Description
Weight (approx.)m kg 16 26 34 47 64 90 Hydraulic fluid
Before starting project planning, please refer to our data sheets RE 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids) and RE 90223 (HF hydraulic fluids) for detailed information regarding the choice of hydraulic fluids and conditions 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 being used, the constraints regarding technical data and seals mentioned in RE 90221 and RE 90223 must be observed. If necessary, please contact us to discuss.
Viscosity range
We recommend that a viscosity (at operating temperature) for optimum efficiency and service life purposes of νopt = optimum viscosity 16 to 36 mm2/s be chosen, taken the circulation temperature (closed circuit) and reservoir temperature (open circuit) into account.
Limits of viscosity range. The following values apply in extreme cases:
νmin = 5 mm2/s
Short-term (t < 3 min) at max. permitted temperature of tmax = +115°C. νmax = 1600mm2/s.
Short-term (t < 3 min) with cold start (p < 30 bar, n ≤ 1000 rpm, tmin = -40°C).
Note that the maximum hydraulic fluid temperature must not be exceeded locally either (e.g. during storage). The temperature in the bearing area is - depending on pressure and speed - up to 12 k higher than the average case drain temperature.
Special measures are necessary at temperatures between -25°C and -40°C. Please contact us.
Shaft seal ring
The service life of the shaft seal ring is affected by the speed of the motor and the case drain pressure. The permitted loading with intermittent case drain pressure depends on the rotational speed (see chart). Short-term (t < 5 s) pressure spikes of up to 6 bar absolute are permitted.
The average permanent case drain pressure must not exceed 3 bar absolute. The pressure in the case must be equal to or greater than the external pressure on the shaft seal ring.
Flushing and Boost Pressure Valve
The flushing and boost pressure valve is used to remove heat from the closed circuit and to ensure that a minimum charge pressure is present (opening pressure 16 bar, fixed; note when setting primary valve). A side effect is flushing of the case.
Warm pressure fluid is removed from the relevant low pressure side into the motor case. This is then fed into the reservoir, together with the leakage fluid. The pressure fluid drawn out of the closed circuit in this way has to be replaced by cooled oil that is pumped in by the charge pump. In the open circuit, the flushing and boost pressure valve is used solely to flush the case from the return line.
The valve is fitted to the variable displacement motor (or integrated into the servo unit, depending on the type of control and the size).
