During the operation of the screw air compressor, it is sometimes found that the air compressor has a continuous low pressure.
Today, we will take you to understand the cause of low pressure in air compressors and how to solve this problem in future applications.
Whether the gas consumption increases.
If other equipment is added to the gas end, the output of the originally purchased air compressor may not meet the current gas consumption requirements, and another air compressor needs to be considered.
Whether the pipeline leaks.
Some pipelines have some small cracks due to long use time or do not pay attention to daily maintenance, which leads to gas leakage and the pressure cannot rise. The treatment method is to find the source of the leakage and then repair it. When installing an air compressor, it is best to buy good quality pipes.
Working pressure setting too low.
In this case, the system parameters are usually adjusted after the working conditions change or the system is adjusted or overhauled, otherwise the working pressure is not easy to operate by mistake after setting.
It is not recommended that users set compressor parameters at will, cooperate with equipment suppliers and users, comprehensively consider the working conditions and equipment operating characteristics, and set reasonable values.
Whether the air filter core is blocked.
The air filter element is used to filter dust and impurities in the air, but if the filter element is not cleaned for a long time, it is easy to block. Most of the time, the compressor exhaust volume drops, there is no big problem, is the customer neglect maintenance. If the working environment is not ideal, the compressor air filter is easily blocked. Light can use compressed gas dust removal; serious blockage, need to replace the new air filter.
Whether all intake valves are open.
Remove the intake hose, open the compressor, and observe whether the opening of the intake valve is normal.
Generally speaking, the theoretical design life of the intake valve is 100000 times. Due to the different brand batches and quality of each manufacturer, the failure of the intake valve may cause the unit's exhaust volume to drop.
If the intake valve is not fully opened during the operation of the unit, it can be judged that the reason for the decrease in exhaust volume is that the intake valve is faulty and should be removed, repaired or replaced.
Whether the machine head is aging.
The head is the central part of the air compressor, and the head is the power source of the entire equipment. If nothing else is wrong, then the problem is probably here. You can contact the manufacturer for testing, repair or replacement.
People often ask me, is there really an oil-free and water-free air compressor? It is impossible to have an oil-free and water-free air compressor, because the air contains moisture, and the amount of compressed air is large in the air storage tank. Does the gas contain oil and gas?
Water lubricated oil-free screw air compressor is also called water jet screw air compressor, that is, screw air compressor, there are also single screw air compressor, which means that the rotor chamber sucks in air at the same time, but also sucks in water (plays the role of lubricating the rotor and sealing)
Shanghai Granklin Group is engaged in the production of "oil-free air compressor", integrating R & D, production, sales and after-sales. As a member of domestic air compressors, the brand of "Granklin air compressor" has gradually occupied a place in the domestic "oil-free air compressor" market after years of operation and development.
Why does the compressed gas of the screw air compressor produce water? How can we efficiently remove the moisture in the compressed gas of the screw air compressor? Is there really an oil-free and water-free screw air compressor? People in the workshop see this question. As a member of the air compressor industry, it is more reasonable for us to answer this question.
View detailsWhat are the daily contents of air compressor maintenance? What are the advantages of screw air compressor compared with piston air compressor? How does air compressor work? Air compressor is also called air compressor, which is a kind of equipment used to provide kinetic energy after compressing air. It is made of motor or wood
1. The air compressor shall be operated by designated trained and qualified students, and shall be used only after being guided and inspected by the instructor on the spot. 2. When using, pay attention to check whether the instruments, valves and electrical facilities are normal. sufficient lubricating oil, and
Application industries of water-lubricated air compressor produced by Shanghai Granklin Group: university laboratory, chromatographic analysis, medical pharmacy, dentistry, food processing, construction engineering, chemical industry, machinery, environmental protection, meteorology, hydropower, spraying, sandblasting, PET bottle blowing, leak detection, metallurgy, water treatment, printing, shipping, textile, petrochemical, electronics
View detailsScrew compressor is a kind of power equipment widely used in the field of petrochemical and industrial production, and its safe and reliable operation is of great significance to ensure production, so it is necessary to focus on it. A screw compressor is arranged in parallel in the cylinder of the main engine.
Air compressor faults and treatment methods The high temperature rise of the outlet temperature or exhaust temperature of the air compressor head is a common fault in the operation of the screw air compressor. The screw air compressor often runs at high temperature, which will seriously affect the displacement and operation of the machine.
Air compressors can be divided into two types according to different lubrication methods. One is oil-free air compressors and the other is oil-free air compressors. The latter uses lubricating oil to lubricate the parts to reduce the wear between the parts. And oil-free air compressor operation process without lubricating oil to participate in
