What are the advantages and disadvantages of screw air compressors???

1.High reliability, few parts, no wearing parts, so it runs reliably, long life, the design life of the main head of the general screw machine is up to 30 years.

2.The operation and maintenance are convenient, the degree of automation is high, and the operators do not need to go through long-term professional training to achieve unattended operation.

3.The power balance is good, there is no unbalanced inertial force, the machine can work smoothly at high speed, and realize the operation without foundation.

4.Strong adaptability, with the characteristics of forced gas transmission, the volumetric flow is almost not affected by the discharge pressure, can maintain high efficiency in a wide range of working conditions, in the case of no change in the compressor structure, suitable for a variety of working conditions, so it is easy to finalize mass production.

5.Multi-phase mixed transportation, there is actually a gap between the tooth surfaces of the rotor, so it can resist liquid impact, and can pressure gases containing liquids, dusty gases, and easily polymerized gases.

6.The flow adjustment of the slide valve does not require backflow, which can effectively reduce energy consumption.

Oil-free screw air compressors are divided into water-lubricated and dry.

Disadvantages of water lubrication: 1) The air compressor is stable, after 40 cubic meters is limited by technology, 2) In the environment below 0 degrees, the water lubrication air compressor will freeze and cannot be used.

Advantages of water lubrication: 1) no lubricating oil 2) no coating peeling and rotor deformation 3) high purity of exhaust air, no oil 4) extremely low maintenance cost.

Advantages of dry type: 1) It is suitable for any environment and is not affected by the external environment 2) Air compressors above 40m can also be used with confidence.

Disadvantages of dry type: 1) coated, easy to fall off, maintenance time 5 years 2) rotor deformation 3) use of lubricating oil 4) extremely high maintenance cost.

Inferior rotor coatings come off after a period of operation, and the rotor is exposed to air, subjecting to airborne impurities and temperature changes. Eventually, Denier's analysis resulted in a reduction in running performance and even damage to the machine.

Oil-free, characterized by low oil content, but easy to wear because it is oil-free.

1. The coating on the oil-free screw is peeling off.

Now there are two coatings of oil-free screw machine, one is Teflon with average performance, and the other is molybdenum disulfide which is much better. Therefore, when the oil-free screw machine is not in use, it is necessary to rotate the machine frequently to avoid the main machine from being stuck when it does not move for a long time. Frequent failures where the host gets stuck are caused by these reasons.

Second, the exhaust temperature of the main engine is very high.

Generally, the exhaust temperature of the main engine of the oil-free screw machine can reach 180+, and the factory will generally do some protective measures before leaving the factory, but special attention should be paid to the high-temperature parts during operation, so as not to cause scalding or even fire danger.

3. Maintenance problems after the host is damaged.

At present, in addition to the maintenance of the oil-free host proposed by IR, other manufacturers are required to directly replace the host, and the cost of replacing the host is very high.

The above is a personal opinion, I hope it can help you.

Pay attention to Huahao Electromechanical, you can learn more about it.

First, the characteristics are different.

1. Screw air compressor features:

1) Screw air compressor has the advantages of high stability, high efficiency, low vibration and low noise.

2) The internal and external rotor and the coordination of the rotor and the casing make the return air leakage less, and at the same time, there is no gap volume and high efficiency.

3) The injected lubricating oil has the functions of sealing, cooling, noise reduction, lubrication and so on.

4) Compared with the piston machine, there are fewer wear parts and the failure rate is low.

2. Characteristics of ordinary air compressor: due to the change of pressure in the cylinder, the air enters the cylinder through the air filter (muffler) through the intake valve. In the compression stroke, due to the reduction of the cylinder volume, the compressed air enters the tank through the exhaust valve, exhaust pipe, check valve (check valve).

When the discharge pressure reaches the rated pressure, the shutdown is controlled by the pressure switch.

Second, the nature is different.

1. The nature of the screw air compressor: the screw air compressor with pre-complete configuration only needs a single power connection and compressed air connection, and has a built-in cooling system, which greatly simplifies the installation work.

2. Ordinary air compressor nature: a kind of equipment used to compress gas.

Screw air compressors use high-capacity compression assemblies with low rotor outer velocity and optimal oil injection, achieving high efficiency and reliability. The latest design ensures that the system temperature and compressed air temperature are extremely low. Optimum cooling and maximum service life of all components are guaranteed.

The yin and yang rotor and the coordination between the rotor and the casing are set, so that the gas backflow leakage is less, and at the same time, there is no residual clearance volume, so the efficiency is high. The injected lubricating oil has a sealing, cooling, noise reduction and lubrication effect, and has fewer wearing parts and a lower failure rate than piston machines. The working curve of screw compression is smooth, and the vibration is small compared to the piston machine, and the noise is low.

Cooling methods are generally divided into: water cooling and air cooling. Cooling system:

The plate-fin structure and high-quality materials are used to ensure that the cooler has high pressure resistance, high heat dissipation efficiency and good corrosion resistance. Air filter: heavy-duty, multi-stage air inlet filter, dust removal essence 1um (98% filtered), large working surface, long relative service life.

Oil-gas separator: The new generation of separator adopts a new filter material, which is more efficient, and the air oil content is less than 2ppm. Smart Controller:

All the operations and related data of the air compressor operation are displayed on the control panel, which is easy and accurate to control at your fingertips.
