What are the safety protection devices of the high speed door？
high speed door with heat preservation, collision, insect, wind, dust, sound insulation and other characteristics, can realize the rapid operation of opening and closing the door, so it is widely used in the production space of strict environmental requirements, like food, electronic workshop, printing and packaging, chemical, pharmaceutical, dust-free workshop, logistics warehousing and other places.
Some people will have questions? Can the high speed door ensure the safety of people or things?
In fact, the high speed door has four kinds of safety protection devices: emergency stop button, safety bottom edge device, photoelectric protection device and safety light curtain device.
1. Emergency stop button
When the emergency stop button is pressed, a pair of contacts to cut off the door curtains need to run the power equipment, another pair of contacts into the PLC, cut off by the PLC control of the power equipment starting circuit.
2. Bottom airbag device
By the receiving end of the device and the transmitting end of the device, the transmitting end of the device to control the air pressure switch and send the circuit, the installation of the airbag bottom seal triggers the air pressure switch in the high speed door body under the curtain, in the door body down, such as touching someone or an obstacle, the high speed door body will immediately stop to the downward spiral, automatically and reverse run up to the top. After removing the object, the door will descend automatically, this function is effective in both manual and automatic, to ensure the safety of people and car traffic.
3. Photoelectric protection device
High speed door with reflective photoelectric switch, sensor range 0-5 meters installed on both sides of the door column, the height of 30 to 40 centimeters. Door running automatically down, someone or an object blocking the sensor, the door will immediately stop falling, automatically rise to the top. When the object is removed, the door will automatically fall to the bottom. It is effective in both automatic and manual operation.
4. Safety light curtain device
High speed door safety light curtain device is very suitable for the use of high-frequency enterprises, because the contact area of this device than the safety of photoelectricity is much larger than the door frame on both sides of the light curtain direct a sensor light, just trigger to any one of them, the door of the high speed door will immediately terminate the operation, the immediate rise, security is relatively high.
The above is the introduction of the four common safety protection devices of the high speed door, manufacturers in the choice of high speed door, according to the actual working conditions of the factory site to select the corresponding safety protection devices.
