Understanding Power Fluid Schematics

If you’re hoping to learn more about the interesting and exciting world of pneumatic components in Minnesota, you’ll likely encounter a challenging schematic. Without proper experience or a highly specialized base of knowledge, power fluid schematics can seem nearly impossible to read. The ability to read a fluid schematic is essential, however, if you’re hoping to learn more about the way that your hydraulic gear operates and is repaired.

Hydraulic schematics can look mystifying at first glance, which is why it’s so exceptionally important for people to possess an understanding of the symbolism behind the schematics. Here are just some of the symbols behind power fluid schematics:

  • Pumps: On power fluid schematics, there are two primary types of pumps indicated: hydraulic and pneumatic. Pumps are indicated as a circle with one or more arrowheads. Hydraulic pumps are indicated using a solid arrowhead, whereas pneumatic compressors are indicated with hollow arrowheads. The arrowheads indicate the direction of flow in the schematic.
  • Piping: Piping is arguably the most significant part of any fluid schematic system. Piping transports the working media from one point to another. An even, straight line indicates a working line; a line with a single break in the middle indicates a pilot line. A dotted line indicates a drain line, while a single black dot indicates a connector. A bowed line between two connectors indicates a flexible line, while a line with an “x” at the end indicates a plug.
  • Reservoirs: Reservoirs are where the working media is stored in a fluid system. Because there are a number of different types of reservoirs capable of holding compressed gas or hydraulic fluid, there are a number of different symbols used to indicate reservoirs. There are some universal conventions, however. A hollow rectangle without a top line indicates an open reservoir; a closed hollow rectangle indicates a pressurized reservoir.
  • Valves: Because valves are one of the most important and dynamic pneumatic components in Minnesota, the way that they are presented on power fluid schematics is especially complex. Most valve indicators will appear to be a cutaway of an actual valve system, including cylinders, pressure inlets and exhaust piping.
  • Actuators: The actuator is the component of the hydraulic system that converts the hydraulic or pneumatic pressure into mechanical energy. There are two primary types of actuators used: linear actuators and rotary actuators. Linear actuators are usually illustrated in a way that shows their piston; rotary actuators appear identical to pumps except for the fact that the tail of their arrow touches the interior wall of the circle, rather than the point.
