The scientific calculation of plant gas consumption is the core link to optimize the compressed air system and reduce operating costs, which needs to be systematically evaluated in combination with actual production scenarios and equipment characteristics. The specific calculation can follow the following steps:
1. Combing the gas equipment list
and comprehensively counting the terminal equipment (such as pneumatic tools, spraying devices, packaging machinery, etc.) relying on compressed air in the factory, and recording the rated gas consumption of each equipment (usually marked on the equipment nameplate or technical documents). If the air consumption of the equipment is in units of "liters per minute" or "cubic feet per minute", it needs to be uniformly converted to standard cubic meters per minute (Nm & sup3;/min) for unified calculation.
2. Calculate the theoretical total air
consumption Add the rated air consumption of all equipment to obtain the total basic air consumption. For example: 10 equipment respectively consume 1.5Nm & sup3;/min, 2.0Nm & sup3;/min, 1.0Nm & sup3;/min…, then the theoretical total is the sum of the air consumption of each equipment.
1. The introduction of simultaneous use coefficient
to consider the actual production of equipment is not all at full capacity at the same time, according to the production rhythm set simultaneous use coefficient (usually 0.6-0.9). If the coefficient is 0.75, the adjusted air consumption is the theoretical total × 0.75.
2. Reserved Expansion Space
In order to cope with the increase of production capacity or equipment, 10%-20% redundancy shall be reserved on the basis of calculation results to ensure the scalability of the system.
1. Pipeline leakage control
5%-15% leakage of compressed air pipeline due to joint sealing, pipe wall roughness and other factors, the corresponding proportion of air consumption should be increased on the basis of the calculation results.
2. Pressure attenuation compensation
There is pressure attenuation when high-pressure gas is delivered to the terminal, which needs to be compensated by increasing the output pressure of the compressor or configuring the gas storage tank. For example, if the target pressure is 0.8MPa and the terminal equipment demand is 0.6MPa, the air consumption calculation needs to be adjusted according to the pressure difference.
1. Confirm the output capacity
When selecting the compressor specification according to the final air consumption, pay attention to the actual displacement of the equipment under the target working pressure (consider the compressor efficiency attenuation). For example, if the target pressure is 0.7MPa, check the compressor performance curve to confirm whether the effective output at this pressure meets the demand.
2. Intelligent control and optimization
The compressor using frequency conversion control technology can automatically adjust the operating power according to the actual gas consumption to avoid energy waste. For example, when the gas consumption is reduced, the compressor will automatically reduce the frequency operation to keep the pressure stable and reduce the energy consumption.
1. Oil-free design ensures accurate gas
use. Single screw and star wheel precision meshing technology is adopted to replace traditional lubricating oil with pure water. The purity of output gas fully meets the requirements of precision equipment in the factory to avoid equipment failure or product quality problems caused by oil pollution.
2. Efficient sealing reduces leakage risk
. The combination of precision machining and water lubricating medium can effectively reduce gas leakage and improve system efficiency. With the intelligent control system, the gas consumption can be monitored in real time and the output can be automatically adjusted to ensure that the compressed air supply and demand are accurately matched.
3. Low maintenance cost and high reliability
, no complicated oil circuit system is needed, which greatly reduces the frequency of filter element replacement and the cost of consumables. Water lubrication medium with environmental characteristics, in line with the requirements of sustainable development. Integrated online monitoring function, real-time feedback of gas quality parameters, to ensure stable and reliable plant gas.
In summary, through systematic calculation and scientific selection, combined with the technical advantages of Granklin water lubricated single screw compressor, the factory can realize the efficient use of compressed air and cost control, and provide reliable guarantee for production and operation.
Analysis of the difference between 7.5kW permanent magnet variable frequency screw air compressor and power frequency model In the industrial field, screw air compressor with 7.5kW power section is widely used because it is suitable for small and medium-sized gas usage scenarios. Permanent magnet variable frequency model and power frequency model as two major technical routes, in energy efficiency
The air supply of an air compressor is determined according to its model, power and design parameters, so the air supply will vary with different air compressors. In order to obtain accurate air supply data, you can refer to the technical specification sheet or user manual of the air compressor.
Screw air compressor maintenance costs vary due to a variety of factors, including the region, service providers, the specific state of the machine, brand and model. Generally speaking, the maintenance cost of the screw air compressor is usually between a few hundred yuan and several thousand yuan. Basic maintenance cost: basic
Water-lubricated air compressors usually use water softeners. The following are some explanations and summaries about the use of water softeners in water-lubricated air compressors: the importance of softening water quality: water-lubricated air compressors use water as a lubricating and cooling medium, so the quality of water is directly
Dear readers, have you ever been confused when choosing a volumetric air compressor or a screw air compressor? Don't worry, today we will take you to explore the secrets of these two air compressors in a relaxed and pleasant way. First, let's look at the volume.
National standards for the design life of pressure vessels vary depending on the type of vessel, its use, and the regulations of each country. In China, according to the national standard "Pressure Vessel Safety Technology Supervision Regulations", the design service life of general pressure vessels is 15 years.
This depends on the pressure of the air outlet of your air compressor, that is, the working pressure of the air compressor. The purchase of the pipeline is determined according to the pressure of the air compressor. Generally, the pressure of 3-5KG is called low pressure, 7-13KG is called medium pressure, and more than 13KG is called high pressure.
The semiconductor manufacturing process requires extremely strict cleanliness of compressed air, and its core is to control the content of pollutants such as particulate matter, oil and moisture in the gas to ensure that precision devices are not contaminated during the production process.
