(1) Fully meet the gas consumption needs of gas-using equipment
the maximum gas consumption shall be calculated according to the type and quantity of pneumatic equipment, and the gas consumption that may be increased in the future shall be included, and then the air compressor equipment that can meet the gas supply requirements of pneumatic equipment shall be selected. To be on the safe side, the gas supply capacity of the air compressor shall exceed the demand (at least 25% surplus shall be produced). When calculating the compressor output, the actual gas output of the compressor shall prevail, the theoretical calculation of gas production should not only be considered. Under the pressure of 689.5kPa, the actual gas production can be deduced by empirical formula, I .e. the gas production per horsepower (1 horsepower-0.746kW, the same below) of electric motor is 0.13 m3/min, and the gas production per horsepower of pneumatic motor is 0.057 m3/min. At the same time, the actual gas production is reduced due to the increase of altitude and the increase of ambient temperature, and the high moisture and humidity in the air will also reduce the gas production capacity of the compressor. The gas consumption of various pneumatic equipment is shown in Table 4-4.
(2) Maximum pressure required for pneumatic equipment
based on this, it can be determined to use a single-acting, double-acting or multi-acting air compressor.
(3) Select according to construction requirements
small construction optional diaphragm compressor, general construction often choose reciprocating air compressor. It is best to prepare two air compressors, one with high power for full-load all-day work and the other for half-day or non-full-load use, so that the gas requirements of the system can be met in different situations. A standby compressor is on standby, even if another compressor is damaged, it will not affect the work. The two compressors are regularly rotated in a week cycle, which is conducive to maintaining good working conditions for both compressors.
(4) Select the control mode according to the construction characteristics
if the gas is used continuously and stably, the air compressor with constant speed control device should be selected. If the gas is used intermittently, the air compressor with automatic opening/closing control device should be selected. If the gas is used intermittently and sometimes continuously, the air compressor with dual control device, I .e. both automatic opening/closing control device and constant speed control device, needs to be used.
Shanghai Granklin Group produces water-lubricated air compressors. Water-lubricated air compressors do not use lubricating oil. Water is used as a lubricant with less pollution, better environmental protection and cleaner exhaust gas. Today's society promotes environmentally friendly travel. If the distance to work is not too far, more and more people choose to walk and ride bicycles as their main mode of travel. Environmental protection is the eternal theme of life. A high-quality environmental protection air compressor will bring convenience and quickness to your work.
View detailsAir compressor type variety, wide range of uses, and different types of air compressor, the lubrication requirements vary greatly. In the air compressor parts, the lubricating oil plays a role in preventing wear, sealing, and cooling, minimizing the influence of air on the viscosity of the lubricating oil and the reaction between additives and air, so as
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.
Air compressor is the abbreviation of "air compressor. As early as 1640 AD, the first (mechanical) vacuum pump made in Germany, now, with the improvement of technology, air compressors have been busy in all walks of life, such as food, tobacco and other metallurgy, petrochemical, chemical fiber, pharmaceutical and so on.
What is the difference between a fixed screw air compressor and a variable frequency screw air compressor? Most of the variable frequency air compressors are also fixed, and the fixed screw air compressors include variable frequency air compressors and water lubricated air compressors produced by Grantklin Group are also fixed.
View detailsThe traditional "oil-injected screw air compressor" in the development of "water-lubricated oil-free air compressor", the impact is not small, users due to the upgrading of enterprise product lines, more inclined to use "water-lubricated air compressor", or similar "oil-free air compressor". The construction of a civilized city proposed by the state has higher and higher environmental protection requirements, and the products invested in "water-lubricated air compressors" have also been highly recognized by the market.
Application industries of water-lubricated air compressor produced by Shanghai Granklin Group: university laboratory, chromatographic analysis, medical pharmacy, dentistry, food processing, construction engineering, chemical industry, machinery, environmental protection, meteorology, hydropower, spraying, sandblasting, PET bottle blowing, leak detection, metallurgy, water treatment, printing, shipping, textile, petrochemical, electronics
View detailsSpraying processes can be seen everywhere in life, such as the surface of car bodies, hardware and plastic products, etc. The main function is to prevent corrosion. Oil-free screw air compressor is often used to do power source in the spraying process. So does the spraying industry have any need for air compressors?
The compression types of air compressors can be divided into three types: if there is a dryer in the air compressor room, the air storage tank must be installed before the dryer, so that the compressed air discharged from the air compressor can be properly buffered before entering the dryer And cooling, the dryer needs to have
The water lubricated oil-free air compressor uses pure water lubrication that meets the drinking water standard, and the entire compression process is completely free of oil. Therefore, the water-lubricated air compressor provides 100 percent oil-free clean compressed air. Product features: 1, high efficiency, reliability
