AI Technical Summary
Traditional hydraulic pump inlet filters require manual cleaning, which is cumbersome and affects system efficiency. Existing filters with automatic cleaning functions have complex structures and unsatisfactory cleaning effects.
A self-cleaning hydraulic pump inlet filter was designed. A pressure sensor detects blockages, and a motor drives a scraper and a tilting plate to automatically clean impurities. Combined with an impurity collection structure and a slag discharge channel, automated impurity removal is achieved.
It achieves automated impurity removal, prevents clogging, improves fluid flow, enhances filtration efficiency and convenience, and reduces impurity residue.
