Key points for equipment inspection before project commissioning
Thread Content
I saw in the specifications that the \"three inspections and four determinations\" can be carried out in three stages: before individual unit testing, before full-system joint testing, and before testing with chemical feed. The inspection method relies primarily on self-inspection, while the “three checks” involve checking for design omissions, potential issues in construction quality, and unfinished work. It seems that it is not clear what level of compliance the equipment should reach before individual unit tests, before full-system integration tests, and before trials with chemical feedstocks. Please share your opinions or practical experiences on this matter.
Inspection items before equipment commissioning: (1) Before commissioning the equipment, the cleanliness of the main lubrication components should be checked; those that are not clean should be cleaned. (2) During equipment testing, the lubrication system should be started first; once it is confirmed that the lubrication is in place, a single-unit test can be conducted. Only after this single-unit test is successful can a system-wide joint test be carried out. During the testing process, close monitoring should be carried out of the temperature, noise, and vibration levels in the parts of the equipment that are subject to loads, pressures, or heat (such as motors, bearings, gearboxes, etc.). Any deviations from the specified limits must be addressed promptly. Any equipment issues or malfunctions (mechanical or electrical) that occur during testing must be rectified immediately. Responsibility for these issues as well as the associated costs shall be handled in accordance with the relevant provisions of the contractual commercial terms. (3) The continuous test run time for the empty vehicle and under load shall be carried out in accordance with the relevant provisions in the equipment purchase contract. (4) The installation elements that do not meet the technical requirements must be rectified, and the acceptance of such rectifications must satisfy the technical requirements.
The persons responsible for carrying out inspections at each stage vary, as do the division of tasks. The contents, methods, and measures used for inspections are different, as well as the standards and regulations that apply
It’s indeed very true, but it’s also rather general. Reputable domestic companies have operation tickets or similar documents for driving, which are very clear and detailed. Which one is the basis for driving inspections?
