According to the current development trend of engineering construction, many businesses purchase a certain amount of second-hand excavators every year, and these purchased excavator equipment will be put into local engineering or construction needs. But among these buyers who purchase and use second-hand excavators, there are many beginners. They have very little knowledge about this type of large machine. For example, a purchased oneSecond hand Hitachi excavatorDuring use, the engine experienced a problem of water ingress, and many people were unsure of what to do. So below, the editor will explain the relevant solutions to this problem.
Firstly, what we need to do is to carry out an emergency response. In general, it is common for the engine of a second-hand Hitachi excavator to experience water ingress during operation. So as long as we master the relevant handling methods, we can effectively solve the problem ourselves without having to spend unnecessary time and money hiring relevant maintenance personnel. If the engine is not damaged or deformed by water ingress, we can choose to lay a piece of sandpaper on the ground, remove the engine's water ring, and then grind it on top of the sandpaper. Once it is leveled, it can be put back into use again.

So we need to directly carry out relevant repairs on the excavator's engine. Considering the unique working environment of excavators, people generally lack the necessary repair conditions. At this point, we use changes in water temperature to regulate the temperature inside the engine. Firstly, connect the inlet and outlet ports of the engine's water pump separately. At this point, the circulation system of cold and hot water will be connected. So we can make full use of two different water temperature systems to adjust the temperature of the engine water pump on our own.
In addition, there is a relatively simple method of handling it. That's using a container, which can beSecond hand Hitachi excavatorA tire inside, or an oil drum on the construction site, etc. are all acceptable. Then fix it and take two pipes as a medium to connect the container and the engine water pump. It is worth noting that the water pump connected here should be located at the outlet, not the inlet. At this point, we will firmly tie both pipes separately. Ensure stable delivery of water flow.
Thirdly, if the engine of a second-hand Hitachi excavator is experiencing water ingress while the machine is in operation. At this point, we should adopt a different approach. Firstly, stop the machine from working in a timely manner, and then quickly adjust the stable speed of the excavator to the lowest. To achieve this effect faster, operators can also add a certain amount of cold water to the water pump to quickly cool down the engine. If the water pump ruptures due to not being able to detect the problem in time, then we should replace it with a new water pump component. Only in this way can second-hand excavator equipment truly eliminate the potential hazards caused by this problem and malfunction.
