The popular A6ve55 CZPT CZPT Piston Motor
Brueninghaus Hydromatik CZPT A6VE motor
CZPT variable motor A6VE28, A6VE55, A6VE80, A6VE107, A6VE160, A6VE250
| Description |
Open up and shut circuits
Sequence sixty three
Dimensions 28 to 160 nominal pressure four hundred bars and optimum stress 450 bar.
Measurement 250 nominal stress 350 bars and maximum stress four hundred bar.
-Variable plug-in motor with axial tapered piston rotary group of bent-axis layout, for hydrostatic drives in open up and closed circuits
-Much-achieving integration in mechanical gearbox thanks to a recessed mounting flange found on the heart of the situation (incredibly room-preserving development)
-Simple to install, basically plug into the mechanical gearbox (no configuration specifications to be observed)
-Analyzed unit ready to install
-For use particularly in mobile applications
-The displacement can be infinitely altered from Vg max to Vg min = .
-The wide management variety enables the variable motor to fulfill the necessity for large velocity and large torque.
-The output speed is dependent on the stream of the pump and the displacement of the motor.
-The output torque increases with the force differential amongst the large-pressure and lower-strain side and with escalating displacement.

CZPT fluid
Before starting task plHangZhou, please refer to our info sheets RE 95710 (mineral oil), RE 95711 (environmentally suitable hydraulic fluids) and RE 95713 (HF hydraulic fluids) for detailed information relating to the option of hydraulic fluids and problems of use. The A6VE variable displacement plug-in motor is not suited for use with HFA. If HFB, HFC and HFD or environmentally suitable hydraulic fluids are being utilised, the constraints regarding technical knowledge and seals pointed out in RE 95711 and RE 95713 should be observed. If needed, make sure you speak to us to talk about.
Viscosity variety
We advise that a viscosity (at operating temperature) for optimum efficiency and support life purposes of νopt = optimum viscosity 16 to 36 mm2/s be chosen, taken the circulation temperature (shut circuit) and reservoir temperature (open up circuit) into account.
Restrictions of viscosity assortment. The pursuing values utilize in excessive instances:
νmin = five mm2/s
Short-phrase (t < 3 min) at max. permitted temperature of tmax = +115°C. νmax = 1600mm2/s.
Brief-term (t < 3 min) with cold start (p < 30 bar, n ≤ 1000 rpm, tmin = -40°C).
Notice that the maximum hydraulic fluid temperature have to not be exceeded regionally either (e.g. throughout storage). The temperature in the bearing spot is – relying on stress and speed – up to twelve k larger than the average scenario drain temperature.
Special measures are required at temperatures in between -25°C and -40°C. Remember to get in touch with us.
Shaft seal ring
The support life of the shaft seal ring is afflicted by the pace of the motor and the situation drain strain. The permitted loading with intermittent circumstance drain force relies upon on the rotational speed (see chart). Short-term (t < 5 s) pressure spikes of up to 6 bar absolute are permitted.
The regular everlasting case drain force must not exceed three bar complete. The stress in the situation should be equal to or better than the exterior stress on the shaft seal ring.
Flushing and Increase Pressure Valve
The flushing and enhance stress valve is employed to take away heat from the shut circuit and to ensure that a minimum charge force is existing (opening pressure sixteen bar, set notice when location principal valve). A facet result is flushing of the situation.
Heat force fluid is eliminated from the appropriate low pressure side into the motor situation. This is then fed into the reservoir, with each other with the leakage fluid. The strain fluid drawn out of the shut circuit in this way has to be changed by cooled oil that is pumped in by the charge pump. In the open circuit, the flushing and increase pressure valve is utilized solely to flush the scenario from the return line.
The valve is equipped to the variable displacement motor (or built-in into the servo unit, depending on the sort of manage and the measurement).
