球隔离泵是近十年来从国外引进并在国内迅速发展起来的一种矿山用矿浆输送设备,输送能力大,自动化程度高,环保程度高,维修方便,在国内新建的大中型矿山得到普遍应用。该设备的故障率较低,在使用的前几年(3～5年)需维修的故障大都是易损部位,如进排浆罐体、逆止阀、进回水清水阀和主动力清水泵等。这些部位的故障特征明显,位置易确定,一般能够在不影响生产的情况下迅速处理好[1]。该泵使用几年后,其液压系统会出现一些故障,检修难度相对较大。
Ball pump is the introduction of the past 10 years and the rapid development in the country with a mining slurry conveying equipment, transmission capacity, high degree of automation, environmental protection, easy maintenance, the newly established large and medium-sized mines are widely used . The equipment failure rate is low, in the first few years of use (3 to 5 years) to repair the most vulnerable parts, such as into the tank body, check valve, inlet and outlet water valve and the main dynamic clearance Pumps and so on. These parts of the obvious fault characteristics, easy to determine the location, usually without affecting the production of the case promptly deal with [1]. After several years of use of the pump, its hydraulic system will be some failure, maintenance is relatively difficult.
