The results showed that the melting rate of SSE with grooved
barrel was significantly higher than that of conventional SSE and the melting rate reached the maximum with a specific combination of the groove number and groove width.
Since the barrel is essentially a pipe, the pressure from the grooved
feed throat transfers through the barrel, counteracting the discharge-pressure resistance.
systems help alleviate many of the problems associated with using traditional joining methods in the field.
mechanical piping systems were used in all areas of DOKE including HVAC, fire protection and desalination, with pipe sizes ranging from 2" up to 60" (50.8 to 1,525 mm) and pressure ratings of up to 17.75 bars.
piping systems have been used for more than 85 years, and their list of benefits continues to impress.
This is the reason why many polyurethane covers are grooved
. Presently, polyurethane covers can be manufactured to around 55 P & J and under.
Tests were conducted comparing the new helical design against competitive standard grooved
pins and the company's knurled pins.
The essential feature of the grooved
feed section is increasing the participation of polymer friction in the solid state through the forced movement along the grooves and consequently increasing the polymer flow rate.
In a conventional Uni-Run conversion, the lower rolls or dryers are grooved
and drilled across the entire roll width, while this is necessary for holding a wet sheet, it is not necessary in the third section where the sheet has more strength.
He then turned to an idea that had first surfaced more than a decade before in connection with the diffusion of adsorbed atoms on a grooved
Eberhard Gruenschloss of the IKT University in Stuttgart, Germany, recently developed the first helically grooved
bimetallic barrels for abrasive materials.
A new mechanism is described that allows adjustment of the groove geometry in grooved
fixtures were fabricated to compress the o-ring height from 2.62 to 1.75 mm, as in the exciter o-ring groove.
