How should air compressor users reasonably choose energy-saving screw air compressor? Based on the experience in energy management of air compressor contracts for customers in the past two years, the editor summarizes the following points for reference 1. As needed First, find the best economic operation mode and consider the needs of future expansion in combination with customers' gas needs, and then make correct decisions. The basis of the decision is the use or use process of compressed air, and the calculation of compressed air demand, storage and future expansion. 2. Calculation of working pressure The working pressure of compressed air equipment depends on the compressor, and the maximum working pressure of compressed air equipment and pipeline determines the necessary device pressure. Pressure is a decisive factor and has a great impact on energy consumption. It is sometimes an economic choice to use different compressors for different pressure ranges. If the pressure reducing valve is used to meet the low pressure demand of gas equipment, it is an unscientific choice 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 service pressure of various machines and equipment. If the service pressure is too different, air compressors with different pressures must be purchased. Do not reduce the pressure to avoid additional expenses. 3. Air demand calculation Compressed air is a kind of power that converts electric energy into air potential energy, and uses the expansion of compressed air to do external work, but it consumes a lot of electric energy. Generally speaking, the electric energy required to compress 1m3 of air to 0.7MPa is about 7kW. Air demand: add all tools+machinery and equipment+air consumption of relevant processes+leakage+wear+future gas consumption+service factor (using standard value of 10%) 4. Determination of compressor quantity and specification (1) Choose one large machine or multiple small machines? The factors to be considered include: the cost of downtime in production, the utilization rate of electricity, the change of load (load), the cost of compressed air system, and the available floor space. Due to the cost, only one compressor in a device can supply all the air. If the user has the old air compressor as the standby machine. Then choose a large machine. The higher the power, the higher the volumetric efficiency and the lower the energy consumption. If there are no users with standby machines and the gas consumption is relatively large, two or three machines can be selected (2) Stability (always a very important problem) (3) Energy expenditure ① Pipeline leakage ② The gas demand fluctuates continuously every moment (this is the most easily ignored and the most serious) ③ The output efficiency of single machine (select the best range of output efficiency models) (4) Generalization of spare parts Pay attention to the generalization of spare parts when selecting, and the more important role is reflected in the cost of after-sales repair and maintenance, because only the generalization of spare parts can lower the price. Under special circumstances, non-universal parts will also cause production interruption due to failure to find substitutes or deliver goods in time.

 (5) Operation analysis It should be observed within one week that more than 90% of the measured energy is recovered. If the working pressure often drops within a certain period of time, the control system can make modifications according to the changes in production needs; Another factor is to check for air leakage. 5. After-sales service No matter how good the quality of the air compressor product is, it can not be guaranteed that there will be no failure in long-term use. Besides, the air compressor, like a car, needs to be maintained after a period of use. In case of air compressor failure, whether the after-sales service provided is complete, whether the relevant spare parts are reliably guaranteed, and whether they can rush to the site for quick treatment at the first time. In the increasingly competitive era, enterprises must focus on efficiency and value-added capability. Therefore, how to choose the air compressor suitable for the needs of their own enterprises is particularly important. Otherwise, it will end up: "I may have bought an air compressor of" electric tiger ", and finally wasted the electricity bill, causing unnecessary losses to the enterprise. 

Pay attention to the energy consumption ratio in order to save power: the actual exhaust volume/actual motor power consumption, the higher the value, the more power consumption. Hannos two-stage compression permanent magnet variable frequency energy-saving screw air compressor can save more than 30% of electric energy. It provides customers with the air flow calculation and reasonable selection scheme required for production for free, and creates greater value for each air compressor user. Selecting a high-quality supplier will bring greater value and value-added services. Selecting a supplier that will only sell cheap products will bring energy waste and huge losses. 24-hour service hotline 13809612360
