HK-0308A Otomatik Hava Tahliye Değeri Test Cihazı, Petrol Yağlarının Hava Tahliye Özellikleri için ASTM D3427 Standart Test Yöntemi'ne uygundur. Yataklar, kaplinler, dişliler, pompalar ve yağ geri dönüş hatları gibi ekipmanlarda yağlayıcı yağın hava ile karıştırılması, yağda ince bölünmüş hava kabarcıklarının dağılmasına neden olabilir. Haznedeki kalış süresi, hava kabarcıklarının yağ yüzeyine çıkmasına izin vermeyecek kadar kısaysa, yağlayıcı yağ sisteminde hava ve yağ karışımı dolaşır. Bu durum, yağ basıncının korunamamasına (özellikle santrifüj pompalarda), yataklarda ve dişlilerde eksik yağ filmlerine ve zayıf hidrolik sistem performansına veya arızasına neden olabilir. Bu test yöntemi, standartlaştırılmış bir test koşulları kümesi altında, sürüklenen hava içeriğinin hacimce nispeten düşük bir değer olan %0,2'ye düşme süresini ölçer ve böylece yağların, ayırma süresinin mevcut olduğu koşullar altında sürüklenen havayı ayırma kabiliyetlerinin karşılaştırılmasına olanak tanır. Bu test yönteminin önemi henüz tam olarak ortaya konmamıştır. Ancak, sürüklenen hava, süngerimsi bir yapıya ve türbin ve hidrolik sistemlerin kontrolünde hassasiyet kaybına neden olabilir. Bu test, kalış sürelerinin kısa ve gaz içeriklerinin yüksek olduğu uygulamalarda yağların derecelendirilmesi için uygun olmayabilir.
Overview
HK-0308A Automatic Air Release Value Tester conforms to ASTM D3427 Standard Test Method for Air Release Properties of Petroleum Oils. Agitation of Lubricating oil with air in equipment，such as bearings, couplings, gears， pumps, and oil reture lines， may produce a dispersion of finely divide air bubbles in the oil. If the residence time in the reservoir is too short to allow the aire bubbles to rise to the oil surface, a mixture of air and oil will circulate through the lubricating oil system. This may result in an inability to maintain oil pressure (particularly with centrifugal pumps), imcomplete oil films in bearings and gears, and poor hydraulic system performance or failure.
This test method measures the time of the entrained air content to fall to the relatively low value of 0.2% volume under a standardized set of test conditions and hence permits the comparison of the ability of oils to separate entrained air under conditions where a separation time is available. The significance of this test method has not been fully established. However, entrained air can cause sponginess and lack of sensitivity of the control of turbin and hydraulic systems. This test may not be suitable for ranking oils in applications where residence times are short and gas contents are high.
