ABSTRACT:
In a brake system for a boiler feed water pump wherein a flat-sided brake disc is mounted on a rotating shaft, arms are hingedly mounted on a base frame at the lower end of each arm, the arms being positioned at diametrically opposite sides of the disc, the base frame extending between the lower ends of the arms, calipers are mounted on the arms to embrace diametrically opposite areas of the sides of the disc. A yoke is mounted on the upper ends of the arms in such a way as to be easily dismounted. The yoke is conventional. When it is desired to repair the calipers or to remove one of the shafts upon which the brake disc is mounted or with which it is integral, with the shaft and disc not rotating, as when the unit is out of service, it is only necessary to remove the yoke, and swing the arms out away from the disc. The brakes can easily be inspected and repaired, as well. The brakes are actuated by an intensifier system, in which an intensifier is connected to a valve which is connected to a reservoir. When the valve is opened, the pressure in the hydraulic line to the brake is monitored, and if it is below the desired pressure, the intensifier is caused to repeat, to pull hydraulic fluid into the intensifier, hence to the brake line, and to the brake calipers, causing the calipers to brake the disc and shaft to a stop, and to hold it stopped indefinitely.
