Easily damaged parts in screw pump
The stator [1] is an important part that is easily damaged in the screw pump, and the accuracy of the stator tooth curve and the correct material selection must be considered in the design and development, which directly determines the length of the stator life.
Generally, the hardness of the rubber stator should be considered: the medium containing particles should be lower, and the pure and net medium should have a higher hardness; Medium with small viscosity, hardness can be appropriately high:
The reliable basis can be obtained by selecting the formula of stator rubber for dynamic test. Because even if the hardness is close to the conventional physical properties, if the formula is different, there is still a big gap in the results of the dynamic test.
The selection of the rubber material formula must take into account what kind of medium (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 tearing strength. The performance of rubber after injection, not only can determine the life of the stator, and even affect the normal operation of the pump, for example: the oil medium must be selected, because many rubber is not resistant to oil media; Conveying high temperature medium should choose fluorine rubber and so on.
Hardness is a very important indicator of the performance of the stator rubber: it is expressed by quantifying the degree of resistance of the elastic surface to the quantitative load in the vertical direction. Shore (A) hardness (GB/T 531-1983) is the most commonly used in China.
