Analysis of the Causes of the Connecting Pin Wear
The sales staff of the sales department of a production plant waited for the two pressure gauges because the connecting rod pin between the sealing sheet and the two banks was worn out, and the thermal resistance ground the pin hole at the upper end of the connecting rod from a round hole into a long hole of a stainless steel pressure gauge. The user needs to analyze the reason for the loss of the function of the instrument.
Preliminary analysis of the reasons for the wear of the connecting pin is as follows:
1. The connecting pin is thin, only 1.2mm, and the material is brass, which is soft and has poor wear resistance;
2. Frequent vibration in the on-site working environment or large pulse changes in the measured pressure gauge are the main reasons for the wear of the connecting pin. The pin hole at the upper end of the stainless steel pressure gauge connecting rod is ground from a round hole into a long thermal resistance hole. It can be imagined that there will be a field working environment Vibrations are frequent.
