Fixed Water-Based Local Application Fire-Fighting System RDFF Fixed Water-Based Local Application Fire-Fighting System is a modern marine fire fighting product developed in accordance with SOLAS regulation II-2/10.5.6. It has characteristics of quick startup, good fire fighting and low water consumption. And it can extinguish or control fire on time without engine shut down, personnel evacuation, shutting down of forced ventilation fans or sealing of the space. Its mainly used in the place where high fire danger, quick spreading speed, bad fire effect and hard extinguishing.Immediate inquiry Feature: - 1.5L/min per 2m water discharge capacity, so that the potential water damage is reduced to a minimum, - The durative of fire-extinguishing is very long since the easy water source, - Efficaciously control the fire and its very fine droplets of water spray prevent heat extending, - Efficaciously extinguish the liquid fire which is a kind of lower flash point, - Supply the main alarm panel with the processing PLC or PCB, - Type approval: CCS, LR, EC.

Adjustable Speed Permanent Magnet Eddy Current Transmission Working principle: Generally copper rotor (Steel rotor with copper ring) connect with motor shaft, permanent magnet rotor (aluminum rotor with permanent magnets) connect with load shaft. There is only a air-gap between copper rotor and permanent magnet rotor without mechanical connection for transmition the torque. When the motor rotates, the copper ring of copper rotor cut the magnetic field lines of permanent magnet, generate inductive eddy current and creates a magnetic field in copper rotor, thereby transmitting torque across the air-gap. Smaller air-gap, stronger the force of transmitted torque. Otherwise, weaker the force of transmitted torque. Vary the air-gap spacing by actuator component which is operated by hand or automatic control system. Technical advantage: Few day-maintenance,low operation cost, almost maintenance-free products. Accept misalignment, the error of centration 5mm (max). With overload protection function, so as to improve the safety, the reliability of the whole system,completely eliminate the damage to the system caused by overload. The device is with soft starting performance in order to improves motor starting capability, soft start.motor or soft stop. Besides,reduce the motor start instantly on impact and vibration equipment. For the special structure, the vibrating is not passed between motor and the device in order to effectively reduces the system vibration and prolong the service life of its component. Simple structure, small size, easy to install, adapt to work in harsh conditions. Adjust air-gap for getting required torque and speed with significant energy-saving effect.
Limited Torque Permanent Magnet Eddy Current Transmission Working principle: At the initial position, the air-gap is 3mm between copper rotor and permanent magnet rotor. When the motor rotates, the copper ring of copper rotor cut the magnetic field lines of permanent magnet,generate inductive eddy current and creates a magnetic field in copper rotor. Between the two fields,there is force which is not only transfer torque between the motor and work machine, but also transfer the axial force between sub-rotors. Compared with the speed slip between copper rotor and permanent mangnet rotor, the air-gap is from 3mm to 5mm for achieving better soft-start. When the work machine suddenly overloaded or stuck in the case, the speed of permanent magnet rotor decreased rapidly, or reduce to zero immediately. But, the speed of the motor and the copper rotor almost the same, due to the axial force between sub-rotors enlarge the air-gap till max. Thereby reducing transmitted torque between the copper rotor and the permanent magnet rotor till a small value.And, even the load exceeding a certain limit value, the motor is fully protected Technical advantage: Few day-maintenance,low operation cost, almost maintenance-free products Accept misalignment, centration error 5mm (max), angular error 2 (max) 。 With overload protection, increase overall system reliability, eliminate the damage of system for overload. When the loading is in normal, the system automatically return to working or can be directly re-start. Improve the motor starting capability and come true the motor soft start / stop. Specially, suitable for big torque, high inertia loads. Reduce shock and vibration, coordinate between multi-machine-driven load distribution. Simple structure, small size, easy to install, adapt to work in harsh conditions. Extend the life of the transmission system components.
Standard Type Permanent Magnet Eddy Current Transmission Working principle: Standard Type Permanent Magnet Eddy Current Transmission mainly include the copper rotor,permanent magnet rotor. Generally copper rotor (Steel rotor with copper ring) connect with motor shaft,permanent magnet rotor (aluminum rotor with permanent magnets) connect with load shaft. There is only a air-gap between copper rotor and permanent magnet rotor without mechanical connection for transmission the torque. Technical advantage: Few day-maintenance,low operation cost, almost maintenance-free products Accept misalignment, the error of centration 5mm (max), angular error 2.5 (max) 。 With overload protection, increase overall system reliability, eliminate the damage of system for overload Improve the motor starting capability and come true the motor soft start / stop. And, reduce shock and vibration, coordinate between multi-machine-driven load distribution. Extend the life of the transmission system components. Simple structure, small size, easy to install, adapt to work in harsh conditions. Allowed adjusted the air-gap to achieve the required torque transmission and speed delivery requirements. Supply a variety of special shaft or installation size.
