High water temperature is one of the most common faults of excavator operation in summer. There are various reasons for the faults, such as thermostat, blocked water tank, loose belt of fan blade, blocked water pump and waterway or poor water supply.
What I want to tell you today is the "engine cylinder gasket factor" because of the high water temperature of the excavator and the oil leakage of the excavator In the tens of thousands of excavator accessories, the gasket is almost one of the most inconspicuous parts. However, this cannot deny the important role of the gasket. The most basic is to prevent other parts from loosening. In addition, it also plays a role in preventing oil leakage, leakage and leakage Then the problem comes. There are many parts that can be used in daily life, and there are many kinds of gaskets, such as asbestos, rubber, insulation, spring, etc. How to choose the most suitable one? How to ensure that the service life of the replaced gasket is longer?
The cylinder gasket of the engine is generally made of iron at the time of delivery, but after working for a period of time, the cylinder gasket fails and needs to be repaired or replaced. Some engine owners will install non original or asbestos gaskets to replace it, which virtually reduces the compression ratio. Over time, the engine is likely to have trouble starting As we all know, the gaskets used in the fuel injector and the cylinder head are made of copper, which is to achieve the expected heat dissipation effect. If the engine owner purchases asbestos gaskets or iron gaskets during maintenance and installation, the heat dissipation effect will definitely not reach the expectation, and the fuel injector will be burnt in a short time
There are also gaskets between the oil transfer pump and the diesel pump. The gaskets here have strict requirements on the thickness. Therefore, when purchasing, the engine owner must strictly follow the size. Once the gasket is too thick, the oil transfer volume and pressure will be insufficient, resulting in power reduction For example, there are many kinds of gaskets in the repair kit. Some of the gaskets have holes but need to be opened by the machine owner during installation. Sometimes, due to carelessness, the machine owner forgets to open holes, which can easily lead to problems such as boiling of the water tank, clogging of the oil path and blocked water channel
In the process of maintenance, the installation gasket is not completely tight, that is, the joint surface is not in place, so there are problems such as looseness and oil leakage after a little time. When encountering a fault, all the owners are willing to scratch their heads, so they must be careful and meticulous in the initial installation
