FOAMING CHARACTERISTICS OF LUBRICATING OILS ASTM D IP – NFT – ISO

However, the manometer is replaced by a high precision digital pressure controller. Astn channel digital flow control unit, upgrade from rotameter incl.

Novel, sophisticated heating system and control allows the sample to reach test temperature in less than the 60 minutes specified by the method.

Inadequate lubrication, cavitation, and overflow loss of lubricant can lead to mechanical failure.

Both results are automatically displayed on the computer screen. Fan assembly for quicker cooling of Model baths. ASTM D recommends that the diffusers be tested when new and periodically thereafter, preferably after each use.

Historical Version s – view previous versions of standard. It is equipped with a two channel automated sequencer, a two channel mass flow controller, and four temperature probes for the measurement of the sample temperatures.

Air drying tower with Dririte desiccant and stand. The chilled mixture is also helpful for rapid cool down of the air chamber for the next test. Astn channel totalizer installed in Model baths. The automated pressure ramping profile generates the Dynamic Bubble Point pressure that is used to determine Pore Diameter of stainless steel and ceramic diffusers.

Foaming Characteristics: Foam Tester

For specific warning statements, see Sections 78and 9. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: PAO fluid has longer life at higher temperatures then conventional bath medium oils.

ASTM D requires the recertification of the diffuser after 10 foam tests. Available as a stand alone model or incorporated into any of the foam testing baths. Long temperature probes are provided for each of the 4 test positions for digital control and test sample temperature display and precise temperature control during the foaming process.

Furthermore, the traditional analog flow meter is replaced by a digital mass flow meter that directly interacts with the software. This test method is used in the evaluation of oils for such operating conditions.

A touch screen allows the operator selection and full adjustment of all test parameters. Typically ml of solvent is required. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Automatic controller, upgrade, same as FM-9 but specifically to upgrade owners of Lawler Model Model uses a digital indicating 0. Test assembly includes 1 of each: Benefits at a Glance Available as twin-bath arrangement Four test places in each bath Temperature of each bath can be maintained individually Convenient Operation Digitally-indicating circulation thermostats with cooling coil, temperature probe and self-optimizing electronic heating control Borosilicate jars 20 L with leakage protection vessels Test equipment for 2 test places per bath included Customized User Flexibility Different gas diffusers: An automated, two channel sequencer automatically starts the air flow after the 5 minutes soak times, after the 6 minutes stops the air flow and sounds an alarm, and again sounds an alarm after the 10 minutes settling period other times are also available.

PAO fluid has longer life at higher temperatures then conventional bath medium oils. Certified Mott metal cylindrical gas diffuser more uniform air bubbles and greater precision than Norton. Replaces silicones as heated bath medium. Work Item s – proposed revisions of this standard. Especially in high-speed gearing and high-volume pumping systems, the tendency of oils to foam can lead to inadequate lubrication or cavitation which may result in mechanical failure.

Table for air bath with FM chiller. Two channel totalizer installed in Model baths. Specifications subject to change without notice.

A touch screen allows the operator selection and full adjustment of all test parameters. The Autowash is a bench top unit which automatically cleans and dries Mott and Norton diffusers using one or two solvents without removing the air tube. PC controlled apparatus visual first bubble detection. Replaces silicones as heated bath medium. This is calculated by e892 software program. Model 28 ast similar to Model 24 but upgraded for semi automated operation for increased precision and operator assistance.

An automated, two channel sequencer automatically starts the air flow after the 5 minutes soak time, after 5 minutes stops the air flow and sounds an alarm, and again sounds an alarm after the 10 minutes settling period other times are also available.
