Description

Technical Field

[0001] This utility model is a process cooling water supply device, belonging to the field of process cooling water technology. Background Technology

[0002] In industrial production process cooling water supply systems, vertical pumps have become the mainstream conveying equipment due to their advantages of small footprint, convenient installation, and stable head. To ensure the continuity of cooling water supply and avoid production stoppages caused by single pump failures, two sets of vertical pumps are usually equipped on site and operate in an alternating mode. When one set of pumps is in operation, the other set is in standby mode, which facilitates maintenance personnel to carry out maintenance, repair, and replacement of vulnerable parts on the stopped pumps, thereby constructing a stable cooling water supply guarantee system.

[0003] In low-temperature environments, if cooling water remains in the impeller chamber of a standby vertical pump, it is highly susceptible to freezing due to the extremely low temperature. This can not only crack pump components but also cause the impeller to seize, affecting subsequent emergency restarts. Therefore, after the equipment is shut down, the residual water in the impeller chamber must be completely drained to eliminate the risk of freezing. However, draining the residual water can lead to new problems. When the vertical pump is restarted, its impeller chamber is empty, and the pump cannot quickly establish a stable negative pressure and liquid seal environment after startup. This results in a failure to pump cooling water without drawing it. In this case, it is necessary to disassemble the pipeline to add water to the impeller chamber of the vertical pump, which is a cumbersome operation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a process cooling water supply device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a process cooling water supply device, comprising: The vertical pump is provided in two sets. The outlet end of each set of vertical pumps is equipped with a first valve. A water delivery pipe is installed at the end of one of the first valves away from the vertical pump. A one-way valve is installed at the end of the water delivery pipe away from the first valve. The one-way valve is open in the direction away from the water delivery pipe. A connecting pipe is connected at the end of the first valve that is not directly connected to the water delivery pipe away from the vertical pump. One end of the connecting pipe is connected to the water delivery pipe. A water storage cylinder is equipped with a cylinder cover at the top. The one-way valve is connected to the water storage cylinder. A pipe joint is installed at the upper part of the outer surface of the water storage cylinder. A second valve is installed at the end of the connecting pipe away from the water supply pipe. The second valve is installed at the bottom of the water storage cylinder.

[0006] Furthermore, the vertical pump is provided with a main inlet pipe on one side. One end of the main inlet pipe is closed, and the open end of the main inlet pipe is connected to the process cooling water storage container. Two sets of third valves are installed on the outer surface of the main inlet pipe. A branch pipe is installed at the end of the third valve away from the main inlet pipe, and the end of the branch pipe away from the third valve is connected to the liquid inlet end of the vertical pump.

[0007] Furthermore, the end of the first valve away from the water supply pipe is connected to a bend via bolts, and the end of the bend away from the first valve is connected to the outlet end of the vertical pump.

[0008] Furthermore, a drain valve is installed on the outer surface of the bend, and the drain valve is located on the lower side of the horizontal part of the bend.

[0009] Furthermore, the lower end of the water storage cylinder is connected to a support arm via a connector. A twisted part is installed at the end of the support arm away from the water storage cylinder, and a positioning seat is installed at the end of the twisted part away from the support arm. Multiple fixing holes are provided on the upper surface of the positioning seat.

[0010] Furthermore, the connector includes a circular ring, the lower end of the water storage cylinder is fitted with the circular ring, one end of the support arm is connected and fixed to the circular ring, and both the upper and lower sides of the circular ring are provided with blocking rings, the blocking rings are in sliding contact with the circular rings, and the blocking rings are fitted on the water storage cylinder and connected and fixed to the water storage cylinder.

[0011] Furthermore, a first connecting pipe is installed at the bottom of the water storage tank, and the end of the second valve away from the connecting pipe is connected to the lower end of the first connecting pipe. A second connecting pipe is installed at the lower part of the outer surface of the water storage tank, and the end of the second connecting pipe away from the water storage tank is connected to the one-way valve by a bolt.

[0012] Furthermore, the vertical pump has a bottom frame on its lower side, and a support is installed on the upper surface of the bottom frame by multiple sets of brackets. The vertical pump is installed on the upper surface of the support by screws.

[0013] The beneficial effects of this utility model are: After the standby vertical pump empties the water from the impeller chamber, the second valve at the bottom of the water tank can be opened. The cooling water in the water tank will flow into the flow channel and impeller chamber of the vertical pump through the connecting pipe, completing the pre-filling of the pump body. This allows the pump to quickly form a liquid seal and negative pressure when it starts up, avoiding the failure of running dry without water. There is no need to manually disassemble the pipeline to add water, which greatly shortens the pump start-up preparation time and ensures the timely supply of cooling water.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a process cooling water supply device, including a vertical pump 1, two sets of vertical pump 1, each set of vertical pump 1 is equipped with a first valve 2 at the outlet end, a water delivery pipe 23 is installed at the end of the first valve 2 away from the vertical pump 1, and a one-way valve 24 is installed at the end of the water delivery pipe 23 away from the first valve 2. The one-way valve 24 is open in the direction away from the water delivery pipe 23. The one-way valve 24 at the end of the water delivery pipe 23 can prevent the cooling water in the water storage tank 5 from flowing back to the water delivery pipe 23, ensuring that the water storage tank 5 always retains a sufficient amount of cooling water, and providing a stable water source for the pre-filling liquid of the vertical pump 1.

