机械维修工作中最苦恼的事莫过于缺少配件,特别是修理进口工程机械时,往往因零、部件不能及时满足换用需要而使主机无法迅速恢复工作能力,给修理和使用单位造成很大的压力。我单位使用的日本东洋运搬机株式会社生产的TCM-75B装载机,有两台车液压系统的重要元件——P20300A型主工作油泵失效,我们改用了山东青州(原益都)液压元件厂生产的GBG3125型油泵。经使用半年后检查,油泵各件均正常。现在把我们在改装过程中处理有关技术问题作一简要介绍,以供参考。
The most troublesome thing in mechanical maintenance work is the lack of spare parts. Especially when repairing imported construction machinery, the zero or parts cannot meet the needs of replacement in time, so that the host can’t quickly restore the working ability, causing great damage to repair and use units. pressure. The TCM-75B loader manufactured by Japan Toyo Transporter Co., Ltd. used in our company has an important component of the hydraulic system of the two vehicles. The main working oil pump of model P20300A has failed. We have used the hydraulic components of Shandong Qingzhou (Yidu). The GBG3125 oil pump produced by the factory. After half a year inspection, all parts of the oil pump are normal. We will now give a brief introduction of the relevant technical issues in the conversion process for reference.
