Vacuum leak test method for small cold storage equipment

Refrigeration systems with evaporating pressure gauges close to or below atmospheric pressure must be tested for vacuum leak tests, leaving the refrigeration equipment under proper vacuum for a certain period of time, reflecting and observing whether air has penetrated into the system from the reading of the vacuum pressure gauge for inspection The sealing performance of the cold storage equipment system.

The influence of machining on fatigue life

The residual compressive stress introduced by shot blasting/shot peening is a percentage of the final tensile stress strength, and this ratio increases as the strength/hardness of the part material itself increases. High-strength/hardness metals are more brittle and more sensitive to surface defects. Shot blasting/shot peening will allow these high-strength metals to be used in fatigue-prone working conditions. Aircraft landing gear is usually designed with a fatigue strength of 300 ksi (2068 MPa), combined with shot blasting/shot peening.
