What are the advantages of screw air compressor than piston air compressor? How does air compressor work?
Air compressor is also called air compressor. It is a device used to provide kinetic energy after compressing air. The compressor is directly driven by a motor or diesel engine. After inhaling air, the air is compressed to a certain value in the air storage tank, causing the cylinder volume to change., Thereby generating pneumatic energy.
There are many types of air compressor, common screw air compressor and piston air compressor.
the piston air compressor uses an electric motor or diesel engine to drive the pulley to directly drive the crankshaft through the coupling, drive the connecting rod and the piston rod, and make the piston reciprocate in the cylinder to complete the suction, compression and discharge process.
When the reciprocating piston in the cylinder moves up and down, the pressure in the left cavity of the piston in the cylinder is lower than the normal atmospheric pressure, the suction valve opens, and the outside air flows into the cylinder. This process is called the compression process. When the pressure in the cylinder is higher than the air pressure in the gas pipeline, the exhaust valve opens and compressed air is delivered into the exhaust pipeline. This process is called the exhaust process.
What are the daily contents of air compressor maintenance?
1. The air compressor manufacturer introduced that the air filter is a component that filters out air dust and dirt, and the filtered clean air enters the screw rotor compression cavity for compression. Because the internal clearance of the screw machine only allows particles within 15u to be filtered out.
2. If the air filter element is blocked and damaged, a large amount of particles larger than 15u will enter the screw machine to circulate, which will not only greatly shorten the service life of the oil filter element and the oil fine separation core, but also cause a large amount of particles to directly enter the bearing cavity, accelerate bearing wear and increase the rotor gap., The compression efficiency is reduced, and even the rotor is boring and seized.
3. The quality of screw oil has a decisive influence on the performance of oil injection screw machine. Good oil has good stability, rapid separation, good foam cleaning, high viscosity and good anti-corrosion performance. Therefore, users must use pure screw oil.

Comparison of Screw Air Compressor and Piston Air Compressor Function
(I), force balance
single-screw compressor: The radial and axial gas forces borne by the screw can be automatically balanced, and the star gear teeth are required to have sufficient strength and rigidity. Twin-screw compressor: The screw rotor bears a large radial and axial gas force, and the screw is required to have sufficient strength and rigidity.
(II), manufacturing costs
single screw compressor: ordinary bearings can be used for screw and star wheel bearings, and the manufacturing cost is low. Twin screw compressor: due to the two screw rotor load is relatively large, requires the selection of high precision bearings, high manufacturing costs.
Although the procurement cost of single screw air compressor is relatively low, the friction between the star wheel and the rotor is more serious, and the star wheel needs to be replaced. The maintenance cost and operating cost will naturally be very high, otherwise the exhaust volume loss will not meet the requirements. Although the temporary purchase cost of the twin-screw air compressor is on the high side, it has extremely high mechanical reliability, stable operation, and strong applicability, so that the later maintenance cost is very low, the failure rate is low, and it will not affect production.
The analysis of the advantages and disadvantages of screw air compressor and piston air compressor is one of the core work of engineering management. It plays a very important role in the management of engineering projects. We must apply the scientific method to the analysis.
There are many air compressor brands on the market. Many customers really don't know how to choose a suitable air compressor. In fact, choosing an air compressor is nothing more than the brand of the air compressor. The price of the air compressor is the most important thing. The stability of the air compressor. There is after-sales service
Granklin water-lubricated air compressor has obtained a number of certifications to ensure that the gas provided is 100% oil-free, and the compressed air provided to users to meet the needs of users for high-quality air sources. If there is no local after-sales service center or entrusted distributor, you can directly contact the head office for warranty service.
Buy products preferred big brand, good service quality manufacturers. From foreign to domestic, there are only a few enterprises that can make water-lubricated air compressors in the screw air compressor industry. "Shanghai granklin Group" is one of them. granklin Do not forget your initiative mind strove forward on the road of water-lubricated air compressors.
Air compressor energy saving characteristics, so that it is widely used in various industries, textile, workshop, factory, medical and so on have the use of screw air compressor. However, after most people bought screw air compressors, they found that they could not reach the energy-saving efficiency mentioned by the air compressor manufacturers, resulting in energy-saving costs.
No oil is used in the compression chamber. Oil does not come into contact with compressed air, but does not remove the oil vapors contained in the atmosphere. This makes the compressed air still contain a small amount of oil impurities. After measurement, the oil content in the compressed air produced by the oil-free air compressor and the area where it is located
For customers who need to save electricity and energy consumption, how to spend less money to buy a good quality oil-free permanent magnet air compressor and reduce the energy consumption expenditure of enterprises is the concern of users. So how much does it cost to buy an air compressor?
The rear end of the air compressor is generally equipped with a gas storage tank. There is a drain valve at the bottom of the gas storage tank. Just open the drain valve every morning before starting the machine. 1. The air compressor will have a drain valve at the lowest part of the cooler; 2. After the air compressor is exhausted, a cold dryer or dry
It is best to use the original lubricating oil or the lubricating oil recommended and specified by the manufacturer. One is the oxidation resistance and thermal stability of compressor oil. For compressor oil, its oxidation resistance and thermal decomposition resistance can not only prevent oil thickening, deposition and sludge formation, but also extend the service life of compressor oil, thereby saving the high cost caused by replacement, shutdown and oil cleaning;
As we all know, there are many types of air compressors, one of which is called permanent magnet variable frequency air compressor, which is also the highest sales volume in the selection of air compressors, and the number of "fans" is also very large, so let's learn about the advantages and disadvantages of this permanent magnet variable frequency air compressor.
If you determine the size and type of compressor, but there is a problem is the choice of oil lubrication or oil-free air compressor. Your choice on this issue should be based on the compressed air application process. Do I need an oil-free compressor? Choose
