查询词典 Venturi

The production line for both three layer PE pipe and epoxy powder inner anticorrosion pipe came from the reformation of an original production line of three layer PE pipe. The main problems to have been solved are as follows, convert the conventional spray gun deflector into two parts of diversion nozzle and gun wick to suit for different pipe diameters; adopt two stage retrieval equipment to increase powder retrieval rate and improve work environment; enlarge the calibres of gas jet and Venturi pump jet to increase powder output 20% above to ensure the spry coating thickness; design gun pushing device to raise automatic production level.

三层PE管和环氧粉末内防腐管兼容生产线是在三层PE管生产线的基础上改造而成的，主要解决了如下技术问题：将常规使用的喷枪导流体改成导流嘴和枪芯两部分，以适应喷涂不同直径钢管的需要；采用双级回收装置，提高粉末回收率，改善作业环境；加大一次气喷嘴和文丘里泵喷嘴的口径，使出粉量增加20%以上，从而保证涂层喷涂的厚度；设计推枪装置，提高生产的自动化程度。

Top-level performances, small dimensions premium quality are some of the amazing features of the new compressed air vacuum A15. Close-up of the Venturi system: small and quiet, neatly tucked under the vacuum head. This machine has 25 liters capacity: the container on castors, has a new release system.

A15型压缩空气式真空吸尘机适合在没有电源的工作环境或禁止用电情况下使用，是唯一的能进行清理并从所处的环境中吸尘的机器，在化工，喷漆，钢铁，精炼厂等行业都非常适用。

According to the existent problem of the running water film deduster which included the more pressure drop and the efficiency of low removal dust,the method was discussed by applying venturi and rotating-stream-tray and spraying and demister to reconstruct the old deduster.

针对文丘里水膜除尘器运行中存在的压降过大和除尘效率过低等问题，采用文丘里+旋流板+喷淋+折流除雾器的方法对原有除尘器进行改造。改造工程应用表明，该方案的阻力和除尘效率在理论上的分析与实际应用相一致，在文丘里喉管气速 40m/s，液气比 0 。5L/m3 ，喷淋液气比为 1.5L/m3 时，除尘效率达到 95 %以
