Everything in the world has laws. For maintenance, there are also certain rules to follow.

These rules are summed up by the maintenance God in practice. Some old birds may have known or even memorized them, but for some novices, experience is still very valuable and can help us avoid some detours.

When the air compressor fails, first ask the process before and after the failure and the failure phenomenon, just like a doctor consulting a patient, first ask the patient's condition, and then prescribe the right medicine.

According to the situation and clues provided by the user, analyze the fault (this is especially important for beginners), and combine the working principle of the air compressor and the functions of various components to achieve a clear understanding and a targeted goal.???

Common diseases first, then special ones

According to the common characteristics of air compressors, common faults with universality and regularity shall be eliminated first, and then special fault causes (including some unusual component faults) shall be inspected to gradually reduce the fault scope, from surface to point and shorten the repair time.

First outside the aircraft, then inside the aircraft

For the air compressor with fault, check whether the external components, especially some electrical switches and knobs outside the machine are in proper positions, and whether the external power supply and controller settings are normal. Only after confirming that the external parts are normal can the machine be opened for inspection. In particular, the faults caused or induced by some environments should be well known, bold assumptions and careful verification.

Clean first and repair later

When inspecting the inside of the machine, it is necessary to focus on whether the machine is clean. If additional oil and water stains are found between the components, parts and pipelines in the machine, they should be removed, observed and then repaired. In this way, natural faults can be reduced and twice the result can be achieved with half the effort. Practice has proved that many faults of air compressor are caused by "blockage" and "leakage", and the fault location can be found more clearly through cleaning.

First mechanical, then electrical

For some faults such as failure to start, failure to unload, and failure to go up the pressure, the probability of failure in the mechanical part is not very high, but it is necessary to spend a little time to check the mechanical part first. Only when it is confirmed that there is no obvious fault in each mechanical part, the electrical inspection shall be carried out.

First static, then dynamic

The so-called static inspection is the inspection before the machine is powered on. Only when the static inspection is confirmed to be correct can power on for dynamic inspection. In case of smoke, flicker and other abnormal conditions, shut down the machine quickly and conduct static inspection again. This can avoid powering up the machine when the situation is unknown and causing undue damage.
