suction pressure造句
(1) If suction pressure must be higher than the atmosphere. (2) Check that suction pressure is normal. (3) The performance under the fixed suction pressure for a triple-evaporator air conditioning system(AC) was studied. (4) Also discussed are the effects of suction pressure and impeller vane number. (5) The valve controls the suction pressure of a compressor in response to external input signal, ensuring minimum compressor operation and lower power consumption. (6) If suction pressure is strong enough, the unsteady vortex shedding phenomenon can be eliminated and steady flow formed. (7) The suction pressure drop loss, discharge pressure drop loss, suction temperature increase loss, and mass flow leak loss were analyzed quantitatively. (8) The compressor speed was regulated to keep the suction pressure constant when the operating conditions were changed. (9) Low suction pressure results in recirculation in the suction chamber, which will influence the security of the ejector refrigeration system. (10) The drop of suction pressure which is caused by flowing obstruct of linked tube leads to serious influence to refrigerant density. (11) When studying membrane fouling, the increasing rate of suction pressure of membrane was used to evaluate the membrane filtration characteristics of membrane bioreactor process. (12) However, fixing suction pressure can eliminate the interaction among different units and therefore aid to realize the independent control of individual units. (13) A positive suction pressure on the main pumps usually is needed and is frequently supplied by booster pumps close to the tanks. (14) The higher the suction pressure, the greater the dynamic invalid control, while the less effective ventilation. (15) This might be used in blending application , or in situations where suction pressure varies and cavitation control is sought. (16) The problem of methane effusing from the adjacent stratum during normal mining stage could be resolved only by the suction pressure of the high-position alley. (17) The results show that EPR method can solve the suction pressure fluctuant problem of compressor well but can not decrease the refrigeration temperature effectively. (18) The indoor temperatures were taken as the controlled variables to regulate the openings of individual EEV and the suction pressure was taken to modulate the speed of compressor. (19) The results showed that: with the operating temperature and suction pressure increasing, the fresh water production would raise either, as well as energy consumption. (20) When the discharge pressure keeps constant, the relationship between displacement of valve rod and suction pressure, wobble plate case pressure, flow rate through control valve have been obtained.
