Wooden door grinding machine mechanical common faults of analytic solution

Many machines used long live sometimes appear such as fault, take wood mechanical polishing machine, for instance, often have three failure occurs, what we see now is three kinds of fault and its solutions respectively what! ! ! ! A & middot; The common malfunction 1 wood mechanical polishing machine. Idling speed did not change, when grinding things slow down or stop when I was 2. Card dead, the motor had no reaction. 3. His turn yourself run 2 & middot; The principle of the general faults of wooden door grinding machine mechanical one. Pneumatic grinding machine in quantity can not meet the minimum working pressure, or pressure fast shut not fully open, the cylinder wear and tear, improper proportion of sand plate and block, or between the bearing wear. 2. Air can't normal into the motor internal, there are pieces of card between the rotor and cylinder. 3 valve switch is broken, or a foreign body has caught. Three & middot; To deal with failures of several kinds of method 1. Clean up the air inlet of foreign bodies, or improve the gas flow rate and pressure switch to adjust to switch up; Replace the valve pin; Replace the cylinder; Replace the cylinder cover; Replace the bearing. 2, change the eccentric block bearing; Replacement of eccentric block, the original sand tray; Eccentric block and bearing need to be replaced; Replace the valve pin spring; Removing debris or replace packers. 3, motor to see if there is air into the; Replace the new blade; Replace the bearing;
