升降貨梯http://www.jxpj.com.cn/速度不穩(wěn)定主要是由液壓系統(tǒng)提升調(diào)速回路設(shè)計不合理造成,那么對于升降貨梯上升速度有哪些規(guī)定呢?
1、當(dāng)升降貨梯負(fù)載不變時,節(jié)流閥口進(jìn)越小,則系統(tǒng)速度剛度進(jìn)越高;反之,若節(jié)流閥開口面積越大,則進(jìn)越低。
When cargo lifter constant load, throttle opening into the smaller, the system speed into higher stiffness; on the contrary, if the larger throttle opening area, then into the lower.
2、當(dāng)升降貨梯負(fù)載不變時,低速下的速度剛度好,當(dāng)負(fù)載變化時,負(fù)載小時的速度剛度好。
When constant load cargo lifter, low speed speed stiffness, when the load changes, load hour speed stiffness.
3、提高升降貨梯http://www.jxpj.com.cn/供油壓力加大液壓缸有效作用面積,可提高速度剛度。
Increasing pressure to improve cargo lifter oil hydraulic cylinder effective action area, the speed can be increased stiffness.
