1,Project planning, assembly and commissioning of the axial plunger unit must be carried out by qualified personnel.                                        Before using the axial plunger unit, please read the corresponding instruction manual. If necessary, please ask Bosch Rexroth for these handbooks. 2, Axial plunger units (especially electromagnets) may be at risk of burning during and shortly after operation. Appropriate safety measures (such as wearing protective clothing) should be taken.
3, Depending on the working conditions (working pressure, oil temperature) of the axial plunger unit, the characteristics may change.
Work Pipeline Oil Port:
1, Oil nozzles and fixed threads are designed for maximum specified pressure. Machine or system manufacturers must ensure that the safety factor of connecting components and pipes meets the specified working conditions (pressure, flow, hydraulic oil, temperature). 2, Work pipeline nozzles and functional nozzles are only designed for hydraulic pipelines.
Pressure cut-off and pressure control do not provide overvoltage protection. Separate relief valves are provided in the hydraulic system.
3,He data and instructions contained here must be followed.

4, the product cannot be approved as a component that follows the general mechanical safety concept of ISO 13849. 5, Use the following tightening torque:
Connector: Install bolts:
Refer to manufacturer's instructions for tightening torque of the joints used. 1, for installation bolts that meet the ISO metric thread standard of DIN 13 and the thread standard of ASME B1.1, we recommend that tightening torque be checked separately according to VDI 2230.
 
2, Thread holes in the axial plunger unit:
3, the maximum allowable tightening torque MG Max is the maximum value for threaded holes and shall not exceed that value. for numerical values, see the table below.
Locking screw:
1, for the metal locking screw provided with the axial plunger unit, the tightening torque MV is required.
Installation instructions:
1, during commissioning and operation, the axial plunger unit must always be filled with hydraulic oil and exhaust air. When the shutdown time is relatively long, the precautions mentioned above should also be observed, because the axial plunger unit is emptied through the hydraulic pipeline. 2, Especially in the "drive up/down" installation position, oil injection and exhaust must be thoroughly carried out, otherwise there will be no oil operation and other dangers. 3, the oil leakage from the shell of the motor shell must be discharged to the tank through the highest shell outlets (L1, L2, L3). 5, in order to obtain a favorable noise value, elastic elements should be used to separate all connection lines and avoid installation above the tank.
4, for the combination of multiple equipment, it should be ensured that the corresponding shell pressure of each equipment is not exceeded. When the pressure difference exists at the outlet of the equipment, the common pipeline must be replaced so that in any case, the minimum allowable shell pressure of all the connecting equipment is not exceeded. If this is not possible, separate oil discharge pipelines should be laid if necessary. 6, under all operating conditions, the suction pipeline and shell drain pipeline must be accessed to the position below the lowest oil level in the tank. the allowable oil absorption height hS depends on the total pressure loss, but it will not be higher than its maximum value (hS max = 800 mm). during operation, the minimum oil suction pressure of the nozzle S should not be lower than 0.8 bar absolute pressure.
Installation location: Be careful:
1, See examples 1 to 12 below. 1, You may find that certain installation locations have an impact on the control equipment. Because of the existence of gravity, component weight and shell pressure, the characteristic displacement and response time may change slightly. Installation below the tank (standard) means that the axial plunger unit is installed outside the tank, below the lowest oil level.
2, Other installation locations can be provided as required.
3, Suggested installation locations: 1 and 3.
Installation above tank:
1, Installation above the tank means that the axial plunger unit is installed above the lowest oil level of the tank. 2, in order to prevent the axial plunger unit from emptying, the installation position 6 requires at least 25 mm height difference hES min to comply with the maximum allowable oil absorption height hS max = 800 mm. the one-way valve in the shell oil discharge pipeline is only allowed to be used in individual cases. for information on certification, please consult us.
Installation in tank:
1, Installation in the tank means installation of pumps within the minimum tank level. 2, Axial plunger units with electrical components such as electronic controllers and sensors cannot be installed below the oil level of the tank.
