燃料 石油 水

聚结器过滤器是专门为分离液压油、柴油和船用柴油中的水而设计的。不需要昂贵的特殊油，这些可以被更便宜的压力液体所取代。根据VDMA标准表24568，服务友好处理根据VDMA标准表24568,HE组的压力流体必须保持含水量低于1000ppm(0.1%)。在HLP组，不应出现游离水。游离水总是导致浑浊。这是肉眼可见的。物理上，浊度是两相混合物(乳液)。加压液体中有很细的水滴。出于这个原因，很明显要对水滴进行机械分离:这种技术是基于聚结器原理的。细小的水滴被收集在几个不同的层中，并结合成更大的单元。 The resulting droplets leave the coalescer layer and hit a specially hydrophobic fabric. Here the separation from the pressurized liquid takes place. Sedimentation removes the water from the circuit. It is important for the process that a certain differential pressure is not exceeded. For proper operation, the viscosity must be taken into account. Theless emulsifying additives are present in the pressurized liquid, the better the coalescer works. The consequence is: expensive special oils in plants that are frequently threatened by water ingresscan be replaced by simple and inexpensive pressure fluids. With an easy-to-handle measuring device, contamination of hydraulic fluids can be quickly analyzed and measured.
