Product Description

Brief introduction to high temperature resistant travel switch:

Heat stroke switch is mainly used for AC 50HZ/60HZ, 380V, DC 220V and the following high temperature and heat environment of the electric line, for motion mechanism of the stroke control, motion direction or speed of the transformation, automatic control of machine tools, motion control and control or program. High temperature resistant switch inside the high temperature resistant material cast into the full closed contact switch, a group of normally open a group of normally closed maximum allowable current 220V 5A/AC, contact after special treatment can be used in high temperature environment for a long time without oxidation or pollution and lead to damage. The maximum temperature is 350. Installation size is 58.7+30.2. Widely used in electric power, chemical, petroleum, textile, steel and other industries.

Heat stroke switch - purpose


 

Heat stroke switch is mainly used for the mechanical displacement into electrical signal, so that the motor running state can be changed, so as to control the mechanical action or used as a program control. High temperature resistant travel switch real handy is in industry, where it and other equipment, composed of more complex automation equipment. Iron and steel, cement, chemical plants have many such resistance to high temperature trip switch, it is used to control the movement of the workpiece or automatic feed stroke, to avoid collision. Sometimes the use of a stroke switch to the controlled object in the specified position between the two automatic change, so as to get constant and reciprocating movement. Always go on like this, it becomes a set of automatic production line, need not tube, working day and night, save the manual labor.

 

Stroke switch - high temperature travel switch

 


 

According to the structure of the travel switch symbol high temperature switch according to its structure can be divided into straight type, roller type, and combination type.

Straight type heat stroke switch:

Tutu 1





 

Action principle is similar to the button, the difference is: one is manual, the other is a moving part of the collision. When the impact of the external moving parts on the touch press button to make the contact action, when the moving parts left, in the role of the spring, the contact is automatically reset. Its structure principle is shown in Figure 1, the action principle and the button switch are same, but the speed of the contact of the contact depends on the speed of the production machinery, and is not suitable for the speed of the 0.4m/min. The straight type high temperature switch is composed of 1: putting 2&4: spring 3: dynamic contact 5: contact

Roller type high temperature travel switch

Tutu 2

 





 

When the movement machinery of the iron (Bump) press to the high temperature of the travel switch on the roller, the drive rod together with the rotating shaft to rotate, so that the cam to push against the block, when the bump into a certain position, to promote the rapid motion of the micro switch. When the roller is removed, the reset spring will be reset to the high temperature switch. This is a single round automatic recovery type high temperature travel switch. And double rotary resistance to high temperature limit switch can not automatically recover, it is rely on mechanical motion moving in opposite directions, block iron collision another roller will be the restoration. The structure principle is shown in Figure 2, when the impact of the controlled machine on the impact of the roller, the impact of the rod to the right, to drive the cam to rotate, push the rod, so that the micro switch in the contact rapid action. When the motion machine returns, the action of the reset spring is reset. Roller type travel switch 1: roller, a rotating arm 3&5&11: spring 4: 6 sets: pulley 7: plate 8&9: contact of 10: horizontal plate

Roller type resistance to high temperature limit switch is divided into single roller automatic reset and double roller (horn) non automatic reset and double roller line shift switch has two stable positions, "memory" effect, in some cases can simplify the circuit.

 

NH high temperature resistant travel mode operation mode:

 1:NHY1 resistant high temperature trip switch handle roller arm type, through the collision trip handle roller arm, the roller arm to the left or to the right swing, so as to make the switch contact action and the realization of circuit switching.


 

 2:NHY2 resistant high temperature limit switch for regulating handle roller arm type, through the collision trip handle roller arm, so that the roller arm to the left or to the right swing, so as to make the switch contact action and the realization of circuit switching, the handle roller arm can adjust the roller length, which can reach the collision switch.


 

3:NHD1 high temperature travel switch for the top of the cylinder, through the impact of the upper part of the cylinder, so that the cylinder to press down, so that the switch of the contact action to achieve circuit switching.


 

 4:NHD2 high temperature travel switch for the roller (horizontal) plunger type, through the impact of the top of the trip to the roller, so that the roller pressure, so that the switch of the contact action and achieve the circuit switch.



 

5:NHL1 resistant high temperature trip switch for adjusting rod type, collision trip through adjusting rod, round bar to the left or to the right swing, so that the contact of the switch of the act and the realization of circuit switching, can adjust the length of the rods to achieve collision length.


 

 6:NHYY resistant high temperature limit switch for dual limit switch has ot large angle type or cross type pendulum rod locking type, to make the roller arm to swing through the collision trip handle roller arm, the roller arm lock on the right, so that the contact of the switch of the act and the realization of circuit switching.


 

 7: Heat stroke switch NHD3 for the ball of the ball, through the collision of the top of the ball, so that the ball down, so that the switch of the contact action to achieve circuit switching.

 
 

8:Resistant high temperature limit switch NHD21 roller (vertical) plunger type, through the collision trip on top of roller, roller press down, so that the contact of the switch of the act and the realization of circuit switching.


 

 9:High temperature resistant switch NHA5 for universal spring type, through the impact of the stroke of the spring, so that the spring can move in any direction, so that the switch of the contact action and achieve circuit switching.



 

Heat stroke switch - note

High temperature switch in use should pay attention to the problem (1) in the installation of high temperature switch, to check whether the iron in the travel in place of the impact of travel switch head, must not be a collision in the middle or other parts of the trip switch. (2) in the installation or in were examined for resistance to high temperature trip switch to fix it firmly, and with slide hand or dynamic pressure high temperature limit switch action head, listen carefully, check whether there is the sound of "bang", if there is no should be open resistance to high temperature limit switch, regulation connecting the micro switch and the movement axis of the screw.
