How to select the portable air compressor
1. Model selection will be based on actual air use requirement
Combining the needs of customers, finding the best operating economy, and expanding the scale in the future will require a lot of decisions. The basis of the decision is the purpose or use process of compressed air. It focuses on calculating the air demand, reserves and room for future expansion. Pressure and flow are both decisive factors and have a great impact on energy consumption. Different pressure ranges and different The flow conditions of different compressors may sometimes be economical.
Commonly used international standards for selection are: AP1613, AP1614, AP1615, AP1617, AP1618, AP1619.
2. Calculation of work pressure
The equipment that compresses the gas determines the necessary working pressure depends on the compressor, equipment, pipeline, the highest working pressure determines the necessary device pressure, and the air consumption location uses a pressure reducing valve to meet the equipment requirements, in extreme cases, a A single air compressor is very uneconomical.
Working pressure: end user + final stage filter + piping system + dust particle filter + dryer + compressor adjustment range
The higher the pressure, the greater the power consumption, and the pressure drop caused by the size and length of the piping must be considered. List the operating pressures of various models. If the operating pressures are too different, you must purchase air compressors with different pressures. Do not use at reduced pressures to increase costs.
3. Calculation of air demand
Compressed gas is a clean power that converts electrical energy into air potential energy and uses the expansion of compressed air to do external work. However, it consumes a lot of electrical energy. Generally speaking, the electric energy required to compress 1m? of air to 0.7MPa is about 7kW. According to statistics, the power consumption of the air compressor station accounts for about 20% of the total power consumption of the entire enterprise. This means that saving compressed air and rationally using compressed air will bring you new profit margins!
Air consumption: Combine all tools + machinery and equipment + relevant process air consumption + leakage + wear + future air consumption + usage coefficient (standard value 20%)
Fourth, the number of compressors and the determination of specifications
According to the required degree of flexibility + control system + energy efficiency
(1) Choose one big machine or multiple small machines?
The cost of downtime during production, the utilization rate of electricity, the change of load (load), the cost of the compressed air system, and the available floor space. Due to cost reasons, only one compressor is used to supply all the air in a device, so this system can prepare a quick interface of a mobile compressor for connection when it is used, and an old air compressor can be used as an inexpensive The reserve power provides the reserve gas source.
(2) Stability (an issue that has always been very important);
(3) Energy consumption expenditure
● Piping leaks;
● The demand for air fluctuates every moment (this is the most neglected and the most serious)
● The output efficiency of a single machine (choose the model with the best range of output efficiency)
(4) standardization of spare parts
The optimal combination of multiple 110KW models may be 40-160m³/min, the best choice for the air range.
(5) Operational analysis
It should be observed within one week, and more than 90% of the measured energy recovery is recovered. During a certain period of time, the working pressure often drops. The control system can be modified with reference to the changes in production to improve the use of the air compressor. Another factor is to check for air leaks.
Pay attention to the ratio of energy consumption to save power: actual displacement/actual motor power consumption, the larger the value, the more power consumption.
