Maintenance System of Instruments and Equipment
I. Operators and maintenance (inspection) personnel should take an attitude of mastery to achieve the correct use, careful maintenance, and maintain the equipment with a serious attitude and scientific methods. Strictly implement the job responsibility system, the implementation of equipment package mechanism (each duty safety officer to manage the instruments and equipment in the area responsible for), to ensure that the equipment in use in good condition.
Two, the operator should correctly use the equipment, strictly comply with the operating procedures, start before the start of careful preparation, start in the repeated inspection, shutdown properly handled, running in the adjustment, the careful implementation of operating procedures and indicators, not allowed to over-temperature, over-pressure, over-speed, overloading operation. Through the operation practice and technical learning, to understand the structure, performance, use; will use, maintenance, troubleshooting.
Three, the operator in the use of instruments and equipment, should master the equipment failure prevention, judgment and emergency measures, to maintain the safety guards intact; after use, should cut off the power supply to work, keep the parts, accessories and tools intact; and carefully fill out the equipment operation records, defects records, and operation diary.
Four, the operator must conscientiously implement the shift system. If there is something left during the operation of the equipment, it is necessary to entrust other laboratory staff to take the place of the care, to ensure that in the operation of the equipment failure or accident, can take timely remedial action to avoid accidents and unnecessary losses.
Fifth, the equipment maintenance personnel responsible for the repair of the equipment, should be on time to carry out inspections, found that the problem is dealt with in a timely manner, with the operator to improve production safety.
Sixth, the safety officer on duty should be carefully maintained, strict implementation of the inspection system, the equipment on a regular basis to carefully check, find problems, solve them in a timely manner, to eliminate hidden dangers; such as problems can not be solved, should be timely to the department in charge of reporting the situation, and equipment purchasing manufacturers with the technical department of the equipment contact and communication to deal with the relevant issues.
Seven, the equipment plan to run, regular switching, the safety officer on duty with the overhaul personnel need to do a good job in the area responsible for the maintenance of instruments and equipment, so that it is often kept in good condition, to ensure that at any time you can start the operation of the spare instruments and equipment should be timed to do a good job of antifreeze, anticoagulation and other work.
Eight, the safety officer on duty should often keep the area responsible for equipment and environmental cleanliness and hygiene, so that the ditch to see the bottom, the shaft to see the light, the equipment to see the color, door and window glass net.
nine, all instruments and equipment, piping and other maintenance work, there must be a clear division of labor (the safety officer on duty to do their respective areas responsible for the maintenance work), and in a timely manner to do a good job of antifreeze, anticondensation, heat preservation, keep cold, corrosion, leakage prevention and other work, for example, to prevent the corrosion of the chemical substances within the precision balance, freeze-dryer vacuum pump to prevent the oil blockage, the surface of the instrumentation and equipment to prevent the paint from falling off the rust and so on. The situation.
Ten, the implementation and supervision of instrument and equipment maintenance operations:
(1) instrument and equipment maintenance must be carried out "maintenance and repair, prevention-oriented" principle, to achieve regular maintenance, mandatory, correctly deal with the use of maintenance and repair of the relationship. Improve the instrument and equipment cleaning, lubrication, adjustment, fastening, anticorrosion, the implementation of routine maintenance and regular maintenance system, in strict accordance with the instructions specified in the cycle and check the maintenance program.
(2) maintenance equipment to ensure the quality, according to the specified items and requirements one by one, shall not be missed or not insured. Maintenance projects, maintenance quality and maintenance of the problems found in the record should be made; maintenance personnel and maintenance departments should be self-inspection, mutual inspection, full-time inspection and a qualified handover, and constantly summarize the maintenance experience, improve the quality of maintenance; Asset Management Department of the Department of regular supervision and inspection of various departments of the instrumentation, regular or occasional spot checks on the quality of maintenance, and to reward and punish the poor.
(3) routine maintenance is before and after the operation of machinery and the process of cleaning and inspection, mainly to check the vital, vulnerable parts (such as mechanical safety devices), coolant, lubricants, fuel level, instrumentation instructions. Routine maintenance is completed by the operator himself, and carefully fill in the "Instrument and Equipment Maintenance Record".
(4) the first level of maintenance: universal cleaning, fastening and lubrication operations, and partially adjusted operations, maintenance of instruments and equipment in good condition. By the use of departmental organization and arrangement, asset manager check, department head supervision.
(5) the second level of maintenance: including the first level of maintenance of all the contents of the inspection, adjustment as the center, to maintain the instrumentation assembly, mechanism, parts with good working performance. By the use of departmental organization and arrangement, asset manager check, department head supervision.
(6) Seasonal maintenance: the main content is to replace the applicable seasonal lubricants, fuel, take anti-freezing measures, increase anti-freezing facilities. Organized and arranged by the department of use, the asset manager to check and supervise.
(7) go together period of maintenance: new instruments and equipment after the end of the go together period must go together period of maintenance, the main content is cleaning, fastening, adjustment and replacement of lubricating oil, by the use of the department to complete the asset manager to check, the head of the department to supervise.
