In fill-in-the-blank questions, the flow rate of a steam pump is regulated by adjusting the （） valve, thereby increasing or decreasing the pump’s （） to raise or lower the flow rate. Answers: main steam valve, number of reciprocations. Correct answer: +2; In-depth discussion: +5
The flow regulation of a steam pump is mainly achieved by adjusting the (steam inlet) valve, thereby increasing or decreasing the pump’s flow rate to raise or lower the flow volume
The flow regulation of a steam pump is mainly achieved by adjusting the (main steam) valve, thereby increasing or decreasing the number of reciprocations of the pump to increase or decrease the flow rate.
The flow regulation of a steam pump is mainly achieved by adjusting the (intake) valve, thereby increasing or decreasing the pump’s (piston stroke) to increase or decrease the flow rate.
The flow regulation of a steam pump is mainly achieved by adjusting the (exit) valve, thereby increasing or decreasing the pump’s (pressure) to increase or decrease the flow rate
