一、水箱散热管堵塞引起水温过高当水箱散热管被水垢及污物堵塞后,冷却水通过时阻力增大,使循环水量减少影响散热效果,造成水温过高以至“开锅”。散热管堵塞可由下述现象判断:当油门加大时,由于水泵转速增高,抽水能力强,将水箱上室的水强制吸到下室然后进入水泵,从而水箱水位降低;当油门减小时,已循环到水箱上室的水,不能畅通流入下室而使水位增高,并从水箱口溢出;另外,当发动机熄火后,水箱里有“咕噜—咕噜”的响声。此时应拆下水箱芯,彻底清除散热管中的水垢和污物。为了防止散热管堵塞,可将散热扁管的上端开口处用手钳稍微夹扁一些(缩小约三分之一),这样能进入散热管里的水垢将不易卡在管内,避免堵塞。时 First, the water tank heat pipe blockage caused by water temperature is too high When the water tank heat pipe is scale and dirt clogging, the cooling water through the resistance increases, so that the impact of reduced circulating water cooling effect, causing the water temperature is too high and even “boil”. Blockage of the heat pipe can be judged by the following phenomena: when the throttle is increased, the water level in the upper chamber of the water tank is forced to be sucked into the lower chamber due to the increase of the rotational speed of the water pump, and then the water pump is lowered, so as the water level of the water tank is reduced; The water circulated to the upper chamber of the water tank can not flow smoothly into the lower chamber to increase the water level and overflow from the tank mouth. In addition, when the engine is off, there is a sound of “grunt-grunt” in the water tank. At this point should remove the tank core, completely remove the heat pipe scale and dirt. In order to prevent blockage of the heat pipe, the upper end of the heat-radiating flat pipe can be slightly clamped with hand pliers (about a third of the diameter) so that the scale entering the heat pipe will not be stuck in the pipe and the blockage will be avoided.
