Quantitative indicators for the evaluation of wear of mechanical seals:

In order to calculate the CARTEX mechanical seal and predict the reliability of the machine parts during friction, select the parts materials reasonably under certain conditions of use, and determine the size and structure of the mating surfaces, it is necessary to know the basic law of material wear. According to the general assessment method of surface damage, the wear can be determined according to the following indicators:

(1) Line wear h, wear volume or wear weight, line wear refers to the change in surface size when damaged, this change is measured in the direction perpendicular to the friction surface; wear volume and wear volume It is the change in volume and weight of an object before and after it is worn.

(2) M3200 mechanical seal modification wear rate: it represents the relationship between the amount of wear and the stroke in the friction stroke where wear occurs, that is, the amount of wear per unit friction stroke. If the amount of wear and the friction stroke are expressed in the same unit, the wear rate is a dimensionless quantity.　　402.html,

The critical conditions related to the transformation of mechanical seal wear form are as follows: 'Mechanical seal wear volume-wear time curve (wear process):
