Magnetic filter
Filter with a permanent magnetic element for retaining ferromagnetic particles. Magnetic filters are often combined with fleece or screen filters and thereby increase the amount of contamination they
Flow sensor with oval rotor assembly
Volume counter (not a flow rate counter !) based on two oval rotors with special teeth which cause the fluid flow to rotate ( Figure O 12 ). The flow sensor with oval rotor assembly operates with grea
Compression volume ΔVK
Volume which must also be compressed into a space due to the compressibility of a fluid in order to generate a specific pressure there: where V o = volume under pressure, Δ p = pressure increase in th
Form elasticity
Ability of an elastic material to recover its manufactured shape also after elastic deformation. This form elasticity is only retained on thermoelastically processed thermoplastics as long as the defo
Pressure loss through an orifice
The pressure drop Δp at a constriction is calculated from the flow Q, the diameter d of the orifice, the density of the media and the flow coefficient α. The flow coefficient α is depending on the for
Stretch-loading of seals
Stress, which occurs where the moved surface runs together with the sealing lip i.e. the frictional force on the bottom side of the seal acts opposite to the compressive force on the seal (Figure Z 6)
Feed circuit
Low-pressure circuit in a hydrostatic transmission with the task of constantly replacing the small oil volume with fresh oil in a closed circuit. For this purpose, there is a feed circuit from the Cha
Proportional control technology
same mounting dimensions as switching valves. The main advantages of proportional technology are as follows: direction and flow control in a valve, low pressure drop at control edges, mastery of accel
Centrifugal pump
Pump where the increase in energy associated with a medium is largely dependent on the kinetic energy applied to it. For flow rate and pressure , it is a case of: where D = profile diameter, u = circu
