What is the most important compressor components?
The basis of common compressors is that by reducing the volume of the incoming fluid, they increase its pressure. Of course, recently and according to the advancement of technology, a type of compressor has been made that compresses the air using centrifugal force or compression force of a piston. As mentioned, compressors have many uses, which are briefly reviewed below:
Tire inflation
Refrigerators
chiller
Pipelines
Cooling systems
Refrigeration systems
Jet engines
wind songs
Compressors have two general categories: dynamic and positive displacement, each of which works differently. Compressors are very versatile, for example:
Centrifugal compressor
Axial compressor
Piston compressor
Diaphragm compressor
Spiral compressor
Gear compressor
Scroll compressor
Vane compressor
Introducing Wind Compressor Parts
Wind compressor is one of the types of compressors that may have any mechanism. These compressors have both industrial use and home use and are available in various sizes. Like the small portable home compressors that work with hand power or its semi-industrial type that is used in building and car painting or in apartments.
motor
This member is one of the most important parts of the air compressor because it provides the necessary force to compress the air, and in other words, they are the beating heart of this set. These engines are available in two types, diesel and electric, and by receiving the energy in the fuel they receive, they provide the necessary mechanical power. In wind compressors, after electric motors, internal combustion engines are used more. The structure of these engines is similar to car engines and there is only a difference in their size and power.
coupling
This member is used to transmit power between the pump and motor shaft screws. The reason for using couplings in air compressors is the flexibility property that is obtained from changing the length of the material between the screws and makes it coaxial. These couplings are installed on the pump and motor shafts and their edges are serrated. These teeth are covered by a bush (one-piece or two-piece) that has internal teeth, and the teeth of the gears engage with the internal teeth of the bush, and the torque is transferred from the motor to the shaft. The method of connecting these two bushings is varied and for example, it can be done by using a spacer.
piston
Like a car engine, the piston is the moving part inside the cylinder, which causes movement in another part called the connecting rod. These pistons go up and down using the explosive power of the fuel and become the engine movement. In compressors, power is transferred from the crankshaft to the piston, which are generally made of aluminum alloy, and it is the first part of the engine that starts to move and produces mechanical energy.
piston rims
This member of the air compressor parts has three subsets of pressure ring, oil ring and seal ring, each of which has a task:
Pressure ring: This part is used to prevent the penetration of compressed gas into the crankcase.
Oil rim: Oil rims are used to prevent oil from escaping.
Sealing ring: These rings are used to prevent liquids from entering and exiting the piston.
The important thing to mention about the rims is that they should stick as much as possible and be the same size as the groove, and at the same time, they should not hinder the free movement of the piston in the cylinder.
Sure Valve
A safety valve is a small piece of air compressor parts that is generally installed in the cylinder head, and its job is to regulate the amount of air and fuel entering the cylinder and creating a space for smoke to escape from the cylinder. This member is one of the most vulnerable members of the wind compressor engine.
suction valves and propulsion compressor
which are used to control the incoming and outgoing air.
compressor gearbox gear
This member is mostly for screw compressors and has a hard and resistant sex. Its job is to transfer power.
compressor filtration
Filtration of air compressor from the parts of air compressor, it has three separate sub-assemblies, each of which is working in one part.
oil filter
air filter
Separator filter
Oil Filter
Compressor oil filter that cleans the oil circulating around the engine so that the operation of the cylinders and pistons is not challenged.
Air Filter
The air filter, which is another part of the air compressor, is used to purify the air and prevent the entry of small particles in the air into the combustion chamber.
Filter Separator
These types of filters are designed and manufactured to separate solid or liquid particles from the gas flow. This part is generally installed at the beginning of the work process of compressors on the inlet air path and at the end at the beginning of the output path.
Thermal Sensor
It was said that the air compressor is responsible for changing the gas pressure and compressing it. This change in pressure is associated with the change in gas temperature, and for this reason, a sensor has been installed in the outlet of the compressed gas to warn if the temperature of the outlet gas is high and prevent danger.
After the cooler
It was said that by compressing the gas, its temperature rises and there is no escaping this issue. To solve this issue, in places where the temperature of the compressed gas output is important for us, a cooling system called after cooler is used on the way of the output gas.
Inter cooler
According to the amount of air compression needed in different parts of life, some devices use several stages to bring the gas to the desired pressure. During this multi-stage process, sometimes the temperature reaches a dangerous level, to prevent this from happening, a cooling system is installed in the air compressor parts before one or each stage of pressure change, which is known as an intercooler or internal cooler.
Compressor Pressure Sensor
The work of compressors is a change in gas pressure, that's why they have a sensor to prevent overcompression of gas or less than the required amount when they do the compression process. This member is known by other names such as pressure transmitter, pressure transducers, pressure indicator, pressure transmitter, pyrometer and manometer.
radiator
An inseparable part of internal combustion systems are radiators, which keep the temperature of the engine body and its parts in ideal conditions by circulating the coolant around the engine.
heat exchanger
Generally, heat exchangers are used to increase reliability and reduce energy consumption. For example, an alloy is used in the engine body that easily loses its heat and does not have high resistance.
It should be noted that some of the above parts are accessories and your air compressor can be without them and continue its operation without any defects. Here are the more commonly used parts that may fail.
