Is the air compressor durable with oil? Or is it oil free and durable?

Oil-free and durable.

First, the materials are different:

1. Oiled air compressor: The oily air compressor itself contains oily substances, which will pollute the terminal equipment.

2. Oil-free air compressor: The material of the oil-free air compressor itself does not contain oily substances, which avoids the pollution of the oil-bearing machine to the terminal equipment.

Second, the gas is different:

1. Oiled air compressor: The oiled air compressor is lubricated with oil, so the final discharged gas contains oil.

2. Oil-free air compressor: The oil-free air compressor is lubricated with resin material, so the final discharged gas does not contain oil.

Air circulation system.

When the compressor is working, the air is sucked in through the self-cleaning air filter, and through the PLC automatic cleaning filter, the air enters the first-stage compression after the automatic adjustment of the imported guide vane, and the gas temperature after the first-stage compression is higher, and enters the intercooler for cooling (water in the pipe, outside the gas pipe, intercooler.

The flow rate is required to be 110 m h) after entering the secondary compression system.

In order to prevent the gas in the system from pouring into the compression chamber (to avoid starting under pressure), a suspended full-opening check valve is installed in the exhaust pipe of the compressor.

The gas discharged from the compressor pushes open the check valve into the exhaust muffler, enters the primary aftercooler, the secondary aftercooler, and then enters the exhaust main pipe.

The functions of oil-free air compressors and oil-free air compressors are different, and the application places are not the same, as long as you pay attention to the correct use method and regular maintenance, the durability is basically the same. It is recommended to choose Tianshui Jufeng's LGCY-23 27 fixed screw air compressor, which has a lower speed and longer service life under the same effect.

Tianshui Jufeng LGCY-23 27 fixed screw air compressor adopts the design idea of "large rotor, large bearing, low speed", the speed is 30 50% lower than that of other brands, which can reduce noise and vibration, reduce exhaust temperature, improve rotor rigidity, prolong service life, and reduce the sensitivity to impurities and oil carbides. The output of the compressor is connected to the gas tank, and there is a preliminary condensation in the gas tank, so it is often necessary to open the drain valve at the bottom of the gas tank frequently to drain water, or install a timed automatic drain valve to drain water regularly.

Compared with oil-free air compressors, oil-free air compressors are more clean and environmentally friendly to a certain extent, and they occupy an absolute advantage in the fields of food and medical treatment. Because the gas that comes out does not need to do much follow-up treatment to meet the oil-free requirements, but at the same time, the ** of the oil-free air compressor will be more expensive.

The oil-free ones are better, and the oil-free ones are lubricated because the oil is lubricated and also involved in compression, so the oil quality attenuates greatly and is not easy to control. The oil-free one is relatively better, but in terms of cost, the oil-free one is much more expensive!

Everyone knows that the oil-free air compressor uses lubricating oil to lubricate the main engine screw screw, while the oil-free air compressor is lubricated with water or a dry air compressor. So some people may wonder, is the oil-free air compressor more likely to wear and tear and not durable enough?

1.It has the characteristics of an oil-air compressor.

Oil-injected screw air compressor is still a relatively common type of air compressor on the market, because of the role of lubricating oil between the rotor of the main engine, the oil-injected screw air compressor operates with low vibration, low noise, high efficiency, and superior and reliable performance. Moreover, the lubricating oil also has a sealing function, which reduces the possibility of gas leakage in the work of the air compressor and ensures that the machine can produce compressed gas with qualified pressure, but because the air is in direct contact with the lubricating oil during operation, the compressed air directly produced by the oil-injected screw air compressor contains a large amount of oil, which must be purified by post-treatment equipment to meet the use standard.

2.Characteristics of oil-free air compressors.

Oil-free air compressor is just like the literal meaning, the air compressor does not need oil to lubricate during operation, and the process of compressing air will not come into contact with oil, because the biggest feature of oil-free air compressor is that the compressed air produced has a very low oil content, and can even reach 100% oil-free.

3.Whether the oil-free air compressor is durable.

