Solution to the speed-regulating steel ball falling off: Remove the gear chamber cover, take off the three thrust bearings on the speed-regulating slide plate, and use 1 mm thick cardboard to make a circular gasket with the same size and shape. Just like the thrust bearing, place it between the sliding plate and the bearing to troubleshoot.

Single-cylinder air-cooled diesel engines are deeply loved by users due to their light weight, small size, simple structure and easy maintenance, and are widely used as supporting power for micro tillage machines. However, compared with water-cooled diesel engines, they appear to be particularly "delicate", suffer from high frequency of improper use and low reliability.

Notes

During the thunderstorm season, if the lightning protection effect of the entire workshop power grid is not good, strong lightning strikes will cause the power grid to be unstable and prone to thyristor failure. Module breakdown and fuse burnout are particularly serious in high-power DC speed regulators.

Therefore, ensuring the stability of the power supply grid is the basic condition for the stable operation of DC speed regulation. If there is a strong thunderstorm or the power grid is unstable, it is best to temporarily stop using the equipment and put it back into use after the grid is stable. .

Since the start of the press is a heavy-load start, the motor cannot be started frequently. The number of times should be limited to no more than 4 times per hour. When the machine tool is powered off, the main motor must be stopped first and wait for the main motor to start. After stopping, cut off the power.

Only certified and qualified personnel (who have knowledge about rectifiers and understand the content of the information provided) can engage in the installation, startup, operation, troubleshooting or repair of rectifiers.

After the power supply is disconnected, the snubber capacitors continue to carry dangerous voltages. For this reason, the rectifier must not be opened for at least 2 minutes after the rectifier has been switched off.

In order to avoid arcing and the irreversible damage caused by it, the rectifier must be thoroughly protected from the dust inlet, depending on the pollution level, dust and foreign objects, especially pollutants brought in by the cooling air flow It must be cleaned regularly, at least once a year, and the rectifier must be cleaned with dry compressed air, with a maximum pressure of 1 bar.
