Description

Technical Field

[0001] This utility model relates to the field of water-air control systems, specifically a water-air control system with a diaphragm-type pumping mechanism. Background Technology

[0002] In automated production equipment, especially in the cooling systems of welding equipment, it is often necessary to connect and disconnect cooling water pipes. Traditionally, this process results in leakage of residual cooling water during pipe installation and disassembly. This leakage not only contaminates equipment and the environment but also wastes cooling water. Therefore, the industry needs a control system that can solve the leakage problem during the installation and disassembly of cooling water pipes. Utility Model Content

[0003] The present invention aims to solve the problem in the prior art that when automated equipment (such as welding cooling equipment) is disassembled and reassembled, residual cooling water in the pipeline leaks, leading to environmental pollution and water waste.

[0004] To solve the above-mentioned technical problems, this utility model provides a water-air control system with a diaphragm pump. The system includes a diaphragm pump, an inlet pipe, and a return pipe, all of which are fixed on a profile frame.

[0005] The water inlet pipe is arranged from top to bottom as follows: a main water inlet, a first diaphragm pump water inlet, and a robot water inlet. A water inlet solenoid valve is installed between the first diaphragm pump water inlet and the robot water inlet.

[0006] The return water pipeline is arranged from top to bottom as follows: main return water inlet, diaphragm pump outlet, second diaphragm pump inlet, and robot return water inlet. A return water check valve is installed between the diaphragm pump outlet and the second diaphragm pump inlet.

[0007] The robot's water inlet, water outlet, and cooling pipes together form the robot's cooling circulation water circuit.

[0008] The diaphragm pump is equipped with a pump body inlet pipe, which has a first pump body inlet and a second pump body inlet. The first pump body inlet is connected to the inlet of the first diaphragm pump, and the second pump body inlet is connected to the inlet of the second diaphragm pump.

[0009] Preferably, a filter screen is provided inside the water inlet pipe of the pump body.

[0010] Preferably, a water inlet solenoid valve is provided between the first water inlet and the second water inlet of the pump body on the water inlet pipe of the pump body.

[0011] This system utilizes a pneumatic diaphragm pump to generate a continuous negative pressure suction effect in the water circuit, enabling the automated equipment that uses water at the downstream end to have a cooling water back-pull function, thus ensuring that not a drop of water leaks when disassembling and assembling the water circuit of the welding cooling equipment.

[0012] Compared with the prior art, the present invention has the following significant advantages: 1. Achieve leak-proof backflow function: The system's pneumatic diaphragm pump can provide a continuous negative pressure suction effect, simultaneously suctioning the inlet and outlet water pipes to completely pump back the residual cooling water in the pipes, solving the technical problem of cooling water leakage during the disassembly and assembly of water circuits.

[0013] 2. Environmentally friendly and economical: It avoids pollution to equipment and the environment caused by cooling water dripping, while saving cooling water resources.

[0014] 3. Water and air isolation: The diaphragm pump adopts a diaphragm structure, which can effectively prevent cross-flow between the compressed air circuit and the cooling water circuit, ensuring the reliability of the system operation. Attached Figure Description

[0018] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0019] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1 This utility model provides a water-air control system with a diaphragm-type pumping mechanism. The following is a detailed description of this utility model in conjunction with the accompanying drawings and claims.

[0021] This system is mainly used for automated equipment such as welding cooling systems. Its core function lies in the cooling water return function achieved by the diaphragm pump 3. The entire system is integrated onto a robust profile frame 4, resulting in a compact structure. The system mainly consists of an inlet water pipe 1, a return water pipe 2, and the diaphragm pump 3.

[0022] The water inlet pipeline 1 is arranged from top to bottom as follows: main water inlet 11, first diaphragm pump water inlet 12, water inlet solenoid valve 13, and robot water inlet 14. Among them, the main water inlet 11 is responsible for connecting to the main water supply pipe of external cooling water, and the robot water inlet 14 is connected to the robot cooling circulation water circuit.

[0023] The return water pipeline 2 is arranged from top to bottom as follows: main return water inlet 21, diaphragm pump outlet 22, return water check valve 23, second diaphragm pump inlet 24, and robot return water inlet 25. Among them, robot return water inlet 25 is connected to the return water end of the robot cooling circulation water circuit.

[0024] The diaphragm pump 3 is equipped with a pump body inlet pipe 31, which has a first pump body inlet 32 ​​and a second pump body inlet 33. The first pump body inlet 32 ​​is connected to the first diaphragm pump inlet 12 via a connecting pipe. The second pump body inlet 33 is connected to the second diaphragm pump inlet 24 via a connecting pipe.

[0025] The diaphragm pump 3 is connected to the air circuit system through its air inlet, and uses compressed air as power to drive the diaphragm to work.

[0026] Working principle and key components: During normal operation (water supply), cooling water enters through the main inlet 11, flows through the inlet solenoid valve 13, and then enters the robot cooling circulation water circuit through the robot inlet 14. Water flows back through the robot return inlet 25 of the robot cooling circulation water circuit, passes through the return check valve 23 and the diaphragm pump outlet 22, and finally flows out through the main return inlet 21 to complete the circulation. At this time, the diaphragm pump 3 can be in standby or low-speed operation mode.

[0027] Back-pull function (to solve dripping): When it is necessary to disassemble or assemble the robot's cooling circulating water circuit or any connecting pipeline, the negative pressure suction function of diaphragm pump 3 is activated.

[0028] The first inlet 32 ​​and the second inlet 33 of the diaphragm pump 3 are respectively connected to the inlet and return water pipelines 2 (through the first diaphragm pump inlet 12 and the second diaphragm pump inlet 24).

[0029] The continuous negative pressure generated by the diaphragm pump 3 is applied to the entire robot cooling circulation water circuit and connecting pipes through the connection point. Before disassembly and assembly, this negative pressure forcefully draws the residual cooling water in the pipes back to the diaphragm pump 3, and discharges or recovers it to the storage tank (not shown) through the discharge end of the diaphragm pump 3, thereby ensuring that the pipe interface is leak-free when disconnected.

[0030] The inlet solenoid valve 13 is used to precisely control the opening, closing, and flow direction of the cooling water. The return water check valve 23 is installed on the return water pipe 2 to prevent backflow, especially when the diaphragm pump 3 is performing a backflow operation, to help isolate the water flow in the return water pipe 2.

[0031] To further improve the stability of the system, a filter screen 34 is also provided. The filter screen 34 is preferably located inside the pump body inlet pipe 31 (or at the inlet 12 of the first diaphragm pump / the inlet 24 of the second diaphragm pump) to filter large particulate impurities, protect the diaphragm and fluid channels, and prevent poor sealing and malfunction caused by impurities.

[0032] The diaphragm pump 3 utilizes its diaphragm structure to completely isolate the air path from the water path, preventing air and water from mixing.

[0033] Furthermore, the water inlet solenoid valve 35 is installed on the water inlet pipe 31 of the pump body to precisely control the path of water flow into the diaphragm pump 3, so as to achieve more precise backflow control or isolation.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
