Parallel intensifiers Opposed twin Intensifiers

TECHNOLOGY

Power drive Pump Electric Servo Pump

Advantages parallel intensifiers:

-Constant pressure signal = high quality cut- Redundancy (can run with only 2 intensifiers and do the any maintenance when you decide not when the machine breaks down)- No attenuator to be replaced.- Low Cycle time: 30 cycle/minute = Long time between replacement (all things equal there is less wear per hour with 3 intensifiers = longer time between seal replacement)- Air/oil heat exchanger (integrated)

PARALLEL INTENSIFIER

Disadvantages opposed twin intensifiers

- Pressure drops = less quality- No redundancy (production at the mercy of breakdowns)- Attenuator needed (reservoir) that has to be replaced (€ 5.000/10.000)- High Cycle time: 60 cycle/minute = High maintenance costs- Water/oil heat exchanger

OPPOSED TWIN INTENSIFIER

POWER DRIVE PUMP

Disadvantages pd intensifiers

- Ultre High Cycle time: 300 cycle/minute = Ultra High maintenance costs due to the high speed and temperature- Working pressure: maximum pressure of 3800 bar = less cutting speed/quality- No redundancy (production at the mercy of breakdowns)- Pump flowrate fixed = high water consumption (water is consumed also when the head is closed)- Intensifier normally used for hydro cleaning applications = low cost, low pressure, low speed

Disadvantages electric servo pump

-High Cycle time: 60 cycle/minute = High maintenance costs due to the high speed and temperature- Working pressure: maximum pressure of 3800 bar = less cutting speed/quality- No redundancy (production at the mercy of breakdowns)- Attenuator needed (reservoir) that has to be replaced (€ 5.000/10.000)- New technology: how many pump Techni already installed?
