Vortex air compressor/Oil-free air compressor/Screw Compressor
Vortex air compressor
Its working principle is the use of dynamic and static turntable relative to the formation of the open volume of the continuous changes in the volume, to achieve the purpose of compressed gas.
1. The vortex air compressor's noise is lower than any other air compressor.
It can be placed directly in the workshop, the interference of workers is minimal. Completely can omit the air Compressor special machine room. Because of the low noise, you can place it at your convenience, without having to place the mainframe in a far-away building in order to isolate the high noise, thus saving not only the cost of construction but also the long-distance installation of the trachea. Can avoid noise to trouble themselves and neighbors.
2. Maintenance costs lower than any air compressor, because the vortex air compressor itself is no wearing parts, the unit performance is excellent, automatic control is reliable so users simply need to clean the filter on both sides of the body, according to the standard timing of oil and filter (Running only 2000 hours), you can safely use the scroll air compressor. Do not like the use of other air compressor, and then may occur at any time to replace the wearing parts of the expense (this cost is a lot of accumulated), but also to avoid the stagnation of the failure to bring you the economic losses!
Electricity is the maximum cost of air compressor operation. For example, a 2m³ / min machine, one-year run 4,000-5,000 hours. vortex air compressor can save you 1 million yuan. Users only need to sweep on both sides of the body of the filter. According to the standard regular replacement of oil and filter ( 2000 hours once time ).

Piston compressors
Piston compressors are volumetric compressors whose compression element is a piston that reciprocates in the cylinder.
Piston air compressor has the advantage of simple structure, long service life, and easy to achieve large capacity and high voltage output. The disadvantage is that the vibration is large, the noise is large, and because the exhaust is intermittent for the output pulse there is a need for a gas tank.
Air-cooled air compressor
Air-cooled is the use of aluminum cooler forced convection through the fan to achieve the effect of cooling oil
The advantages of air-cooled air compressor:
1. There is no water cooling system of equipment pre-investment, maintenance and long-term dependence on the circulatory system and water quality.
2. Do not need to regularly for the air compressor water cooler cleaning and maintenance, reducing the risk of maintenance due to shutdown.
3. Reduce the cost of pre-investment and equipment operation.
4. The use of air-cooled way to pay attention to matters:
Air-cooled with the dependence on the air, the early work is to produce wind shield, the air compressor into the exhaust out of the engine room room, to avoid high temperature days due to cooling air in the engine room caused by over-temperature shutdown.

Oil-free air compressor
Oil-free air compressor is the main body of the air supply device, which is the primary motor mechanical energy into gas pressure energy device, is the compressed air pressure generating device.
Air compressor with oil and without oil are generally refers to the air compressor exhaust gas discharge of the amount of oil. Oil machine generally has a large oil content, oil-free oil content of 0.01ppm, so use this oil content to distinguish between the air compressor oil and oil-free.
Advantages
First of all, the material itself does not contain oil-based material. The work does not need to add any lubricants. So greatly improving the quality of the air discharged.To the user's need for supporting equipment security also has a guarantee, unlike oil air compressor, because the discharge of gas containing a large number of oil molecules, will be supporting the user's equipment to bring different degrees of corrosion, so the choice of oil-free mute air compressor to the quality of the guarantee is necessary.
Second, the silent oil-free air compressor maintenance is more convenient and simple. As we all know, some of the oil compressor used in the process needs to be regularly replaced or refueling machines. And some air compressor have fuel injection, oil leakage phenomenon. It's not good for the environment. The user needs to take time to clean up , Which will increase the relative workload of the user. Compared with such air compressors, oil-free mute air compressor is basically no time to users to maintain, because it does not add a drop of oil, automatic pressure sensor switch will be based on your use of gas and automatically start or stop.
Screw Compressor
Screw Compressor is a rotary positive displacement compressor.
In which two rotors with helical gears engage each other, so that the volume of two rotor meshing place from large to small, thereby compressing and discharging the gas.
The screw compression components of the air compressor using the latest CNC grinder internal manufacturing, and with the online laser technology, to ensure that the manufacturing tolerance is accurate and incomparable. Its reliability and performance to ensure that the operating costs of the compressor has been extremely low during the period of use.
The basic structure of the screw compressor is shown in the following figure. Usually the thick tooth-shaped called the male rotor. The thin tooth-shaped called Female rotor. Generally the male rotor is connected with the prime mover, and the female rotor is driven by the male rotor. The ball bearing on the exhaust end of the rotor makes the rotor to be positioned axially and withstands the axial force in the compressor. In the compressor body at both ends, respectively, to open a hole. One for suction, called an suction hole, and another for exhaust, called exhaust hole.
Advantages
(1) the product specifications are relatively easy, in a certain range of air, the rotor diameter, shape can be maintained and only need to screw the rotor lengthened to shorten the demand for different air volume, this feature can reduce manufacturing costs to help the market competition ability.
(2) Similar to the reciprocating air compressor with a fixed displacement air compressor common characteristics, exhaust pressure has a wide range of changes.
(3) screw air compressor body structure is not complicated, in the continuous use of the performance is also quite good, while the reciprocating air compressor significantly reduced a lot of consumable parts, with easy maintenance advantages.
(4) Screw air compressor noise can almost be said to be the highest of all air compressors. The noise depending on the size of the wind volume, often more than 100dbA, so the screw air compressor must be equipped with noise enclosures, and therefore Giving a more beautiful impression.
(5) You can use throttling control.
Disadvantages
(1) The gap between the male and female screw must exist, resulting in an unsatisfactory gas tightness, which is the main reason why the energy efficiency of the oil-free screw compressor is poor. The oil-injected screw air compressor solves this problem, but the pressure loss caused by the oil filter has increased the consumption of a certain proportion of energy.

