Electrostatic spraying production line equipment maintenance
In order to effectively keep the equipment of the electrostatic spraying production line running well, the daily maintenance is the maintenance of the equipment of the electrostatic spraying production line. In order to effectively keep the electrostatic spraying production line equipment in good operation and ensure the normal operation of the equipment, we often receive customer inquiries about the operation of spraying equipment. Through long-term answers, it is found that more than 90% of users are because Usually the maintenance and protection work is not good, and the active spraying equipment is in a situation where it cannot be used to continue the operation. Therefore, even when the production operation is very busy, we must squeeze some time to do the maintenance and protection work for the equipment. Next, we will introduce how to maintain the electrostatic spraying production line equipment during the coating production process.
1. Daily maintenance of electrostatic spraying production line equipment
1. Distribution box: Check that the display lights, buttons and dashboard of the distribution box should be intact and in all normal working attitudes; there is no metal material or any dirt that is not related to machinery and equipment in the distribution box, check Whether the route is damaged, various electrical components are set properly, and the operation should be normal.
2. Cleaning organization: check whether the pipeline is leaking, whether the motors and centrifugal pumps of the water circulation system are noisy, the motor's ambient temperature is detected, and everything should be normal during the operation of the top exhaust fan.
3. Air-drying and dry-solid curing furnace: check the working attitude of the burner, whether the centrifugal fan of the circulation system is noisy, check the ambient temperature of the motor, and everything should be normal during the operation of the top exhaust fan.
4. Conveyor belt: check whether the drive equipment motor is loud, temperature test, and the triangle belt is not damaged; check the operation of the reducer, check the remaining oil in the oil, check the toothing of the transmission gear and the transmission chain, and there must be no deposit transmission Chain condition; check the lubrication condition of the transmission chain. If the transmission chain is found to be dry, it should be filled with heat-resistant lubricating automobile oil immediately.
5. Check the lubrication condition of the horizontal and vertical slide rails of the spray guns on both sides, check the working pressure of the refrigerated dryer and the heat pipe radiator.
2. Monthly maintenance of electrostatic spraying production line equipment
1. Distribution box: Clean the distribution box on time, tighten the terminal blocks, check the posture contact points of AC contactors, automobile relays, etc., whether there is crevice corrosion, repair poor products or replace new products.
2. By itself: use a megger to test the grounding resistance of the motor with three phases to the ground on time to eliminate common faults of motor-to-ground short-circuit faults to prevent risks; use a clamp-on ammeter to check the balance of the three-phase motor current to prevent The motor is endangered when the motor is in open phase; the pipeline is checked for looseness and tightened immediately; the pump casing and transmission organization are filled with unsalted butter to reduce damage; the burner should be removed on time to clean the dust.
3. Conveyor belt: the drive reducer should be dismantled and replaced on time (150# oil), the balance weight and the tensioning mechanism should be adjusted to ensure that the tensioning organization can be expanded and contracted freely; Excellent chain lubrication.
4. The paint spray gun organizes the slide rail to clean the dust and lubricate; the refrigerated dryer radiator cleans the dust.
