Whether air compressors and air storage tanks are special equipment depends on their specific specifications and working pressure.
For air compressors, in general, it itself is not directly regarded as special equipment. However, if the pressure vessels such as air tanks equipped with air compressors meet the definition of special equipment, then these pressure vessels need to be managed according to special equipment.
The gas tank may belong to special equipment, which mainly depends on its working pressure and volume. In China, according to the Special Equipment Safety Law and related regulations, special equipment usually refers to equipment that involves life safety and is more dangerous, including boilers, pressure vessels (including gas cylinders), pressure pipes, elevators, lifting machinery, Passenger ropeways, large amusement facilities and special motor vehicles in the field (factory). For a gas storage tank, if its design pressure is greater than or equal to 0.1MPa, its inner diameter is greater than or equal to 150mm, its volume is greater than or equal to 30L, or its inner diameter is greater than or equal to 150mm, and the product of working pressure and volume is greater than or equal to 2.5MPa · L, then it is regarded as special equipment and needs to comply with relevant safety technical specifications.
Therefore, it is necessary to judge whether the air compressor and the air storage tank belong to special equipment according to the specific situation. If the gas tank meets the definition of special equipment, it is necessary to carry out registration, regular inspection and use management in accordance with relevant regulations.
Good or bad depends on the occasion of use and the actual working conditions. In some cases, such as food, medicine, precision instruments and other industries, it is necessary to use a full oil-free air compressor. But the oil-free air compressor is much more expensive and the maintenance cost is higher. Such
The presence or absence of oil in an air compressor generally refers to the amount of oil content in the gas discharged from the exhaust port of the air compressor. Oil containing machines generally have a higher oil content, while oil-free machines have an oil content of 0.01ppm. Therefore, this oil content is used to distinguish between oil containing and oil-free air compressors Choosing the appropriate air compressor based on the demand for gas sources in different industries can save operational costs for enterprises
View detailsScroll type oil-free model: through high-precision processing and sealing design, completely avoid oil pollution, suitable for high air cleanliness requirements of the scene. Single screw type oil-free model: the use of water instead of oil for lubrication and cooling, the need to regularly replace the circulating water and clean up the scale, maintenance complexity is higher than the scroll type, but can provide oil-free compressed air.
Frequency conversion oil-free air compressor for enterprises, especially with a very large amount of gas enterprises, can save a lot of energy consumption. Reducing the energy consumption of air compressor can save a lot of money for production cost. Oil-free air compressor is a mechanical product, it is best to choose high reliability when buying. Mechanical products are prone to wear after a long period of work. It is best to choose a low speed when using them. This is a small way to extend the service life of oil-free air compressors. In addition, when buying, you should choose a manufacturer with long warranty time and good after-sales service.
View detailsWhen discussing whether the air compressor system must include a suction dryer (I. e. adsorption dryer), we need to clarify the main components of the air compressor system and its functions. The air compressor system mainly consists of the air compressor body, the cooling system, the filtration system, the gas storage tank and the possible
When selecting an air compressor according to the air consumption of the equipment, the following key factors need to be considered: Determine the air consumption: First, understand the rated air consumption of all gas-using equipment and accumulate them to obtain the total air consumption of the entire process or system. Consider the equipment
The types of enterprises that need air compressors and the application scenarios of water-lubricated air compressors 1. the core types of enterprises that need air compressors manufacturing automobile manufacturing: used to drive pneumatic tools (such as wrenches and spray guns), automation equipment and tire inflation. Mechanical
In the pursuit of high efficiency, environmental protection, energy-saving modern industrial field, oil-free water lubrication air compressor with its unique advantages gradually recognized by the market. Among them, the water-lubricated screw air compressor products produced by Shanghai Granklin Group have become the most important products for their excellent performance and quality.
In industrial production, the air compressor is an important air source equipment, and the compressed air produced by it often contains a certain amount of moisture, which is unfavorable for many precision processes and equipment. Aiming at the problem of water in air compressor gas, Shanghai Granklin Group produces water moistening
Air compressor has been working does not stop, may be caused by a variety of reasons. The following are some possible reasons and corresponding solutions: Possible reasons and solutions Causes of pipeline leakage: There is a leakage problem in the compressed air pipeline, and the air compressor will be unable to reach it.
