What should I pay attention to when installing the y-series three-phase asynchronous motor? How w to start for the first time installer?
First, determine the motor installation site and installation foundation
The installation site elevation of the motor shall not exceed 100()m; General use of the installation site of the motor to be dry, clean, around the motor should be well ventilated, and other equipment should have a certain interval, in order to facilitate inspection, monitoring and cleaning, environmental temperature below 40 ℃, and prevent the intense radiation; The installation foundation shall be firm and firm with a certain stiffness. The installation surface shall be flat to ensure the balanced operation of the motor.
What should be prepared before installation
Should check whether the packaging is intact before opening the motor, the phenomenon of presence of be affected with damp be affected with damp, after the open cover shall be careful to clear the dust and rust layer on the motor, carefully check the presence of deformation and damage in transit, have fasteners loose or fall off, the rotor rotation is flexible, nameplate data meets the requirement, using 500 VMQ table measuring high pressure resistance, insulation resistance shall be not less than 1 mq or dry processing should be made for winding but processing temperature not to exceed j-20 ℃.
In addition, when coupling connection, the motor shaft center line and the load machinery shaft center line to coincide, so as to avoid the motor in the movement of strong vibration, shaft movement and abnormal sound. The installation deviation of the device is 0.015mm for 2-pole motor and 0.04mm for 4-pole motor and 8-pole motor.
