The service life of an electric tray flipping machine depends not only on the quality and daily maintenance of the equipment itself, but also directly influenced by various factors in the usage environment. These environmental factors may accelerate equipment aging or cause malfunctions by corroding components, increasing mechanical loads, and interfering with electrical systems. The following is a detailed classification and specific impact mechanism of core environmental factors:

Humidity and moisture: causing metal corrosion and electrical short circuits

Wet environment is one of the core "natural enemies" of electric tray flipping machines, and its impact is concentrated in two aspects: metal structure and electrical system:

Corrosion of metal components: Metal components such as the main frame of the equipment, bearings of the flipping mechanism, chains, gears, etc. are prone to oxidation and rusting due to long-term exposure to high humidity or environments with water mist and dripping. Rust can cause an increase in the clearance between components, an increase in frictional resistance, which in turn can lead to flipping, jamming, and increased power loss. In severe cases, it can cause bearing jamming and chain breakage.

Electrical system failure: If electrical components such as motors, control cabinets, wiring terminals, sensors, etc. come into contact with moisture, they may damage the insulation layer, leading to short circuits, leakage, and even burning of motors or control modules. For example, in humid environments, the insulation resistance of motor windings decreases, which can easily lead to a "ground short circuit" and trigger overload protection shutdown. Frequent shutdowns can accelerate the aging of motor coils.

Dust and particulate matter: exacerbating mechanical wear and blockage

The environment with high dust concentration has a significant impact on equipment wear and blockage:

Mechanical component wear: Dust will enter the motion gap of the flipping mechanism, replacing lubricating oil to form "abrasives", leading to increased surface wear of the components. For example, after the gear tooth surface is worn by dust, there is a risk of "pitting corrosion" and "tooth breakage"; If dust is embedded in the inner and outer rings of the bearing, it will cause abnormal rotation noise, temperature rise, and shorten the service life by more than 50%.

Component blockage and functional failure: Dust is prone to accumulate on motor cooling holes, control cabinet ventilation openings, limit switch contacts, or sensor probes:

Blocking the heat dissipation holes of the motor can lead to poor heat dissipation. The motor operates at high temperatures for a long time, accelerating the aging of the coil insulation layer and even burning it out;

The contact of the limit switch is covered with dust, which may cause signal transmission failure and pose safety hazards such as "over flipping" and "inaccurate positioning" of the equipment.

Abnormal temperature: affecting the performance of the motor and lubrication system

Excessive or insufficient temperature can exceed the normal operating threshold of equipment components, leading to performance degradation:

High temperature environment:

Decreased motor efficiency: The resistance of the motor winding increases with the increase of temperature, resulting in a decrease in output power and an increase in heat dissipation pressure. If the fan or heat sink fails, it is easy to trigger the "overheat protection" shutdown, and frequent starting and stopping will accelerate the aging of the motor;

Lubricating grease failure: The lubricating oil and grease used in the flipping mechanism will become thinner and more fluid at high temperatures, losing their lubricating effect, resulting in "dry friction" of metal parts and a significant increase in wear rate.

Low temperature environment:

Solidification of lubricating grease: Low temperature can increase the viscosity and even solidify the lubricating grease, resulting in a sharp increase in the rotational resistance of the flipping mechanism, and the starting load of the motor exceeding the rated value, which may cause "stalling" and burn out the motor;

Decreased performance of electrical components: Capacitors, relays, and other components inside the control cabinet will have reduced capacity at low temperatures, resulting in increased contact resistance and potential delay or failure of control signals, leading to decreased stability of equipment operation.

Corrosive gases/liquids: accelerate the degradation of metals and electrical components

In environments such as chemical workshops, electroplating workshops, and food pickling areas, there are corrosive gases or liquids that have the characteristics of "strong concealment and thorough damage" to equipment

Corrosion of metal structures: Corrosive media can directly damage the metal coating of equipment frames and flip arms, thereby corroding the substrate and causing a decrease in structural strength. In severe cases, it can lead to "perforation" and "fracture", causing safety accidents;

Deterioration of electrical system: If corrosive gases or liquids infiltrate the motor or control cabinet, they will corrode the insulation paint of the motor winding and the metal contacts of the wiring terminals, leading to a decrease in insulation performance, contact oxidation, and ultimately causing short circuits or signal failures.

Vibration and Shock: Damaging Component Connections and Accuracy

If the electric tray flipping machine is installed in an area with frequent vibrations or subjected to frequent impacts during operation, it will indirectly shorten the equipment life:

Loose connection of components: The bolts and nuts of the equipment will gradually loosen under long-term vibration, resulting in component misalignment, "abnormal noise" when flipping, and a decrease in positioning accuracy;

Damage to precision components: Precision components such as motor bearings and gear reducers, if subjected to vibrations or impacts beyond the design range for a long time, may experience "fatigue damage". These damages are difficult to detect in the early stages and can suddenly cause equipment failure in the later stages, resulting in extremely high maintenance costs.

Targeted protection recommendations

In response to the above environmental factors, the following measures can be taken to reduce the impact:

Humidity/Moisture Protection: Install rain shelters and dehumidifiers in damp areas; The motor and control cabinet adopt models with a waterproof rating of IP54 or above, and waterproof sealant is applied to the wiring terminals;

Dust protection: Regularly clean the motor cooling holes and limit switch contacts; In environments with high dust concentration, install dust covers for equipment and install "dust filters" on the ventilation openings of control cabinets;

Temperature protection: Install sunshades or forced cooling fans in high-temperature environments, and use "high-temperature motors"; Use "low-temperature special lubricating grease" in low-temperature environments, and preheat the equipment before starting;

Corrosion protection: Select equipment components made of stainless steel material; Regularly spray anti-corrosion paint on metal structures and perform "sealing treatment" on electrical cabinets to prevent the infiltration of corrosive media;

Vibration protection: Install shock-absorbing pads during equipment installation; Avoid overloading operation, adjust the flipping speed to a reasonable range, and reduce inertial impact.

By avoiding or mitigating the impact of the above environmental factors, the frequency of equipment failures can be effectively reduced, and the actual service life of the electric tray flipping machine can be extended.
