an illustration, at this time, the space in the cylinder 18 in which the piston 21 is moved gradually decreases as the piston 21 continues to move in the longitudinal direction of the cylinder 18, thereby naturally decreasing the space in the cylinder 18. Will be pushed in) It is to be discharged through the drain pipe (2).

In more detail, the liquid flowing from the inlet pipe 1 is not discharged into the drain pipe 2 through the cylinder 18, but the piston 21 is a gear 11 indicated by the origin line as shown in FIG. Of the cylinder 18 while rotating around the night It is reciprocated as much as the length, but the result is reciprocated by the entire length of the cylinder 18, it occurs on both sides of the left and right by dividing the entire length of the suction and discharge action cylinder 18 in two, as described above By the repeated suction action of (21), the liquid flowing in from the inlet pipe 1 is filled in the inner space 7 and then filled into the inner space 8, thus covering the entire inner space 7 and 8. In the filled state, the liquid is obtained from the water inlet pipe (1) according to the suction and discharge action of the piston 21 is discharged to the drain pipe (2).

In this way, the present invention was designed so that the piston 21, which is rotated according to the eccentric holes 14 and 15, reciprocates in the cylinder 18 that is rotated by the rotation of the rotor 6 to perform the suction and discharge action separately. The strong suction and drainage power makes it suitable for deep groundwater pumps as well as air compression pumps. The rotor 6 is idling in the fuselage 3 and the movement distance of the piston 21 is short, so the wear rate is extremely low. In addition, the configuration is also simple, if made of a wear-resistant synthetic resin will exhibit an easy operation or transport work.
