Lube-Tips - Best Way To Eliminate Hydraulic Oil Leakage


 
One drop of oil that drips once per second will result in a loss of 405 gallons in a year’s time. At the cost of $9 per gallon, that one leak costs $3,645 in one year.
Here 3 ways to eliminate the oil leakage:
 
1. SHOCK SUPPRESSOR
• The suppressor is pre-charged with dry nitrogen. The recommended pre-charge of nitrogen is half the maximum system pressure.
• The suppressor should be installed as close as possible to where the shock is occurring.
 
2. SYSTEM PIPING AND HOSES
• Eliminate the use of 90-degree fittings in the pipe and tubing because at 90-degree turns it creates turbulence and shock generated thus causing leakage.
• Clamps should be spaced every 5-8 feet and within 6 inches of the termination point.
• A hose should be installed at the outlet of the pump prior to entering the manifold or main header, this will reduce shock when oil flow rapidly.
• The length of the hose installed should be in the right length.
 
3. PRESSURE SETTINGS
•The maximum pressure limiter in the system should be set 200 psi higher than the pressure required to move the load. If the pressure is set higher than that, excessive shock will be generated when starting and stopping the actuator.
