1, may be the air pressure meter failure.
Observation of the air pressure gauge, if the indicated pressure is insufficient, you can let the engine run at medium speed for a few minutes, the pressure is still not seen to rise or rise slowly, when you step on the brake pedal, the sound of deflating is very strong, indicating that the air pressure gauge has been damaged, this time should be repaired air pressure gauge.
2, the air compressor and the engine between the drive belt is too loose slippery or air compressor to the tank between the pipeline rupture or joint leakage.
Check whether the air compressor belt is too loose, from the air compressor to the storage tank, to the control valve inlet pipe, joints are loose, cracked or leakage.
3, oil-water separator , piping or air filter too much sediment and clogging.
Should check to see if there is too much dirt in the oil-water separator and air filter and piping to cause clogging, if it is clogged, the dirt should be removed.
Cleaning method
Air compressor running for a long time will cause the equipment to be clogged with scale, which will reduce efficiency, increase energy consumption and shorten the life. If the scale can not be removed in time, it will face the risk of equipment maintenance, downtime or scrap replacement. Long-term traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water, chemical cleaning (acid washing), etc. in the cleaning of air compressors appear many problems:
Can not completely remove scale and other deposits, and corrosion of the equipment, residual acid on the material to produce a second corrosion or corrosion under the scale, ultimately leading to the replacement of the equipment, in addition, the cleaning of waste liquids are toxic, requiring a large amount of money for wastewater treatment. Enterprises can use high-efficiency environmentally friendly cleaning agent to avoid the above situation, which has a high efficiency, environmental protection, safety, non-corrosive features, not only good cleaning effect and no corrosion of the equipment to ensure the long-term use of air compressors.
