Dry gas sealing automatic decapping centrifuge sealing characteristics
This article respectively in the pressure difference is 0, 0.15MPa, 0.25MPa, 0.35MPa, 0.45MPa, 0.55MPa under the condition of seal leakage test of. In the pressure is 0 ~ 5.5MPa, static pressure leak sealing is very small, when working, along with the added pressure difference and speed, leakage sealing is beginning to add. In other conditions (seal structure parameters constant, rotational speed, temperature and properties of invariant) the same situation, not the same pressure seal leakage, in other conditions (constant sealing structure parameters constant, medium pressure, temperature and properties of) the same circumstances, leakage seal is a kind of speed. And the theory of comparative experimental values, except at extremely low speed leakage slants big, automatic decapping centrifuge to understand the experimental results and theoretical calculation results of other comparative near, especially the change rules of common curve. In the speed less than 1000r / min, leakage far beyond the planning values, this same Rev floating speed sealing planning related, also sealed working at very low speed is put forward a new research topic for the dry gas.
Automatic decapping centrifuge introduction of dry gas seal temperature rise characteristic
The accounting result shows that: in the other conditions (seal structure parameters constant, dielectric properties, such as pressure and rotation invariant) under the condition of sealing leakage as the temperature decreases, but relatively less affected; and the experimental results show that the dry gas seal from the start to the normal working conditions, the sealing temperature rise only 27 DEG C, thus, without resulting in the medium temperature range of phase change, the temperature not too much practical significance for leakage analysis.
