Fire Resistant Hydraulic Fluid for Coal Mines in the U.S.A.

Abstract

AS A RESULT of a co‐operative effort under the leadership of the U.S. Bureau of Mines, an economic fire‐resistant hydraulic water‐in‐oil fluid for coal mine equipment is claimed to have been evolved. Water‐in‐oil emulsions are relatively new. In this instance, a globule of water is forced into a globule of oil. Being on the outside, the oil furnishes a certain amount of the lubricity required to keep the hydraulic pumps operating properly and economically, because the pumps ordinarily depend for self‐lubrication on the hydraulic fluid being pumped. While such a fluid has been used in industrial machinery with good results, as far as is known, no tests have previously been made under actual coal‐mine operating conditions.
