Insufficient air supply to the air compressor may be caused by a variety of reasons. The following are some possible reasons:
maintenance is not timely: when the operating environment of the unit is not ideal, check whether the air filter and oil filter are blocked. If the air filter and oil filter are clogged and the exhaust volume drops, you only need to replace the three filters and one oil.
The operating pressure of the unit is set too low: adjust the pressure as needed, and some companies reduce the pressure in order to save energy, so that the workshop pressure cannot rise.
Frequent unloading causes the air pressure to fail to rise: the air compressor is loaded after starting. If the pressure cannot continue to appear false loading, it is a machine loading failure. Check the loading and unloading solenoid valve or small piston, check whether there is any power supply problem or blockage, and handle the loading and unloading failure in time.
The intake valve cannot be opened or cannot be fully opened: The failure of the intake valve will cause the unit's exhaust volume to drop, so the intake valve needs to be checked regularly.
Motor failure: due to local failure of the motor coil, such as bearing wear. The motor shaft wear causes the motor speed to be lower than the rated speed and the compressor displacement to decrease.
Loose motor belt: resulting in a decrease in transmission efficiency.
There is a leak in the pipe network: a leak in the pipe network will cause the pressure to drop, and the leak point needs to be checked and repaired.
Excessive deposits in the oil-water separator, pipeline or compressed air filter cause blockage: it needs to be cleaned and replaced regularly.
The exhaust valve of the air compressor is not tightly sealed, the spring is too soft and broken, the cylinder head bolts of the air compressor are loose, the sand holes and the cylinder head gasket are damaged and the air leaks: the damaged parts need to be checked and replaced.
Air compressor cylinder liner and piston ring wear serious, resulting in air leakage: need to replace the wear parts.
Selection problem: Many users do not know the specific gas consumption of their own production at the beginning, so they select the type approximately. At this time, the exhaust pressure cannot rise and is lower than the rated exhaust pressure, which cannot meet the normal gas consumption of the factory. At this time, new units can be added to make the displacement of the air compressor more than 10-20% of the gas consumption the most scientific.
It should be noted that the above are only some possible reasons, and the actual situation may vary due to factors such as equipment model and use environment. When troubleshooting problems, it is recommended to proceed step by step from simple to complex. If the problem cannot be solved, it is recommended to contact professional maintenance personnel for inspection and maintenance.
To ensure that the air compressor does not carry water, the key is to effectively control the moisture content in the compressed air. The following are some recommended measures to achieve this goal: After cooler: Installing an efficient after cooler can significantly reduce the temperature of compressed air, from
In the field of air compressors, PPM(Parts Per Million) is usually not a parameter used to directly describe the performance of air compressors. However, in the quality detection of compressed air, PPM is an important indicator, it is the representation of volume concentration, used to quantify the compressed air
Answer: A few kilograms of air compressor value "bar",1bar is equal to 0.1MPa, the most circulating on the market is 8kg pressure screw air compressor.
Q: Water-lubricated oil-free air compressor and traditional air compressor which is more durable? A: Water-lubricated oil-free air compressor is more durable than traditional air compressor. The service life of the water-lubricated oil-free air compressor is longer, because the water lubrication technology can effectively reduce the operation of the machine
The main methods of removing moisture from air compressors are as follows: Cold and dry water removal: Principle: Use compressed air to enter the cooler to reduce the surface temperature to below the dew point, and the water vapor condenses into water droplets, which are then discharged from the drain. Features: simple and low cost, but in addition to water
The water-lubricated air compressor does have an air-cooled type. Water-lubricated air compressors can be divided into water-cooled and air-cooled according to different cooling methods. The working principle of the water-lubricated air compressor is that during the compression process, water is injected into the main engine through the water lubrication system to perform
Ppm is the concentration unit of one part per million, which is used to indicate how much oil is left in the compressed air. The smaller the number, the cleaner the air. The water lubricated air compressor and the high efficiency filter can push this value to a very low level.
Screw air compressor maintenance standards Screw air compressor as an important equipment in industrial production, the stability of its performance and the length of service life is directly affected by the daily maintenance. In order to ensure that the screw air compressor is
The difference between an oil air compressor and an oil-free air compressor is that the working method is different and the final discharge gas is different. Oil-free air compressor: oil-free air compressor does not contain lubricating oil in this working process and is lubricated with water.
When looking for high-quality screw-type air compressors, many companies will ask: "Which is the best screw-type air compressor?" On this issue, Shanghai Grankering Group has become a highly respected product in the industry with its excellent water-lubricated screw air compressor products.
