升降貨梯上升速度有哪些規(guī)定？

升降貨梯http://www.jntr168.com/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(jì)不合理造成，那么對(duì)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(shí)，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(shí)，低速下的速度剛度好，當(dāng)負(fù)載變化時(shí)，負(fù)載小時(shí)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.jntr168.com/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.
