Description

Technical Field

[0001] The utility model relates to the technical field of air compression equipment, in particular to a cooling water supply control system with multiple water pumps switched for compressed air preparation. Background Art

[0002] Air compressors play an extremely important role in industrial production. They prepare various gases by compressing air to provide power for production. However, air compressors will generate a lot of heat during operation due to mechanical friction and energy conversion. If the heat cannot be effectively dissipated, it is easy to cause the equipment to overheat and affect normal operation. The cooling system of the air compressor is particularly important. The most important part of the cooling system is the cooling water process, which provides heat dissipation and cooling functions for the air compressor. The cooling water process mainly includes two parts: the cooling water circulation system and the cooling water piping system. The cooling water circulation system includes components such as water pumps, coolers, water tanks and pipelines. The water pump plays the role of conveying circulating water, extracting circulating water from the water tank and sending it to the cooler. The cooler is a device that dissipates the heat and cools the hot water passing through the heat exchange surface. Usually, a water-cooled cooler or an air-cooled cooler is used. The cooling water in the cooler becomes warmer after heat exchange, and then returns to the water tank through the water pump for recirculation. In this way, the entire cooling water circulation system can continuously take away the heat generated by the air compressor, thereby ensuring that the air compressor maintains a stable operating temperature. The circulation process is mainly completed through the circulation piping system.

[0003] The cooling water piping system in the prior art is mainly responsible for connecting the cooling water together to achieve the purpose of circulating flow. These pipes are usually divided into two parts: an inlet pipe and an outlet pipe. The inlet pipe is connected between the water pump and the cooler to transport the cooling water from the water tank to the cooler. The outlet pipe is connected between the cooler and the water tank to send the cooled water back to the water tank again.

[0004] The above prior art has obvious beneficial effects, but still has shortcomings:

[0005] In the above-mentioned prior art, the circulation control of cooling water is formed by the pipeline system and the water pump connection. If the inlet and outlet pipes are blocked or a single water pump is damaged during the circulation control process, the overall circulation stability will be affected, and the smooth delivery of cooling water cannot be guaranteed, resulting in pipeline blockage, which in turn affects the cooling effect. For this reason, a cooling water supply control system with multiple water pumps switching for compressed air preparation is proposed. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides a cooling water supply control system with multiple water pumps for compressed air preparation. By installing corresponding switching supply pipelines on both the water inlet pipe and the water outlet pipe, flexible adjustment of the cooling water distribution process can be achieved, thereby minimizing the blockage and flow instability phenomenon in the cooling water distribution process and maintaining the stability of the cooling cycle process in the air compression preparation operation.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling water supply control system with multiple water pumps for compressed air preparation, comprising a main frame, one side of the main frame is connected to a connecting ring, and one side of the connecting ring is connected to a switching supply pipeline, the switching supply pipeline comprises a transmission and distribution pipeline, and both ends of the transmission and distribution pipeline are connected to connecting rings, one end of the connecting ring is connected to a pressure sensor, and a buzzer is provided on one side of the pressure sensor, the bottom end of the connecting ring is connected to a controller module, the middle end of the transmission and distribution pipeline is provided with a main water pump, and crossing pipelines are distributed on both sides of the transmission and distribution pipeline, and the middle end of the crossing pipeline is connected to an auxiliary water pump.

[0008] Preferably, the crossing pipelines are symmetrically cross-distributed along both sides of the transmission and distribution pipelines, and both ends of the crossing pipelines are connected to both ends of the transmission and distribution pipelines.

[0009] Preferably, the main water pump and the auxiliary water pump are electrically connected to the pressure sensor, and the middle ends of the transmission and distribution pipelines and the crossing pipelines are connected to the corresponding main water pumps and auxiliary water pumps.

[0010] Preferably, the main frame includes a water tank, and a water inlet pipe is connected to one side of the water tank, one end of the water inlet pipe is connected to a radiator, and the bottom end of the radiator is connected to a water outlet pipe.

[0011] Preferably, both ends of the water outlet pipe and the water inlet pipe are connected to the water tank and the radiator, and the water outlet pipe and the water inlet pipe are symmetrically distributed.

[0012] Preferably, the connecting ring comprises a ring tube, and a water hole is provided in the middle of the ring tube, thread grooves are provided at both ends of the water hole, and a rubber ring is attached to the inner wall of one side of the thread groove.

[0013] Preferably, the thread grooves are symmetrically opened along both ends of the ring tube, and the rubber ring is tightly fitted to one side of the thread groove.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model detects the internal pressure of the pipeline through a pressure sensor. When it exceeds the threshold, it cooperates with the controller module to control the connected auxiliary water pump to start the cross-pipeline for auxiliary distribution. At the same time, the buzzer operates to alert personnel to carry out maintenance. The cross-pipeline and auxiliary water pump connected on both sides of the distribution pipeline form a multi-line selection for the distribution process, avoiding the phenomenon of damage to a single water pump on a certain distribution line, providing multi-channel selectivity, and maintaining the stability of the cooling water inlet and outlet discharge process through the controller module. The flexibility of control switching is maintained, safety hazards are reduced, and a stable cooling effect is provided for the air compression preparation process.

[0016] 2. The cooling water of this control system is discharged through the water tank and the connected water inlet pipe, and the switching supply pipeline installed in the middle of the water inlet pipe transports the cooling water to the radiator module at the other end. At this time, the cooling water after heat dissipation absorbs the residual heat to form warm water, and is transported back to the water tank through the water outlet pipe at the bottom to form a stable circulation cooling process.

[0017] 3. This connecting ring uses the ring tube as the main structure. The two ends of the ring tube can be connected with the two ends of the switching supply pipeline through the threaded grooves to maintain the connection between the overall system and the switching supply pipeline. The rubber ring fitted to the inner wall can maintain the stable air tightness of the connection, and it is convenient for the disassembly and maintenance of the pipeline to improve convenience.

[0018] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model.

[0026] like Figure 1-3 As shown, the main frame 1 in the utility model is similar to the existing cooling water pipeline system structure. The main improvement of the utility model is that the corresponding switching supply pipelines 3 are installed in the water inlet pipe 102 and the water outlet pipe 104 to achieve flexible adjustment of the cooling water distribution process, thereby minimizing the blockage flow instability phenomenon in the cooling water distribution process and maintaining the stability of the cooling cycle process in the air compression preparation operation; the cooling water of the utility model is discharged through the water tank 101 and the connected water inlet pipe 102, and the switching supply pipeline 3 installed in the middle of the water inlet pipe 102 transports the cooling water to the radiator module at the other end. At this time, the cooling water after heat dissipation absorbs the residual heat to form warm water, and is transported back to the water tank 101 through the water outlet pipe 104 at the bottom to form a stable circulation cooling process.

[0027] like Figure 2As shown, the connecting ring 2 includes a ring tube 201, and a water hole 202 is provided in the middle of the ring tube 201, threaded grooves 203 are provided at both ends of the water hole 202, and a rubber ring 204 is attached to the inner wall of one side of the threaded groove 203. This connecting ring 2 uses the ring tube 201 as the main structure, and the two ends of the ring tube 201 can be connected to the two ends of the switching supply pipeline 3 through the threaded groove 203 to maintain the connection between the overall system and the switching supply pipeline 3, and the rubber ring 204 attached to the inner wall maintains the stable air tightness of the connection, and facilitates the disassembly and maintenance of the pipeline structure, thereby improving convenience.
