Vertical centrifugal pumps for conveying water and other liquids with similar physical properties of the water, suitable for industrial and urban water supply and drainage, high-rise building pressurized water, garden spray fire booster, long-distance water, heating, bathrooms and other warm and cold pressurized water cycle and equipment and other.

Centrifugal flow components centrifugal flow components are: the suction chamber, impeller, press out the three parts room. The impeller chamber is a pump core, the core component is the flow. Pump through the impeller for liquids for power, making energy increases. Direction of the liquid flowing out of the impeller into three categories: (1) the radial flow impeller (centrifugal impeller) with the fluid along a direction perpendicular to the axis out of the impeller. (2) mixed flow impeller (mixed flow impeller) the liquid is flowing along the axis of the tilt in the direction of the impeller. (3) the direction of the axial-flow impeller with a liquid flow parallel to the axis. Impeller by inhalation divided into two categories: (1) single-suction impeller (ie, from the side of the impeller suction liquid). (2) double suction impeller (ie, from both sides of the impeller suction liquid). The impeller cover forms into three categories: (1) Closed impeller. (2) an open-type impeller. (3) semi-open impeller. Closed impeller which application is very broad, single-suction impeller aforementioned double suction impeller belong to this form.

The working principle of centrifugal pump
Centrifugal pump works: Centrifugal pumps so water can send out is due to the effect of centrifugal force. Before working pump, pump and into the water tank full of water must form a vacuum state, when the rapid rotation of the impeller blades rotate quickly prompted water, water flew from rotating impeller centrifugal force, the water within the pump after being thrown out, the central portion of the impeller to form a vacuum region. Suwon water at atmospheric pressure (or pressure) in the role of the inlet pressure to the inside through the pipe network. Such endless loop, you can achieve continuous pumping. It is worth mentioning: it has to start before the centrifugal pump housing later filled with water before starting, otherwise it will cause the pump heat, vibration, reducing the amount of water, causing damage to the pump (referred to as "cavitation") resulting in equipment accident! Many different types of centrifugal pumps, classification There are several common ways a press Impeller points: single-suction centrifugal double suction centrifugal pump. 2 Press the number of impeller points: single-stage centrifugal pump multi-stage centrifugal pump. 3 Press the impeller structure: open impeller centrifugal pump semi-open impeller centrifugal Closed impeller centrifugal pump. 4 Press the working pressure points: low-pressure centrifugal pump high-pressure centrifugal pump centrifugal pump side vertical centrifugal pump.

Here are a few important centrifugal pump performance curve.
Pump performance parameters such as flow rate Q Head H shaft power N speed n efficiency η certain relationship exists between. The magnitude of change in the relationship between them is represented by a curve. This curve is called the performance curve of the pump. Changes in the performance of the mutual relationship between the parameters of the pump and mutual restraint: the first in the frontoparietal speed pump is a prerequisite. There are three main pump performance curve curves: flow - lift curve, flow - the power curve, flow - efficiency curve.

A, flow - lift characteristic curve
It is the basic centrifugal pump performance curve. Specific speed centrifugal pump having less than 80 rising and falling characteristics (both intermediate projections, both sides recurved), said the hump performance curve. Specific speed between 80 to 150 centrifugal pump has a flat performance curve. Than the number of revolutions of the performance curve has a steep drop in more than 150 centrifugal pump. Generally speaking, when traffic hours, lift it high, lift traffic increases gradually decline.

B, flow - power curve
Shaft power increases with the flow rate when the flow rate Q = 0, the corresponding shaft power is not equal to zero, and a constant value (about 60% of the normal operation). This power is mainly consumed in the mechanical loss. At this point there is full of water pumps, if the long run, will lead to rising temperature inside the pump, pump casing, the bearing may have a fever, severe heat may cause deformation of the pump, we called a "stuffy head" at this time head for the maximum, when the valve is gradually opened, traffic will gradually increase, shaft power has slowly increased.

C, flow - efficiency curve
Elephant head shape which curves, when the flow rate is zero, efficiency is equal to zero, as the flow increases, the efficiency is gradually increased, but to a certain value after the decrease of the efficiency, a maximum efficiency value, the maximum efficiency near the point, the efficiency is higher, this area is known as high-efficiency area. Fifth, the pipeline centrifugal classification pipeline centrifugal main products are pipeline centrifugal pump, vertical heat pumps, vertical temperature centrifugal pumps, vertical pipeline chemical pumps, vertical pipeline pumps, vertical stainless steel explosion-proof chemical centrifugal pump. Sixth, the pipeline centrifugal pump applications 1. Pipeline centrifugal pump for conveying water and physical and chemical properties similar to water or other liquids for industrial and urban water supply and drainage, high-rise building pressurized water, garden irrigation, fire booster, long-distance transport, HVAC refrigeration cycle, bathroom, heating and water circulation and equipment for pressurized, temperature T <80 ℃. 2. The vertical heat pumps for metallurgy, chemical industry, textile, wood processing, paper and restaurants, bathrooms, hotels and other high-temperature hot water boiler loop pressurized transport and urban housing heating circulating pumps, temperature below 120 ℃. 3. Vertical centrifugal pumps are widely used in high temperature: energy, metallurgy, chemical industry, textile, paper and restaurants, bathrooms, hotels and other high-temperature hot water boiler loop pressurized transport and urban housing heating circulating pumps with pipes, temperature below 240 ℃. 4. The vertical pipeline chemical pump for conveying solid particles, corrosive, liquid viscosity similar to water, suitable for petroleum, chemical, metallurgy, electricity, paper, food and pharmaceutical and synthetic fibers and other departments, the use of temperature is - 20 ℃ ~ 120 ℃.

Five, pump installation considerations
(1) of the base surface of the installation must be smooth, clean and can withstand the corresponding load; (2) the need to use a fixed place anchor bolts; (3) for vertical mounting of the pump must have sufficient strength bolt ; (4) If the vertical mounting, the motor must be located above the water pump; (5) when fixed to the wall, pay attention to alignment, alignment.
