[China Agricultural Machinery Industry News] Three summers are coming, and all parts of the country are actively preparing for the "three summers." Three summers are not only the harvest season, but also the frequent occurrence of agricultural accidents. Therefore, in order to reduce the accident rate and ensure normal operation and driving safety, care should be taken.
In the summer, the use of agricultural machinery should pay attention to this "eight items"
Three summers are coming, all kinds of agricultural machinery must go to their jobs, in order to ensure their correct driving and safe operation, minimize the occurrence of various types of agricultural machinery accidents, extend the service life of the equipment, and pay attention to the following matters when using agricultural machinery in summer:
Take care to prevent the engine from overheating. In most cases, the water tank is short of water. At this time, the cooling water cannot be added immediately, which may cause the cylinder head or cylinder to burst and burn people. The correct way is to stop running, run at low speed, wait until the water temperature drops to about 70 °C, then slowly add clean cooling water.
Take care to prevent the engine tank from being too thick. If the scale of the engine water jacket is too thick, the heat dissipation efficiency will be reduced by 30% to 40%, which may cause the engine to overheat and reduce the power. Therefore, the scale should be cleaned regularly to maintain good cooling performance.
Take care to prevent air blockage in the fuel system. Once the fuel has a gas resistance, stop it immediately and cool down, and pull the hand pump to remove the air, so that the oil circuit is full of fuel.
Take care to prevent the use of oil. The viscosity of the lubricating oil changes with the temperature, and the viscosity decreases when the temperature rises. ECA-30 or ECA-40 diesel engine oil should be used in summer.
Take care to prevent the fan tape from being loose. When working at high temperatures, the tape tension is reduced, causing the tape to slip, the transmission efficiency is lowered, and the tape is easily damaged. Therefore, the summer cold car adjustment engine tape tension is slightly higher than the standard value.
Take care to prevent fire. Always check the tightness of each wire and fuel pipe joint to prevent sparks caused by poor contact or fuel pipe leakage.
Take care to prevent the tire pressure from being high. When the temperature rises, the air heat rises and the volume increases, which easily causes the tire to burst. Inflating the tires in summer should be 5% to 7% lower than in winter, and never exceed the standard pressure of the tires.
Take care to prevent air blockage in the oil brake line. In the high temperature summer, the brake circuit of the oil brake is prone to air resistance, which seriously affects the braking effect. Therefore, in use, one must ensure sufficient amount of brake oil, and secondly, prevent leakage of the pipeline. Third, timely occurrence of air resistance Drain the air.
