In the textile industry, air-jet looms require dry and oil-free compressed air. In the production process, the thin nozzle blows compressed air onto the wire harness to form a vortex, which gives the yarn shape, elasticity and elasticity from the surface. The pure compressed air provided by the oil-free air compressor can ensure the quality of the finished fabric.
At the same time, the air-jet loom also requires the quality of compressed air:
(1) Requirements for moisture
the moisture of the compressed air for weft insertion of the air jet loom should not be too high, otherwise the moisture will precipitate in the compressed air pipe and condense into water droplets, causing the pipe wall to stick to dust, increasing the pressure loss along the pipe, and generating water droplets at the opening and closing of the nozzle., Affect the quality of the jet, and cause corrosion of the reed and nozzle loom parts. Therefore, the pressure dew point of compressed air should be set above 4 ℃.
(2) Requirements for oil content
this is what everyone can intuitively perceive. The oil particles in the compressed air will pollute the fabric, produce defective products, and adhere to the nozzle outlet, which will affect the spray force and trajectory of the nozzle, reduce the weft insertion effect, and make the weft insertion disgusting. The adhesion of oil particles on the reed will increase defects, and the diffusion of oil particles produced by production vehicles in the air will pollute the environment and endanger the health of workers. Therefore, oil particles with a diameter greater than 0.01 microns should be filtered, and the large oil content should not exceed 0.01 mg/m3.
(3) Requirements for dust and toner
because the meshing gap of the air compressor is very small, the dust and carbon powder contained in the air will accelerate the wear of the compressor and reduce the service life of the screw. Impurities, dust and toner above 1 micron should be ***, and the concentration of *** large dust in the air should not exceed 1 mg/m3. Among the three main influencing factors, the oil content of the air is very important for the selection and operating cost of the air compressor model.
When the screw air compressor is in normal operation, it is necessary to know some precautions when using the screw air compressor. This can not only ensure that the normal operation of the oil-free air compressor is not prevented, but also avoid the oil-free air compressor. Unexpected situation. The rest is the need to clean the cooler frequently and discharge the condensed water. Ensure the normal operation of the oil-free air compressor within the specified voltage, frequency and rated load value; Under no circumstances can it be used to pump flammable and explosive gases or operate in an environment containing these gases. Do not use to aspirate liquids, particles, solids and any substance containing explosive, flammable.
Oil-free compressor test machine parameters, screw air compressor test contains what are the main parameters? Especially in the sale of air compressor manufacturers will test the parameters.
View detailsThe main function of energy-saving variable frequency air compressor is to provide compressed air for all kinds of industrial systems. Obviously, as industrial equipment, it can only be trusted by everyone with good performance, and a good energy-saving variable frequency air compressor is also proved in actual use. It is able to adapt to all kinds of high-demand industrial operations.
Water-lubricated air compressor is the main product of Shanghai granklin group. the head of water-lubricated air compressor can be used in permanent magnet variable frequency air compressor, screw air compressor, water-lubricated air compressor and oil-free air compressor. the products are the best in the domestic industry in the field of energy-saving and oil-free air. The energy efficiency grade of air compressor is divided into three levels, the first level of energy efficiency reaches the advanced level, energy saving, the second level of energy efficiency is more energy-saving, and the third level of energy efficiency is high energy consumption, which is the market access index.
View detailsPurchase oil-free air compressor to choose the brand, we are as far as possible to choose the best brand in China, the product quality and after-sales service ability of large factories are impeccable. In the domestic procurement of oil-free air compressors, you can consult the "Shanghai granklin group". water-lubricated oil-free air compressors are currently the mainstream oil-free air compressors in China. as a brand, granklin also has many application cases to visit, basically covering the whole industry.
View detailsMedical air compressor, the requirements are very strict, of course, is to choose stable quality, reliable equipment. At present, domestic oil-free air compressor can consider Granklin air compressor, and it is certainly not wrong to choose a big brand. Granklin air compressor has a great scope of application, meeting different industries
Kunshan oil-free air compressor sales telephone, maintenance of air compressor needs to be familiar with various technologies and skills of air compressor maintenance! The professional oil-free air compressor maintenance master serves the whole Kunshan area and solves the problem of air compressor failure for Kunshan factory. Air compressor in the maintenance need to understand the maintenance knowledge:
The water lubricated air compressor produced by granklin group has a pressure range of 0.15-4Mpa. the exhaust flow rate is determined by the amount of air used to purchase the most appropriate number of machines. When installing the water-lubricated air compressor, the best configuration is to use stainless steel gas storage tanks, pipes, filters, etc.
View detailsIn the field of oil-free air compressor, there is also an air compressor called water-lubricated oil-free air compressor, water-lubricated oil-free screw air compressor, which uses pure water lubrication that meets the drinking water standard, and the entire compression process is completely free of oil participation. Therefore, what is provided is 100% oil-free
Choose air compressor according to the needs of different industries and working conditions, there are corresponding standards. Then how to choose a suitable oil-free air compressor? 1. First figure out what is an oil-free air compressor and why should it be used? The oil-free air compressor has been running
From the oil content point of view, the oil and no oil in the air compressor generally refers to the amount of oil in the exhaust port of the air compressor. There is also a completely oil-free air compressor, which is not lubricated by oil, but by water, so the final discharged gas does not contain oil.
