ATOS阿托斯比例溢流閥調(diào)試經(jīng)驗

 

 

經(jīng)驗交流

 

ATOS阿托斯比例溢流閥首先由電氣技術(shù)員在壓機調(diào)整狀態(tài)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4,56…….25MPa的信號,使壓機強行由比例溢流閥溢流;每個壓力反復(fù)測試5次,反復(fù)觀察,看每次溢流是否穩(wěn)定。

 

一、如果波動穩(wěn)定由電氣技術(shù)員按下行方式編程完成調(diào)試。

1、力士樂比例溢流閥按以下曲線和函數(shù)進行調(diào)試

注:電壓、電流型的曲線P、IV均為百分比單位,需要換算成整數(shù)。

2、atos阿托斯比例溢流閥   由于是數(shù)字放大板對的控制閥,用Atos數(shù)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(huán)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(shù)。

 

但低壓時存在超調(diào)現(xiàn)象,通過PID調(diào)整解決

由電氣技術(shù)員按上述方式編程完成調(diào)試。

二、如果通過以上打點反復(fù)測試,從45,,6…….25MPa的信號,壓力波動無規(guī)律,則由液壓技術(shù)員和鉗工調(diào)整阻力螺釘,達(dá)到無波動后在編程。

阻力螺釘調(diào)整規(guī)則如下:

2、阿托斯作先導(dǎo)閥與泰豐插件的匹配原則

主缸更換阻尼配置

X——φ1.2短孔

 F——φ 0.8 長孔

P——φ 1.5短孔

頂缸更換阻尼配置

X——φ1.0短孔

F——φ0.8長孔

P——φ1.2短孔

 

 

注:阻力孔更換原則僅供參考,視具體情況而定

  1. 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(yán)重,就會造成壓力控制精度不穩(wěn)定。
  2. 清潔度和油溫很重要,特別是油溫應(yīng)在40±5度的情況下,能使比例閥有一個很好的使用環(huán)境和穩(wěn)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(dǎo)油的流量,因為當(dāng)先導(dǎo)油路有油液流動時,我們可以認(rèn)為X口兩端的壓差等于插件復(fù)位彈簧力,所以X口阻尼大小可以結(jié)合插件復(fù)位彈簧力以及我們所選的先導(dǎo)流量來確定(一般我們?nèi)∠葘?dǎo)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(dāng)先導(dǎo)流量相對穩(wěn)定時,先導(dǎo)比例閥控制的壓力也相對穩(wěn)定,便于控制。

           F口阻尼的作用是對插件的開啟和關(guān)閉起一定的阻尼作用,可以消除超調(diào)或者震蕩現(xiàn)象F口阻尼的大小需要結(jié)合插件彈簧腔的大小來選取,目前我公司選用的NG25NG32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(dǎo)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。
