IE B035AS AKRONTO · REPORT ON TREATMENT OF A HYDRAULIC POWER UNIT
BEAVER III power unit: working pressure raised with no teardown, in service
Hydraulic system pressure rose, the pump returned to working pressure, the station remained in operation. 20 % — working pressure of the power unit under load, 100 → 120 bar; 1 bar — pressure on the pump working gauge, 0 → 1 bar (2002).

Key results
| EQUIPMENT | CONDITION AT START OF WORK | WHAT WAS MEASURED |
|---|---|---|
| JSB BEAVER III power unit | Pressure 100 bar against a rating of 138 bar | Working pressure of the hydraulic system |
| Hydraulically driven water pump | Moved water but built no working pressure — 0 bar | Pressure on the pump working gauge |
Power unit — working pressure of the hydraulic system
| PARAMETER | BEFORE TREATMENT | AFTER 24 h OF OPERATION |
|---|---|---|
| Working pressure of the power unit | 100 bar | 120 bar |
| Share of the rated pressure of 138 bar | 72 % | 87 % |
Measured under working load: the power unit was driving the hydraulically driven water pump. The rated pressure of 138 bar is stated in the report itself.
Working tool — hydraulically driven water pump
| TREATMENT STAGE | PRESSURE ON THE PUMP WORKING GAUGE |
|---|---|
| Before treatment | 0 bar |
| After 8 h of operation following the first tube | 0.5 bar |
| After the second tube was introduced | 1 bar |
Before the treatment the pump was unfit for its intended duty: it moved water but built no working pressure at all.
