A quick share, in one minute, let you understand the selection principles of Zhongkai pumps.

The parallel adjustment method for middle-opening pumps is used when a single middle-opening pump cannot meet the delivery task, allowing for the operation of middle-opening pumps in parallel or series. When two identical centrifugal pumps are operated in parallel, although the head change is minimal, the total delivery flow increases, and the overall efficiency of the parallel pumps is the same as that of a single pump. When pumps are started in series, the total head increases while the flow change is very small. The overall efficiency of series pumps is the same as that of a single pump. After two pumps are connected in parallel, both flow and head increase, but due to the limitations of the pipeline characteristic curve, pipeline resistance increases, resulting in a total delivery volume that is twice that of the original single pump. After two pumps are connected in series, both head and flow will also increase, but...

How to choose a chemical process pump?

As a key piece of equipment in chemical engineering processes, chemical process pumps are receiving increasing attention. Due to the complex characteristics of chemical media and the continuously rising demands from users, how should we, as manufacturers, make our selections? What should we focus on? These questions are particularly important. Let's take a look at how to choose chemical process pumps. Below is a brief review of the selection of commonly used chemical pumps, hoping to assist colleagues in this field in their work.

Selection of long shaft pumps

The long shaft pump is a type of centrifugal pump. From the perspective of centrifugal pumps, the performance of liquid pumps has been improved, making it far superior to liquid pumps and operating more stably. Based on market demand, the company has developed the VT series long shaft deep well pump, which is widely used in industrial enterprises such as water supply companies, sewage treatment plants, power plants, steel mills, and mines, as well as in municipal water supply and drainage, flood control, and urban waterlogging projects.

Introduction to Long Shaft Pumps

Long-axis pumps are suitable for transporting strip-shaped particles, high viscosity, strong acids, alkalis, salts, strong oxidants, and other corrosive media. The newly developed underwater pumps are suitable for enterprises to transport various lightweight media that are flammable and explosive. The casing, outlet pipe, and flow components of traditional underwater pumps are all made of corrosion-resistant materials. The motor part is located at the liquid surface, while the pump part is located below the liquid surface. The pump body, motor, and flow components of the new underwater pump are all made of special materials. The motor part is coaxially connected to the pump part and is located below the liquid surface.

The use and installation of long shaft pumps

The long-axis pump determines maintenance projects based on the data from the operation technology development status monitoring system, conducts preventive inspections according to cycle management, and analyzes, repairs, or replaces defective components. When disassembling and replacing major components, it should comply with the main maintenance quality standards.

Introducing the vertical long shaft pump

The length of the long-axis pump is reasonable, and the stiffness is sufficient. The design of the pump's water delivery pipe can incorporate a flange connection, with a guide bearing body between two adjacent sections of the water delivery pipe system.

Long shaft pump manufacturer: Introducing information about long shaft pumps.

Long shaft pumps are mainly used for transporting clean water, wastewater containing certain solid particles (such as iron filings, sand, coal powder, etc.), corrosive industrial wastewater, and seawater; the temperature of the transported liquid does not exceed 80°C. They are widely used in primary water treatment plants, sewage treatment plants, the metallurgy and steel industry (especially in industries that transport oxidized iron scale in rotary water pools), power plants, mines, municipal projects, and agricultural irrigation projects. Long shaft pumps are primarily used in power plants and chemical plants, and are sometimes used in deep wells. They are also used in municipal, papermaking, drainage, and other enterprises.
