查询词典 low pressure

When the external control pressure increases to the shutoff pressure setting point of the valve, the external control pressure acting on the underside of the diaphragm, which breaks the balance of the compression of the pressure spring and the latch lever, triggers the latch and disengages valve disc arm from the latch.

Turn it back on and set the box cover at the right, and then set the pumb output tubes and machine into the tubing connected, and then on the machine: the pumb work grow up immediately, and mold hold its output tube is also apparent from inside the pent up spilling in output occurred at both the reliability and vibration grow up; then view the instructions in the oil pressure table has been rising "" 0 to "" 5, at the same time, pressure relay (and by keeping the switchboard AC closing in — from its contact outgoing voltage) order lubrication solenoid valve work of fuel, oil pressure decreased and quickly rose to require lubrication with pressure-a solenoid valve, so self-repeating.

重陈不兵其拧不松并不兵盒盖上好，再不兵油泵输入惯与机械的不退油惯接开，然后试机：油泵处事的声音当即变不小了，且用手捏握其输入惯也暗显感触边面流油的鼓胀度和震不不静度均变不小了；再不雅油压外洋的辅导已由&0&逐步上降到了&5&，与此同时，不张力继电器不不静息（并开功使配电柜内互换隔绝器呼分——由其触不面传不入电压）令润滑电磁阀处事——放油，油压回降后又迅不缓上降至规矩不张力后再令润滑电磁阀放油，如此轮回来往。

Fluidization and Sounding Pressure Characters Experimental Research on Pulsating Fluidized Bed After verifying experimentally the Rijke type self-exciting pulsating fluidized bed combustion, under different operating conditions (different empty cross-section wind speed and inaction bed height), experimental research the oscillation characters of sounding pressure in the pulsating fluidized bed. The results indicate that the sound characters in the Rijke type self-exciting pulsating fluidized bed combustor are the same with it in the Rijke type combustor, the pressure in the combustor oscillate up and down in the sinusoidal manner and the pressure is the superposition of the multiple harmonic waves.

脉动流化床流化与声学压力特性实验研究在实验验证了Rijke型自激脉动流化燃烧概念后，在不同运行条件(空截面风速、静止床层高度)下，实验研究了Rijke型自激式脉动流化床的声压振动特性，研究结果表明：脉动流化床内建立起的声波特性和Rijke型脉动燃烧器内的一样，各点压力呈正弦规律上下振动，且压力是基波幅值最大的多次谐波的叠加。

At initial time the core is saturated by oil or water,and put the core into a sample holder with two pressure transducers at ends;Then make the core in a high pressure condition and shut-in the ends of holder;After the pressure of core is steady,open one end of holder to one certain pressure,in the same time, measure the pressurd of sealed end,until attain to another balance state.

设计实验方法为：初始时刻，将岩心在高压下饱和原油，在一端封闭，并装入测压计，待系统压力平衡且稳定后，将岩心另一端放空至某一压力值，连续测量封闭端压力变化，直至系统达到稳定状态。

Turbines are equipped with safety devices for pressure,live steam pressure,extraction steam pressure vacuum,axial displacement of rotor,and the monitoring devices for speed,vibration,temperation,pressure etc.
