When securing a steam reciprocating pump, which of the valves listed should remain open?
AI Explanation
The correct answer is B) Steam cylinder drain valve.
When securing a steam reciprocating pump, the steam cylinder drain valve should remain open. This allows any condensation or residual steam to be drained from the steam cylinder, preventing damage to the pump components. The other valves, such as the water cylinder drain valve, steam supply valve, and steam exhaust valve, should be closed to isolate the pump.
The other answer choices are incorrect because the water cylinder drain valve (A) should be closed, the steam supply valve (C) should be closed to stop the flow of steam, and the steam exhaust valve (D) should also be closed to prevent the release of steam.
