For skid-mounted hydrogen compressors, if the horizontal tilt error of the bearing shells in the unit is too large, how can this be resolved?

Since the installation team did not understand the technical requirements for installing hydrogen compressors, they proceeded with the installation of the skid-mounted hydrogen compressor unit without first disassembling it to check its levelness, nor did they level the surfaces where the bearing shells met the machine body. Secondary grouting was carried out without these steps. Now, tests are needed to adjust the unit; however, upon disassembling the main unit, it was found that the bearing shells were tilted excessively, which could lead to serious piston damage and increased vibration in the unit, posing safety risks. We are seeking advice from those with more experience on how to level and align the entire unit without damaging the existing concrete foundation, while ensuring a safe and long-lasting operation that does not result in damage to the unit or any safety hazards I hope the seniors will not hesitate to share their insights. Urgent, really urgent! Urgent! Urgent! Urgent! ! !
First, it is necessary to recheck and adjust the levelness and alignment of the bearing shells; if needed, they must be disassembled again so that the fuselage and the bearing shells can be leveled. Next, professional measuring tools should be used to check the levelness and verticality of the unit, to ensure that it meets the technical requirements. Without the need to damage the foundation during pouring, the levelness of the unit can be adjusted by modifying the support points or shims. The entire adjustment process needs to be carried out slowly, step by step, and measurements need to be taken again after each adjustment until the error is within the acceptable range. It should be noted that the adjustment process must ensure safety to avoid damaging the unit. .
Currently, the after-sales technical staff from the manufacturers insist on breaking down the foundation, leveling it again before pouring new concrete to correct the alignment; they do not allow adjustments to be made by using shims or setting up supports, which is quite frustrating.
If the manufacturer insists on demolishing the foundation, leveling it again, and pouring concrete anew, it is likely because they consider this to be the most reliable method to ensure long-term stable operation. Although this increases the workload and costs, it may be to avoid greater problems and risks in the future. It is possible to discuss this with the manufacturer to find out what is causing their concerns; if conditions permit, it is still best to follow the methods they recommend. . Safety and the long-term stable operation of the crew are the most important considerations. .