In fact, this problem has been taken into account in the research and development of oil-free air compressors. Although the oil-free air compressor has no oil lubrication, the main screw of the oil-free air compressor will be coated with a special hardening layer, and repeated experiments have proved that as long as the oil-free air compressor is regularly maintained, there is no obvious difference between the durability and service life of the oil-free air compressor and the oil-bearing machine.

I bought an oily one for five years, and it hasn't broken yet, some of the fuel injections are not used, and the oil-free ones are replaced by the oil-free ones, and the Ortus ones have been used for more than a year, and they are broken, and the Fujii ones have been broken for six months, and they have been changed to several brands later, but they have not been used for a year, and my conclusion is that the oil-free ones are too bad!

It's a vacuum pump. There is no conclusion, each has its own advantages and disadvantages, the oil is dirty, and now the oil-free screw pump is generally selected, which is expensive.

If it is used for purging, machining, manufacturing, and power use, the air compressor with oil and oil can be selected, but some occasions must use oil-free air compressors, such as food, medicine, precision instruments and other industries. Oil-free air compressors are more clean and environmentally friendly than oil-based air compressors to some extent, but oil-free air compressors are more expensive than oil-based ones, and the maintenance cost is also higher.

In addition to the best aspects, there are the following differences between oil-free air compressors and oil-based air compressors:

1. The oil content is different, generally the oil content of the oil engine is larger, and the oil content of the oil-free machine is, so this oil content is used to distinguish the air compressor from oil. There is also a completely oil-free air compressor, which is lubricated with resin material, so the final exhaust gas does not contain oil, which is called a completely oil-free air compressor.

2. The structure is different, whether it is an oil-free piston machine or an oil-free screw machine, a large number of high temperatures will be generated during the operation, and the participation of oil in the air compressor will take away the high temperature generated in the compression process of the air compressor, so as to cool down the machinery. The oil-free air compressor uses a special high-temperature resistant material called Teflon or molybdenum disulfide to replace the oil to solve the high temperature in the compression process of the air compressor, so as to achieve the purpose of oil-free compression.

It is better for the air compressor to be oil-free.

Compared with air compressors, oil-free air compressors have the following advantages:

1. Due to the use of small cylinders, the air compressor is light and compact.

2. The balance of the air compressor is good, so there is no need for a foundation.

3. The vibration is slight.

4. The small stroke volume of a single cylinder makes the pulsation of the intake end and the exhaust end less than 1%, and there is no need to install a pulsation elimination device.

5. The noise level is about 70-82 decibels, and no additional measures need to be taken.

6. Easy maintenance, due to the small and lightweight air compressor parts, the customer's own personnel can maintain the compressor.

7. Since the drive system is contactless and maintenance-free, there is no need to use expensive piston rod stuffing box. The compressor is permanently hermetically sealed and completely hermetically sealed.

At the heart of the oil-free air compressor is the superior two-stage compressor unit. The rotor is finished in twenty operations to achieve unmatched precision and durability in the rotor line. It is equipped with high-quality bearings and precision gears to ensure the coaxiality of the rotor, so that the rotor fits accurately, so as to maintain long-term efficient and reliable operation.

Overview of the working principle: oil-free air compressor is a miniature reciprocating piston compressor, the motor single-shaft drive symmetrically distributed crank rocker mechanical structure, the main motion is the piston ring, the auxiliary motion is the aluminum alloy cylindrical surface, and the piston ring is self-lubricating without adding any lubricant. The volume of the cylinder on the cylindrical surface changes periodically through the reciprocating motion of the crank rocker, and the cylinder volume changes twice in the opposite direction during the motor operation.

When the positive direction is the direction of cylinder volume expansion, the cylinder volume is vacuum, the atmospheric pressure is greater than the air pressure in the cylinder, and the air enters the cylinder through the air valve, which is the suction process at this time: when the opposite direction is the direction of volume reduction, the gas entering the cylinder is compressed, and the pressure in the volume increases rapidly, and when it is greater than the atmospheric pressure, the exhaust valve is opened, and it is the exhaust process at this time.

The structural arrangement of single shaft and double cylinder makes the gas flow rate of the compressor twice that of the single cylinder at a certain rated speed, and makes the vibration and noise generated by the single-cylinder compressor be well solved, and the overall structure is more compact.
