Description

Rotary Disc Pump

The present invention relates to a rotary disk pump in which a rotary disk is configured to pump a fluid, and more particularly, is configured to offset a vacuum due to cavitation generated in a space between the disk and the housing, thereby increasing pumping efficiency. The present invention relates to a rotary disk pump that can reduce noise.

Rotary disk pumps used for common fluids include a housing (2) having a cylindrical rotor chamber (1) therein as described in Korean Patent Publication No. 178546 and FIG. 3, and one end of the chamber (1). At least two parallelly spaced disks disposed coaxially within the chamber 1 and connected so as to rotate together about their central axis 5 and having an inner facing surface, 6), wherein the inner opposing surfaces of the disk 6 are spaced a predetermined distance apart during rotation to pump the fluid.

In the conventional rotary disk pump as described above, when the disk 6 rotates in the chamber 1 by the driving of the motor 7, the chamber 1 is in a vacuum state, and thus the fluid flows through the inlet 3. It sucks in and discharges it to the outlet 4.

However, in the conventional rotary disk pump as described above, when the disk is rotated to move the fluid from the inlet to the outlet, cavitation occurs in the space between the housing and the disk, thereby reducing the pumping efficiency of the fluid and increasing the noise. There was a problem.

The present invention has been proposed to solve the above conventional problems, and an object of the present invention is a rotary disk pump, which is generated by cavitation generated in the space between the disk and the housing according to the rotation of the disk. It is to provide a rotary disk pump configured to offset the vacuum to prevent the pumping efficiency is lowered and to prevent the generation of noise at the same time.

The rotary disk pump of the present invention for achieving the object of the present invention as described above, the housing having a cylindrical rotor chamber therein, the inlet and outlet at one end of the chamber, and is disposed coaxially in the chamber and the center thereof A conventional rotary disk pump comprising a disk connected to rotate about an axis, the disk having an inner facing surface, the inner facing surface of the disk being spaced apart a predetermined distance upon rotation to pump the fluid;
A space between the disk and the inner wall of the housing is provided with a passage connected to the inlet to allow fluid to flow therein;
The passage is configured to connect a space between the inlet and the disk and the inner wall of the housing through the interior of the housing to supply fluid from the inlet to the inner wall of the disk and the housing.

And the passage is formed in the interior of the inlet is located in the inlet is characterized in that the discharge port is located on the inner wall of the housing of the space between the disk and the inner wall of the housing.

The rotary disk pump of the present invention made as described above, when the disk is rotated to move the fluid from the inlet to the outlet as described above, by the cavitation (cavitation) generated in the space between the disk and the housing according to the rotation of the disk The generated vacuum is canceled by the fluid supply on the inlet side flowing through the passage, thereby preventing the pumping efficiency from dropping, and also preventing the generation of noise.

2 is a partially enlarged schematic illustration of FIG. 1.
Figure 3 is a schematic cross-sectional view showing a conventional rotary disk pump.

Hereinafter, a rotary disk pump according to a preferred embodiment of the present invention with reference to the accompanying drawings in detail as follows.

1 and 2 show a rotary disk pump according to an embodiment according to the present invention. The rotary disk pump according to the present embodiment includes a housing 2 having a cylindrical rotor chamber 1 therein, and the chamber. Inlet 3 and outlet 4 at one end of (1) and a disc 6 arranged coaxially within said chamber 1 and connected to rotate about its central axis 5 and having an inner facing surface 6 ).

The inner facing surface of the disk 6 is also spaced apart a certain distance during rotation to pump the fluid.

And the disk 6 in the chamber 1 is preferably formed at least two parallel spaced apart coaxially within the chamber 1 and connected to rotate together about its central axis 5.

Therefore, when the disk 6 is rotated inside the chamber 1 when the central shaft 5, which is powered by the motor 7, is rotated, the chamber 1 has a vacuum state.

The fluid is thus pumped through the inlet 3 to the outlet 4.

In the rotary disk pump according to the present embodiment, a space 9 between the disk 6 and the inner wall 8 of the housing 2 is connected to the inlet 3 to allow fluid to flow therein.

Thus, when the disk 6 rotates to move fluid from the inlet 3 to the outlet 4, it is created in the space 8 between the disk 6 and the housing 2 as the disk 6 rotates. When the vacuum is generated by the cavitation, the fluid located at the inlet 3 through the passage 9 is sucked by the generated vacuum to cancel the vacuum.

Accordingly, the pumping efficiency is lowered and noise is prevented from occurring.

In addition, the passage 9 is formed inside the housing 2, the inlet 10 is located at the inlet 3, and the space 8 between the disk 6 and the inner wall of the housing 2. The discharge port 11 is formed on the inner wall of the housing 2.

That is, since the passage 9 is provided inside the housing 2, no separate connection means for constituting the passage 9 does not need to increase the production cost.

And the housing 2 is preferably composed of a plurality of parts formed in the passage (9) therein, in this case, the fixing grooves dug inwardly in the connection portion of the passage (9) formed in the parts It is most preferable that the sealing groove 12 is formed in the fixed groove is formed.

Therefore, the fluid does not leak by the sealing ring 12 and is discharged to the discharge port 11 smoothly.

Referring to the operation and effect of the rotary disk pump of the present embodiment made as a singer in detail as follows.

When the disk 6 is rotated to pump fluid from the inlet 3 to the outlet 4 using the rotary disk pump of the present embodiment, the disk 6 and the housing 2 of the disk 6 are rotated according to the rotation of the disk 6. A cavitation phenomenon is generated in the interspace 8, and thus a vacuum is generated in the interspace 8 of the disc 6 and the housing 2.

When a vacuum is generated in the space 8 between the disc 6 and the housing 2 as described above, the fluid is vacuum sucked through the inlet 10 of the inlet 3 through the passage 9 by the generated vacuum. It flows into the discharge port 11.

Accordingly, as the vacuum generated in the space 8 between the disk 6 and the housing 2 is canceled out, the pumping efficiency is not lowered and noise is not excessively generated.
