我公司购置的MPH100灰土拌和机是德国BOMAG公司的产品。在一次使用中发现从一个液压静平衡低速大扭矩驱动马达与转子连接处大量泄漏液压油。经拆检发现连杆铜保持环断裂破碎所致,由此产生一系列连锁反应,使连杆瓦磨损并有啃伤凹坑、各液压缸严重拉伤、活塞磨损、撞裂,使马达呈报废状态。进口配件价格昂贵,我们决定自己修复。从修后使用400多小时情况看,其性能可靠、效果理想,节省了大量开支。 The MPH100 ​​lime soil mixing machine purchased by our company is a product of Germany’s BOMAG company. In one use, it was found that a large amount of hydraulic oil leaked from the connection of a hydraulic static balance low speed high torque drive motor and the rotor. The dismantling inspection revealed that the copper retaining ring of the connecting rod was broken and fractured, resulting in a series of chain reaction, which caused the connecting rods to wear and have bruising pits, and the hydraulic cylinders were severely strained, the pistons were worn and cracked, and the motor was presented. Scrap state. Imported parts are expensive and we decided to repair ourselves. From the perspective of using more than 400 hours after the repair, the performance is reliable, the effect is ideal, and it saves a lot of expenses.
