The quality inspection before the installation of fire discharge to smoke mainly includes the following steps:
1. Check whether the model and specifications of the fire exhaust fan meet the design requirements. At the same time, check whether the fans number, transmission method, leaf rotation direction, and air outlet position are correct.
2. Check the shell and impeller of the fan to ensure that there are no flaws that affect work efficiency without depression.If there is a mild damage, it should be installed after repair.
3. Check the balance of the impeller of the fan. You can use your hand to push the impeller. If each rotation is suspended, it is considered to meet the quality requirements in the original position.
4. The axis of the fire foam fan should be kept water balance.If the fan is connected to the electric motor to use the joints, the central line of the two axis should be on the same line.The axial tilt allowable deviation is 0.2%, and the allowable deviation of the radial displacement is 0.05mm.
5. Check the foundation of the fan. If you find that there are not solid places, you should take reinforcement measures.
6. Check whether the motor and transmission mechanism are complete and reliable, and whether the protective cover is tight.
7. After connecting the power supply, the trial transportation, listening to the noise and vibration, the debugging of the next step of the ventilation pipe system can be performed after confirming that there is no abnormal phenomenon.
8. In accordance with the requirements of the product manual, do the preparation of the ground protection of the body (phase line and neutral line) and the cross -connection line.
9. Check the bracket of the system pipeline to ensure that the strength and stiffness of the bracket meet the requirements and fix it.
10. Whether the slope of the system pipeline meets the requirements of the design regulations for inspection and acceptance.
11. Review and inspect the installation position of the fan and the connection method of the duct. The installation size of each component is accurate, the connection is firm and reliable, the seal is intact, and it is convenient for operation and maintenance.
12. Adjust the adjustment valve to the required air volume state (generally the situation is full), and then start the fan until the rated speed is reached and then gradually open the large air volume valve until the required working point.
13. Turn off all valves and cut off the power switch.
After the above steps are completed, the fire smoke exhaust fan can be installed.The above is the quality inspection before the installation of fire fire exhaust fan. I hope it will be helpful to you.If you want to know more about related information, please pay more attention to us--
