Attention:
Carefully apply these prescriptions.
3.1.
General recommendations
• Installation and maintenance must be carried out with the unit
totally disengaged from its drive system and must be performed by
qualified personnel.
• Use adequate clothing (avoid ties, loose sleeves, necklaces and
so on) and suitable protection equipment (gloves, protection glasses,
boots...).
• To prevent errors and hazardous situations, establish what each
operator is responsible for in the different maintenance operations.
• When transporting the Julia group, use proper slinging. Store the
pump in stable places.
• Make sure that all the parts of the unit are idle and cool, before
performing any maintenance operation.
• Before each maintenance operation, stop the pump and restore
the atmospheric pressure.
• When the pump is running, some parts may reach very high
temperatures (above 100°C). Use all necessary precautions to avoid
contact.
• Operators working nearby must avoid prolonged exposure to the
noise emitted by the aspirator, if not equipped with the proper ear-
protection devices.
• Avoid accidental suction of solids: solids may be projected at high
speed through the exhaust manifold and cause injures.
• Do not introduce hands or objects inside the pump ports during
functioning.
• 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.
Do not exceed the power supply parameters
indicated in the technical tables (see par. 2.1, 2.2,
2.3 and 2.4).
3.2.
Intended use
• Julia 3000-5000-7000-8000-8500-9000 units, composed of
vacuum pump and centrifugal pump, are built for installation upon
trailers for agriculture application. Vacuum pump is used for suction or
discharge of the tank used for manure transportation. The centrifugal
pump instead is used for pressure spreading of manure.
• Julia 7000 HP unit, composed of vacuum pump and high pressure
pump, is suggested for installation upon trailer. The vacuum pump is
used for loading and discharge of the manure tank. The high pressure
piston pump is used for washing operations by means of clean water
(usually loaded inside a suitable tank compartment).
• Liquids or solids infiltrations can seriously damage the pump.
• Do not run the pump over its designed operating limits (see par.
2.1, 2.2, 2.3 and 2.4): it may break and transmission can be damaged.
3.3.
Conveyed fluids
• The Julia group vacuum pump is suitable for conveying filtered air:
if other types of gas are sucked, check compatibility with the machine
characteristics. Jurop has a technical service at disposal for any kind of
information.
• The introduction of foreign matter or liquids in the vacuum pump or
the introduction of large-sized foreign matter in the centrifugal pump
may damage the Julia group. Install a suction filter. In case of
occurrence, immediately stop the machine and clean.
