HOMOLOGATION AND INSTALLATION
Homologation
- Complies with CEI- EN 60947-5-1 standards.
Installation and use- Flange connection suitable for horizontal and vertical installation.
- It is recommended to install ASE away from storages loading places and away from the presence of materials with high specific gravity, protecting by a reflective device the shaft and the propeller.
MAXIMUM LEVEL
- Device installation usually is carried out on the head side of the tank.
MINIMUM AND MEDIUM LEVEL
- Usually, the device is mounted horizontally.
- For small tanks, extending axle you can mount as well on the head side.
- For lightweight materials and fluids are used screws with large blades. For large sizes materials are required screws with flexible blades.
- Elements, that determine the operation are the synchronous motor and its torque.
- The material impedes propeller rotation to a stop.
- Suitable to control materials (such as granules and powders) with a specific gravity of approximately 0,7 kg/dm³.
- When the material hampers the screw rotation, the electric motor with the force of its torque acts on the microswitch, which closes or opens the electrical circuit (24 ÷ 280Vac 10A) while the second microswitch shuts down the motor disconnecting the power supply.
- Reducing the level, the propeller is released and through the return spring the motor and microswitches automatically pass into the initial position.
- N.B. If you want to use for control a second microswitch, used voltage should be the same with motor’s supply voltage.
