[0043] Example:

[0044] This embodiment provides a constant pressure water supply device for an air compressor, which is used to solve the technical problem of unstable water pressure of cooling water in air compressors in the prior art. The constant pressure water supply device for an air compressor includes a water pump 1, a pipe 2, a pressure sensor 3, and a control unit 4, wherein:

[0045] There are two water pumps 1, namely a first water pump 11 and a second water pump 12. One end of the first water pump 11 and the second water pump 12 is connected to a water source, and the other end is connected to an air compressor. The water pump 1 is used to provide high-pressure cooling water.

[0046] The pipeline 2 is used to connect the first water pump 11, the second water pump 12 and the air compressor. The arrangement of the pipeline 2 facilitates the delivery of high-pressure cooling water.

[0047] The pressure sensor 3 is installed on the pipeline 2. The pressure sensor 3 is used to detect the water pressure in the pipeline 2. In this way, the arrangement of the pressure sensor 3 facilitates monitoring of changes in the water pressure in the pipeline 2.

[0048] The control component 4 is installed on the pipeline 2 and is electrically connected to the pressure sensor 3 . The control component 4 is used to control the on and off of the first water pump 11 and the second water pump 12 .

[0049] The second water pump 12 has two states: state 1 and state 2.

[0050] State 1: when the first water pump 11 is connected, the second water pump 12 is disconnected;

[0051] In state two, when the first water pump 11 is disconnected, the second water pump 12 is in a connected state. In this way, through the setting of the control component 4 electrically connected to the pressure sensor 3, when the pressure sensor 3 detects insufficient pressure in the pipeline 2, it is convenient to control the working water pump 1 through the control component 4 to stop working, and at the same time connect the other water pump 1 to start working, and continue to provide high-pressure cooling water for the air compressor.

[0052] Through the above structure, when using the constant-pressure water supply device for an air compressor provided by the utility model, any one of the two water pumps 1 is connected through the control component 4 to start working, providing high-pressure cooling water for the air compressor, and the other water pump 1 is in a disconnected state. At the same time, the water pressure in the pipeline 2 is monitored by the pressure sensor 3. When the pressure sensor 3 detects that the pressure in the pipeline 2 is insufficient, the working water pump 1 is disconnected again through the control component, and the other water pump 1 is connected to start working to continue providing high-pressure cooling water for the air compressor. In this way, constant-pressure water supply is achieved by setting up two cross-working water pumps 1, and only one of the two water pumps 1 is always in a working state, saving energy. Therefore, through the cooperation of the two water pumps 1, the pressure sensor 3 and the control component 4, when the pressure of one of the water pumps 1 is insufficient, the other water pump 1 is driven to start working to continue providing high-pressure cooling water for the air compressor, so that the constant-pressure water supply device for an air compressor provided by the utility model can provide cooling water with stable water pressure, thereby reducing the probability of shutdown of the water-cooled unit due to overheating.

[0053] An optional implementation of this embodiment is as follows: the pipeline 2 includes a main pipeline 21, a first pipeline 22 and a second pipeline 23, wherein:

[0054] One end of the main pipe 21 is connected to the air compressor.

[0055] One end of the first pipe 22 is connected to the first water pump 11 , and the other end is communicated with the other end of the main pipe 21 .

[0056] One end of the second pipe 23 is connected to the second water pump 12, and the other end is connected to the other end of the main pipe 21. Optionally, the main pipe 21, the first pipe 22 and the second pipe 23 are connected through a three-way joint. By connecting the first water pump 11 and the second water pump 12 in parallel, it is easier to control the on and off of the first water pump 11 and the second water pump 12.

[0057] An optional implementation of this embodiment is as follows: the control element 4 includes a first electrically controlled valve 41 and a second electrically controlled valve 42, wherein:

[0058] The first electrically controlled valve 41 is installed on the first pipeline 22 and is used to control the on / off of the first water pump 11 . The setting of the first electrically controlled valve 41 makes it easier to control the on / off of the first water pump 11 .

[0059] The second electrically controlled valve 42 is installed on the second pipe 23 and is used to control the on and off of the second water pump 12. The setting of the second electrically controlled valve 42 makes it easier to control the on and off of the second water pump 12. The switching speed of the electric valve can be adjusted, and the structure is simple and easy to maintain.

[0060] An optional implementation of this embodiment is as follows: it also includes a pressure gauge 5 installed on the main pipeline 21. The pressure gauge 5 is used to detect the water pressure in the main pipeline 21. This makes it easy for staff to observe whether the water pressure in the pipeline 2 is in a normal state.

[0061] An optional implementation of this embodiment is as follows: it also includes two check valves 6, namely a first check valve 61 and a second check valve 62. The first check valve 61 is installed on the first pipe 22, and the first check valve 61 is used to prevent the liquid in the first pipe 22 from flowing back. The second check valve 62 is installed on the second pipe 23, and the second check valve 62 is used to prevent the liquid in the second pipe 23 from flowing back. In this way, by setting the first check valve 61 and the second check valve 62, the first water pump 11 and the second water pump 12 are protected to prevent pressure leakage.

[0062] Optionally, the first check valve 61 and the second check valve 62 are both connected to the first pipe 22 and the second pipe 23 through flanges. In this way, the first check valve 61 and the second check valve 62 connected through flanges are easier to replace and maintain.

[0063] An optional implementation of this embodiment is as follows: it also includes two protective covers 7, and the two protective covers 7 are respectively installed on the first water pump 11 and the second water pump 12. In this way, through the provision of the protective covers 7, the first water pump 11 and the second water pump 12 are protected, the probability of the first water pump 11 and the second water pump 12 being wetted by rain and rusted is reduced, and the service life of the first water pump 11 and the second water pump 12 is extended.

[0064] Optionally, the protective cover 7 includes a protective plate 71 and a connecting rod 72:

[0065] The protection plate 71 is located above the water pump 1 and is a plate structure.

[0066] Optionally, the longitudinal section of the protective plate 71 is arc-shaped, and the axis of the protective plate 71 is arranged parallel to the axis of the water pump 1. The arc-shaped protective plate 71 is more in line with the shape of the water pump 1 and is more convenient for protecting the water pump 1.

[0067] One end of the connecting rod 72 is installed on one side of the protective plate 71, and the other end is installed on the water pump 1. In this way, through the setting of the connecting rod 72, not only can the protective plate 71 be fixed on the water pump 1, but also a gap is created between the protective plate 71 and the water pump 1, which facilitates heat dissipation of the water pump 1.

[0068] Optionally, there are multiple connecting rods 72, and both ends of the multiple connecting rods 72 are respectively installed on the water pump 1 and the protective plate 71. In this way, through the arrangement of multiple connecting rods 72, the connection between the water pump 1 and the protective plate 71 is made more secure.

[0069] Optionally, a lifting ring 8 is further included and installed on the side of the protective plate 71 away from the water pump 1. In this way, the provision of the lifting ring 8 makes it easier to lift the water pump 1, thereby making it easier to install the water pump 1.

[0070] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model.
