When closing the air pressure system and the drying system, it is usually recommended to close the air compressor first, and then close the dryer. Here are the specific reasons for this recommendation:
keep the compressed air stable: first turn off the air compressor can ensure that the compressed air supply of the system remains stable during the shutdown process. This can avoid adverse effects on equipment and processes due to pressure fluctuations.
Protect the dryer: If the dryer is turned off first, the undried air may flow to the back end of the system, which is disadvantageous in places with high requirements for compressed air quality. Stopping the air compressor first can ensure that the moisture and impurities in the system will not enter the dryer, thereby protecting the performance and life of the dryer.
Removal of residual moisture: After the air compressor is shut down, the dryer can continue to run for a period of time, which can help the system to remove residual moisture and ensure the drying effect of the system.
In summary, in order to maintain the stability of the system and protect the equipment, it is recommended to turn off the air compressor first when the machine is stopped, and then turn off the dryer.
The textile industry, a field with high requirements for air quality and stability, is ushering in the innovation of oil-free air compressor technology. The water-lubricated oil-free air compressor produced by Shanghai Granklin Group has become an ideal choice for the textile industry with its unique advantages. Textile machinery in production
The oil content standard of compressed air in factory equipment usually varies according to different industries and application fields. The following are some common compressed air oil content standards and their explanations: 1. general standards Generally speaking, the oil content standard in compressed air is 5 mg/m & su
Scroll compressor and screw compressor, the two can be described as the compressor in the world of "gentle gentleman" and "tough warrior". They have their own unique charm, let us explore their differences.
shanghai granklin group detailed air compressor products in the air compressor in the market, permanent magnet frequency conversion screw machine because of its high efficiency, energy saving characteristics and widespread concern. Among the many air compressor manufacturers, Shanghai Granklin Group
The frequency conversion screw machine is a kind of equipment that can adjust the operating frequency and speed. It combines the frequency conversion technology and the working principle of the screw machine. The following is a detailed explanation of the main functions and uses of the frequency conversion screw machine: Working principle: Screw machine part: Screw
Oil-free air compressors are designed to avoid the use of oil in the compression process, but in practice it may be found that the compressed gas still contains oil. This is mainly caused by the following reasons: the oil contained in the air itself: naturally occurring in the air
Each gas-consuming equipment (such as pneumatic tools, spraying equipment, packaging machinery, etc.) will be marked with a rated gas consumption (in cubic meters per minute or liters per minute). Add up the gas consumption of all equipment running at the same time to obtain the theoretical total gas consumption.
Air compressor from the early piston air compressor, in recent years, constantly updated technology, in response to the industrial upgrading of enterprises, granklin group air compressor has achieved water lubrication oil-free industrial quality. At present, the pharmaceutical industry, the food industry on the gas source requirements are very high, industrial upgrading has become a must. Eliminate the old-fashioned oil-free air compressor and replace it with a new oil-free air compressor. In particular, Granklin energy-saving variable frequency air compressor can be very good, for enterprises to save energy, reduce power consumption. In response to the national call, energy conservation is a top priority and can also reduce business expenses.
View detailsThe air quality standard of the oil-free screw air compressor outlet is mainly concerned with the oil content in the compressed air. Generally, in the outlet air quality standard of oil-free screw air compressor, the oil content is controlled at a very low level, generally at 0.01ppm (one part per million) or
When selecting an air compressor according to the air consumption of the equipment, the following key factors need to be considered: Determine the air consumption: First, understand the rated air consumption of all gas-using equipment and accumulate them to obtain the total air consumption of the entire process or system. Consider the equipment
