Seta Autowash Part Number 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.
Conventional bath fluids darken and require frequent replacement. One channel totalizer installed in Model baths. Inadequate lubrication, cavitation, and overflow loss of lubricant can lead to mechanical failure. Once you start a programme you can leave the Autowash unattended and the instrument sounds an audible warning when the cycle has finished.
Certified Mott metal cylindrical gas diffuser more uniform air bubbles and greater precision than Norton.
Foaming Characteristics of Lubricating Oils – ASTM D, D | Lawler Manufacturing
The automated pressure ramping profile generates the Dynamic Bubble Point pressure that is used to determine Pore Diameter of stainless steel and ceramic diffusers. This is calculated by the software program. PAO fluid has longer life at higher temperatures then conventional bath medium oils.
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. Test assembly includes 1 of each: Model 24 dual foam test bath is the traditional arrangement with two glass jars mounted on a supporting base.
Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: Flat bottomed glass mL graduated test cylinder starting at 10mL and continuing at 10mL increments.
The use of heated air to heat the test samples improves the overall safety by eliminating the use of the potentially unsafe, smoking, dripping of, flammable, hot liquid bath medium. Two channel totalizer installed in Model baths. Replaces silicones as heated bath medium. For specific warning statements, see Sections 78and 9. Click for Software Screen. A touch screen allows the operator selection and full adjustment of all test parameters.
The foam tester allows the determination of the foaming characteristics of lubricating oils at specific temperatures by empirically rating the foaming tendency and the foam stability.
Fan assembly for quicker cooling of Model baths. Sealing washer for between inlet tube and diffuser. Also displayed is the time remaining to the next test event requiring operator attention. Two channel digital flow control unit, upgrade from rotameter incl. D82 cooler used with Model 24 and 28 liquid baths. All key parameters are displayed during the test. The chilled mixture is also helpful for rapid cool down of the air chamber for the next test.
Test assembly includes 1 of each: Work Item s – proposed revisions of this standard. Furthermore, the traditional analog flow meter is replaced by a atm mass flow meter that directly interacts with the software.
Even low levels 1 ppm and above of silicone contamination interfere with test results.
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.
Means of empirically rating the foaming tendency and the stability of the foam are described. Automatic controller, upgrade, same as FM-9 but specifically to upgrade owners of Lawler Model Also displayed is the time remaining to the next test event requiring operator attention.
For improved consistency of results, two digital indicating mass flow controllers are used for precisely measuring and controlling the amount of air delivered to the air diffuser.
Copyright Stanhope—Seta Limited Four position sample storage rack cylinders not included. Novel, sophisticated heating system and control allows the sample to reach test temperature in less than the 60 minutes specified by the method. 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: Silicone fluids are not recommended.
ASTM D requires 8d92 recertification of the diffuser after 10 foam tests.
