Abstract: A hydraulic drive assembly for a large pre-existing pressurized digester vessel and a method of installation of the hydraulic drive assembly have been conceived. Such a device includes a stub shaft which has a lower end and an upper end. The lower end engages with a hydraulic drive and the upper end is coupled to a drive shaft. The coupling further includes a top coupling and a bottom coupling. The top coupling is coupled to the drive shaft, and the bottom coupling is coupled to the stub shaft. A drive support bracket is attached to the hydraulic drive and then attached to the drive support bracket by at least one sole plate that is fixed to a foundation. The hydraulic drive assembly installation method is utilized when removing an electric motor and mechanical transmission device and replacing it with a hydraulic drive assembly.

Abstract: This disclosure describes a level indicator assembly for measuring the level of solids in a vessel. The level indicator may desirably comprise a solid shaft extending into a vessel. The shaft may have paddle connected to an interior end of the shaft and an external sensor attached to an exterior end of the shaft. A support structure may engage the sensor to prevent at least a portion of the sensor from moving. By keeping a portion of the sensor stationary, the sensor may measure the change in torsional force exerted on the shaft. By locating the sensor external to the vessel, operators may remove and replace sensors without accessing either the vessel interior or the portions of the level indicator assembly that extend into the vessel.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, that adjust a high-pressure feeder of a feed system used in pulp production based on the fluid leakage through a low-pressure outlet of a high-pressure feeder. Methods can include obtaining multiple flow values, including (1) a make-up liquor flow value, (2) a black liquor flow value, (3) a white liquor flow value, (4) a chip chute circulation flow value, and (5) a high pressure feeder purge flow value. Methods can include determining a chip flow value specifying a flow of chips provided to the high-pressure feeder. Based on the flow values, methods can determine a fluid leakage value specifying an amount of fluid leakage through a gap between a pocket rotor and the housing of the high pressure feeder. Methods can adjust an annular gap based on the fluid leakage value satisfies a threshold leakage value.
