When an air compressor overheats, the problem is usually related to factors involving irregular suction or discharge pressure. Alternatively, the problem could be due to insufficient ventilation, eroded oil, or any given number of problems related to wear on machine parts. The most common cause of an air compressor shutting down is overheating. As temperatures rise, air compressors are especially prone to overheating.
This is partly due to an increase in the amount of water vapor in the air. Heat and humidity combined can cause problems for any piece of machinery. The reason for the overheating could be that the ambient temperature has exceeded the maximum operating temperature of the compressor, although in reality this is not the most likely reason for an air compressor overheating. A dirty radiator, low oil level, or mechanical problems within the air compressor system could be the real cause of excessive heat.
The good news is that the most common reasons behind an air compressor overheating can be avoided with routine maintenance and daily monitoring. Another common cause of overheating is that the compressor doesn't have enough oil. Always check oil levels regularly and change the oil in your compressors regularly. If you don't add or change the oil, the oil can become varnished and cause too much friction, which can lead to overheating or a possible fire.
The most common reason for an air compressor overheating is the surrounding hot temperature and the warmer environment it is in. Make arrangements to keep the air compressor close to direct sunlight in midsummer. Avoid keeping any hot equipment near compressors. Build an appropriate insulation system in case of limited space.
All of these configurations are avoidable problems in maintaining a lower temperature in the surrounding environment. Try to keep the air compressor away from windows, especially in hot weather, and don't let the air compressor sit next to other operating equipment that can get very hot. Low suction pressure generally results in a high compression ratio. When the compression ratio increases, it means that a certain volume of air and fuel in the cylinder is compressed into a much smaller space, creating higher discharge temperatures.
Extremely high discharge pressure is an indicator that there is not enough refrigerant in the system. Without an adequate amount of coolant, there is no substance to cool the machine, which causes overheating. If the compressor takes longer between cycles, internal parts may take longer to cool down between processes. For example, if compressors show performance problems only a few times after the last check.
Air compressor overheating as a result of excess discharge pressure, which typically comes from one or more of the categories listed:. An air compressor space with precise air flow provides fantastic air for the air compressor inlet. Understanding the cause of vibration and how to resolve it will be critical to keeping the compressor in good working order. If my guesses are correct, then the copper tube is the one that pumps compressed air from the compressor pump into the tank through a check valve.
During installation, make sure the compressor is placed in a suitable location and regularly clean the compressor vents over time. The air contains more moisture as the temperature increases, so this problem tends to arise quickly in summer. The compressor will generate air and shut down well and restart well, it heats up so much in the check valve that I can barely use it. Another concern that should be checked immediately is the amount of ventilation available to the air compressor.
The thermal valve opens once the oil heats up to allow compressor oil to flow through the cooler or radiator. Keep the compressor away from windows, especially in hot weather, and don't allow the compressor to be placed next to other operating equipment that can get very hot. One of the main reasons why an air compressor can overheat is a high compression ratio, which is naturally due to a low level of suction pressure. For best air compressor performance, the temperature in the discharge line should never exceed 107⁰C.
