Compressed air system is the most widely used in industrial field one of dynamic service source. In steel, metallurgy, chemical industry, building materials, textile, chemical fiber, automobile, ship, paper, packaging, food, medicine, military industry, such as navigation days have lei quantity in manufacturing applications. In most enterprises of compressed air energy consumption accounted for 10% of the total power consumption to 10%.
The cost of the compressed air system
For system throughout the life cycle, the air compressor running electricity is the main cost spending.
Example: the 250 kw air compressor, running 8000 hours a year, electricity price is 0.7 yuan, equipment service life of 10 years, for example,
Calculate fees are as follows:
Equipment purchase cost: 400000 yuan (the market mainstream brand air compressor and the person who purchase price)
Ten years equipment regular maintenance cost: 60000 = 600000 yuan/year by 10 years
Ten years operation electricity: 250 kw. H * 8000 H * 10 * 0.7 = RMB 14 million per year
Three charges together to: 15 million yuan
Pipe network layout and piping configuration is not reasonable, lead to energy loss
System leakage caused by pipeline transportation inefficiencies
, gas equipment at the end of the unreasonable use of waste energy

ECOWELL efficient screw air compressor
North American compressor institute of the latest scientific research achievements of application - Y3 screw type line, adopting two stage compression technology, entrust the international famous screw compressor manufacturer specialized in manufacturing. All series of products through the national certification of energy efficiency.
Product has the following features:
Reliable, high efficiency, energy saving
(1) isothermal type two stage compression screw host
(2) Y3 new rotor type line, patent design
Advantages: lower compression ratio and reduce the bearing load
Each level due to low compression ratio, compression process and reduce the load of bearing, prolong the service life of bearing.
Advantage two, isothermal compression, reduce heat compression
Two stage compression efficiency is one of the reasons why the interstage coolant jet curtain design. To a level of compressed air spray mist cooling agent, can achieve unexpected air cooling effect. This compressed air into the secondary compression stage before, and reduces the temperature of the air, greatly saves energy needed to compress. And the use of coolant jet curtain can dispense the coolant in the middle.
Advantage three type line, unique design, primary and secondary rotors are running at optimal tip speed
This type of line design can obtain the best compression efficiency, over 20% of energy than a conventional screw host.
Advantage four, SKF roller bearing and angular contact bearing the joint design, by the angular contact bearings bearing axial force
This design can effectively ensure reliability and running stability of the rotor, the dynamic balancing experiments, rotor radial deviation less than 0.03 um.
Advantage five, using electronic fuel injection allocation system
The system automatically adapt to the environment temperature, the air, temperature of cooling water, the change of the flow and pressure, to ensure the temperature control in the compression of the host within a reasonable range of 80 ~ 100 ℃.
(3) using efficient high torque motor
Motor parts performance indicators:
Manufacturing standards: NEMA standard
Insulation class: F, class B temperature rise
Protection grade: IP54 / IP23
Rated speed: 1485/2980 RPM
With overload, open phase protection function
(4) vortex form efficient oil and gas separator, rapid separation, minimal pressure loss
Super efficient two stage to exhaust separation filter, oil and gas separator filter selects the permeability of the excellent and durable nano materials, the service life of up to 8000 hours, fold structure increased the filter area, little flow resistance; Can guarantee under the premise of exhaust efficiency against losses, make exhaust oil content is lower than 2 PPM.
(5) choose this type of bearings SKF overloading
Bearing for the rotor in the process of rotational loading (axial and radial force), guarantee of the gap between the screw rotor, thus bearing is important in the moving parts of screw host.
ECOWELL compressor with Swedish SKF company B - 10 e (overloaded wear-resisting bearings), design service life of 130000 hours.
Supporting air compressor host Yin and Yang of rotor inlet end USES the cylindrical bearings, exhaust end the use of the back-to-back angular contact bearings to withstand and/discharge when the axial and radial force.
(6) direct drive, gearless consumption loss, high transmission efficiency
Using high-performance KTI elastic coupling, effectively combines the advantages of belt and gear coupling, and overcome their disadvantages: high transmission efficiency, and motor drive ratio of 1:1, effectively protect the motor. Main features:
, vibration absorbing ability;
, torque is maximum;
, but the radial tear open outfit;
Less, the connecting bolt (10);
Low, assembly and to the requirements.
(7) the air-filled type inverter centrifugal fan
The correct cooling system design is a key to ensure the reliability of the compressor. ECOWELL compressor cooling fan adopts frequency conversion control, large flow design, according to the environmental temperature and exhaust temperature automatically adjust the motor speed, low power consumption, low noise, long service life.
