(2) Coarse Filter – 100 μm.
(3) First-Stage Precision Filter – 25 μm / 40 μm.
(4) Second-Stage Precision Filter – 3 μm / 5 μm / 10 μm.
(5) Motor – Dual-motor drive.
(6) Pressure Gauge – System pressure monitoring.
(7) Overflow Valve – Overpressure protection.
(8) Heating System – Independent heating module for low-temperature operation.
(9) Consumable Filter Elements – Replaceable as needed.
Test Procedures
Ensure oil hoses are connected correctly and inlet/outlet valves are open.
Check power supply, motor status, and protection devices.
In low-temperature environments, start the heating system to bring oil to the required viscosity before operation.
Monitor pressure gauges during operation to avoid overpressure.
Replace filter elements promptly if the differential pressure rises significantly.
Before shutdown, close the inlet valve, depressurize the system, and then cut off the power.
Maintenance Information
Regularly inspect hoses, filter elements, and protection devices for wear or damage.
Replace filter elements according to operating hours or differential pressure readings.
Clean the system periodically to prevent sediment buildup.
Verify operation of the heating system and overflow protection before each use.
Record operation data to monitor system performance over time.
