The applications for the vertical turbine pumps

Views:2     Author:Site Editor     Publish Time: 2019-07-08      Origin:Site

Vertical turbine pumps are primarily used wherever submersible pumps are not available, as the flow is higher than the turbine's range, or because the owner prefers a conventional motor mounted on top of the pump.

What is a vertical turbine pump?

vertical turbine pumps are specially designed centrifugal pumps used to move water from wells or reservoirs deep underground. Also known as a deep well turbo pump or a bobbin turbo pump, it is one of two main types of turbo pumps. The two main types of turbo pumps are vertical turbine pumps and submersible turbo pumps. Although the submersible pump's motor is located underwater at the bottom of the pump, the vertical turbine pump's motor is above the ground and is connected to the impeller at the bottom of the pump through a long vertical shaft. The term "turbine" in the name of the pump is a bit of a misnomer because the type of pump is independent of the turbine.

 

What are the main applications of vertical turbine pumps?

The vertical turbine pump is a water-lifting machine that works directly between the motor and the water pump. It is suitable for extracting groundwater from deep wells. It can also be used for water extraction projects such as rivers, reservoirs, and canals. It is mainly used for irrigation of farmland and water for humans and animals in plateau mountains. It can also be used for water supply and drainage in cities, factories, railways, mines and construction sites. Since the vertical turbine pump is directly driven into the water by the motor and the pump body, whether it is safe and reliable will directly affect the use of the deep well pump and the working efficiency. Therefore, the vertical turbine pump with high safety and reliability is also the first choice.

In a groundwater source heat pump air conditioning system, the water supply to a vertical turbine pump is often sufficient to meet the water requirements of two or more heat pump units. However, in actual operation, it was found that the heat pump unit was operated at part load most of the time, while the vertical turbine pump was always operating at full load, resulting in a large increase in electricity and water charges.

The frequency conversion speed regulation technology has many applications of water pump and fan in the air conditioning system with its remarkable energy saving effect and reliable control mode, and its technology is also relatively mature, but the vertical turbine pump water supply application in the groundwater source heat pump air conditioning system is still very Rare, but it is quite necessary. A pilot survey of groundwater source heat pump applications in Shenyang found that in a groundwater source heat pump air conditioning system, when the heat pump capacity is not large, the water supply of a vertical turbine pump can meet the water required by two or more heat pump units. In actual operation, it was found that the heat pump unit was partially loaded for most of the time, while the vertical turbine pump was always operating at full load, resulting in a large increase in electricity and water charges. Therefore, the application of vertical turbine pump variable frequency speed regulation water supply technology in groundwater source heat pump system has great energy saving potential.

The vertical turbine pump uses a temperature difference control method. Since the heat pump unit must ensure that the evaporator water temperature cannot be too low under the heating condition, a temperature sensor is set on the return pipe of the vertical turbine pump, and the set temperature is tjh. When the return water temperature of the well water source side is greater than the tjh value, the vertical turbine pump controller sends a lowering current frequency signal to the frequency converter, the frequency converter reduces the frequency of the input power source, the number of revolutions of the vertical turbine pump is correspondingly reduced, the water supply amount of the pump, the shaft Power and motor input power are also reduced, thus achieving energy savings. When the water source side return water temperature is lower than the tjh value, the frequency increase adjustment




vertical turbine pumps are commonly used for drilling to provide agricultural or lawn irrigation, or to provide water supply to municipalities that rely on groundwater rather than surface water. They are also used to supply plant water and fire water to factories .


For deep well pump, Submersible Deep Well Pump is also applicable
