Precautions for the operation of internal combustion forklift engines

The engine as the heart of internal combustion lithium pallet truck trucks is an important hub that cannot be ignored. The various components of internal combustion forklift trucks and the engine are inseparable. How to protect the engine for long-term useful employment has become the primary indicator to weigh the advantages and disadvantages of an internal combustion forklift truck. However, what must not be included is that the poor control of behavior is also a major part of the cause of this. Today, Xiao Yang of Linggong will send you an understanding of the precautions for diesel engines.

First: The engine cannot stop immediately after running at high speed for a long time.

The reason is that when the engine is in employment, a part of the engine oil is supplied to the smooth rotor bearing and used to cool the engine. After a sudden shutdown, the oil pressure quickly drops to zero, and the oil is smooth and intermittently. The heat in the turbocharger can not be taken away by the oil. At this time, the heat of the turbocharger will be transferred to the period, and the bearing will support the shell. The heat cannot be taken away quickly, and at the same time the supercharger rotor is still spinning at high speed under inertia. This becomes a bite between the supercharger and the shaft sleeve and damages the bearing and shaft. In addition, after the engine is suddenly turned off, the temperature of the exhaust pipe is very high at this time, and its heat will be absorbed into the shell of the supercharger, and the oil staying in the supercharger will become carbon deposits. The more time it takes, the oil inlet will be blocked, causing lack of oil in the bearing, and accelerating the wear between the shaft and sleeve. Therefore, it is recommended that the engine should be idle for three minutes before the engine is turned off to reduce the speed of the turbocharger rotor. It is just like a supercharger engine that is not suitable for long-term idling, usually within 10 minutes.

Second: Pay attention to the use of oil

In view of the usefulness of the supercharger, the air quality and volume of the combustion chamber are greatly improved, and the engine structure is more compact and more suitable , The higher shrinkage ratio makes the employment intensity of the engine higher, the machining accuracy is also improved, and the installation skills are relatively stricter. All of these are considered to be the tropical, high-speed, high-power, high-torque, and high-torque characteristics of supercharged engines. Low-emission employment characteristics. At the same time, it is determined that the internal parts of the engine must withstand higher temperatures and greater impact, extrusion and shear forces. Therefore, when using car oil, it is necessary to consider its particularity. The oil used must have good abrasion resistance, heat-resistant belt, set up a smooth oil module, high oil film and good stability, combined oil or semi-combined oil Engine oil happens to meet this condition, so in addition to engine oil, it is best to use the original factory-designated engine oil, but also may choose to use high-quality smooth oil such as combined oil and semi-combined oil.

Third, the engine oil and filter must be kept clean

In order to prevent the magazine from coming in, the clearance between the shaft and sleeve of the turbocharger is too small, if the oil is smooth When talents fall, it will become premature supercharger scrapping.

Pay attention to the above points, which will extend the life of diesel forklifts. For this good deputy, it is also an extension of life and creates more benefit.
