1. Open the oil cooler. From March to November every year, the operator is required to open the oil cooler in time to ensure the normal operation of the equipment, and the oil cooler is opened when the equipment is started for each shift.
2. Observation of oil cooler. The oil cooler is set with a certain cooling temperature value. When the operator usually operates the equipment, it is necessary to observe the display value of the oil temperature. When the oil temperature is higher than the set value for a long time, it is necessary to reflect the situation to the maintenance in time.
3. Clean the tank. When the oil cooler runs for about 2 weeks, the oil tank drain port should be opened to drain the oil to remove the water entering the bottom of the tank sink. The cooling coils of the LO-C unit should be cleaned regularly to prevent a reduction in cooling capacity. The cooling coil should be avoided when cleaning, and the bottom of the tank should be completely cleaned.
4, clean the air filter. Clean the air filter every two weeks (at least once a week when the environment is bad). When cleaning, remove the filter and remove the dust with a vacuum cleaner or air spray gun. When the dirt is serious, the air filter should be cleaned with warm water and neutral detergent at a temperature of not more than 40 ° C. After cleaning, dry the water and then put it back in place.
5. Check regularly. According to the cleanliness of the oil, regularly check and clean the oil filter to prevent dirt blockage.
6, clean the surface of the unit. When the surface of the unit is dirty, it should be scrubbed with a soft cloth with neutral detergent or high quality soapy water. Do not use petroleum, acid solvents, grinding powder, steel brush and sandpaper to prevent damage to the spray surface.
7. Check before re-use. After long-term placement and re-use or use for a long period of time, check whether the heat exchanger of the oil cooler is blocked by dust and dirt. If necessary, the surface should be cleaned with dry compressed air, a vacuum cleaner or a soft brush. Be careful not to damage the fins of the heat exchanger when doing this.
