Description

Vacuum self-priming pump driving gear

The present invention relates to a vacuum ferromagnetic pump that pumps liquid by vacuum suction, and indirectly transfers the driving force of the motor to the impeller to prevent damage to the motor and the impeller and to prevent leakage in the casing without the need for the installation of a sealing device. A drive device for a vacuum ferromagnetic pump.

The vacuum ferromagnetic pump, which is designed to pump water or high-viscosity liquid in both the inlet and outlet ports, has been registered in the patent application No. 175650. The vacuum ferromagnetic pump has a radial wing. The impeller rotates at a high speed by driving a motor to pump the suction.

Such a conventional vacuum ferromagnetic pump 1 is provided with a suction port 7 and a discharge port 8, as shown in Figs. 1 and 2 of the drawing and U-shaped transfer grooves 2a and 3a to which suction is conveyed. The inner casing (2) and the outer casing (3) provided inside the radially between the inner and outer casing (2) (3) is coupled to the axial direction of the motor (4) and the transfer groove (2a) (3a) An impeller 6 having wings is interpolated and fitted to the motor shaft 5 to be mounted.

Therefore, the impeller mounted in the inner and outer casing rotates at high speed by the high speed rotation of the motor to make the transfer groove in a vacuum state, and pumps water or high viscosity liquid by vacuum suction to the suction port.

In the conventional vacuum ferromagnetic pump, the impeller is inserted into the inner and outer casings of the motor shaft, so that the driving force of the motor is transmitted directly to the impeller. The driving force is not cut off, which causes a problem that the impeller and the motor are damaged.

In addition, since the impeller is fitted to the motor shaft and mounted in the inner and outer casings, a sealing device for sealing is required between the motor shaft and the inner casing, while the sealing device is worn out by continuous driving of the motor. .

The present invention has been devised to solve the problems of the conventional vacuum ferromagnetic pump as described above, by indirectly transferring the driving force of the motor to the impeller by using a magnet to block the driving force of the motor to prevent damage to the motor and the impeller. It is an object of the present invention to prevent leakage in the casing without the need for mounting a sealing device.

The present invention is equipped with a large diameter magnet on the motor shaft while the impeller is equipped with a small diameter magnet to transfer the driving force of the motor by the magnetic force of the magnet, the present invention in FIGS. Detailed configuration is shown.

The present invention has an outer casing (3) provided with a suction port (7), a discharge port (8), and a U-shaped conveying groove (3a), and an inner casing (2) having a space therein and coupled to the axial direction of the motor (4). ), A rotating cap 10 to which the prime magnet 11 is attached to the motor shaft 5, an impeller 6 on which the driven magnet 21 is mounted on one side, and a driven magnet 21 and an impeller ( 6) is interpolated and consists of an impeller cap 20 coupled between the inner and outer casings 2 and 3.

The outer casing 3 may have a conventional structure in which a suction port 7 and a discharge port 8 are formed, and a U-shaped transfer groove 3a through which the suction is transported is provided, and the inner casing 2 is located inward. It takes a cylindrical shape with a space and is coupled to the axial direction of the motor 4.

On the motor shaft (5) placed in the inner casing (2) is fitted with a rotary cap (10) with a moving magnet (11) attached, the rotating cap (10) is inserted into the inner casing (2) of the central motor shaft ( 5) The outer periphery, which is mounted on and given a space inside, has a large diameter close to the inner periphery of the inner casing 2, and attaches a cylindrical prime mover 11 to the inner periphery.

The impeller 6 may adopt a conventional structure having radial wings, and is attached to protrude a cylindrical driven magnet 21 having a diameter smaller than the motive magnet 11 on one side, and the washers are fastened to both ends at the center. Shaft 24 is rotatably fitted.

Here, although the primary magnet 11 and the driven magnet 21 may use a general cylindrical magnet, it is preferable to use a magnet having a stronger magnetic force.

The structure of attaching the driven magnet 21 to one side of the impeller 6 inserts the driven magnet 21 into the case 22 and inserts the impeller 6 into the side of the case 22 to insert the case 22 and the impeller. The pins 25 may be fixed between the pins 6, and other combinations of known techniques may be adopted.

The impeller cap 20 into which the impeller 6 with the driven magnet 21 is inserted is provided with a space in which the impeller 6 is inserted into the outer casing 3, and the inner side of the driven magnet 21 and the case ( 22 is inserted into the insertion cup 23, the insertion cup 23 is protruded to be interpolated in the motive magnet 11 of the rotating cap 10 mounted on the motor shaft (5) and the motive magnet 11 and The driven magnet 21 is configured to receive mutual magnetic force.

Impeller cap 20 is placed between the inner and outer casing (2) (3) and coupled to the fastening bolt 26, the impeller 6 attached to the driven magnet 21 is the outer casing (3) and the impeller cap (20) The shaft 24 is fitted in and rotatably interpolated.

Therefore, a strong magnetic force acts between the driving magnets 11 and the driven magnets 21 facing each other indirectly and is in a attracting state. Therefore, when the rotation cap 10 and the driving magnets 11 are rotated by the driving of the motor 4. Driven by the magnetic force of the magnet 11, the driven magnet 21 is rotated to drive the impeller (6).

The distance between the prime magnet 11 and the driven magnet 21 is small, and the magnet has a high Gaussian magnet so that the magnetic force acts strongly. Here, the magnet is manufactured in consideration of the driving force of the motor 4 and the load of the impeller 6. desirable.

According to the present invention having the above configuration, when the rotating cap 10 and the moving magnet 11 mounted on the motor shaft 5 rotate as the motor 4 is driven, the insertion cup 23 of the impeller cap 20 is rotated. The driven magnet 21 placed is rotated by the magnetic force of the prime mover 11 to rotate the impeller 6.

The impeller 6 and the driven magnet 21 placed in the impeller cap 20 are rotated at high speed on the shaft 24 to make the transfer groove 3a of the outer casing 3 vacuum and suck the liquid into the suction port 7. It is pumped to the discharge port (8).

In the pumping process, foreign matter is caught in the impeller 6, the outer casing 3, and the impeller cap 20 so that a load greater than the magnetic force acting on the motive magnet 11 and the driven magnet 21 acts on the impeller 6. The impeller 6 is stopped while the motor 4, the rotating cap 10, and the motive magnet 11 are rotating to prevent the motor 4 and the impeller 6 from being damaged.

The present invention is such that the impeller 6 and the driven magnet 21 is sealed to the impeller cap 20 and the outer casing 3 and indirectly receives the driving force of the motor 4 to pump the liquid to prevent leakage. As such, the mounting of the sealing device on the motor shaft 5 is unnecessary.

The present invention indirectly transfers the driving force of the motor to the impeller by the driving magnet and the driven magnet, thereby preventing the damage of the impeller and the motor by immediately blocking the driving force of the motor when foreign matter gets stuck, and preventing the leakage of the sealing device. The pumping power is improved by increasing the vacuum suction input.
