Description

Technical Field

[0001] The utility model relates to the technical field of circulating cooling devices for mechanical shaft sealing mechanisms, in particular to a circulating cooling device for mechanical shaft sealing mechanisms. Background Art

[0002] At present, the shaft sealing mechanisms of common rotating machinery such as centrifugal pumps, compressors, and screw pumps are all mechanical sealing mechanisms. A large amount of heat will be generated during the rotation of the rotating shaft of the rotating machinery. If the shaft sealing mechanism is not cooled in time, the shaft sealing mechanism and other components of the rotating machinery will be damaged, affecting the normal operation of the equipment. Therefore, a mechanical shaft sealing mechanism circulating cooling device is needed.

[0003] According to the description in a circulating cooling device for a shaft sealing mechanism of a rotating machinery disclosed on the patent website (the authorization announcement number is: CN215633948 U), "The utility model discloses a circulating cooling device for a shaft sealing mechanism of a rotating machinery, which relates to the technical field of cooling devices. The circulating cooling device for the shaft sealing mechanism of a rotating machinery comprises a drain joint, a radiator, a water tank and a water inlet joint connected in sequence, the water inlet joint being used to connect the water inlet of the shaft sealing mechanism, and the drain joint being used to connect the drain outlet of the shaft sealing mechanism. When in use, the shaft sealing mechanism is connected via the drain joint and the water inlet joint. The shaft sealing mechanism is a shaft sealing mechanism of a rotating machinery such as a centrifugal pump, a compressor, and a screw pump. The cooling water in the water tank enters the shaft sealing mechanism via the water inlet, and then enters the radiator via the drain outlet. The cooling water is cooled by the radiator and then returns to the water tank. The cooling water circulation is powered by the rotating machinery, and circulating cooling is adopted to avoid the water outage affecting the normal operation of the rotating machinery, while also saving water resources."

[0004] In view of the above description, the applicant believes that the following problems exist: when the device is in use, the water inlet and the water inlet joint, as well as the drain outlet and the drain outlet are connected by a variable buckle assembly, and the variable buckle assembly includes a plurality of variable buckle joints with different interface sizes. The corresponding variable buckle joints are selected for connection according to the sizes of the water inlet and drain outlet of the shaft sealing mechanism, thereby enhancing the practicality of the shaft sealing mechanism circulating cooling device of the rotating machinery. The variable buckle joint is a cylindrical or conical cylindrical structure, and the inner and outer sides of the variable buckle joint are respectively provided with internal and external threads, and the variable buckle joint and the water inlet, the drain outlet, the water inlet joint, and the drain joint are all connected by threads. When the water inlet joint is connected to the inside of the variable buckle joint and the water inlet is connected to the outside of the variable buckle joint, the internal threads of the variable buckle joint are consistent, and the external threads of the variable buckle joint change with the size of the water inlet of different shaft sealing mechanisms. When the water inlet joint is connected to the outside of the variable buckle joint and the water inlet is connected to the inside of the variable buckle joint, the external threads of the variable buckle joint are consistent, and the internal threads of the variable buckle joint change with the size of the water inlet of different shaft sealing mechanisms. The device cannot filter the water entering the water storage tank. Since there may be impurities in the water, scale may form inside the device over a long period of time, thereby causing the device to fail to operate normally. Utility Model Content
