The most important part of a hydraulic system is keeping it clean. Any extreme pressure system is vulnerable to dirt, particles and other matter that contaminate the close tolerances necessary for any hydraulic system. All pipes, fittings, and other components must be extremely clean before use.
When connecting to a hydraulic system, use the tubing or pipe that is capable of handling heavy pressures and loads required by the hydraulic system. Pipes should have a minimum number of bends and fittings, as well as securely fastened and clean. Iron pipes are not recommended because they have particles that will flake off and contaminate a system.
Hydraulic Piston Pumps
When it comes to hydraulic units, you will find that piston pumps, while more expensive than gear and vane pumps, provide longer life operating at higher pressure, with difficult fluids and longer continuous duty cycles. There are several advantages to using a piston pump for operations, particularly in the automotive or aerospace industries. Because of the balanced configuration of the pump, there is virtually no vibration. The piston pump is perfect for several different materials, including those with particularly small particles. In addition, the design itself is very hardy and promotes a long life.
Hydraulic Motors
For most applications, a relatively small hydraulic motor can be placed with ease and connected to a pump located remotely within the system through high-pressure flexible hoses. Initially, axial-piston motors cost more than vane or gear motors of comparable horsepower, and, like radial piston motors, have a long operating life. Because of this, their higher initial cost may not truly reflect the expected overall costs during the life of the equipment.
PSI Repair Services
PSI provides repair services for virtually any hydraulic pump and motor. After the repair, we test the unit, both statically and dynamically, and provide full test reports (testing certificates are also available). When a part proves to be obsolete or beyond repair, our in-house machine shop can reduce costs and create a fast turnaround by manufacturing replacements that meet or exceed OEM specifications. Every year, we find ways to fabricate and salvage parts that OEMs no longer supply or support.
Advanced engineering techniques and full in-house machining capabilities give PSI part-salvaging capabilities unmatched anywhere else in the industry. Next time you face a challenge with a hydraulic component, turn to the pros at PSI.
