Failure analysis of pneumatic tools

There are many problems with the pneumatic tools of the pneumatic tool manufacturer. Let's look at the cause of the failure.
Pneumatic tool is the first choice of many manufacturers, but do you know what to do if the pneumatic tool breaks down? The following is to introduce several fault causes, hoping to play a role for you.
Causes of failure of pneumatic tools
1. Motor does not rotate: sundries are mixed in the motor part, bearing is damaged and burnt
Handling method: disassemble, repair and replace new parts
2. Inadequate air when the switch does not work: valve stem is bent, rusty and poor piping
Treatment method: replace the parts and repair the pipeline
Causes of air leakage
1. No rotation, but air leakage from the exhaust hole: sundries on the valve seat and O-ring damage
Treatment: cleaning, repair and replacement
Cause of low capacity failure
1. Slow rotation: low pressure, insufficient air flow, wrong adjustment of speed control knob
Handling method: inspection and confirmation
2. The rotation force of the motor is weak or the sound is poor: the oil is insufficient, the bearing is worn, the fan blade, the front and rear cover of the cylinder, the rotor is worn or rusted, burnt, etc
Treatment method: oil injection, replacement, disassembly and repair of parts
Cause of non-stop rotation failure
1. Switch does not jump back: valve stem is bent, rusty valve stem is damaged, deformed valve seat is damaged, and valve seat has sundries
Treatment: replace with new parts, repair and remove
The introduction of so much knowledge about pneumatic tools' faults can help you to use pneumatic tools more safely. As long as the maintenance of pneumatic tools is done properly, the faults can be handled in time.
