1 、 clean motor and wind wheel, filter and inside of casing.
2 fill the rotating parts with proper amount of smooth oil to ensure the sensitivity and stability of the couplings and bearings.
3, cut off the main power supply, do the corresponding marking, check whether the motor grounding wire is good.
4. Check and change the gasket and seal between the joints.
5, check the local screws and shafts, and fasten.
6, check the mechanical valve opening and closing action can be firm and sensitive, open and close angle mark clear.
7。 Check whether the insulation resistance of the motor fits the rules and check the main circuit contacts。 If the contact is severely ablated (1/3 of the contact point is worn to the original thickness), the contact shall be changed。
8, adjust the tightness of the belt, fire smoke exhaust fan, use the hand wheel to move the wind wheel, see whether the rotation or not.
The 9。 section after the combination of the 45 degree angle trimming external joint, aluminum foil sealing tape to an outer surface of each side plate, a width of not less than 20mm。 square, steel tape to check and adjust the verticality and diagonal bias, and in accordance with the standard request;
10. aluminum foil insulation special adhesive binder used according to the manufacturer identification plate of wind pipe, such as separately purchase brand adhesives, must do the convergence effect contrast experiment, and the supervision and inspection, Accreditation Board business before use;
11. the wind pipe of the arc surface or broken line to complete the material and fold, forming, should be combined with the flat plate, after the error in brushing adhesive, in order to ensure the geometry, size and appearance of the pipe.
Ji'nan smoke hood has a strict working attitude, skilled work skills, will ensure that the task is accurate and efficient completion.
