RB Hydraulicweb Tandwielpomp Bookmark: www.hydraulicweb.nl. The Website for everybody who wants to learn about Hydraulics (Fluid Power)

Hydraulic power transmission is one of the oldest forms of power transmission. Modern hydraulics are used for driving a wide range of machines. With the hydraulic technology control of speed, high forces and torques of linear and rotary movements in combination with highly accurate position and velocity control is possible. For manufacturers, users and service technicians of machines with hydraulic technology it is important to gain insight into the fascinating world of hydraulics.

This Technical instruction is a translation and update of the 6-th edition of the very succesfull Dutch version of Hydraulics.

The purpose of this technical training course is:

  • to gain insight in the application and operation of hydraulic systems;
  • to learn how to read a hydraulic diagram (functional thinking), the graphical symbols are according to ISO 1219-1.
  • to gain insight into the function and operation of the components;
  • to gain insight in the relation between the components in a hydraulic system, the so called 'system technology'.

Included are topics such as pump control (pressure and load sensing control), proportional and servo hydraulics.

More than 75% of failures in hydraulic systems are directly or indirectly the result of improper or inadequate conditioning. So conditioning of the system and contamination control are very important in relation to the downtime and lifetime of an installation. This issue is discussed in the chapter 'conditioning'.
