1. Overview.
Single-stage, single-suction vertical centrifugal pump is a common industrial pump, which is widely used in various conveying occasions. It has the characteristics of simple structure, convenient operation and low maintenance cost, and is widely used in chemical, petroleum, pharmaceutical and other fields. This article will introduce the structure, working principle, characteristics and application of single-stage single-suction vertical centrifugal pump in detail.
Second, the structure. The single-stage, single-suction vertical centrifugal pump is mainly composed of pump body, impeller, pump cover, shaft and bearing. The pump body is the main body of the pump, and there are flow channels inside for transporting liquids. The impeller is the heart of the pump, and the centrifugal force generated by rotation causes the liquid to be thrown from the center of the impeller to the edge, creating pressure. The pump cover is fixed on the pump body and fits with the impeller to form a sealing cavity to prevent liquid leakage. Shafts and bearings are used to support and transmit torque.
Third, the working principle.
The working principle of a single-stage, single-suction vertical centrifugal pump is mainly based on the action of centrifugal force. As the impeller rotates, the liquid is flung from the center of the impeller to the edge, creating a certain pressure. Under the action of centrifugal force, the liquid is thrown out and flows upwards along the flow path in the pump body, so as to realize the delivery of the liquid. During the conveying process, the pressure and flow rate in the pump are increased accordingly.
Fourth, features. The single-stage, single-suction vertical centrifugal pump has the following characteristics:
1.Simple structure: The structure of the single-stage single-suction vertical centrifugal pump is relatively simple, which is easy to maintain and maintain.
2.Easy to operate: The pump is simple to operate, and only needs to open and close the valve to achieve liquid transfer.
3.Low maintenance cost: Due to its simple structure, the maintenance cost is relatively low.
4.Strong adaptability: Single-stage single-suction vertical centrifugal pump is suitable for a variety of different conveying occasions, and can be selected according to actual needs.
5.High efficiency and energy saving: The pump has high efficiency and remarkable energy-saving effect, which can save energy costs for enterprises.
5. Application. Single-stage single-suction vertical centrifugal pumps are widely used in chemical, petroleum, pharmaceutical and other fields. In the chemical industry, the pump can be used to convey corrosive liquids such as acids, alkalis, salts, etc. In the petroleum industry, the pump can be used to convey oil products such as **, lubricating oil, etc. In the pharmaceutical industry, the pump can be used to transport pharmaceutical raw materials, liquid medicines, etc. In addition, the pump can also be used in food, environmental protection and other fields.
6. Summary. As a common industrial pump, single-stage single-suction vertical centrifugal pump has the characteristics of simple structure, convenient operation and low maintenance cost, and is widely used in various fields. Understanding its structure, working principle, characteristics and application will help you to better select and use the pump, improve your production efficiency and save energy costs. In the future, with the continuous progress of technology and the continuous improvement of application requirements, single-stage single-suction vertical centrifugal pumps will be more widely used and developed.
