Hydraulic accumulators

As a hydraulic accumulator — regardless of the size of the current pressure required = load pressure p L –– is always charged up to the upper operating pressure p 2, during the removal, larger power l

In the case of the accumulator supplies the size of the hydraulic accumulator is determined using the pressure oil requirements of all consumers dependent on the accumulator during a working cycle and

Circuits with the aim of performing a memory action. This is possible in three ways: Memory forms with a lock and dominant activation, i.e. they turn on when both signals for on and off are pending; m

Control whose program is stored in a program memory. The functional elements necessary to process the program and their connections are regarded as factors that cannot be altered. PLCs may be equipped

Special pressure switch valve with the task of switching the constant pump, which charges a hydraulic accumulator , to pressure-free circulation as soon as it reaches its charging pressure and to swit

Filter, which separates contaminations primarily on the inside (bulk) of the filtering material. Filter elements with several layers are used for this and are made of metal powder (sintered filer or f

A newer group of materials between elastomers and thermoplastics : They have the properties of an elastomer up to approximately 70° C (high strength, good elasticity), but react like thermoplastics at

Group of elastic materials, which become soft (thermoelastic) when energy is added (temperature increase), where moulded parts lose their form (voltage). When cooling, plastification of the materials

Process to monitor the operating state of a hydraulic system or individual devices with the aid of temperature and pressure measurements . It uses the hydraulic fluid to carry the information and is b
