A6ve107 CZPT CZPT Piston Motor extensively utilized
Brueninghaus Hydromatik CZPT A6VE motor
CZPT variable motor A6VE28, A6VE55, A6VE80, A6VE107, A6VE160, A6VE250
Open and shut circuits
Sequence sixty three
Dimension 28 to a hundred and sixty nominal pressure 400 bars and optimum pressure 450 bar.
Dimensions 250 nominal force 350 bars and maximum strain 400 bar.
-Variable plug-in motor with axial tapered piston rotary group of bent-axis design, for hydrostatic drives in open up and shut circuits
-Significantly-reaching integration in mechanical gearbox because of to a recessed mounting flange found on the heart of the case (extremely place-preserving building)
-Simple to set up, basically plug into the mechanical gearbox (no configuration specifications to be observed)
-Analyzed device completely ready to set up
-For use specially in mobile programs
-The displacement can be infinitely transformed from Vg max to Vg min = .
-The extensive control selection allows the variable motor to satisfy the prerequisite for substantial pace and high torque.
-The output pace is dependent on the flow of the pump and the displacement of the motor.
-The output torque boosts with the pressure differential in between the large-stress and low-stress aspect and with growing displacement.

Ahead of starting project plHangCZPT, remember to refer to our information sheets RE 95710 (mineral oil), RE 95711 (environmentally suitable hydraulic fluids) and RE 95713 (HF hydraulic fluids) for in depth information with regards to the choice of hydraulic fluids and situations of use. The A6VE variable displacement plug-in motor is not appropriate for use with HFA. If HFB, HFC and HFD or environmentally satisfactory hydraulic fluids are currently being utilized, the constraints concerning specialized knowledge and seals described in RE 95711 and RE 95713 have to be observed. If needed, make sure you make contact with us to discuss.
We advocate that a viscosity (at working temperature) for optimum effectiveness and provider life reasons of νopt = the best possible viscosity 16 to 36 mm2/s be decided on, taken the circulation temperature (shut circuit) and reservoir temperature (open circuit) into account.
Boundaries of viscosity variety. The pursuing values use in extreme cases:
νmin = 5 mm2/s
Quick-phrase (t < 3 min) at max. permitted temperature of tmax = +115°C. νmax = 1600mm2/s.
Quick-phrase (t < 3 min) with cold start (p < 30 bar, n ≤ 1000 rpm, tmin = -40°C).
Notice that the highest hydraulic fluid temperature need to not be exceeded regionally either (e.g. in the course of storage). The temperature in the bearing spot is – based on pressure and velocity – up to 12 k greater than the typical scenario drain temperature.
CZPT actions are required at temperatures among -25°C and -40°C. Remember to make contact with us.
Shaft seal ring
The services lifestyle of the shaft seal ring is impacted by the velocity of the motor and the situation drain strain. The permitted loading with intermittent case drain pressure relies upon on the rotational velocity (see chart). Quick-time period (t < 5 s) pressure spikes of up to 6 bar absolute are permitted.
The regular long term case drain force should not exceed 3 bar absolute. The pressure in the case need to be equivalent to or increased than the external pressure on the shaft seal ring.
Flushing and Increase Pressure Valve
The flushing and boost strain valve is utilized to remove heat from the closed circuit and to make sure that a bare minimum charge strain is current (opening strain sixteen bar, set note when location main valve). A facet effect is flushing of the case.
Heat force fluid is taken off from the related minimal pressure facet into the motor case. This is then fed into the reservoir, collectively with the leakage fluid. The stress fluid drawn out of the shut circuit in this way has to be replaced by cooled oil that is pumped in by the cost pump. In the open circuit, the flushing and increase strain valve is utilised entirely to flush the situation from the return line.
The valve is equipped to the variable displacement motor (or integrated into the servo unit, depending on the variety of control and the dimensions).
