(1) clean equipment inside and outside neat, each sliding surface, no oil, no oil leakage in all parts, no air leakage, equipment around the chips, debris, dirt to be cleaned up;
(2) neat tools, accessories, workpiece (product) to be placed neatly, pipelines, lines should be organized;
(3) lubrication is good refueling or oil change on time, not oil, no dry friction phenomenon, oil pressure is normal, oil mark brightly, no dry friction phenomenon. The oil pressure is normal, the oil mark is bright, the oil circuit is smooth, the oil quality meets the requirements, the oil gun, the oil cup, the oil felt is clean;
(4) Safety Observe the safety operation regulations, do not overload the use of the equipment, the equipment's safety guards are complete and reliable, and eliminate the insecurity factors in time.
Maintenance content generally includes routine maintenance, regular maintenance, periodic inspection and accuracy checks, equipment lubrication and anti-freezing, anti-condensation system maintenance is also an important part of instrument maintenance.
The daily maintenance of the instrument is the basic work of equipment maintenance, must be institutionalized and standardized. Regular maintenance of the instrument is a planned preventive inspection, the means of inspection in addition to the human senses, but also a certain inspection tools and instruments, according to the regular inspection program, regular inspection of some people also known as the periodic inspection, the instrument should also be carried out to check the accuracy of the instrument in order to determine the degree of the actual accuracy of the degree of superiority or inferiority.
Instrumentation maintenance should be carried out in accordance with the maintenance program. Instrumentation maintenance program is the daily maintenance of the instrument requirements and regulations, adhere to the implementation of instrumentation maintenance.
(1) daily maintenance. Refers to the instrumentation of routine inspection, maintenance, cleaning, troubleshooting and other activities per shift, the main contents are:
View the instrumentation instructions, records are normal, the field once the instrumentation instructions, regulating valve valve position and the control room display value, whether the output value is the same;
Check the instrumentation power supply, the gas source is in the normal range;
Check the instrumentation heat preservation, accompanied by the thermal conditions
Instrument body and connectors damage and corrosion;
Check the instrumentation and process interface to check the leakage and degree of fastening;
Check the instrumentation equipment, cabinets, engineers station cleanliness and rodent-proofing;
Process computer control to check the system and instrumentation intact and operating conditions;
Production process of various instrumentation Failure of various instruments in the production process to find the cause and deal with the work.
(2) regular inspection and maintenance. Refers to regular scheduled inspection and maintenance of instrumentation equipment in accordance with the regulations, the main contents are:
regular lubrication, drainage, exhaust, drainage, check the isolation fluid and winter anti-freezing and anti-condensation checks;
regular inspection of various instrumentation system power supply, wiring, grounding, insulation, explosion-proof;
regular process computer control system for environmental health thoroughly cleaned, on the Cabinet, cabinet room air conditioning, printing equipment, floppy disk drives and other cleaning, cleaning filters, regular data backup, etc.;
Analysis hut environment temperature and humidity, rodent-proof, insect-proof, as well as the standard liquid, standard gas, sample gas, carrier gas replacement, etc.;
Maintenance Records:
Instrumentation equipment maintenance must be set up to establish a sound basis for the technical data, the maintenance work must be carried out according to requirements. Maintenance work must be required to make records. The main maintenance records are:
Special care unit records
Turnover records
Fixed toxic (combustible) gas detector sampling records
Tour inspection records
Automation equipment maintenance records (lubrication, instrumentation wind, heat preservation accompanied by heat)
Defective automation system equipment record
Automation equipment maintenance record
Automation system equipment failure record
Automation system equipment overhaul record
In the winter to carry out instrumentation inspection and maintenance of the focus - heat preservation accompanied by heat
