在典型使用壽命范圍方面，工業(yè)控制機(jī)箱的平均壽命通常為 8 - 12 年，電子元件老化、散熱條件是影響其使用壽命的關(guān)鍵因素，隨著時(shí)間推移，電子元件性能逐漸衰退，而不良的散熱條件會(huì)加速元件老化；配電柜系統(tǒng)平均壽命在 10 - 15 年，接觸器壽命和絕緣性能對(duì)其使用壽命起著決定性作用，接觸器頻繁動(dòng)作會(huì)導(dǎo)致觸點(diǎn)磨損，絕緣性能下降則可能引發(fā)隱患；電機(jī)驅(qū)動(dòng)系統(tǒng)平均壽命為 5 - 10 年，軸承磨損、繞組絕緣狀況直接關(guān)系到其運(yùn)行時(shí)長(zhǎng)，軸承長(zhǎng)期運(yùn)轉(zhuǎn)產(chǎn)生磨損，繞組絕緣在電、熱、機(jī)械應(yīng)力作用下逐漸劣化；自動(dòng)化控制單元平均壽命處于 6 - 10 年區(qū)間，元器件迭代速度以及軟件兼容性是重要影響因素，隨著技術(shù)發(fā)展，舊有元器件可能難以滿(mǎn)足新需求，軟件更新也可能導(dǎo)致兼容性問(wèn)題 。

In terms of typical service life range, the average service life of industrial control chassis is usually 8-12 years. The aging of electronic components and heat dissipation conditions are key factors affecting their service life. Over time, the performance of electronic components gradually deteriorates, and poor heat dissipation conditions will accelerate component aging; The average lifespan of the distribution cabinet system is 10-15 years, and the lifespan and insulation performance of the contactor play a decisive role in its service life. Frequent operation of the contactor can cause contact wear, and a decrease in insulation performance may lead to safety hazards; The average lifespan of the motor drive system is 5-10 years, and bearing wear and winding insulation directly affect its operating time. Long term operation of the bearings results in wear, and winding insulation gradually deteriorates under electrical, thermal, and mechanical stress; The average lifespan of automation control units is in the range of 6-10 years, and the iteration speed of components and software compatibility are important influencing factors. With the development of technology, old components may be difficult to meet new needs, and software updates may also lead to compatibility issues.

影響壽命的關(guān)鍵因素及應(yīng)對(duì)措施主要涉及電氣元件老化、機(jī)械部件磨損以及環(huán)境適應(yīng)性等方面。電氣元件老化表現(xiàn)為電容鼓包、繼電器觸點(diǎn)氧化等問(wèn)題，電容鼓包意味著內(nèi)部電解質(zhì)可能出現(xiàn)泄漏或氣化，影響電路性能，繼電器觸點(diǎn)氧化會(huì)導(dǎo)致接觸電阻增大，降低控制精度。針對(duì)這些問(wèn)題，有效的解決方案是每 2 年進(jìn)行電容 ESR 檢測(cè)，當(dāng)容值偏差超過(guò) 20% 時(shí)及時(shí)更換電容，使用鍍金觸點(diǎn)繼電器，其壽命可超過(guò) 100 萬(wàn)次，有效減少觸點(diǎn)氧化帶來(lái)的故障。

The key factors and countermeasures that affect lifespan mainly involve electrical component aging, mechanical component wear, and environmental adaptability. The aging of electrical components manifests as problems such as capacitor bulging and oxidation of relay contacts. Capacitor bulging means that the internal electrolyte may leak or vaporize, affecting circuit performance. Oxidation of relay contacts can increase contact resistance and reduce control accuracy. An effective solution to these issues is to conduct ESR testing of capacitors every 2 years. When the capacitance deviation exceeds 20%, capacitors should be replaced in a timely manner. Gold plated contact relays can be used, with a lifespan of over 1 million times, effectively reducing faults caused by contact oxidation.

機(jī)械部件磨損常以導(dǎo)軌卡滯、軸承異響等典型故障呈現(xiàn)，導(dǎo)軌卡滯會(huì)影響設(shè)備運(yùn)動(dòng)精度和順暢性，軸承異響則預(yù)示著軸承可能出現(xiàn)損壞。相應(yīng)的維護(hù)方案需結(jié)合設(shè)備運(yùn)行狀況和使用環(huán)境，對(duì)機(jī)械部件進(jìn)行定期檢查和保養(yǎng)，如對(duì)導(dǎo)軌進(jìn)行潤(rùn)滑、清理雜質(zhì)，對(duì)軸承進(jìn)行潤(rùn)滑脂補(bǔ)充或更換 。環(huán)境適應(yīng)性也是影響設(shè)備壽命的關(guān)鍵因素，關(guān)鍵指標(biāo)涵蓋溫度、濕度和粉塵防護(hù)等級(jí)。設(shè)備適宜運(yùn)行溫度通常在 - 20℃~+50℃，超出該范圍則需要配備溫控系統(tǒng)進(jìn)行調(diào)節(jié)；適宜濕度范圍為 30%~70% RH，在潮濕環(huán)境中需安裝防凝露加熱器，避免設(shè)備內(nèi)部產(chǎn)生冷凝水而損壞元件；粉塵環(huán)境下，設(shè)備需具備 IP54 以上防護(hù)等級(jí)，防止粉塵進(jìn)入設(shè)備內(nèi)部影響正常運(yùn)行 。

