The main purpose of horizontal pipeline pump, what is vertical pipeline pump?

Split box pump (split circulation) is also known as single-stage double-suction centrifugal pump, and its main feature is the large flow rate of the conveying medium. The working principle of the operation of the split case pump: The impeller is installed in the pump casing and fastened to the pump shaft, which is directly driven by the motor.

The pump casing** has a liquid suction connected to the suction pipe. The liquid enters the pump through the foot valve and suction pipe. The liquid discharge port on the pump casing is connected to the discharge pipe.

When the speed of the pump is constant, its pressure head and flow rate are related to the diameter of the impeller. It is widely used in petroleum, chemical industry, electric power metallurgy, mining, ship selection, light industry, agriculture, civil and national defense departments, and occupies an important position in the national economy. Changsha Zhonglian Pump Industry has more than 30 years of experience in the production of Zhongkai pumps, and we have 10,000+ cooperation units, and the selection of **...

Introduction: In the workshop of some factories, there will be circulating water supply equipment, and there is a common component in these equipment, that is, vertical pipeline pumps, especially in the refrigeration industry, glass manufacturing, chemical plants, sewage treatment links, etc., where circulating water supply equipment is most likely to appear. Today, I will give you a brief introduction to the vertical pipeline pump.

1. What is a vertical pipeline pump? According to the name of the vertical pipeline pump, literally means a vertical structure of the pipe, the inner diameter of the water inlet and outlet in the vertical pipeline pump is the same size, on the same horizontal line, the installation of the vertical pipeline pump is very simple, just like our common valve installation, connected between the pipeline and the pipeline, it also contains the foot of the installation, the purpose of the foot is that it can enhance the stability of the vertical pipeline pump. One of the characteristics of the vertical type is that it saves space, and the overall area is much smaller than that of other forms of pipeline pumps, and the investment is relatively low in the construction ranks.

Second, the principle characteristics of the vertical pipeline pump: the centrifugal pump device used in the vertical pipeline pump is combined with the hydraulic model of China's domestic high-tech level, and the designer has designed it on the basis of the ordinary vertical pump, and has developed a multi-functional vertical pipeline pump that can make the vertical pipeline pump along different directions according to different temperatures and different media, including high-temperature resistant vertical pipeline pumps, corrosion-resistant vertical pipeline pumps, vertical pipeline pumps suitable for oily media, etc. These vertical pipeline pumps have the advantages of energy saving, environmental protection, low noise and high performance.

3. The characteristics of vertical pipeline pump products: there is a motor elongated shaft in the vertical pipeline pump, and an impeller is installed on the long shaft on this shaft, the size is short, the structure is tightly connected, and the perfect combination between the generator and the pump valve, which can reduce the wear of the pump valve on its inner diameter and axial direction when rotating, so as to play a role in the stable operation of the pump valve and minimize the noise and vibration. The place of the shaft seal is the use of mechanical seals and seal combinations, most of which are made of titanium alloy sealing rings, medium high-temperature resistant mechanical seals and hard alloy materials, they all have the characteristics of good wear resistance and good sealing, and their organic combination can greatly extend the service life of the vertical pipeline pump.

The installation method of the vertical pipeline pump is simple, and novices can quickly install it successfully when they look at the manual.

The maintenance of the vertical pipeline pump is also very convenient, and there is no need to disassemble the vertical pipeline pump, but to remove the nut on it, and the part to be inspected can be extracted. In the process of using a vertical pipeline pump, the flow part and head part in it are carried out in series or parallel. When installing the vertical pipeline pump pipeline, the vertical pipeline pump can be installed vertically or horizontally according to the requirements of the site. , you can get it for free

1. The appearance is different, the vertical pump is vertical and the horizontal pump is horizontal.

2. The connection form is different, the vertical pump is superimposed from bottom to top, the horizontal pump is arranged longitudinally on the base, the vertical pump is commonly known as the pipeline pump, and the motor and the pump body are connected by sub-ports; The horizontal pump is connected to the motor by coupling, which needs to be aligned regularly.

The vertical pump unit occupies a smaller area than the horizontal pump, and it is not necessary to lay the foundation; The horizontal pump set is equipped with a base to lay the foundation.

4. The difficulty of maintenance is different, and the maintenance of vertical pump is difficult, such as the maintenance of the impeller can only be carried out after all the upper parts need to be removed; Horizontal pumps, on the other hand, are relatively easy, such as IS-type pumps, which can be overhauled by removing the inlet pipe.

5. The installation form is different, the vertical pump is connected as a whole, and the installation is easier; The horizontal pump needs to be adjusted for accuracy after installation.

6. Horizontal pumps have advantages over vertical pumps from an economic point of view.

How a pipeline pump works.

The reason why the pipeline pump can send the water out is due to the action of centrifugal force. Before the water pump works, the pump body and the water inlet pipe must be filled with water to form a vacuum state, when the impeller rotates rapidly, the blades promote the water to rotate quickly, and the rotating water flies away from the impeller under the action of centrifugal force, and the water in the pump is thrown out, and the central part of the impeller forms a vacuum area. The water in Suwon is pressed through the pipe network into the inlet pipe under the action of atmospheric pressure (or water pressure).

In this way, continuous pumping is possible.

The role of the pipeline pump.

1. Pipeline pumps can be used for high-temperature hot water pressurization circulation in heating, boiler and other industries. The operating temperature is below 150 °C.
