The first step when resetting the slide valves on a duplex reciprocating pump is to _______________.
AI Explanation
The correct answer is B) place the steam pistons in the mid-stroke position.
When resetting the slide valves on a duplex reciprocating pump, the first step is to position the steam pistons at the mid-stroke position. This ensures that the slide valves are centered and can be easily adjusted without interfering with the piston movement. Placing the pistons at the mid-stroke position allows for the most accessible access to the slide valves, making the resetting process more straightforward.
The other options are incorrect because: A) positioning the pistons at 3/4 stroke does not provide the optimal access for resetting the slide valves; C) ensuring the balance piston is on the down stroke is not the first step in the process; and D) measuring the current port openings is not necessary before resetting the slide valves, as the goal is to return the valves to their original configuration.
