The polishing machine is suitable for automatic polishing and metal grinding and deburring. Lightweight, ergonomic design for easy one-handed control; variable speed control allows users to easily adjust the speed according to different applications; the pneumatic polishing machine is often used, and you will inevitably encounter it during use some problems. Here are a few common problems:
1. The main machine of the pneumatic polishing machine makes an abnormal noise or does not move up or down
2. The pneumatic polishing machine has a collision accident
3. The rocker arm of the pneumatic polishing machine is broken
4. The pneumatic polishing machine cannot be started
The main reasons for such failures are damage to the lifting motor of the pneumatic polishing machine; serious wear and tear on the driving system of the lifting screw nut; the screw nut is disconnected; foreign matter such as stone dust is stuck on the column; the clearance between the lifting slide and the column Too small, the resistance is too large; the bearing on the lifting screw is damaged, etc.
It is recommended to take the following treatment methods: replace the new pneumatic polishing machine lifting motor; first, rotate the motor without load to check whether it is qualified; check the lifting screw and screw nut, repair or replace; remove the dust and other foreign objects of the lifting column; adjust reasonably The clearance between the lifting slide and the column; replace the damaged bearing,
The main reasons for this failure are: the lift travel switch on the column is open, short-circuited or poorly contacted, causing failure; the iron core of the intermediate relay AC contactor fails due to residual magnetism or dirt adhesion; the travel switch position is adjusted improperly or tightly It's not solid.
It is recommended to take the following treatment methods: check the pneumatic polishing machine stroke switch and related lines; disassemble the AC contactor of the intermediate relay, wipe off the dirt on the iron core, and check whether the parts are jammed and remove or replace with a new one Components; re-adjust the position of the travel switch and tighten the bolts; regularly remove dust from the components in the electric control box.
The main reasons for this accident are the unreasonable structural design of the rocker arm section of the pneumatic polishing machine, and insufficient strength; during transportation, the cantilever end was not fixed properly, and impact and breakage occurred; during the shutdown and maintenance process, the cantilever end was not properly cushioned. Support, receive a big impact, cause breakage.
It is recommended to take the following treatment measures: check and verify the rationality and strength of the rocker arm section structure to meet the requirements; carry out equipment transportation reasonably and safely; when the machine is not in use or for maintenance, use stones or sleepers to cushion the grinding head body at the cantilever end to prevent damage Equipment and personal accidents occur due to man-made shocks.
The main reasons for such failures are: poor contact or damage to the fuse in the main motor control circuit of the pneumatic polishing machine; the stator and rotor windings of the motor are grounded, and the bearing is damaged; the main motor is damaged or the purchased main motor fails to pass the no-load inspection.
It is recommended to take the following treatment methods: re-tighten or replace the circuit breaker; run at no-load first, observe whether the pneumatic polishing machine motor is working normally, and then check whether it needs to be replaced
