HKL-3427 Air Release Value Tester
Overview
HKL-3427 Air Release Value Tester conforms to the ASTM D3427 standard Test Method for Air Release Properties of Hydrocarbon-Based Oils. It is used to test the ability of turbine, hydraulic, and gear oils to separate entrained air. This apparatus measures the time for 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 turbine and hydraulic systems. This test may not be suitable for ranking oils in applications where residence times are short and gas contents are high.

FAQ
Q1: What standards does this product (HKL-3427 Air Release Value Tester) comply with? What is the applicable scope of the instrument?
A: HKL-3427 Air Release Value Tester conforms to ASTM D3427 Standard Test Method for Air Release Properties of Hydrocarbon-Based Oils. It is used to test the ability of turbine, hydraulic, and gear oils to separate entrained air. This apparatus measures the time for 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 turbine and hydraulic systems. This test may not be suitable for ranking oils in applications where residence times are short and gas contents are high.
Q2: Significance and use of HKL-3427 Air Release Value Tester?
A: Agitation of lubricating oil with air in equipment such as bearings, couplings, gears, pumps, and oil return lines may produce a dispersion of finely divided air bubbles in the oil. If the residence time in the reservoir is too short to allow the air 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), incomplete oil films in bearings and gears, and poor hydraulic system performance or failure.
Q3: What is the minimum order quantity? How long is the delivery lead time?
A: The minimum order quantity is one unit, and delivery is approximately 20 days after advance payment.
Q4: How can I get a product quotation?
A: Please submit your requirements via the contact page on our official website or customer service email, and we will contact you within 24 hours with a detailed quotation.
Q5: Do you offer customized solutions?
A: Yes, we can provide customized instrument configurations and testing solutions based on the customer's specific application need
