  1. This drilling adopts crank connecting link and walking beam percussion mechanism, which make the drilling possess two percussive functions, normal drilling takes connecting link impact as main mode, when encountering special situation and the connecting link impact can not drill, it can transform into hoisting impact, the stroke length can be modulated, it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism, these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag, which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum, but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist, which not only ensures the balance state of drilling tool, but also reduces the mechanical design, and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising, and reduces the assistant operating time

    該鉆機採用曲柄連桿、游梁式沖擊機構，使鉆機具有兩種沖擊功能;正常鉆進以連桿沖擊為主，遇到特殊情況，用連桿沖擊不能鉆進時，可轉為卷揚沖擊，沖程可調，因連桿沖擊機構連續工作，所以實現了自動沖擊鉆進，可提高鉆進效率，減輕勞動強度;採用泵吸反循環的方式排渣，既能有效解決卵礫石地層、堅硬地層等特殊地層鉆進的困難，又很好地解決了沖擊鉆機效率低下的問題;採用直齒圓柱齒輪差速機構作為主卷揚的雙筒同步機構，既保證了鉆具處于平衡狀態，又大大簡化了該機構設計，降低了成本;該鉆機底盤行走移位採用步履式;鉆塔採用液壓起立，減少了輔助作業時間。
  2. Maximum operating pressure differential

    最大工作壓差
  3. Service conditions - line media, temperature, and maximum operating differential pressure

    應用環境-管路流體介質，溫度和最大工作壓差。
  4. Choose models according to max oprating temperature, max oprating pressure, max operating differential pressure that listed the parameter table

    用戶根據用汽設備的最大用汽量（乘以選用倍率系數2 - 3倍） ，最高工作壓力、最高工作溫度、最高工作壓差對照表中參數選型。
  5. The most common method of determining maximum differential pressure across the valve seats is to assign the maximum design or operating pressure the upstream value p1 and assume a downstream pressure p2 of 0 psig

    測定閥門閥座的最大壓差的最常用方法是將最大設計或工作壓力作為上游的壓力值p1 ，然後假定下游壓力值p2為0psig
  6. Operating pressure differential
