Description

一种半挂车载的涡轮压裂设备
技术领域
本发明涉及涡轮压裂技术领域，具体涉及一种半挂车载的涡轮压裂设备。
背景技术
在全球的油气田压裂作业现场，压裂设备的驱动方式主要有两种：
第一种驱动方式柴油发动机驱动，具体的方案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，执行元件是压裂柱塞泵。.
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压裂柱塞泵，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。
第二种驱动方式是电驱压裂，具体的方案是电动机连接传动轴或者联轴器驱动压裂柱塞泵工作。也就是说，动力源是电动机，传动装置是传动轴或者联轴器，执行元件是压裂柱塞泵。
电驱压裂本身虽然有很多优点，但是压裂井场的供电是电驱压裂实施的先决条件。通常情况下，压裂井场的供电问题并不好解决。要么井场的电网容量太小，带不动整个压裂机组；要么就是井场根本没有电网。所以常见的电驱压裂现场通常会使用发电机发电，最经济的发电燃料是采用天然气，但采用天然气需要用户租用或者购买燃气发电机组。对于一个没有电网的压裂井场来说，燃气发电机组的功率至少需要达到30MW，这对客户来说，购进如此大功率的燃气发电机组是笔不少的投资。更重要的是实际施工过程中因为燃气发电机组故障停机，则整个电驱压裂机组都会瘫痪，严重影响作业质量甚至还可能会导致作业事故。
为此亟待一种新的压裂设备，解决上述现有柴油发动机驱动压裂和电驱压裂的缺点，可以更好的满足全球油气田压裂市场的需求。

