[0002] Machine seal water refers to the water used in the sealing system of mechanical equipment, especially for the shaft seal part of rotating equipment such as pumps and agitators. Machine seal water usually comes from the factory's circulating water system or fresh water supply system. The main purpose of machine seal water is to provide a sealing effect to prevent the medium from leaking into the external environment or external impurities from entering the equipment. At the same time, it plays a role in cooling and lubricating the seals to extend the service life of the seals.
[0003] The disadvantages of mechanical seal water include: it may affect the sealing effect or even damage the seals due to impurities or poor water quality after long-term use. In addition, if the sealing system is improperly designed or operated, it may cause leakage of mechanical seal water, causing environmental pollution or production safety hazards. In the application of certain special media, mechanical seal water may react with the medium to produce corrosive substances, aggravating the damage of the seals.

[0037] like Figure 1-2 As shown, a mechanical seal water recycling system includes a collecting tank 1, a circulating pump 2, a mechanical seal water inlet pipe 3, and a mechanical seal water outlet pipe 4; the mechanical seal water inlet pipe 3 is connected to the water inlet of the machine pump assembly 7, and the water outlet of the machine pump assembly 7 is connected to the mechanical seal water outlet pipe; the mechanical seal water outlet pipe is connected to the collecting tank 1, and the collecting tank 1 is connected to the mechanical seal water inlet pipe 3.

[0041] The machine seal water outlet pipe 4 is connected to the water outlet of the machine pump assembly 7 and the collection tank 1 to discharge the machine seal water after use of the machine pump assembly 7 back to the collection tank 1 .
[0042] Therefore, through the above-mentioned technical scheme, the machine seal water discharged from the machine pump assembly 7 is collected in the collecting tank 1, and the machine seal water is introduced into the machine pump assembly 7 through the circulating pump 2 to form a circulating machine seal, thereby realizing the recycling of the machine seal water, reducing the consumption of production water, and reducing the frequency of damage to the machine seal due to lack of water.

The cooling device 5 is used to cool the machine seal water in the collection tank 1 to ensure that the temperature of the machine seal water is maintained within a suitable range to avoid system failures caused by high temperature. Specifically, the cooling device 5 can be any one of a heat exchanger, a cooling water pipeline or a cooling water tower, and a suitable cooling method is selected according to actual needs. The heat exchanger achieves cooling through the principle of heat exchange; the cooling water pipeline is usually used in conjunction with a cooling water tower to cool down through circulating water flow; the cooling water tower directly uses the principle of air convection to reduce the water temperature.
[0044] Through the above technical solution, the cooling device 5 cools the collection tank 1 to ensure that the machine sealing water maintains a suitable temperature during the recycling process, avoiding overheating that causes system performance degradation or equipment damage.

[0054] As a preferred technical solution, the temperature of the sealing water in the collection tank 1 is 20-60° C. Specifically, the temperature of the sealing water in the collection tank 1 should be maintained in the range of 20-60° C. This temperature range not only ensures the stability and fluidity of the sealing water during the circulation process, but also avoids potential damage to the pump assembly 7 and the system due to excessively high or low temperature.

Check the flow meters on the mechanical seal water inlet pipe and the mechanical seal water outlet pipe to ensure that they are working properly. Check the liquid level gauge and thermometer on the collection tank to ensure that they can accurately reflect the liquid level and temperature of the mechanical seal water in the tank.
[0061] 3. Operation phase:
[0062] When the pump assembly is started, the sealing water flows into the pump assembly from the sealing water inlet pipe to provide the necessary sealing and cooling. The used sealing water flows back to the collection tank from the water outlet of the pump assembly through the sealing water outlet pipe. The circulation pump pumps the sealing water in the collection tank back into the sealing water inlet pipe to form a closed-loop circulation system.
[0063] The cooling device (such as a heat exchanger, cooling water pipeline or cooling water tower) cools the mechanical seal water in the collection tank to ensure that the water temperature is maintained within the appropriate range of 20-60°C.
[0064] The water supply pipe adds fresh water to the collection tank when necessary to maintain the water balance in the system.
[0065] 4. Monitoring and adjustment:
[0066] Real-time monitoring of the flow meter data on the mechanical seal water inlet and outlet pipes to ensure that the flow rate of the mechanical seal water is maintained at 1-2m 3 / h range.
[0067] Monitor the liquid level of the machine seal water in the collection tank through the liquid level gauge on the collection tank to ensure that it is within the safe operating range.
[0068] Monitor the temperature of the machine seal water in the collection tank with a thermometer and adjust it as needed to keep the water temperature in a suitable working range.
[0069] 5. Shutdown and maintenance:
[0070] When the pump assembly stops, the circulation pump can continue to run for a period of time to ensure that the remaining machine seal water in the system can be fully circulated and cooled. Regularly inspect and maintain the system, including cleaning the collection tank, replacing worn seals, and checking the connections between the pump and the pipeline.
[0071] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways.
