Bearing washing plant

Bearing washing plant Bearing washing plant

Bearing washing plant is designed for washing and drying of roller bearings installed on freight and passenger cars as well to repair wheel sets. The plant is used for new production (degreasing).
The plant for washing and drying bearings consists of the following main components: a tank, a washing and drying chamber, and a control panel. The tank is additionally equipped with a skimmer - a disk device, which allows you to remove the layer of waste lubricant which formed on the surface of the washing solution and discharge it to a separate container.

Operation principle


The plant for washing and drying bearings works as follows: in the initial position, dirty bearings stop on the inlet ramp with a damper. After turning the damper and the operator’s command (or a signal from the plant control system) to turn on the device, an automatic operation cycle starts. The drive of the bearings rotation mechanism in the washing and drying chambers is turned on and the chamber shutters are lowered. The supply system of the washing solution in the washing chamber and the blowing system in the drying chamber are turned on. The duration of the washing solution supply to the washing chamber and air to the drying chamber is set by the operator before starting the operation of the equipment complex. After the washing and drying processes are completed, the chamber shutters are lifted and the bearings are rolled from the washing chamber to the drying chamber, and from the drying chamber to the outfeed chute of the device.

Advantages

  • Timer  (enabling / disabling tubular electric heaters according to a set program);
  • Liquid level sensors with output to the operator's control panel;
  • Automatic water refill;
  • Automatic oil drain tank ;
  • Automatic maintenance of the set fluid temperature.
