Introduction of relevant knowledge of single suction pump

Single suction pump bearing factory has added grease, should check the bearing before starting. If impurities enter the bearing during transportation and storage, or if the grease solidifies or leaks, the grease must be replaced before starting.

How much do you know about single suction pumps?

In the selection process of single suction pump, the parameters and pump performance after determining the pump type are the problems that buyers need to confirm and pay attention to. Because each company's single suction pump model is not the same, the parameters and performance are not the same, so it is still necessary to shop around and choose the right open pump.

The structure of the open pump is introduced, come and collect!

What is the structure of the middle pump? The suction inlet and outlet of the single-stage pump are under the pump axis, and the horizontal direction and the axis are in a vertical position and the pump shell. In the middle, there is no need to disassemble the water inlet during maintenance, the discharge pipe and the motor (or other prime mover) look from the coupling to the direction of the pump, the pump is rotated in the direction of the reverse inch needle, such as according to the special order needs of users can also be changed to the clockwise inch needle rotation. The main components of the single stage pump are: pump body, pump cover, impeller, shaft, double suction sealing ring, shaft sleeve, bearing and so on. In addition to the use of high-quality carbon steel shaft, the rest of the cast iron. The pump body and the pump cover constitute the workshop of the impeller, and the inlet and outlet water flange is provided with a pipe screw hole for installing the vacuum gauge and pressure gauge, and the lower part of the inlet and outlet water flange is provided with a drain pipe screw hole.

Dry goods share, one minute to take you to understand the operation of the pump working principle

Middle open pump, also known as single stage double suction centrifugal pump, is characterized by large flow of conveying medium. What is the operating principle of the central pump? Let's take a look at this briefly:

The parallel adjustment mode of the central pump is that when a single central pump can not meet the transmission task, the central pump can be operated in parallel or in series. Two centrifugal pumps of the same type are parallel, although the pressure head changes little, the total transport flow increases, and the total efficiency of the parallel pump is the same as that of a single pump. When the pump starts in series, the total pressure head increases and the flow rate changes little. The total efficiency of a series of pumps is the same as that of a single pump. After the two pumps are connected in parallel, the flow and pressure head increase, but due to the limitation of the pipeline characteristic curve, the pipeline resistance increases, and the total throughput after the two pumps are connected in parallel is twice that of the original single pump. After the two pumps are connected in series, the pressure head and flow rate will also increase, but the total pressure head after the two pumps are connected in series is still less than twice the original single pump.

How to choose a chemical process pump?

How to choose a chemical process pump?

As a key equipment of chemical process, chemical process pump is also more and more people's attention, due to the complex characteristics of chemical media, as well as the continuous improvement of user requirements, as a manufacturer, how should we choose? What should we focus on? And so on is particularly important. Let's take a look at how to choose the chemical process pump? The selection of commonly used chemical pump is briefly reviewed, hoping to help colleagues in this field to do better work.

Selection of long shaft pump

Selection of long shaft pump

Long shaft pump belongs to a centrifugal pump, from the point of view of the centrifugal pump, that is, the performance of the liquid pump has been improved, so that its performance is much higher than that of the liquid pump, and the operation is more stable. According to the market demand, the company has developed VT series long shaft deep well pumps, which are widely used in water supply companies, sewage treatment plants, power plants, steel mills, mines and other industrial enterprises, municipal water supply and drainage, flood control, waterlogging and other projects.
