Common fault phenomenon
Common faults of air compressors
- Common fault phenomenon
●The compressed air pressure at the gas point is insufficient; ●The compressed air pressure at the gas point fluctuates too much;
The quality of compressed air at the point of use is poor (water, oil, and dust are heavy);
●The life of the filter element of the pipeline filter is too short; ●The life of the adsorbent of the adsorption dryer is too short;
iCold-connected king dryers often experience high-quality or low-pressure protective shutdown
i The air compressor is overloaded more frequently: : The more serious the shortage of the sinus compressor is
The main reason for the failure.
●The gas pipeline is too long and too small; ●The selection of the air compressor is unreasonable; .
●The pipeline filter configuration is unreasonable; ●The processing capacity of the refrigerated dryer is unreasonably configured;
●There is no gas storage tank or the configuration is too small: ●The installation process is unreasonable.
About Air Compressor Reconstruction
Under normal circumstances, the air compressor unit in use needs to undergo technical transformation mainly for two reasons.
The actual working conditions cannot meet the basic operating requirements of the unit, so that the unit cannot operate normally.
There is a defect in design or manufacture and it is necessary to modify it.
- The actual working conditions of common users cannot meet the basic requirements of the unit
The ambient air of the air-cooled unit is too dusty or too humid, the cooler is easily dirty and blocked, and the cooling effect is poor, resulting in the operating temperature of the unit and the
The exhaust temperature is too high, the unit and system cannot operate normally; .
The ambient temperature of the unit is too high, causing the operating temperature and exhaust temperature of the unit to be too high, and the unit and system cannot operate normally
Due to the poor water quality of the water-cooled unit, the cooler is easy to scale and the cooling effect is poor, resulting in high operating temperature and exhaust temperature of the unit.
Groups and systems are not functioning properly;
The ambient air of the unit is too dusty or too humid, and the air filter element is easily blocked or perforated, resulting in extremely frequent replacement of the air filter element or oil, oil, etc.
The life of oil filter and oil separator is severely shortened;
●The ambient air of the unit contains heavy acid gases and other harmful components, which seriously shorten the service life of the related components of the unit.
Fourth, the common unit has defects in the design
There is no capacity adjustment control for the gas production of the unit. When the actual gas consumption fluctuates greatly, the unit will be loaded and unloaded more frequently:
The specifications of the main engine do not match the designed displacement of the unit, and the low speed of the main engine leads to a short bearing or shaft seal life:
There is no filter device for the loading control air flow and the diameter of the solenoid valve is too small, which causes the control cylinder or piston of the unloading valve to be easily dirty and blocked, and the sealing element
The wear is faster; if the diameter of the solenoid valve is too small, it may be difficult for the unloading valve to open after the seal is slightly worn.
V. Transformation for unreasonable system configuration
Equipment addition or update: mainly for the insufficient air compressor exhaust configuration or the insufficient processing capacity and accuracy of purification equipment, compression
The air can not meet the normal air requirements of the system;
●Renovation of compressed air pipeline: mainly for the poor quality of compressed air caused by unreasonable equipment installation process and pipeline installation.
Systems with high compressed air losses.
Unreasonable transformation for air compressor unit design and use environment
●Control system transformation: mainly for units with defective control system design and hidden dangers of stable operation;.
, Cooler transformation: mainly for units that often have high temperature trips due to cooling reasons. Water-cooled chiller retrofit is right
For units with small cooler configuration or poor user cooling water quality, the transformation of air-cooled coolers is mainly for small cooler configurations.
Or units with poor user air environment;
●Reconstruction of exhaust volume and pressure level: mainly for units with improper unit selection, increase the exhaust volume of the unit or change it through transformation
The rated exhaust pressure of the unit maximizes the operating efficiency of the unit.
Air filter modification: mainly for the excessive dust in the ambient air or the unreasonable design of the air filter, which leads to the life of the air filter element
Units that are too short or maintenance work is too frequent. .
