There Are Some Attentions to Use Pulsar Speedometer Better

Jun 04,2021

   The pulsar speedometer and mileage are integrated, and the common faults and adjustment methods are as follows.
  1. The cause of this type of failure is usually that the speedometer flexible shaft or casing is bent, and the flexible shaft is scratched with the casing when it is rotating; the bearing of the speedometer speed dial shaft is worn and loose, which can also cause the pointer to swing during operation.
   When performing fault detection, first remove the flexible shaft and casing to check whether the casing is bent or flattened. If the above phenomenon occurs, it should be repaired or replaced depending on the degree of damage. If the casing is in good condition, pull out the flexible shaft, hold its two ends, make the middle part sag, and turn the hose by hand. If there is a big lift in the middle part, it means that the flexible shaft is bent and needs to be replaced with a new one. If the flexible shaft and casing are normal after the above inspection, the speedometer should be disassembled, and the speed plate bearing should be checked. If the bushing is found to be worn, it should be replaced.
   2. Speedometer pointer does not move
This type of failure may be caused by two conditions. One is that the speedometer itself is normal, and the failure is in the transmission part of the speedometer, which may be the speed dial shaft is broken, the shaft end is severely worn or the speedometer hairspring is damaged; the second is the odometer drum does not turn , Indicating that the driving parts of the speedometer and odometer are damaged, usually the flexible shaft is broken or the driving gear is damaged. After further disassembly and inspection, the damaged parts should be replaced.
   3. The speedometer is working normally but the word drum of the meter does not turn
   This failure indicates that the transmission gear from the speedometer drive shaft to the first word drum is damaged and cannot drive the word drum to rotate. It should be disassembled and inspected, and the damaged word drum gear should be replaced.
  4. The magnetic degeneration of the magnet in the magnetic speedometer will cause the pointer indication value to be inaccurate, and the magnet should be replaced.
