Regular maintenance of the precision oil filtration unit is essential; it not only extends the equipment's service life and improves operational efficiency but also allows for the timely detection of wear and tear.
Specific maintenance procedures are as follows: When shutting down the unit after operation, first turn off the heater, then stop the oil inlet pump, followed by the oil discharge pump. Close the inlet and outlet valves; once the pressure/vacuum gauge reading indicates the required operating vacuum level, close the vacuum valve and stop the vacuum pump. Operate the cooling pump to drain oil from the condenser, then close the remaining valves and disconnect the main power supply. If the ambient temperature drops below 0°C or the unit remains idle for more than a month, drain all water from the water tank. When operating in environments with temperatures below 15°C, the vacuum pump oil must be heated to approximately 15°C before starting the unit. If the oil to be purified is excessively dirty, appropriate pre-treatment measures should be taken to avoid compromising the unit's service life. If internal cleaning is required due to heavy contamination or prolonged use, close the outlet valve, open the bypass valve, and perform an internal circulation wash following the standard startup procedure; after discharging the cleaning oil, replace the inlet and outlet filter papers and clean the metal mesh of the primary filter.
