中开泵怎么选型

date.png 2020-03-16 10:48:31

中開泵又稱之爲單级雙吸式離心泵,其主要特徵爲保送介質的流量大,當泵的转速一定時,其壓頭、流量與葉轮直径有關。接下來小编就给大傢引见一下中開泵選型步骤,希望在您購買的時候會對您有所幫助!

一、列齣中開泵根本數據:  包括:介質的特性,介質中所含因體的颗粒直径、含量几、介質温度、所需求的流量壓力管道係统數據。

二、確定流量扬程:

1、假如生產工藝中已给齣小、正常、大流量,應按大流量考慮。

2、假如生產工藝中隻给齣正常流量,應考慮留有一定的餘量。  對于ns>100的大流量低其不意扬程泵,流量餘量取5%,對ns<50的小流量高扬和泵,流量餘量取10%,50≤ns≤100的泵,流量餘量也取5%,對質量低劣和運行條件噁劣的泵,流量餘量應取10%。

3、假如根本數據隻给重量流量,應换算成體積流量。

Zhongkai pump is also known as single-stage double suction centrifugal pump. Its main feature is the large flow of guaranteed medium. When the pump speed is fixed, its head and flow are related to the impeller diameter. Next, I will introduce the selection steps of Zhongkai pump to you. I hope it will help you when you buy it!


1、 List the basic data of Zhongkai pump:


Including: characteristics of medium, particle diameter, content, medium temperature and required flow and pressure pipe system data of the factor contained in the medium.


2、 Determine flow head:


1. If the minimum, normal and maximum flow have been given in the production process, the maximum flow shall be considered.


2. If only the normal flow is given in the production process, a certain margin should be considered.


For the pump with large flow and low head, the flow margin is 5%. For the pump with small flow and high head, the flow margin is 10%. For the pump with 50 ≤ ns ≤ 100, the flow margin is 5%. For the pump with poor quality and poor operation conditions, the flow margin is 10%.


3. If the basic data only gives weight flow, it should be converted into volume flow.
