Air compressor temperature has been rising for the following reasons:
poor ventilation and heat dissipation around the air compressor. It may be that there are other heat sources around the air compressor, which causes the fan to fail to form a strong airflow, so that the air compressor temperature is too high.
The environment around the air compressor is dusty. This will cause a layer of dust to adhere to the surface of the radiator, and the internal is also easy to block and affect the heat dissipation, resulting in the temperature of the air compressor after the radiator is blocked.
The oil filter in the compressor is too dirty. The resistance oil cannot enter the compressor normally, so that the cooling oil is not enough and the temperature rises rapidly, resulting in the air compressor temperature being too high.
The air compressor adopts special compressor oil. If other oil with low label or poor quality is used, the back viscosity and specific heat will not reach the standard, resulting in excessive temperature.
The fan tape is cracked or loose. This will reduce the speed of the fan rotation, affect its heat dissipation effect, resulting in the air compressor temperature is too high.
Oil/gas separator core is too dirty. When the oil and gas separator core is too dirty, the oil will affect the circulation due to excessive resistance, resulting in overheating and shutdown.
Exhaust pressure exceeds rated pressure. Long-term operation causes the compressor and the diesel engine load to be too heavy and heat up, resulting in the shutdown of the air compressor and the temperature is too high.
Low cooler efficiency, lubricating oil aging failure, oil temperature sensor failure and poor coordination of moving parts may also lead to excessive temperature.
Problems such as insufficient oil volume of the air compressor, dirty oil cooler, blocked oil filter core, oil control valve failure (component damage), rupture or aging of the diaphragm of the oil cut-off solenoid valve, fan motor failure, cooling fan damage, poor exhaust pipe or high exhaust resistance (leeward), ambient temperature exceeding the specified range, and temperature sensor failure may also cause the temperature of the air compressor to rise.
To solve the problem of air compressor temperature rise, it is necessary to investigate the above possible causes one by one, and take corresponding maintenance measures.
The choice of frequency conversion and power frequency in screw air compressor depends on the specific use scenario and demand. The following is a comparative analysis of their respective advantages and disadvantages for reference: the advantages of frequency conversion screw air compressor: the energy-saving effect is remarkable: the frequency conversion screw air compressor passes through the frequency converter
The oil content of the compressed air of the oil-free air compressor can reach level 0. According to industry standards such as ISO 8537-1 or ISO 8573-1, Class 0 requires an oil content of less than 0.01 mg/m & sup3;, which is usually considered equivalent to the oil content grade of oil-free compressed air.
Large air compressors play an indispensable role in a variety of scenarios, and their wide application is mainly reflected in the following aspects: Industrial manufacturing: In automobile manufacturing, machining and other industries, large air compressors are various pneumatic Tools provide power, such as pneumatic wrenches
The water content standard of compressed air varies according to the application scenario. The core is to control the moisture content in the air to avoid adverse effects on equipment, products or processes. The following is a brief description of the relevant standards: Key indicators of water content: dew point temperature Moisture in compressed air
The maintenance of oil-free high-pressure air compressor mainly includes the following aspects: daily cleaning and maintenance: basic daily cleaning and maintenance should be carried out every day, including dust removal, floating ash, etc., to keep the air compressor and its surrounding environment clean. Clean environment can greatly reduce the machine
The variable frequency air compressor does not continue to run in a fixed state, but realizes dynamic adaptation through intelligent adjustment. After Granklin water-lubricated single screw air compressor is combined with variable frequency drive technology, its operation logic can be summarized as the following characteristics: 1. Adjust on demand to avoid invalid operation
Oil-injected oil-free air compressors are different from traditional oil-free air compressors in terms of working principle and structure, so they each have unique advantages and disadvantages. The following is an analysis of the advantages and disadvantages of oil-injected oil-free air compressors: Advantages: Good lubrication effect: oil-injected oil-free
The oil content standard of compressed air in air separation units usually varies according to different industries and application fields. The following is a clear summary of the standard for the oil content of compressed air in air separation units based on the information provided in the reference article: ISO 8573 Standard:
Screw air compressors are indeed divided into two types: variable frequency and fixed frequency. There are significant differences between the two in motor speed control, energy consumption management, application scenarios, etc. The specific analysis is as follows: 1. Variable frequency screw air compressor Working principle Real-time via frequency converter
Compressed air oil content standards vary by application and industry. The following are some common oil content standards for compressed air: Chinese Pharmacopoeia and GMP standards: require compressed air oil content ≤ 0.1 mg/m & sup3;. This standard is from the European Pharmacopoeia regulations.
