Lasc Stróc Stróc Teorainn Brú Féin-Athsholáthair

The travel limit switch is triggered mechanically, and the action of the contacts is used for control: when the moving parts of the equipment move to a preset position and touch the triggering mechanism of the switch (such as a roller or lever), it drives the internal mechanical structure to interact, causing the normally open/normally closed contacts of the switch to switch between on and off, thereby cutting off or connecting the control circuit to realize the start and stop of the equipment, limit protection, nó athrú próisis.

I dtrealamh ar nós deileanna, meaisíní muilleoireachta, agus ionaid mheaisínithe, suiteáiltear lasca teorann go coitianta ag an dá cheann den treoir -iarnród nó ag suíomhanna foircneacha an tábla sleamhnáin. Mar shampla, ar shealbhóir na n -uirlisí ag gluaiseacht rian de dheil CNC, nuair a théann an sealbhóir uirlisí i ngleic le deireadh an rian, spreagtar an lasc chun an chumhacht mhótair a ghearradh amach, rud a choisceann sealbhóir na n -uirlisí dul thar a thaisteal agus imbhualadh leis an gcomhlacht meaisín. Ar an gcaoi chéanna, nuair a ghluaiseann an tábla oibre den mheaisín muilleoireachta ar an taobh nó ar ais agus amach, rialaíonn an lasc na teorainneacha gluaiseachta go cruinn, ag cur cosc ​​ar chur isteach idir na comhpháirteanna oibre agus na comhpháirteanna meaisín, rud a chosnaíonn an uirlis ghearrtha agus ag cinntiú cruinneas meaisínithe.
