4.State-of-the-art screw element, original air end.

Use of emergency stop switch on air compressor

The emergency stop switch for the air compressor is also used to instantly disconnect the power supply when the machine fails, but most of us use it for debugging and maintenance. The emergency stop switch is a common switch, which is needed in many equipment and facilities. It is a kind of master control electrical appliances. When the machine is in a dangerous state, the emergency stop switch cuts off the power supply to stop the operation of the equipment to achieve protection. Personal and equipment safety. types of air compressor

Then the emergency stop button contacts on general equipment use normally open contacts and some use normally closed contacts. Therefore, people often ask whether the emergency stop button should use a normally closed contact or a normally open contact. In my opinion, in the design, it is necessary to use normally closed contacts as much as possible when using emergency stop.

Let's take a look at the specific analysis: the time for the normally closed contact of the emergency stop switch to be closed to open is much shorter than the time for the normally open contact to be closed from the natural state. Maybe you want to say, how can it be so much less? Such a short time does not matter. But I want to say that this is especially important when an emergency stop is needed in the event of danger. At this time, no matter how short the time is, even milliseconds or even microseconds are very important. You know, the accident happened in a short period of time. You can think about it, in such a short period of time, you may not stop the machine or open the switch by using the normally open contact, causing major machine damage or personal injury. However, the use of normally closed contacts may stop the machine or make people get an electric shock for a shorter time, avoiding all this from happening. types of air compressor

We know that whether the emergency stop button is a normally closed or normally open contact, if it is not pressed in place (press to the end), it will bounce again, which will invalidate the action. When using normally open contacts, when the emergency stop button is not pressed in place, the emergency stop has no effect (because the normally open contacts are not closed); when using normally closed contacts, it is different, regardless of emergency stop The button is not pressed in place, only the contact is activated, and the emergency stop will work. types of air compressor

Needless to say, the most basic function of the emergency stop button is to stop in an emergency to avoid mechanical accidents or personal accidents. However, due to the long-term operation of the machine, the line, especially the part of the emergency stop line, may cause a fault and open circuit. At this time, if the emergency stop button uses a normally open contact, the line fault of the emergency stop part will not be found. If the emergency stop button is used then it will be too late.

When using normally closed contacts, when the emergency stop part of the line fails, z* will cause the machine to stop, and the loss will be relatively small. When designing the electrical control system, the emergency stop button z* is better to use normally closed contacts, so that the safety factor is relatively high. types of air compressor
