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.
An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston type, rotating blade or rotating screw. Centrifugal compressors are very large applications.
If the air compressor used belongs to the pressure vessel in the equipment specified in the supplementary provisions of the national "special equipment safety supervision regulations", the operator should consult the operator examination institution with the special equipment safety supervision department of the local bureau of quality and technical supervision, and then obtain the qualification certificate.
The pressure vessel stipulated in the Regulations refers to the closed equipment containing gas or liquid and bearing a certain pressure, and its scope is specified as the fixed vessel and mobile vessel for gas, liquefied gas and liquid with the maximum working pressure greater than or equal to 0.1MPa (gauge pressure) and the product of pressure and volume greater than or equal to 2.5MPa · L; gas cylinders and oxygen chambers with nominal working pressure greater than or equal to 0.2MPa (gauge pressure) and the product of pressure and volume greater than or equal to 1.0MPa · L, liquefied gas and liquid with standard boiling point equal to or lower than 60 ℃.
1. Add the following net cover at the air compressor room and air inlet of the air compressor. 2. Regularly purge the air inlet of the air compressor, filter cotton, cooler and cooling fan cover of the motor. 3. Regularly observe the operating temperature of the air compressor. In case of high temperature, check the machine in time
The requirements for the dew point of compressed air in battery manufacturing are usually very strict, generally below -40 ℃, and some key processes even require -50 ℃ to -60 ℃. This requirement stems from the extremely high standards of air quality in battery production-any trace of moisture may cause moisture in battery materials and deterioration of electrolyte, which in turn leads to battery performance degradation, shortened life, and even safety hazards.
Oil-free compressed air has a wide range of uses, which can be summarized as follows: Medical and health field: In the medical and health field, oil-free compressed air is widely used in various equipment and instruments, such as ventilators, air pressure treatment equipment, etc. Because of these
In the pharmaceutical industry, compressed air systems play a vital role. It is widely used in many aspects of drug production and has become a key factor to ensure drug quality and production efficiency. The following are the main functions of the compressed air system of the pharmaceutical factory: 1. power source pharmaceutical equipment
Based on publicly available information and the technical characteristics of Granklin Group's water-lubricated air compressors, the range of gas production for the 75kW model is as follows: Core Conclusions Granklin 75kW water lubricated screw air compressor rated gas production of about 9-12.6 cubic meters/minute, the specific value
The traditional air compressor drainage is to discharge waste water, which is as clean as possible but not serious. Water lubricated air compressor drainage is the discharge of excess condensed water, circulating water to stay. Either way, stopping the front row once is the most basic operating habit.
The oil-free level standard of air compressor mainly refers to the international standard ISO 8573-1, which classifies the oil content in compressed air in detail. In the definition of oil-free level, the main concern is that the oil content in compressed air must be very low to meet the requirements of air quality.
The quality of permanent magnet screw air compressor is mainly reflected in the following aspects: high efficiency and energy saving: due to the use of permanent magnet motor and advanced screw technology, this type of air compressor can efficiently convert electric energy during operation and reduce energy waste. At the same time, its special screw set
The frequency of replacement of precision filter elements depends on a number of factors, including filter type, operating environment and quality. Generally speaking, under normal conditions, it is recommended to check and replace the filter element every 3 to 6 months. However, if the water quality is poor or the air pollution is severe
According to many years of experience, in order to screw air compressor efficient and stable operation, must do its daily maintenance work. On the maintenance of the unit to "two hot". First of all, enterprises should be hot, attach great importance to the timeliness of maintenance, and see that maintenance is equipment.
