Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a high-strength pump head for a water pump. Background Art

[0002] Water pumps are common equipment in industrial and agricultural production. For example, a large amount of water-soluble cutting fluid is required during the operation of machine tools to prevent the tools and workpieces from overheating and even being scrapped. The used water-soluble cutting fluid needs to be discharged in time through the water pump. This type of water pump mainly includes three structures: motor, pump head, and water inlet cover group. The pump head is in the center and connects the upper and lower parts. Whether it is stable itself has an important impact on whether the motor and water inlet cover group can continue to work stably. In order to improve production efficiency, a considerable number of manufacturers produce simple and rough pump heads. For example, they only include an upper plate and a lower plate for connecting the motor and the water inlet cover group, and a main body containing a liquid channel. Although the strength of the one-piece metal casting structure of the pump head can meet most usage requirements, the simple and rough design still leads to the risk of damage. Based on this situation, how to improve the strength of the pump head is becoming an increasingly urgent problem that relevant technical personnel need to solve. Utility Model Content

[0012] 3. The lower connecting hole provides a good structural foundation for the installation of the supporting mechanical seal. The matching mechanical seal cooperates with the baffle to effectively prevent the liquid entering through the water inlet cover group from entering the pump head, but maintains efficient transportation to the liquid channel, thereby effectively ensuring that the water pump using this pump head can work efficiently.
