ATOS阿托斯比例溢流閥調試經驗
經驗交流
ATOS阿托斯比例溢流閥首先由電氣技術員在壓機調整狀態下,按“滑塊下行"按鈕,泵和閥不斷電的情況下,給比例溢流閥壓力從4,5,6…….25MPa的信號,使壓機強行由比例溢流閥溢流;每個壓力反復測試5次,反復觀察,看每次溢流是否穩定。
一、如果波動穩定由電氣技術員按下行方式編程完成調試。
1、力士樂比例溢流閥按以下曲線和函數進行調試
- atos阿托斯比例閥電流型(4-20毫安輸入)

注:電壓、電流型的曲線P、I、V均為百分比單位,需要換算成整數。
2、atos阿托斯比例溢流閥 由于是數字放大板對的控制閥,用Atos數字軟件,給比例溢流閥壓力從4,5,6…….25MPa的信號,將比例閥切換至開環模式,觀察壓力有無震蕩。
如無震蕩,就按下一曲線編程,即為一次正比例函數。
但低壓時存在超調現象,通過PID調整解決
由電氣技術員按上述方式編程完成調試。
二、如果通過以上打點反復測試,從4,5,,6…….25MPa的信號,壓力波動無規律,則由液壓技術員和鉗工調整阻力螺釘,達到無波動后在編程。
阻力螺釘調整規則如下:
2、阿托斯作先導閥與泰豐插件的匹配原則
主缸更換阻尼配置
X口——φ1.2短孔
F口——φ 0.8 長孔
P口——φ 1.5短孔
頂缸更換阻尼配置
X口——φ1.0短孔
F口——φ0.8長孔
P口——φ1.2短孔
注:阻力孔更換原則僅供參考,視具體情況而定
- 注意溫度的變化對壓力精度控制的影響,溫度越高油的濃度越稀,泄漏越嚴重,就會造成壓力控制精度不穩定。
- 清潔度和油溫很重要,特別是油溫應在40±5度的情況下,能使比例閥有一個很好的使用環境和穩定性。
三個位置的阻尼孔的作用分別如下:
X口阻尼的作用是限制先導油的流量,因為當先導油路有油液流動時,我們可以認為X口兩端的壓差等于插件復位彈簧力,所以X口阻尼大小可以結合插件復位彈簧力以及我們所選的先導流量來確定(一般我們取先導流量在1L/min左右)。X口選擇短孔形式是因為短孔通過流量受油溫影響較小,當先導流量相對穩定時,先導比例閥控制的壓力也相對穩定,便于控制。
F口阻尼的作用是對插件的開啟和關閉起一定的阻尼作用,可以消除超調或者震蕩現象,F口阻尼的大小需要結合插件彈簧腔的大小來選取,目前我公司選用的NG25和NG32的插件,F口阻尼都可以選用0.8(阿托斯)、1.0(力士樂)左右。F口阻尼一定要選用長孔形式,因為長孔的阻尼效果明顯好于短孔。
P口阻尼的作用是對整個先導油路的流動起一定阻尼作用(包括X口和F口的流量),P口阻尼的大小可以略大于P口,選用短孔形式。
