怎么才能避免电动叉车腐蚀问题?

来源:/ 日期:2021-08-10 发布人:hangong

1.考虑选择性能优异的耐腐蚀材料,例如镀锌板,彩色卷材,复合材料和工程塑料。

1. Consider selecting corrosion-resistant materials with excellent performance, such as galvanized sheet, color coil, composite materials and engineering plastics.
2.注意对裸露部件的保护,电气组件和连接器布置在内侧,或者添加了防护罩,电瓶叉车外露部分应设置防尘罩,以防止腐蚀和浸水,例如,在倾斜液压缸和转向液压缸的活塞杆的露出部设置有防尘罩,并且在电瓶叉车车身上的多个裸露的处理孔或功能孔上设有防水塞。
2. Pay attention to the protection of exposed parts. The electrical components and connectors are arranged on the inner side, or protective covers are added. The exposed parts of battery forklift shall be provided with dust covers to prevent corrosion and water immersion. For example, the exposed parts of piston rods of tilt hydraulic cylinder and steering hydraulic cylinder shall be provided with dust covers, A plurality of exposed processing holes or functional holes on the battery forklift body are provided with waterproof plugs.
3.考虑整体布置,以防止腐蚀性介质在电瓶叉车上积聚,尽量避开封闭区域,或保持密闭系统通风良好并排水,例如,考虑内燃叉车的通风和散热,发动机产生的废气通过净化和冷却尽可能多地从配重的下部排出或从配重的上部向上排出。 对于电瓶叉车,例如向前移动的叉车,可以打开通风窗以保持电动机的冷却和通风,电池盒的底部有一个漏液孔和一个蓄电池。
3. Consider the overall layout to prevent the accumulation of corrosive media on the battery forklift, avoid the closed area as far as possible, or keep the closed system well ventilated and drained. For example, consider the ventilation and heat dissipation of the internal combustion forklift, and the exhaust gas generated by the engine shall be discharged from the lower part of the counterweight or upward from the upper part of the counterweight as much as possible through purification and cooling. For battery forklifts, such as forklifts moving forward, the ventilation window can be opened to keep the motor cool and ventilated. There is a liquid leakage hole and a battery a the bottom of the battery box.
4.注意避免缝隙腐蚀,电化学腐蚀和应力腐蚀开裂,对于电瓶叉车,用密封剂密封不可避免的间隙结构,例如发动机罩的定制焊接间隙,对于异种金属的连接,请尝试选择电位接近的金属,或采取绝缘措施以避免电化学腐蚀。
4. Pay attention to avoid crevice corrosion, electrochemical corrosion and stress corrosion cracking. For battery forklift, seal the inevitable gap structure with sealant, such as the customized welding gap of engine hood. For the connection of dissimilar metals, try to select the metal with close potential, or take insulation measures to avoid electrochemical corrosion.
5.在设计零件时考虑到其均匀的腐蚀,请选择一种或几种组合的防腐蚀方法,叉车常用的保护方法包括涂层,电镀,转换膜以及防锈油脂,不同的过程具有不同的耐腐蚀性。
5. When designing parts, considering their uniform corrosion, please select one or several combined anti-corrosion methods. The common protection methods of forklift include coating, electroplating, conversion film and antirust grease. Different processes have different corrosion resistance.
6.零件的结构应便于实施保护过程,并在必要时打开处理孔,例如,对于电瓶叉车,燃油箱上的开口位置应使喷枪的喷嘴覆盖整个表面以进行喷丸处理,对于化学预处理的工件(例如高架护罩),应打开处理孔以防止液体积聚。
6. The structure of the parts shall facilitate the protection process and open the treatment hole when necessary. For example, for battery forklift, the opening position on the fuel tank shall make the nozzle of the spray gun cover the whole surface for shot blasting. For chemically pretreated workpieces (such as overhead shield), the treatment hole shall be opened to prevent liquid accumulation.
