Many users have some doubts when choosing to buy a compressor: What compressor is good? How to choose the compressor? The price of the compressor and so on. In view of the above problems, Simpson Compressor provides a few selection guides for customers.
In terms of brand selection, compressors are also divided into imported brands and domestic brands. Imported compressors are more expensive and their quality is relatively better. However, the price-performance ratio of domestic brands is definitely not bad. Many domestic brand compressors have good brands and cheap prices, and are the first choice for most small and medium-sized business users.
The more powerful the compressor, the more expensive it is. How much power compressors need to be purchased depends mainly on the displacement of the unit, which must meet the normal production of the plant without causing waste. It is particularly important to emphasize that some industries do not have high pressure requirements, and only require low-pressure machines within 5kg pressure, such as textiles, ceramics, packaging, chemicals, etc., and the pressure of compressors in the market is generally 8kg. You must know that every 1kg pressure The power consumption is 7% more. If normal pressure models are used in the low-pressure industry, a lot of energy will be wasted. Therefore, it is necessary to choose low-pressure large-displacement compressors according to actual use.
As for the type, oil-free screw compressors are much more expensive than oil-lubricated screw compressors with the same power. Oil-free compressors have higher requirements for the use of the industry. They are generally suitable for food, pharmaceutical, electronics, and precision instruments. . Inverter compressors are more expensive than industrial frequency compressors, and permanent magnet inverter compressors are more expensive than inverter compressors because they are more efficient and energy efficient.
