800T-N50LGGGG产品详情
限位开关就是用以限定机械设备的运动****限位置的电气开关。限位开关有接触式的和非接触式的。接触式的比较直观,机械设备的运动部件上,安装上行程开关,与其相对运动的固*上安装****限位置的挡块,或者是相反安装位置。当行程开关的机械触头碰上挡块时,切断了(或改变了)控制电路,机械就停止运行或改变运行。由于机械的惯性运动,这种行程开关有一定的“超行程”以保护开关不受损坏。非接触式的形式很多,常见的有干簧管、光电式、感应式等,这几种形式在电梯中都能够见到。当然还有更多的****形式。限位开关是一种常用的小电流主令电器。利用生产机械运动部件的碰撞使其触头动作来实现接通或分断控制电路,达到一定的控制目的。通常,这类开关被用来限制机械运动的位置或行程,使运动机械按一*置或行程自动停止、反向运动、变速运动或自动往返运动等。在电气控制系统中,限位开关的作用是实现顺序控制、*控制和位置状态的检测。用于控制机械设备的行程及限位保护。构造:由操作头、触点系统和外壳组成。

Limit switch working limit switch and limit switch, limit switch is used to give the work mechani* of action in place signal. Limit switch is to prevent the agency beyond the scope of design and accident. Work limit switches are installed in the *ition of the mechani* to change the conditi*witch, signal is given, for other related acti*. Limit switch installed in the mos*stal moveme*f mechani*, to protect the mechani* of action is too large there is damaged.
The main part of the switch is com*ed of the following materials
Mark of part*aterials
Contact Au corrosion resistance is superior, for *all load. Because of its soft texture (Vivtorinox hardness HV25 ~ 65), it is easy to adhesion (contact adhesive), and in the contact force under the condition of large contact easy to sag.
Alloy of gold, silver, 10% silver gold alloy AuAg 90% corrosion resistance is very good, hardness is HV30 ~ 90, higher than the gold, so it is widely used in *all load switch.
Platinum, gold, silver, 69% gold, 25% silver alloy PGS, 6% platinum alloy, corrosion resistance is very good, hardness is also the same with gold and silver alloy, widely used in *all load switch. Known as the "No. 1 alloy".
Silver palladium alloy AgPd, good corrosion resistance, but it is easy to adsorb organic gas generation polymer. 50% silver, 50% case of palladium, hardness is HV100 ~ 200.
Silver Ag electrical conductivity, thermal conductivity is one of the largest in the metal. Although the exhibit lower contact resistance, but the drawback*easy to generate sulfide film in sulfide gases in the environment, in the *all load area is easy to produce bad. Hardness is HV25 ~ 45. For more general load switch.
Silver, nickel alloy AgNi 90% silver, 10% silver, nickel and silver nickel alloy electric conductivity in close, arc resistance, excelle*esistance to melting. Hardness is HV65 ~ 115.
Silver, indium, tin alloy AgInSn hardness, high melting point, excellent arc resistance, not easy to melt or transfer.
The movable spring, the movable plate spring with phosphor bronze C5210 rolling resistance, fatigue resistance and corrosion resistance. H*e carried out annealing treatment. If the spring critical value (Kb0.075) of C5210-H i*ore than 40kgf/mm2, C5210-EH i*ore than 47kgf/mm2, the lower, are widely used in the *all micro switch.

人主之害,不在乎不言用贤,而在乎不诚必用贤。夫言用贤者,口也;却贤者, 行也,口行相反,而欲贤者之至,不肖者之退也,不亦难乎!夫耀蝉者,务在明其 火,振其树而已;火不明,虽振其树,无益也。今人主有能明其德者,则天下归之, 若蝉之归明火也。
临事接民,而以义变应,宽裕而多容,恭敬以先之,政之始也。然后中和察断 以辅之,政之隆也。然后进退诛赏之,政之终也。故一年与之始,三年与之终。用 其终为始,则政令不行,而上下怨疾,乱所以自作也。书曰:“义刑义杀;勿庸以 即,女惟曰:未有顺事。”言先教也。
程者、物之准也,礼者、节之准也;程以立数,礼以定伦;德以叙位,能以授 官。凡节奏欲陵,而生民欲宽;节奏陵而文,生民宽而安;上文下安,功名之****也, 不可以加矣。
君者、国之隆也,父者、家之隆也。隆一而治,二而乱。自古及今,未有二隆 争重,而能长久者。
师术有四--而博习不与焉:尊严而惮,可以为师;耆艾而信,可以为师;诵 说而不陵不犯,可以为师;知微而论,可以为师:故师术有四--而博习不与焉。 水深而回,树落则粪本,弟子通利则思师。诗曰:“无言不雠,无德不报。”此之 谓也。
赏不欲僭,刑不欲滥。赏僭则利及小人,刑滥则害及君子。若不幸而过,宁僭 勿滥。与其害善,不若利*。