具体实施方式
实施例，如图1至8所示，一种半挂车载的涡轮压裂设备，所述涡轮压裂设备包括运输装置200，排气***，涡轮发动机500和柱塞泵600，所述涡轮发动机500为整个设备动力传动***的动力源，涡轮发动机500可以直接100％以天然气为燃料，相对于柴油驱动中的柴油消耗，以及电驱压裂设备中的燃气发电机组投资，大大降低了使用成本。当然涡轮发动机500也可以100％以燃油为燃料，优选为天然气，可以比燃油更降低燃料成本。所述排气***与涡轮发动机500的排气口连接，所述涡轮发动机500的输出端与柱塞泵600连接。所述排气***包括排气消音器300和排气管道400，所述排气消音器300通过排气管道400与涡轮发动机500的排气口连通。排气管道400用于将涡轮发动机500排气引导至排气消音器300内，排气消音器300可降低排气噪音。所述排气***、涡轮发动机500和柱塞泵600沿着动力传动的方向设在同一条直线上，即排气消音器30、排气管道400、涡轮发动机500和柱塞泵600沿着动力传动的方向设在同一条直线上，可避免过多的传动损耗，保证高效的传动性能，还能比现有设备的上下结构排布降低其设备重心，安全性、稳定性更好，运输更方便，结构更简单。所述运输装置200用于承载排气***，涡轮发动机500和柱塞泵600，所述柱塞泵600包括动力端总成1、液力端总成2和减速箱总成3，所述动力端总成1的一端与液力端总成2连接，所述动力端总成1的另一端与减速箱总成3连接，所述减速箱总成3包括行星减速箱和平行级减速箱10，所述行星减速箱和平行级减速箱10配合使用，其传动比为60：1—106:1。所述涡轮发动机500与减速箱总成3连接，减速箱总成3用于将涡轮发动机500的动力输出降速増扭后驱动柱塞泵600工作。在运输装置200上还可布置电瓶线、燃油箱、润滑油箱、液压油箱等部件，为涡轮发动机500，柱塞泵600等上装部件提供油品和支撑。
所述行星减速箱有2个，行星减速箱包括第一行星减速箱9和第二行星减速箱11，第一行星减速箱9的一端与动力端总成1的曲轴7连接，第一行星减速箱9的另一端与平行级减速箱10连接，平行级减速箱10的另一端与第二行星减速箱11连接，第二行星减速箱11的另一端与涡轮发动机500的传动轴连接。工作中，经涡轮发动机500传动轴传递出的动能，由第二行星减速箱11实现初次减速，由平行级减速箱10实现第二次减速，最后由第一行星减速箱9实现第三次减速。
通过改变减速箱总成3的传动比，从而提升最高输入转速(由现有的2100rpm增加到16000rpm，)，将现有涡轮发动机500与柱塞泵600之间通过2个减速箱和一个传动轴的连接方式，缩短到涡轮发动机500可以直接与柱塞泵600上的减速箱总成3连接，还能满足其降速要求，使得整体压裂设备结构简化了，长度缩短了，运输方便了，投资成本降低了，维修方便了。
所述行星减速箱包括一个太阳轮16、四个行星齿轮14和一个齿轮圈15，四个行星齿轮14组成行星齿轮机构，太阳轮16位于行星齿轮机构中心，行星齿轮14和相邻的太阳轮16、齿轮圈15处于常啮合状态，行星级减速箱采用四个均匀分布的行星齿轮14同时传递运动和动力，四个行星齿轮14因公转而产生的离心惯性力与齿廓间反作用力的径向分力相互平衡抵消，使主轴受力减小，实现大功率传递。所述平行级减速箱10包括小齿轮13和大齿轮12，小齿轮13与第一行星减速箱9中的太阳轮16同轴，大齿轮12与第二行星减速箱11的太阳轮16同轴。在平行级减速箱10内部经小齿轮13传递给大齿轮12可以实现减速。
所述减速箱总成3的输入角度可以根据输入要求进行调整。
所述动力端总成1的另一端与减速箱总成3通过花键或者柔性联轴器连接。
所述动力端总成1采用分段式结构设计，分段式设计使动力端总成1整体结构紧凑、加工制造更为容易，整泵的装配和后期维护也更为方便，同时也降低了加工成本。所述动力端总成1包括曲轴箱体4、十字头箱体5和间隔架6，所述十字头箱体5的一端与曲轴箱体4连接，所述十字头箱体5的另一端与间隔架6连接，液力端总成2设在间隔架6一端，通过螺栓依次穿过间隔架6、十字头箱体5与曲轴箱体4连接，减速箱总成3通过螺栓与曲轴箱体4连接，所述曲轴箱体4内的曲轴7采用合金钢锻造而成，包括六个轴颈7和五个曲拐8，相邻两个轴颈7之间设一个曲拐8，即五缸结构设计，采用五缸结构设计增加了柱塞泵600输出排量，同时与三缸泵相比，五缸泵作业平稳无振动，可以减少整泵的振动，延长使用寿命；所述曲拐8与曲轴7的旋转中心距离为120至160mm。通过进一步研究曲拐8与曲轴7的旋转中心距离，提升了柱塞泵600的最大功率，达到现在的5000-7000hp，保证柱塞泵600可以输出更高的压力，即为长冲程提供技术支持，其冲程可达到10-12in。可实现大排量的作业需求，同时降低泵的冲次，提高各零部件的使用寿命。
所述运输装置200包括底盘，所述底盘设有运输段，承载段和搭接段，所述运输段，承载段和搭接段依次连接，在涡轮压裂设备工作状态时，所述底盘的承载段能接触地面，在涡轮压裂设备运输状态时，所述底盘的承载段不接触地面。

在涡轮压裂设备工作状态时，所述底盘的承载段底面和车轮底部处于同一水平线上。承载段底面本身为一个水平面230加一个坡面240，工作状态时，承载段底面的水平面230全接触地面，增加了设备工作的稳定性。坡面240用于涡轮压裂设备运输状态时，被抬升的底盘脱离地面方便行走的。
所述搭接段的底部设有斜面210，在斜面210上设有凸起220，当在涡轮压裂设备运输状态时，所述斜面210能与外部拖力的设备配合使用，所述凸起220能帮助固定运输装置200，防止运输装置200与外部拖力的设备分离。外部拖力的设备可以是牵引车700，凸起可以是与牵引车700配合使用的牵引销。
