化工行业电动叉车安全选型与防爆要求(图1)


化工行业生产仓储场景常涉及易燃易爆挥发性溶剂、可燃粉体等特殊物料,物料搬运环节的设备安全直接关系整体厂区的生产运行稳定性,电动叉车作为厂区内部高频使用的搬运设备,其选型合理性与防爆性能是否达标,是化工企业安全生产管理的核心模块之一。

开展电动叉车安全选型工作时,首先要对照作业区域的危险等级划分标准匹配对应防护级别的设备,不能直接选用普通民用场景的电动叉车投入高危化工库区使用。选型前要逐一梳理作业场景的实际属性,比如涉及散装可燃粉体的库区,要优先考虑整机防粉尘堆积的结构设计;涉及低闪点液体周转的区域,要确认设备的全链条静电导出机制符合场景要求。同时要结合日常搬运的常见物料重量、作业通道宽度、仓储货架高度,匹配对应额定荷载、车身尺寸、举升高度的设备,避免长期超载使用、或是设备参数和场景适配度不足带来的额外安全隐患。针对不同形态的化工物料包装,比如桶装、集装罐、特种包装袋等,要选配原厂适配的合规属具,不要自行改装未经过安全校验的非标准属具。

关于电动叉车的防爆合规要求,首先要符合国内现行的工业防爆相关安全标准,所有运行过程中可能产生电火花、高温的部件,包括驱动电机、控制电路板、接线端子、电池管理模块等,都要做对应的隔爆、封胶或是绝缘防护处理,避免运行过程中内部产生的火花泄露到外部高危环境中。设备外壳的金属部件要做防静电喷涂处理,所有外露的金属结构都要设置可靠的静电导出路径,避免运行摩擦或是物料接触过程中产生静电积聚放电。电动叉车的动力电池组要配置完善的过充、过温、过流预警保护机制,设备日常运维过程中要及时清理散热缝隙处堆积的可燃粉尘,不要私自拆解更换原厂的防爆结构部件,所有的维修改装操作都要在非危险区域开展。

化工企业也要将电动叉车的安全管理纳入日常巡检体系,定期组织作业人员开展防爆操作规范培训,禁止作业人员私自给叉车加装无关用电设备,从采购准入、日常使用、定期维保全环节落实管理要求,全方位降低搬运环节的安全隐患。
