pump barrel
常见例句
- One effective way is preferred pump barrel and plunger of materials and surface treatment processes.
其中一个有效的方法就是优选泵筒和柱塞的材料和表面处理工艺。 - The bending of pump barrel will not happen as low part fixed pumping piston going downward that only happens when it works in heavy oil well.
而泵筒下部固定泵柱塞上行时,泵筒不会发生弯曲,只是其柱塞在稠油井中下行时泵筒才会发生纵向弯曲。 - The pump barrel is treated with a special boriding technology and the plunger is coated with nickel alloy, therefore the pump has excellent corrosion- and wear-resistance.
为此,设计了一种适用于大斜度井和水平井的新型斜井抽油泵。这种泵的泵筒采用特殊的固体渗硼工艺,柱塞采用热喷焊镍基合金工艺,防腐且耐磨性优越; - Light, sweet crudes are cheaper to pump, transport, and distill and produce more gasoline per barrel than other types of crudes so it generally goes for more dollars per barrel than others.
FORBES: British Government Faces Up To Peak Oil - Sweet light crude oil yields the most gallons of gasoline per barrel of oil and since it has low viscosity and low density, it is comparatively inexpensive to pump, transport, and refine.
