[0003] Damage is difficult to predict due to uncontrollable engine water pump belt life
Once the tension of the water pump belt drops or is damaged or broken, the force driving the water pump pulley 11 will drop, and the water pump pulley will drop (or be zero) when the water pump pulley turns 11 speeds, causing the ability of the water pump to pump water to drop, which in turn will cause the flow rate of the coolant to drop (or is zero), causing the engine to fail due to poor cooling

Embodiment Construction
[0014] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0015] Such as Figure 2 to Figure 4 As shown, the specific structure of the engine water pump according to the specific embodiment of the present invention includes: a water pump body and a pressure sensor 28 for monitoring the water pump pressure at the water pump high pressure cavity of the water pump body, wherein the water pump body does not change the main structure of the original water pump and pump function. The water pump high pressure chamber of the water pump body is provided with a pressure sampling hole for the pressure sensor 28 to monitor the pressure of the water pump high pressure chamber in real time. Like this, by using the corresponding relationship between the water pump flow and its pressure, it ...

The invention discloses an engine water pump. The engine water pump comprises a water pump body and a pressure sensor, a water pump belt wheel and a water pump shaft are coaxially arranged, the waterpump shaft is arranged in a water pump shell, under drive of the water pump belt wheel, the water pump shaft drives an impeller to rotate, a water pump high-pressure cavity is formed in the water pumpshell, a pressure sampling hole is formed in the position, corresponding to the water pump high-pressure cavity, of the water pump shell, the pressure sensor is directly arranged on the pressure sampling hole or connected with the pressure sampling hole through a guide pressure pipe, and cooling liquid pressure in the water pump high-pressure cavity is sampled. According to the engine water pump,on the basis of not changing original main structures and water pumping functions of the water pump, the pressure sensor for monitoring the water pump pressure is additionally arranged on the water pump high-pressure cavity, the pressure of the water pump high-pressure cavity is monitored in real time, through the corresponding relation between the water pump flow and the pressure, water pump descending can be found in time, necessary measures are taken, and the failure that due to cooling liquid flow descending, the engine is poor in cooling is avoided.
Description
technical field [0001] The invention relates to the technical field of engine cooling systems, in particular to an engine water pump. Background technique [0002] Typical belt-driven water pump configurations for existing engines, such as figure 1 As shown, the water pump pulley 11 is arranged coaxially with the water pump shaft 12 , and the water pump shaft 12 is installed in the water pump body 13 . Driven by the water pump pulley 11, the water pump shaft 12 rotates together, and the impeller 16 rotates, so that cooling water is sucked in from the water pump inlet 17, and produces high pressure in the water pump high-pressure chamber 14, and is finally discharged from the water pump outlet 15. [0003] Because engine water pump belt life is uncontrollable, damage is difficult to predict. Once the tension of the water pump belt drops or is damaged or broken, the force driving the water pump pulley 11 will drop, and the water pump pulley will drop (or be zero) when the wa...
