8, maintenance and troubleshooting
1, maintenance
Chamber filter press in the use of the process, the need for sports sites (such
as chain, bearings, rod, etc.) for lubrication, and some automatic control
system of the feedback signal devices (such as pressure relays, electric contact
pressure gauge and limit switch action the accuracy and reliability must be
guaranteed.
So as to ensure the normal operation of filter press. Therefore, we should
do the following:
(1) use good operating records, the functioning of the equipment and the problems
of recording the record, and shall promptly carry out maintenance of equipment
failure.
(2) maintaining the site with the cleaning, and added an appropriate amount
of lubricant to ensure its lubrication properties. Piston rod should be regularly
cleaned.
(3) on the electrical control system, to conduct tests and movements insulation
reliability test, the action is not flexible or dynamic accuracy of the components
of a difference is found, promptly repaired or replaced.
(4) regular checks of plate sealing surface to ensure its smooth, clean, check
whether the folded cloth to ensure its smooth and intact.
(5) The hydraulic system maintenance, mainly for liquid fuel tank, hydraulic
components, sealing the various ports of inspection and maintenance, and to
ensure the cleanliness of hydraulic oil.
(6) If the device does not use a long time, should plate clean, dry cloth after
cleaning. Manifold and the exposed parts of the piston rod to be coated with
butter.
