什么是电梯维修？贵州电梯告诉你！

什么是维修，什么是改造，很多电梯维保单位和使用单位都存在疑惑。

参考国质检特〔2014〕260号，电梯施工类别划分表（修订版），什么是电梯的维修，什么是改造？这里就是标准。

施工类别 施工内容

安 装 采用组装、固定、调试等一系列作业方法，将电梯部件组合为具有使用价值的电梯整机的活动；包括移装。

改 造

贵州电梯认为采用更换、调整、加装等作业方法，改变原电梯主要受力结构、机构（传动系统）或控制系统，致使电梯性能参数与技术指标发生改变的活动；包括：

1. 改变电梯的额定（名义）速度、额定载重量、提升高度、轿厢自重（制造单位明确的预留装饰重量除外）、防爆等级、驱动方式、悬挂方式、调速方式以及控制方式；

ps1： 改变电梯的调速方式是指：如将乘客或载货电梯的交流变极调速系统改变为交流变频变压调速系统；或者改变自动扶梯与自动人行道的调速系统，使其由连续运行型改变为间歇运行型等；

ps2：规格是指：制造单位对产品不同技术参数、性能的标注，如：工作原理、机械性能、结构、部件尺寸、安装位置等；型号是指：制造单位对产品按照类别、品种并遵循一定规则编制的产品代码。

2. 加装或更换不同规格、不同型号的驱动主机、控制柜、限速器、安全钳、缓冲器、门锁装置、轿厢上行超速保护装置、轿厢意外移动保护装置、含有电子元件的安全电路及可编程电子安全相关系统、夹紧装置、棘爪装置、限速切断阀（或节流阀）、液压缸、梯级、踏板、扶手带、附加制动器；

3. 改变层（轿）门的类型、增加层门或轿门；

4. 加装自动救援操作（停电自动平层）装置、能量回馈节能装置、读卡器（IC卡）等，改变电梯原控制线路。

修 理

用新的零部件替换原有的零部件，或者对原有零部件进行拆卸、加工、修配，但不改变电梯的原性能参数与技术指标的活动。修理分为重大修理和一般修理两类。

1. 重大修理包括：

（1）更换同规格的驱动主机及其主要部件（如电动机、制动器、减速器、曳引轮）；

（2）更换同规格的控制柜；

（3）更换不同规格的悬挂及端接装置、高压软管、防爆电气部件；

（4）更换防爆电梯电缆引入口的密封圈。

2. 一般修理包括修理和更换下列部件（保持原规格）实施的作业：门锁装置、控制柜的控制主板和调速装置、限速器、安全钳、缓冲器、悬挂及端接装置、轿厢上行超速保护装置、轿厢意外移动保护装置、含有电子元件的安全电路及可编程电子安全相关系统、夹紧装置、棘爪装置、限速切断阀（或节流阀）、液压缸、高压软管、防爆电气部件、梯级、踏板、扶手带、附加制动器等。

维护保养

为保证电梯符合相应安全技术规范以及标准的要求，对电梯进行的清洁、润滑、检查、调整以及更换易损件的活动；包括裁剪、调整悬挂钢丝绳，不包括上述安装、改造、修理规定的内容。

更换同规格、同型号的门锁装置、控制柜的控制主板和调速装置、缓冲器、梯级、踏板、扶手带、围裙板等实施的作业视为维护保养。

What is the maintenance, what is the transformation, many elevator maintenance units and use units have doubts.

Reference country quality inspection special [2014] 260, elevator construction category division table (Revised Edition), what is the maintenance of the elevator, what is the transformation? Here is the standard.

Construction content of construction category

The installation adopts a series of working methods such as assembly, fixing, debugging and so on, and combining the elevator components into the activities of the whole elevator with the use value, including the transfer.

Reform

By changing operation methods such as replacement, adjustment and installation, we can change the main force structure, the transmission system or the control system of the original elevator, resulting in changes in the performance parameters and technical indicators of the elevator.

1., change the nominal speed, rated load weight, lifting height, car weight (except for the reserved decorative weight of manufacturing unit), explosion-proof level, driving mode, suspension mode, speed control mode and control mode.

PS1: change speed lift refers to: such as the passenger or cargo elevator AC timing system is changed to AC VVVF system; or change the escalator and automatic sidewalk system, the continuous operation of type change for intermittent operation etc.;

PS2: specification refers to: manufacturing units of products with different technical parameters, performance of the label, such as: working principle, mechanical properties, structure, component size, installation position; model refers to: manufacturing units of products in accordance with the categories of varieties and follow certain rules for product code.

2. installation or replacement of different specifications, different types of safety driving circuit, host control cabinet, speed limiter, safety gear, buffer, door lock device, ascending car overspeed protection device and a car accident mobile protection device, containing electronic components and programmable electronic safety related systems, a clamping device, a pawl device, speed limit shut-off valve (or throttle valve), hydraulic cylinder, cascade, pedal, handrail, additional brake;

3. the type of the change layer (sedan chair), the increase of the layer gate or the sedan door;

4. install automatic rescue operation (power stop automatic leveling) device, energy feedback energy saving device, card reader (IC card) and so on, change the original control line of elevator.

Repair

Replace original parts with new components, or dismantle, process and repair old parts, but do not change the activities of elevator's original performance parameters and technical indicators. Repair is divided into two categories: major repairs and general repairs.

1. major repairs include:

(1) replace the same specifications of the main engine and its main components (such as motor, brake, reducer, traction wheel);

(2) replace the same specifications of the control cabinet;

(3) replace the different specifications of the suspension and end connection devices, high pressure hose, explosion-proof electrical components;

(4) replace the sealing ring of the inlet of the explosion-proof elevator cable.

2. general repairs include repair and replacement of the following components (original specifications) the implementation of operations: lock device control cabinet, control board and control device, speed limiter, safety gear, buffer, suspension and end safety circuit device, ascending car overspeed protection device and a car accident mobile protection device, containing electronic components and programmable electronic safety related systems, a clamping device, a pawl device, speed limit shut-off valve (or throttle valve), hydraulic cylinder, high-pressure hose, explosion-proof electrical components, cascade, pedal, handrail, additional brake etc..

Maintenance

In order to ensure that the elevator is in line with the requirements of the corresponding safety technical specifications and standards, we should clean, lubricate, check and adjust the elevator and change the activities of vulnerable parts, including cutting and adjusting the suspended wire rope, excluding the contents mentioned above.

Replacement of the same size and the same type of door lock device, control cabinet, control board and speed control device, buffer, step, pedal, handrail belt, apron plate and other operations shall be considered as maintenance.
