Centrifugal surface pump for a well, for a well, for dirty water

Pumps and similar means involved in pumping various liquids can be conditionally divided into two categories. The first will include units designed to maintain clean water, and the second - models designed for contaminated environments. This does not mean that the second option is initially oriented only on the poor quality of the carrier, but in working with water bodies and rivers, for example, there is no other way out. In solving such problems, a centrifugal surface pump is used for dirty water, which is resistant to blockages. It is usually used for watering activities and, incidentally, not only in dealing with contaminated sources.

Features of the design and principle of operation

Such units have a horizontal positioning of the structure, since they are used as a surface device and are fixed on the surface of the earth. In this position, the centrifugal surface pump is more stable, despite the active operation of the inner wheel. Actually, due to the rotation of the blades of this element, a centrifugal force is realized. Here, and served carrier, and then discarded on the walls and sent to the channel of tap. As a result, water passes several stages of circulation - first it flows through the hose to the main chamber of the pump, then it is processed by blades and sent along the outgoing channel to the irrigation system or to another consumer.

The entry level versions provide for a single impeller in the design. Such models are usually used for irrigation of suburban areas. However, a centrifugal surface pump for a well that participates in a water supply system at home has a more complex device and several internal wheels.

Main characteristics

Take into account the lifting height, capacity, and in some cases the dimensions of the pump with the housing material. As for the first parameter, the standard versions are capable of lifting up to 20-30 m. In models designed for wells, this value can reach 70 m. The productivity is most often interrelated with the height of the lift and varies on average from 20 to 150 l / min . The dimensions of the installation usually correspond to the features of the application. The traditional centrifugal surface pump is quite impressive, but if we are talking about modifications designed to work in a well, the dimensions can be significantly reduced. A similar situation with materials of manufacture. Under normal conditions, plastic models can be used on the surface, but for harsh conditions it is recommended to purchase cast iron units and modifications with stainless steel casings.

Models for wells

The design of centrifugal aggregates provides for the possibility of creating devices that can be used for a well. For example, in the models of household models often there are units with a small power of about 550 W, capable of supplying water from sources remote in depth. In the organization of complex multi-stage irrigation systems, an auxiliary centrifugal surface pump can also be used, which will allow the function of stabilizing the pressure and distribution of water. Use of such units is possible and for professional purposes. For example, for the devastation of contaminated sites in enterprises, the pumping of working fluids, etc.

Versions for wells

Water from the wells can be pumped not only for the purpose of further irrigation, but also for the maintenance of household needs in the house. In this case, a large volume of water supply and a unit corresponding to power are required. Optimal option will be a surface centrifugal pump for a well in the form of an autonomous station. Such devices are equipped with a capacious tank, which can act as a backup water storage.

Before purchasing such a model, you should evaluate its ability to pump. In standard versions, pumping stations of this type allow an 8-meter elevation. To control the performance, the user can use a special relay, supplemented by pressure sensors. This example shows that a centrifugal surface pump for dirty water can be used for other purposes, while maintaining the optimum quality of the liquid composition.

Installing the pump

The pump is installed on the surface, after which it is securely fixed. It is important to ensure conditions that will not allow the unit to deviate from the specified position. Next, the incoming trunk is installed. On the one side of the hose, it is necessary to attach a non-return valve, and on the other - to connect it to the pump's communications. During the connection operations, a sealing flax or a ribbon tape should be used, which will add reliability to the transitional sections and prevent the risk of leaks. Questions about how to install a surface centrifugal pump in the well, usually provide for and consideration of filling factors of the highway. After the check valve is immersed in the well, it is possible to start the unit. First of all, the main line should be filled, and then the reserve tank mentioned above. When the optimum values are reached, the pump will automatically shut off.

Operation and Maintenance

The work process assumes minimal human involvement, if the pump design has automatic control systems. In the latest versions, manufacturers supply units with control panels, which allow you to control the equipment from a distance. Since the breakdown of surface centrifugal pumps is not uncommon, the risk of their occurrence should be minimized as much as possible. Depreciation of functional components, impairment of the function of the centrifugal wheel and unsatisfactory tightness - these and other problems can be prevented if the unit is cleaned in a timely manner and only connected to compatible elements.

Conclusion

In terms of functionality and variety of applications, this type of aggregates has no equal. Even in a simple configuration, a centrifugal surface pump can pump water from rivers, ponds, wells and garden tanks. Another direction of operation of structures of this type is drainage. Having provided the pump with a float mechanism, the user can leave the equipment working without constant supervision. As the water is pumped to a certain level, the system will automatically stop its function without the risk of getting damaged due to idling.
