Description

Technical Field

[0001] This utility model relates to the field of circulating water pump technology, specifically a circulating water pump with a ceramic coating. Background Technology

[0002] Ceramic-coated circulating water pumps are typically used to enhance their wear resistance, corrosion resistance, and extend their service life. Ceramic coatings are usually achieved by applying ceramic material to the surfaces of key pump components, forming a hard protective layer that improves pump performance.

[0003] The existing patent with publication number CN221220829U proposes a circulating water pump, in which a connector fixed on the motor is set between the pump body and the motor. The pump body and the connector are hinged together, and the opposite ends of the connection are fixed by a snap-fit ​​component, which makes the connection and disassembly between the pump body and the motor more convenient.

[0004] However, the pump body and the inner walls of the second ring do not have a ceramic coating. With prolonged use, the metal pump body and the inner walls of the second ring will experience wear and rust. Utility Model Content

[0005] The purpose of this utility model is to provide a circulating water pump with a ceramic coating, so as to solve the problem that the inner walls of the pump body and the second ring body do not have a ceramic coating, and the inner walls of the metal pump body and the second ring body will wear and rust after long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circulating water pump with a ceramic coating, comprising a base plate, a motor fixedly mounted on one side of the upper end of the base plate, a drive shaft fixedly mounted on the output end of the motor, a first fixing plate fixedly mounted on one side of the motor, a first connecting member fixedly mounted on one side of the first fixing plate, a second connecting member mounted on one side of the first connecting member, an inlet pipe and an outlet pipe fixedly mounted on one side and the upper end of the second connecting member respectively, a drive blade fixedly mounted on the outer wall of the drive shaft, a ceramic coating fixedly mounted inside both the first and second connecting members, a first screw mounted on one side of the first connecting member, the output end of the first screw passing through one side of the second connecting member and having a nut threaded on its outer wall, and a sealing gasket fixedly mounted on the side of the second connecting member close to the first connecting member.

[0007] Preferably, a replacement structure is provided between the drive shaft and the drive blade. The replacement structure includes an assembly plate fixedly installed on the outer wall of the drive shaft, and two third screws fixedly installed on one side of the drive blade. The output end of the third screw passes through the assembly plate and a nut is fixedly installed on its outer wall.

[0008] Preferably, a sealing ring is fixedly provided on the side of the drive blade near the assembly plate.

[0009] Preferably, an external thread is fixedly provided on one side of the outer wall of the drive shaft, and a flow divider is provided on the thread of the outer wall of the drive shaft.

[0010] Preferably, a second screw is provided inside the first fixing plate, and the output end of the second screw passes through the first fixing plate and the other side of the first connector, and a nut is provided on the outer wall thread.

[0011] Preferably, a horizontal plate is fixedly installed on one side of the upper end of the base plate, and a first vertical plate is fixedly installed on one side of the upper end of the horizontal plate, with the upper end of the first vertical plate being inserted into the lower end of the outer wall of the water inlet pipe.

[0012] Preferably, a second vertical plate is fixedly provided on the other side of the upper end of the horizontal plate, and the upper end of the second vertical plate is inserted into the outer wall of the second connector.

[0013] Preferably, the outer wall of the outlet pipe is fixedly provided with a reinforcing member, and the lower protruding part of the reinforcing member is inserted into the upper end of the outer wall of the inlet pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) By fixing a ceramic coating on the inner walls of both the first connector and the second connector, the damage to the inner walls of the first connector and the second connector can be reduced when water flows through the inner walls of the first connector and the second connector. Moreover, since the inner walls of the two first connectors and the second connector are connected at both ends, the difficulty of covering the ceramic coating can be reduced during production.

[0016] 2) By setting up a replacement structure, when the drive blades are damaged or corroded by water impact over a long period of time, the drive blades can be replaced, ensuring the long-term use of the entire pump body. Attached Figure Description

An inlet pipe 8 and an outlet pipe 9 are fixedly mounted on one side and the upper end of the second connector 6, respectively. A drive blade 7 is fixedly mounted on the outer wall of the drive shaft 3. A ceramic coating is fixedly mounted inside both the first connector 5 and the second connector 6. A first screw 11 is mounted on one side of the first connector 5. The output end of the first screw 11 passes through one side of the second connector 6 and a nut is threaded on its outer wall. A sealing gasket 10 is fixedly mounted on the side of the second connector 6 near the first connector 5.

[0026] See Figure 1 , Figure 4 and Figure 5Furthermore, a sealing ring 16 is fixedly installed on the side of the drive blade 7 near the assembly plate 14, an external thread 18 is fixedly installed on the outer wall of the drive shaft 3, a flow divider 17 is installed on the outer wall thread of the drive shaft 3, a second screw 12 is installed inside the first fixed plate 4, the output end of the second screw 12 passes through the first fixed plate 4 and the other side of the first connector 5 and a nut is installed on the outer wall thread, a horizontal plate 19 is fixedly installed on the upper side of the bottom plate 1, a first vertical plate 20 is fixedly installed on the upper side of the horizontal plate 19, the upper end of the first vertical plate 20 is inserted into the lower end of the outer wall of the water inlet pipe 8, a second vertical plate 21 is fixedly installed on the other side of the upper end of the horizontal plate 19, the upper end of the second vertical plate 21 is inserted into the outer wall of the second connector 6, a reinforcing member 22 is fixedly installed on the outer wall of the water outlet pipe 9, and the lower protruding part of the reinforcing member 22 is inserted into the upper end of the outer wall of the water inlet pipe 8.

[0027] Specifically, the sealing ring 16 can ensure that the drive blade 7 fits and is fixed better with the assembly plate 14, the diverter 17 can divert the water source entering one side of the drive blade 7, and the horizontal plate 19 is used to set the first vertical plate 20 and the second vertical plate 21.

[0028] Example 2

[0029] See Figure 4 Furthermore, based on Embodiment 1, a replacement structure 13 is provided between the drive shaft 3 and the drive blade 7.
