Description

Technical Field

[0001] This utility model relates to the field of air compressor equipment, and in particular to a water replenishment device for a water-lubricated air compressor. Background Technology

[0002] Water-lubricated air compressors are air compressors that use water as the compression, sealing, and cooling medium. Due to their advanced sealing and isolation technology, the compressed air is cleaner and can be completely oil-free, making them suitable for the pharmaceutical, food, and medical fields.

[0003] Air compressors typically have a water-air tank inside, which separates water and air and provides cooling. The water-air tank needs to be replenished with water to maintain operation, so it is usually connected to an external water source and uses a solenoid valve for automatic water replenishment. However, in current technology, the water-air tank usually only uses automatic water replenishment and does not have intelligent detection function. Furthermore, it is not suitable for replenishing water when the machine is first started or after a long period of standby, because the water level in the tank cannot be predicted. Automatic water replenishment is also not suitable if a component fails during the automatic water replenishment process. Therefore, it is necessary to install a water replenishment device that can simultaneously detect the water level for automatic water replenishment and allow for manual water replenishment. Utility Model Content

[0004] In view of the defects of the prior art, the technical problem to be solved by this utility model is to provide a water replenishment device that can automatically detect water level and replenish water, as well as manually replenish water, to supply water to the water tank.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] A water replenishment device for a water-lubricated air compressor includes a barrel housed inside the water-lubricated air compressor, a detection device on the outer wall of the barrel house capable of detecting the water level inside the barrel house, a water pipe provided on one side of the barrel house, a bypass pipe connected to the water pipe, water supply connectors provided on the water pipe and the bypass pipe, an automatic water replenishment device and a manual water replenishment device respectively provided on the water pipe and the bypass pipe, and the automatic water replenishment device being connected to the detection device.

[0007] Furthermore, in this utility model, the water supply connector is located at the front end of the water pipe, and the automatic water replenishment device is located on the water pipe and behind the water supply connector.

[0008] Furthermore, in this utility model, one end of the bypass pipe is connected to the water supply connector, and the other end is connected to the water pipe and located behind the automatic water replenishment device. The manual water replenishment device is located at the front end of the bypass pipe.

[0009] Furthermore, the water supply connector in this new invention is externally connected to a water source.

[0010] Furthermore, the detection device in this utility model includes a connecting rod float level switch and a data transmission module.

[0011] Furthermore, the automatic water replenishment device in this utility model is a solenoid valve, which is electrically connected to a connecting rod float level switch.

[0012] Furthermore, the manual water replenishment device in this invention is a ball valve.

[0013] In summary, the advantages of this utility model over the prior art are:

[0014] This invention, by incorporating a water pipe, an automatic water replenishment device, and a detection device, enables automatic water replenishment based on the water level inside the tank. The inclusion of a bypass pipe and a manual water replenishment device allows users to manually replenish water. This manual replenishment can be selectively used for initial water replenishment, after prolonged standby, or in case of component damage during the water replenishment process, making it more suitable for various working environments of the water tank.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 3The present invention preferably provides a water replenishment device for a water-lubricated air compressor, comprising a barrel 1 disposed within the water-lubricated air compressor, a detection device 2 on the outer wall of the barrel 1 capable of detecting the water level inside the barrel 1, a water pipe 3 disposed on one side of the barrel 1, a bypass pipe 4 connected to the water pipe 3, a water supply connector 5 disposed on the water pipe 3 and the bypass pipe 4, and an automatic water replenishment device 6 and a manual water replenishment device 7 respectively disposed on the water pipe 3 and the bypass pipe 4, the automatic water replenishment device 6 being connected to the detection device 2. The barrel is one part of the interior of the water-lubricated air compressor, used for water-air separation and cooling. Water can be replenished through the water pipe, and the automatic water replenishment device can be activated to automatically replenish water based on the detection result of the detection device. The bypass pipe is provided for supplying water when the manual water replenishment device is needed. The water supply connector is used to connect the water supply pipe and the bypass pipe. Specifically, the automatic water replenishment and manual water replenishment switching method is: the manual water replenishment device is closed when the automatic water replenishment device is activated. When manual water replenishment is needed, the automatic water replenishment device is turned off. Users can control the timing of water inflow by turning on the manual water replenishment device at any time. Water flowing in from the water supply connector will flow into the bypass pipe without passing through the automatic water replenishment device. The water will bypass the automatic water replenishment device and enter the water pipe, and finally flow into the tank, completing the manual water replenishment.

[0020] In this invention, the water supply connector 5 is located at the front end of the water pipe 3, and the automatic water replenishment device 6 is located on the water pipe 3 and behind the water supply connector 5. This technical solution designates one side of the water pipe as the front side and the other side of the tank as the rear side. The automatic water replenishment device is located behind the water supply connector, allowing it to activate when the detection device detects a low water level. Water enters the water pipe under pressure, passes through the automatic water replenishment device, and finally flows into the tank.

[0021] In this invention, the bypass pipe 4 is connected to the water supply connector 5 at one end and to the water pipe 3 at the other end, located behind the automatic water replenishment device 6. The manual water replenishment device 7 is located at the front end of the bypass pipe 4. The bypass pipe is set around the automatic water replenishment device at both ends and is used for manual water replenishment. When the manual water replenishment device is turned on, the automatic water replenishment device needs to be turned off. The user can achieve water replenishment at any time by controlling the start time of the manual water replenishment device.

[0022] The water supply connector 5 described in this utility model is connected to an external water source. The water supply connector has only one external water source connection, while the water pipe and bypass pipe are both connected to the water supply connector. Therefore, when the water source is turned on, water will enter from whichever end is activated, whether it is the automatic water replenishment device or the manual water replenishment device.

[0023] The detection device 2 described in this utility model includes a linkage float level switch 21 and a data transmission module 22. The linkage float level switch is existing technology. Typically, a single or multiple reed switches are installed inside a sealed non-magnetic metal or plastic tube as needed. A hollow float containing an internal annular magnet is fixed to the relevant position of the reed switch within the rod diameter, allowing the float to float up and down within a certain range. The magnet inside the float attracts the reed switch to close, generating a switching action to control the liquid level. Normally open and normally closed represent the states when no liquid is injected. The linkage float level switch is a custom-made product; the appropriate float size is selected based on the temperature, pressure, specific gravity, acid and alkali resistance, etc., of the liquid being measured. When purchasing, the connection specifications (flange installation or threaded installation, etc.), the position of each actuation point, the actuation form (normally open or normally closed), and the total length must also be determined. The data transmission module is also existing technology, using a microcontroller or similar method to transmit signals to the automatic water replenishment device wirelessly or via wired connection.

[0024] The automatic water replenishment device 6 described in this invention is a solenoid valve, which is electrically connected to a connecting rod float level switch 21. The solenoid valve is existing technology and can be opened or closed by induction. It is connected to a detection device, allowing the detection device to control the opening and closing of the solenoid valve.

[0025] The manual water replenishment device 7 described in this invention is a ball valve. Ball valves are existing technology and can be manually opened and closed to control the timing of water entry.

[0026] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
