In the use of the extruder, it is inevitable that we will encounter some problems. Many times, as long as we understand some problems, where the problems are, we can avoid some unnecessary troubles. Today Xiaobian has organized two extrusion presses for everyone. Exhaust problems, let us take a look together
1. Why does the extruder exhaust fail to meet the standard discharge pressure?
Look at what way to control the exhaust, if it is using pressure relay, you can increase some of the appropriate, if you use the pressure transmitter, in the man-machine interface, modify the exhaust pressure can be adjusted. Mainly for the once normal extruder, if it is a new machine, there may be procedural issues.
2. Why is there a strange noise when the extruder exhausts?
This is a problem with the gearbox. Transmission abnormal sound is more complicated, because of different causes of failure, the sound is not the same, generally divided into gear and bearing ring.
Causes of abnormal noise: 1. The bearing is loose and loose; 2. The ringing of the gear is due to the loud noise caused by the gear meshing clearance being too large or too small, or due to the low accuracy of the gears during manufacturing, and abnormal sound; 3. The dry grinding due to lack of oil sound.
How to determine: 1, whether the transmission is partially or overheated, yes, lack of oil or bite; 2, when the neutral sound is heard, after the clutch pedal to eliminate the sound, generally the first axis of the front and rear bearing wear looseæ—· Or constantly meshing gears, such as changing into any gear, mostly the rear bearing of the second shaft rings, and should be repaired or replaced for seriously loose or damaged bearings.
