What are the details of the pre-service training for employees of DC motor motor automatic oven baking machine?
The following are the details of the pre-service training for employees of DC motor motor automatic casing oven machine (for dispensing baking and drying):
1, the basic principles and structure of the equipment
l Explain the working principle of the DC motor, including how electrical energy is converted into mechanical energy to drive the operation of the oven machine, as well as the main structure of the motor such as stator, rotor, brushes (if any) and other parts of the role.
l Introduce the overall structure of the oven machine, such as heating chamber, ventilation system, temperature control system, transmission system (if any) and other parts of the location and function, so that employees have a full understanding of the equipment.
2、Operating procedure and standardization
l Preparation before starting: check whether there is any damage to the appearance of the equipment, whether the power connection is normal, whether the switches and buttons are in the initial state, and make sure that the inside of the oven machine is clean and free of foreign objects and residual dispensing.
l Detailed operating procedures: how to correctly set the temperature, time and other parameters of the dispensing drying, how to start and stop the oven machine, how to observe the operating status of the equipment in the process of operation, such as temperature changes on the display, the motor running sound is normal.
l Shutdown procedure: after completing the task of dispensing baking and drying, how to shut down the equipment in accordance with the order, including stopping the heating first, waiting for the equipment to cool down and then turn off the power, etc., as well as shut down the equipment after the finishing work, such as cleaning the door and the external surface of the oven, etc..
3、Precautions
l Electrical protection: Emphasize that the equipment must be well grounded to prevent electric shock. Inform employees not to touch the electrical components, such as motor terminals, heating element wiring, etc., in the cleaning or maintenance must first cut off the power supply and wait for the equipment to cool down completely.
l High-temperature protection: explain the oven machine in the operation process chamber and shell will reach high temperatures, employees must wear high-temperature protective gloves when operating, to avoid direct contact with high-temperature parts resulting in scalding. When opening the door of the oven, be careful of hot air spray, stand in a suitable position to operate.
l Mechanical protection: If there are transmission parts, such as belts, chains or gears, employees are reminded not to involve clothing, hair, etc., and not to approach the transmission area when the equipment is running.
l Chemical protection: Since it is dispensing baking and drying, involving glue and other chemical substances, inform employees of the characteristics of the glue, the possible hazards and the use of the oven machine in the process of fumes or odors generated by the treatment, such as to ensure that the ventilation is good, if necessary, wear protective masks, and so on.
4、Routine maintenance and maintenance knowledge
l Cleaning: Teach employees how to carry out daily cleaning of the equipment, including external wiping methods, internal chambers and components of the cleaning frequency and steps, such as regular cleaning of dust on the surface of the heating element, clear off the residual dispensing glue in the oven, etc., in order to ensure that the normal operation of the equipment and the heating efficiency.
l Simple troubleshooting: train employees to identify some common fault phenomena, such as abnormal temperature, motor does not turn, poor sealing of the furnace door, etc., and understand the initial troubleshooting methods, such as checking whether the power supply is normal, whether the temperature sensor connection is loose, etc., but emphasize that non-professional maintenance personnel shall not disassemble the equipment for in-depth maintenance without authorization, and report to the supervisor or a professional maintenance personnel when encountering complex faults in a timely manner.
l Lubrication (for related parts): If the equipment has parts that need to be lubricated, such as motor bearings, transmission chains, etc., teach the staff the correct lubrication method, the type of lubricant to be used and the lubrication cycle.
5、Emergency measures
l Sudden fire: train employees how to use the fire extinguishing equipment equipped near the oven machine, such as the fire alarm process, the use of fire extinguishers, and how to evacuate when a fire occurs.
l Equipment abnormality: When there are emergencies such as smoke, odor, abnormal sound or violent vibration in the equipment, teach the staff that they should immediately press the emergency stop button, cut off the power supply and quickly evacuate the scene, and at the same time, report the situation to the supervisor and wait for the professionals to deal with the situation.
