Technologies in the field of pumping equipment today allow a private homeowner to completely take on the task of providing water. Models of pumping stations with compact dimensions cover the needs for irrigation, and powerful units with increased productivity realize the rise of water to the second floor. To maintain a stable pressure in the circuits, developers are increasingly using a hydraulic accumulator. This solution has many obvious advantages, but such power additions are not always appropriate from the point of view of operational rationality. In turn, a correctly selected pump station without a hydraulic accumulator can provide the target with water with minimal financial and technological costs.
General information about pumping stations
The principle of operation of water pumping stations is in many ways similar to conventional pumps. The difference lies in the use of automatic means of process control and the possibility of additional equipment - primarily due to the same accumulator. But even models without a hydraulic tank outperform conventional pumps in terms of power. 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, introduced into a well or a well. A significant difference is the strong elemental base, enclosed in a stainless steel case. Models without a hydraulic accumulator in this sense are given more attention, since they work at high loads without additional insurance against hydraulic shock.
How is a pumping station without a hydraulic accumulator arranged?
The design of the station is formed by a whole complex of functional elements. Without exception, all models are equipped with a pump, which ensures the pumping of water from the source. Unit functions are controlled by relays. At least through it, the user can adjust the sufficient pressure. To control the pressure, a pressure gauge is used, which is usually included in the basic package. Also, without fail, the pumping station without a hydraulic accumulator includes an electric cable, grounding terminals and a socket for connecting to the network. The above components are not always delivered complete. If you wish, you can build a station from different components - the main thing is that they correspond to each other in terms of characteristics.
Station assembly
The assembly process is carried out at the future site of operation, when a water supply line from a source — a well or a well — has already been organized. Complete nozzles for input and output are connected to the pump. Then hoses are connected to them - respectively, from the source of the intake and from the water supply circuit to the place of use. The return lines may be several depending on the design of the station. Properly assemble a pump station with your own hands without a hydraulic accumulator for several consumers is possible only taking into account the load on the power grid. As waste channels increase, productivity will increase. Therefore, it is recommended to ground with a residual current device. Such devices are usually present in the kit, as well as control fittings with sensors, measuring instruments and automatic devices. The latter are introduced into the infrastructure of the station at the final stage of installation.
Operation Nuances
It is advisable to place the assembled unit in the hozblok on a stable flat surface. Both connection lines (to the source of water intake and the power supply network) must be isolated and protected from external influences. During pumping, the pump will not cycle for a supply of water, as is the case with a hydraulic accumulator. The fence will take place directly to the point of consumption, which increases the responsibility of the control equipment. At the same time, the operation of a pumping station without a hydraulic accumulator involves automatic shutdowns and turns on. Threshold values can be set via the control relay, but in this case it is important to correctly assess the load on the station, not counting on the support of the buffer unit.
Positive feedback on stations without accumulator
Basically, users indicate an ergonomic design that is simplified compared to pumps supplemented with a hydraulic accumulator. These are small and lightweight units that do not cause any special problems in installation and operation. The possibility of convenient placement of such models in pits with a frame base is noted. But this aspect will depend on in what form factor the pump station is made without a hydraulic accumulator. Reviews of downhole modifications, for example, emphasize the variety of mounting options in the vertical and horizontal planes. Stations with a hydraulic accumulator do not provide such opportunities - as a rule, only a single horizontal placement is allowed.
Negative reviews about stations without accumulator
There are also many weaknesses in this type of model. In practice, equipment owners have noted modest performance. Moreover, the use of the maximum resource to fill the lack of power is not allowed. Here we are talking about a drawback in the form of the risk of water hammer. These are less protected structures, therefore, in the process, it is desirable to establish average operating parameters. On the whole, a pumping station without a hydraulic accumulator is perceived on the market as an aging solution. This is partly due to performance limitations, but there is also a process of reducing optional content, as manufacturers lose interest in the segment.
Conclusion
The inclusion of a hydraulic accumulator in the design of pumps undoubtedly raised the possibility of organizing private water supply to a new level. This also applies to increasing the reliability of equipment, and increasing its power indicators. Nevertheless, there are tasks that pump stations without a hydraulic accumulator are better able to cope with. The price of such units, which averages 7-15 thousand rubles, also acts as an important factor in favor of this choice. For example, for 10 thousand, you can buy a high-quality installation, the capabilities of which are enough to water the garden and cover household needs in the country. A hydraulic accumulator for such a system will not bring much benefit, but it will certainly become another item of energy consumption. Depending on the needs, ordinary stations can serve a private house, but in this case you will have to turn to the most productive models in the segment.
