The pressure of the general air compressor varies according to the use requirements and the environment. For the pressure range of ordinary air compressors, the rated working pressure can usually reach 0.7-0.8Mpa, but in actual use, the discharge pressure of most compressors is about 0.6Mpa. Some special high-pressure air compressors, such as high-pressure air compressors, exhaust pressure can reach up to 5.0Mpa. However, the discharge pressure indicated on the compressor nameplate is the rated working pressure of the compressor, that is, the highest pressure that allows the compressor to run continuously. When the actual discharge pressure of the compressor is higher than this value, it should be forced to unload, otherwise the safety valve will automatically discharge.
In addition, for screw air compressors, the exhaust pressure during normal operation is 0.7-0.8Mpa, while some high-pressure screw air compressors can reach a working pressure of about 1.0Mpa, and even some screw machine exhaust pressure can reach 1.4-1.6Mpa. However, long-term high-pressure operation will accelerate the wear of the screw and bearing, which has a great impact on the life of the machine.
When choosing an air compressor, the appropriate pressure range should be determined according to actual needs, and the machine should be prevented from running under high pressure for a long time to extend the service life of the equipment. At the same time, in order to maintain the normal operation of the air compressor, regular maintenance and maintenance are required, including replacing the filter, checking the oil level, and cleaning the radiator.
In general, the pressure of the air compressor depends on its type and use environment. In general industrial applications, the pressure range of the air compressor is between 0.6-1.6Mpa.
In the medical compressed air system, the choice of air compressor is very important, which is directly related to the stable operation of medical equipment and the life safety of patients. As one of the leading air compressor manufacturers in China, Shanghai Granklin Group's water-lubricated screw air compressor products are in the medical market.
When discussing whether the air compressor is refueling well, we must first clarify two different types of air compressors: oil air compressors and oil-free air compressors, each of which has its own advantages and disadvantages. The advantages of oil air compressor: good lubrication performance: the use of lubricating oil can effectively reduce mechanical wear,
The design service life of a pressure vessel is an important safety indicator, which indicates the period of safe use of the vessel under normal operating conditions. The following is how to view and understand the design service life of pressure vessels: consult relevant standards and
The compressor does not belong to, and the air storage tank matched with the air compressor belongs. 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 you are
There is a close relationship between the air production and the pressure of the air compressor. The following is a detailed explanation of this relationship: Basic concept: Air production: usually refers to the volume of compressed air produced by the air compressor per unit time. Pressure: indicates air compressor
The air compressed by the air compressor usually contains moisture, which may cause damage to the equipment using the air. Therefore, gas water removal is a very important part of the air compressor system. The following are some air compressor gas water removal methods: cooling method:
Answer: The air tank is a drain valve, the amount of water vapor or more can use the dryer (freeze dryer, adsorption dryer), in the collocation of post-processing with precision filters, you can effectively remove the water in the compressed air.
1. The working principle is different. The working principle of the scroll air compressor The main components of the scroll compressor are two involute scroll coils with the same shape but the angular phase position is relatively staggered by 180 °. One is a fixed coil, and The other is carried by an eccentric shaft
The starting sequence of the air compressor and the cold dryer can be slightly different according to different operating habits or equipment design, but the usually recommended starting sequence is to open the air compressor first, and then open the cold dryer. The specific operation steps are as follows: First, turn on the total air switch, and then
According to international standards and industry norms, the oil content of compressed air in contact with food shall be strictly controlled by grading. The specific standards are as follows: 1. direct contact with food scenes (such as ingredients, fermentation and stirring) International standard: ISO 8573-1:2010 Class 1: Oil content ≤ 0.0
