Hydraulic System Components

• Many hydraulic systems have a variety of pumps
  that may be manual, electric, or engine driven.
  Some use manual or electric pumps only on the
  ground, while others only use them during
  high-demand situations such as gear retraction or
  during high-speed operations. Regardless of the
  system, a pump is an important component in a
  hydraulic system. Here are some important
  considerations when choosing a pump for your
  hydraulic system.

Hydraulic System Components

• A hydraulic system has several types of flow
  control valves, all of which are used to control
  the fluid flow. These valves control the pressure
  of the system and allow various components to
  function. Some examples of these valves are
  selector valves, sequence valves, priority
  valves, shuttle valves, hydraulic fuses, and
  more. A selector valve controls the direction of
  movement of the hydraulic actuating cylinder and
  provides a path for the return of hydraulic fluid
  to the reservoir.

Filters are used to remove foreign particles

• In order to ensure that your hydraulic system
  remains as efficient as possible, you must
  properly maintain and clean your filter. Foreign
  particles present in your hydraulic fluid may
  cause a number of problems in your system.
  Properly maintained filters will increase the
  mean time between component failures and ensure
  that your machine runs smoothly. This process
  will be illustrated by the flow chart below. You
  will need to evaluate your filtration system to
  determine what components should be cleaned.

Directional control valve

• There are several types of directional control
  valves in a hydraulic system. The types include
  the ball, butterfly, needle, gate, and piston.
  These valves are usually electronically
  controlled, though some models may be operated
  manually. When activated, they allow fluid to
  flow through one side and close off the other.
  They can be used in any number of hydraulic
  applications, from hydraulic pumps to air
  compressors. Read on to learn more about this
  type of valve.

Hydraulic actuator reservoir

• A hydraulic actuator reservoir is an important
  component of a hydraulic system. They serve a
  variety of purposes and are used to store the
  hydraulic fluid when not in use. The hydraulic
  actuator reservoir also acts as a means to
  control the amount of heat transferred and the
  initial force applied to a system. They are also
  used to separate air and moisture from the
  hydraulic fluid, preventing the fluid from
  becoming contaminated. The hydraulic actuator
  reservoir is often part of a machine's body.
