Final answer:
The hydraulic pressure for normal operations in a hydraulic system typically ranges from 1000 to 3000 psi. The HSC turns on the secondary pump when the pressure reaches a threshold, which is often set around 2000 psi.
Step-by-step explanation:
The hydraulic pressure for normal operations in a hydraulic system depends on the specific application and equipment being used. However, in most hydraulic systems, the typical operating pressure ranges from 1000 to 3000 pounds per square inch (psi), or 69 to 207 bar. It is important to note that this is a general range and the actual operating pressure can vary based on factors such as the type of fluid being used, the size of the hydraulic components, and the load being lifted.
The HSC (hydraulic sequence controller) in a hydraulic system is designed to turn on the secondary pump when the pressure reaches a certain threshold. This threshold is often set around 2000 psi (138 bar), but it can vary depending on the specific system and equipment.
