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 continuous operation time of the air compressor depends on its type, working environment, load condition, maintenance and other factors. Generally speaking, the screw air compressor can operate continuously for 24 hours. It will automatically load when the air pressure is insufficient, and it will automatically unload when the air pressure is sufficient.
The outlet pressure of the air compressor is not fixed, but is affected by many factors. The following is a detailed answer to this question: 1. the variability of the outlet pressure of the air compressor The outlet pressure of the air compressor is not a fixed value., It will change with a variety of conditions
Air compressors need to discharge water regularly, mainly to prevent condensation from accumulating in the compressed air system, which can cause a series of equipment failures and operational problems. The following is a detailed explanation: 1. the causes of condensed water air compression process: Air Compressor
There are some differences between screw compressors and scroll compressors in terms of structure, working principle and application. Structure and working principle: Screw compressor: It is composed of a pair of parallel arrangement and intermeshing male and female rotors (ie screws). When the rotor turns
Air compressor, referred to as air compressor, is a kind of mechanical equipment that compresses air to increase its pressure energy. This kind of equipment has a wide range of applications in many fields and industries. The following is an overview of its main uses: Power source: In many industrial and production environments
In the semiconductor industry, the indicators of compressed air (CDA, clean and dry air) need to meet extremely high purity, stability and specific process requirements. The following are key indicators and analysis: 1. core cleanliness indicators Particulate matter control standard requirements: compressed air needs to be strictly limited
Twin-screw compressors can be oil-containing or oil-free, depending on their design and application scenarios. Oil-containing twin-screw compressor oil-injected twin-screw compressor: This is the most common type. In the compression process, it directly into the working chamber into the lubricating oil
The power of the 20 cubic screw air compressor is usually related to its working pressure. In general, when the working pressure is 8bar, the power of the 20 cubic screw air compressor is usually 110 kW. However, if the operating pressure changes, the power demand will also change accordingly. Example
Biological engineering equipment in the ventilation fermentation, the air requirements include the following aspects: air cleanliness: in the ventilation fermentation process, in order to avoid microbial contamination, it is necessary to ensure that the air entering the fermentation tank is clean. This usually requires air
The drainage period of the air storage tank of the air compressor needs to be dynamically adjusted according to the environmental conditions, operating conditions and equipment configuration. The specific suggestions are as follows: 1. the environmental conditions to affect the high humidity environment in rainy season or humid areas: drain water 1-2 times a day to prevent condensate from flowing back to rust the main engine.
