High-quality screen changers are compared with low-quality screen changers in the following five aspects

We are one of the earliest domestic manufacturers to develop non-stop hydraulic screen changers, and have more than 20 years of rich and successful experience in continuous innovation in the field of screen changers. The screen changer products we provide have optimized flow channel design, so that the extruder can be completely switched without stopping and leaking, and the defects of the product caused by bubbles in the screen changing process are completely avoided. For high-quality screen changers and low-quality screen changers, the following five aspects are compared.

1. Design
The appearance of the screen changer looks similar, but the internal design is different. The big difference lies in the different sealing methods. At present, the reliable sealing method is the hard sealing method with gap matching. At that time, the technical content of this is that there must be a gap for pushing and pulling activities to change the screen, and at the same time, there must be no leakage. There are not many screen changer manufacturers on the market that can do this. Another way to seal is through soft sealing, that is, using materials of different hardness for sealing. When this type of screen changer is pushed and pulled under high-pressure production conditions, the softer sealing material will wear, the gap will increase, and leakage will inevitably occur. Some will leak when installed, and some will leak after a short period of production, so the difference between good and bad can be distinguished in design.
2. Material
The key components of high-quality screen changers are made of special alloy steel. After corresponding heat treatment, the surface hardness reaches a reasonable height, so the friction of the hard seal ensures the matching accuracy of the gap. The hardness of ordinary steel cannot be achieved, and pushing and pulling will cause strain and leakage. At the same time, the material of the screen changer connection body will also be different, including forging parts, steel parts, and castings, which will naturally be reflected in price and quality.
3. Processing technology
In order to ensure the surface hardness of the key components of the screen changer, the corresponding processing technology must be carried out. Simply processing into machined parts with the same appearance cannot guarantee the quality of the screen changer. Even if there are relevant processing technologies, different processing methods and processing time will also cause different quality of the screen changer, which is also the difference in the quality of screen changers on the market.
4. Assembly
Professional screen changer manufacturers have accumulated and rich experience in assembly. It is precisely because of the difference between professionals and non-professionals and the different mastery of core technologies that the essential difference between screen changers is whether they leak or not.
5. Price
I believe that the first question everyone asks when consulting about screen changers is: How much does a screen changer cost? The cost of mechanical processing is transparent and can be calculated. When you blindly pursue low prices, how can you guarantee the quality of the screen changer? The necessary business behavior is not to do Leifeng. A low-priced screen changer must be a low-quality screen changer. Of course, a high-priced screen changer is not necessarily a high-quality screen changer. What is certain is that a high-quality screen changer is definitely not a very cheap screen changer.
