The following aspects should be noted when using bimetallic cylinder liners.
Firstly, its operating temperature should be strictly controlled. The working temperature of bimetallic cylinder liners, whether too high or too low, can exacerbate wear and affect their service life and work efficiency. Generally speaking, the normal operating temperature of the engine should be maintained at 80-90 ℃. If the temperature is too low, the lubrication effect of the cylinder wall will decrease, wear will increase, and water vapor inside the cylinder may condense into water droplets, which combine with acidic gases in the exhaust gas to form acidic substances and corrode the cylinder wall. If the temperature is too high, it may lead to a decrease in cylinder strength, exacerbate wear, and even cause“ Expansion cylinder; accident.
Secondly, when operating the bimetallic cylinder liner, attention should be paid to the correct starting and start-up procedures. When starting a cold car, due to the high viscosity and poor fluidity of the engine oil, the cylinder wall may not receive good lubrication. Therefore, the engine should be idling a few times before starting, and the friction surface should be lubricated before starting. After starting, the engine should run at idle speed to increase the temperature. It is strictly forbidden to press the accelerator pedal forcefully. Wait until the oil temperature reaches 40 ℃ before starting.
In addition, safe operation is also an important aspect that cannot be ignored when using bimetallic cylinder liners. Non technical personnel should avoid operating bimetallic cylinder liners, especially in environments where toxic and harmful gases may be encountered during drilling operations. Operators must wear anti-virus equipment. During installation, operation, disassembly, and maintenance, safety habits should be followed to ensure that operations are carried out under appropriate lighting and to avoid operating equipment when visibility is low.
Overall, in order to ensure the normal operation of bimetallic cylinder liners and extend their service life, it is necessary to strictly control their operating temperature, follow the correct operating procedures, and always prioritize safety.
