Airless Paint Sprayer is a tool that outputs kinetic energy to the outside world. In the process of use, it often produces some faults, which often hinder the progress of the work. Then, when a fault occurs, how to correctly find the cause to solve the problem?
 
Causes of non-stop failure
The switch does not bounce back: the valve stem is bent and rusted, the valve stem is damaged, deformed, the valve seat is damaged, and there is debris on the valve seat
Solution: Replace with new parts, replace with new parts and repair. Clear
 
Insufficient air when the switch does not move: The valve stem is bent or rusted. Poor piping
Solution: Replace the pipeline with new parts
The motor does not rotate: debris in the motor part, broken bearings, burned out
Solution: disassemble, refurbish and replace with new parts
 
Causes of air leakage
Does not turn, but there is air leakage from the vent hole: There is debris on the valve seat and the O-shaped rubber ring is damaged
Solution: Clear, repair and replace
 
Causes of low capacity failure
Weak motor rotation or poor sound: insufficient oil, worn bearings, fan blades, front and rear cover of the cylinder, worn or rusted rotors, burned out, etc.
Treatment method: oil injection, replacement of new parts, decomposition and refurbishment
 
Slow rotation: Low pressure, insufficient air flow, and wrong adjustment of the speed control knob
Solution: check and confirm
