Pre-cleaning
The workpieces shall be checked and cleaned manually to remove accumulated oil, rust, debris, etc. This process only includes lighting and operation tower, without other equipment.
Torrent washing
Function: wash off the iron powder attached to the workpiece surface.
Normal temperature water is used for spraying, with spraying pressure of 0.1~0.2MPa and flow of 600~800L/min.
Pre-degreasing
Pre-degreasing is a process of heating solution for soaking and spraying. It is composed of chamber, tank, spray circulating pump, oil-water separator, heat exchanger in tank, burner, nozzle, valve, piping, etc.
The tank liquid temperature is 45~60 ℃, and the spraying pressure is 0.2MPa.
Water washing tank
Water washing tank is a process of soaking and spraying. It is composed of chamber, tank, spray circulating pump, nozzle, valve, piping, etc.
Surface adjustment groove
The meter regulating tank is a process for soaking and spraying. It is composed of chamber, tank, spray circulating pump, nozzle, valve, piping, etc.
Phosphating
The device consists of chamber, serrated groove, circulating pump, heat exchange pump, slag removal system, heat exchanger, nozzle, valve
