1. A weight-loaded accumulator:

  1. loses pressure as fluid discharges
  2. gains pressure as fluid discharges
  3. stays at the same pressure as fluid discharges

2. A spring-loaded accumulator:

  1. loses pressure as fluid discharges
  2. gains pressure as fluid discharges
  3. stays at the same pressure as fluid discharges

3. Gas charged accumulators use:

  1. oxygen
  2. nitrogen
  3. argon

4. The most common accumulator application is:

  1. supplementing pump flow
  2. making up for system leaks
  3. providing an emergency power supply

5. Precharge pressure should be checked at least every:

  1. one to two months
  2. two to three months
  3. three to six months

6. An accumulator may be used to:

  1. make a pump run faster
  2. make a valve shift more quickly
  3. make up for system leaks

7. Accumulator pre-charge pressure is normally.

  1. 95% of minimum system pressure
  2. 85% of minimum system pressure
  3. 75% of minimum system pressure

8. When the pump is running, an accumulator dump valve keeps fluid:

  1. from going to the accumulator
  2. from going to the circuit
  3. from going to tank

9. An unloading relief valve sends:

  1. pump flow to tank at system pressure
  2. accumulator flow to tank at system pressure
  3. pump flow to tank at 25 to100 psi

10. This symbol represents a:

  1. weight-loaded accumulator
  2. gas-charged accumulator
  3. spring-loaded accumulator
