工厂如何选择合适的高压泵。

How the factory chooses the appropriate high pressure pump.

在工业生产中对于一些客户来说，选择一台高压清洗机主要看它的工作压力的大小，总是有人觉的工作压力大的就好，往往忽略了工作流量。

In industrial production in industrial production, choosing a high-pressure cleaning machine mainly depends on the size of its working pressure.

工厂如何选择高压清洗机，需要考虑的因素还是有很多种的，比如说工业环境，日常使用的频率，清洗常见物体的表面等，这都是决定购买一台高压清洗机之前要考虑的内容。

There are still many factors to be considered in how the factory chooses the high pressure cleaning machine, such as the industrial environment, the frequency of daily use, the cleaning of the surface of common objects, and so on. This is to be considered before deciding to buy a high pressure cleaning machine.

一、高压清洗机主要有两个参数：一个是工作压力，一个是单位时间的工作流量。

First, the high-pressure cleaning machine has two main parameters: one is the working pressure, the other is the working flow per unit time.

总的来说一台高压清洗机的工作流量和工作压力一样的重要的参数，同样是一台800bar高压清洗机，如果它们的工作流量不同，那这两台800 bar高压清洗机的输入功率也相差很大，从这就可以看出它们的区别。

Overall, the working flow of a high-pressure cleaning machine is as important as the working pressure. It is also an 800 bar high-pressure cleaning machine. If their working flow is different, the input power of the two 800 bar high-pressure cleaning machines also varies greatly. From this we can see their difference.

在清洗同样的物体时，同一工作压力的二台机器流量大的工作效率要快好多。

When cleaning the same object, two machines with the same working pressure work much faster.

二、那么在什么情况下要用大流量的高压清洗机比较好呢?

Second, so under what circumstances to use a large flow of high-pressure cleaning machine is better?

一般用来做管道疏通时，流量大的反推力也比较大，这样疏通的管道的长度才能长。

Generally used to do pipeline dredging, large flow back thrust is also relatively large, so that the length of the pipeline can be long.

还有就是要进行大面积高强度清洗时，工作流量大会大大提高工作面清洁的工作效率。

There is also a large area of high-strength cleaning, the working flow conference greatly improve the working efficiency of working face cleaning.

总之一般在一样的工作压力下，流量大的高压清洗机工作效率会比流量小的要快很多。

In short, under the same working pressure, the high-pressure cleaning machine with large flow rate will work much faster than the flow rate.

但流量大的高压清洗机，能耗也比较大，如果同样的机器流量大的机器的能耗要高出20%左右。

But the highpressure cleaning machine with large flow rate, energy consumption is also relatively large, if the same machine with large flow rate machine energy consumption is about 20% higher.

在具体的使用过程中，就要求各使用者根椐不同的要求来选好自已的高压清洗机的工作压力及流量，而不是只看工作压力而不注重工作流量，往往这样选择的机器会很影响工作效率，三、除了要考虑高压清洗机的压力和单位时间流量以外，还有喷嘴和枪杆等需要考虑的因素。

In the specific process of use, each user is required to select the working pressure and flow rate of their own high pressure cleaning machine according to different requirements, rather than only looking at the working pressure and not paying attention to the working flow rate.

选择合适的高压清洗设备不仅可以高效的完成清洗目的，而且成本合理;而不合适的设备可能损伤被清洗物体，还会增加不必要的费用。

Choosing the appropriate high pressure cleaning equipment can not only accomplish the cleaning purpose efficiently, but also the cost is reasonable, and the improper equipment may damage the cleaned object and increase the unnecessary cost.

四、在以往的高压清洗作业过程中，人们往往忽视了对出水高压软管的选择，认为高压水在软管中的损失不大，不会影响清洗效果而真的是这样吗。

Fourth, in the past high-pressure cleaning process, people often ignore the choice of high-pressure hose for effluent, think that the loss of high-pressure water in the hose is not large, will not affect the cleaning effect, but really so.

在满足作业工作面的情况下，高压软管总长度要尽量缩短，一般不超过30m而单根软管长度一般应大于5m，减少接头数量。

When the working face is satisfied, the total length of the high pressure hose should be shortened as far as possible, generally not more than 30 m and the length of the single hose should generally be greater than 5 m, to reduce the number of joints.

五、另外高压清洗机喷嘴的选择也至关重要。

In addition, the choice of nozzle of high pressure cleaning machine is also very important.

广泛使用的喷嘴有扇形喷嘴和锥形喷嘴。

The widely used nozzles are nozzles and conical nozzles.

扇形喷嘴在低于15Mpa的压力下工作有较高的清洗效率;而锥形喷嘴工作压力在15～30 Mpa范围内较适宜。

The fan nozzle has higher cleaning efficiency under the pressure of less than 15 Mpa, while the conical nozzle working pressure is more suitable in the range of 15~30 Mpa.

购买合适的高质量高压清洗机要进行参数的全面考量，以实现应用目的，而合理添加配件可以使高压清洗机具有更大的应用范围和功能。

The purchase of suitable high-quality high-pressure cleaning machine should be considered comprehensively in order to achieve the purpose of application, and the reasonable addition of accessories can make the high-pressure cleaning machine have a and function.
