節(jié)流口堵塞原因:
1、油液中的機(jī)械雜質(zhì)或因氧化析出的膠質(zhì)、瀝青、碳渣等污物堆積在節(jié)流縫隙處。
2、由于油液老化或受到擠壓后產(chǎn)生帶電的極化分子,而節(jié)流縫隙的金屬表面上存在電位差,故極化分子被吸附到縫隙表面,形成牢固的邊界吸附層,吸附層厚度一般為5~8微米,因而影響了節(jié)流縫隙的大小。以上堆積、吸附物增長到一定厚度時,會被液流沖刷掉,隨后又重新附在閥口上。這樣周而復(fù)始,就形成了流量的脈動。
3、閥口壓差較大時,因閥口溫度高,液體受擠壓的程度增強(qiáng),金屬表面也更易受摩擦作用而形成電位差,因此壓差大時容易產(chǎn)生堵塞現(xiàn)象。
減輕節(jié)流口堵塞的措施:
1、選擇水力半徑大的薄刃節(jié)流口。
2、精密過濾并定期更換油液。
3、適當(dāng)減小節(jié)流口前后的壓差。
4、采用電位差較小的金屬材料、選用抗氧化穩(wěn)定性好的油液、減小節(jié)流口表面粗糙度。
