Selection of screw air compressors through power system and power consumption fluctuations—Shared by Sollant

Every user will consider several factors when checking a large screw air compressor, such as energy saving, maintenance and stability.

First, the limitations of the power system Consider the power supply voltage used. The low-voltage system (usually 380 volts ~ 460 volts) is not suitable for screw air compressors above 315 kilowatts. Secondly, consider whether the impact bearing capacity of the power grid is sufficient when the large screw air compressor is started.

Second, the impact of air consumption fluctuations Due to seasons, time differences or other factors, the change of compressed air exceeds the range (depending on the model), or the actual use of compressed air may be much lower than the estimated value before purchasing the screw air compressor, a single screw The air compressor will inevitably cause energy waste due to discharge or unloading.

Third. Safety of gas consumption Abnormal tripping or shutting down is a potential threat to stop production. In order to reduce the risk of production interruption, it is necessary to consider setting up backup machines. The probability of doing an operation with one machine can be as high as 50, one backup). Users may not be able to accept the investment cost. When choosing a large-capacity screw air compressor, it is very important whether the entire compressed air system can achieve energy efficiency.

How to choose the right air compressor capacity is not a simple matter. It involves a wide range of aspects. The following basic principles are listed:

1. Pneumatic equipment manufacturers are required to provide air consumption and air consumption changes as the basis for analyzing and selecting the capacity of screw air compressors. Ordinary users ask screw air compressor suppliers to estimate the air consumption of certain pneumatic equipment, which is undoubtedly putting the cart before the horse.
2. If there are seasons, time differences or other factors that will affect the change of air consumption, it is also necessary to evaluate and list them in detail. You can consult the screw air compressor supplier or professionals to obtain corresponding countermeasures.
3. Considering the forward-looking of the whole plant, list the estimated gas consumption of short-term, medium-term and long-term investment plans respectively.
4. Do not insist on the concept of consistent type, type and capacity of screw air compressors to make spare parts interchangeable. In the case of a wide range of air consumption, choosing a compressed air system with a large capacity and a small capacity screw air compressor can provide a more flexible strain range. Of course, there will be unexpected energy-saving effects. 5. Configure several large-capacity screw air compressors and half-capacity small screw air compressors. If you use a compressed air system with 3-5 or more screw air compressors, as long as you carefully select the appropriate control mode and peripheral equipment, you don’t need to consider the compatible configuration of large-capacity and small-capacity screw air compressors, thus avoiding Possibility of idling small capacity screw air compressor.
