吸尘罩：对于固定焊位，常采用集气罩，它能覆盖焊接区域，密封性好，可有效捕集烟尘。对于灵活移动的焊位，一般使用吸气臂，其外层为耐高温软管，内衬钢丝，可灵活调整角度和位置，跟随焊接枪头移动，确保烟尘的有效捕集。吸气罩的罩口有马蹄形、礼帽型等多种形式，部分还带有风量调节阀门和防护网。

Vacuum hood: For fixed welding positions, a gas collection hood is often used, which can cover the welding area, has good sealing, and can effectively capture smoke and dust. For flexible welding positions, a suction arm is generally used, with a high-temperature resistant hose on the outer layer and steel wire lining. The angle and position can be flexibly adjusted to follow the movement of the welding gun head, ensuring effective capture of smoke and dust. The mouth of the suction hood comes in various forms such as horseshoe shaped and top hat shaped, and some also have air volume regulating valves and protective nets.

吸尘管路：用于连接吸尘罩和除尘设备，使烟尘能够顺利输送。管路材料可选用碳钢管、不锈钢管、耐负压塑料管等，一般采用专用 PVC 管材及弯头配件，具有表面光滑、污物附着力低的特点。为平衡管路末端风速风量，常采用渐变管径式设计。

Vacuum suction pipeline: used to connect the vacuum hood and dust removal equipment, enabling smooth transportation of smoke and dust. Pipeline materials can be selected from carbon steel pipes, stainless steel pipes, negative pressure resistant plastic pipes, etc. Special PVC pipes and elbow fittings are generally used, which have the characteristics of smooth surface and low adhesion to dirt. To balance the wind speed and volume at the end of the pipeline, a gradient pipe diameter design is often used.

除尘设备：常见的有布袋除尘器和滤筒除尘器等。滤筒除尘器具有净化效率高、外形尺寸小、过滤面积大、压力损失小、滤筒使用寿命长、安装维修快捷方便等特点。其结构包括进风管、排风管、箱体、灰斗、清灰装置、导流装置、气流分流分布板、滤筒及电控装置等。

Dust removal equipment: Common ones include bag filters and filter cartridges. The filter cartridge dust collector has the characteristics of high purification efficiency, small external dimensions, large filtration area, low pressure loss, long service life of the filter cartridge, and quick and convenient installation and maintenance. Its structure includes inlet duct, exhaust duct, box body, ash hopper, ash cleaning device, guide device, airflow distribution plate, filter cartridge, and electrical control device.

风机：为烟尘的输送提供动力，使烟尘能够克服管路阻力，顺利进入除尘设备。风机应根据管道系统的阻力和风量需求进行选型，且需配备变频器等调速装置，以便根据实际情况调整风量和风压，降低能耗和运行成本。

Fan: provides power for the transportation of smoke and dust, enabling smoke and dust to overcome pipeline resistance and smoothly enter the dust removal equipment. Fans should be selected based on the resistance and air volume requirements of the pipeline system, and equipped with speed control devices such as frequency converters to adjust the air volume and pressure according to the actual situation, reducing energy consumption and operating costs.

控制系统：可实时监测各焊位的烟尘浓度和除尘设备的运行状态，并根据需要调整风量和风压等参数。控制系统分为变频控制系统和非变频控制系统，变频控制系统需配备变频风机、电控管道风阀感应器件等，可根据开工工位数量进行主机的变频控制及管道通风管路的控制，达到定向输送吸风、节省运行能源的目的；非变频控制系统相对简单，设置主机开关，通过手动调节管道风阀来控制。

Control system: It can monitor the real-time concentration of smoke and dust at each welding position and the operation status of dust removal equipment, and adjust parameters such as air volume and pressure as needed. The control system is divided into frequency conversion control system and non frequency conversion control system. The frequency conversion control system needs to be equipped with frequency conversion fans, electric control pipeline air valve induction devices, etc. It can control the frequency conversion of the host and the ventilation pipeline of the pipeline according to the number of operating workstations, achieving the purpose of directional conveying and suction, and saving operating energy; The non variable frequency control system is relatively simple, with a host switch set and controlled by manually adjusting the pipeline air valve.

排灰装置：如旋转排灰阀，用于排出除尘器灰斗内积累的粉尘，确保除尘器的正常运行。

Ash discharge device: such as a rotary ash discharge valve, used to discharge the accumulated dust in the dust hopper of the dust collector, ensuring the normal operation of the dust collector.
