During startup, it is common for intensifiers to peak and change between pressures. But during normal operation, it should work smoothly to the left-right way at the same speed. However, if the hydraulic piston travels faster too much in one or both directions than the pump can support and an alarm will be heard.
If over stroking is happened, your first step is to reset the alarm and then:
- Cutting heads turn off
- The pump turns on and gives time to build up pressure
- Cutting heads turn on
- Intensifier stroke rate monitor either by manually or by operator surface indicator.
