Air compressor general classification has the following several categories:
1. According to the gas transmission volume, to put it bluntly, the gas transmission volume refers to the volume calculated from the gas discharged per minute during the operation of the air compressor to the suction situation. The small and medium-sized exhaust volume is below 10 cubic meters/minute, the small and medium-sized exhaust volume is 10~100 cubic meters/minute, and the large and medium-sized exhaust volume is above 100 cubic meters/minute.
Domestic models have 0.3, 0.6, 0.9, 1.6, 3, 6, 9, 10, 12, 20, 40, 60, 100 per minute of displacement. Among them, small servers and small and medium-sized enterprises account for a very large proportion. Extras above 100 are not common and are limited to specifications and net weight. Piston air compressors with displacement above 100 are unscientific.
2. According to the structure, it is divided into tube type, piston type and membrane type.
Among them, the screw compressor in the piston type and the tube type and the sliding built-in type are more common. China's piston accounted for 95% of production, while overseas screw compressors accounted for more than 90%, these three air compressors have their advantages and disadvantages.
Extruder screw air compressor because of the motor rotor type line complex, high manufacturing cost, but small size, light weight, small parts is its advantage. Under the condition of the same displacement, the screw compressor air compressor is much more expensive than the piston type, and its maintenance must have professional knowledge and work experience.
3. According to the cylinder axis and relative position, it is divided into vertical type, vertical type and viewing angle type, and the viewing angle type is divided into V type, W type, L type, etc.
Generally speaking, because piston air compressors are reciprocating equipment, they all have certain vibrations, and the viewing angle type can well balance their moment of inertia. Therefore, most large, medium and small piston air compressors are basically made of viewing angle type. Only the air compressors for vehicles and ships are limited by the land occupation. They are the founding type. The vertical type is the air compressor of bellows type. They are the products of industrial production generation. They have no advantages and are basically not manufactured now.
4, according to the refrigeration method:
because the air compressor can expand the temperature rise when the steam is reduced, it must be refrigerated in many ways. Generally, there must be a positive middle cooling tower for each level of reduction, so it is divided into water cooler and air cooler according to the cooling tower method. The water cooler is cooled by an open-loop system of drinking water; the air cooler is cooled by a cooling fan.
5, according to the transmission device is not the same classification:
there are motor drive method, diesel engine drive method. Large and medium-sized pneumatic type is equipped with power distribution box, diesel engine driver type is started by battery, and both air compressors have direct connection and side connection (I. e. synchronous belt drive).
6, according to the lubrication method:
the oil-free type, and the automobile engine oil-lubricating type, the latter is divided into splash type and mandatory type (that is, the oil-lubricating type provided by the gasoline pump and the fuel pump).
With the accelerating process of industrialization, the consumption rate of energy resources is also increasing year by year. The shortage of resources has led more and more people to pay attention to environmental protection and energy conservation. Electric cars, ethanol gasoline and so on are energy-saving products. In this strong energy-saving environment, air compressor as an important part of production and life has attracted much attention. Shanghai Granklin Group, in response to social needs, developed a series of energy-saving air compressor, widely praised by users.
View detailsThe reasons why the air compressor does not pump air are as follows: it has good environmental adaptability, and the operating cost is economical and the energy-saving effect is excellent. 1. The loose pressure valve of the air compressor is stuck, and the valve plate is deformed or broken. 2. Excessive carbon deposits at the inlet and exhaust ports. 3. No intake valve
Screw air compressor operating procedures: 1. operators must be familiar with the structure, performance, working principle, operating procedures and precautions of the air compressor. 2. operators must undergo technical training and safety training and pass the examination.
The post-processing equipment of the air compressor, the cold dryer and the suction dryer are one word different. Although the functions are similar, the use characteristics and the demand environment are very different. This time we will analyze the characteristics of the cold dryer, the difference between the cold dryer and the suction dryer, and how to make the correct choice.
Choose Shanghai Granklin Group to purchase air compressors, whether it is price or service, do not lose imported screw air compressors. As for the price of an air compressor, the things involved are also in all aspects. Price is an important reference standard, but it is not the only weighing standard. We will definitely get good results under a telephone consultation.
View detailsIn the field of food production, the quality of compressed air is directly related to food safety and product quality. In view of the problem of "whether the air compressor in the food factory can use the micro-oil air compressor", it is necessary to advance from the aspects of food safety risk, regulatory requirements and industry practice.
Basically, according to each air compressor factory has a standard for its own air compressor, it is best to look at the instructions! Some manufacturers also have 2000 hours of oil and 4000 hours of oil. Some are calculated from the sale to the customer, the initial insurance time and the later period.
When the laboratory uses compressed air, it needs high-quality oil-free air. The "water-lubricated oil-free air compressor" produced by "Shanghai Grankering Group" can provide 100% oil-free "oil-free compressed air" for high-precision tests ". In the laboratory ventilation equipment we can refer to the following:
There is a complete set of procedures for the installation of screw air compressors. Although the standards of various manufacturers are different, the general steps are similar. On the basis of summarizing the installation and debugging experience of many air compressors, the author now writes down the general steps and matters needing attention in an article to provide reference for peers to smoothly carry out the installation and debugging of air compressors.
Types of oil-free air compressors are divided according to whether the compressed air contains oil or not, corresponding to oil-free air compressors or micro-oil air compressors. Oil-free air compressors are distinguished according to different compression forms or different host structures. Several common oil-free air compressors are: oil-free
