Knowledge to be mastered in purchasing screw air compressor

First of all, screw air compressors should be selected according to specific needs. There are many types of screw air compressors. Screw air compressors are more commonly used air compressors, including small and medium-sized piston machine air compressors, medical small and medium-sized silent diaphragm vacuum pump air compressors, medium and high-pressure air compressors with strong atmospheric pressure, high-power diaphragm vacuum pump screw air compressors, low-voltage environmental protection and energy-saving low-voltage air compressors, high-efficiency environmental protection and energy-saving rare earth permanent magnet variable-frequency air compressors, China's first-class environmental protection and energy-saving air compressor is an integrated one-piece air compressor and a convenient screw air compressor. There are many product varieties. Customers can choose the air compressor according to other products they must have.

Master what kind of screw air compressor must be purchased, so that you can choose well-known brands and brand air compressors, which can ensure product quality and after-sales maintenance service. Generally, many customers will choose famous overseas brands. What I want to say is that with the development trend of China's economic development, air compressors have long been a particularly perfect commodity in China and have been successfully applied in the field of subway stations. It is applicable to well-known brands in China, such as Demeng, and professional screw air compressor manufacturers.

When buying screw air compressors, the price is also a matter of great concern to many customers. Air compressors are similar to automobiles. The purchase time depends on the overall purchase cost, and the gas supply also depends on the power consumption and cooking oil consumption. For example, when you buy a car at a high price, it is very good to drive, but the fuel consumption is shocking, and the gasoline cost is unaffordable. The air compressor is the same. The time you buy it depends on the environmental protection and energy conservation specifications. You don't have to choose the poor one. You can choose the variable frequency one, which belongs to one-time project investment. Although you spent a lot of money when you bought it at that time, you saved a lot of water and electricity bills in one year, It's also equivalent to buying a new device, isn't it?

But if you want to be cost-effective, buy a low equipped air compressor that is more suitable and cheaper. As a result, it doesn't take much time. There are a lot of problems, many repairs, delay in work and time, and delay in production and manufacturing. I firmly believe that you will be very upset at that time.

After sales maintenance service is also a concern of many customers when purchasing screw air compressors. When consulting with the manufacturer, you must ask about the after-sales service. Since the air compressor is a mechanical equipment, it will be abnormal under long-term operation. If the manufacturer promises after-sales service, then wait for buying a new air compressor again! However, for some small well-known brands, although the service commitment is in the aspect of after-sales maintenance service, the price is very high in the future maintenance level. In a word, choosing a well-known brand of air compressor can ensure the quality.
