HYDRAULIC CYLINDER PRESSURE TEST
Test procedure
The procedure for conducting the test is as follows:
-
- Secure the cylinder with its service ports up.
- Fill both sides of the cylinder with clean hydraulic fluid through its service ports.
- Connect ball valves (1) and (2), gauges (3) and (4), relief valve (5) and directional control valve (6) as shown in Figure
- 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.
- Position the piston rod mid-stroke and close ball valve (2).
- With the adjustment on the relief valve (5) backed out, direct flow to the rod side of the cylinder.
- Increase the setting of relief valve (5) until the cylinder’s rated pressure is seen on gauge (3).
- 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.
- Record the respective pressure readings on gauges (3) and (4) and monitor any change over time.
