Description

Technical Field

[0001] The utility model relates to the technical field of water ring vacuum pumps, in particular to a water ring vacuum pump system. Background Art

[0002] Chip factories have relatively high requirements for the size of equipment because the cost of site decoration (clean room) is very high. Therefore, the size of the equipment needs to be as small as possible to reduce the floor space occupied and reduce the cost of factory construction.

[0003] Water ring vacuum pumps require a constant supply of water, both as a working medium and as circulating water for cooling. The current approach involves using an oversized water tank to accommodate both the water medium and the cooling function. However, this oversized tank takes up a significant amount of space, making it impractical in chip factories. Therefore, technological innovation is needed. Utility Model Content

[0029] like Figure 1 As shown, the utility model provides a water ring vacuum pump system, which includes a water ring vacuum pump 1, a water tank 2, a pump inlet pipe 3, a pump outlet pipe 4 and a water inlet pipe 5. The water ring vacuum pump 1 is provided with a cooling water inlet and a cooling water outlet; the water tank 2 is provided with a first connecting port, a second connecting port and an overflow port, and the height of the overflow port is higher than the height of the first connecting port and the second connecting port; one end of the pump inlet pipe 3 is connected to the cooling water inlet of the water ring vacuum pump 1, and the other end of the pump inlet pipe 3 is connected to the first connecting port of the water tank 2; one end of the pump outlet pipe 4 is connected to the cooling water outlet of the water ring vacuum pump 1, and the other end of the pump outlet pipe 4 is connected to the second connecting port of the water tank 2; the water inlet pipe 5 is connected to the pump inlet pipe 3.

[0030] The water inlet pipe 5 is connected to the above-mentioned pump inlet pipe 3, so that the cooling water first passes through the water ring vacuum pump 1, and then enters the water tank 2 from the cooling water outlet of the water ring vacuum pump 1 through the pump outlet pipe 4. Subsequently, the water in the water tank 2 can also enter the water ring vacuum pump 1 through the pump inlet pipe 3 for circulating cooling. In this process, the cooling water is circulated through the water ring vacuum pump 1 and the water tank 2 on the one hand, and is transported from the outside through the water inlet pipe 5 on the other hand. On the basis of saving water, the volume of the water tank 2 is reduced as much as possible, thereby reducing the occupied area of the overall system and achieving the purpose of miniaturization.

[0031] In some embodiments, the height of the first connection port on the water tank 2 is higher than that of the second connection port, so that water can enter from the top of the water tank 2 and exit from the bottom of the water tank 2 to enter the water ring vacuum pump 1, thereby maximizing the utilization of the space in the water tank 2. The overflow port is higher than both ports, so that overflow will only occur when the circulating water in the water tank 2 reaches its maximum.

[0032] It should be noted that since most of the cooling water relies on the self-circulation between the water ring vacuum pump 1 and the water tank 2, after the circulating cooling water reaches a higher temperature, the water inlet pipe 5 can be increased to make the water in the water tank 2 flow out from the overflow port to reduce the temperature of the circulating water. In order to monitor the temperature of the water in the water tank 2, such as Figure 1As shown, in some embodiments, a temperature sensor 6 is provided in the water tank 2, and the temperature sensor 6 is provided between the first connection port and the second connection port. Thus, after the cooling water enters from the first connection port, it will first pass through the temperature sensor 6 and then enter the second connection port, thereby enabling timely monitoring of the water temperature in the water tank 2. In some embodiments, a first switch valve 8, a normally open solenoid valve 9, and a flow meter 10 are provided on the water inlet pipe 5. On the one hand, the flow meter 10 can accurately measure the flow rate, thereby achieving precise water supply control; on the other hand, the normally open solenoid valve 9 is provided, and combined with the first switch valve 8, ensures that the water inlet pipe 5 is unobstructed during normal power-on use. In the event of an emergency power outage, the normally open solenoid valve 9 can block the water inlet pipe 5 to prevent further water inflow. It should be noted that the first switch valve 8 is also normally open and can only be controlled by the first switch valve 8 when it is closed for system maintenance or when the normally open solenoid valve 9 is unable to operate. The first switch valve 8 can be a manual valve.

