液压扭力扳手同步预紧

来源:http://fhgfx.com 日期:2021-03-15 发布人:admin

在风电设备安装,石油化工装置法兰安装,油、气、水等等行业管道安装,为保证法兰安装质量控制达到预紧密封效果,我们一般建议使用多同步定力矩扭力扳手预紧方案解决。其中,对于法兰预紧扭力较大,精度要求较高的工况,我们建议使用液压扭力扳手同步预紧。那么液压扭力扳手的同步预紧到底指什么

In the installation of wind power equipment, petrochemical plant flange installation, oil, gas, water and other industries pipeline installation, in order to ensure the flange installation quality control to achieve the best pre tightening sealing effect, we generally recommend using multi synchronous constant torque wrench pre tightening solution. Among them, for the flange pre tightening torque larger, higher accuracy requirements of the working conditions, we recommend the use of hydraulic torque wrench synchronous pre tightening. So what exactly does the synchronous pre tightening of hydraulic torque wrench mean
同步预紧实质就是采用均匀螺栓预紧力,在规则法兰面同步对角采用同等套设备同等扭力输出同时作业,从而达到受力面的平行均衡受力。理论来讲,全覆盖同步预紧效果肯定是更好的。但在液压扭力扳手,目前同台泵站更多可以做到拖四部扳手同时工作。因此,一般来说液压扭力扳手同步预紧选择肯定是一拖四。
The essence of synchronous pretightening is to use uniform bolt pretightening force, and use the same set of equipment with the same torque output at the same time in the synchronous diagonal of the regular flange surface, so as to achieve parallel and balanced stress of the stressed surface. Theoretically, the effect of full coverage synchronous preloading is definitely the best. But in the hydraulic torque wrench, at present, the same pumping station can pull up to four wrench at the same time. Therefore, generally speaking, the best choice of hydraulic torque wrench synchronous pre tightening is definitely one drag four.

但因为各现场设备数量和成本投入限制做不到四同步的也可以使用一台泵拖两部扳手的2同步作业,虽然效果和效率不及四同步,但肯定要好于单步扳手逐一锁紧的效果。
However, due to the limitation of the number of field equipment and cost input, if the four synchronization can not be achieved, the two synchronization operation of one pump dragging two spanners can be used. Although the effect and efficiency are not as good as the four synchronization, it is certainly better than the effect of one-step wrench locking one by one.
当然,液压扭力扳手同步预紧主要是针对法兰面的预计安装,如果工况螺栓分布不规则就没有必要考虑同步预紧,使用单步扳手预紧就可以。
Of course, the hydraulic torque wrench synchronous pre tightening is mainly for the flange surface is expected to install, if the distribution of bolts is irregular, there is no need to consider synchronous pre tightening, using a single step wrench pre tightening can.
