The available materials for screw air compressor supply pipelines are roughly divided into pressure hoses (suitable for small screw air compressors or temporary gas use), galvanized pipes, moderate prices, widely used in the installation of screw air compressor pressure pipelines, aluminum alloy super pipes, suitable for customers with high requirements on factory image, gas supply quality, gas supply stability, etc. At present, the price of aluminum alloy super pipes is slightly higher than that of galvanized pipes, but with the increase of customer demand, the reduction of material prices, the convenience of installation of aluminum alloy super pipes, the guarantee of compressed air quality, and the reduction of compressed air loss have determined the future trend of the market.
Screw air compressor pipeline installation needs to meet the following 10 requirements:
1. The air supply port of the screw air compressor unit needs to install a stop valve, and the pipeline must have a slope of 1 ° -2 ° to facilitate the discharge of condensed water in the pipeline.
2. The pressure drop of the piping shall not exceed 5% set by the screw air compressor, so it is best to choose a pipe diameter larger than the design value when piping.
3. The branch pipeline must be connected from the top of the main pipeline to prevent the condensed water in the pipeline from flowing down to the working machine or back to the screw air compressor group.
4. Tools to be lubricated should be equipped with a triple combination (air filter, pressure regulator, oil feeder) to maintain the service life of the tools.
5, the main pipe can not be arbitrarily reduced, if it is necessary to reduce or enlarge the use of reducing pipe, otherwise there will be mixed flow at the joint, will lead to a great pressure loss, at the same time also has a great impact on the life of the pipeline.
6. If there are purification buffer equipment such as air storage tank and dryer after the air compressor, the ideal piping should be air compressor + air storage tank + dryer. In this way, the gas storage tank can discharge part of the condensed water, and the gas storage tank also has the function of reducing the temperature of the gas. The air with lower temperature and less water content enters the dryer again, which can reduce the load of the dryer.
7, the amount of air is very large and the time is short, it is best to install a gas tank as a buffer, can reduce the number of air compressor empty heavy car, the air compressor is of great help.
8. For compressor air with system pressure below 1.5Mpa, the flow rate in the delivery pipe must be below 15m/sec to avoid excessive pressure drop.
9. Minimize the use of elbows and various valves in the pipeline to reduce pressure loss.
10. The ideal piping is that the main pipeline surrounds the entire plant, so that all aspects of compressed air can be obtained at any position. For example, when the gas consumption of a branch line suddenly increases, the pressure drop can be reduced. And in the ring main line configuration of the appropriate valve, to facilitate maintenance cut off use.
When choosing an air compressor, if the instantaneous gas consumption is large, the following key factors need to be considered to ensure that the air compressor can meet the demand: Determine the gas demand: First, accurately estimate or measure the maximum gas consumption at the moment. This usually involves setting up for production.
The processing center has high requirements for compressed air, which is mainly reflected in the stable pressure, high purity, high dryness, low oil content and so on. These requirements jointly ensure the normal operation and processing quality of the processing center. The following are specific instructions: 1. pressure is stable
We need to find out what the pressure of the air is in megapascals (MPa). First of all, we need to understand the standard value of air pressure and its unit. Under standard atmospheric conditions (I. e., average conditions at sea level), the pressure of air is usually defined as 1 atmosphere (atm). 1 atm
Q: Is there any difference between an oil-free air compressor and an ordinary air compressor? A: There is a difference. The oil content of the gas compressed by the oil-free air compressor is oil-free. For example, the water-lubricated oil-free air compressor produced by Shanghai Granklin Group, the air compressor machine
Yes, the oil-free air compressor really does not need to be refueled. Oil-free air compressor, as the name suggests, refers to the air compressor that does not need to be lubricated with lubricating oil in the process of compressing air. This type of air compressor usually uses special design and materials to ensure that the compression process
Micro-oil air compressor and oil-free air compressor, both of which are like two unique roles in the field of air compression, each has distinct characteristics and advantages. The micro-oil air compressor is like a budget-conscious engineer. While ensuring performance, it also pays attention to economy
For the maintenance of oil-free air compressors, especially the water-lubricated air compressors of Shanghai granklin group, the following are some key maintenance steps and precautions: daily inspection and maintenance daily inspection: it is recommended to carry out basic inspection of air compressors every day, including
The requirements of chemical process for compressors include the following aspects: the requirements of process parameters such as gas volume, pressure and temperature should be met. Should meet the requirements of the media characteristics. For flammable, explosive and toxic gases, the shaft seal is required to be reliable; for corrosion
Whether air compressor maintenance requires a special maintenance unit, according to the type of equipment, enterprise technical ability and cost-effectiveness of comprehensive judgment, but it is recommended to choose a professional maintenance unit to ensure the stable operation of the equipment and extend the service life. The following is a detailed analysis of the problem
Oil-free air compressor as an environmentally friendly compressed air equipment, its role is mainly reflected in the following aspects: 1. Environmental protection, no pollution, no lubricating oil demand: oil-free air compressor does not need to use lubricating oil in the working process, which avoids the pollution of lubricating oil to the environment and products.
