【 Weak current College 】 smoke, positive pressure ventilation system device running and debugging points

First, the system should meet the following requirements:

1 system debugging, the contracting entity shall prepare the debugging scenarios, submission and approval of professional engineer; debugging is complete, you must provide complete debugging information and reports.
2 ventilation and air-conditioning system debugging, it is for the construction of the units responsible for the supervision and project management agency, design organizations and construction units of participation and cooperation. System debugging implementation can be a construction company itself or delegated to another with debugging capabilities.
3 system debugging using testing equipment and instruments, performance should be stable and reliable, its accuracy and minimum interval should be able to meet the test requirements, and should be consistent with national laws and regulations relating to the measurement and verification of the statutes.
4 ventilation and smoke control system production load, for joint commissioning and adjustment, in ventilation and smoke control equipment unit commissioning qualified. Ventilation and smoke extraction system, continuous commissioning should not be less than 2h.
5 ventilation and smoke project is installed, you must be a system of measurement and adjustment (debugging). System debug should include the following items:
1 stand-alone commissioning and debugging.
2 system production load of combined trial running and debugging.
Check the number: full.
Checking method: observation, standing, consult the debug log.
Second, the device unit test run and debug should satisfy the following requirements:
1 ventilation, smoke control system fan, the correct impeller rotation direction, stable running, no abnormal vibration and noise, the motor run power should be consistent with the provisions of the technical file. In continuous operation under the rated speed, the bearing shell 2h maximum temperature must not exceed 70 ° c; rolling bearings may not exceed 80 degrees centigrade.
2 electric control fire, smoke air valve (mouth) manual and electric operation should be flexible, reliable, signal output correctly. ，
3 fans, and other equipment at run time, the noise should not be more than the provisions of the specification of product properties.
Check quantity; paragraphs 1 and 2 according to the number representing 20% of the fan, and shall not be less than 1; paragraph 2 by the number of stroke valve system random 20 per cent and not less than 5.
Checking method: observation, standing, with the determination of the sound level meter, examining the commissioning of the records and related documents.
4 system linkage trial run, the device and the main parts of the linkage must meet design requirements, motor coordination, correct, without exception.
5 system after balance adjustment, the outlet of the air flow and design of air volume of tolerance should not be greater than 15%.
6 ventilation and smoke project control and monitoring equipment, should be the system of measurement components and executing agencies normal communication, system status parameters should be displayed properly, interlocking, automatic adjustment of the device, automatic protection should be the correct action.
Check the number: according to the system or the total number of random monitoring system, and 30% shall not be less than 1 system.
Checking method: observation, next to the station access debug logging.

Third, the system has no production load of combined trial run and debug the system total air flow results and design of air volume to debug errors should not be greater than 10%.
Check the number: the number of random checks of air duct system, and 10% shall not be less than 1 system.
Checking method: observation, standing, consult the debug log.

4. smoke joint commissioning and adjustment of results (air flow and pressure), must meet the design requirements of the fire.
Check the number: 10% by total number of checks, and shall not be less than 2 floors.
Checking method: observation, standing, consult the debug log.

5. comprehensive smoke control system for the determination of the effectiveness test project, in order to simulate the security zone under pressure variation and smoke diffusion test.
