What are the advantages and disadvantages of screw air compressor compared to other types?
The advantages are:
(1) Product specifications are relatively easy. In a certain air volume range, the diameter and shape of the rotor can be maintained unchanged, and only the screw rotor needs to be lengthened and shortened to meet the needs of different air volumes. This feature can reduce manufacturing costs to help market Competitiveness.
(2) The same as the reciprocating air compressor has the common characteristics of the fixed displacement air compressor, and the 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 the advantages of easy maintenance.
(4) The noise level of the screw air compressor can almost be said to be in the air compressor. The noise level depends on the air volume and is often more than 100dbA. Therefore, the screw air compressor must be equipped with a sound insulation cover, which also gives people a good impression of more beautiful appearance.
(5) Throttling control can be used.
(6) The shaft seal of the oil-injected screw air compressor has good air tightness, while the shaft seal of the centrifugal compressor used for high speed cannot be achieved, so it is not suitable for any gas compression other than air or nitrogen.
(7) [Water-lubricated air compressor] As the main product of Shanghai Granklin Group, it has achieved "100% oil-free compressed gas" in the field of oil-free compressed air"
disadvantages are:
(1) The gap that must exist between the yin and yang screws results in unsatisfactory air tightness, which is the main reason for the poor energy efficiency of the oil-free screw air compressor, and it can even be said that it is the same volume of various types of air pressure. The oil-injected screw air compressor solves this problem, but the pressure loss caused by its oil filter element increases a certain proportion of energy consumption.
(2) The oil-free screw compressor body has a life span of only 3-5 years, and the technology of replacing and repairing the air compressor body is often retained by the original manufacturer. Therefore, the cost of replacing the whole set of air compressor bodies will generally exceed 60% of the purchase of new machines, which is also the criticism of users for making this type of air compressor bigger.
(3) The oil-injected screw air compressor stops for a long time after long-term operation. It is not uncommon for the rotor in the air compressor to be stuck (mainly due to the precipitation of grease in the lubricating oil), and the standby air compressor becomes an extremely unreliable standby state.
(4) The compressed air of the oil-injected screw air compressor contains oil, which is not suitable for the food industry.
(5) The oil-injected screw air compressor has high requirements on the quality of lubricating oil, and requires regular maintenance such as lubricating oil replacement and filter element replacement, and the maintenance cost is high
This reason is more, we first one to rule out, first of all, we have to understand how much your air compressor flow, and your gas is proportional to, if the screw air compressor itself flow is not up to, what do you think is the problem,
Air compressor oil, can't 1. Don't change the oil indiscriminately. The air compressor has special oil. If you change other oil, you can't do it at all. 2. Maintenance, that is, changing the oil and filter. The air filter can be taken out and blown to continue using. If it is deformed, it needs more
Purchasing air compressors in Taiwan, especially screw air compressors, can choose Shanghai Granklin Group in mainland China. A focus on water-lubricated air compressor enterprises, products to achieve oil-free, stable gas supply, in the domestic air compressor industry belongs to the high-end industry.
View detailsOn the whole, it is more cost-effective to purchase water-lubricated air compressors. After all, water-lubricated air compressors are better than traditional oil-injected air compressors in terms of maintenance and gas.
In recent years, the voice of energy saving and emission reduction in China is getting higher and higher, and the demand for energy-saving equipment is also increasing. Increasing energy conservation has also become a realistic task facing the air compressor industry. Variable frequency air compressor is a kind of energy saving air compressor
Good or bad depends on the occasion of use and the actual working conditions. In some cases, such as food, medicine, precision instruments and other industries, it is necessary to use a full oil-free air compressor. But the whole oil-free air compressor is much more expensive and the maintenance cost is higher. If it is used to blow
Manufacturers who need compressors often cannot tell the difference between oil-free screw air compressors and oil-free scroll air compressors. In fact, there are many similarities and differences between screw machine and scroll machine. The following granklin water lubricated air compressor manufacturers compare and distinguish through working principle, detailed comparison data, advantages and application scenarios.
View detailsAir compressor according to whether the gas contains oil, to choose the purchase of oil-free air compressor or oil-free air compressor. In the air compressor, the selected lubrication method and lubricating material will be closely related to the composition and nature of the compressed medium. Oxygen in the oxygen air compressor will cause the mineral lubricating oil to oxidize violently and cause the air compressor to burn or explode, so oil lubrication should be avoided.
View detailsIn the post-processing equipment of the screw air compressor, there are mainly air storage tanks, dryers and filters. Dry compressed air can ensure the operation of air compressor air system and production process. The role of the dryer is to eliminate the condensed water in the compressed air and ensure the discharge of dry and clean compressed air. In the equipped with the relevant dry
As we all know, the screw air compressor adopts a pre-set configuration, only a single power connection and compressed air connection, and built-in cooling system, which can greatly simplify the installation work. Its advantage lies in the use of high-capacity compression components, its rotor outer circle speed is low, to achieve a high