Mechanical component wear often presents typical faults such as rail jamming and bearing abnormal noise. Rail jamming can affect the accuracy and smoothness of equipment movement, while bearing abnormal noise indicates that the bearing may be damaged. The corresponding maintenance plan should be based on the operating conditions and usage environment of the equipment, and regular inspections and maintenance of mechanical components should be carried out, such as lubricating the guide rails, cleaning impurities, and supplementing or replacing lubricating grease for bearings. Environmental adaptability is also a key factor affecting equipment lifespan, with key indicators including temperature, humidity, and dust protection level. The suitable operating temperature for the equipment is usually between -20 ℃ and+50 ℃. If it exceeds this range, a temperature control system needs to be equipped for adjustment; The suitable humidity range is 30%~70% RH, and anti condensation heaters should be installed in humid environments to avoid condensation water inside the equipment and damage to components; In dusty environments, equipment must have a protection level of IP54 or above to prevent dust from entering the interior and affecting normal operation.

為延長(zhǎng)設(shè)備壽命，還需制定科學(xué)合理的維護(hù)策略。預(yù)防性維護(hù)計(jì)劃尤為重要，每日需進(jìn)行異常噪音和溫升檢查，及時(shí)發(fā)現(xiàn)設(shè)備運(yùn)行初期的異常狀況；每月進(jìn)行緊固件扭矩校驗(yàn)，嚴(yán)格按照標(biāo)準(zhǔn)扭矩表操作，防止因緊固件松動(dòng)引發(fā)設(shè)備故障，同時(shí)對(duì)散熱風(fēng)扇進(jìn)行除塵處理，采用壓縮空氣吹掃的方式風(fēng)扇表面和內(nèi)部的灰塵，保障散熱效果；每年開(kāi)展絕緣電阻測(cè)試，要求絕緣電阻大于 1MΩ，進(jìn)行接地電阻檢測(cè)，確保接地電阻小于 4Ω，保障設(shè)備電氣。

To extend the lifespan of the equipment, it is necessary to develop a scientifically reasonable maintenance strategy. The preventive maintenance plan is particularly important, and daily checks for abnormal noise and temperature rise are required to promptly detect any abnormal conditions during the initial operation of the equipment; Perform monthly torque verification of fasteners and strictly follow the standard torque table to prevent equipment failure caused by loose fasteners. At the same time, dust removal treatment is carried out on the cooling fan, using compressed air blowing to remove dust on the surface and inside of the fan to ensure heat dissipation effect; Carry out insulation resistance testing every year, requiring insulation resistance greater than 1M Ω, and conduct grounding resistance testing to ensure that the grounding resistance is less than 4 Ω, ensuring the electrical safety of the equipment.

此外，關(guān)鍵部件更換周期表為設(shè)備維護(hù)提供了明確指引，冷卻風(fēng)扇在使用 3 年且轉(zhuǎn)速下降超過(guò) 15% 時(shí)需進(jìn)行更換；電源模塊使用 5 年，若輸出電壓波動(dòng)超過(guò) 5% 則應(yīng)更換；通信線(xiàn)纜使用 8 年后，通過(guò)阻抗測(cè)試判斷是否需要更換；機(jī)械傳動(dòng)部件在使用 5 - 7 年時(shí)，依據(jù)振動(dòng)分析（參照 ISO 標(biāo)準(zhǔn)）結(jié)果決定是否更換，從而保障設(shè)備始終處于良好運(yùn)行狀態(tài) 。

In addition, the replacement cycle table for key components provides clear guidance for equipment maintenance, and the cooling fan needs to be replaced after 3 years of use and when the speed drops by more than 15%; The power module should be replaced if the output voltage fluctuates by more than 5% after 5 years of use; After using communication cables for 8 years, determine whether they need to be replaced through impedance testing; Mechanical transmission components should be replaced based on vibration analysis (referring to ISO standards) results after 5-7 years of use, in order to ensure that the equipment is always in good operating condition.
