Electrical equipment

1. Characteristics of electrical equipment accidents

• 1. The risk factors of electrical accidents cannot be detected and prevented by sensory organs. Electricity is an objectively existent and real thing that has no shape, no color, no smell, and no sound, so to speak. In the process of use, it is easy to ignore its existence and lack of understanding of its danger, so it is easy to have an accident.

• 2. The risk of electrical accidents is great, with serious losses and high mortality rates. Once an electrical accident occurs, it will damage the equipment and cause power outages to affect production. If a person is electrocuted, it can cause electric shock, and severe it can cause disability, or even death; Electrical accidents can also cause electrical fires and explosions.

• 3. Prevent the occurrence of electrical accidents: We must have some basic knowledge of electricity, if you don't know anything about electricity, then electricity will threaten you all the time.

• 4. When an electrical accident occurs: it comes suddenly and without premonition, and once a person is electrocuted, he loses his ability to defend.

2. Prevent the occurrence of electrical equipment accidents

• 1. Always remind yourself that the danger of electric shock should be safe when using electricity;

• 2. Remind yourself at work not to pull or pull wires, do not move live mobile devices, do not touch live equipment without protection at will, and do not use equipment and power tools with potential safety hazards at will: such as equipment protective covers and protective covers have been removed, power cords are exposed, equipment has abnormal sounds, serious corrosion, rust and tilt.

• 3. Always ensure that you operate electrical equipment in strict compliance with proper procedures, avoiding any reckless or blind actions.

• 4. When operating electrical equipment, you must be familiar with the safety operation specifications of the equipment, and be proficient in the performance and working process of the equipment, and the process flow of the products produced.

• 5. If you are not familiar with the equipment or do not know how to operate, it is strictly forbidden to operate or refuse to operate.

• 6. Do not change the speed, time and process flow of the machine at will because you want to improve work efficiency.

3. Safe operation of electrical equipment

1. Operators of equipment shall not operate the equipment at will without pre-job training or proficiency in the equipment.

2. Operators should pay attention to operation safety during operation of the place where safety warning signs are posted on the machine.

3. For equipment equipped with safety protection devices, it is strictly forbidden to remove the protection device for work convenience or operate it in a state where the protection device fails.

4. When operating the equipment, the human body should try to avoid entering the range of motion of the equipment, except for maintenance.

5. Protective gloves must be worn when operating high-temperature equipment, and dust masks or face shields must be worn when operating equipment that produces gas or has dust drifting.

6. It is strictly forbidden to wear gloves when operating rotating equipment (such as bench drills, rotating machines, milling machines, winding machines), etc., and female employees should wrap or coil their hair in their hats when operating.

7. Before operating the equipment, check whether the button switches, rotary switches, indicator lights, indicator instruments, etc. are normal, whether they are damaged, and when they are turned on.

8. When starting the machine, according to the requirements of the product manufacturing process, open the valves of each pipeline, water pipe, oil pipe and other pipelines; Set the parameters of each working part of the equipment, and confirm whether the setting machine parameters are wrong and save before manufacturing products.

9. Manually operate the equipment for trial operation 2-3 to determine whether the water pressure, oil pressure, air pressure and temperature are within the range of the process requirements, whether the upper and lower parts of the installed abrasives are firmly fixed, whether the positioning hole locating pins are matched, and there are errors and deviations. Doing automatic cycle operation.

10. During the work, check from time to time whether the equipment parameters are out of the specified value, whether the screws and nuts in each part of the equipment are loose and falling off, whether the safety device is normal, and whether the equipment has abnormal sounds.

11. Turn off the switch valves of the equipment such as electricity, water, gas and oil after work; The cleaning site is clean and tidy.

12. Daily maintenance work:

• (1) Before operating the equipment every day, wipe the inside and outside of the equipment, the workbench, and the floor of the working area to keep it clean; Avoid oil stains to prevent slipping,

• (2) Whether the operating handles, switches, buttons, and emergency stops of the equipment are normal, and whether there is any damage or shortage.

• (3) Whether the operation of the operating system is sensitive and reliable, and whether there is abnormal sound of the equipment.

• (4) Whether the connecting rods, rotating shafts and bearings of each lubrication system of the equipment are maintained and lubricated.

• (5) Whether there is oil leakage, water leakage and air leakage in each oil line and pipeline.

• (6) Whether the protective safety devices of the equipment are complete and there is no malfunction.

• (7) Conscientiously do a good job in daily maintenance and make maintenance records.
