The engineering commissioning process and precautions of engineering commissioning

1.If the two parties agree that a test run is required, the test content shall be consistent with the installation scope contracted by the contractor.

2.If the equipment installation project has the conditions for stand-alone no-load commissioning, the contractor shall organize the commissioning and notify the engineer in writing 48 hours before the commissioning. The notice includes the content, time, and place of the test.

The contractor prepares the test record, and the employer provides the necessary conditions for the test run according to the contractor's requirements. The commissioning is qualified, and the engineer signs the commissioning record.

3.If the engineer is unable to attend the commissioning on time, he or she must submit a written request to the contractor for an extension of time 24 hours before the start of the commissioning, and the extension shall not exceed 48 hours. If the engineer fails to request an extension within the above time and does not participate in the commissioning, the commissioning record shall be recognized.

4.If the equipment installation project meets the conditions for no-load linkage commissioning, the employer shall organize the commissioning and notify the contractor in writing 48 hours before the commissioning. The notice includes the content, time, place and requirements for the contractor, and the contractor makes preparations as required.

If the test is qualified, both parties shall sign the test record.

5.Responsibilities of the Parties:

1).If the test run fails to meet the acceptance requirements, the employer shall request the design unit to modify the design, and the contractor shall reinstall it according to the modified design. The employer shall bear all the costs of modification of the design, dismantling and re-installation and the additional contract price, and the construction period shall be extended accordingly.

2).If the test run fails to meet the acceptance requirements due to equipment manufacturing reasons, the equipment purchaser shall be responsible for re-purchase or repair, and the contractor shall be responsible for dismantling and re-installation. If the equipment is purchased by the contractor, the contractor shall bear the costs of repairing or repurchasing, dismantling and reinstalling, and the construction period shall not be extended; If the equipment is purchased by the employer, the employer shall bear the above-mentioned additional contract price, and the construction period shall be extended accordingly.

3).If the commissioning fails to meet the acceptance requirements due to the contractor's construction reasons, the contractor shall reinstall and test the commissioning according to the requirements of the engineer, and bear the cost of reinstallation and commissioning, and the construction period will not be extended.

4).Unless the commissioning costs have been included in the contract price or otherwise agreed in the special terms, the commissioning costs shall be borne by the employer.

5).If the engineer does not sign the test record after passing the test, 24 hours after the end of the test, it is deemed that the engineer has approved the test record, and the contractor can continue the construction or go through the completion procedures.

6.If the employer requires that the project be carried out before the completion and acceptance of the project or requires the cooperation of the contractor, the contractor shall obtain the consent of the contractor and sign a supplementary agreement.

Engineering commissioning refers to the trial operation of equipment, circuits, pipelines and other systems during the completion period of the project to see whether it is operating normally and whether it meets the requirements of design and specifications. There are mainly stand-alone test, linkage test, no-load test, and on-load (loaded) test, which are different test methods taken according to different requirements.

Engineering test is the no-load operation of the drive device installed on site or the load test run of a single machine or unit with water, air and other medium to test its mechanical properties in addition to being affected by the medium.

Roads outside the market can be selected, and the road test time is long, which can reflect the performance of the vehicle in different driving conditions. Start on the spot and accelerate on the spot, and slam on the accelerator to see if the acceleration is sensitive. Check the speed of the vehicle on the slopes.

If the performance is not good, it means that the engine is not powerful enough.

The manual transmission clutch should be smoothly engaged and disengaged thoroughly. Otherwise, it will be difficult to start, driving weakness, climbing weakness, transmission gear crashing sound, starting shaking, etc.

At a speed of 15 km/h, turn the steering wheel to the left and right to see if it is flexible and whether there is a positive moment. Spread the steering wheel and should not deviate.

Suggestion: Tip 1: Test drive on a site or section of the road that is as spacious as possible, and pay attention to surrounding vehicles and pedestrians to avoid accidents.

Because you are new to these test drive vehicles, you don't know its bottom line, in case of misoperation or loss of control of the vehicle, it may cause unexpected losses;

Suggestion 2: Find a reference standard, good and bad are relative, if you have driven a few cars, it is difficult for you to make a judgment on a car that you are not familiar with, as if you have only driven Xiali, and you want to change a car of about 100,000 yuan, Volkswagen cars are relatively easy to test drive, basically all models can be found to test drive, Volkswagen performance is above the medium level, is a good reference sample.

"Engineering commissioning" refers to the completion of the engineering equipment, circuits, pipelines and other systems of the trial operation, to see whether the operation is normal, whether to meet the design requirements, mainly stand-alone commission, linkage commission, no-load commission, on-load (load) commission, is according to the requirements of different different test methods.

If the two parties agree that a test run is required, a test run shall be organized, and the test content shall be consistent with the installation scope contracted by the contractor.

1.Stand-alone no-load test No-load trial of a single equipment.

2.Linkage no-load test The whole set of equipment or multiple equipment together for no-load trial.

3.Feeding test run according to the normal working mode of test run.

The on-site installation of the drive device is running at no load or the load test of the single excition-resistant fiber machine and unit is carried out with water, air and other medium to test the manufacturing and installation quality of the mechanical properties of Changfang except for the influence of the medium.

Engineering commissioning refers to the trial operation of equipment, circuits, pipelines and other systems during the completion period of the project to see whether the book is pure and clean and whether it meets the design and specification requirements.
