Precautions for mechanical maintenance, what need to be paid attention to in the maintenance of cons

It's also for the internship report. I just found it.

1. Proficient in the operating procedures, technical measures and management systems of equipment and facilities. And in strict accordance with the requirements of the regulations, measures and systems to do a good job in equipment operation, shall not be illegal operation or sloppy work, perfunctory.

2. It is necessary to establish the idea of urgency, deal with various problems efficiently with quality and quantity, complete their own work, and bring all the common tools to the work, and not delay the work for any reason.

3. Strengthen equipment maintenance, refueling and lubrication according to regulations, and maintain diligent maintenance within the specified maintenance period, regardless of the condition of the equipment when it expires, it should be repaired to avoid overload and overtime operation of the equipment, and avoid the passive maintenance of the equipment before it is repaired.

4. Under the following circumstances, equipment maintenance is prohibited:

When the equipment is running.

When the residual air of the pneumatic machinery is not cleaned, and the high-pressure oil of the hydraulic system is not cleaned.

When the main switch of the shunt power supply is not pulled down, the power supply of the equipment is not cut off, the warning sign of "overhaul the equipment, prohibiting closing" is not hung or there is no special person on alert.

When the operator has not been contacted.

5. Ensure the quality of connecting screws, clips, fasteners and hose joints when taking over the line. Strictly prevent falling off and falling into the well and injuring people due to poor quality during use.

6. To ensure the safety of the mechanics, the safety rope must be worn for high-altitude work, and the operation shall be strictly in accordance with the "Safety Measures for Aerial Work", and the personnel shall strictly implement the "Personnel System" when going up and down the well.

7. Small class machine repair and large class machine repair should be closely coordinated. It is necessary to have a clear division of labor and cooperate happily, and work together to deal with general problems and difficult problems, and must not shirk each other's responsibilities and affect work.

The power is cut off in advance, and the dismantled parts are placed in order. The strip parts should be hung vertically, and the parts should be cleaned .........

In order to ensure the safe operation of construction machinery and prolong the service life of locomotives, daily inspections are required: If any fault is found during the inspection, the cause should be found out and the locomotive should be adjusted or repaired to prevent the breakdown from spreading. Locomotives operated when they are not troubleshooting, which can lead to serious accidents.

The rock boring machine should be inspected daily, and the visual inspection should be carried out before the starter of Brother Biqing. Ways to check the surroundings of the locomotive and the bottom:

1. Whether there is leakage of organic oil, fuel and coolant.

2. Whether there are loose bolts and nuts.

3. Whether there are wire breaks, short circuits and loose battery joints in the electrical circuit.

4. Whether there is oil stain.

5. Whether there is an accumulation of people's property. After starting the engine, check that the mine TBM, the horn and all the instruments are in good condition.

1.Mouth before you move.

For faulty electrical equipment, do not rush to do it, and should first inquire about the process and failure phenomenon of the failure. For unfamiliar equipment, you should also be familiar with the circuit principle and structural characteristics, and abide by the corresponding rules. Before disassembly, you should be fully familiar with the function, location, connection mode and relationship with other devices around each electrical part.

2.Exterior first, then interior.

The equipment should be checked for obvious cracks and defects, and its maintenance history and service life should be understood, and then the inside of the machine should be inspected. Before dismantling, the surrounding fault factors should be eliminated and disassembled only after determining the fault in the machine, otherwise, blind disassembly may cause the equipment to be repaired more and more badly.

3.Mechanical before electrical.

Only after it is confirmed that the mechanical parts are fault-free, the electrical aspects are checked. When checking the circuit fault, the detection instrument should be used to find the fault part, confirm that there is no bad contact fault, and then check the operation relationship between the line and the machinery in a targeted manner to avoid misjudgment.

It reads as follows:

1. Make full use of the old equipment, and reuse the old is to "make full use of the old resources" to achieve the purpose of saving.

2. In the project, if there are duplicate parts used in multiple projects, then these duplicate machines that can be eliminated or shared are called old equipment.

Recycling is the process of turning waste into reusable materials, as opposed to reuse, which simply refers to the reuse of a product.

According to the Environmental Protection Agency, 13% of solid waste in the United States (i.e., waste disposed of through waste collection systems) is recycled. In contrast, 14% of solid waste is incinerated and 73% is disposed of in landfills.

Safety precautions for equipment maintenance:

1. Before equipment maintenance.

1. Preparation of labor protection supplies. Before entering the workshop, you must wear work clothes, labor protection gloves, protective glasses and other sensitive labor protection equipment.

2. Analyze the maintenance work to be carried out, the possible risks and hidden dangers, and take corresponding measures.

3. If you need to climb the height, you must wear climbing safety equipment, and warning signs must be placed below the climbing operation to remind passers-by to pay attention to falling objects.

4. Before equipment maintenance, check whether the electrical, hydraulic and pneumatic power sources are disconnected, and hang warning signs such as "repairing" and "prohibiting closing" at the switch or special person to supervise them, and the guardian shall not engage in operation or do anything unrelated to guardianship.

5. Before equipment maintenance, it is necessary to inspect, analyze and understand the causes and current status of the equipment rental posture and branch barriers. It is necessary to check whether there is floating medicine in all parts of the equipment, and if so, it must be repaired only after taking measures.

6. Before repairing, maintaining and maintaining the equipment, it is necessary to cut off the power supply and gas source of the main power supply of the equipment and the control elements such as photoelectric switches, travel switches, proximity switches, pneumatic components, etc., and the auxiliary components can only be repaired, maintained and maintained after confirming that the equipment will not malfunction.

1. Any mechanical equipment must be cut off from the power supply and hung up before disassembly"Repairs are underway"to avoid industrial accidents.

2. If you work under mechanical equipment, you should hang a sign of "under repair, do not turn the machine" on the repaired equipment.

3. When working at height, you should fasten your seat belt and take protective measures. Pay attention to safety when repairing, and do not drop tools and parts up and down to avoid accidents or damage to tools.

4. When large parts are hoisted, the rope should be firm, must be firmly tied, can not be tilted when lifting, and should be stable when placed.

5. If more than one person is required to operate in the repair, there must be a special person to command and cooperate closely with each other.

6. During the repair, it is not allowed to touch the sliding surface, rotating parts or threaded holes by hand.

7. Before the test run, check whether the power supply is connected to the correct attitude, and carefully check all parts of the machine to confirm that it is correct before driving.

Hello dear, rotating machinery overhaul should pay attention to: 1Resolutely implement the "safety first".

1. Prevention first". Safety in production is everyone's responsibility. Strictly supervise the implementation of these measures.

2.Anyone entering the production site except for the office, control room, duty room and maintenance room must wear a safety slag hat correctly. It is forbidden for staff to wear slippers and sandals when entering the production site.

When doing work that comes into contact with high-temperature objects, you should wear gloves and special protective work clothes. 3.It is forbidden to walk and sit on railings, pipelines, backrests such as sprockets, safety covers or bearings of equipment in operation, and safety measures must be taken when it is necessary to sit and stand on the pipes in order to work.

As much as possible, avoid staying close to and staying in areas where you may be burned.
