The effects of pressure ratio, rotational speed, external cooling conditions, and packing ring material on the temperature distributions are discussed in detail.
The partition coefficient determines how much heat is transferred to the piston and packing ring sides.
This experimental setup allowed the dynamic temperature of the packing ring surface in different working conditions to be obtained.
When frictional heat was transferred along the axle direction, this disadvantage made it harder for the heat to reach the cover side than the crank side, and therefore the temperature declined from packing ring 1 to 8.
The results indicate that the maximum temperature occurred at packing ring 6 when the pressure ratio was lower and at packing ring 1 when it was higher, which is similar to the group D results shown in Figure 10.
The radial temperature distribution of each packing ring was consistent in this condition.
0, the maximum temperature of the packing rings occurred at packing ring 6, and the temperature at the cover side was lower than that at the crank side.
However, the highest packing ring temperatures were 416.
The third of the packing ring area closest to the friction contact surface featured the largest temperature gradient in the radial direction.
Instructions/Remarks: Packing Condition:The Packing Ring Shall Be Securely Packed In Gunny Bag Lining Or Any Other Suitable Alternative To Avoid Damage During Transit.
Also, many packing rings will shrink over time, and misdirected cooling water will seep outside the rings, causing them to become hard and fail.
Ticona also used packing rings molded from PPS--this time Fortran 1140--for the new tower.
