The summer heat not only tests our bodies, but also makes excavators and other heavy equipment face serious challenges. Want to equipment in the summer heat stable operation, reduce failure, these summer maintenance tips can be remembered!
First, water temperature monitoring, lack of water is not a rush to make up for
High-temperature operation, the cooling system is the excavator's “cooling magic weapon”. Be sure to keep a close eye on the water temperature meter, once the secondary water tank water is found to be insufficient, do not rush to make up water. You should first let the excavator idle to cool down, and then slowly add water, and add water, remember to stay away from the radiator cap, to avoid high-temperature steam burns.
Second, the oil new, more durable heat resistance
Lubricating oil is easy to dilute at high temperature, affecting the lubrication effect and accelerating oxidation. In summer, you should use special lubricant, regularly check the oil level and oil quality, and replace it in time to ensure that the engine, the heart of the excavator, is always protected by the best lubrication.
Third, oil cleaning, more efficient heat dissipation
Engine external oil pollution is too thick, will hinder heat dissipation, increase the risk of failure. Use professional cleaning agent high-pressure flushing, but pay attention to avoid the electrical wiring harness, in order to prevent short circuit. Regular cleaning, so that the excavator “breathing” more smoothly.
Fourth, the water tank cooling, multi-pronged approach
Water tank high temperature is a common problem in summer, need to start from various aspects:
Regularly change antifreeze: choose Sany pure antifreeze and replace it according to the maintenance cycle to ensure the cooling effect.
Water tank inside and outside the clean: regularly clean up the water tank inside and outside, keep unobstructed.
Heat-insulating cotton installation: add heat-insulating cotton around the water tank to reduce hot air reflux.
Fan belt tightening: adjust the fan belt tightness, ensure the fan speed, enhance the cooling efficiency.
Fifth, oil supply time, precise adjustment
The oil supply time is crucial to the performance of the excavator. If the oil supply is too early, the engine will rattle; if the oil supply is too late, the power will be insufficient. Non-professionals should not make adjustments on their own, and must contact Sany's professional engineers for debugging to ensure accurate oil supply.
Sixth, viscosity upgrade, lubrication more in place
Use high viscosity lubricant in summer to improve lubrication performance and sealing. When replacing, don't forget to thoroughly clean the oil filter, filter collector and oil sump to make the lubrication system look new.
Seven, battery care, power often enough!
Battery is the excavator's “power heart”. When not in use for a long time, it should be removed and stored in a ventilated dry place, and charged every 15-20 days to maintain sufficient power. At the same time, keep the battery external clean, prolong the service life.
High-temperature operation is not only a test of machinery, but also a 'common battle moment' between people and equipment. When you take good care of the equipment, don't forget to give yourself a cup of herbal tea, rest in the shade for five minutes - your safety and health is the foundation of the efficient operation of the equipment.
