Basic Pneumatics (GLMN00899) Questions and Answers Already Passed What is the role of an intercooler in a two-stage compressor system? To decrease the amount of power required to operate the compressor What is the benefit of unloading a compressor? It allows the compressor to operate without producing air What type of pneumatic cylinder uses an internal spring for returning the piston? Single-acting, single-rod How does the spool in a valve regulate airflow, and how does it move in a high-pressure system? The spool shifts by sliding from one position to another and is designed to move easily in high-pressure systems What happens to the speed and pressure of air when it flows through a pipe that narrows? The speed of the air increases, while its pressure decreases 2 What are the functions of lubricating oil in a compressor? To minimize friction between moving parts and enhance the cooling of the compressor How is the cracking pressure of a basic poppet-style relief valve adjusted? By adjusting the spring tension What is the sole function of a pressure-relief valve? To safeguard the system from damage How does the thrust capacity compare when a single-rod, double-acting pneumatic cylinder's rod is extending versus retracting? The thrust when extending is greater than when retracting Why does water tend to accumulate in a pneumatic system? Because the moisture capacity of the air decreases when compressed What is the typical operating speed range for rotary-screw compressors? 3 Between 3,000 and 12,000 rpm When installing a pipe for compressor discharge, what should the slope be, and how should it be measured? The pipe should slope downward
