What reading level is Hydraulic Elevators Their Design Construction Operation Care And Management book?
To quickly assess the difficulty of the text, read a short excerpt:
If it is desired to run the car down, the valve D is closed and the valve A is opened; then the water - FIG. 197 FIG. 198 from the lifting-cylinder pipe will escape into the discharge pipe and through it to the pressure tank. The car can also be run down by open- ing the valve B with A either open or closed ; the speed will be greater if B is opened. It is not actually necessary to close the valve D in coming down. From the foregoing it will be noticed that when the safe pump is used to lift an... extra heavy load, the main operating valve is not used ; in fact it is cut out of service by the closing of the valve C, and the move- ment of the car is controlled entirely by the hand valves A, B and D.
While the diagram, Fig. 196, shows very well the general arrange- ment of the high-pressure system with only one elevator, it leaves con- siderable to the imagination when one considers an extensive plant con- taining a large number of elevators and a corresponding number of pumps and accumulators.
