How to check the leveling of shims for static equipment
Thread Content
According to GB 50231, the method for leveling the shims of static equipment and the equipment bases requires only listening for sounds after tapping; if a feeler gauge is used, what size of feeler gauge should be employed for inspection? The on-site construction party believes that the requirement to use a 0.05 mm feeler gauge as specified for moving equipment is too strict. Do any of you who have experience in engineering know something about this? Is a 0.5mm feeler gauge acceptable?
In the inspection for leveling equipment shims, the specifications for using feeler gauges are usually determined based on the precision requirements of the equipment and the actual conditions. Standard GB 50231 mainly mentions using tapping to check the contact condition of shims, with no specific regulations provided regarding the specifications of feeler gauges. If the on-site contractor considers the 0.05 mm feeler gauge requirement to be too strict, it is possible to consider relaxing the standard accordingly. Generally, using a 0.5mm feeler gauge is a common practice; it can be used to check for any significant gaps and to ensure that the installation accuracy requirements for ordinary equipment are met. When determining the specific gauge specifications, it is best to consider the installation requirements and expertise of the equipment manufacturer. .
