Common breakdowns and maintenance of machines BY and BG series coating machine

1, the new machine is not running: for this reason most of the circuit breaker is not open, as long as the open circuit breaker can; there is a phenomenon in the process of transportation bumps resulting in thread off, at this time the need to open the cabinet door or machine check ground is ok.

2, for the wind or no wind volume adjusting knob: unable to open or open in the end. When the air supply is turned on, the adjusting knob should be turned clockwise. At this time the air volume will be the maximum. The knob will turn clockwise. The air volume will gradually decrease to the stop (after the fan stops, it will damage the heater easily).

3, oil spills:

A) oil seal wear, replace the oil seal. Methods: the lubricating oil in the speed reducer is discharged, remove the triangle belt, belt wheel reducer with Lamar will remove the pulley end bearing seat is removed, the other end of the bolt is loosened, with an iron bar, a speed reducer, and then remove the bearing cover, replacement of the oil bearing cap, finally in order. Can.

B) oil leaks at the oil window. The reason is that the oil window is deformed or damaged. Methods: remove the oil window gland, remove the damaged oil window, replace the new oil window. Pay attention to the oil window and observe the damage of the O ring after the oil window. If there is any damage, replace the O ring of the same type.

(C) the joint of the bearing cap and the reducing case body leaks oil. The reason is that in the replacement of oil seals or oil window, the shaft shoulder O - ring damage. Remove the bearing cap in sequence and replace it with the O ring of the same type.

D) leaking oil at the oil drain bolt. Remove the bolts, wrap them around the tape and fill them with liquid sealant.

4, pot rotation weakness:

A) V-belt slippage. Methods: loosen the motor bottom plate fixed bolt, the motor down, adjust the triangle belt tightness (thumb press the triangle belt surface, distance is less than 15mm), tighten the fixed bolt. If the V-belt is worn badly, replace.

B) worm and worm wear. Method: remove the pan, inner heating parts, outer panel and frame, take out the reducer and replace it. When replacing the installation sequence, all parts of the split: worm gear shaft bearing cover, bearing seat, even out to remove the worm gear worm shaft worm gear worm bearing replacement, both ends of cover to remove the worm remove bearing replacement, installation and removal in reverse order.

5, reducer abnormal sound: A) worm gear wear, the method is the same as 4B. B) bearing damage. The replacement method is the same as that of 4B.

6, No: A) for heating hot air blower is not open, because of air supply fan and the heating linkage is, for the wind does not open, internal heating does not work; B) such as air supply has been opened but no hot air, you should check the heating pipe thread is loose, the wind speed adjustment knob is opened in the end (open the air supply switch before the first wind speed adjusting knob to maximum volume) or the heating pipe is burned; C) fan switch and speed adjusting knob has been opened, the heating tube is also work, but without blowing hot air, this phenomenon is caused by two reasons, one is the fan fan electrical wiring loose or volume this situation needs to be burned, or to the capacitor thread reconnection replaced by the same type. The two is the wind shaft does not turn, this phenomenon is due to the lack of oil in the wind shaft leading to death, the processing only need to remove the fan and wind casing, add lubricating oil in the rotating shaft parts, or replace the fan.
