液压元件的很多内油道和沟槽是铸造成型的。清除铸件内腔余型砂,是清理毛坯的主要工作量。由于残留的型砂紧贴在铸件内腔曲曲弯弯的内壁上,又不易清理彻底。当元件工作时,这些型砂被油浸润和冲击后,不定时的进入系统中,这对元件寿命和性能的破坏性很大,在用户中造成很坏的影响。我厂产品中,老式叶片泵泵体有铸造内油道。因批量不大,没有采用“水爆清砂”,“电化学清砂”,“电液压清砂”。以前只是用铅丝做成的工具,手工进行控、挖、挫、锉、
Many of the hydraulic channels and grooves in the hydraulic components are cast. Clear the casting cavity cavity sand, is the main workload to clean the rough. As the residual sand clinging to the curved inner wall of the casting cavity is not easy to clean thoroughly. When the components work, the sand is infiltrated and impacted by the oil and enters the system from time to time, which is devastating to the components’ life and performance, causing a very bad effect on the users. I plant products, the old vane pump impeller within the cast oil. Due to the small batch, did not use “water burst sand”, “electrochemical sand”, “electro-hydraulic sand cleaning.” Used to be made of wire tools, manual control, digging, frustration, file,
