Description

Technical Field

[0001] This utility model belongs to the field of water pumps, and relates to a water pump, and more particularly to a pipe-protected water pump. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals.

[0003] The pump body has an inlet pipe and an outlet pipe, which are used to connect to the water pipe and guide the water flow in and out. However, the inlet and outlet pipes are exposed and are easily damaged by accidental bumps, resulting in water leakage. This leads to a drop in water pressure inside the pump body and reduces the pump's head. In addition, the inlet and outlet pipes of the pump are mostly integrally formed with the pump body, making the pump body unusable.

[0004] For example, the easy-to-clean water pump with application number 201720076238.1 includes a water pump body and a water pump cleaning mechanism. The water pump body is a volute, with an inlet and an outlet at both ends. An impeller is installed inside the volute. An inlet valve is provided at the inlet, and an outlet valve is provided at the outlet. A liquid adding system is provided next to the inlet valve, and a liquid outlet valve is provided at the outlet valve.

[0005] The aforementioned patent involves filling the volute with water and then sealing it. Detergent is added through a liquid addition system, and the impeller is activated to agitate the water flow for washing. Finally, wastewater is discharged through a liquid discharge system. However, the inlet and outlet pipes lack protection and are easily damaged by impacts, leading to reduced pump body sealing. Utility Model Content

[0010] In the aforementioned pipe-protected water pump, a groove is provided at the through hole, a screw hole is provided inside the guide rod, and countersunk bolts are installed in the groove and the screw hole.

[0011] In the aforementioned pipe-protected water pump, a second buffer pad is installed on the surface of the buffer sheet, and a magnet is installed inside the second buffer pad.

[0012] In the aforementioned pipe-type water pump, a flange is provided on the base shell, and a connecting part is provided on the inlet pipe and the outlet pipe, with a sealing ring provided inside the connecting part.

[0013] Compared with the prior art, the advantages of this utility model are as follows: by setting a base shell outside the water inlet pipe and the water outlet pipe and setting a buffer pad on it to protect them from damage; the buffer pad is used to prevent small flying objects from passing through the buffer pad and hitting the base shell, causing damage to the base shell, and thus affecting the water inlet pipe and the water outlet pipe; the buffer pad protects the water inlet pipe and the water outlet pipe through the guide rod, guide cylinder, spring and buffer pad, preventing the water inlet pipe and the water outlet pipe from being accidentally damaged.
