Question 206General Subjects - Assistant Engineer
70% to passTo charge a bladder type hydraulic accumulator _______________.
Aremove all hydraulic system pressure and bring the pneumatic pressure to the system's design pressure
Bincrease the pneumatic pressure until the hydraulic system reaches its design pressure
Cremove all hydraulic system pressure and bring the pneumatic pressure to the accumulator preload pressure
Dallow the accumulator to completely fill with gas charge at atmospheric pressure, shut off the air chamber, and add hydraulic fluid until proper pressure is reached
AI Explanation
The correct answer is C) remove all hydraulic system pressure and bring the pneumatic pressure to the accumulator preload pressure. To charge a bladder-type hydraulic accumulator, you need to remove all hydraulic system pressure and bring the pneumatic pressure to the accumulator's preload pressure, which is the pressure in the gas-filled chamber before any hydraulic fluid is added. This ensures the accumulator is properly pressurized and ready to function as designed. The other options are incorrect because: A) would not bring the pneumatic pressure to the correct preload level, B) would increase the pressure too much, and D) would not properly pressurize the gas chamber first.
