What material is the screw pump stator generally made of?
The selection of the rubber material formula must take into account the medium to be transported (the composition of the medium and the corrosiveness of the medium, etc.) and the temperature of the medium, as well as the hardness of the rubber, the expansion rate of the rubber in the medium and the breaking strength. The performance of rubber after injection can not only determine the life of the stator, but also affect the normal operation of the pump. For example, NBR must be selected for conveying oil media, because many rubbers are not resistant to oil media; fluorine should be selected for conveying high temperature media. Rubber etc.
What should be paid attention to when choosing a screw pump stator?
Hardness is an extremely important indicator of the performance of stator rubber: it is quantified and expressed by the degree of resistance to force when the elastic surface is quantitatively loaded in the vertical direction. Shore (A) hardness is commonly used in my country (the measurement standard is GB/T531-1983). Usually, the hardness of the rubber stator should be considered: the medium containing particles should be lower, and the pure medium should be higher hardness; the medium with lower viscosity, the hardness can be appropriately higher: the dynamic test of the formulation of the stator rubber can be reliable. basis. Because even if the hardness is close to the conventional physical properties, if the formula is different, the results of the dynamic test are still very different.
