screw air compressor:
there is a pair of rotors inside the screw air compressor, and they are toothed with each other. The working cycle can be divided into three processes, namely suction, compression and exhaust. As the rotor continues to rotate, the intermeshing teeth complete the same duty cycle.
scroll air compressor:
the internal structure of the scroll air compressor is mainly composed of a fixed scroll body and a winding scroll body. There is a sealing line between the two scroll bodies, forming a crescent-shaped air cavity. However, the sealing line will also change, so the shape of the air cavity will also change and will not remain the same all the time. The air compressor shell has an air suction port and is fixed. During operation, the gas enters from the air suction port and then enters the crescent-shaped air cavity. After the air cavity is slowly closed, the air cavity and the suction port are blocked, the gas is slowly compressed, the pressure is slowly increased, and the volume is slowly reduced.
The difference between screw air compressor and scroll air compressor is as follows:
1, the working principle is different
the working principle of the scroll air compressor: The main components of the compressor are two involute scroll coils with the same shape but the angular phase positions are relatively staggered by 180 °. One is a fixed coil, and the other is driven by an eccentric shaft., The axis revolves around the axis of the fixed coil. In operation, the two coils are cut in multiple directions to form a sealing line, and the two coils are properly sealed at the end faces to form several crescent-shaped air cavities.
Screw air compressor principle: screw air compressor cylinder is equipped with a pair of intermeshing spiral male and female rotor, two rotor has several concave teeth, the two reverse rotation of each other. The working cycle can be divided into three processes: suction, compression and exhaust. As the rotor rotates, each pair of intermeshing teeth successively completes the same duty cycle.
2. Different working conditions
scroll compressors have the characteristics of small torque changes, high balance, low vibration, stable operation, simple operation, easy realization of automation, and low noise. They are mostly used under air-conditioning conditions.
The screw air compressor has high operability, good power balance and strong adaptability, and is suitable for various working conditions.
Advantages of screw air compressor
1. Screw compressors are the same as piston compressors and belong to positive displacement compressors. On the use of the effect to see the screw air compressor has the following advantages.
2. High reliability. Screw compressor parts less, no wearing parts, so it is reliable operation, long life, overhaul interval of up to 4-80000 hours.
3. Convenient operation and maintenance. The screw compressor has a high degree of automation, and the operator does not have to go through a long period of training, and can realize unattended operation.
Common types of oil-free compressor are: oil-free scroll air compressor, dry oil-free air compressor, water lubrication oil-free air compressor. Different oil-free screw air compressor models, exhaust pressure, power and exhaust volume parameters are different. The medical water-lubricated air compressor produced by Shanghai Granklin Group is 100% oil-free.
View detailsWhether the "water-lubricated oil-free air compressor" can really be 100% oil-free? This question has doubts in the minds of users who have not used it, which is normal. It is a good thing that people have doubts about the unknown "water-lubricated oil-free air compressor". However, there are still a large number of users who have already purchased "water-lubricated oil-free air compressor". As the first crab eater, they have already used the "water-lubricated oil-free air compressor" of "Shanghai granklin Group" to carry out safe and high-quality gas production.
Screw air compressors are more common in the air compressor market, gradually replacing piston machines. Basically the piston machine has been taken off the market. But how do you know the price of an air compressor? Users who do not understand must bear the burden.
When it comes to medicine, everyone should be familiar with it. However, most people are not very clear about the production process of drugs. Screw air compressors are often used in the production of drugs. So what role does the air compressor play in the pharmaceutical industry?
For ordinary production industries, the requirements for air compressors are not very strict. At this time, you can choose an air compressor with oil or micro-oil. After all, the cost of an air compressor with oil or micro-oil is different. And for some of the air compressor requirements are more stringent enterprises, such as laser cutting, medical and other industries, will be more stringent requirements on the air compressor, the need for air compressor can reach the standard of oil-free. This time to choose an oil-free air compressor.
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
How much does it cost to maintain an air compressor? There are many things to refer to for the cost of one maintenance. For example, according to the degree of maintenance, air compressor maintenance itself can be divided into large maintenance, small maintenance and medium maintenance. And different air compressor brands,
Such as biology, medicine, electronics, food, medical, automotive, chemical and other fields, water, oil, dust, bacteria, etc. are required to reach a higher level, but the water, dust, bacteria in the compressed air can be solved by a series of post-processing equipment such as filters and dryers, and
The water lubricated air compressor produced by granklin group does not contain oil. it only needs to replace the air filter element and water filter element regularly according to the manufacturer's requirements and maintain the head of the water lubricated air compressor. Oil and no oil in the air compressor generally refers to the amount of oil content in the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the oil machine is relatively large, and the oil content of the oil-free oil machine is 0.01ppm. Therefore, the oil content is used to distinguish the oil and no oil in the air compressor.
View detailsWhat are the safety measures in the work of the air compressor?(1) When the compressed air is cooled, the oil-water mixture condensed in the cooler, air storage barrel and oil separator must be blown off in time, at least once per hour. (2) When the air compressor is working, if the cooling water supply is not timely, it must be parked immediately to be cooled.
