Compressor dynamic equipment does not belong to special equipment, but 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 pipe diameter are greater than or equal to 25mm, it belongs to special equipment.
The oil and gas separator on the air compressor is as follows: volume: 0.063m & sup3;, design pressure: 1.57MPa, pressure test pressure: 1.97MPa, working medium: air and oil, temperature: 120 ℃.
Section 7.1.11 of the TSG21-2016 "Safety and Technical Supervision Regulations for Stationary Pressure Vessels" makes some special provisions for simple pressure vessels: simple pressure vessels do not need to be registered for use and do not need to be inspected regularly within the design period, but there is no mention of installation qualification and whether construction notification is required.
Provisions of Articles 2 and 3 of Supervision Regulation on Safety Technology of Stationary Pressure Vessels
for the air compressor system, it can be briefly considered as "the design pressure is less than or equal to 1.6MPa, the volume is less than or equal to 1000L, the product of working pressure and container is greater than or equal to 2.5MPa.L, and is less than or equal to 1000MPa.L".
That is to say, in the compressed air system for general use, if the air storage tank is less than 1 cubic meter or 10kg, or if the pressure is higher than 10kg and lower than 16kg, the capacity is less than 1 cubic meter and the product of pressure and volume (unit L) is less than 1000, it is a simple pressure vessel.
The oil and gas barrel and cooler cylinder in the air compressor body; the filter tank body; the dryer cylinder body, etc. basically will not exceed the scope of "simple pressure vessel. This is mainly because the simple pressure vessel is easy to install and use (you don't need to report for installation or apply for a registration certificate).
The moisture content in the air is not a fixed value. It is affected by many factors such as temperature, pressure, humidity, etc. The following is a detailed description from different angles: The moisture content in the standard state is in the standard state (temperature is 0 ℃, pressure is 1 Under standard atmospheric pressure), dry
The water content of air compressor system is a complex and changeable problem, which is affected by many factors, including air humidity, compressor type, operating conditions and subsequent processing equipment. The following is a detailed analysis of the water content of the air compressor system: 1. air compressor system
There are significant differences between oil-injected compressed air (take oil-injected screw air compressor as an example) and oil-free compressed air in many aspects, including lubrication mode, use environment, structural characteristics, energy efficiency and compressed air quality. The following is a detailed description of these differences.
Air compressors, cold dryers and dryers play an important role in the compressed air system, and they are closely related and complement each other. The following is a detailed analysis of the relationship between the three: 1. equipment function air compressor: definition: air compressor is a kind
There are several key differences between the oil-free scroll air compressor and the oil-free screw air compressor: Working principle: The oil-free scroll air compressor rotates around the center of the base circle of the fixed scroll through the movable scroll and meshes with each other to achieve suction., Compression and exhaust process.
There are many reasons behind the configuration of multiple air compressors in the factory, which together ensure the efficiency and stability of the production process. First of all, the production process of a factory often involves multiple links and departments, and the demand for compressed air in each link may vary.
The food processing industry has strict grade requirements for the compressed air used to ensure the quality and safety of food. The following are the main grade requirements for compressed air in the food processing industry: 1. main indicators require oil content: compressed air is required to contain almost no
The replacement cycle of the lubricating oil of the new screw air compressor is affected by the type of lubricating oil, the working environment and the frequency of use. The following is a detailed guide: 1. the first oil change cycle, the running-in period of the new machine: it is recommended to replace the first lubricating oil after 500 hours of operation to remove the initial oil.
As a general power source, compressed air is widely used in a large number of industries. The following is a summary of some major industries and their compressed air applications: 1. Textile, printing and dyeing, and clothing industries In the textile, printing and dyeing, and clothing industries, compressed air is mainly used
There is a close relationship between air compressor gas production (usually we more often discuss the exhaust volume) and gas transmission pipe diameter, which is affected by many factors. The following is a detailed analysis of this relationship: the definition of 1. air compressor displacement air compressor displacement refers
