Air compressor failure shutdown may be caused by a variety of reasons, the following are some common faults and their solutions:
high 1. exhaust temperature
temperature sensor failure: It is recommended to replace the temperature sensor.
Lubricating oil problem:
incorrect or deteriorating lubricating oil specifications: Check the oil number and replace the oil product to ensure that the old oil is completely drained before injecting new oil.
Low lubricating oil level: add oil to the 1/2~2/3 position of the sight glass.
Cooling system problems:
high temperature in the machine room: strengthen indoor ventilation to reduce the ambient temperature.
The cooler is blocked and the heat exchange is poor: check and clean the cooler to ensure its heat dissipation effect.
The cooling fan is not working properly: Troubleshoot or replace the fan.
Oil filter blockage: Remove and replace the oil filter.
2. exhaust temperature below normal
the ambient temperature is too low: reduce the heat dissipation area of the cooler or adjust the cooling system.
Too long empty time: increase air consumption to increase compressor load.
Temperature sensor or temperature control valve failure: adjust or replace the faulty component.
Excessive oil flow: Reduce the flow of the oil control valve.
High oil content of 3. exhaust gas or short lubricating oil adding cycle
the oil level is too high: check the oil level and drain it correctly, and keep it at 1/2~2/3 of the sight glass.
Clogged or damaged return line: Remove and clean the return line or replace the damaged part.
Pressure can maintain valve spring fatigue: replace the new spring.
The exhaust pressure is too low when the air compressor is running: set the pressure switch to the set value to ensure normal exhaust pressure.
4. starting current is large and tripping
start air switch problem: repair or replace the faulty switch.
Input voltage is too low: adjust the input voltage to normal value.
Star-delta transition time is too short: reset the interval to ensure a smooth start.
Main motor failure: Check the main motor and repair or replace damaged parts.
The intake valve is open or stuck: Regularly maintain and replace the intake valve repair kit to ensure its normal operation.
Loose or hot wiring: Check the wiring and rewire to ensure a safe connection.
In addition, the prevention and maintenance of air compressor failure is also very important:
regularly check whether the power supply is normal and whether the pressure sensor is damaged to avoid unexpected shutdown.
Regularly clean and replace the filter element to reduce the impact of dust and dirt on compressor performance.
Strengthen the daily maintenance and regular inspection of equipment in order to identify and deal with potential failures in a timely manner.
In summary, to deal with the failure and shutdown of the air compressor, it is necessary to diagnose the specific failure phenomenon and take corresponding solutions to ensure the normal operation of the equipment and extend the service life.
The air pressure range of air compressors varies according to types and application scenarios. The common range is between 0.7MPa and 1.25MPa, which can be specifically divided into the following categories: 1. low-pressure air compressors are classified according to exhaust pressure: exhaust pressure ≤ 1.0MPa, which is suitable for occasions with low air pressure requirements, such as air pressure
Question: What is the relationship between the exhaust pressure and the flow rate of the 22kw air compressor? Answer: The higher the pressure, the lower the gas flow rate. Take the water-lubricated oil-free screw air compressor produced by GW22A/W as an example: 0.8MPa pressure row
Air compressor blowing out of the gas containing moisture is a relatively common problem, which may be due to a variety of reasons. In order to solve this problem, the following measures can be taken: 1. check and maintain the drainage system to discharge condensate regularly: in the air compressor's gas storage
When discussing the durability of air compressors, oil-free air compressors and oil-free air compressors have their own unique features, and the water-lubricated screw air compressors produced by Shanghai Granklin Group have unique advantages. This discussion provides a new perspective. Traditional oil empty
Water lubrication and dry oil-free methods have their own advantages and applicable scenarios, so it is impossible to generalize which is better. The following is a comparison between the two: Advantages of water lubrication: High purity Output: Water-lubricated air compressors use water as a lubricant, which can remove the compression process
Wine companies do use air compressors, which play an important role in wineries, from fermentation control in the brewing process to packaging and transportation. The following is a detailed description of the use of air compressors by wine companies: the application scenario of 1. air compressors
1. According to its principle, it can be divided into volume type compressor and speed type compressor. Volume type is divided into: reciprocating compressor, rotary compressor; speed type compressor is divided into: axial compressor, centrifugal compressor and mixed flow compressor. Household today.
Generally, the vibration value and vibration speed of the motor will be measured when the motor is empty. The general vibration range of the motor is within 3 channels (that is, less than or equal to 0.03). 75kw air compressor standard vibration value: vibration intensity standard ISO2372(10-1K
Permanent magnet variable frequency air compressor is a kind of air compressor with permanent magnet synchronous motor and variable frequency control technology. It combines the high efficiency performance of permanent magnet motors with the flexibility of variable frequency control to achieve energy efficiency optimization and precise control in the air compression process. Specifically, Yong.
Granklin oil-free air compressor is suitable for nitrogen pressurization and oxygen pressurization, and has been widely praised in the chemical, medical and food industries. Oil-free air compressor is divided according to whether compressed air contains oil or not, corresponding to oil air compressor or micro-oil air compressor.
