  • Page 13: Suitability/General Information

    Suitability/General information The German version of these instructions is the “Original instructions”. Any version in a language other than German is a “Translation of the original instruc- tions”. Aerzener rotary piston machines are suitable for the oil-free conveying and compression of air and, if specially modified versions are used, various other types of gas.

  • Page 14: Construction, Function

    Construction, function Blower stage: The blower stage is supplied as a fully assembled unit. The following additional work must be carried out: • Correct installation/assembly in the relevant unit/system • Connect the conveying piping. • Check lubricating oil level. • Adjust level, if necessary.
  • Page 15 With a suction pressure version, we recommend that you install a suction valve in the piping on the intake side. No shut-off valves must be installed between the suction valve and blower stage. Suitable valves are available from Aerzener Maschinenfabrik. The valves are not intended to control the operating data! Filter silencer/Starting strainer A filter (or in the case of intake from a pipeline, a starting strainer) should be used to...

  • Page 17 • It must be ensured that a stopped positive displacement machine cannot be mo- ved from the rest position without operating the start function, no matter what the cause! • Damaged rotary piston machines or machines that are not in perfect working order must be replaced immediately.
  • Page 18 • Any evidence of dirt, dust or foreign matter must be removed from the intake area. • Compliance with the maintenance schedule is absolutely mandatory. Qualification of operators • Each person dealing with the installation, operation, maintenance and repair of this unit must have read and understood the operating instructions.
  • Page 19 the rotary piston machine. • Lubricating and control oil pipes should only be retightened or opened while the machine is in a depressurised state. • Depressurise conveying ducts before attempting to remove them. • When conveying technical gases, conveying ducts must be rinsed with a neutral gas before disassembly.
  • Page 20 • Risk of fire ! Risk of glowing embers ! • Depending on the size and increased fire protection regulations, a flame retardant foam would be applied according to the order. Information about the event of damage • If the unit produces an abnormal and/or unusual sound, the machine must be shut down immediately using the EMERGENCY BREAK function.

  • Page 23 Installation/Assembly During installation the following points must be observed: • The blower must be installed on an a foundation, base and connections that are even, non-vibrating and slope-free. • CAUTION! If the blower is installed with a tilt, this will result in irreparable damage to the machine due to the uneven oil level.
  • Page 24 • There must be no distortion of the blower as a result of alignment or tightening operations. • Assemble the blower fixing screws in the correct manner. - Please observe the foot assembly drawing 139 006. - According to drawing 139 006, the length of the bush should be determined within the context of assembly.
  • Page 25 Piping • When installing the piping on the intake side, ensure that it is clean. Foreign bodies and dirt will damage the blower. • Any piping that is to be connected must be carefully cleaned and must be free from foreign bodies. •...

  • Page 26: Commissioning

    Commissioning Install and assemble the blower stage in accordance with these instructions. Assemble the driving elements correctly. CAUTION! Do not establish any connection with the driving motor yet. On first commissioning top up lubricating oil on empty machines. Check lubricating oil level and correct if necessary. Check that the oil filling plug and the drain valve are seated securely and do not leak.
  • Page 27 With the correct direction of rotation: The alignment of the belt pulleys/drive coupling should be checked. The V-belts should be attached/the drive coupling should be connected using connecting elements. Tension the V-belts. Observe the specifications regarding the belt tensioning force. Ensure that protective equipment is in place for the belt drive/drive coupling.
  • Page 28 Switch off / shutdown • Switch off is effected via the power switch on the motor. • To shut the unit down completely the fuses must be removed after the blower has come to a standstill. The valves on the conveying pipes must be closed. Avoid possible entry of condensate into the blower stage.

  • Page 29: Frequency Converter Operation

    Frequency converter operation • If the electric motor is driven by frequency converters, we strongly recommend using an engine throttle and power choke. These are specifically designed for the frequency converter and filter dangerous harmonics from the drive current. Damage to the motor winding can be prevented by improving the electromagnetic compatability of the system and reducing reactions of the frequency converter in the current.

  • Page 31: Maintenance Schedule

    Maintenance schedule Whenever work is carried out on the positive displacement machine, it must be switched off and isolated from the mains electricity supply. Failure to follow this instruction could result in injury or damage! Various steps should be taken to achieve a long service life and provide the optimum operating conditions. These include carrying out the maintenance work specified in this table at the intervals specified here.
