近些年来,我国先后引进英国M K—Ⅱ型采煤机31台,占引进国外采煤机中比例较大。对进口设备检修时,备件不可能也不必要都采取进口的办法,可以自制。太原油泵油咀厂曾为山西省西山矿务局制造英国M K—Ⅱ型采煤机调高液压锁时,对其结构进行了改进。调高液压锁在英国M K—Ⅱ型采煤机液压元件中,是主要元件之一。它的性能,可靠性和工作寿命的长短,直接影响着采煤机的工作性能,关系着矿井工作面生产,矿井工作面安全和机械,人身事故的发生。参阅英国M K—Ⅱ采煤机调高液压锁的
In recent years, China has imported 31 M K-Ⅱ shearers from the United Kingdom, accounting for a large proportion of the imported shearer. Maintenance of imported equipment, spare parts can not and are not necessary to take the import approach, you can homemade. Taiyuan Oil Pump Tsui factory was made in Shanxi Province Xishan Mining Bureau British M K-Ⅱ type coal shearer raised the hydraulic lock, the structure was improved. Adjusting the hydraulic lock is one of the main components in British M K-Ⅱ shearer hydraulic components. Its performance, reliability and working life of a direct impact on the working performance of shearer, the production of mine face, mine face safety and mechanical, personal accidents.
