Description

一种通信机组油机过滤系统
本申请要求于2016年06月30日提交中国专利局、申请号为201610503925.7，发明名称为“一种通信机组油机过滤系统”的中国专利请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及过滤技术领域，特别涉及一种通信机组油机过滤系统。
背景技术
基站通信机组地处偏远地区，交通不便，维护成本高，为解决客户痛点，通信机组的维护间隔应尽量延长。大容量柴油箱，加大空滤、机滤、柴滤及机油自动补给是延长维护间隔的三大措施。
现有技术中油水分离器和柴油滤清器串接在低压油路中。油水分离器既能分离柴油中的水分，也起预滤作用，属第一级过滤。这种方案的特点是有两种过滤器件，二者的滤网密度通常不一样。备件也需要准备两种。原装小柴滤的维护间隔是500h，要增加到1000h，首保后需换装加大柴滤。实际使用表明，柴油较脏时，第一级滤芯容易堵塞。其他方案也有类似的的缺点，更重要的是两级滤芯的过滤密度应不同，第一级为粗滤，第二级为细滤。必须进行防呆设计，不得装反。也不得安装两只相同的滤芯。实际应用中这种情况确实发生过，其结果是第二级不起作用，第一级堵塞后，发动机性能即受到影响，机组维护间隔不能延长。某款机组采用了这种方案。机组运几百小时后，发现第一级滤芯堵塞严重。在相同条件下对两级滤芯进行了测试。500ml柴油通过第一级滤芯的时间是36min，通过第二级滤芯的时间只有20s。通过解剖两个滤清器，也发现堵塞程度对比明显。
