PROSOFT 5205-DFNT-PDPS 網(wǎng)關(guān)模塊
5205-DFNT-PDPS為避免再次污染，更換的機油應(yīng)無污垢、水和其他異物。使用干凈的容器儲存和轉(zhuǎn)移機油。經(jīng)過精心選擇以匹配操作條件并與調(diào)速器部件兼容的機油應(yīng)在更換機油之間提供長期服務(wù)。對于在理想條件下運行的調(diào)速器（最小限度地暴露在灰塵和水下，并在油的溫度限制內(nèi)），可以延長換油時間。如果可用，定期進行機油分析有助于確定機油更換頻率。任何持續(xù)或反復(fù)出現(xiàn)的石油問題都應(yīng)咨詢合格的石油專家進行解決。 5205-DFNT-PDPS建議機油的連續(xù)工作溫度為140至200°F（60至93°C）。環(huán)境溫度限制為–20至+200°F（–29至+93°C）。測量殼體外部下部調(diào)速器的溫度。實際機油溫度將稍微升高，大約升高10°F（6°C）。遵循制造商關(guān)于溶劑使用的說明或限制。如果沒有可用的說明，請小心處理。在通風良好、遠離火源或火花的地方使用清潔溶劑。不遵守上述安全說明可能導(dǎo)致危險火災(zāi)、設(shè)備大面積損壞、人身傷害和/或生命損失。
?油位不當會產(chǎn)生泡沫狀、充氣油。連續(xù)操作調(diào)速器超過油的上限溫度會導(dǎo)致油氧化。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化的油。如果粘度超過50至3000 SUS范圍，則可能導(dǎo)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(dǎo)致設(shè)備大面積損壞、人身傷害和/或生命損失。油表（表2-1）中給出了具體的油粘度建議。選擇一種現(xiàn)成的好品牌的油，無論是礦物油還是合成油，并繼續(xù)使用同一品牌。不要混合不同種類的機油。符合API（美國石油學(xué)會）“S”組或“C”組發(fā)動機服務(wù)分類的機油，從“SA”或“CA”開始，到“SF”和“CD”，適用于調(diào)速器服務(wù)。符合以下規(guī)范性能要求的油也適用： 5205-DFNT-PDPS如果調(diào)速器油受到污染，則應(yīng)更換，如果懷疑會導(dǎo)致調(diào)速器不穩(wěn)定，則應(yīng)進行更換。在油仍然熱且攪拌時排空油，并在重新加注新油之前，用具有一定潤滑質(zhì)量的清潔溶劑（如燃油或煤油）沖洗調(diào)速器。 5205-DFNT-PDPS如果排放時間不足以使溶劑完全排放或蒸發(fā)，則用正在重新加注的相同油沖洗調(diào)速器，以避免稀釋和可能污染新油。
The standard UG Governor serrated drive offers few installation problems. However, the concentricity of the shaft to the drive coupling must be maintained, 5205-DFNT-PDPS and the coupling should be as long as possible to permit greater flexibility and a longer life. A misalignment of the drive shaft can result in a broken drive shaft, causing an overspeed condition or runaway engine. An overspeeding or runaway engine can result in extensive damage to the equipment, personal injury, and/or loss of life. 5205-DFNT-PDPS If an optional keyed drive is used when installing the governor, take care to avoid the following undesirable conditions: ? Rough gear teeth Rough gear teeth or shaft out of round, can cause vibrations which can be transmitted to the governor and cause a jiggle in the governor output shaft. The jiggle can be transmitted to the fuel control, resulting in an undesirable condition. Replace gears if necessary.
To avoid recontamination, 5205-DFNT-PDPS the replacement oil should be free of dirt, water, and other foreign material. Use clean containers to store and transfer oil. Oil that has been carefully selected to match the operating conditions and is compatible with governor components should give long service between oil changes. For governors operating under ideal conditions (minimum exposure to dust and water and within the temperature limits of the oil), oil changes can be extended. If available, 5205-DFNT-PDPS a regularly scheduled oil analysis is helpful in determining the frequency of oil changes. Any persistent or recurring oil problems should be referred to a qualified oil specialist for solution.
? An improper oil level which creates foamy, aerated oil Operating a governor continuously beyond the high-limit temperature of the oil will result in oil oxidation. 5205-DFNT-PDPS This is identified by varnish or sludge deposits on the governor parts. To reduce oil oxidation, lower the actuator operating temperature with a heat exchanger or other means, or change to an oil more oxidationresistant at the operating temperature. A loss of stable governor control and possible prime mover overspeed may result if the viscosity exceeds the 50 to 3000 SUS range. An overspeeding and/or runaway prime mover can result in extensive damage to the equipment, personal injury, and/or loss of life.Specific oil viscosity recommendations are given in the Oil Chart (Table 2-1). Select a readily available good brand of oil, 5205-DFNT-PDPS either mineral or synthetic, and continue using that same brand.
