Problems solved by technology

At present, the cooling of the mechanical seal of the fluorine-lined pump generally adopts two methods of external flushing cooling water and medium self-cooling. In actual use, the external cooling water affects environmental pollution, and the effect of medium self-cooling is not good, resulting in a short service life of the mechanical seal.

Embodiment Construction

[0009] It can be seen from the accompanying drawings that this kind of heat-resistant PTFE-lined pump mechanical seal cooling water device includes a pump cover 1, a mechanical seal gland 2 and a pump shaft 3, and the mechanical seal gland 2 is tightly connected to the pump cover 1. The pump A water-cooling cover 4 is fastened on the cover 1, and the water-cooling cover 4 is connected with the mechanical seal gland 2. The water-cooling cover 4 is provided with a water inlet 5 and a water outlet 6. The mechanical seal gland 2 is provided with a sealing groove 7, and a sealing ring 8 is arranged in the sealing groove 7. Sealing ring 8 can adopt O type ring. With this mechanical seal cooling water device, a closed inner cavity is formed between the pump cover 1, the mechanical seal gland 2, the water cooling cover 4, and the mechanical seal static ring 9. When the pump is running, the cooling water flows from the water inlet on the water cooling cover 4. 5 enters and is discharg...

Abstract

The heat resistant polytetrafluoroethylene lined sealing and water cooling unit for pumps mainly includes one pump cover, one sealing gland connected tightly to the pump cover, one pump shaft, and one water cooling cover on the pump cover. The water cooling cover is fitted to the sealing gland and provided with one water inlet and one water outlet. The sealing and water cooling unit in the said structure can lower the temperature effectively to improve the sealing and cooling effect of pump and increase the service life of pump.

Description

technical field [0001] The invention relates to a cooling water and a fluorine-lined high-temperature molding device, in particular to a high-temperature-resistant cooling water device lined with a PTFE pump machine seal. Background technique [0002] Fluorine-lined pumps are mainly used to transport corrosive solutions such as high-temperature acids and alkalis of various concentrations, and are widely used in chemical, pickling, pharmaceutical, smelting and other industries. During the high-speed operation of the pump shaft, high temperature is often generated, which reduces the lubrication and sealing effect of the pump. At present, the cooling of the mechanical seal of the fluorine-lined pump generally adopts two methods of external flushing cooling water and medium self-cooling. In actual use, the external cooling water affects environmental pollution, and the effect of medium self-cooling is not good, resulting in a short service life of the mechanical seal. Contents...
