Second, the main technical parameters:

★ internal diameter of the instrument: 50mm

★Test tube height: 200mm

★Water storage room: 20mm

★ bleeding port diameter: 10mm

★ Filter diameter: 0.08mm

★ Aluminum alloy case with pressure gauge

三、试验方法：

★查看顶盖与座内是否有密封圈并拧紧各螺丝后检查容器是否漏气.

★浆搅拌均匀的浆液在自加水开始的7min内倒入容积为400ml的压力容器过滤漏斗中。倒入浆液体积为200ml。安装并旋紧上端盖子，静置10min，上端连接压缩空气，开启压缩空气阀，迅速加压至试验压力。保持试验压力5min后，关闭压缩空气阀卸压，使漏斗下部泌水管中的泌水全部流出，记录泌水体积精确至0.2ml。

压力泌水率按下式计算：

压力泌水率=泌水量/200mlXA

★蜗轮箱内应定期注黄干油,保持润滑.

Third, the test method:

★ Check if there is a seal ring in the top cover and the seat and tighten the screws to check if the container leaks.

★ The slurry with a uniform slurry was poured into a pressure vessel filter funnel with a volume of 400 ml within 7 min from the start of the addition of water. Pour the slurry into a volume of 200 ml. Install and tighten the upper end cover, let stand for 10min, connect the compressed air to the upper end, open the compressed air valve, and quickly pressurize to the test pressure. After the test pressure was kept for 5 minutes, the compressed air valve was closed to relieve the pressure, so that the bleeding water in the lower part of the funnel was discharged, and the bleeding volume was recorded to 0.2 ml.

The pressure bleeding rate is calculated as follows:

Pressure bleeding rate = bleeding volume / 200mlXA

★ The worm gear box should be regularly filled with yellow dry oil to keep it lubricated.
