安装截止阀 泥浆泵使用寿命延长

   巧用截止阀,延伸泥浆泵使用寿命

  煤矿发掘工程中,用到比较多的是泥浆泵,由于这些场所所发生的废水中,具有很多固体颗粒等杂质。其他一些泵底子就不合适这些打具有杂质的液体。因而用到更多的是泥浆泵。

  连采队掘进出产时粉尘较大,所以连采机的除尘显得尤为要害。依照规则,掘进出产时必须将连采机表里喷雾翻开,而内喷雾所发生的沉淀物较多,很简单形成泥浆泵阻塞,平常每次清洁都要将泥浆泵翻开,费时吃力,如整理不及时就会损坏泥浆泵。

  煤机维修工工人对于这一状况,具体翻阅有关书本并依据作业经验,在连采机内喷雾排污管上安装了一个截止阀。当泥浆泵阻塞时,手动封闭截止阀,喷雾水延排污管直接进入泥浆泵,对泥浆泵进行反冲刷,冲刷结束后,翻开截止阀,污水从排污管排出,简化了泥浆泵的清洁保护作业,能够延伸泥浆泵的使用寿命。

    泥浆泵的排量就是以每分钟排出若干升核算,它与钻孔直径及所需求的冲洗液自孔底上返速度有关,即孔径越大,所需排量越大。冲洗液的上返速度可以把钻头切削下来的岩屑、岩粉及时冲离孔底,并可靠地携带到地表。地质岩心钻探时,通常上返速度在0.4~1米/分左右。

 

Using the cut-off valve, extending the service life of slurry pump

Coal mine excavation engineering, use of mud pump, due to the occurrence of theseplaces in the waste water, has a lot of solid particles and other impurities. Somepumps have no suitable these play with impurities in liquid. So the use is more of amud pump.

Even the recovery team driving production large dust, dust and so even the mining machine is the key. In accordance with the rules, excavation must be continuous mining machine inside and outside spray open production, what happened in spraydeposit more, very simple form of mud pump blocked, usually every cleaning will bemud pump open, time-consuming and difficult, such as not timely collation will damage the mud pump.

Coal machine repair workers for this specific situation, go through the relevant booksand according to the operation experience, in the continuous mining machine spraydischarge tube mounted on a globe valve. When the mud blocking, manual closedstop valve, spray water to delay directly into the mud pump discharge pipe, flushingbrush on the mud pump, washed after the end, open the valve, the sewagedischarged from a drain, simplifies the cleaning work of mud pump, can extend the service life of slurry pump.

Mud pump output is from a number of liters per minute accounting, it with the diameter and the drilling fluid requirements from the hole on the back end of the speed, the larger the aperture, the greater the required capacity. The fluid back to the bit rate can be cut, rock cuttings from the hole bottom red powder in a timely manner, and to reliably bring to the surface. Geological core drilling, usually on the return rate of 0.4 ~ 1 m / min or so.
