Description

Technical Field

[0001] The utility model belongs to the technical field of impellers and relates to a corrosion-resistant impeller, in particular to a corrosion-resistant impeller. Background Art

[0002] The water pump impeller is an important component of the water pump. The main function of the water pump impeller is to convert the rotational energy of the motor or other power source into the kinetic energy of the fluid. Through the rotation of the impeller, the fluid obtains a certain speed and pressure, thereby completing the fluid transportation.

[0003] Most impellers on the current market do not have a protective structure. When the impeller is used in an environment with poor water quality, some larger objects mixed in the water flow will impact the impeller, causing the impeller to be easily damaged. The impeller needs to be inspected and repaired more frequently, or even replaced, which will increase the maintenance cost of the water pump and reduce the overall economic benefits of the equipment. Summary of the invention

[0004] The purpose of the utility model is to provide a corrosion-resistant impeller in view of the above-mentioned problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a corrosion-resistant impeller, characterized in that it includes a mounting rod and an impeller body arranged on the mounting rod, a protective shell is fixedly arranged on the mounting rod, a filter plate is arranged on one side of the protective shell, two symmetrical mounting blocks are fixedly arranged on the outer side of the filter plate, and two symmetrical connecting shells are fixedly arranged on the outer side of the protective shell.

[0006] In the above-mentioned corrosion-resistant impeller, a connecting rod is movably provided on the inner wall of the connecting shell, a control board is fixedly provided on the top of the connecting rod, and the control board is attached to the outer side of the protective shell.

[0007] In the above-mentioned corrosion-resistant impeller, a positioning block is fixedly provided at the bottom end of the connecting rod, a spring is fixedly provided between the positioning block and the connecting shell, and a limiting hole for use with the positioning block is provided on the mounting block.

[0008] In the above-mentioned corrosion-resistant impeller, a screw rod for installation is provided on the impeller body, and a mounting hole is provided on the mounting rod.

[0009] In the above-mentioned corrosion-resistant impeller, a corrosion-resistant coating layer is sprayed on the impeller body.

[0010] Compared with the prior art, the corrosion-resistant impeller is provided with a filter plate that is easy to disassemble and assemble, thereby reducing the damage to the impeller body caused by impurities in the water flow, reducing the frequency of inspection and maintenance of the impeller body, reducing the maintenance cost of the water pump, and improving the overall economic benefits of the equipment.
