CRT as a booster pump and transfer pump sea water treatment and other abrasive liquids, reliable performance, and in the industry with the most extensive product line, flow up to 2200 l / h, pressure head of up to 250 meters ( specially designed high-pressure pump up to 450 meters).

CRT泵在作为增压泵和传送泵处理海水和其它磨蚀性液体时，性能可靠，而且在该行业中具有最广的产品系列，流量最高可达2200 l/h，压头最高为250米（特制的高压泵可达450米）。

According to the service conditions of users, it can be fitted with vacuum booster pump, and this pump will be used as a prepump.

根据用户使用情况，可配备真空增压泵，将该泵做为前级泵，由增压泵的抽气力加强，前级泵连续抽除，能使您的设备获得更高的真空。

Third, in the industrial area of the screw pump for lubrication pump, the hydraulic system for hydraulic pumps, the fuel system for the transmission and the booster pump; in the pipeline for the transportation system and pumps.

三螺杆泵在工业领域中作润滑泵，在液压系统中作液压泵，在燃油系统中作输送及增压泵；在输油系统中作输送及加油泵。

Check if the above still does not resolve, you can check the pump apart to see whether the broken shaft, but also check the pump ring, stationary ring is intact, the possibility of a small amount of rotor axial movement.

通过以上检查若仍不能解决，可将泵拆开检查，看泵轴是否折断，还应检查泵的动环、静环是否完好，整个转子可否少量轴向移动。

This paper describes the test results of the effects of the angle and clearance of fixed guide blade on the performances of mixed flow pump.

对混流泵固定导叶安放角及叶轮轮缘与泵体前盖间隙变化对泵性能影响的试验结果作了介绍。

In this article,on designing PRB7-200/100/25/31 emulsion pump,we adopt the design method of two_stage flow,which adopts stage columnar plug structure and two_stage flow method.

以PRB7— 2 0 0 / 10 0 / 2 5 / 31 5型乳化液泵为例，介绍一种二级流量泵的设计方法，该泵采用阶梯柱塞结构，两级供液方

The hydraulic loss of conduit in both vertical pump system and bulb tubular pump system were calculated using the numerical simulation, and the influence of pump impeller diameter on hydraulic loss of conduit was analyzed. Based on the similitude rules of impeller pump, the relationship between pump impeller diameter and nD value and the influence of pump selection and design were analyzed.

采用数值计算的方法，分别计算了具有不同水泵叶轮直径的立式轴流泵装置和灯泡贯流泵装置的流道水力损失，比较了水泵叶轮直径对流道水力损失的影响；根据叶片泵的相似律，分析了在一定设计流量条件下水泵叶轮直径与nD值的关系以及对水泵选型设计的影响。

It is could be concluded that the larger pump impeller diameter may obviously increase the efficiency of both conduit and pump system; increasing pump diameter and decreasing its rotational speed is consistent with reducing nD value.It is suitable to pump system with low head to choose lower nD value, so as a hydraulic model of axial flow pump with the better hydraulic characteristics could be obtained.

结果表明：选取较大的水泵叶轮直径将显著提高流道效率和泵装置效率；&增径降速&与降低nD值是一致的；在泵装置扬程较低的情况下，选取较小的nD值便于选用到水力性能较好的轴流泵水力模型。

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。

They combine the working characteristics of a plunger pump with the sealing advantages of a diaphragm pump.

此系列计量泵具有活塞泵工作性能和隔膜泵的密封特性。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
