The two anti-use oils do not change the viscosity of the road lubricants depending on the temperature, and the viscosity decreases when the temperature rises. Therefore, the engine oil of HC-11 diesel engine should be replaced in the summer. If the engine wear is large, the bearing gap is large, and the oil pressure is low, then use HC-14 diesel engine oil. In addition, try to use high-condensation grade diesel, so the low price can reduce costs.
The three anti-tire air pressure is high and high temperature season, and there is a large temperature difference between day and night. As the temperature rises, the volume of thermal expansion of the air increases, and the pressure of the tire increases. This can easily lead to tire blasting and cause unnecessary economic losses. Therefore, inflating the tires in summer should be 5%-7% lower than in winter. Never allow the pressure higher than the standard tire pressure.
Four anti-engine over-scale thick engine water jacket scale is too thick, will reduce the cooling efficiency by 30% -40%, easily lead to engine overheating, resulting in engine work deterioration, power reduction, stuck nozzle, leading to serious accidents. Therefore, it is necessary to regularly remove scale and maintain good cooling performance.
Five anti-friction tape tapes are tight and loose at high temperatures. The degree of tape tension decreases, causing tape slippage, large transmission loss, and easy tape damage. Therefore, in the summer, cold car adjustment engine belt tension is slightly higher than the standard value.
Oil barriers in six oil brakes Some transport tractors use hydraulic brakes. In high temperature summer, the oil brake brake pipeline is prone to air resistance, which seriously affects the braking effect. Therefore, in use, one must ensure that the brake oil is full, and secondly, prevent the pipeline from leaking. Thirdly, when air resistance occurs, it must be timely. Drain the air.
The higher the air resistance temperature of the seven anti-fuel systems, the faster the fuel (especially gasoline) will evaporate, and the easier it will be to create an air resistance in the oil circuit. Therefore, the fuel filter should be cleaned in time to make the oil circuit open. A wet cloth can be used to cover the fuel pump, and the water can be moistened regularly to reduce the generation of air resistance. Once the fuel has air resistance, it should immediately stop cooling, and pull the hand pump to discharge the air, so that the oil is full of fuel.
The eight oxidation prevention circuit malfunctions. Summer temperatures are high and humidity is high. The battery generates hydrogen gas, oxygen gas, and water vapor during operation. If the ventilation hole is blocked, the internal pressure of the battery will rise and cause burst. Therefore, it must be dredged regularly.
In air with high temperature and high humidity, the poles of the battery are easily oxidized, resulting in failure of the whole vehicle, such as no electricity, difficulty in starting, and failure of the electrical system. Need to remove the wiring from the pole pile, use the emery cloth or saw blade to polish the oxide layer, remove it and install it firmly. To prevent re-oxidation of the pole stakes, grease or Vaseline may be applied after installation to ensure air separation.
Nine defenses against the use of the battery in the absence of water in summer high temperatures, battery water evaporation in the electrolyte quickly, the liquid surface drops quickly, and even the plates exposed liquid surface, causing the battery to be damaged due to lack of water. Therefore, summer should always check the electrolyte surface above the plate height (usually 10-15 mm) and electrolyte density, if necessary, add distilled water to keep the battery in good working condition.
"Nine Defenses" Used in Summer Locomotives
The engine temperature is too high. Summer temperatures are high, affecting the engine's power. In case of using the engine to open the pot in use, most of the cases are lack of water in the tank, but at this time must not be added cooling water immediately, otherwise it will cause the cylinder head or cylinder burst. The right approach: stop running, run at low speed, wait until the water temperature drops to about 70°C, and then slowly add clean cooling water. Overload operation not only raises the water temperature quickly, but also easily damages the parts. Therefore, under normal circumstances the load should be controlled at about 90%, leaving 10% as a load reserve in order to cope with the short-term overload caused by uphill or arable land resistance changes.
