Comparison of total oil-free scroll air compressor with other oil-free machines

Structure mode Single host can be used in parallel with multiple host units to achieve the required large exhaust volume and modular configuration
The head speed is 10000∽20000r/min, which is prone to failure, and the noise and vibration are 3000∽3500 r/min, low fault, super quiet, and no vibration can be felt
 
Starting current The starting current is up to 8 times the operating current, which has a great impact on the life of electrical components, increases energy consumption, and causes impact on the power grid.
When the gas consumption meets the requirements, it is necessary to continue to run without load to do work and increase the power consumption. The line speed is very low (2m/s), the required starting torque is small, so the starting current is very small, the impact on the life of the whole machine control system and electrical components is small, and there is no impact on the power grid, and the energy consumption is reduced.
When the gas consumption meets the requirements, the sequence is directly started and stopped, and there is no need to do work without load operation, and the electric energy saving is obvious.
 
reliability  
 
Generally, any component in the host is damaged, and the entire equipment fails, affecting the gas supply. Very high, modular multi-host combination design, to achieve energy-saving operation at the same time, but also through the load ratio of different hosts to automatically switch the running time, a single host module due to the fault of the stop use, does not affect the normal use of other modules, thus improving the reliability and practicality of the whole machine.
Online maintenance of a single unit, if there is a fault, can not provide a gas source. Need backup When a single host fails, online maintenance or repair can be realized, and each host unit can be used as the main and standby units sequentially, without affecting the operation of other hosts, and can realize the continuous supply of air sources without backup
Maintenance cost High maintenance cost, especially when replacing the machine head The maintenance cycle is long and simple, basically maintenance-free, the whole machine parts are few, the consumables required are less, and the maintenance cost is low
Nearby installation The noise is high, it is not suitable for nearby installation The noise is low, because the noise is extremely low, it can be placed in the place you think is convenient to achieve direct gas supply on site, which not only saves the pipeline, but also saves the energy consumption loss caused by the long pipeline.
Machine layout requirements The machine is large in size and high in noise, suitable for setting up an independent air compressor station to be placed away from the work site Small and silent, it can be directly placed at the air point, and even in clinics and laboratories
Pipeline requirements need to configure special pipelines, resulting in long pipelines, high installation requirements, high investment and low pressure loss, can be arranged nearby, can save construction costs and small pressure loss, can effectively save energy
Equipment requirements need external filtration and purification equipment, external pipe network, increase the installation cost, high cost, line damage large and small gas volume, can be fully built-in machine to save space, reduce the cost of pipe network
Personnel requirements require special supervision, which increases personnel costs and does not require full-time personnel supervision
Forced frequency conversion concept Inverter models are expensive. After frequency conversion, the rotor speed decreases, and the energy consumption per unit gas volume increases, resulting in the operating cost after frequency conversion does not decrease. Professional stepped control technology, according to the downstream gas consumption to automatically adjust each head start and stop, to achieve the optimal operation of the entire oil-free system, and to achieve the main and standby units to work alternately, the operating cost is very low.
Water-lubricated oil-free machine 1. Star wheel is generally non-metallic, easy to deform, vulnerable parts, and low volumetric efficiency
2. With the increase of operating time, the star wheel of the water-lubricated oil-free machine wears out, which will lead to a decrease in exhaust volume and reduced efficiency, generally reducing the exhaust volume by 10% every 3000 hours
3. There are many moving parts (there are three rotating axes), the fault will increase relatively, and the noise is large
4. Water lubrication reduces the exhaust resistance of the system due to the need for water filter and air-water separator
Piston oil-free machine 1, 8 times oil-free scroll machine moving parts, failure rate, and noise is very large
2. Lubricating oil needs to be added to the crankcase, and the air cavity is only isolated by a sealing ring
3. Due to the addition of chemical Teflon to the surface of piston rings and other components, chemical toxic gases will be volatilized as the temperature rises during work, so it is only suitable for industrial-grade oil-free occasions
