What are the contents of pre-service training for employees of DC motor motor semi-automatic spring brush machine?
Pre-job training for employees operating the DC motor motor semi-automatic spring brush machine can ensure that employees operate the equipment correctly, the training content should cover theoretical knowledge, operating skills, specifications and maintenance and other aspects:
1, the basic knowledge of the equipment
Working principle: explain in detail the working principle of DC motor, including the law of electromagnetic induction, the law of amperage in the application of the motor, so that employees understand how the motor will be converted into mechanical energy to drive the brush machine work. Introduce the semi-automatic spring brush machine to realize the good contact between brush and commutator with the help of spring device, and how to realize the functions of motor start-stop and speed adjustment through the control system.
Structural Composition: Introduce the structure of each part of the brush machine, such as the stator, rotor, brush, commutator and other parts of the DC motor, as well as the brush head, spring assembly and transmission mechanism of the brush machine device, through the disassembled diagram or physical display of the equipment. This will enable the employees to understand the function of each part and the connection relationship between them, and lay the foundation for the subsequent operation and troubleshooting.
2、Operation standardization process
Power on and off: Train the staff on the correct power-on sequence, such as turning on the power first, observing whether the control unit display shows normally, and then start the motor. When shutting down the machine, it is necessary to operate according to the order of stopping the motor running first and then turning off the power to avoid damage to the equipment due to improper operation.
Parameter setting: Teach employees how to set appropriate parameters according to different brushing tasks, including motor speed, brushing time, spring pressure, etc. Explain in detail the impact of each parameter on the brushing effect, such as too high a speed may lead to increased wear and tear of the brush head, too little spring pressure can not ensure good brushing quality, etc., so that employees can learn to make reasonable adjustments according to the actual situation.
Operation steps: Conduct on-site demonstration to show employees the whole operation process from preparation (e.g. installing suitable brush head, checking the status of the equipment) to the formal brushing operation (e.g. placing the workpiece in the right position, starting the brushing process), and then finishing the work (e.g. cleaning up the equipment, organizing the tools). Require employees to practice the actual operation to ensure that they are proficient in the operation steps.
3、Precautions
Electrical protection: Emphasize electrical protection during the use of the brush machine, such as precautions to prevent electric shock, including do not operate the equipment in a humid environment, avoid contact with electrically charged parts, and so on. Introduce how to correctly identify and deal with electrical faults, such as smoke, odor or abnormal sound, should immediately cut off the power supply and report to the superior.
Mechanical protection: Explain the possible dangers posed by the operating parts of the machinery, such as entrapment that may be caused by transmission belts, chains and other parts. Require employees not to touch these running parts when the equipment is running, and must ensure that the motor is completely stopped before equipment maintenance.
Protective measures: Teach employees to properly wear personal protective equipment, such as goggles and gloves, to prevent injuries such as debris splash and mechanical damage during the brushing process. At the same time, ensure that the work area is well ventilated to avoid health effects due to prolonged inhalation of dust generated by the brushing machine.
4、Fault identification and initial processing
Common failure phenomenon: Introduce the common failure phenomenon of brush machine to employees, such as motor does not rotate, unstable speed, brush sparking, poor brushing effect, etc., so that employees can find abnormalities in the work in time.
Initial troubleshooting methods: Train employees in some simple troubleshooting methods, such as checking whether the power connection is normal, whether the brushes are badly worn, whether the brush head is firmly installed, etc. Teach employees in the discovery of faults, should be the first to carry out these basic checks, such as can not solve the problem, should be reported to the maintenance staff in a timely manner, and shall not be unauthorized dismantling of equipment for maintenance.
5、Maintenance knowledge
Daily maintenance: Instruct employees to do a good job of daily maintenance of the equipment, including cleaning the dust and debris on the surface of the equipment, check the wear and tear of the brushes and commutator, to ensure that the transmission components are well lubricated and so on. Emphasize the importance of routine maintenance to extend the service life of the equipment and ensure the normal operation of the equipment.
Regular maintenance: Introduce the items and cycles of regular maintenance of equipment, such as regular replacement of brushes, lubrication of bearings, checking the insulation of the electrical system. Let employees understand the work content and requirements of regular maintenance, and how to cooperate with maintenance personnel to carry out regular maintenance of equipment.
