Abstract
Described is an apparatus and a method to accurately determine the gas entrainment characteristics of liquids, such as automatic transmission fluids. The apparatus comprises a liquid reservoir, a conduit having an inlet and an outlet connected to the liquid reservoir so as to form a pressurized recirculating loop for the liquid in the liquid reservoir, a pump for moving the liquid through the conduit, and a means for admitting gas (such as air) into the conduit to aerate the liquid.
Claims17
An apparatus for determining the gas entrainment characteristic of a liquid comprising:
- a liquid reservoir;
- a conduit having an inlet and two outlets connected to the liquid reservoir so as to form a recirculating loop for the liquid in the liquid reservoir, wherein the first outlet discharges liquid above the surface of the liquid in the liquid reservoir, and the second outlet discharges liquid below the surface of the liquid in the liquid reservoir immediately next to the inlet of the conduit;
- a pump for moving the liquid through the conduit;
- and
- a means for admitting gas into the conduit.
A method for determining the gas entrainment characteristics of a liquid comprising,
- recirculating the liquid from a reservoir through a conduit by a pump, wherein the conduit has an inlet and two outlets connected to the liquid reservoir so as to form a recirculating loop for the liquid in the liquid reservoir, wherein the first outlet discharges liquid above the surface of the liquid in the liquid reservoir, and the second outlet discharges liquid below the surface of the liquid in the liquid reservoir immediately next to the inlet of the conduit;
- injecting gas into the conduit to mix with the recirculating liquid;
- and
- sampling the liquid.
