Air compressor "six first and six after " maintenance rules
Everything in the world has a regularity in everything.
For maintenance, there are also certain rules to follow.
These rules are summed up in practice by the great gods. Some old birds may already know or even remember them, but for some novices, the experience is very valuable and can help you to take some detours.
First check, then familiar
When the air compressor fails, the first thing to ask about the failure before and after the failure and the phenomenon of failure, just as the doctor consults the patient, the first thing to ask about the disease, in order to prescribe the right medicine.
According to the situation and clues provided by the user, the fault is analyzed (this is especially important for beginners), combined with the working principle of the air compressor and the function of each component, it is easy to know.
First sick, later special
According to the common characteristics of air compressors, common faults with universality and regularity are eliminated, and then special fault causes (including some uncommon component faults) are checked to gradually reduce the fault range from face to point. Reduce repair time.
First machine, outside machine
Compressor maintenance
For faulty air compressors, check the external components first, especially if some electrical switches outside the machine, the position of the knobs are proper, and whether the external power supply and controller settings are normal. Only after confirming that the external parts are normal, turn the machine on again for inspection. In particular, some environmental causes or induced failures must be well-informed and boldly assumed to be carefully verified.
Clean first, then repair
When inspecting the inside of the machine, it is important to check whether the machine is clean. If any oil, water stains, etc. are found between the components, components and pipes in the machine, it should be removed, observed and repaired. Reducing natural failures can achieve twice the result with half the effort. Practice has proved that many failures of air compressors are caused by "blocking" and "leakage", and the location of the fault can be more clearly detected by cleaning.
First mechanical, after electric
For some failures such as failure to start, failure to unload, and pressure failure, the probability of the fault occurring in the mechanical part is not very high, but it is necessary to spend a small amount of time to check the mechanical part. Only when it is determined that there is no obvious fault in each mechanical part, an electrical inspection is performed.
First static state, then dynamic state
The so-called static check is the check that is performed before the machine is not powered. When it is confirmed that the static check is correct, the power can be energized for dynamic check. If abnormal conditions such as smoke or flicker are found, you should turn off the machine quickly and perform a static check again. This will avoid powering up the machine when the situation is unclear, causing undue damage.
