Resistance to flow

Here's another Flint Hydraulics Tech Tip: If a faucet is partially closed, it resists flow by forcing all the flow to pass through a smaller opening. A gauge upstream of the faucet inlet will show an increase of pressure. Closing the faucet a bit will not necessarily reduce the flow rate out of the faucet. If there is no other flow path, the pressure will rise to the level required to push the full flow rate through the smaller opening. Need help troubleshooting?

Pressure inversely proportional to piston area

Here's another Flint Hydraulics Tech Tip: Two cylinders each independently lifting equal weight loads will not develop identical pressures unless the cylinders' piston areas are equal. For example, a 5-inch diameter cylinder raising a 50,000 pound load will develop 2,545.82 PSI, but a 2.5-inch bore diameter cylinder will have pressure of 10,187.44 PSI.

Load resistance & pressure in a hydraulic system

Here’s another Flint Hydraulics Tech Tip: Load resistance is one of the main sources of pressure in a hydraulic system. How high will the pressure rise? Just as a horse will not pull any harder than required to move a load, similarly, hydraulic pressure will rise no higher than is necessary to move a load. Need help troubleshooting your system?

Output power from a hydraulic system

Here's another Flint Hydraulics Tech Tip: The output power from a hydraulic system cannot increase if the input power to the hydraulic system does not increase. In other words, the power capability of any hydraulic system is limited by the available power from the engine or electric motor that drives the pump. Additionally, although the engine may have power to spare, an increase in hydraulic system output power depends not only on engine power capability but also on the ability of the hydraulic system to transmit power from the engine.

Hydraulic transmission system

If a hydraulic system is not a source of power, what is it? Hydraulics is defined as: The means of transmitting power through pressure applied on a confined liquid. The key word here is transmitting. A hydraulic system is a transmission system; its function is the same as that of the transmission in a car – to transmit the power output of the prime mover so the power can be used to do work.  It is important to note that it is not only the hydraulic pump that is the “transmission;” every component of the hydraulic system is part of a transmission system. A hydraulic system can deliver to the machine no more power than the amount of power put into the hydraulic pump by the engine, and an improperly designed hydraulic system can significantly reduce the power delivered to the working parts of a machine.

Pressure in a Hydraulic System

Here's another Flint Hydraulics Tech Tip: Fluids always follow the path of least resistance. If your hydraulic system cannot develop sufficient pressure to operate your machine, and if you're sure the pump is sound, there is a defect in your system flow path. Troubleshooting can be time-consuming and frustrating, but it's more effective than replacing expensive parts that aren't causing the problem.