(8) transfer maintenance: instrumentation and equipment transfer environment before the transfer of maintenance should be carried out, the content of the operation can be based on its technical condition of the maintenance, if necessary, can be anticorrosion. Transfer maintenance by the instrument and equipment duty safety officer arrangements for the implementation of the asset manager check, the department head supervision.
(9) Parking maintenance: deactivation and storage of instruments and equipment should be maintained, mainly cleaning, anticorrosion, moisture and so on. Inventory of equipment by the Asset Management Department commissioned by the maintenance of the rest of the equipment by the use of departmental maintenance.
(10) maintenance program should be completed after careful inspection and acceptance, and prepare the relevant information, so that the records are complete and true.
Commonly used instruments and equipment maintenance of special attention to the maintenance of matters
A large-scale instruments and equipment: universal testing machine, hot press
(1) need to be trained after learning to operate and use, and by the person to carry out maintenance and repair. A series of fixtures and other components need to be placed reasonably, keep intact, not rust, not damaged.
(2) before operation must wear good labor protection articles; will be removed from the machine above the irrelevant items.
(3) should establish a technical file, all kinds of information should be complete. Archived data include: order request form, contract, packing list, manuals, technical information and other original data and acceptance, installation and commissioning, use, operating procedures, maintenance, inspection, calibration, change, loss of the ring and other records. The use of records should include the date of use, the use of the name of the unit, the name of the user, the name of the test sample, open and close the time, test conditions, the use of the contents of the project.
Two, weighing instruments: electronic balance
(1) The balance should be placed away from the source of vibration, corrosive gases, temperature and humidity in the right environment. The working platform should be stable and reliable, avoid direct sunlight and air disturbance or one-sided cold and heat. Color-changing silica gel should be placed inside the balance cover, and acidic desiccant should be avoided.
(2) The weighed object should be placed in the center of the balance pan and should not exceed the maximum weighing capacity of the balance. When picking up and placing the object should pay attention to the light holding and placing.
(3) If the user finds that the balance is out of calibration or abnormal, it should be stopped, calibrated in time or after inspection and repair before use.
Three, precision instruments: Olympus microscope
(1) the lens is placed separately and separately in a desiccant vessel, it is best to use cotton swabs, gauze, soft brushes and other soft things to wipe, pay attention to can not be wiped with force to prevent damage to the coating layer. Oil mirror should be cleaned at that time, especially the 100X oil mirror, if not handled properly, the front piece is easy to soak the oil or open glue. Eyepieces can be removed and cleaned, 16X eyepieces, pay attention not to install the reverse, the concave side of the front piece on the top. Objective lenses should not be removed randomly. Pointer do not use hair to do, easy to dirty lens, manufacturers can be equipped with a pointer. General 2 months is best to focus on maintenance once.
(2) lens cleaning: clean dust with cotton swabs, gauze, soft brush and other relatively soft things to, pay attention to gentle and slow. Some of the more stubborn stains such as oil stains, fingerprints, etc., you can use a clean soft cotton cloth, cotton swabs lens paper dipped in anhydrous alcohol gently wipe away. If it is from the oil mirror to wipe off the immersion oil, should be lens paper, soft cotton cloth or gauze, dipped in xylene gently wipe away. Note that do not use xylene to clean the incident lens at the bottom of the binocular barrel or the prism surface inside the eyepiece. Because pure alcohol and xylene are flammable, be especially careful not to ignite these liquids when turning the power switch on or off. Prevention is better than cure.
(3) paint and plastic surface cleaning: against the use of organic solvents (such as alcohol, ether, thinner, etc.) to clean the instrument's paint and plastic surfaces, it is recommended that the use of silicone cloth, there are more stubborn stains can be used to use a soft cleaner to clean. Plastic surfaces can be cleaned with a soft cloth dipped in water.
(4) microscope idle processing: when the microscope in the case of vacation and other long time not in use, should be covered with a plastic cover, and stored in a dry place to prevent dust and mold. At the same time, it is recommended that the objective lens and eyepieces are stored in a container such as a desiccator, and put some desiccant.
Four, high-temperature and high-pressure instruments: vacuum drying oven
(1) electrical insulation is intact, the equipment shell must have reliable protection of grounding or protection of zero to ensure the use of safety.
(2) between the vacuum box and the vacuum pump is best across the filter to prevent the wet body into the vacuum pump.?
(3) The vacuum pump should change the vacuum pump oil frequently.
(4) When the electric vacuum drying box is not used for a long time, the contents of the box should be removed and wiped clean to keep the equipment dry.
(5) vacuum box should be kept clean frequently, box door glass should be wiped with loose cotton cloth, do not wipe with reactive chemical solvents to avoid chemical reaction and bruise the glass.
(6) If the vacuum box is not used for a long time, it should be coated with neutral grease or petroleum jelly on the plating parts to prevent corrosion, and set on the plastic film dust cover, prevented in a dry room, so as not to affect the use of the electrical parts by moisture.
