The service life of the air compressor tank (I. e. gas tank) is usually 10 years, but this value is not absolute, and it is also affected by many factors such as design, manufacturing and operating conditions.
Overview of useful life
general life: According to the recommendations of most manufacturers and relevant standards, the general service life of the air compressor tank is 10 years.
Influencing factors: Proper maintenance and regular inspections can extend its service life, while harsh working conditions, improper operation or lack of maintenance may shorten its life.
inspection and maintenance
regular inspection: For fixed gas storage tanks or gas storage tanks exceeding the standard of simple pressure vessels, regular inspection is required. Within 5 years, the Bureau of Quality and Technical Supervision will check the pressure gauge and safety valve of the gas storage tank; more than 5 years, more comprehensive testing is required, including water pressure testing of the tank.
Exemption from inspection: simple pressure vessels (volume less than 1 cubic meters, pressure less than 10 kilograms) are exempt from inspection within the recommended service life of the manufacturer.
Inspection period: for the accessories of gas storage tank, such as safety valve and pressure gauge, the calibration period is usually one year.
Precautions
when the gas storage tank is close to the service life, it is necessary to bring the Pressure Vessel Certificate of Gas Storage Tank to the Quality and Technical Supervision Bureau, and conduct a comprehensive inspection on the gas storage tank according to the fixed pressure vessel inspection application procedure. The gas storage tank can be used only after passing the inspection. If it is unqualified, the gas storage tank shall be scrapped and a new tank shall be purchased.
In daily use, the manufacturer's recommendations and relevant regulations should be strictly followed, and the equipment should be maintained and inspected regularly to ensure its safety and reliability.
Ways to extend service life
regular drainage: After the air compressor is running, a large amount of water vapor will be generated inside the gas storage tank. Long-term accumulation will cause the gas storage tank to rust and affect its service life. Therefore, regular drainage is the key to maintaining the gas tank. It is recommended to drain at least once a day, and clean and replace the drain valve regularly.
Coating maintenance: The coating on the surface of the gas storage tank is an obstacle to prevent oxygen and water vapor in the air from entering the tank body, which reduces the corrosion rate of the inner wall of the gas storage tank. Therefore, the maintenance and maintenance of the coating is particularly important. If it is found that the surface of the gas tank is damaged or the coating is blistered, it should be repaired in time.
Inspection and replacement: After a period of use, the gas tank should be replaced in time if deformation, cracks and air leakage occur. At the same time, the exhaust system, drain valve, pressure gauge and safety valve of the gas storage tank should be inspected and maintained regularly.
In summary, the service life of the air compressor tank is generally 10 years, but it needs to be judged and maintained according to the actual situation. Through regular inspection and maintenance, its service life can be extended and its safe and reliable operation can be ensured.
The maintenance cycle of oil-free air compressors is not fixed, but is affected by many factors, including frequency of use, operating environment, machine quality, and manufacturer's specific recommendations. The following is a general maintenance cycle guide: 1. daily inspection cycle: every
How much air compressor is identified as special equipment mainly depends on its volume and pressure and other parameters. Generally speaking, air compressors with an air volume of 1000L and above and a rated working pressure of 30Mpa and above are recognized as special equipment. In addition, there are views that
Dry oil-free or water-lubricated oil-free, the answer is that there is no need to add oil. But the difference between the two is that dry oil-free is completely carried by mechanical precision, and water-lubricated oil-free is helped by water. The latter has more advantages in stability and maintenance convenience in long-term use.
Oil-free air compressors, as the name suggests, refer to air compressors that do not use oil as a lubricant during the compression process. In theory, a real oil-free air compressor should not contain any oil in its compressed air. However, in practical applications, due to the mechanical seal, ring
There are obvious differences between oil-free lubricated air compressors and oil-injected air compressors in terms of working principle and applicable scenarios: Oil-free lubricated air compressors: Working principle: This type of compressor does not need lubricating oil to lubricate its internal machinery when running Parts. It
Which kind of air compressor is durable and easy to use-take the water lubricated oil-free air compressor of Shanghai Ganklin Group as an example. In industrial production, the air compressor is the key equipment to provide air source power, and its performance and stability are directly related to the production efficiency and
Air compressors, especially the products of Shanghai Grankering Group, water-lubricated air compressors are also oil-free air compressors, which are mainly used to provide high-quality and high-efficiency compressed air in the industrial production process. Water-lubricated air compressor: This product uses water as a lubricant
Large air compressor, as an important industrial equipment, is mainly used to provide large flow and high pressure compressed air to meet the gas demand in industrial production, infrastructure construction and other fields. The following are the main uses of large air compressors: 1. main uses of industrial health
Q: Water lubricated oil-free air compressor and traditional air compressor which noise is smaller? A: Water lubricated oil-free air compressor noise is smaller. The water-lubricated oil-free air compressor adopts a silent design, and the noise during operation is relatively small, and the vibration of the machine during operation is relatively small,
The scope of use of compressed air commonly used in factories involves many aspects. The following is a clear summary of its scope of use: Power transmission: As a power source, compressed air is widely used to drive various mechanical equipment, such as pneumatic tools, pneumatic test benches, Transmission
