Emergency stop switch usage, it is not difficult to read!

Emergency stop switch usage, according to my understanding, the emergency stop switch belongs to the main control electrical type, there is a physical class related knowledge. To know how to use the emergency stop switch, you need to know what is the emergency stop switch, even the emergency stop switch instructions need to be carefully read, in the use of the emergency stop switch should pay attention to the matters to be borne in mind, so that we can do safety without hidden danger. For the use of the emergency stop switch, it is not difficult to use, in the emergency stop switch with the corresponding red indicator, so do not need to worry about, the following I specifically for you.

The use of the emergency stop switch, in general, depends on what brand you buy, and then look at the corresponding manual, the manual will talk about the overview of the emergency stop switch, the structure, the main technical parameters, installation and use as well as precautions. For example, mining intrinsically safe emergency stop switch (hereinafter referred to as emergency stop switch),

Installation and use: 1 users can choose according to the need for mining rubber cable 3 × 1.5 wiring, and the distance from the host ≤ 1000m, the use of mining rubber cable, the distribution of capacitance is less than 0.1 μF/km, the distribution of inductance is less than 1mH/km. 2 along the belt conveyor to install the emergency stop switch, and the two adjacent The action pull ring of the emergency stop switch is connected with wire (steel wire rope).3 When the belt conveyor has an accident, the connecting wire (steel wire) can be pulled with force at any position to realize the emergency stop of the belt conveyor in case of accident and realize locking at the same time.4 The belt conveyor has a capacitance of less than 1mH/km and a distributed inductance of less than 1mH/km. At the same time, it can realize locking.4 After the belt conveyor accident is lifted, it must be unlocked after manual reset, and the emergency stop switch can be restored to the normal state.

Users can choose mining rubber cable 3×1.5 wiring according to the need, and the distance from the host ≤1000m, using mining rubber cable, its distribution capacitance is less than 0.1μF/km, distribution inductance is less than 1mH/km.4.2 Install the emergency stop switch along the belt conveyor, and connect the action pulling ring of the two neighboring emergency stop switches with iron wire (steel wire rope).4.3 When the accident occurs on the belt conveyor, the connecting wire (steel wire) can be pulled with force at any position to realize the emergency stop in case of accident on the belt conveyor. At the same time realize the locking.4.4 After the belt conveyor accident is lifted it must be unlocked after manual reset before the emergency stop switch can return to normal state.?

At the same time realize the locking.4.4 After the belt conveyor accident is lifted it must be unlocked after manual reset before the emergency stop switch can return to normal state.?

Emergency stop switch" is usually a manually controlled push switch (button is red), series access to the control circuit of the equipment, used in emergencies to directly disconnect the control circuit power supply to quickly stop the equipment to avoid abnormal operation.　The general form of emergency stop switch is pressed to lock the rotary release of the red mushroom head button switch or round button switch, there are also emergency stop switch in order to facilitate the operation of the LED lights added, such as South Korea's Kaikun Φ30 with led lights emergency stop switch.

Categorization of the emergency stop switch: mainly divided into two categories, manual, automatic (by electrical interlock or mechanical interlock).　Emergency stop switch access circuit: 1.? The two contacts at the bottom correspond to the control circuit; 2.?380V connection: power supply A phase connects to either contact of the emergency stop→another point of the emergency stop connects to a certain point of the control circuit→another point of the control circuit connects to the power supply B phase. If you can not work, the emergency stop switch leads do not move, the control circuit of the two points of the swap, some contactors have direction difference; 3. 220V connection: firewire to emergency stop any contact → emergency stop another point to a point in the control circuit → control circuit another point to the zero line.

Frequent use of emergency stop switch on the impact of equipment: often try emergency switch is generally harmful to the equipment, emergency stop only in the event of an emergency to use. After the normal shutdown of equipment, some cooling systems have to run for a period of time, the emergency stop the equipment power supply are cut off. A section of the moment just stopped that the temperature is higher than when running, which is why sometimes after a normal shutdown and then open the reason for the bad.

Precautions for the use of the emergency stop button switch: in the industrial safety requirements where some of the transmission parts will be directly or indirectly in the event of anomalies in the human body will be harmed by the machine must be protected, the emergency stop button is one of them. Therefore, in the design of some machines with transmission parts must be added to the emergency stop button function. And to be set in the personnel can be easily pressed on the surface of the machine, there can not be any obstruction. Emergency stop button switch, just directly downward pressure, you can quickly make the whole equipment immediately stop or release some transmission parts. To start the machine again, the button must be released, i.e. by turning it clockwise by approximately 45° and then releasing it, the pressed part will spring up. That is, the pressed part will pop up, i.e. "release". The above content describes the emergency stop button switch to use the precautions, I hope to help you use.

The use of the emergency stop switch is not a special refuge, about the emergency stop switch related to the time in fact, especially more, the above on the definition of the emergency stop switch, classification, use, precautions, and the emergency stop switch on the equipment and other impact. We also have parts that have not been introduced, such as the brand of the emergency stop switch, the specifications of the emergency stop switch, the price of the emergency stop switch, the model of the emergency stop switch, the difference between the emergency stop switch and the emergency stop button and so on.
