In the previous advantages and disadvantages of the screw air compressor, it was said that compared with the piston air compressor, its stability is better and the vibration is relatively small, but in special cases, there will be large vibration. So what are the reasons for this?
1. The machine bolts are loose;
2. The oil filter is blocked without replacement for a long time;
3. The gap between the yin and yang rotors does not meet the requirements;
4. Large deviation of wheel center;
5. The bearing is worn;
6. Air compressor oil is insufficient.
Processing methods in turn are:
1. Tighten the loose bolts;
2. Replace the new oil filter;
3. Check whether the rotor is worn, and if it is necessary to repair it again, do dynamic balance check, etc;
4. Re-adjust the wheel center;
5. Replace the bearing;
6. Add lubricating oil;
the noise of the air compressor is also one of the common faults. The main reasons for the metal impact sound, friction whistling sound, etc. are mainly in the following aspects:
1. The intake valve is not completely closed or the large intake volume causes the check valve to vibrate;
2. Loose gear bolts;
3. Lack of oil during the operation of the air compressor;
4. The belt of the belt drive air compressor is loose and caused by slipping;
processing methods in turn are:
1. Adjust the intake valve;
2. Tighten the loose bolts;
3. Add lubricating oil;
4. Replace the three drive belts.
Air compressor oil and gas separator filter element, also often called air compressor oil, oil and gas separator, oil and gas separation filter element, oil mist filter or oil filter element filter, its main functions can be summarized as follows: main functions oil and gas separation: air The core of the compressor oil and gas separator filter element
The water-lubricated oil-free frequency conversion screw air compressor of Shanghai Granklin Group adopts advanced water lubrication technology and permanent magnet frequency conversion technology, and has the advantages of high efficiency, energy saving, environmental protection, stable operation, low noise, and convenient maintenance. Specifically, it does not need to add
Question: What size of air compressor is needed per hour for 75 cubic meters of air volume? Answer: If the air volume required per hour is 75 cubic meters, then 1.25 cubic meters per minute. If the Granklin water lubricated air compressor is 11kw, the gas production of 8kg of conventional pressure can meet the requirements. Snail
The maintenance cycle of a screw air compressor depends on many factors, including the type of equipment, the working environment, the frequency of use, and the manufacturer's recommendations. The following are some general guidelines on the maintenance cycle of screw air compressors: 1. first maintenance for newly purchased screw air
Air moisture content (in ppm) is not a fixed value, but a dynamic parameter that is influenced by a variety of factors, including temperature, humidity, geographic location and climatic conditions. The following is a detailed analysis: 1. definition and unit definition of air water content: air water content refers to the evaporation of water in the air.
Whether the exhaust fan in the air compressor room needs to be explosion-proof depends mainly on the specific environment of the air compressor room and the risks that the exhaust fan may encounter. The following is a detailed analysis of this problem: air compressor room environment characteristics: air compressor room in the normal operation process, exhaust
In many aspects of modern industrial production, screw air compressor as the key equipment of gas compression and power transmission, its performance stability and technical advancement play an important role in ensuring production efficiency and product quality. In many air compressor brands
In the lithium battery industry, the application of compressed air runs through multiple core links from raw material processing to battery assembly, and its importance is no less than power supply. The following are the six key application scenarios and technical details of compressed air in the lithium-ion industry: 1. electrode material preparation stage
In response to the question of "how much power air compressor is needed for 12m 3/min gas consumption", the following aspects can be answered: estimation of required power: according to publicly released information, under normal circumstances, for exhaust pressure of 7-8kg (
Medical air compressors are widely used in medical institutions. They are mainly used to provide a clean and stable gas supply to meet the needs of medical equipment and patients. Specifically, the medical air compressor can be applied to the following departments: respiratory department: call
