maintenanceHydraulic oil coolerThe key measures to ensure its continuous and stable operation and extend its service life are as follows:
Regular inspection and cleaning:
Regularly inspect the appearance of the hydraulic oil cooler, including the radiator, fan, fins, housing, and other parts, to ensure that the equipment is not damaged or in any abnormal condition.
Regularly clean the radiator, fins, and casing of the hydraulic oil cooler to remove dust, oil stains, and debris, and maintain the cleanliness and heat dissipation of the equipment.
Clean the air filter every two weeks (at least once a week in harsh environments). When cleaning, first remove the filter and use a vacuum cleaner or air gun to remove dust. When the dirt is severe, the air filter should be cleaned with warm water and neutral detergent at a temperature not exceeding 40 ℃.
Regularly check the oil level in the fuel tank to ensure that the oil cooler does not operate without or with low oil. According to the oil quality, conduct a comprehensive inspection and cleaning of the oil system every 3 to 6 months.
After long-term storage and reuse or prolonged use, the oil cooler heat exchanger should be checked for blockage by dust and dirt. If necessary, dry compressed air, vacuum cleaner or soft bristled brush should be used to clean its surface once.
Regularly replace components:
Regularly replace the filter element in the hydraulic oil cooler to maintain the cleanliness and filtering effect of the hydraulic oil.
Regularly replace hydraulic oil to remove impurities and pollutants from the oil, ensuring the normal operation of the hydraulic system. According to the actual situation, the replacement cycle of hydraulic oil is generally 6 to 12 months.
Regularly discharge the condensed water in the hydraulic oil cooler to avoid water accumulation inside the equipment, which may affect the heat dissipation effect and service life.
Regularly lubricate the fan bearings to extend the service life of the fan and ensure the normal operation of the equipment.
Monitoring of operational status:
Monitor the operation status of hydraulic oil cooler, including cooling effect, noise, vibration, etc.
Pay attention to the changes in oil temperature and ensure that the oil temperature fluctuates within the set range. If abnormal conditions such as abnormal oil temperature rise or alarm indicator light are found, the machine should be stopped immediately for inspection and troubleshooting.
Operating standards:
The hydraulic oil cooler should be installed in a well ventilated and dry environment, and ensure that the equipment is kept at a certain distance from surrounding objects to ensure air circulation and heat dissipation.
Select hydraulic oil that meets the equipment requirements and ensure that the quality and cleanliness of the oil meet the requirements. At the same time, it is prohibited to mix different grades of hydraulic oil to avoid chemical reactions that may affect equipment performance and service life.
The chilled water pump cannot operate without water in the water tank; The operation switch should avoid continuous switching as much as possible; The temperature switch should be avoided from being set below 5 ℃ (except for low-temperature freezers) to prevent the evaporator from freezing.
