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.
The screw air compressor is an oil-injected single-stage twin-screw compressor. It adopts high-efficiency pulley transmission to drive the main engine to rotate for air compression. The compressed air in the main engine is cooled by oil injection. The air and oil mixed gas discharged from the main engine are coarse and fine. Two separate
If you determine the size and type of compressor, but there is a problem is the choice of oil lubrication or oil-free air compressor. In order not to make the answer too complicated, your choice should be based on the application of compressed air. Do I need an oil-free compressor?
In the air compressor industry, Shanghai granklin group is a positive response, we produce water lubricated single screw air compressor is in line with environmental protection requirements, compressed gas does not contain a drop of lubricating oil. In the market reflected well, in the medical, pharmaceutical, food, chemical and other industries have made excellent results.
View detailsI believe everyone has experienced the air compressor host or motor overload, maybe it is a small problem for you, maybe you are troubled by this fault. The reasons for the failure are: 1. The voltage is too low: the rated working voltage of the general compressor is 380V, and the upper and lower levels are allowed to float at about 5%.
The rear end of the air compressor is generally equipped with a gas storage tank. There is a drain valve at the bottom of the gas storage tank. Just open the drain valve every morning before starting the machine. 1. The air compressor will have a drain valve at the lowest part of the cooler; 2. After the air compressor is exhausted, a cold dryer or dry
The water lubricated oil-free air compressor uses pure water lubrication that meets the drinking water standard, and the entire compression process is completely free of oil. Thus, 100% oil-free clean compressed air is provided. Product features: 1. High efficiency, high reliability, 100% pure oil-free
The oil-free screw air compressor in the factory usually needs to run all day and consume a lot of electricity. Advanced frequency conversion technology not only helps to save energy, but also makes the operation of the air compressor simple and stable. So in the choice of oil-free screw air compressor inverter should pay attention to what?
View detailsChoose air compressor according to the needs of different industries and working conditions, there are corresponding standards. Then how to choose a suitable oil-free air compressor? 1. First figure out what is an oil-free air compressor and why should it be used? The oil-free air compressor has been running
Granklin medical air compressor, water lubrication system is perfect for medical treatment. If the hospital wants the patients to get the compressed air with reliable quality, stable flow rate and pressure, and medical grade quality, it needs a set of centralized air supply system which can meet the specific needs of modern hospitals. Whether used in routine care, intensive care, emergency rooms or operating rooms: in all departments of the hospital, patients rely on reliable mechanical ventilation, and medical equipment requires reliable equipment to be powered by gas.
What are the advantages of a long-tested market-tested "water-lubricated air compressor"? It is necessary to explain in detail that water-lubricated air compressor, products such as "air compressor head" use water instead of traditional lubricating oil to lubricate the air compressor head.
