Structural features
Direct transmission: the power of the motor is directly transmitted to the machine head through the elastic coupling, with fewer transmission links, less energy loss, and high transmission efficiency, up to 98%-99%
Low speed: The speed of the direct-coupled screw air compressor is relatively low, generally between 1500-3000 rpm, which makes the compressor have less wear, long life and high reliability
Compact design: The overall structure is compact, small in size, light in weight, easy to install and handle
Low noise: The use of advanced noise reduction technology, such as sound insulation cover, muffler, etc., makes the operation noise of the air compressor low, generally between 60-80 decibels
Fields of application
Industrial production: widely used in machinery manufacturing, automobile maintenance, electronic appliances, food and beverage, pharmaceutical and other industries, to provide compressed air for various production equipment, such as pneumatic tools, pneumatic valves, cylinders, spraying equipment, etc
Architectural decoration: It can be used for painting, spraying, pneumatic nail gun, air picks and other operations in building construction, as well as painting and gluing in home decoration
Healthcare: In the medical field, 3P direct-coupled air compressors can be used for air supply for dental equipment, medical pneumatic tools, ventilators, and other equipment
Other fields: It can also be used in mining, metallurgy, chemical industry, textile, printing and other industries, as well as some special occasions that require compressed air, such as diving, fire fighting, aviation, etc
Maintenance
Replace the lubricating oil regularly: The lubricating oil is one of the important factors to ensure the normal operation of the air compressor, and the lubricating oil should be replaced regularly according to the instruction manual and working environment of the air compressor, generally every 1000-2000 hours of operation or every six months
Clean air filter: The function of the air filter is to filter impurities and dust in the air to prevent it from entering the air compressor and affecting the normal operation of the air compressor. The air filter should be cleaned regularly, generally every 200-300 hours of operation or once a month
Check the tightness of the belt: For the air compressor with belt drive, the tightness of the belt should be checked regularly to ensure the transmission efficiency and service life of the belt. Typically every 100-200 hours of operation or quarterly
FAQ
Q: What is the power of the 4P direct-coupled air compressor and what scenarios are it suitable for?
A: 4P stands for 4 horsepower, and 1 horsepower is about 0.7457 kilowatts, so the power of the 4P air compressor is about 2.98 kilowatts, and 3 kilowatts are generally taken. It is suitable for small enterprises and workshops, and can drive pneumatic tools such as small painting equipment, air nail guns, air batches, etc., and can also supply pressure to small instruments such as dispensing machines, and can also be used for dust blowing, small car inflation, home improvement and repair shop operations.
Q: What are the advantages of direct-coupled air compressors compared with other transmission air compressors?
A: The direct-coupled air compressor connects the motor directly to the machine head through an elastic coupling. The advantage is that almost no energy is consumed in the drive and the drive efficiency is 98 to 99 percent. Except for the elastomer that is replaced every 3 years or so, the coupling requires little maintenance and is easy to replace the elastomer without disassembling the head, tubing and valves. At the same time, the speed of the direct-coupled screw air compressor is low, which makes the life and reliability of the equipment higher.
Q: What is the normal pressure range of a 4P direct-coupled air compressor?
A: The normal pressure range of 4P direct-coupled air compressors is typically 0.7-0.8MPa (7-8 kg), which is the standard air pressure range for most industrial scenarios. The specific pressure value may be slightly different due to the brand or model, the rated working pressure can be confirmed through the equipment pressure gauge or manual, and it is recommended that the maximum pressure value marked by the equipment (generally ≤ 1MPa) when used to ensure safety and equipment life.
