Description

Technical Field

[0001] The utility model relates to the field of water pumps, in particular to a water pump anti-dry-running protection structure. Background Art

[0002] A water pump is a very practical mechanical device. Its main function is to transport liquid or increase the pressure of liquid. You can imagine a water pump as a power device that can push water flow or generate pressure on water flow; the working principle of a water pump is to transfer the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. According to different working principles, water pumps can be divided into types such as volumetric pumps and vane pumps. Volumetric pumps use the periodic change of the working chamber volume to transport liquid, while vane pumps use the interaction between the blades and the liquid to transport liquid.

[0003] Nowadays, when absorbing and discharging liquid, the water pump fails to be shut down in time due to negligence of the staff. Since there is no liquid inside the water pump, the water pump runs idle, causing the internal blades to rub for a long time and cause damage, which not only affects the work efficiency but also reduces the service life of the water pump. Even when the water pump is turned off, due to inertia, the blades cannot stop in time and there is no liquid delivery, and it still runs idle for a few circles. Utility Model Content
