CZPT fluid
Just before beginning undertaking plHangCZPT, make sure you refer to our information sheets RE 95710 (mineral oil), RE 95711 (environmentally acceptable hydraulic fluids), RE 95712 (HFD hydraulic fluids) and RE 95713 (HFA, HFB, HFC hydraulic fluids) for thorough details regarding the choice of hydraulic fluid and software problems.
The variable motor A6VM is not ideal for operation with HFA hydraulic fluid. If HFB, HFC, or HFD or environmentally acceptable hydraulic fluids are utilized, the limits regarding technological knowledge or other seals must be observed.
Specifics relating to the selection of hydraulic fluid
The right option of hydraulic fluid needs information of the operating temperature in relation to the ambient temperature: in a closed circuit, the circuit temperature, in an open circuit, the reservoir temperature.
The hydraulic fluid should be decided on so that the operating viscosity in the functioning temperature range is inside the ideal variety.
We suggested that the larger viscosity course be selected in each situation.
Instance: At an ambient temperature of X °C, an operating temperature of sixty °C is established in the circuit. In the the best possible viscosity range, this corresponds to the viscosity lessons VG forty six or VG 68 to be selected: VG sixty eight.
Observe: The scenario drain temperature, which is impacted by strain and pace, can be larger than the circuit temperature or reservoir temperature. At no level of the ingredient may possibly the temperature be greater than 115 °C. The temperature big difference specified is to be taken into account when figuring out the viscosity in the bearing.
Temperature range
The FKM shaft seal might be used for case drain temperatures from -twenty five °C to +one hundred fifteen °C.
Observe: For application instances beneath -twenty five °C, an NBR shaft seal is necessary (permissible temperature variety: -40 °C to +ninety °C).
State NBR shaft seal in simple textual content when purchasing.
Shaft seal
The provider lifestyle of the shaft seal is motivated by the pace of the axial piston device and the scenario drain strain (situation pressure).
The suggest differential pressure of two bar in between the circumstance and the ambient stress could not be enduringly exceeded at normal functioning temperature. For a greater differential force at decreased speed, see diagram. Momentary strain spikes (t < 0.1 s) of up to 10 bar are permitted. The service life of the shaft seal decreases with an increase in the frequency of pressure spikes.
The circumstance pressure should be equal to or higher than the ambient pressure.
Hd – Proportional management hydraulic
The proportional hydraulic management offers infinite placing of the displacement, proportional to the pilot force utilized to
port X. – Beginning of handle at Vg max (optimum torque, least velocity at bare minimum pilot force) – Finish of control at Vg min (minimum torque, maximum permissible speed at greatest pilot force)
Observe
– Highest permissible pilot pressure: pSt = a hundred bar
– The manage oil is internally taken out of the higher-pressure facet of the motor (A or B). For reputable control, an operating force of at the very least 30 bar is needed in A (B). If a control operation is done at an functioning pressure < 30 bar, an auxiliary pressure of at least 30 bar must be applied at port G via an external check valve. For lower pressures, please contact us.
Make sure you notice that pressures up to 450 bar can take place at port G.
– Please state the wanted starting of manage in plain textual content when ordering, e. g.: beginning of handle at ten bar.
– The starting of control and the Hd characteristic are affected by the case strain. An increase in scenario strain leads to an boost in the starting of handle and therefore a parallel change of the attribute.
– A leakage stream of greatest .3 L/min can escape at port X thanks to inside leakage (functioning strain > pilot strain).
The management is to be suitably configured to keep away from an unbiased create-up of pilot pressure.
EP – Proportional handle electric powered
The proportional electric manage provides infinite location of the displacement, proportional to the handle present utilized to the
solenoid (sizes 28 to two hundred) or proportional valve (dimensions 250 to 1000). For dimensions 250 to a thousand, the pilot oil source at port P requires an
external stress of pmin = thirty bar (pmax = one hundred bar). – Beginning of management at Vg max (highest torque, minimum pace at minimum control existing) – Stop of control at Vg min (least torque, maximum permissible speed at maximum management existing)
Note
The control oil is internally taken out of the higher-stress facet of the motor (A or B). For reputable control, an working force of at minimum thirty bar is needed in A (B). If a manage procedure is done at an functioning force < 30 bar, an auxiliary pressure of at least 30 bar must be applied at port G via an external check valve. For lower pressures, Please note that pressures up to 450 bar can occur at port G.
