Common types of air compressor hosts mainly include the following:
scroll type air compressor:
working principle: Through the meshing of the fixed scroll and the movable scroll, a plurality of compression chambers are formed, and two staggered spiral blades are used to compress the air, so as to realize the suction and compression of the gas.
Features: simple structure, small footprint, low noise, long service life, but high sealing requirements.
Screw air compressor (including twin screw type):
working principle: Mainly rely on the rotation of the rotor and the increase of the cogging volume to inhale. The gas is pressed into the exhaust end through the mutual meshing of the male and female rotors, and finally discharged through the exhaust port.
Features: It has the advantages of high reliability, simple structure and high efficiency.
Shanghai Granklin Group's "water-lubricated screw air compressor" has the characteristics of high gas cleanliness and water-lubricated air compressor head.
piston type air compressor:
working principle: The air is compressed by the reciprocating piston to obtain high-pressure air.
Application: Pneumatic tools commonly used in small machines, workshops and vehicles, such as nail guns, paint spray guns and stamping machines.
Features: small size and low price, so it is widely used in small equipment and machines.
centrifugal air compressor:
application: Mainly used in occasions that require high flow, such as water treatment, power and chemical industries.
Features: high efficiency, low noise, high reliability, and can provide high pressure and high flow of air.
membrane type air compressor:
application: Mainly used in the medical and pharmaceutical fields, because it can provide dry and clean air, and will not produce oil and dust.
Features: It can filter and separate impurities in the gas to ensure the purity of the air; because there is no lubricating oil and piston, it is very suitable for applications with high purity requirements.
In summary, different types of air compressors have their own characteristics and advantages according to their working principles and application scenarios. When choosing an air compressor, it is necessary to make a decision according to the specific needs and working environment.
The purity of compressed air can usually reach between 99.2 and 99.99 percent, depending on the type of air compressor, subsequent purification measures and the application scenario. The following are the key factors affecting the purity of compressed air and specific instructions: 1. core factors
If the air compressor is an oil-free screw machine, there is no need to consider the pressure vessel inside the machine, because it does not have an oil and gas separation cylinder. If it is a fuel injection screw machine, the oil and gas separation cylinder inside belongs to the pressure vessel. Generally, it is necessary to handle the notice of commencement and the inspection of the pot.
Air compressors are used to compress gas. The compressor is similar in construction to a water pump. Most air compressors are reciprocating piston type, rotating blades or rotating screws, and their noise control mainly adopts three aspects: muffler, muffler tunnel and sound insulation technology.
The air compressor room of the pharmaceutical factory plays a vital role in the pharmaceutical process, and its main role is reflected in the following aspects: 1. Provide pure compressed air The pharmaceutical factory has extremely high requirements for the purity of the production environment. The air compressor room removes the moisture in the compressed air
There are two main cooling methods for screw air compressors: water cooling: the water cooling method uses the fluidity and temperature difference of the cooling water to keep the temperature of the air compressor equipment within a suitable range. In this way, the cooling water passes through the shell-and-tube (or tubular) cooler, and the high temperature
When the day's work is coming to an end, our air compressor and dryer also need to rest. So, how to let them sleep safely? This requires us to follow a gentle and considerate shutdown sequence to operate. First of all, we have to first air pressure
The production of water-lubricated screw machines is really a precise and interesting process. Imagine that workers are carefully assembling each part of the machine, like building a complex Lego model. Each part must be accurately placed to ensure that the machine
Cold dryer exhaust high temperature alarm may be caused by a variety of reasons, the following are some possible reasons and the corresponding solutions: equipment failure: condenser blockage or cleaning is not complete: this will cause the heat can not be normal, and then trigger the high temperature alarm. Should be fixed
In the compressed air system, the refrigerated dryer is the key equipment to ensure the gas quality and stable operation of the equipment. Its core function is to remove moisture from compressed air through cooling technology to avoid negative effects of moisture on production equipment, processes and product quality.
When evaluating the performance of an air compressor, the power size is not the only or decisive factor to measure its merits, so it cannot be simply considered that "the greater the power of the air compressor, the better". The power of the air compressor refers to the work done in unit time, which reflects the air pressure.
