Forklift fittings and fittings are characterized by a decrease in speed, inability to operate, a tumultuous sound, and an extremely high water temperature, with an indication of a water temperature gauge spanning 100 °C. At this point, sprinkle some water on the parts and it will evaporate quickly. The main cause is severe water shortage and the water cooling system fails. If the flame is stopped immediately, the sticking cylinder may occur. Forklift fittings and fittings, idle speed for a period of time or flame-extinguised crankshaft auxiliary cooling, so that the water temperature is reduced to about 40 °C, and then slowly add cooling water. Be careful not to add cooling water immediately, as this will cause the parts to deform or crack due to a sudden drop in local temperature.
Cylinder failure
Forklift fittings and fittings: The crankcase has a "click" sound, like a small hammer tapping the sound of a hard floor, commonly known as "knocking sound", the oil pressure drops, and the acceleration is more obvious. The cylinder is a destructive mechanical failure, mainly due to the loosening of the connecting rod bolt or the bolt pulling the telescopic neck. The connecting rod shaft has a large clearance, which causes the bolt to loosen or break. If there is a knocking sound, but the oil pressure is normal, it is not a sign of the cylinder, and should be considered from adjusting the fuel supply advance angle. Forklift fittings and fittings, immediately shut down for repairs and replacement of new parts.
Burning tile failure
Forklift fittings and fittings: The sound is boring, as if the load suddenly increases the speed, the oil pressure drops, and the exhaust smokes black smoke. Burning the tile will cause the bearing bush and the journal to lock and extinguish. The main reason is that the lubricating oil film on the surface of the bearing bush is broken, the bearing bush is in direct contact with the metal on the surface of the journal, and the friction temperature rises rapidly, resulting in gluing. Forklift fittings and fittings, immediately stop the machine, check the connecting rods, bearing bushes, find out the reasons, repair and replace.
