Description

[0001] FLUID PUMP STRUCTURE HAVING FLUID SENSOR [0002]

The present invention relates to a fluid pump, and more particularly, to a fluid pump that includes a fluid sensor for detecting whether fluid is flowing through an inlet pipe, To a fluid pump for preventing damage from occurring.

Generally, a fluid pump is a device that applies pressure to a gas or liquid fluid and transfers it to one side. Such pumps are widely used in industrial and general life, and especially in the semiconductor industry and pharmaceutical industry, they are used for stable pumping of chemicals or liquids.

As a conventional example of such a fluid pump, Patent Document No. 1237020 discloses a technique related to a fluid pump having improved waterproofness.

However, in the above-mentioned conventional fluid pump, even if the fluid is not introduced through the inflow pipe, the motor is continuously driven, so that the motor is overheated due to idling of the impeller, There has been a problem in that it occurs.

The present invention has been proposed in order to solve the problems of the prior art described above and provides a technology for stopping the driving of the motor when the inflow of the fluid is not carried out so that the overheating of the motor and the damage of the pump are prevented There is a purpose for this.

According to an aspect of the present invention, an impeller housing is connected to one side of a motor housing having a drive motor therein, and an impeller for receiving a rotational force from a drive motor is formed in the impeller housing. And a fluid discharge port through which fluid introduced into the fluid discharge port is formed is formed on the other side of the impeller housing, wherein the fluid inlet and the fluid discharge port are provided with a fluid sensor for sensing fluid, Respectively; And a control unit for on / off control of the driving motor according to a detection signal from the fluid sensor is formed at one side of the motor housing.

The present invention has the effect of preventing overheating of the motor and occurrence of pump damage by temporarily stopping the driving motor when no fluid is detected in the fluid inlet and fluid outlet of the fluid pump.

1 is a schematic structural view of a fluid pump according to an embodiment of the present invention;
2 is a magnified view of a fluid inlet side according to another embodiment of the present invention.
3 is a magnified view of a fluid inlet side according to another embodiment of the present invention.
4 is an elastic pad separation diagram in still another embodiment of the present invention.

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

First, a fluid pump according to an embodiment of the present invention will be described with reference to FIG.

An impeller housing 20 is connected to one side of a motor housing 10 having a drive motor 11 therein and an impeller 21 for receiving a rotational force from the drive motor 11 is disposed in the impeller housing 20, A fluid inlet 22 through which the fluid flows is formed at one side of the impeller housing 20 and a fluid outlet 23 through which the fluid introduced into the impeller housing 20 is discharged is formed at the other side of the impeller housing 20 The fluid pump according to claim 1, wherein the fluid inlet (22) and the fluid outlet (23) are provided with fluid sensing sensors (30, 40) 40 for controlling on / off of the driving motor according to a detection signal.

An inlet pipe and a discharge pipe are connected to the fluid inlet 22 and the fluid outlet 23, respectively, but not shown in the drawing.

Hereinafter, the operation and effect of driving the fluid pump of the present invention will be described.

The power is supplied to the driving motor 11 mounted in the motor housing 10 so that the impeller 21 rotates at a high speed and flows into the fluid inlet 22 by the operation of the impeller 21. [ The fluid is discharged through the fluid discharge port 23.

At this time, since the fluid sensing signals are transmitted from the fluid sensing sensors 30 and 40 provided at the fluid inlet 22 and the fluid outlet 23 to the controller 50, the operation of the driving motor 11 is continuously performed .

When the fluid is not supplied through the fluid inlet 22 while the impeller 21 is continuously operated, the fluid sensors 30 and 40 detect the fluid and the abnormal signal is transmitted to the controller 50 At this time, the control unit 50 performs control to turn off the operation of the drive motor 11.

Accordingly, when the inflow of the fluid is not performed, the operation of the drive motor 11 is stopped promptly, thereby preventing the drive motor 11 from overheating and preventing the damage of the pump.

When the supply of the fluid through the fluid inlet 22 is resumed, a sensing signal is transmitted from the fluid sensor 30 provided in the fluid inlet 22 to the controller 50, thereby driving the driving motor 11 .

2 shows a structure according to another embodiment of the present invention. The fluid sensing sensor 30 formed on the fluid inlet 22 side is connected to an elastic spring (not shown) so as to be spaced apart from the bottom surface of the fluid inlet 22 31). ≪ / RTI >

Since the fluid sensing sensor 30 is supported at a predetermined height from the bottom surface, the fluid is sensed only when the fluid flowing through the fluid inlet 22 is above a certain level, Can be improved.

In addition, the vibrations and shocks generated by the pump are absorbed by the elastic force of the elastic spring 31, so that the vibration transmitted to the fluid sensor 30 is reduced, thereby preventing sensor failure.

3 and 4 illustrate a structure according to another embodiment of the present invention in which the elastic spring 31 is surrounded by a cylindrical sponge elastic pad 32 so that the fluid sensor 30 A fluid guide hole 33 is formed in the elastic pad 32 for minimizing the flow of fluid and a lubricating coating layer 34 made of lubricant Teflon is formed on the inner wall surface of the elastic pad 32 ) Is formed.

With this structure, the fluid sensing sensor 30 is provided with a double elastic support by the elastic spring 31 and the elastic pad 32, so that the vibration buffering effect can be further maximized.

Further, since the fluid flow through the fluid guide hole 33 can be made and the lubricating coating layer 34 is formed on the inner wall surface of the elastic pad 32, the frictional force with the fluid can be minimized, And the flow of the fluid can be smoothly performed.

Although specific embodiments of the present invention have been described and illustrated above, it is to be understood that the fluid pump structure of the present invention can be variously modified by those skilled in the art.

It should be understood, however, that such modified embodiments are not to be understood individually from the spirit and scope of the invention, and such modified embodiments are intended to be included within the scope of the appended claims.
