泥浆失水量测定仪用于井场或实验室测量泥浆失水量,一定体积的泥浆在规定空气压力下流出的滤液量即为失水量。

The NS-1 mud water loss measuring instrument is used to measure the mud water loss in the well site or laboratory. The amount of filtrate flowing out of a certain volume of mud under the specified air pressure is the water loss.


泥浆失水量测定仪工作原理:

由打气筒提供的压缩空气,经减压阀后可调整为所需要压力值送往泥浆杯(进入泥浆杯的通道由放气阀控制)杯内的泥浆因压差失水。当压力表指针稳定的0.7Mpa时,计时30min,所流出的滤液即为该泥浆的失水量。当测量7.5min时失水量已大于8ml,此时的失水量乘以2,即为该泥浆的近似失水量,但需在记录中注明测定时间为7.5min。

NS-1 mud water loss meter works:

The compressed air supplied by the pump can be adjusted to the required pressure value through the pressure reducing valve and sent to the mud cup (the passage into the mud cup is controlled by the deflation valve). The mud in the cup loses water due to the pressure difference. When the gauge pointer is stable at 0.7Mpa, the time is 30min, and the filtrate that flows out is the water loss of the mud. When the water loss is more than 8ml when measuring 7.5min, the water loss at this time is multiplied by 2, which is the approximate water loss of the mud, but the measurement time is 7.5min.

泥浆失水量测定仪操作规程:

★先将支架放在平稳的台面上。 

★将减压手柄退出,使减压阀处于关死状态,此时无输出,然后关死放空阀。

★装好气瓶并拧紧盖,顺时针旋转减压阀手柄,使压力表指示0.5~0.6MPa。

★以左手拿住泥浆杯,用食指堵住泥浆杯气接头小孔,倒入被测泥浆,高度以低于密封圈2~3毫米A好,放好密封圈,铺平一张滤纸,拧紧泥浆杯盖,然后将泥浆杯连接在三通接头上,将20毫升量筒放在泥浆杯下面,对准出液孔。

★ 按逆时针方向缓缓旋转放空阀手柄,同时观察压力表指示。当压力表稍有下降或听见泥浆杯有进气声响时,即停止旋转放空阀手柄,微调减压阀手柄,使压力表指示为0.69MPa,泥浆杯内保持0.69MPa的恒定状态,当见到A滴滤液开始记时,30分钟时取下量筒,退出减压阀手柄,关死减压阀,顺时针旋转放空阀,泥浆杯内余气放出。取下泥浆杯,打开泥浆杯盖取出滤纸,洗净泥饼上的浮浆,测量泥饼厚度。

★冲洗擦干泥浆杯、杯盖、密封圈(凉干或烘干杯盖滤网)。

★记录下量筒内失水量。为缩短时间一般可测7.5分钟失水量成乘以2,必要时即需测30分钟失水量。

NS-1 mud water loss tester operating procedures:

★ Place the bracket on a stable table first.

★ The pressure reducing handle is withdrawn, so that the pressure reducing valve is in the dead state. At this time, there is no output, and then the vent valve is closed.

★ Install the gas cylinder and tighten the cover. Turn the pressure reducing valve handle clockwise to make the pressure gauge indicate 0.5~0.6MPa.

★ Hold the mud cup with your left hand, block the small hole of the mud cup gas joint with your index finger, pour into the mud to be tested, the height is better than the sealing ring 2~3 mm A, put the sealing ring, flatten a piece of filter paper, tighten Mud cup cover, then connect the mud cup to the tee fitting, place the 20 ml measuring cylinder under the mud cup, and align the liquid outlet.

★ Slowly rotate the vent valve handle counterclockwise while observing the pressure gauge indication. When the pressure gauge drops slightly or hears the sound of the mud in the mud cup, stop rotating the handle of the vent valve, fine-tune the handle of the pressure reducing valve, so that the pressure gauge indicates 0.69MPa, and the mud cup maintains a constant state of 0.69MPa. A droplet filtrate starts to record, take the cylinder in 30 minutes, exit the pressure reducing valve handle, close the pressure reducing valve, rotate the vent valve clockwise, and release the residual gas in the mud cup. Remove the mud cup, open the mud cup cover and take out the filter paper, wash the floating slurry on the mud cake, and measure the thickness of the mud cake.

★ Rinse and dry the mud cup, cup lid, seal ring (cool dry or dry cup lid filter).

★ Record the amount of water loss in the measuring cylinder. In order to shorten the time, it is generally possible to measure the amount of water lost in 7.5 minutes and multiply it by 2, and if necessary, measure the amount of water loss for 30 minutes.