Air intake air filter
The air cleaner is a part of the air filter that filters out the air dust, and the filtered clean air enters the screw rotor compression chamber. Due to the internal gap of the screw machine allows only 15u within the particles filter out. If the air filter plug is broken, a large number of particles larger than 15u into the screw machine cycle, not only greatly shorten the oil filter, oil separation core service life, but also lead to a large number of particles directly into the bearing cavity, speed up the bearing wear to increase the gap in the rotor and compression efficiency.
Oil filter
It is strictly prohibit to use the oil filter for extended limit.Or the filter blockage is serious, the pressure exceeds the bypass valve to accept the limit, the bypass valve automatically opens, a lot of dirt, the particles will be directly into the screw inside the main engine, causing serious consequences.
Oil and gas separator
Oil and gas separator is the separation of the screw oil and compressed air components, normal operation, the life of the oil and gas separator in 3000 hours. But the quality of lubricating oil and air filtration accuracy influence its service life.
Oil and gas separator
Oil and gas separator is the separation of the screw oil and compressed air components, normal operation, the life of the oil and gas separator in 3000 hours. But the quality of lubricating oil and air filtration accuracy influence its service life.The oil and gas separator must be replaced after the expiration or before and after the pressure difference exceeds 0.12Mpa. The oil and gas separator must be replaced after the expiration or before and after the pressure difference exceeds 0.12Mpa. Otherwise it will cause the motor overload, oil and gas separator damage running oil. Replacement method: Remove the control tube fittings installed on the tank cover. Remove the oil and gas bucket cover into the oil and gas bucket inside the return pipe, remove the oil and gas bucket cap fastening bolts. Remove the oil and gas bucket cover, remove the oil fine. Remove the asbestos pad and dirt sticking to the upper cover. Load the new oil and gas separator, pay attention to the upper and lower asbestos mat must be stapled book, pressing the asbestos mat must be neatly placed, otherwise it will cause a pad. Put back cover, back tubing, control tube as is, check for leaks.
Oil replacement
The quality of the screw oil has a decisive effect on the performance of the fuel injection screw machine. The good oil has good anti-oxidation stability, fast separation, good cleaning efficiency, high viscosity and good corrosion resistance. Therefore, the user must use the special screw Oil.
The new machine running period of 500 hours after the first oil replacement, after each operation 2000 hours to replace the new oil. It is best to replace the oil filter at the same time. Use shortened replacement cycles in harsh environments. Replacement method: start air compressor running for 5 minutes, so that the oil temperature rose to 50 ℃ or more, oil viscosity decreased. Stop running, when the oil and gas drum with 0.1Mpa pressure, open the bottom of the oil tank valve, connected to the storage tank. Oil drain valve should be slowly opened, so as not to bring pressure with the temperature of the oil splashing stains. And other lubricants into the drop after the drop valve. Unscrew the oil filter, the pipeline of lubricants at the same time let go, put on a new oil filter. Open the mouth of the screw plug, into the new oil, so that the oil level in the oil mark line range, tighten the screw plug, check for leaks. Lubricants in the use of the process must always check and found that the oil level is too low should be added when the new oil, lubricants must also be used in the discharge of condensate, the general situation once a week, in high temperature climate should be 2-3 days Emissions once. Stop more than 4 hours, in the case of oil and gas bucket without pressure to open the release valve, drain condensate, see the oil out of the rapid closure of the valve. Lubricants are strictly prohibited mixed use of different brands, avoid excessive use of lubricating oil, or lubricating oil quality decline, poor lubrication, flash point reduction, easily lead to high temperature shutdown, causing oil spontaneous combustion.
