盾构机液压系统通常使用板式换热器。板式换热器使用4000h后应进行拆检清洗,本文介绍板式换热器拆卸、清洗、装配、检测方法。1.结构板式换热器由多层槽形片叠加而成,两侧各有1块固定板,通过紧固螺栓固定。槽形片表面设有沟槽,构成冷却水道和液压油道2个腔体。板式换热器固定板上、下各有2个管件接口与2个腔体相通,冷却水和液压油可分别从固定板上面的2个管件接口进入,从下
Shield machine hydraulic systems usually use plate heat exchangers. Plate heat exchanger should be dismantled after 4000h cleaning, this article describes the plate heat exchanger removal, cleaning, assembly, testing methods. 1. Structure The plate heat exchanger is made up of multi-layer grooved pieces with one fixing plate on each side, which is fixed by fastening bolts. Groove groove surface with grooves, forming a cooling waterway and hydraulic gallery 2 cavities. Plate heat exchanger fixed plate, each under the two pipe fittings connected to the two chambers, cooling water and hydraulic oil from the fixed plate above the two pipe fittings into the mouth, from the next
