Air compressor is not special equipment. However, as long as the working pressure of the gas storage tank and the connected pipeline is greater than or equal to 0.1Mpa, the volume and the pipe diameter are greater than or equal to 25mm, it belongs to special equipment.
Special equipment refers to boilers, pressure vessels, pressure pipes, elevators, lifting appliances, passenger ropeways, large amusement facilities and special motor vehicles in the field (factory) that involve life safety and high risk. Among them, boilers, pressure vessels (including gas cylinders) and pressure pipes are special pressure-bearing equipment; elevators, hoisting machinery, passenger ropeways and large amusement facilities are electromechanical special equipment.
the role of air compressor:
1. Air compressors for gas transportation are also used for gas pipeline transportation and bottling, such as remote gas and natural gas transportation, chlorine and carbon dioxide bottling, etc.
2. Used for gas synthesis and polymerization. In the chemical industry, some gases are synthesized and polymerized after the pressure is increased by the compressor, such as helium synthesis from hydrogen and hydrogen, methanol synthesis from hydrogen and carbon dioxide, urea synthesis from carbon dioxide and ammonia, etc., and polyethylene production under high pressure.
3. The gas used for refrigeration and gas separation is compressed, cooled, expanded and liquefied by an air compressor. It is used for artificial refrigeration. This type of compressor is usually called an ice maker or an ice machine. If the liquefied gas is a mixed gas, each group can be separated separately in the separation device to obtain various gases with qualified purity, such as the separation of petroleum cracking gas. First, it is compressed, and then each component is separated separately at different temperatures.
4, can be used as aerodynamic air after compression can be used as power, mechanical and pneumatic tools, as well as control instruments and automation devices, instrument control and automation devices, such as machining center tool replacement.
The pressure of air compression pipeline in clean area workshop should be determined comprehensively according to industry specifications, equipment requirements and system efficiency. The following is specific guidance: 1. conventional pressure range Pharmaceutical/electronic industry: The pressure of compressed air pipeline in clean area is usually 5-7 bar (gauge pressure). Food
The two air compressors themselves cannot realize the concept of "unlimited endurance", because any mechanical equipment has its operating life and the characteristics of maintenance. But if the ability to work from a continuous point of view, two air compressors can be reasonable
There is a close relationship between the exhaust pressure and energy consumption of screw air compressor. The following is a detailed analysis of this relationship: 1. basic concept Exhaust pressure: refers to the highest pressure of the air compressor discharge gas, also known as the air compressor working pressure. Common working pressure
The procurement characteristics of the semiconductor equipment industry are mainly reflected in the following aspects: supply chain complexity: the supply chain of the semiconductor equipment industry involves multiple links, including raw materials, parts, equipment and technology. There are a large number of suppliers, and each supplier is in the regulations.
Oil-free air compressor selection, how to choose a good oil-free air compressor brand, as a production machine, from procurement selection to production operation, all need a strong manufacturer to provide solutions. Granklin Group, a domestic air compressor manufacturer, has been operating for many years and has a number of air compressor patents.
Regarding the comparison of the technical characteristics of screw and scroll air compressors In the field of compressed air equipment, screw and scroll compressors have different application characteristics due to structural differences. The specific differences can be summarized as follows: Differences in working principles Screw compressors: Through Yin and Yang Turn
Circulating water scaling will significantly increase the energy consumption of air compressor, mainly by reducing heat exchange efficiency, increasing system resistance, causing equipment failure and other ways to achieve. Granklin water-lubricated screw air compressors reduce some of the scaling risk through oil-free design, but still need to pay attention to follow.
The maximum oil content of oil-free air compressor should be specified according to international standards and industry classification. The core conclusions are as follows: 1. international standards: Class 0 oil-free standards (oil content ≤ 0.01 mg/m & sup3;) According to international standard ISO 8573-1:2001 and equivalent standard in China
Poor lubricating oil quality will have a negative impact on air compressors in many aspects, involving equipment performance, service life, operational stability, and maintenance costs. The following is the specific impact and analysis: 1. lubrication performance decline, accelerated mechanical wear lubrication insufficient guide.
The price of low pressure screw air compressor varies with brand, model, power, configuration and other factors. As an air compressor manufacturer, Shanghai Grankering Group provides various types of screw air compressors, including low-pressure screw air compressors. However, the specific price needs to be based on the customer.
