HYDRAULIC CYLINDER PRESSURE TEST  

Test procedure

The procedure for conducting the test is as follows:

1. 1.  Secure the cylinder with its service ports up.
   2.  Fill both sides of the cylinder with clean hydraulic fluid through its service ports.
   3. Connect ball valves (1) and (2), gauges (3) and (4), relief valve (5) and directional control valve (6) as shown in Figure 
   4. With ball valves (1) and (2) open, stroke the cylinder using the directional control valve (6) multiple times to remove all remaining air from both sides of the cylinder – take care not to ‘diesel’ the cylinder.
   5. Position the piston rod mid-stroke and close ball valve (2).
   6. With the adjustment on the relief valve (5) backed out, direct flow to the rod side of the cylinder.
   7. Increase the setting of relief valve (5) until the cylinder’s rated pressure is seen on gauge (3).
   8. Close ball valve (1) and center directional control valve (6). Note: it is assumed that the hydraulic power unit used to conduct the test has its own over-pressure protection – not shown in Figure 1.
   9. Record the respective pressure readings on gauges (3) and (4) and monitor any change over time.
