No matter in winter or summer, careful excavator masters can often find a strange phenomenon in the excavator, that is, the engine water tank is often short of water! The water added the day before started to run out again the next day! The cycle goes back and forth but I can’t figure out what the problem is. Many people do not take the phenomenon of water leakage or water shortage from the water tank seriously and think that as long as it does not hinder the normal construction of the excavator, they can be ignored and not dealt with. I would like to tell everyone responsibly that this idea must be abandoned!
We all know that as the main component of the engine cooling system, the water tank’s function is to dissipate heat and achieve the ability to reduce the engine temperature. Specifically, when the engine water temperature is too high, the thermostat opens, and the water pump circulates water repeatedly to reduce the engine temperature. (The water tank is made of hollow copper tubes. High-temperature water enters The water tank is air-cooled and circulated into the engine water channel) to protect the engine. If the water temperature is too low in winter and the thermostat does not open, the water circulation will be stopped at this time to prevent the engine temperature from being too low.
Simply speaking, the function of the auxiliary water tank is that when the engine water temperature is high, the water in the water tank will flow to the auxiliary water tank due to thermal expansion and contraction. When the temperature drops, it will flow back to the water tank. There will be no waste of coolant in the whole process. , which is what the saying goes: lack of water.
It can be seen that when water leakage or water shortage occurs in the water tank, the ability to cool the engine is greatly reduced, and the ultimate purpose of protecting the engine cannot be achieved. When this fault occurs, the first thing to check is whether the auxiliary water tank is damaged or leaked. Leaky point. The role of the auxiliary water tank is very important, and the auxiliary water tank ages very frequently due to reasons such as material and frequency of use, so the owner needs to check regularly for damage.
If your excavator water tank is also short of water, you must pay attention to it as soon as possible after reading this article.
