Description
技术领域
本实用新型涉及油气田压裂技术领域,具体涉及一种变频一体机的电驱压裂半挂车。
背景技术
在全球的油气田压裂作业现场,柱塞泵的动力驱动方式主要有二种:
第一种是柴油发动机连接变速箱经传动轴驱动压裂柱塞泵工作。也就是说,动力源是柴油发动机,传动装置是变速箱和传动轴,执行元件是柱塞泵。
该配置模式存在以下缺点:
(1)、体积大重量大:柴油机驱动变速箱经传动轴驱动柱塞泵,体积大,重量大,运输受限,功率密度小。
(2)、不环保:柴油发动机驱动的压裂设备在井场运行过程中,会产生发动机废气污染和噪音污染,噪音超过105dBA,严重影响周围居民的正常生活。
(3)、不经济:柴油发动机驱动的压裂设备,设备初期的采购成本比较高,设备运行时单位功率燃料消耗费用高,发动机和变速箱的日常维护保养费用也很高。
第二种是电动机连接传动轴或者联轴器驱动柱塞泵工作。也就是说,动力源是电动机,传动装置是传动轴或者联轴器,执行元件是柱塞泵,也就是电驱压裂。
电驱压裂在某些电力设施配套较完善的地方应用还是相对比较广泛的,现有的电驱压裂设备,通常是采用配备专门的供电设备来提供驱动电源,供电设备与电驱压裂设备之间通常是一对一,或者由一个大功率供电设备拖几台电驱压裂设备(以下简称一对多),但无论是一对一还是一对多,在井场的实际使用时,都需要消耗过多的时间去排布电驱压裂设备与供电设备(即电驱压裂设备与供电设备需要成套配合使用);还需要将每台电驱压裂设备与供电设备连接,以使电驱压裂设备进入工作状态;以上过程都比较耗时耗力,且设备之间的连接线缆也较多,相对繁琐。
为此亟待一种经济、环保、体积更小、连接简单、结构简单的电驱压裂设备。
