Key result
| EQUIPMENT | CONDITION AT START OF WORK | WHAT WAS MEASURED |
|---|---|---|
| ChME-3 locomotive No. 3329, shunting | HPFP in service, worn: element delivery 60–130 ml, spread between elements more than twofold | Delivery of plunger pairs I–VI on the depot shop test bench |
HPFP plunger pair delivery before and after treatment
| PLUNGER PAIR | DELIVERY BEFORE, ml | DELIVERY AFTER, ml | CHANGE |
|---|---|---|---|
| I | 130 | 137 | +5.3 % |
| II | 114 | 232 | +103 % |
| III | 60 | 95 | +58.3 % |
| IV | 118 | 199 | +68.6 % |
| VI | 90 | 208 | +131 % |
Depot shop test bench: 100 rpm, cycle 2 min, conditions before and after identical. The smallest gain is on element I, the least worn one: its delivery before treatment was the highest.
