How to install large motor housings

Large motor housings installation method:
1, the anchor screw installation
Tighten the screw to anchor slab with gasoline and other solvents clean, and check the thread for disorderly clasp and touch bad place, with nuts trying a twist. Also measure the actual length of the holes of anchor bolts and check the length of the screw is appropriate. Anchor plate should closely based on post, the anchor screw should be vertical plate with anchor. The anchor screw the most commonly used is double and no screw, installation is more convenient, also made the crowd with a screw, this type of structure from the screw down, and put the screw in the anchor plate one glyph hole, and then turn 900 screw is the anchor plate to lock. The anchor to tighten the screw before, should be in threads grease in advance.
2, the floor installation
Big motor of the floor, general is welded by steel plate, or by beams and compound channel steel and other and become.
Motor of the floor with a whole, also have partition. Their action is supporting motor, and the electric motor and the static load transfer to the base, and keep the motor and part of the installation size and gap remains the same.
1 and base before installation should be free from oil, grease, remove the antirust paint. Especially in the combination of cement and water surface, want to use in addition to paint and steel brush is swabbed clean, and dried with a cloth, best can advance a coat of slurry.
2 in cleaning the floor, must pay attention to the mounting surface bearing the stator and installation face whether there are wounds standby or corrosion, such as the discovery of a similar defects file and sand paper application changed.
3, a new installation motor for basic bottom to have firm demand, should be enough solid foundation and under certain static load and dynamic load cases, foundation should not produce sink. To prevent motor foundation sink, generally in the foundation to pour out after preloading, preloading weight usually motor installed weight of 1.5 ~ 2.5 times. In the process of continuous pressure measurement elevation, sinking observation, to stop the ability after sinking foundation for installation. For example a steel mill in early 1150 when the motor installed on basis of preloading, preloading weight for the total weight of motor 2 times or so, after 48 hours after the foundation sink for 2 mm
