The drum washing machines are the best washing solution for the washing of small metal parts.
The drum machines are built in stainless steel AISI 304 sp. 20/10 TIG electro-welded. Inside the drum, on the top, are placed the spraying ramps. The spraying ramps are with quick connections and fixings to extract it easily for their periodic cleaning. The bottom of the treatment sections are connected with the buffer tanks. To ensure an excellent cleaning, the buffer tanks have two sections. The first section is used to filter the solution up to 500 microns and remove contaminants in suspension, the second section is used to spray the detergent, with a low degree of contamination.
The two tanks are connected in a recirculating waterfall.
The first section is supplied with:
- inclined bottom with drain valve,
- inspection cover,
- rock wool insulation,
- gravity separating suspended contaminants,
- Water inlet manual valve,
- 500 micron basket filter in back flow.
The second section is supplied with:
- process pump and piping,
- inclined bottom with drain valve,
- 03 float level controls (min., max. refill),
- heating elements,
- automatic refill with electro-valve,
- rock wool insulation,
- inspection cover.
The drying is obtained through a continuous flow of air. The recirculation of the air is produced with electric fan with high flow and prevalence. The heating of the air is obtained through electrical heaters for air built with finned pipe.
The conveyor is driven by a motor with speed controlled by inverter. The slow rotation speed allows a continuous movement of the parts under the sprays nozzles, this tumbling action ensuring that all areas of the product are cleaned to a high standard.
The electrical cabinet is equipped with one or more frontal doors. Insulation IP 55 class according to the law EN 60529. The board has an inside hinged door and mechanically interlocked in case of tension. Inside the board the used room will be less than 75%. The power electric peripherals and the guards will be placed inside the control box in a position easy to access and identify the single components.
The working tension power will be of 400/230 Volts 50 Hz. three-phases for a current value equal to 30% more than that rated. Each engine unit will be protected by a suitable switch gear and magnetic starter with overload and under voltage protection. Each element unit will be protected with fuses and remote control switch opportunely dimensioned. The devices are SIEMENS and TELEMECANIQUE type, or similar. The starting of any device will be by commands set on 24 Volts auxiliaries circuits fed by transformers.
The panel can be equipped with PLC and operator panel touch-screen (optional)
