Oil-Conversion System

DP710 Patented Preload Hydraulic Pneumatic Booster Pump

Feature

  • A pressure detection features , with machine connection.
  • The most suitable action is not frequent , takes a long time holding pressure of the hydraulic pressure can be maintained.
  • Air outlet pressure of the pump and the pressure is proportional pneumatic output pressure varies according to the adjustment input.
  • We need to follow with different output ( 35 ~ 480 kg / cm 2 ), loop control system of pumping and different flow of different type.
  • Hydraulic output of the set pressure and stop the action, save energy.
  • If the output pressure drops automatically fill pressure, with constant packing features.
  • Preloading type patent design for quick supply and improve efficiency.

Use Precautions

  • During normal operation , the air and power can not be turned off.
  • Hydraulic oil should be every two years or when oil degradation tank , to be replaced.
  • Always check the oil tank of the adequacy of the ( Non-oil meter lower than the "L" lower limit ).
  • For often when replenishing fuel , belongs to an external leak , then check whether the pipeline or external parts have leakage abnormality.
  • Air pneumatic hydraulic pump unit source , should be kept dry to remove water ( Recommended to install air dryer or water filters ) , to prevent damage to the scale or impact of the pump other
