The working principle and characteristics of pipeline centrifugal pump

Classification:

Because the pipeline centrifugal pump has good pressurization capacity and remote water delivery capacity, the pump has a wide range of application scenarios. It can be seen everywhere in our daily life. For example, pipeline centrifugal pumps are often used in residential and high-rise buildings to transport a variety of domestic water. But many users are very interested in the working principle of the pipeline centrifugal pump, so let's understand the working principle and characteristics of the pipeline centrifugal pump together!

The working principle of the pipeline centrifugal pump is actually not complicated. The pump is mainly used to transport water under the action of centrifugal force. The pipeline centrifugal pump usually adds a large amount of water to the pump body and the water supply pipe before starting to use to maintain a vacuum state. After the pump starts to work, the impeller rotates rapidly, the water accelerates under the action of this force, and the rotating water splashes out from the impeller under the action of centrifugal force. When the water in the pump is thrown out, the center of the impeller becomes a vacuum area, and the water from the water source connected to it is squeezed out into the pipeline through air pressure or water pressure.

Pipeline centrifugal pump can send water is the role of centrifugal force. Before the pump is started, the pump body and water supply pipe must be filled with water in a vacuum state. When the impeller rotates quickly, the impeller makes the water rotate quickly, and the rotating water splashes from the impeller under the action of centrifugal force. After the water in the pump is thrown out, the central part of the impeller becomes a vacuum area. Suwon water is atmospheric pressure (or water pressure) through the pipe network pressure into the inlet pipe. Through this cycle, continuous pumping can be performed. It is worth noting here that the centrifugal pump must be filled with water before starting the pump casing. Otherwise, it will cause the pump body heat, vibration, water reduction, damage to the pump (referred to as "cavitation"), resulting in equipment accidents.

　Pipeline centrifugal pump features:

1. The impeller is directly installed on the motor extension shaft, with short axial size, compact structure, reasonable configuration of pump and motor bearings, which can effectively balance the radial and axial loads caused by pump operation, stable pump operation, low vibration and noise

2. The shaft seal adopts mechanical seal or mechanical seal combination, imported titanium alloy sealing ring, medium-sized high temperature resistant mechanical seal and hard alloy material, and adopts wear-resistant seal, which can effectively extend the life of mechanical seal.

3. The installation and inspection are convenient, and all rotor parts can be pulled out by removing the nut of the pump joint without removing the piping system.

4, according to the use of the requirements of flow and head needs, can be used in series, parallel operation mode of pump.

5. The pump can be installed vertically and horizontally according to the pipeline layout requirements.

　　pipeline centrifugal pumpThe application solves the transportation problem to a large extent, and is widely used in industrial and urban water supply and drainage, high-rise building pressurized water delivery, garden sprinkler irrigation, fire pressurization, long-distance transportation, heating and refrigeration cycle, bathroom and other cold and hot water circulation pressurization and equipment matching.

How to store, transport and anti-corrosion measures for high-lift deep well pumps For well pumps containing packed wooden boxes, they should be placed on a flat concrete floor. For deep well pumps without packed wooden boxes, they should be discharged flat on the pump rack with 3 support points. Both sides shall not be suspended in the air for more than 1m.
