Under the control of power failure or falling rod signal, the three-roll gate cross-bar automatically falls, called the falling-bar gate; otherwise, it is called the non-falling gate. The advantage of the automatic falling rod is that in an emergency, the crossbar falls and the barrier passage forms a barrier-free passage, which is beneficial to the rapid evacuation of the crowd; the disadvantage is that the falling rod mechanism often moves, and the "joint" is easily worn to form a fault point. And, after the drop, you need to "up" to work. For the electric three-bar mechanism, the automatic upper rod takes a certain time, the control unit controls the motor to repeatedly adjust, and the mechanism is complicated; for the mechanical movement, it is necessary to manually “lift the rodâ€, and the workload is very large. Therefore, the mechanism of the falling gate is complicated and easy to malfunction. When not necessary, try not to use the drop gate. The off-bar gate can be freely rotated in both directions under the control of power-off or drop-off signal, and can also function as an evacuation.
For small enclosed areas, where there is an emergency evacuation requirement and no other evacuation passages, it is necessary to install a drop gate. Ensure that the gates are dropped when the emergency occurs, and the crowd is quickly evacuated to meet fire safety, such as theaters.
For large enclosed areas, where there is an emergency evacuation requirement, and there are other evacuation channels, the gates can be installed. For example, tourist attractions, entrance gates, export labor, and vehicle access, in an emergency, visitors can evacuate from exits, vehicle passages, etc., there is no need to install the gates.
Liquid Cooling Plate For EV
The liquid cooling plate can be used for EV(electrical vehicle). It is also called water cooled heatsink or aluminum cooling pad. The size and channel can be customized. The size can be very wide and also very tight. During the channel design, we can provide R&D service. For example, we can help to do the thermal simulation or do the all design.
Please feel free to send project informations so that we can work out the good proposals for you. With our strong technical team and experienced sales representatives, we can give quick response for your project.