[0033] In some embodiments, a second on-off valve 11 and a first pressure gauge 12 are provided on the pump inlet pipe 3. The first pressure gauge 12 can test the water pressure entering the water ring vacuum pump 1, and the second on-off valve 11 can control the on-off of the pump inlet pipe 3 when necessary. For example, the second on-off valve 11 is a manual valve.

[0034] like Figure 1 As shown, in some embodiments, the water tank 2 is further provided with a liquid level monitoring member 7 to monitor the liquid level in the water tank 2, thereby maintaining the water level in the water tank 2 at a desired level and preventing the water level from being too low. The form of the liquid level monitoring member 7 is not specifically limited and can be either external or internal.

[0035] like Figure 1 As shown, in some embodiments, the water ring vacuum pump system further includes an air inlet pipe 13, which is connected to the air inlet of the water ring vacuum pump 1, so that air is injected into the water ring vacuum pump 1 through the air inlet pipe 13, and a third switch valve 15, a one-way valve 14 and a second pressure gauge 16 are provided on the air inlet pipe 13, wherein the third switch valve 15 can control the on-off of the air inlet pipe 13, and the one-way valve 14 can allow the gas to flow into the water ring vacuum pump 1 in one direction to avoid reverse circulation of the gas; a second pressure gauge 16 is provided on the air inlet pipe 13, so that the vacuum degree can be tested to ensure the normal operation of the water ring vacuum pump 1.

[0036] like Figure 1 As shown, in some embodiments, the water ring vacuum pump system further includes an air outlet pipe 17, which is connected to the air outlet of the water ring vacuum pump 1, and a speed control valve 18 is provided on the air outlet pipe 17, so that the vacuum degree is adjusted by the speed control valve 18, and the cavitation phenomenon is controlled by adjusting the vacuum degree (causing low pressure to be generated locally in the fluid, air to be sucked in and form bubbles and cavities).

[0037] In some embodiments, the water ring vacuum pump system further includes a first drain pipe 19 and a second drain pipe 20. A waste liquid port is provided at the bottom of the water tank 2. The first drain pipe 19 is connected to the waste liquid port. A fourth switch valve 21 is provided on the first drain pipe 19. When the water in the water tank 2 needs to be replaced, the fourth switch valve 21 can be opened to quickly drain the water in the water tank 2 from the first drain pipe 19. For example, the fourth switch valve 21 is a manual valve. The second drain pipe 20 is connected to the drain port of the water ring vacuum pump 1, and the fourth switch valve 21 is also provided on the second drain pipe 20 to drain the water in the water ring vacuum pump 1 when the water ring vacuum pump 1 is not used for a long time.

[0038] like Figure 1 As shown, in some embodiments, the water ring vacuum pump system also includes a liquid receiving pan 22, the water ring vacuum pump 1 and the water tank 2 are arranged above the liquid receiving pan 22, and a leakage sensor 24 is provided in the liquid receiving pan 22, so that if the water ring vacuum pump 1 and the water tank 2 leak, it will be sensed by the leakage sensor 24, and the leakage sensor 24 can be connected to the control system or the alarm system to remind the operator. In addition, the overflow port of the water tank 2 is connected to an overflow pipe 23, and the port of the overflow pipe 23 can extend out of the liquid receiving pan 22 or be connected to an external water collection part to prevent the overflow water of the water tank 2 from directly entering the liquid receiving pan 22 through the overflow port, causing the leakage sensor 24 to misjudge. In order to facilitate the discharge of the leaked liquid in the liquid receiving pan 22, the liquid receiving pan 22 is also provided with a discharge port for discharge.

[0039] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
