In the
chemical industry, petrochemical industry, and many other industries, chemical
pumps, centrifugal pumps, magnetic pumps and other equipment are repaired in
order to restore their functions after deterioration or failure, including all
kinds of planned maintenance and unscheduled fault maintenance and other
maintenance. The basic contents of pump equipment maintenance include: equipment
maintenance, equipment inspection, equipment repair and replacement.
Pump
maintenance type
Post accident maintenance
In the maintenance strategy
after the equipment works to the occurrence of obvious faults, the measures
taken are to dismantle the damaged equipment or components for repair or
renewal.
characteristic:
① The cost of maintenance is high and a waste of
time, delaying normal production.
② Reserve various spare parts for
replacement; Allocate more maintenance workers to deal with
maintenance.
Regular preventive maintenance
Go to the site for maintenance
according to the predetermined time interval, and repair or replace the
equipment before major faults occur.
characteristic:
① The maintenance
cost is less than that after the accident.
② Improper maintenance interval
will cause unnecessary excessive maintenance.
Condition monitoring and
maintenance
Based on the actual working condition of the equipment, it is
implemented through the monitoring results of the equipment.
Whether to
repair depends on abnormal phenomena such as mechanical vibration, bearing
temperature and running noise.
If a selected parameter reaches the
predetermined critical value, the equipment will be shut down for maintenance,
so as to avoid more serious accidents.
characteristic:
① The maintenance
goal is clear and the production efficiency is high.
② It is necessary to
purchase corresponding testing equipment and train personnel.
Standard
preventive maintenance procedures
Daily inspection work content
① Check
whether the discharge pressure of the pump is normal.
② Check the sound,
vibration and bearing temperature when the pump is running.
③ Check the pump
body and auxiliary pipelines for leakage.
④ Check whether the coupling guard
is loose.
⑤ Check the amount of lubricating oil and sealing cooling
water.
⑥ Keep the equipment clean.
⑦ If any abnormality is found, report
to the dispatcher.
