Because of its product characteristics and technical advantages, the laminated screw sludge dewaterer has been recognized by customers. But how to choose high-quality and reliable screw-type sludge dewatering equipment?

The following four aspects should be paid attention to when choosing and purchasing the laminated screw sludge dewaterer:

1. Spiral Shaft

As one of the core dewatering parts of the screw stacker, the importance of the shaft has become very obvious. Normally, special screw shafts should be selected for materials with different characteristics in order to achieve the best treatment effect and maintain longer service life, especially for inorganic materials and organic materials, the difference of screw shafts should be taken into account in order to avoid shaft blockage and wear. Simply put, although the appearance of the laminator equipment looks similar, but as the "heart" of the equipment, the spiral axis is different. The core technology of the equipment is also reflected in the spiral axis and ring, which is actually very technical.

2. ring piece

Some manufacturers, through simple imitation production, found that after several months of using the equipment, serious production faults such as wear and tear of the shaft and the core dewatering parts of the movable fixed ring occurred, which is related to the design parameters and processing accuracy of the ring and spiral shaft.

In addition, some manufacturers claim that all stainless steel is used in the concentrating and dewatering sections of the equipment, which is actually a misunderstanding. For the materials of the concentrating and dewatering sections of the equipment, different sludge properties should be taken into account, and stainless steel must be the best choice. For example, the CFRP materials currently developed have more advantages in corrosion resistance and wear resistance than stainless steel materials. 。 In addition, some irresponsible manufacturers in stainless steel quality also through sub-prime, 202 stainless steel or even 201 stainless steel impersonate 304 stainless steel, I Division only do high cost-effective products.

Therefore, the ring of the laminated screw sludge dewaterer is also one of the aspects that should be paid attention to when choosing and purchasing equipment.

3. motor

The quality and service life of the motor are also very important. As a necessary part of routine inspection, it plays a leading role in the smooth operation of the laminated screw sludge dewaterer.

4. Pre-sale/after-sale service

If there is no good pre-sale and after-sale service for the laminated screw sludge dewaterer equipment, it will also bring inconvenience to users and affect the normal use of the equipment. Good equipment should have perfect pre-sale and after-sale service before it can be purchased at ease. The delivery and use of equipment and the acceptance and completion of the project are not the end of the service, but the beginning of the service.
