PROSOFT 5204-DFNT-PDPMV1 可編程控制器
許多汽車和燃氣發(fā)動機油、工業(yè)潤滑油以及礦物或合成來源的其他油都滿足這些要求。5204-DFNT-PDPMV1調(diào)速器設計用于在粘度在50至3000 SUS（賽博爾特通用秒）之間的大多數(shù)油的工作溫度下提供穩(wěn)定的工作。在正常工作溫度下，粘度應在100至300 SUS之間。致動器響應差或不穩(wěn)定可能表明機油粘度在該范圍之外。調(diào)速器中的部件過度磨損或卡住表明可能存在以下情況：1。潤滑不足的原因是：?機油在低溫時流動緩慢，尤其是在啟動期間?調(diào)速器2中沒有機油。受污染的油是由以下原因引起的：?油箱臟?調(diào)速器暴露在加熱和冷卻循環(huán)中，導致油中的水凝結(jié)3。機油不適合工作條件是由以下原因引起的：?環(huán)境溫度變化?油位不合適，會產(chǎn)生泡沫、充氣機油。連續(xù)操作調(diào)速器超過機油的上限溫度將導致機油氧化。這可以通過調(diào)速器零件上的清漆或污泥沉積物來識別。為了減少油的氧化，用熱交換器或其他方式降低執(zhí)行機構(gòu)的工作溫度，或換成在工作溫度下更耐氧5204-DFNT-PDPMV1 化的油。如果粘度超過50至3000 SUS范圍，則可能導致失去穩(wěn)定的調(diào)速器控制和原動機超速。原動機超速和/或失控可能導致設備大面積損壞、人身傷害和/或生命損失。
通過一個小面板孔可以看到內(nèi)部止動桿上的中心沖壓標記，該標記指示調(diào)速軸的最小速度位置。最小和最大止動位置是帶防松螺母的可調(diào)節(jié)止動螺釘。該連桿不得有束縛或空轉(zhuǎn)。連桿連接必須采用適當?shù)逆i定方法。供油根據(jù)調(diào)速器的工作溫度使用機油（見表2-1）。5204-DFNT-PDPMV1主要關(guān)注調(diào)速器中的機油特性。向調(diào)速器加注約1.5 US qt（1.4 L）的機油，直至油位觀察鏡上的標記。發(fā)動機起動且調(diào)速器處于工作溫度后，如有必要，添加機油。使用表2-1和2-2中給出的信息作為選擇合適潤滑油/液壓油的指南。機油等級的選擇基于調(diào)速器的工作溫度范圍。此外，使用這些信息有助于識別和糾正與Woodward產(chǎn)品中使用的機油相關(guān)的常見問題。對于調(diào)速器與發(fā)動機共用供油的應用，請使用發(fā)動機制造商推薦的機油。調(diào)速器油既是潤滑油又是液壓油。它必須具有允許其在操作溫度范圍內(nèi)運行的粘度指數(shù)，并且必須具有適當?shù)奶砑觿┗旌?，使其在該范圍?nèi)保持穩(wěn)定和可預測。調(diào)速器油必須與密封材料（腈、聚丙烯酸和氟碳化合物）兼容。
Woodward governors are designed to give stable operation with most oils with the viscosity, at the operating temperature, between 50 and 3000 SUS (Saybolt Universal Seconds). At the normal operating temperature, the viscosity should be between 100 to 300 SUS. Poor actuator response or instability may be an indication that the oil viscosity is outside this range. Excessive component wear or seizure in a governor indicates the possibility of: 1. Insufficient lubrication caused by: ? An oil that flows slowly when it is cold, especially during start-up ? No oil in the governor 2. Contaminated oil caused by: 5204-DFNT-PDPMV1? Dirty oil containers ? A governor exposed to heating up and cooling down cycles, which creates condensation of water in the oil 3. Oil not suitable for the operating conditions caused by: ? Changes in ambient temperature
Oil grade selection is based on the operating temperature range of the governor. Also, use this information to aid in recognizing and correcting common problems associated with oil used in Woodward products. For applications where the governor shares the oil supply with the engine, use the oil recommended by the engine manufacturer. Governor oil is both a lubricating oil and a hydraulic oil. It must have a viscosity index that allows it to perform over the operating temperature range, and it must have the proper blending of additives that cause it to remain stable and predictable over this range. Governor oil must be compatible with seal materials (nitrile, polyacrylic, and fluorocarbon). Many automotive and gas engine oils,5204-DFNT-PDPMV1 industrial lubricating oils, and other oils of mineral or synthetic origin meet these requirements.
5204-DFNT-PDPMV1 A center punch mark on an internal stop lever can be viewed through a small panel hole and indicates the minimum speed position of the speed adjusting shaft. The minimum and maximum stop positions are adjustable stop screws with jam nuts. There must be no binding or lost motion in this linkage. Adequate locking methods must be employed on the linkage connections. Oil Supply Use an oil depending on operating temperature for the governor (see Table 2-1). Primary concern is for the oil properties in the governor. Fill the governor with approximately 1.5 US qt (1.4 L) of oil to the mark on the oil sight glass. After the engine is started and the governor is at operating temperature, add oil if necessary.Use the information given in Tables 2-1 and 2-2 as a guide in the selection of a suitable lubricating/hydraulic oil.
