CZPT A6ve sequence CZPT Piston Motor widely utilized
Brueninghaus Hydromatik CZPT A6VE motor
CZPT variable motor A6VE28, A6VE55, A6VE80, A6VE107, A6VE160, A6VE250
Description |
Open and shut circuits
Series 63
Measurement 28 to 160 nominal stress four hundred bars and optimum pressure 450 bar.
Size 250 nominal pressure 350 bars and optimum stress 400 bar.
-Variable plug-in motor with axial tapered piston rotary team of bent-axis layout, for hydrostatic drives in open and closed circuits
-Much-reaching integration in mechanical gearbox owing to a recessed mounting flange found on the middle of the case (very room-preserving building)
-Effortless to install, just plug into the mechanical gearbox (no configuration specifications to be observed)
-Tested unit completely ready to put in
-For use especially in mobile programs
-The displacement can be infinitely changed from Vg max to Vg min = .
-The wide control assortment permits the variable motor to satisfy the necessity for substantial speed and higher torque.
-The output pace is dependent on the flow of the pump and the displacement of the motor.
-The output torque will increase with the pressure differential amongst the large-stress and lower-pressure side and with growing displacement.

CZPT fluid
Ahead of starting undertaking plHangZhou, please refer to our data sheets RE 95710 (mineral oil), RE 95711 (environmentally satisfactory hydraulic fluids) and RE 95713 (HF hydraulic fluids) for in depth information relating to the selection of hydraulic fluids and situations of use. The A6VE variable displacement plug-in motor is not suitable for use with HFA. If HFB, HFC and HFD or environmentally acceptable hydraulic fluids are getting utilised, the constraints with regards to specialized information and seals pointed out in RE 95711 and RE 95713 should be noticed. If essential, remember to speak to us to discuss.
Viscosity range
We suggest that a viscosity (at working temperature) for the best possible efficiency and service daily life functions of νopt = optimum viscosity sixteen to 36 mm2/s be chosen, taken the circulation temperature (closed circuit) and reservoir temperature (open circuit) into account.
Boundaries of viscosity selection. The subsequent values use in severe cases:
νmin = five mm2/s
Quick-expression (t < 3 min) at max. permitted temperature of tmax = +115°C. νmax = 1600mm2/s.
Limited-phrase (t < 3 min) with cold start (p < 30 bar, n ≤ 1000 rpm, tmin = -40°C).
Be aware that the maximum hydraulic fluid temperature must not be exceeded regionally either (e.g. for the duration of storage). The temperature in the bearing area is – depending on stress and speed – up to 12 k increased than the common scenario drain temperature.
Particular actions are necessary at temperatures among -25°C and -40°C. Remember to speak to us.
Shaft seal ring
The support life of the shaft seal ring is influenced by the speed of the motor and the circumstance drain strain. The permitted loading with intermittent situation drain strain depends on the rotational velocity (see chart). Brief-term (t < 5 s) pressure spikes of up to 6 bar absolute are permitted.
The typical long term case drain pressure have to not exceed three bar complete. The strain in the circumstance have to be equivalent to or increased than the exterior force on the shaft seal ring.
Flushing and Improve Stress Valve
The flushing and improve strain valve is utilized to get rid of warmth from the closed circuit and to make sure that a minimum charge strain is present (opening force sixteen bar, set observe when placing major valve). A aspect influence is flushing of the scenario.
Warm strain fluid is removed from the relevant low pressure aspect into the motor case. This is then fed into the reservoir, with each other with the leakage fluid. The pressure fluid drawn out of the shut circuit in this way has to be changed by cooled oil that is pumped in by the cost pump. In the open circuit, the flushing and boost stress valve is used solely to flush the case from the return line.
The valve is fitted to the variable displacement motor (or built-in into the servo device, dependent on the type of handle and the dimension).
