According to the industry to choose oil-free air compressor, not only to consider the air compressor, air compression station investment, operating costs, operating costs and other comprehensive technical and economic indicators, but also to consider whether the air compressor in line with environmental protection, stable and reliable, excellent production quality principle. Overall, I have summarized the following points:
1. The air compressor must meet the hard core requirements of the flow value and pressure value required in the production process. The working environment of the air compressor is usually required to be kept within the high energy efficiency range, which can save a lot of unnecessary power supply, and it is not easy to damage the components and cause unnecessary losses.
2. The air compressor you choose must be small in size, light in weight, reasonable in price, high in energy efficiency, and environmentally friendly emissions.
Low noise, stable operation and long service life.
3, simple structure, convenient operation, easy to buy accessories;
4. What is the estimated cost of purchasing the air compressor project for the selected air compressor unit station and whether it is more energy-saving.
Obviously, when choosing an air compressor, it is mainly based on the working pressure and flow rate of the starting system. The working pressure of the air source should be higher than the z large working pressure of the pneumatic system, because this is related to the loss and local loss of the gas pipeline. If the system is running when it is required, the working pressure requirements of some places are low, the pressure reducing valve can be used. The discharge pressure of the air compressor is divided into low pressure, medium pressure, high pressure) and ultra-high pressure or above. You can choose different discharge pressures according to your actual needs. Usually low pressure between 0.7 ~ 1.25Mpa. There are still many demands in the industry, which can be considered as appropriate.
Next, the choice of oil-free air compressor is introduced:
understand the air characteristics, local atmospheric pressure and local air relative humidity will affect the use of air compressors.
2. The diameter and content of solid dust particles in the air are also a point that needs attention, which is related to the use temperature of the later equipment.
3, and the required flow. We are often referred to as air flow. Exhaust volume refers to the air compressor in the specified exhaust pressure per unit time can be discharged gas statistics, and finally reach the amount of intake state.
4. Unit flow rate: m & sup3;/min (m3/min);
5. Considering the large working pressure of z, it depends on the pressure requirements of the air compressor you buy.
In addition, when determining the volume flow of the oil-free air compressor, it is necessary to understand the total volume flow of the gas equipment. Most people do not know how to calculate it. They can consult the selection technicians and make appropriate selection to avoid waste. It is good for users and air compressor equipment.
Is it difficult to choose an air compressor for industrial use? Among the large air compressors, the "water-lubricated air compressor" produced by Shanghai Granklin Group can achieve 250KW power on a single machine. Industrial use of oil free air compressor choose it:
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 detailsScrew air compressor sometimes work for a long time, resulting in the phenomenon of high temperature, especially in the summer, when the temperature is too high fault often occurs, then the air compressor temperature is too high is how to return a responsibility? 1. Poor environmental ventilation and heat dissipation There are three main situations in which the surrounding environment of the air compressor affects heat dissipation: first, it is too close to wall-like obstacles; Second, there are other heat sources near the air compressor; third, the front door and side doors of the air compressor are open during operation, and the fan cannot form strong airflow.
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
Shanghai granklin group water lubrication air compressor manufacturer, as a member of the air compressor industry, we talk about other types of air compressors, such as dry oil-free air compressors. Dry oil-free air compressor its product advantages are:
Minor maintenance only needs to replace the air compressor oil and oil filter, which is usually replaced after 500 hours of operation of the new machine. Major maintenance is carried out about 3000 hours of operation of the machine, and the air filter element of the air compressor, oil and gas separator core, motor grease, etc. Electric shift
Power frequency, frequency conversion, permanent magnet variable frequency air compressor difference? Power frequency air compressor, motor constant speed operation, if the gas is not very big, the more power frequency air compressor power consumption, start the impact on the power grid will be very large. Frequency conversion air compressor, installed
View detailsThose engaged in the installation, transformation and maintenance of pipelines such as gas storage tanks and other pressure vessel equipment must obtain the corresponding qualification license. Units engaged in installation must have installation qualifications, install in accordance with relevant safety specifications and requirements, and be responsible for the safety and quality of pressure vessels, and strictly implement national safety standards and technical standards.
The water-lubricated air compressor produced by Granklin Group has its own patented technology for the head of the air compressor. The 100% oil-free compressed gas is used in a wider range and is more suitable for scenes with special needs for gas. Aircraft manufacturing: spray washing machine, die withdrawal, drive assembly tools, drilling machines, steam hammers, hoisting hoists, combined tools, reamers, riveting guns, screwdrivers, forging hammers, metal forming presses, sandblasting, painting. Automobile manufacturing: spray washing machine, drive
For the screw air compressor should be how to select, you first need to know the work flow of the screw air compressor, and then determine how to select. Generally speaking, there are three steps:(1) first determine the working pressure;(2) then set the corresponding volume flow;(3) finally, the power supply capacity. Selection of working pressure (exhaust pressure):
