Horizontal multi-stage rustproof cast iron circulating pump is a highly efficient and durable pumping equipment widely used in various heating, water supply and industrial circulating systems.
1.Structural features
Horizontal design: the pump adopts horizontal installation, compact structure, small footprint, easy to install and maintain.
Multi-stage impeller: The pump body is equipped with multi-stage impeller, which can increase the pressure energy of the liquid step by step, so as to obtain higher head and flow.
Rust-proof cast iron material: the pump body is made of rust-proof cast iron, which has good corrosion and abrasion resistance, and is suitable for conveying clear water and substances with physical and chemical properties similar to those of clear water.
Shaft sealing structure: Usually adopts packing or mechanical sealing, which is safe and reliable and can effectively prevent liquid leakage.
2.Working Principle
The working principle of horizontal multi-stage rustproof cast iron circulating pump is similar to that of ground centrifugal pump. When the motor drives the impeller on the shaft to rotate at high speed, the liquid filled in the impeller, under the action of centrifugal force, is thrown from the center of the impeller along the flow channel between the blades to the surrounding of the impeller. As the liquid is acted by the blades, the pressure and speed increase at the same time. After passing through the flow channel of the guide shell, the liquid is led to the next level of the impeller, and flows through all the impellers and guide shells one by one, further increasing the pressure energy of the liquid. Finally, the liquid is transported to the required position.
3.Performance Parameters
The performance parameters of horizontal multi-stage rustproof cast iron circulating pump include flow rate, head, power, rotational speed and so on. Specific parameters vary depending on the pump type, specifications and application scenarios. When selecting the pump, the appropriate model and specifications should be selected according to the actual needs of the system.
4.Application Scenario
Horizontal multi-stage rustproof cast iron circulating pumps are widely used in various heating, water supply and industrial circulating systems. For example, in the heating system, the pump can be used to circulate hot water to ensure the stability of indoor temperature; in the water supply system, it can be used to pressurize water supply and improve water pressure and flow; in the industrial circulation system, it can be used to convey various corrosive or abrasive media.
