Many people don't like summer. Because the hot climate can make people uncomfortable, some industrial equipment parts are also the same. They are also very afraid of high temperature, because high temperature will adversely affect their working conditions, such as piston rods. The piston rod is an important part of many equipment, and its operating conditions are also strict. How will high temperature change it?
The gas pressure and the inertia force on the piston change periodically, so the gas pressure on the piston is very high instantaneously. Not only that, but the piston also receives the periodic impact effect of the side pressure when the connecting rod is skewed. The combined effect of gas pressure, reciprocating inertia force and side pressure may cause defects such as piston deformation, piston pin seat cracking, and side wear of the piston.
In order to prevent the occurrence of the above phenomenon, the piston rod must have sufficient strength and rigidity, and be light in weight. However, under the influence of high temperature, the strength of the piston rod material will inevitably decrease, and the thermal expansion of the piston will increase, which will damage the normal gap between the piston and the cylinder wall, thus presenting a series of adverse reactions.
