Common failures of vertical motors
Vertical motor is a motor whose axis line of the output shaft is perpendicular to the chassis or a variable speed mechanism. Its outstanding feature is that the mounting holes are centered on the output shaft and are equally spaced around them. The vertical motor is arranged vertically on the driven machine, and the motor shaft also drives the machine vertically. It is used a lot in industrial production, such as vertical water pumps and vertical lathes. During the use of the motor, the temperature of the motor or the bearing is often too high due to the selection of the bearing and the hidden problems in the matching of the parts and the bearing, which does not meet the requirements of the equipment.
Thrust pad burnout Thrust pad is a key component of a large vertical motor. According to statistics, the thrust pad burning failure accounts for about 40% of the equipment failures of the water pump unit. The fundamental reason is that the oil film layer between the thrust pad and the mirror plate is destroyed, the frictional heat increases rapidly, and the temperature of the tile surface exceeds the melting point of the tile surface babbitt alloy, resulting in burning. The current solutions mainly include: increasing the area of the existing babbitt alloy thrust pad, increasing the overload capacity of the thrust pad, adopting a hydraulic jacking device (opening a hole in the center of the thrust pad, injecting high pressure oil to promote oil film formation), ensuring the thrust head and The machining accuracy of the contact surface between the thrust pads, and the improvement of the cooling capacity of the water cooler in the fuel tank, etc.
