派克電磁閥D1VW022CNJW換向閥方向閥現(xiàn)貨

D1VW 系列方向閥為NG06 規(guī)格的三油腔閥體方向控制閥，采
用濕式電磁鐵直動操控。能在極小、節(jié)能的壓降下，提供高達
80 l/min 的極限流量。
該系列方向閥具有十分多樣的閥芯型式選項，能滿足任何類型
的液壓回路設(shè)計。
D1VW 系列方向閥可有8W 電磁鐵、閥芯位置監(jiān)控、防爆、戶
外使用條件(表面防護) 及不同的電氣接口等多種類型供選擇，
以滿足不況要求，相關(guān)的資料將在后續(xù)的章節(jié)中提供。

基本公式
流量 (q)q =D x n /1000 x ηv[l/min]
扭矩 (M) M=D x Δp x ηhm/63[Nm]
功率 (P) P =q x Δp x ηt/600 [kW]
D – 排量 [cm3/rev]
n – 軸轉(zhuǎn)速 [rpm]
ηv – 容積效率
Δp – 進油口和出油口之間的壓差 [bar]
ηhm – 機械效率
ηt – 總效率(ηt = ηv x ηhm)
