1. oil free air compressor current is too high:
the common causes of this failure are mainly the following:
1. The host fails
2. Exhaust pressure is too high
3. The voltage is too low: Generally, the power of the oil-free air compressor is rated. Therefore, according to the formula, if the voltage is too low, the current will definitely be too high. This is well understood.
2. oil-free air compressor keeps working, but the gas supply is still insufficient:
common causes of this failure are:
1. Air leakage: The judgment method is to listen to the external pipes of the air compressor, the air supply pipe of the air compressor on the air storage tank, the one-way valve, safety valve, pressure switch and other joints for air leakage. If so, it must be handled.
2. Wear of the head leather bowl: The service life of the general leather bowl is about 3 years, and it must be replaced after the expiration date.
3. Exceeding the rated flow
4, the machine overload work
3. oil-free air compressor works intermittently and the air supply is insufficient:
the causes of this failure are:
1. Start capacitor leakage. When leakage occurs, the compressor head can still be started, but the speed is slow and the current is large. Due to the large current, the head heats up quickly, and the head will be protected and shut down soon. This problem can be changed to a new one, but it should be noted that UF numbers should be the same, too large or too small is not good.
2. Insufficient voltage. There is a buzzing sound at the start. If the operating current is too large at this time. Oil-free air compressor head working minimum voltage is 200V, below this voltage head is difficult to start, frequent start will cause the air compressor head temperature rise. Final circuit protection shutdown. Until the temperature drops and turns on again. For areas with frequent voltage fluctuations, it is recommended to install an automatic voltage regulator.
4. oil-free air compressor can work, but the noise is obviously larger than the original:
the causes of this failure are:
1. The air compressor fixing device or accessories are loose
2. Abnormal operating current
3. The motor bearing is seriously worn
4. The cup is damaged
the 5. air compressor must put the air pressure of the air storage tank to zero air pressure before starting work every time it works, otherwise it cannot be started. When the machine is powered on, you can see that the machine head turns very slowly, there is a buzzing sound, and the current is also large:
the cause of this kind of failure is probably that the one-way valve is blocked. The one-way valve of the oil-free air compressor is installed between the air compressor outlet pipe and the gas storage tank. The main function is to allow the gas from the machine head to only enter the gas tank. The gas from the gas tank cannot come out. Inside is a spring and a film. If dirt sticks to the film, it will cause reverse air leakage, then the second start of the machine head will be pressed by high pressure and unable to start. The solution is to use a plate to open the valve cover behind the one-way valve, please wash it and put it back as it is.
Structural aspect: The twin-screw air compressor has few moving parts and simple structure. The rigidity of the male rotor is higher than that of the female rotor, but the male rotor also bears most of the load. The rigid load ratio of the male and female rotors is close, the deformation is uniform, and the volume coefficient is high. The single screw air compressor has three rotating shafts
Air compressor type variety, wide range of uses, and different types of air compressor, the lubrication requirements vary greatly. In the air compressor parts, the lubricating oil plays a role in preventing wear, sealing, and cooling, minimizing the influence of air on the viscosity of the lubricating oil and the reaction between additives and air, so as
I believe everyone has experienced the air compressor host or motor overload, maybe it is a small problem for you, maybe you are troubled by this fault. The reasons for the failure are: 1. The voltage is too low: the rated working voltage of the general compressor is 380V, and the upper and lower levels are allowed to float at about 5%.
Linyi Air Compressor Factory Screw Machine Quotation? Linyi, a prefecture-level city in Shandong Province, is located in the southeast of Shandong Province, the west bank of the Yellow Sea, the junction of the Yangtze River Delta Economic Circle and the Bohai Rim Economic Circle, the national key development area of the East Longhai Sea and the port industrial belt in southern Shandong Province. Granklin air compressor brand combines the "power" of air compressor with the "application" of pneumatic tools to achieve a complete screw air compressor with integrated power and application, which has won the support of our customers.
View detailsOf course, it is good to be oil-free. It is clearly arranged for you from the price. Oil-free is several times the price of oil (not the kind of small piston air compressor). The compressed air produced by the oil air compressor is with a small amount of oil, and it must be filtered, and it is still endless.
Granklin Group's water-lubricated oil-free screw compressors, from design to manufacture, everywhere reflect our pursuit of energy saving, cleanliness and environmental protection. From water lubrication to non-corrosive main engine shell, from stainless steel screw to silicon carbide sliding bearing that never rusts, from high-efficiency air filter to precision lubrication water filter, we ensure that XR parts are oil-free working design, we have always believed: professional casting quality, quality casts the future!
Shanghai granklin group water lubrication air compressor manufacturer, as a member of the air compressor industry, we talk about other types of air compressors, such as dry oil-free air compressors. Dry oil-free air compressor its product advantages are:
View detailsThe replacement cycle of air compressor oil is divided into three situations: 1. Mineral oil is replaced every 3 to 4 months; 2. Semi-synthetic oil is replaced every 6 to 8 months; 3. Fully synthetic oil is replaced every 10 to 11 months. The air compressor shall have the following conditions
Therefore, the suction pressure of the compressor can be appropriately increased, and a high-efficiency cyclone inlet separator can be added in one stage of suction to further eliminate the resistance of the air inlet pipe network, and a higher suction pressure can be obtained while ensuring sufficient processing air. The pressure drop between the 1.2 compressor sections is reduced. The pressure drop between the compressor stages is also an important reason for the power consumption of the compressor.
Condensed water is a big killer of air compressor. If it is not discharged in time, it will rust the inside of the unit, reduce the performance of lubricating oil and affect the operation of the unit. So how is the condensate produced? How to discharge it? Air compressor condensate water mainly comes from the air. Air compressor suction
