O Testador Automático de Valor de Liberação de Ar HK-0308A está em conformidade com o Método de Teste Padrão ASTM D3427 para Propriedades de Liberação de Ar de Óleos de Petróleo. A agitação do óleo lubrificante com ar em equipamentos, como rolamentos, acoplamentos, engrenagens, bombas e linhas de retorno de óleo, pode produzir uma dispersão de bolhas de ar finamente divididas no óleo. Se o tempo de residência no reservatório for muito curto para permitir que as bolhas de ar subam à superfície do óleo, uma mistura de ar e óleo circulará pelo sistema de óleo lubrificante. Isso pode resultar na incapacidade de manter a pressão do óleo (particularmente em bombas centrífugas), películas de óleo incompletas em rolamentos e engrenagens e baixo desempenho ou falha do sistema hidráulico. Este método de teste mede o tempo que o teor de ar arrastado leva para cair para o valor relativamente baixo de 0,2% em volume sob um conjunto padronizado de condições de teste e, portanto, permite a comparação da capacidade dos óleos de separar o ar arrastado em condições nas quais um tempo de separação está disponível. A importância deste método de teste não foi totalmente estabelecida. No entanto, o ar arrastado pode causar esponjosidade e falta de sensibilidade no controle de turbinas e sistemas hidráulicos. Este teste pode não ser adequado para classificar óleos em aplicações onde os tempos de residência são curtos e os teores de gás são altos.
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.