[0017] See Figure 1 and Figure 2A first valve 2, not directly connected to the water supply pipe 23, has a connecting pipe 3 at its end furthest from the vertical pump 1. One end of the connecting pipe 3 is connected to the water supply pipe 23. A cylinder cover 52 is installed on the upper end of the water storage cylinder 5. A second connecting pipe 51 is installed on the lower part of the outer surface of the water storage cylinder 5. The end of the second connecting pipe 51 furthest from the water storage cylinder 5 is connected to a one-way valve 24 by bolts, thus connecting the one-way valve 24 to the water storage cylinder 5. A pipe joint 53 is installed on the upper part of the outer surface of the water storage cylinder 5. A second valve 31 is installed on the end of the connecting pipe 3 furthest from the water supply pipe 23. A first connecting pipe 32 is installed at the bottom of the water tank 5. The end of the second valve 31 away from the connecting pipe 3 is connected to the lower end of the first connecting pipe 32. After the standby vertical pump 1 drains the water from the impeller chamber, the second valve 31 at the bottom of the water tank 5 can be opened. The cooling water in the water tank 5 will flow into the flow channel and impeller chamber of the vertical pump 1 through the connecting pipe 3 to complete the pre-filling of the pump body. This allows the pump to quickly form a liquid seal and negative pressure when it starts up, avoiding the failure of running dry without water. There is no need to manually disassemble the pipes to add water, which greatly shortens the pump start-up preparation time and ensures the timely supply of cooling water.

[0018] See Figure 1 and Figure 2 A main inlet pipe 4 is provided on one side of the vertical pump 1. One end of the main inlet pipe 4 is closed, and the open end of the main inlet pipe 4 is connected to the process cooling water storage container. Two sets of third valves 41 are installed on the outer surface of the main inlet pipe 4. A branch pipe 42 is installed at the end of the third valve 41 away from the main inlet pipe 4. The end of the branch pipe 42 away from the third valve 41 is connected to the liquid inlet end of the vertical pump 1. A bend pipe 21 is bolted to the end of the first valve 2 away from the water supply pipe 23. The end of the bend pipe 21 away from the first valve 2 is connected to the liquid outlet end of the vertical pump 1. A drain valve 22 is installed on the outer surface of the bend pipe 21. The drain valve 22 is located on the lower side of the horizontal part of the bend pipe 21. The drain valve 22 on the bend pipe 21 can quickly drain the residual water in the impeller chamber and flow channel after the vertical pump 1 is stopped. To fundamentally eliminate the risk of freezing in low-temperature environments, prevent pump body components from freezing and cracking or impeller jamming, and ensure the integrity of standby pumps, two sets of vertical pumps 1 are connected to the main water inlet pipe 4 via branch pipes 42, enabling independent water intake and alternating operation; at the same time, the connecting pipe 3 connects the liquid outlet pipes of the two sets of pumps, and with the opening and closing control of the first valve 2, it can ensure stable water supply when a single pump is working, and when one pump is under maintenance, the other pump can provide water supply throughout the entire process through the connecting pipe 3 without interrupting the process cooling requirements. The bottom frame 13 is provided on the lower side of the vertical pump 1, and the support 11 is installed on the upper surface of the bottom frame 13 via multiple sets of brackets 12. The vertical pump 1 is installed on the upper surface of the support 11 with screws. The structure formed by the bottom frame 13, brackets 12 and support 11 together supports the two sets of vertical pumps 1.

[0019] See Figures 1-4A circular ring 6 is fitted around the lower end of the water storage cylinder 5. One end of the support arm 61 is connected and fixed to the circular ring 6. A blocking ring 62 is provided on both the upper and lower sides of the circular ring 6. The blocking ring 62 slides in contact with the circular ring 6. The blocking ring 62 is fitted onto the water storage cylinder 5 and is connected and fixed to the water storage cylinder 5. A twisted part 63 is installed at the end of the support arm 61 away from the water storage cylinder 5. A positioning seat 64 is installed at the end of the twisted part 63 away from the support arm 61. Multiple fixing holes are opened on the upper surface of the positioning seat 64. The blocking ring 62 restricts the relative position between the circular ring 6 and the water storage cylinder 5. The circular ring 6 is rotated around the water storage cylinder 5 according to the site environment until the positioning seat 64 moves to the required position. The positioning seat 64 is installed in the required position using the fixing holes to reinforce the water storage cylinder 5 and improve the stability of the structure.
