4.2. ORDINARY MAINTENANCE OPERATIONS
Here below are the tables showing the periodical maintenance required by the
machine to operate efficiently and safely.
Values shown refer to a normal use of the machine; heavy-duty conditions or
particularly abrasive/aggressive products may reduce sensibly the life of some
parts, which should therefore be checked more frequently.
In case of machine malfunction or abnormal noise, we suggest you try to
identify the components which seem to produce the noise and check whether
they have been correctly assembled and tightened or whether they might be
worn and in need of replacement.
In particular, machines operatine on very high pressure (over 600 bar)
require frequent servicing to replace gaskets, plunger seals, delivery
valves, valve seats and springs, homogenizing valves, depending on the
type of product used – see the Table of Periodical Maintenance for high
pressure machines – in addition to regular checks.
All the operations listed here below are described with detailed procedures in
the following paragraphs.
Execute carefully all the checks prescribed in these tables and note
scrupulously the DATE, MACHINE HOURS, OPERATOR in the Tables for the
checks to be performed every 1500 HOURS - 6 MONTHS and every 3000
HOURS - 12 NONTHS. In this way the machine will be maintained in the best
conditions of running and safety, and a track will be kept of the maintenance
operations actually completed.
CAUTION: The Periodical Maintenance tables shown below refer to normal
operating conditions and in any case provide merely an indication as to
the average life of a component and not a guarantee of minimum
component life.
Special conditions such as high operating pressure, high temperature,
steam sterilization and frequent washing, incorrect operating procedures,
can substantially affect the life of the machine and of its components and
therefore the intervals suggested for maintenance of compression head
components may vary significantly.
As additional tool for ordinary maintenance of the machine, please refer to the
form “CHECKLIST FOR MACHINE INSPECTION” at Section 5 – SPARE
PARTS LIST.
