Quick Memorization Techniques for Construction (6)
51. The interface testing document should include the testing chain route setup, testing instruments, testingmethods, testing content, and evaluation of testingresults.
Mnemonic: Fragrant Appearance Clean Face Instrument
52. The connection between the sensor and the field controller should meet design requirements. For example, the wiring resistance of the nickel temperature sensor should be less than3Ω, and the wiring resistance of the platinum temperature sensor should be less than1Ω, and it should be grounded on the field controller side.

53. Testing and commissioning of HVAC systems
(1) Automatic adjustment of the air valve to control the newair volume and the size of the air supply volume.
(2) Automatic adjustment of the water valve to control the air supplytemperature (return air temperature) to reach the set value.
(3) Automatic adjustment of the humidifier valve to control the relativehumidity (return air relative humidity) to reach the set value.
(4) Monitoring the pressure switch alarm signal of the filter to determine whether cleaning or replacement of thefilter is needed.
(5) Monitoring fanfailure alarms and corresponding safety interlock controls; electricalinterlocks and antifreeze interlock controls, etc.

54. Required materials for fire acceptance of special construction projects:
(1) Fire acceptanceapplication form;
(2) Project completion acceptancereport;
(3) Completion drawings of construction projects involving fire safetypaper.
Mnemonic: Acceptance Form Look at Newspaper
55. For other construction projects, the construction unit should submit the fire acceptance filing to the fire design review and acceptance authority within 5 working days from the date of project completion acceptance. The construction unit should submit the following materials for filing:
① Fire acceptancefiling form;
② Project completion acceptancereport;
③ Completion drawings of construction projects involving fire safetypaper.
Mnemonic: Filing Look at Newspaper
56. Quality acceptance requirements for equipment foundation construction
1) Acceptance requirements for the concretestrength of the equipment foundation
2) Acceptance requirements for theplacement, marking height, and geometric dimensions of the equipment foundation
3) Acceptance of the appearance quality inspection of the equipment foundation
4) Acceptance of the anchor bolt inspection
Mnemonic: Wall Outside High Position
57. The foundation construction unit should provide a quality certificate for the equipment foundation, mainly checking the acceptance of its concretemix ratio, concretecuring, and whether the concretestrength meets design requirements.
Mnemonic: Curing Mix Gun
58. General procedure for mechanical equipment installation: Openbox inspection → Foundation inspectionacceptance → Foundation measurementline → Setting ofpad iron → Hoistingpositioning → Installationadjustment → Fixing and pouringgrout → Cleaning and assembly of components → Lubrication and equipmentoil → Trial operation →acceptance.
Mnemonic: Think of Tea Cooling Point, Just Adjust Sauce, Do Not Add Salt
59. Common fastening methods for threaded connections with preload requirements: Constantforce method, measurementelongation method,thermal elongation method, hydraulictensioning method.
Mnemonic: Force Plus Pressure
60. Factors affecting the installation accuracy of equipment include: Padiron embedding, equipment grouting, equipment manufacturing, environmental factors, anchorbolts, measurementerrors, equipmentfoundation, etc.
