I think only the internal structure of the screw air compressor is quite understand and understand the function and role of various accessories, in order to find the cause of the failure in time. The following small series for everyone to list the screw air compressor parts failure on the impact of air compressor equipment, so that we can timely judge the cause of the failure, in order to deal with in a timely manner.
Influence of oil filter blockage of 1. screw air compressor on machine
1. Rotor outlet temperature rises;
2. The oil life is reduced.
(1) The normal oil filter pressure difference gauge is less than 1kg. If it exceeds, it means that the oil filter is blocked. The inspection method is: measure the oil temperature of the oil inlet cooler and the oil temperature of the oil outlet cooler. If the temperature difference is too large, it means that the oil filter is blocked.
(2) The oil temperature is often too high, which will cause the oil quality to crack faster (the normal working temperature is 75-95 ℃).
Results of 2. Screw Air Compressor Oil and Gas Separator Blocking
1. Oil tank pressure rises
2. The outlet pressure is reduced
3. Motor current rises
4. Cause the air compressor to jump
5. Cause safety valve exhaust fuel injection
6. The oil and gas separator will be damaged due to excessive pressure, resulting in the loss of cooling oil. Replace the oil-gas separator (normal pressure difference: within 0.8kg)
what is the effect on the machine when the heat sink of the 3. oil cooler is blocked
1. The rotor outlet temperature rises, resulting in tripping.
2. Overload tripping of main motor due to high temperature.
3. The fan motor is overloaded due to excessive negative pressure. Remove the cooler for cleaning and maintenance.
What is the influence of poor ventilation and heat dissipation of 4. screw air compressor station on the machine
1. The rotor outlet temperature rises and causes high temperature jump.
2. Cause motor overload.
3. Cause fan motor overload.
4. The air outlet temperature rise causes the load of the cold dryer to increase. It is recommended that customers add air ducts and exhaust systems.
What are the consequences of the failure of the 5. minimum pressure check valve to fail to close
1. After the machine starts, the oil tank cannot rise and the air compressor cannot be loaded.
2. The oil content of the outlet air increases.
3. The on-site air will flow back into the machine, causing the oil tank pressure to fail to drop when the machine is empty and causing the air compressor to spray oil after parking. Remove the minimum pressure check valve for maintenance. If it fails, replace it with a new one.
What happens when the 6. drive belt breaks?
1. The machine cannot be loaded after starting.
2. During operation, the oil tank pressure will drop to 0kg and the output pressure will stop. Check the cause of belt breakage and install a new belt.
What are the consequences of 7. the intake valve cannot be closed
1. It will cause the pressure of the screw air compressor to continue to rise after no load and cause the safety valve to exhaust.
2. The oil tank pressure rises when the vehicle is empty.
3. When the machine is shut down, the cooling oil is poured back from the air inlet. Remove the intake valve for maintenance, and replace it with a new one if it fails.
What is the effect of poor contact at the connection point of the 8. starter
1. The working current of the motor increases and causes the motor to overload.
2. Starter heating caused fault.
3. BURNED FUSE. Remove the starter for maintenance.
9. screw air compressor external power supply voltage is too low, too high or three-phase imbalance, what impact will it have on the machine
1. The supply voltage is too low will cause the motor overload.
2. The supply voltage is too high will cause the motor resistance to reduce and burn.
3. Supply voltage three-phase imbalance will cause motor overload.
It depends on your application scenarios, such as medical, chemical, food, electronics, and other industries that require higher gas requirements, then the "5 cubic screw air compressor price" and ordinary "5 cubic screw air compressor price" is very different. So what is the difference between a high standard "screw air compressor" and an ordinary "screw air compressor?
Is there really a "oil-free air compressor manufacturer" with 100% oil-free compressed gas? For companies that have not used "oil-free air compressors", it is normal that they do not understand "oil-free air compressors".
Oil-free air compressor is commonly used in water-lubricated air compressor, screw air compressor oil-free products, the current mature structure is to use water as air compressor head lubricant. Water lubrication has natural oil-free characteristics, or a very good sealing material, oil-free characteristics in the product structure of water played an important role
The oil-free screw air compressor in the factory usually needs to run all day and consume a lot of electricity. Advanced frequency conversion technology not only helps to save energy, but also makes the operation of the air compressor simple and stable. So in the choice of oil-free screw air compressor inverter should pay attention to what?
View detailsAir compressor faults and treatment methods The high temperature rise of the outlet temperature or exhaust temperature of the air compressor head is a common fault in the operation of the screw air compressor. The screw air compressor often runs at high temperature, which will seriously affect the displacement and operation of the machine.
Features and advantages of oil-free and water-lubricated screw air compressor 1. The structure is reasonable and has ideal force balance. Both sides of the screw of the oil-free air compressor are equipped with a star wheel symmetrical structure, so that the oil-free air compressor not only has no unbalanced inertial force, but also The axial force and radial force used on the screw also cancel each other to make it have ideal force balance
The current of the 1. oil-free air compressor is too high: the common reasons for this failure are as follows: 1. The main engine fails 2. The 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 public
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
There are many types of air compressors. If they are divided into two types according to the lubricating oil method: one is an oil-free air compressor and the other is an oil-lubricated air compressor. These two kinds of air compressor equipment have their own advantages and disadvantages. Today we will analyze the advantages of oil-free air compressor.
Screw air compressor pumping slow how to deal with, screw air compressor pumping slow power generally have the following reasons: screw air compressor pumping slow how to deal with? 1, the host problem. Check the air supply power of the equipment host, and close the valve behind the air tank
