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.
If the air compressor you use belongs to the pressure vessel in the equipment specified in the supplementary provisions of the national "special equipment safety supervision regulations", your operator should consult the operator examination organization 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 ℃.
In many aspects of modern industrial production, screw air compressor as the key equipment of gas compression and power transmission, its performance stability and technical advancement play an important role in ensuring production efficiency and product quality. In many air compressor brands
The first maintenance time of the new air compressor may vary according to different situations and manufacturer recommendations. However, in general, the new air compressor should be maintained for the first time after 500 hours of operation. This maintenance is relatively simple, mainly to replace the oil, oil filter and air
Analysis of Permanent Magnet Air Compressor Technology and Interpretation of Granklin Air Compressor Advantages In the field of air compression equipment, permanent magnet air compressor, with its high efficiency and stability, like the "engine of energy-saving cars", has become the preferred selection of industrial users. The following from the technical principles, city
In industrial production, the quality of compressed air directly affects the final quality of the product, in which the water content of the air is one of the important indicators to measure the quality of compressed air. Shanghai granklin group production of water-lubricated screw air compressor, combined with efficient cold dryer system
Professional instructions on the output pressure of air compressors in large factories The output pressure of air compressors in large factories shall be comprehensively determined according to the production process, equipment characteristics and safety specifications, and there is no globally unified fixed value. Now from the technical standards, industry practice and optimization direction to provide
When the air compressor output with water, usually refers to the compressed air contains too much moisture, which may affect the use effect and may cause equipment damage. For the water-lubricated oil-free variable frequency screw air compressor of Shanghai Granklin Group, although it is adopted.
Both power frequency compressors and inverter compressors are equipment used to compress air, and there are significant differences in many aspects. The following is a detailed comparison of these two compressors: 1. drive mode and working principle Power frequency compressor: Drive mode: use power frequency motor
The selection of air compressors should be determined according to the specific needs and usage scenarios of the equipment. The capacity or power range of air compressors usually equipped with different equipment is quite different. The following is a detailed analysis of the selection of general equipment air compressor: 1. air compressor type and applicable scene piston
There are significant differences between oil-free air compressor and oil-free air compressor in terms of working principle, performance and application field. Working principle: The oil piston air compressor will be connected with lubricating oil during the compression process to help seal, cool and lubricate, thereby improving the machine's
There are several main differences between oil-free compressors and oil-based compressors: Lubrication: Oil-free compressors do not require lubricating oil to lubricate their moving parts during operation. It uses specially designed seals and bearings to ensure oil-free operation. There are
