The shell produces a downward thrust

The water pump housing of the riding motorcycle is installed in the front of the left axle box cover, while the water pump housing of the sitting motorcycle is actually installed in the front of the right axle box cover. When the impeller on the water pump shaft rotates, a vacuum is formed at the center of the impeller. The coolant from the hose under the radiator just leads to the center of the impeller and enters the pump. The impeller rotates with the coolant, and the coolant is thrown away due to the centrifugal effect of rotation. It is thrown to the outer edge of the impeller and has a certain pressure, and is transported to the water jacket of the cylinder under the guidance of the centrifugal guide groove at the outer edge of the impeller of the casing. When the temperature of the coolant is higher than the temperature of the coolant, the yellow wax in the inner cavity of the thermostat is heated to melt and become liquid, the yellow wax expands in volume, and the extruded rubber sleeve shrinks toward the center, thereby generating a pushing force on the lower end cone of the reverse push rod. The upper end is fixed, so the lower end cone of the reverse thrust rod produces a downward reverse thrust on the rubber sleeve and the shell, thereby compressing the spring to open the valve. At this time, the high temperature and cold cycle valve in the engine closes the large cycle valve and opens the shell. The rubber sleeve is yellow wax. . Thermostat The thermostat housing is generally installed at the outlet of the upper water jacket of the cylinder head, and the top leads to the right side of the radiator or the upper water tank. It is a switch or valve for the circulation route of the coolant in the cooling system. The upper bracket valve seat and the lower bracket are riveted into a whole. The cooling liquid of the radiator cover passes through the fully opened thermostat valve, flows from the top of the shell through the hose on the radiator to the radiator for cooling, and all the cooling liquid circulates between the radiator and the engine water jacket. When the temperature of the coolant is lower than that, the yellow wax in the thermostat gradually becomes solid, the volume is reduced, and the valve is seated and closed again under the action of the spring force. The radiator is composed of left and right (or upper and lower) water tanks and the radiator core. The radiator coolant flows from the right water tank through the radiator core, and then flows to the left pressure valve to open the water tank, which is called a cross-flow radiator. This kind of radiator is widely used in modern motorcycles, especially multi-cylinder engines.
