管道增压泵选型要注意写什么?

随着科技进步管道增压泵在我们的日常中中大量使用,相信大家对于管道增压泵一定不会陌生,管道增压泵指的就是安装在管线路上的增压泵。在管道增压泵安装上并不会局限于指某一种类或型号的泵,管道增压泵种类繁多如立式多级离心泵、立式单级离心泵、卧式单级离心泵、卧式多级离心泵、自吸式离心泵等种类。
With the progress of science and technology, pipeline booster pump is widely used in our daily life. I believe you will not be unfamiliar with pipeline booster pump. Pipeline booster pump refers to the booster pump installed on the pipeline. The installation of pipeline booster pump is not limited to a certain type or model of pump. There are many kinds of pipeline booster pumps, such as vertical multi-stage centrifugal pump, vertical single-stage centrifugal pump, Horizontal single-stage centrifugal pump, horizontal multi-stage centrifugal pump, self-priming centrifugal pump, etc.
管道增压泵-介绍
Pipeline booster pump - Introduction
管道增压泵在实际使用中对流量以及输送介质都没有太高要求,因此在管道增压泵型号选择上要充分考虑流量、给排水等性能是否合适,依据工艺流程,给排水要求进行选择。在对管道增压泵选择上应从液体输送量、液体性质、管路布置、装置扬程、操作运转条件等进行。管道增压泵绝大部分采用离心泵。在操作上具有制造技术成熟、性能范围广、使用维护方便、操作方便可靠、调节维修容易、易于实现自动化和远距离操作、转速较高等众多优势。
The pipeline booster pump does not have high requirements for flow and transmission medium in actual use. Therefore, in the selection of pipeline booster pump model, it is necessary to fully consider whether the flow, water supply and drainage and other performance are appropriate, and select according to the process flow and water supply and drainage requirements. The selection of pipeline booster pump shall be carried out from liquid delivery capacity, liquid properties, pipeline layout, device head, operation conditions, etc. Most pipeline booster pumps use centrifugal pumps. In operation, it has many advantages, such as mature manufacturing technology, wide performance range, convenient use and maintenance, convenient and reliable operation, easy adjustment and maintenance, easy automation and remote operation, high speed and so on.
管道增压泵-基本数据
Pipeline booster pump - basic data
在使用管道增压泵时对于其型号选择尤为重要,在管道增压泵型号选择中一定要充分了解管道使用介质特性、比重、介质名称、腐蚀性、粘度、毒性等。介质中所含固体物的颗粒直径含量情况,同时介质温度也是十分重要的一点。管道增压泵所需要的流量在工艺流程中可以忽略管道系统中的泄漏量,但需要注意必须考虑管道增压泵的工艺变化对流量产生的影响。如果是农业用管道增压泵要采用明渠输水时,还要考虑渗漏及蒸发量。
When using pipeline booster pump, it is particularly important to select its model. In the model selection of pipeline booster pump, we must fully understand the characteristics, specific gravity, medium name, corrosivity, viscosity and toxicity of pipeline medium. The particle diameter and content of solids in the medium, and the medium temperature is also very important. The flow required by the pipeline booster pump can ignore the leakage in the pipeline system in the process flow, but it should be noted that the impact of the process change of the pipeline booster pump on the flow must be considered. In case of agricultural pipeline booster pump, leakage and evaporation shall also be considered when open channel water transmission is adopted.
管道增压泵-流量
Pipeline booster pump - flow
在管道增压泵生产工艺中已经给出了较小、正常、较大流量等数据,应按较大流量进行考虑。如果生产管道增压泵工艺中只给出正常流量,应考虑留有一定余量。对于ns>100的大流量低扬程管道增压泵,流量余量应取5%,对ns<50的小流量高扬程管道增压泵,流量余量应取10%,在50≤ns≤100之间的管道增压泵,流量余量也取5%,一些质量低劣或是运行条件恶劣的管道增压泵,流量余量应取10%。如果基本数据只给出了重量流量,应换算成体积流量进行制作。

The data of small, normal and large flow have been given in the production process of pipeline booster pump, which should be considered as large flow. If only the normal flow is given in the production pipeline booster pump process, a certain margin shall be considered. For the large flow and low head pipeline booster pump with NS > 100, the flow margin shall be 5%. For the small flow and high head pipeline booster pump with NS < 50, the flow margin shall be 10%. For the pipeline booster pump between 50 ≤ ns ≤ 100, the flow margin shall also be 5%. For some pipeline booster pumps with poor quality or poor operating conditions, the flow margin shall be 10%. If only the weight flow is given in the basic data, it shall be converted into volume flow for production.
管道增压泵-分类
Pipeline booster pump - Classification
随着科技进步,对于管道增压泵需求量也子在不断提升,使得管道增压泵种类繁多,按照管道增压泵原理可分为:旋涡式、离心式、射流式管道增压泵,按照结构可分为:立式单级、卧式单级、立式多级、卧式多级、自吸式管道增压泵,按照材质可分为:HT200铸铁、SUS316不锈钢、SUS304不锈钢、H62黄铜管道增压泵,按用途可分:生活、空调、消防、制冷、化工管道增压泵。在管道增压泵实际使用时可根据需要进行适当选择。
With the progress of science and technology, the demand for pipeline booster pump is also increasing, resulting in a wide variety of pipeline booster pumps. According to the principle of pipeline booster pump, it can be divided into vortex type, centrifugal type and jet type pipeline booster pump. According to the structure, it can be divided into vertical single-stage, Horizontal single-stage, vertical multi-stage, horizontal multi-stage and self-priming pipeline booster pump. According to the material, it can be divided into HT200 cast iron SUS316 stainless steel, SUS304 stainless steel and H62 brass pipeline booster pumps can be divided into: domestic, air conditioning, fire fighting, refrigeration and chemical pipeline booster pumps. When the pipeline booster pump is actually used, it can be properly selected according to needs.
管道增压泵-注意事项
Pipeline booster pump - precautions
在管道增压泵型号选择时要选择合理的管道直径,管道直径较大,在相同流量时液流速度小,同时阻力损失小,管道增压泵价格较高,如果管道增压泵管道直径较小,会导致阻力损失加大扬程增加,从而配带功率增加,使得管道增压泵使用成本和运行费用都有所增加。管道增压泵的排出管及管接头应考虑其所能承受较大压力。在管道增压泵的管道布置上应尽可能采用直管布置,这样可以有效的减小管道中附件和缩小管道长度。
When selecting the model of pipeline booster pump, it is necessary to select a reasonable pipeline diameter. The pipeline diameter is large. At the same flow rate, the liquid flow speed is small, the resistance loss is small, and the price of pipeline booster pump is high. If the pipeline booster pump has a small pipeline diameter, it will increase the resistance loss, increase the head, and increase the matching power, The use cost and operation cost of pipeline booster pump have increased. The discharge pipe and pipe joint of pipeline booster pump shall consider the large pressure it can bear. In the pipeline layout of pipeline booster pump, straight pipe layout shall be adopted as far as possible, which can effectively reduce the accessories in the pipeline and reduce the length of the pipeline.
