Pump station without accumulator: description, device and reviews

Technologies in the field of pumping equipment forToday allow a private homeowner to fully assume the tasks of providing water. Models of pumping stations with compact dimensions cover the requirements for watering, and powerful units with increased capacity realize the rise of water to the second floor. To maintain a stable pressure in the circuits, the developers are increasingly using a hydraulic accumulator. This solution has many obvious advantages, but not always such power additions are appropriate from the point of view of operational rationality. In turn, a properly selected pump station without a hydraulic accumulator can provide the target facility with water with minimal financial and technological costs.

General information about pumping stations

The principle of operation of water pumping stations inmuch the same as conventional pumps. The difference lies in the use of automatic means of monitoring the process and the possibilities of additional equipment - primarily due to the same hydraulic accumulator. But even models without a hydraulic tank outperform conventional pumps in terms of capacity. For example, on average, 2-5 m3 / h is required to supply a private house. In this range, there is a pumping station for a private house without a hydraulic accumulator, put into a well or into a well. A significant difference is the strong element base, enclosed in a stainless steel casing. It is the models without a hydraulic accumulator in this sense are given more attention, since they work at high loads without additional insurance from a hydrotest.

How is the pump station built without a hydraulic accumulator?

The design of the station is formed by a whole complexfunctional elements. All models without exception are supplied with a pump, which ensures pumping of water from the source. The unit functions are controlled via a relay. At least through it, the user can regulate sufficient head pressure. A pressure gauge is used to control the pressure, which is usually included in the basic configuration. Also, without fail, a pumping station without a hydraulic accumulator includes an electrical cable, grounding terminals and a connector for connection to the network. Not always the above components are supplied complete. If you want, you can compose the station from different components - the main thing is that they match each other according to the characteristics.

Assembling the station

The assembly process takes place at a future locationoperation, when a water supply line from a well or well source is already organized. Complete pumps for input and output are connected to the pump. Next, they connect hoses - respectively, from the source of the fence and from the water supply to the place of use. The recoil line may be somewhat depending on the design of the station. It is possible to properly assemble the pump station manually without a hydraulic accumulator for several consumers, taking into account the load on the electric grid. As the waste channels increase, productivity will also increase. Therefore, it is recommended to ground using a residual current device. Such devices are usually present in the kit, as well as control accessories with sensors, measuring devices and automata. The latter are introduced into the infrastructure of the plant at the final stage of installation.

Nuances of operation

The assembled unit should be located inon a stable, level surface. Both lines of connection (to the source of water intake and electricity supply) must be isolated and protected from external influences. During the pumping process, the pump will not cycle for water supply, as in the case of a hydraulic accumulator. The fence will occur directly to the point of consumption, which increases the responsibility of monitoring equipment. At the same time, the operation of a pumping station without a hydraulic accumulator presupposes automatic shutdown and start-up. Threshold values ​​can be set via the control relay, but in this case it is important to correctly evaluate the loads to the station without counting on the support of the buffer block.

Positive feedback about stations without a hydraulic accumulator

Most users point toergonomic design, which is simplified in comparison with pumps, supplemented by a hydroaccumulator. These are small and lightweight units, which do not cause any special problems in installation and operation. There is also the possibility of convenient placement of such models in pits with the presence of a wireframe base. But this aspect will depend on the form factor in which the pump station is installed without a hydraulic accumulator. Feedback on borehole modifications, for example, underscores the variety of mounting options in the vertical and horizontal planes. Stations with a hydroaccumulator do not provide such possibilities - as a rule, only a single horizontal arrangement is allowed.

Negative feedback on stations without a hydraulic accumulator

Weak places for models of this type are also many. In practice, the owners of equipment note modest performance. And use of the maximum resource to fill the lack of capacity is not allowed. Here we are talking about a shortcoming in the form of a risk of a hydrostatic attack. These are less protected structures, therefore it is desirable to set the average operating parameters during operation. In general, a pumping station without a hydraulic accumulator is perceived in the market as an obsolete solution. In part, this is due to performance limitations, but there is also a process of reducing the optional content, as manufacturers are losing interest in the segment.

Conclusion

Inclusion in the design of pumpsThe accumulator certainly raised the possibility of organizing private water supply to a new level. This applies to improving the reliability of equipment, and increasing its power performance. Nevertheless, there are tasks with which it is better to cope with pumping stations without a hydraulic accumulator. The price of such units, which averages 7-15 thousand rubles a year, is also an important factor in favor of this choice. For example, for 10 thousand you can buy a high-quality installation, the capacity of which is enough for watering the garden and covering household needs at the dacha. The accumulator for such a system will not be of much use, but it will necessarily become another power consumption item. Depending on the needs, conventional stations can also serve a private house, but in this case it will be necessary to refer to the most productive models in the segment.
