3500/25 149369-01 機(jī)械保護(hù)系統(tǒng)中還包括限速器和安全鉗等安全設(shè)備

3500/25 149369-01 機(jī)械保護(hù)系統(tǒng)主要涉及抱閘裝置、限速器、安全鉗等安全設(shè)備，其工作原理主要是通過(guò)機(jī)械裝置進(jìn)行控制，即使在斷電的情況下也可以閉合開(kāi)關(guān)門，保護(hù)人員。

具體來(lái)說(shuō)，當(dāng)電梯運(yùn)行的速度超過(guò)其最大的允許速度時(shí)，限速器會(huì)激發(fā)抱閘裝置和安全鉗使電梯停住。當(dāng)出現(xiàn)緊急事故時(shí)，轎廂運(yùn)行太快，限速器通過(guò)離心力卡住安全繩，安全繩操作安全鉗，使電梯停住。

此外，3500/25 149369-01 機(jī)械液壓過(guò)速保護(hù)系統(tǒng)通常由離心探測(cè)器、切換閥、脫扣器和機(jī)械位置開(kāi)關(guān)等部分組成。其中離心探測(cè)器主要實(shí)時(shí)監(jiān)測(cè)發(fā)電機(jī)組的運(yùn)轉(zhuǎn)速度，當(dāng)發(fā)電機(jī)組轉(zhuǎn)速與額定轉(zhuǎn)速相符時(shí)，所產(chǎn)生的離心力相對(duì)較小，所以不會(huì)啟動(dòng)過(guò)速保護(hù)系統(tǒng)。但隨著發(fā)電機(jī)組轉(zhuǎn)速的提升，離心力也會(huì)不斷的增大，當(dāng)壓力彈簧所承受的壓力達(dá)到一定值時(shí)，彈簧會(huì)被大幅度壓縮，從而使與其相連的活動(dòng)柱塞發(fā)生位移撞擊切換閥，然后激發(fā)過(guò)速保護(hù)系統(tǒng)。與此同時(shí)，機(jī)械液壓過(guò)速保護(hù)系統(tǒng)的電氣接點(diǎn)導(dǎo)通，向上位機(jī)發(fā)送事故停機(jī)信號(hào)，確保工作人員能夠及時(shí)發(fā)現(xiàn)意外狀況，并作出合理的處理決定。

3500/25 149369-01 在電梯的機(jī)械保護(hù)系統(tǒng)中，抱閘裝置是控制開(kāi)關(guān)門的重要部分。抱閘裝置主要由制動(dòng)輪和制動(dòng)器組成，它們通常安裝在曳引輪的兩側(cè)。當(dāng)電梯正常運(yùn)行時(shí)，制動(dòng)器處于打開(kāi)狀態(tài)，允許電梯門的開(kāi)閉。如果電梯出現(xiàn)故障或斷電，抱閘裝置中的制動(dòng)器會(huì)立即合攏，將制動(dòng)輪抱緊，從而使電梯停止運(yùn)行。

在斷電的情況下，電梯的控制電路失去了電力供應(yīng)，但是抱閘裝置仍然可以通過(guò)機(jī)械方式控制開(kāi)關(guān)門。這是因?yàn)楸чl裝置的設(shè)計(jì)采用了機(jī)械儲(chǔ)能結(jié)構(gòu)，可以在斷電時(shí)釋放儲(chǔ)存的能量，驅(qū)動(dòng)制動(dòng)器合攏。這種設(shè)計(jì)可以保證即使在電力故障的情況下，電梯門也能夠快速關(guān)閉，從而保障乘客的安全。

除了抱閘裝置外，3500/25 149369-01 機(jī)械保護(hù)系統(tǒng)中還包括限速器和安全鉗等安全設(shè)備，它們?cè)陔娞葸\(yùn)行過(guò)程中起到監(jiān)測(cè)和限制速度的作用，可以在電梯超速或失控時(shí)及時(shí)采取制動(dòng)措施，防止事故發(fā)生。這些設(shè)備的正常運(yùn)作對(duì)于電梯的安全運(yùn)行至關(guān)重要，因此需要定期進(jìn)行維護(hù)和檢查。

綜上所述，3500/25 149369-01 機(jī)械保護(hù)系統(tǒng)通過(guò)抱閘裝置、限速器和安全鉗等設(shè)備的工作原理，實(shí)現(xiàn)了在斷電情況下控制開(kāi)關(guān)門的功能，從而保障了乘客的安全。

3500/25 149369-01 Mechanical protection system mainly involves safety equipment such as brake device, speed limiter, safety clamp, etc. Its working principle is mainly controlled by mechanical device, even in the case of power failure can also close the door, to protect personnel.

Specifically, when the speed of the elevator exceeds its maximum allowable speed, the governor will trigger the brake holding device and the safety clamp to stop the elevator. When there is an emergency, the car runs too fast, the speed limiter jams the safety rope through centrifugal force, and the safety rope operates the safety clamp to stop the elevator.

In addition, the 3500/25 149369-01 mechanical hydraulic overspeed protection system is usually composed of centrifugal detectors, switching valves, release devices and mechanical position switches. Among them, the centrifugal detector mainly monitors the running speed of the generator set in real time. When the speed of the generator set is consistent with the rated speed, the centrifugal force generated is relatively small, so the overspeed protection system will not be started. However, with the increase of the speed of the generator set, the centrifugal force will continue to increase, when the pressure of the pressure spring reaches a certain value, the spring will be greatly compressed, so that the connected movable plunger displacement impact switch valve, and then stimulate the overspeed protection system. At the same time, the electrical contact of the mechanical hydraulic overspeed protection system is switched on, and the accident stop signal is sent to the upward machine to ensure that the staff can detect the unexpected situation in time and make reasonable treatment decisions.

3500/25 149369-01 In the mechanical protection system of the elevator, the brake holding device is an important part of the control of opening and closing. The brake holding device is mainly composed of a brake wheel and a brake, which are usually installed on both sides of the traction wheel. When the elevator is operating normally, the brake is in the open state, allowing the elevator door to open and close. If the elevator fails or there is a power failure, the brakes in the brake device will immediately close, tightening the brake wheel, so that the elevator stops running.

In the case of power failure, the control circuit of the elevator loses power supply, but the brake holding device can still control the opening and closing of the door by mechanical means. This is because the design of the brake holding device uses a mechanical energy storage structure, which can release the stored energy in the event of power failure and drive the brake to close. This design ensures that even in the event of an electrical failure, the elevator doors can be closed quickly, thus guaranteeing the safety of passengers.

In addition to the brake holding device, the 3500/25 149369-01 mechanical protection system also includes safety equipment such as speed limiters and safety clamps, which play a role in monitoring and limiting speed during the operation of the elevator, and can take timely braking measures when the elevator is speeding or out of control to prevent accidents. The proper operation of these devices is essential for the safe operation of the elevator and therefore requires regular maintenance and inspections.

In summary, the 3500/25 149369-01 mechanical protection system realizes the function of controlling the opening and closing of the door in the case of power failure through the working principle of the brake holding device, the speed limiter and the safety clamp, thus ensuring the safety of passengers.
