The scope of use of the travel switch (limit switch).
The range of use of travel switches (limit switches) is very wide, so what is the effect of travel switches (limit switches)? Travel switch (limit switch) refers to the switch assembled in the electrical shell in order to maintain the micro switch from external force, oil, water, gas, dust and other hazards, especially suitable for places with special requirements for mechanical strength and environmental adaptability, the shape of the limit switch is roughly divided into vertical type, horizontal type, composite type.
Travel switches (limit switches) are used in the control and limit of lifting, transmission machinery and space coordinates in various industries such as ports, construction, and mines. The travel switch (limit switch) is composed of a high-precision and large transmission ratio reducer and an output shaft synchronous mechanical memory control organization and sensor.
The working principle of the travel switch (limit switch).
Limit switches can be divided into touch type and non-touch type according to different methods of use. The touch type is to install a travel switch on the moving parts of the mechanical equipment, and to install the limit azimuth stop at the relative motion fixed point, or the opposite device orientation. When the mechanical contact of the travel switch touches the stopper, it can effectively cut off or change the control circuit, and the machine stops or changes the operation.
Maintenance of travel switches (limit switches).
The most important effect of the travel switch (limit switch) must be its maintenance effect, the limit switch is also known as the travel limit switch, which is mainly used to control the stroke of mechanical equipment and carry out limit maintenance. In practical application, the stroke limit switch device is installed in a pre-arranged position, and when the module installed in the production of mechanical moving parts hits the stroke, the stroke limit switch contact action is used, which is useful to complete the switching between circuits.
Limit switch refers to a kind of circuit electrical appliance that correctly switches according to the travel direction of moving parts, and the effect principle of limit switch is similar to that of a button. It is widely used in all kinds of machine tools, lifting machinery, etc., to control its stroke and carry out terminal limit maintenance.
Everyday use of travel switches (limit switches).
The most important effect of limit switches is the interlocking maintenance of machinery. The most common thing in life is that the limit switch is used in washing machines and tape recorders. When the washing machine is dehydrated, the speed is very high, if the washing machine door or cover is opened due to negligence, the hand is reached, it is easy to form damage to the human body, in order to effectively avoid this kind of incident, most washing machines are equipped with electrical contacts, once the washing machine door or cover is opened, it will actively cut off the power, forcing the rolling parts to stop, and the occurrence of damage is useful to avoid.
Industrial use of travel switches (limit switches).
The effect of the travel switch (limit switch) is also manifested in the industrial field, which is mainly used to convert the mechanical displacement into an electrical signal, so that the running state of the motor can be changed to achieve the control of mechanical action or program control. The real use of the effect of the limit switch is in the industry, and other equipment to form a more complex and scientific automation equipment. The limit switch on the machine tool effectively controls the workpiece movement and active feed stroke to avoid the occurrence of collisions. The limit switch is used to make the controlled object actively reversing between the specified directions to obtain continuous reciprocating motion.

Tianyi switch - the reason why the air switch trips and cannot be pushed
1. What is the reason why the empty trip cannot be pushed?
1. If the air opening itself is faulty or damaged, the air opening should be replaced with a new one.
2. If the line is caused by a short circuit, the line should be found first, and then reconnected.
|
|
Tianyi switch - the air switch is always the reason for tripping
1. The current value of the air switch is too low, and the load power is greater than the rated power of the air switch.
2. The load joint is not firm, and the joint is not compressed.
3. If there is a short circuit in the line, check whether the electrical plug is dry.
4. The line is aging and leaking, resulting in both the live wire and the neutral line.
