In technical transformation of SNG-H300 high-pressure water injection pump ,LT3404 horizontal 3-cylinder single-action plunger pump substitutes original 2-cylinder double-action piston pump to improve technical performances and reliability and increase economic efficiency.

对SNC-H300高压注水泵进行技术改造，用"LT3404卧式三缸单作用柱塞泵"代替原有的双击双作用式二缸活塞泵，以提高技术性能和工作可靠性，提高经济效益。

Emulsion pump is one kind of plunger,mainly as the power of mineral hydraulic pressure bracket,monocase hydraulic pressure stanchion and hydraulic pressure peak stanchion.

乳化液泵是柱塞泵中的一种，主要作为矿山液压支架、单体液压支柱和液压放顶支柱的动力源。

In order to meet the need of economic development for large-specification roll of steel plates, technical improvements have been carried out in the hot-rolling mill. The six sets of high pressure water pump, which cannot provide high enough speed of water supply for rolling, is replaced using three sets of high pressure centrifugal pump. The working mode of three sets of high pressure centrifugal pumps is that two pumps work and another one is spare. After the project has been carried out other problems emerge, for example, the electromotor becoming very heat and the pump being frequently attainted.

为了适应经济发展对轧制大规格的热轧板卷的需要，热轧板厂对轧线进行了技改，将6台不能满足快节奏高速轧制供水的高压柱塞泵更换为3台高压离心泵，三台高压水泵采取两用一备工作状态，投运以来，又出现电机严重发热，泵频繁损坏的问题。

At present, the market is no gas spraying machine, there are two types of pump: piston pump and diaphragm pump.

目前，市场上无气喷涂机泵浦的类型有两种：柱塞泵和隔膜泵。

Such as: dual-diaphragm, double diaphragm pump alarm, special performance pump, high performance piston pump, the product has been overwhelming majority of customers.

双隔膜、双隔膜报警泵、特殊性能泵、高性能柱塞泵，产品得到广大客户的一致好评。

In the down stroke, expansion sleeve recover and there appears a clearance between plunger and pump barrel.

通过有限元力学分析，证明该泵克服了常规柱塞泵摩阻大、效率低、寿命短等不足。

Because of the high sand, high water content, high salinity, high temperature steam heavy oil exploitation, mining and strong polymer injection corrosion media environment factors, piston pump wells pump an average of more and more short-cycle, and some do not even to the required 30 days on the pump seized, severely affected by oil field development.

由于高含砂、高含水、高矿化度、高温蒸气稠油开采、注聚合物开采及强腐蚀的介质环境等因素影响，柱塞泵井平均检泵周期越来越短，有的甚至不到30天就需要检泵，严重影响油田开发。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
