The Technobell’s tank production equipment is designed to produce Glass Reinforced Polyester (GRP) tanks, both horizontal and vertical, for below- and above- ground applications, from GRP pipes produced on the Continuous Filament Winding (CFW) production line.
The equipment enables the production of GRP tank diameters from 1000 mm to 3000 mm with the capacity from 1 m3 to 81 m3 depending on cylinder/pipe length.
Tanks are made from GRP pipes produced on a continuous filament winding (CFW) production line and reinforced with parallel and/or cross-filament winding of roving impregnated with resin.
The tank cylinder (GRP pipe) is transferred to the motorised support and it is assembled with end caps using internal joining rings. End-caps are then fixed to the cylinder by applying roving impregnated with resin. The cylinder reinforcement process is then carried out on a dedicated winding machine and performed with synchronisation of tank rotation speed and a horizontally moving carriage delivering raw materials.
At the end of the self-curing process, the tank is ready for installation of any required connectors and/or fittings.
Tank filament winding machine (TFW)
The manufacturing of tanks is done with synchronizing relative speeds of tank rotation and horizontally moving carriage equipped with raw materials. The laminate building–up can be easily made in compliance with the appropriate design. The TFW Machine is digitally controlled. All machine operations and the dosing system are controlled by computer. Production data are stored and available on the machine.
Cross support (CRO)
The CRO simplifies the placing of the ring inside the base of the shell, because the base is not circular. The CRO is composed of four telescopic arms with pins, for different diameters of tanks. Two sections are equipped with push spanners and two with adjustable legs.
Flat end cap mould (FLM)
The FLM equipment is designed for the production of GRP tank flat end caps. The flat end cap is constructed by hand lay-up and spray-up on the FLM and is extracted with compressed air.
Semi-ellipsoidal end cap mould (SEM)
The SEM part is designed for production of GRP tank semi-ellipsoidal end caps. The semi-ellipsoidal GRP end cap constructed by hand lay-up and spray-up on the SEM and is extracted with compressed air.
Joining ring (JRI)
The JRI set is designed for joining tank end caps with the shell of tank, before filament winding is undertaken on the TFW machine. The JRI is equipped with two tensioners for adjusting circularity and diameter. The same ring is used for joining flat or semi-ellipsoidal end caps.
Spider (SPI)
The SPI is installed and laminated on the flat or semi-ellipsoidal cap end with polyester resin and glass fibre. The tank with SPI on both sides is positioned on MSU machine where the joints lamination between the cylinder and cap ends is carried out. After that the TFW machine is used to reinforce the tank structure in accordance with project design specifications.
Motorized support machine (MSU)
The MSU machine rotates the tank during the laminating of the joint between the cylinder and the end caps, using a spray-up machine for applying cut-glass fibres and polyester resin.
Carriage support (CRS)
The CRS is used to support or transport tanks during the various phases of production and for various diameters, utilising appropriately sized metal inserts.
