Affects the large size of machineryEquipment installationAccuracy factors:
1. Base construction quality (accuracy): includes the base geometric dimensions, orientation, elevation of different planes, flatness of the upper plane, and parallelism deviation with the horizontal plane; Strength, stiffness, settlement, inclination, and seismic performance of the foundation.
2. Equipment quality of shims and anchor bolts (accuracy): includes the quality of the shims themselves, the touch quality of the shims, the perpendicularity of the anchor bolts to the horizontal plane, the quality of secondary grouting grouting quality, the degree of shim compaction, and the tightening torque of the anchor bolts, etc.
3. The choice of equipment measurement reference directly affects the entire unitEquipment installationAlign and level the post-Z mass. The equipment measurement reference is generally selected on the machined surfaces of the equipment base, machine body, housing, machine base, bed, tabletop, and root base plate.
4. Device accuracy of bulk equipment; This includes the relative motion accuracy between moving parts, the fit accuracy between mating surfaces, and the touch quality. These device precision will directly affect the operational quality of the equipment.
5. The accuracy of the measuring equipment must match the accuracy requirements of the equipment being measured; otherwise, it will not meet quality standards.
6. Influence of internal stress: Internal stresses generated during manufacturing and the equipment process can cause deformation, affecting equipment accuracy. Therefore, technical measures to prevent internal stress in equipment manufacturing and processes should be adopted.
7. Temperature changes have a significant impact on the equipment foundation and the equipment itself (including foundation, equipment, and measuring equipment), especially for large, precision equipment.
8. Operational errors: Operational errors are inevitable; the key issue is to keep them within the agreed range.
