IG-FP was formulated to isolate leaks in Down Hole Safety Valve (DHSV) Control Line Compression fittings where the hydraulic fluid is leaking out of the system. Leaking Control Lines can create issues by losing control fluid to the Well bore, the A-Annulus or building up hydraulic pressure in the Tubing Hanger Void.

Research on energy saving system of hydraulic excavator based

These losses are primarily attributed to the back pressure in the excavator''s hydraulic tank and the movement of the piston. The energy transfer efficiency in this process is measured and determined to be 86.39 %. In the energy storage phase, when the boom is storing potential energy, the pressure variation within the TCA is minimal.

Strategies to improve the energy efficiency of hydraulic power

Hydraulic presses (HPs) have been widely used in metal forming process for its smooth transmission, simple control and strong load capacity [1].However, they are famous for their high installed power and poor utilization rate as well [2].Low energy efficiency will not only increase the installed capacity and investment cost, but also lead to excessive oil temperature
