5) Good structural strength:
An anti wave mechanism is installed inside the tank to reduce the impact of clean water on the front and rear heads of the tank during vehicle operation, and to enhance the rigidity of the tank.
6) Safety design:
The bottom of the tank is equipped with an anti vortex device. When the vehicle is in operation, the water level inside the tank will continuously decrease, forming a deep vortex at the outlet. At this time, some air begins to be sucked into the water pump, causing unstable flow rate and poor operation effect. When the noise increases severely, cavitation may also occur, affecting the service life of the water pump. Adding this device can prevent vortex formation, improve the utilization rate of clean water, and extend the service life of the water pump.
