Google Patents US1928122A - Flexible stuffing box assembly This requires a stuffing box arrangement with three separate passages, each of which must be sealed against the other.US1928122A - Flexible stuffing box assembly When an air clutch is located on each end of the drum shaft and water cooled brake flanges are used, it is necessary to provide an air inlet as well as a water inlet and outlet at one end of the drum shaft. Air clutches are commonly used on the drum shaft of modern hoists or drawworks which necessitates the introduction of compressed air to the drum shaft for actuating the clutches. The most convenient arrangement for cooling the brake flanges is to introduce water through drilled passages in the end of the drum shaft, and circulate it through jackets on the inner surfaces of the brake flanges. In all oil field hoists or drawworks for heavy duty drilling below 5,000 feet, it is desirable to provide water cooled brake flanges for the hoisting unit to prevent overheating of the brakes under heavy loads which cause a large amount of wear on the brake flanges and lining, thus requiring frequent replacement of the parts. This invention relates to a stuffing box and more particularly to an air and water stuffing box for use on the drum shaft of a hoist. ![]() ![]() ![]() HT 3196 i-FRAME Water Pump pdf manual download.
