Electromechanical equipment operation, maintenance, maintenance measures

First, the institutional settings

In order to maintain and manage the equipment, in the process of operation, maintenance and overhaul of electromechanical equipment, an electromechanical equipment management team consisting of the head of the power plant is set up. The full-time electromechanical equipment engineer is used to track the whole process of equipment maintenance and maintenance. recording. Set up an electrical and mechanical maintenance team to be responsible for the daily maintenance, maintenance and overhaul of the equipment.

Second, management methods

Formulate a sound electromechanical management system to achieve full equipment security management and control equipment operation status in real time.

3. Establish equipment lubrication management system:

According to the requirements of the equipment manual, the corresponding lubrication management system is formulated. The main contents include: equipment lubrication cycle, lubrication method, primary oil injection amount, lubricant oil change interval, cleaning method, etc.

V. Equipment operation, maintenance, maintenance management content

1. Equipment charter:

(1) Equipment charter and operator should master the lubrication knowledge of the equipment, such as lubrication parts, grease grade, oil injection quantity, oil injection cycle, etc., and regularly replace (supplement) the lubricating oil (fat) in accordance with the lubrication system. Make a record of lubricant (fat) replacement (supplement).

(2) The charter personnel must conduct a full patrol inspection of the charter machine every day.

(3) The charter personnel must understand the inventory of equipment spare parts (including consumable parts); the charter personnel must be aware of the hidden troubles and promptly propose corresponding maintenance plans.

2. Equipment inspection:

(1) Post inspection: The operator checks the appearance, lubrication, leakage, temperature, running sound, etc. of the equipment through visual inspection, touch, auscultation, etc., and checks every hour.

(2) Inspection of electromechanical maintenance workers: Electromechanical maintenance workers shall check the sliding parts, rotating parts and load supporting parts of the equipment by auscultating screwdrivers, thermometers, electrical instruments and other equipment, and inspect each class once.

(3) Inspection requirements:

Inspection cycle and time:

1) Under normal circumstances, personnel in each position conduct an hourly inspection of the equipment within the scope of the position.

2) When special conditions such as unstable production, abnormal climate or parking are started, the number of inspections should be increased to ensure safe production.

3) All post personnel must conduct inspections according to the specified time, and the error shall not exceed ±15 minutes.

Inspection content:

1) The fastening of each part of the equipment: Whether the anchor bolt and the connecting screw are loose, and the equipment is stable.

2) Equipment lubrication: Whether the equipment is short of oil.

3) Equipment sealing: Check whether the machine, pump, pipeline and valve are running and dripping, and the oil pressure gauge indicates whether there is any change.

4) Equipment temperature and odor: Check whether the temperature of the equipment is normal and whether the odor is abnormal.

5) Equipment sound: Whether the running sound of the motor, reducer, etc. is normal.

6) Equipment vibration: Check the equipment for abnormal vibration.

7) Corrosion of equipment: Check whether the equipment is corroded and the degree of corrosion.

8) Equipment instrument parameters: Check whether the equipment operating pressure gauge, temperature gauge, etc. are normal, and record the corresponding parameter values.

9) Equipment hygiene: Check whether the equipment is clean and tidy.

10) Equipment operation: Check whether the belt conveyor, scraper, etc. are operating normally.

Inspection method:

1) Check with the method of “listening, touching, watching, smelling, and checking”.

2) The inspectors are flexible according to their personal circumstances, and should be patient, meticulous, comprehensive and thoughtful, and do not miss any content.

Sixth, specific measures

1. Strengthen the inspection of equipment and the investigation of electromechanical hidden dangers. Strictly implement the 24-hour analysis system of inspection data and implement a secondary re-examination system for the over-limit data to ensure timely detection and timely processing of hidden dangers. Organized by the electromechanical deputy director, the machine repair workshop actively cooperates to comprehensively and meticulously investigate the hidden dangers of equipment in the monthly special inspection of electromechanical, especially to strengthen the inspection of faulty multiple elements such as belt conveyor, vibrating screen and transformer room. The source curbs the hidden danger of germination.

2. Strengthen equipment maintenance and repair. Strengthen the complementary coordination of daily maintenance and planned preventive maintenance of equipment, and do a good job in closed-loop management of inspection, preventive maintenance and operation tracking. Focus on key and vulnerable equipment in the maintenance plan; give priority to the regular maintenance and lubrication of the equipment; make full use of the role of specialized maintenance personnel in the machine repair workshop to improve the quality of maintenance.

3. Improve the emergency response speed of electromechanical accidents. The centralized control room and the machine repair workshop should play their respective functions and fully cooperate with the “Electromechanical Accident Repair Team” to carry out the work. At the same time, it adopts the form of “burst accident repair drills” from time to time to enhance employees' quick reaction awareness and find accident repairs. In order to compress the repair time for a reasonable process, it is necessary to arrange the employee's vacation reasonably and strictly control the personnel to go out; the team leader and above personnel and the two-shift maintenance personnel of the machine and electricity require a 24-hour mobile phone to start the problem in time for problems.

4. Strengthen the management of inventory materials. In order to ensure the reliable operation of the equipment, the implementation of the “Material Tracking Feedback” safeguard measures will be implemented, and real-time tracking feedback will be made on the inventory, reporting, procurement and arrival of materials to ensure that the material reserves are adequately in place and at the same time ensured The main equipment and materials reserves are scientific and reasonable, avoiding unnecessary duplication of reserves.

5. Strengthen the management of industrial equipment. The machine repair shop inspects the integrity of the special maintenance tools and machine tools, and the electrical tools of the electrician class. The incomplete tools need to be replaced in time. The special maintenance equipment should self-check and test its performance regularly to ensure the reliability of special tools. And special maintenance equipment needs to be spared to ensure multiple inspections at the same time.

6. Strengthen equipment protection inspection. Intensify the inspection of the protection of various types of equipment such as belt conveyors and scraper machines, and require full inspection and testing of the protection of major production equipment in each class to ensure reliable protection and smooth production.

7. Carry out various kinds of problem feedback and exchange activities, for example: regularly hold electromechanical work symposiums, and deal with the occurrence of electromechanical problems in a timely manner; “on-site under duty leadership” should solve the problems found on the spot; The experience and technology, for the case of discovery, should be arranged in time for the whole plant to do the rectification work.

8. Strengthen the management of key equipment. For some equipment with frequent failures or key parts, special “operational safety technical measures” should be formulated, in which rigorous and effective safeguard measures are formulated from the aspects of production, electromechanical maintenance and daily management.

Heavy Duty Casters

Heavy casters are used for the movement of heavy equipment, so the wheels of heavy casters generally use a single wheel with a hard tread. Nylon wheels, cast iron wheels, forged steel wheels, hard rubber wheels, polyurethane wheels, and phenolic resin wheels are ideal. Among them, forged steel wheel and polyurethane caster wheel are especially suitable for the wheels of extra heavy casters.
