液壓扭力扳手同步預(yù)緊

在風(fēng)電設(shè)備安裝,石油化工裝置法蘭安裝,油、氣、水等等行業(yè)管道安裝,為保證法蘭安裝質(zhì)量控制達(dá)到預(yù)緊密封效果,我們一般建議使用多同步定力矩扭力扳手預(yù)緊方案。其中,對(duì)于法蘭預(yù)緊扭力較大,精度要求較高的工況,我們建議使用液壓扭力扳手同步預(yù)緊。那么液壓扭力扳手的同步預(yù)緊到底指什么

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
同步預(yù)緊實(shí)質(zhì)就是采用均勻螺栓預(yù)緊力,在規(guī)則法蘭面同步對(duì)角采用同等套設(shè)備同等扭力輸出同時(shí)作業(yè),從而達(dá)到受力面的平行均衡受力。理論來(lái)講,全覆蓋同步預(yù)緊效果肯定是更好的。但在液壓扭力扳手,目前同臺(tái)泵站更多可以做到拖四部扳手同時(shí)工作。因此,一般來(lái)說(shuō)液壓扭力扳手同步預(yù)緊選擇肯定是一拖四。
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?yàn)楦鳜F(xiàn)場(chǎng)設(shè)備數(shù)量和成本投入限制做不到四同步的也可以使用一臺(tái)泵拖兩部扳手的2同步作業(yè),雖然效果和效率不及四同步,但肯定要好于單步扳手逐一鎖緊的效果。
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.
當(dāng)然,液壓扭力扳手同步預(yù)緊主要是針對(duì)法蘭面的預(yù)計(jì)安裝,如果工況螺栓分布不規(guī)則就沒(méi)有必要考慮同步預(yù)緊,使用單步扳手預(yù)緊就可以。
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.
