液压接头是液压系统中，连接高压油管与高压油管之间的部件，液压管接头多种多样，为了确保润滑系统的清净，并供给机械设备轴承以洁净的润滑脂，需要将预安装后的管路拆下清洗，清洗方式主要是煤油清洗和酸洗。今天要为大家介绍的是在酸洗过程中的注意事项。

趣购彩The hydraulic joint is a part connecting the high-pressure oil pipe and the high-pressure oil pipe in the hydraulic system. There are many kinds of hydraulic pipe joints. In order to ensure the cleanness of the lubrication system and supply the mechanical equipment bearings with clean grease, it is necessary to remove the pre installed pipeline for cleaning. The main cleaning methods are kerosene cleaning and acid washing. Today, we would like to introduce the precautions in the pickling process.

趣购彩1. 酸洗前应清除干净焊接时的焊渣、溅出物和管子上的清漆等物。

趣购彩1. Before pickling, the welding slag, spatter and varnish on the pipe shall be cleaned.

趣购彩2.在拆卸、运输、酸洗时不要碰伤了螺纹、管路及密封面，可用胶带或塑料管堵封口。

2. Do not damage the thread, pipeline and sealing surface during disassembly, transportation and pickling, and seal with adhesive tape or plastic pipe plug.

趣购彩3.各螺纹部位应用塑料带、橡胶带等耐酸材料加以保护，或在脱脂、水洗后螺纹处涂上干油后再在酸液中除锈，以防酸液侵蚀。

趣购彩3. All thread parts shall be protected with acid resistant materials such as plastic tape and rubber belt, or the thread shall be coated with dry oil after degreasing and water washing, and then rust shall be removed in acid solution to prevent acid corrosion.

趣购彩4.在酸洗的时候注意看管子的标记，不要将管子的配合记号消失或模糊。

4. Pay attention to the mark of the pipe during pickling, and do not make the matching mark of the pipe disappear or blur.

5.酸洗前管子的焊接作业已全部完成。

趣购彩5. Before pickling, all welding operations of pipes have been completed.

除了在酸洗的过程中要注意，日常中也是需要去维护的。

In addition to pay attention to the pickling process, it also needs to be maintained in daily life.
