Description

Technical Field

[0001] This utility model relates to the field of water pump skid integration technology, specifically to a skid-type water pump unit. Background Technology

[0002] Pump skid integration technology combines pipes, valves, pumps, containers, and instruments into a single functional and modular device within a structural frame. Therefore, pump skids involve overall skid design, layout planning, and manufacturing processes, requiring consideration of connection methods and spatial arrangement between components to achieve compact installation, convenient operation and maintenance, and improved system stability and reliability. In numerous industrial equipment systems, the use of pump skids in conjunction with cryogenic chillers can significantly improve overall operating efficiency. Cryogenic chillers require a stable and efficient water circulation system to ensure consistent cooling output. The integrated design of the pump skid allows for precise adjustment of key parameters such as water flow speed and pressure, ensuring a suitable water supply to the chiller during operation and preventing cooling fluctuations caused by unstable water flow, thereby improving the overall system efficiency.

[0003] However, some problems still exist in the existing technology, such as water system issues: because the system is not equipped with level gauges and level switches, when the system water level drops or an abnormal situation occurs where chilled water cannot be delivered to external equipment, although the automatic water replenishment valve will automatically activate to replenish water, it is difficult for staff to detect the water shortage in the system in a timely manner. This information lag may cause external equipment to overheat due to insufficient cooling, leading to equipment failure and unnecessary losses for the company. Another example is the layout of the dosing tank: given that the maximum external dimensions of the water pump skid are fixed, placing the dosing tank at the front will inevitably extend the pipeline length. The additional pipeline not only requires more pipe material costs but also brings higher installation costs, and also increases the later pipeline maintenance costs, significantly increasing the overall project cost and hindering the efficient use of resources and cost control. Utility Model Content

[0004] The main purpose of this utility model is to provide a skid-mounted water pump unit to overcome the problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A skid-mounted water pump unit includes a dosing tank, a buffer tank, a pressure regulating component, a water pump, and a float level switch. The float level switch is located inside the buffer tank and is used to detect the water level in the buffer tank. The dosing tank has a rear-mounted layout, and its output end is connected to the main pipe between the buffer tank and the water pump. The buffer tank is used to temporarily store and buffer the chilled water flowing into it.

[0007] Furthermore, the float level switch is located at 1 / 3 of the height of the buffer tank.

[0008] Furthermore, there are two water pumps, each connected to the main pipe.

[0009] Furthermore, the pressure regulating assembly includes an expansion tank, an automatic water supply valve, and a bypass valve. The expansion tank is used to buffer the system pressure within the water pump skid. The automatic water supply valve and the bypass valve are arranged side by side on the pipeline between the expansion tank and the system inlet.

[0010] Furthermore, when the system pressure inside the water pump skid decreases, the expansion tank releases water from its interior to replenish the system, and at the same time, the automatic water replenishment valve automatically opens to replenish water to the system and the expansion tank.

[0011] Furthermore, the bypass valve is manually opened to replenish water to the system and the expansion tank.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention features a float level switch installed at 1 / 3 of the buffer tank. When the water level in the buffer tank drops below 1 / 3, the float of the float level switch lowers and outputs a signal, which is connected to the front-end low-temperature chiller electrical box and activates the water replenishment signal and alarm, thereby achieving timely water replenishment and improving the stability of the water pump skid and the stability of the front and rear systems.

[0014] By placing the dosing tank at the rear and connecting it directly to the main pipe between the buffer tank and the water pump, the pipeline laying path is effectively shortened. This not only simplifies the system structure but also significantly reduces pipeline installation costs, achieving a dual improvement in economy and practicality. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] Combination Figures 1 to 2 This embodiment provides a skid-mounted water pump unit, including a dosing tank 1, a buffer tank 2, an expansion tank 3, an automatic water supply valve 4, a bypass valve 5, a water pump 6, and a float level switch 7. The float level switch 7 is located inside the buffer tank 2 and is used to detect the water level inside the buffer tank 2. The dosing tank 1 adopts a rear-mounted layout, and its output end is connected to the main pipe between the buffer tank 2 and the water pump. The buffer tank 2 is used to temporarily store and buffer the chilled water flowing into it.

[0020] In this embodiment, by placing the dosing tank 1 downstream and directly connecting it to the main pipe between the buffer tank 2 and the water pump 6, the pipeline laying path is effectively shortened. This improvement not only simplifies the system structure but also significantly reduces pipeline installation costs, achieving a dual improvement in economy and practicality.

[0021] In this embodiment, the float level switch 7 is located at 1 / 3 of the height of the buffer tank 2. When the water level in the buffer tank 2 drops below 1 / 3, the float lowers and outputs an (ON) signal, which is connected to the front-end low-temperature chiller electrical box and activates the water replenishment signal and alarm. This enables timely water replenishment and alerts the system that insufficient water level in the buffer tank will prevent pumping to downstream equipment requiring cooling, thus improving the stability of the pump skid and the overall stability of the front and rear systems.

[0022] Specifically, the float level switch 7 uses a low water level output signal method. When the float swings up and down along a fixed fulcrum or axis under the action of liquid buoyancy as the liquid level rises or falls, the magnet at the end of the float fixing rod swings under the action of the lever, thereby driving the micro switch in the junction box to operate and output an ON or OFF signal, thus providing alarm prompts or remote control.

[0023] In this embodiment, there are two water pumps 6, which are connected to the main pipe respectively.

[0024] In this embodiment, the pressure regulating component includes an expansion tank 3, an automatic water supply valve 4, and a bypass valve 5. The expansion tank 3 is used to buffer the system pressure inside the water pump skid. The automatic water supply valve 4 and the bypass valve 5 are arranged side by side on the pipeline between the expansion tank 3 and the system inlet.

[0025] In this embodiment, when the system pressure inside the pump skid decreases, the expansion tank 3 releases water from its interior to replenish the system, and simultaneously, the automatic water supply valve 4 automatically opens to replenish water to the system and the expansion tank 3. The bypass valve 5 is manually opened to replenish water to the system and the expansion tank 3.

[0026] The solution in this embodiment avoids the situation where, when the system lacks a level gauge and level switch, if the system water level drops or an abnormal situation occurs where chilled water cannot be delivered to external equipment, although the automatic water replenishment valve will automatically activate to replenish water, staff may not be able to detect the water shortage problem in a timely manner. This also prevents information delays that could lead to external equipment overheating due to insufficient cooling, resulting in equipment failure and hidden costs such as equipment maintenance and downtime for the company.

[0027] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
