Sluggishness

.sg sluggish   .sgs .sluggish

 – Sluggish is an operation where the system moves more slowly than usual. This is a sign of reduced performance and functionality. A loss of speed in the system can be caused by low flow rate and one cause could be due to

• wear and tear in the pumping unit

or

• short circuiting in the system.

The reasons for sluggish operation are-

Hydraulic system:

1. Filter dirty

2. Relief V/V or by pas V/V Leak

3. Ram gland leak

4. Air in the system

5. Oil level low

6. Vane seal leaky

7. Oil temperature high

Pump Problem:

1. Air Lock

2. Single Phasing

3. Piston/cylinder wear

Mechanical Problem:

1. Rudder seized/jammed

2. Water ingress in rudder due to crack

3. Rudder damage

4. Pintle bearing damage

5. Rudder Carrier bearing damage

Control feedback:

1. Linkage loose or slack /loose nut

2. Spring of feedback system failure

3. Controller not tuned properly/faulty settings

4. Pin worn out
