www.fraserwoods.ca • Do not start the machine if the protection devices provided for transmissions are removed. Replace damaged parts. • Pressure relief valve: point the air flux away from the operators. • Do not use the aspirator over its designed limits: the machine may be damage and the operator may be injured.
www.fraserwoods.ca CHECKING UPON RECEIPT • When the goods are delivered, make sure that all parts listed on the delivery note are in perfect condition and have suffered no damage during shipping. • Make sure the vacuum pump has its identification plate affixed on the front cover. Pumps without such identification are to be considered anonymous and potentially dangerous: in such an event, they must not be used, otherwise the manufacturer will be deemed free from any liability whatsoever.
www.fraserwoods.ca • Max. pressure safety valve on delivery: mount it close to the pump. The valve flow must prevent the PN155 from exceeding the absolute operating pressure (see par. “Usage limitations”) or, in any case, the maximum pressure allowed by the system. Do not apply gate valves on the line. •...
www.fraserwoods.ca BELT DRIVE CHECK BELT TENSION 3300 N KEEP AXELS PARALLEL ALIGN PULLEY GROVES AND BELTS 35 MAX • Install a suitable pulley on the smooth shaft as close as possible to the pump: max 35 mm. • Apply an adequate belt tension (see manufacturer’s data). Max 3000N. •...
www.fraserwoods.ca • Filtration: class 19/16 contamination according to ISO 4406 DRAINING to be obtained with a ßx = 75 filter PORT • Check circuit connections: they must be applied in the same rotation direction as that indicated by the arrow on the pump front flange.
www.fraserwoods.ca Check which position of the four-way integrated valve lever allows vacuum or pressure functioning. Close the valve and increase vacuum rate (or operating pressure). Check that the lubricating pump works properly. Oil must regularly drip into the oilers. Typically 35 drops/min (at maximum speed).
www.fraserwoods.ca 11. ORDINARY MAINTENANCE Before starting any maintenance operation, follow the safety prescriptions as described in paragraph “Safety and accidents prevention”. PUMP OPERATION CHECKING FREQUENCY CONDITION Lubrication: dripping into oilers OPERATING Rotating speed Working pressure Side mounted tank oil level Clean filter and vacuum line shutoff.
www.fraserwoods.ca CHECKING THE VANES WEAR • Unscrew the vanes wear check-plug on the housing. • Turn the shaft until you see the vane. • The vanes should slide to the bottom of the seat due to gravity: check they really do. Replace the vanes when their wear exceeds 10 mm (L –...
www.fraserwoods.ca REPLACING THE VANES • Remove the vacuum pump from its bearing frame and wash it before disassembling. • Disconnect the lubricating piping. Remove the screws fixing the rear flange and use the two threaded holes to remove the flange – bearing – seal housing. If necessary, hold the rotor by inserting a wooden block, protecting the internal bearings from damage.
www.fraserwoods.ca 13. TROUBLESHOOTING The vacuum pump overheats Insufficient or absent lubrication Verify oil and rings. Check oil pump efficiency Low tank oil level Fill tank with oil Excessive rotation speed Reduce rpm to the prescribed working speed Prolonged functioning at max vacuum rate Reduce vacuum rate Vacuum and/or exhaust line of insufficient diameter Check dimensioning...
