Horizontal sand mill in the production process of the operation process and its precautions
Horizontal sand mill as a kind of important equipment widely used in chemical industry, paint, pigment and other industries, its operation procedure and precautions are of great significance to ensure the normal operation of the equipment, improve the production efficiency, and ensure the operation safety. This article will introduce the operation process of horizontal sand mill and its precautions in detail from the aspects of preparation before start-up, start-up operation, precautions before use and equipment maintenance.
Preparation before start-up
Before starting the machine, the operator needs to do the following preparations.
1. Open the cooling water valve to ensure that the cooling system operates normally to prevent the equipment from being damaged due to overheating.
2.2. Check whether the cleaning liquid is clear and the amount is sufficient. If the cleaning fluid is not clear or the amount is insufficient, it should be replaced or added in time. For 15 liters of sand mill, also need to check whether the drive solvent pump small belt is intact.
3. according to the equipment type and production requirements, select the appropriate cleaning fluid. 30 liters of sand mills require the use of ethanol as a cleaning fluid, while 15 liters of sand mills depending on the situation. 4. if the sand mill downtime of more than 24 hours, the operator should manually open the belt guard before starting the pulley, repeatedly rotate the pulley for 10-15 times to ensure that there is no foreign matter inside the equipment, to avoid malfunctions when starting the machine.
Start-up operation
After ensuring that the preparatory work is completed, the operator can follow the following steps to start the operation.
1. Close the magnetic starter front pole iron shell switch (outdoor), press the wall button (green) to turn on the power. Note, before pressing the button to ensure that the magnetic starter has been in a normal state, in order to avoid power short-circuit or other failures. 2. Start the dynamic pump motor, to be discharged out of the mouth of the material outflow, and then start the main motor. Generally not allowed to start the main motor empty, so as not to cause damage to the equipment.
3. In the sand mill working process, the operator should always pay attention to the working status of the equipment, mainly pay attention to the thermometer pressure gauge and adjust the pump speed. If abnormalities are found, the machine should be stopped immediately and notify the relevant personnel for inspection and maintenance.
Third, the precautions before use
Before using the horizontal sand mill, the operator needs to pay attention to the following matters
1. Check whether the mechanical and electrical parts are normal, including lubrication points, transmission devices, connecting bolts and so on. Ensure that all parts are intact, lubrication is normal, and the transmission device runs smoothly.
2. Check whether the protective device is intact, whether the contact of motor carbon brush is good, whether the electrical instrument is sensitive. Ensure that the equipment is safe and reliable during operation.
3. Coil the car for a week, check the rotating part of the equipment or around any obstacles. Ensure that the equipment will not fail due to collision with obstacles during startup.
4. When starting the surrounding can not stand people. In order to avoid the occurrence of accidents on the personnel caused by injury.
5. After checking, start the motor and pay attention to the current change. Observe whether the motor is running normally and whether the current is within the rated range.
