Oil-free rotary air compressor and oil-free screw air compressor have their own unique advantages and disadvantages, which is better depends on the actual application scenarios and needs.
The advantages of oil-free rotary tooth air compressor include:
oil-free, so there is no need to replace the air compressor oil, maintenance-free, and the compressed air does not contain oil, which greatly improves the cleanliness of the air source.
The noise is low, and the noise is less than 50 decibels after starting up, which is equivalent to the noise of a refrigerator.
High efficiency and energy saving, the same power of the oil-free silent air compressor air volume is about 2 times the traditional air compressor.
Long service life, the key moving parts are self-lubricating materials imported from Germany, and the design life of the whole machine is more than 10 years.
High safety, using the EU standard special relief valve.
However, the oil-free rotary tooth air compressor also has some shortcomings, such as: high requirements for moisture, the need to rotate the machine frequently to avoid the host for a long time without failure; high exhaust temperature, the operation need to pay attention to avoid burns; after a certain period of use may be a failure, resulting in the replacement of the host, high maintenance costs.
Oil-free screw air compressor features include:
the structure is superior, the symmetrical position of the two star wheels of the single screw air compressor on both sides of the screw can offset each other's axial force and radial force, and has the characteristics of small unbalanced inertial force.
High efficiency, due to the large specific heat of water, and similar to isothermal compression in the working process, making the single screw air compressor work efficiency is very high.
Low noise, the use of polymer material star wheel and motor and screw direct design to reduce noise.
Small vibration, with superior power balance system, can suppress the vibration source, smooth operation.
Zero discharge, only the lubricating water similar to the drinking water standard in the machine participates in the cooling, sealing and lubrication of the compression process, and there is no "three wastes" discharge.
Can carry out intelligent monitoring, real-time monitoring of the compressor, timely alarm and designated computer display.
On the whole, both have the advantages of oil-free, high efficiency, and low noise, but the oil-free rotary tooth air compressor focuses more on high efficiency, energy saving and long service life, while the oil-free screw air compressor focuses more on superior structure, Zero emission and intelligent monitoring. The specific choice of air compressor depends on the actual needs and application scenarios. For example, in industries with high air quality requirements, such as pharmaceuticals, food, electronics, etc., oil-free rotary air compressors may be more suitable; and in situations where zero emissions and intelligent monitoring are required, oil-free screw air compressors may More advantages.
The screw air compressor will not stop all the time. It will also need rest and maintenance after working for a period of time like other machines. Although the screw air compressor has high stability and durability, long-term continuous operation may also cause the equipment to overheat,
The standard of exhaust oil content of screw air compressor is usually measured by the number of milligrams of oil per cubic meter of compressed air (mg/m & sup3;). Different applications and industries have different requirements for the quality of compressed air, so there will be different oil content standards.
The drainage interval of the gas storage tank shall be determined according to the humidity of the gas environment, the operation time of the equipment, the quality requirements of compressed air and other factors. There is no fixed standard, but the following methods can be used to determine and formulate a reasonable drainage plan: 1. the core factors affecting the drainage frequency
Mainly the function is different. Oil air compressor is the general use of electronic, printing, coating gas factory, oil-free air compressor is food, medicine, hospitals and so on. Oil-free air compressor is cheaper, while oil-free air compressor is more expensive. As long as it is normally maintained, it is quite durable.
Screw air compressor to choose frequency conversion or power frequency, this is really a bit "tangled" problem, because they each have their own good. However, it doesn't matter, let's analyze it slowly together! The power frequency screw air compressor is like a stable and reliable & ld
As a commonly used power equipment in the industrial field, the energy consumption of air compressor has always been the focus of attention of enterprises. According to industry research and actual case analysis, the main reasons for air compressor power consumption are the following categories: 1. equipment itself factors equipment old or backward old technology.
The drainage operation of the screw air compressor can be carried out through the following steps: manual drainage method: close the air compressor and release the pressure: tighten the drainage valve. Shut down the oil pump. Turn the relief valve knob counterclockwise to release the inside of the reservoir
The pressure of compressed air can reach very high levels, but the specific number of kilograms (here refers to the pressure unit, 1 kilogram is approximately equal to 0.098MPa) depends on a variety of factors, including the type of compressor, design specifications, operating conditions and The required application. The following is
In semiconductor cleaning equipment, compressed air and nitrogen each play a key role, the specific role is as follows: the role of compressed air purging and cleaning: removal of tiny dust and residues: in the semiconductor manufacturing process, the wafer surface may be attached to tiny dust, particles
Belong. Class II pressure vessels belong to special equipment, and Class II vessels are also called "Class II pressure vessels". Refers to the safety technical supervision and management of pressure vessels, according to the pressure grade of the vessel (see "pressure vessel & rdquo
