逻辑阀亦称二通插装阀,由于它具有结构紧凑,制造方便,功率损失小,通油能力大,密封性好,三化程度高,易于集成等一系列优点,而得到国内外普遍重视,发展很快。在国内,锻压机械、冶金机械、轻工机械等液压控制系统已有不少的应用实例,但是否能应用于建筑桩工机械里呢?我们通过反复分析、研究,自行设计了静力压桩机系列产品的通用型液压系统。压桩机液压系统由两部分组成,即压桩 Logic valve, also known as two-way cartridge valve, is widely appreciated at home and abroad due to its compact structure, convenient manufacture, low power loss, large oil-passing capacity, good sealing performance, high degree of three-phase, and easy integration. ,fast development. In China, there are many examples of hydraulic control systems such as forging machinery, metallurgical machinery, and light industrial machinery. However, can it be used in building piling machinery? We have designed static piles by ourselves through repeated analysis and research. General-purpose hydraulic system for machine series products. The hydraulic system of the pile driver consists of two parts, namely the pile
