with a high level of wear at underloads. The armature must always travel its full stroke, otherwise the coil will break through. Therefore, there must be no stroke limitation - even when caused by the clogging

losses in pipes are caused by the in the pipe, which consists of friction losses and form-related losses — neither of which are related to pressure. As such, the efficiency of pipe can be expressed as follows:

made between metal strain gauges ( thin foil strain gauge or thick film technology) - which is used the most these days - and semiconductor strain gauges . Metal strain gauges have the advantage of absolute

the output variables of a P-controller, I-controller and a D-controller. P-T1-controller [PT1-controller]: P-controller with P-T2-controller [PT2-controller]: P-controller with 2nd order time delay. These [...] those involving basic transfer elements ( transfer elements ) are the broadest. These include: P-controller [P-controller]: Each control difference ( control deviation ) is allocated a certain value of the [...] sum of the output variables of a P-controller and an I-controller. PD-controller [PD-controller]: The correcting variable is equal to the sum of the output variables of a P-controller and a D-controller.

line cross section and the difference between the (decreasing) accumulator pressure p 1 and the respective load pressure p L: This pressure difference also means a loss of energy (Figure H 25) . Tasks of [...] accumulators and spring accumulators by contrast, the fluid pressure decreases - due to the element applying the load expanding - as the spring characteristic becomes stronger ( hydropneumatic accumulator [...] to perform its allotted task. Pressure difference Δp : Difference between the accumulator pressure at the start and end of volume withdrawal. It depends on the relationship between the gas capacity applying

grooved ring seals with one or two lips ( Figure L 23 ), as well as roof-shaped seals and lip seals — although the latter are not used very often now. Lip seals are generally designed to be undersized or

reservoir is calculated from the temperature difference between the reservoir and the ambiance (To – Ta), form the heat-emitting area A of the reservoir and the heat transfer coefficient U (~11...15 W/(m²·K)

The smaller [...] smaller it is, the smaller the velocity, at which it can still run smoothly. As the friction also depends on the pressure, that too is an influencing factor: the higher it is, the greater the stiction and sliding

drive shaft with one pump as a drive for a second pump ( Figure V 20 ) — in this case both are adjusted using a sum power controller — or a transfer case is used for both pumps, which are then adjusted i

with constant pumps the flow rate not required Q V (Q V = Q 1 – Q N) is fed back to the tank (Figure D 47) . The power converted into heat at the throttling point on the 3-way flow control valve is proportional [...] proportional to the product of Q v and the load pressure p L: With all other methods (that is also with continuously adjustable valves) Q v must be reduced via the pressure-limiting valve , i.e. under full
