AI Technical Summary
Existing hydraulic oil ultrafiltration systems cannot simultaneously filter hydraulic oil when backflushing is required after the filter membrane has been filtered, resulting in reduced filtration efficiency.
The hydraulic oil ultrafiltration system, controlled by a servo motor, achieves online backwashing cleaning of the filter membrane by switching between the main liquid pipe and the auxiliary liquid pipe. The rotation of the valve core is controlled by synchronous pulleys and synchronous belts, enabling the filtration and backwashing of hydraulic oil to be carried out in parallel.
It improves the overall cleaning efficiency of the hydraulic oil filtration system, avoids interruption of filtration during filter membrane backflushing, and enhances filtration efficiency.
