Generally speaking, the use of emergency stop switch depends on what brand you buy, and then the corresponding instructions, which will talk about the overview, structure, main technical parameters, installation and use, precautions of emergency stop switch. Such as mine intrinsically safe emergency stop switch (hereinafter referred to as emergency stop switch),
Installation and use: 1 Users can choose 3× 1.5 connection of rubber sheathed cable for mining according to their needs, and the distance from the host is ≤1000 m. Using rubber sheathed cable for mine, its distributed capacitance is less than 0. 1μF/km, and its distributed inductance is less than 1mH/km. 2 Install emergency stop switches along the belt conveyor, and connect the action pieces of two adjacent emergency stop switches with iron wire (steel wire rope). 3 When the belt conveyor has an accident, the connecting wire (steel wire) can be pulled at any position to realize the emergency stop of the belt conveyor in case of an accident. At the same time, locking is realized. After the accident of belt conveyor is relieved, it must be manually reset and unlocked before the emergency stop switch can return to normal state.

The emergency stop switch is one of the main control devices. When the machine is in a dangerous state, cut off the power supply through the emergency stop switch to stop the operation of the equipment, so as to protect personal and equipment safety. The "emergency stop switch" is usually a manually controlled push switch (the key is red), which is connected in series with the control circuit of the equipment, and is used to directly disconnect the power supply of the control circuit in case of emergency, so as to make the equipment stop quickly and avoid abnormal work. The general form of emergency stop switch is to press the button switch to lock and rotate to release the red mushroom head or round button switch. Some emergency stop switches are equipped with led lights for easy operation, such as φ 30 emergency stop switch with LED lights in Kaikun, South Korea.
Classification of emergency stop switches: mainly divided into two categories: manual and automatic (through electrical interlocking or mechanical interlocking). Emergency stop switch access circuit: 1. The two contacts at the bottom correspond to the control loop; 2.？ 380V connection: When the power supply A is connected, stop any contact → stop the other point from connecting to a certain point of the control circuit → connect the other point of the control circuit to the power supply B phase. If not, don't move the lead of the emergency stop switch. The two points of the control circuit are interchanged, and some contactors have different directions; 3.？ 220V wiring: the live wire is connected to any contact → another point is connected to a certain point of the control circuit → the other point of the control circuit is connected to the zero line.
Influence of frequent use of emergency switch on equipment: Frequent use of emergency switch is generally harmful to equipment, and emergency stop is only used in emergencies. After the equipment stops normally, some cooling systems have to run for a period of time, and the power supply of the equipment is cut off in an emergency stop. The temperature is higher when stopping for a period of time than when running, which is also the reason why restarting after normal stopping sometimes breaks down.
Precautions in the use of emergency stop button switch: In industrial safety, all machines whose transmission parts will directly or indirectly harm human body under abnormal conditions must be protected, and emergency stop button is one of them. Therefore, when designing some machines with transmission parts, the function of emergency stop button must be added. Moreover, it should be set on the surface of the machine where people can press it conveniently, and there should be no obstacles. Press the emergency stop button switch directly to quickly stop the whole equipment or release some transmission parts. If you want to start the device again, you must release this button, that is, as long as you rotate it clockwise for about 45 degrees and then release it, the pressed part will pop up. It is also "release". The above content introduces the matters needing attention in the use of the emergency stop button switch, hoping to help everyone.
The use of emergency stop switch is not a special refuge. In fact, there are many times related to the emergency stop switch. The definition, classification, use, precautions and influence on equipment of the emergency stop switch are mentioned above. Is there any introduction, such as brand, specification, price, model, the difference between emergency switch and panic button, etc. So please continue to pay attention to Tuba rabbit and introduce more relevant knowledge to everyone, so stay tuned!