The following only needs to be mentioned for sizes 250 to one thousand:
– The beginning of control and the EP characteristic are affected by the circumstance pressure. An enhance in situation force
triggers an boost in the beginning of control and therefore a parallel change of the characteristic.
HZ – Two-point handle hydraulic
The two-stage hydraulic control enables the displacement to be set to both Vg min or Vg max by switching the pilot strain at
port X on or off. – Position at Vg max (with out pilot force, maximum torque, least velocity)  – Place at Vg min (with pilot stress > ten bar activated, least torque, highest permissible velocity)
Be aware
– Greatest permissible pilot stress: 100 bar
– The management oil is internally taken out of the large-force side of the motor (A or B). For dependable manage, an operating pressure of at minimum 30 bar is required in A (B). If a control operation is executed at an operating strain < 30 bar, an auxiliary pressure of at least 30 bar must be applied at port G via an external check valve. For lower pressures, Please note that pressures up to 450 bar can occur at port G.
– A leakage circulation of optimum .3 L/min is current at port X (operating strain > pilot pressure). To avoid a create-up of pilot force, stress is to be relieved from port X to the reservoir.
EZ – Two-position management electrical
The two-level electric handle with switching solenoid (sizes 28 to two hundred) or management valve (dimensions 250 to one thousand) makes it possible for the displacement to be set to both Vg min or Vg max by switching the electrical recent at the switching solenoid or control valve
on or off. Be aware: The management oil is internally taken out of the high-force aspect of the motor (A or B). For reliable manage, an functioning stress of at the very least thirty bar is necessary in A (B). If a control procedure is performed at an running strain < 30 bar, an
auxiliary strain of at the very least thirty bar need to be applied at port G through an external verify valve. For decrease pressures, Make sure you observe that
Notice
– Maximum permissible pilot pressure: a hundred bar
– The management oil is internally taken out of the substantial-stress side of the motor (A or B). For reputable control, an running stress of at the very least 30 bar is necessary in A (B). If a control procedure is executed at an functioning stress < 30 bar, an auxiliary pressure of at least 30 bar must be applied at port G via an external check valve. For lower pressures
Remember to note that pressures up to 450 bar can occur at port G.
– A leakage flow of optimum .3 L/min is existing at port X (functioning stress > pilot stress). To stay away from a create-up of pilot pressure, strain is to be relieved from port X to the reservoir.
HA – Automated control higher-pressure related
The automatic high-force relevant handle adjusts the displacement immediately depending on the running stress.
The displacement of the A6VM motor with HA handle is Vg min (optimum speed and bare minimum torque). The manage device measures internally the functioning strain at A or B (no control line needed) and upon reaching the beginning of manage, the
controller swivels the motor from Vg min to Vg max with improve of strain. The displacement is modulated amongst Vg min and Vg max, thereby based on load circumstances. – Beginning of manage at Vg min (least torque, maximum
pace) – Stop of control at Vg max (optimum torque, minimum velocity)
Notice:
– For security causes, winch drives are not permissible with starting of management at Vg min (common for HA).
– The management oil is internally taken out of the large-force facet of the motor (A or B). For reputable manage, an operating strain of at the very least 30 bar is required in A (B). If a manage procedure is executed at an operating pressure < 30 bar, an auxiliary pressure of at least 30 bar must be applied at port G via an external check valve. For lower pressures, please contact us.
Make sure you observe that pressures up to 450 bar can happen at port G.
– The commencing of manage and the HA characteristic are influenced by the circumstance pressure. An improve in situation stress brings about an boost in the commencing of handle and as a result a parallel shift of the attribute. Only for HA1T (dimensions 28 to two hundred) and HA1, HA2, HA.T, (measurements 250 to a thousand).
– A leakage flow of maximum .three L/min is existing at port X (working force > pilot stress). To steer clear of a create-up of pilot stress, stress is to be relieved from port X to the reservoir. Only for management HA.T.
