The rules of how to choose a pumping station to give are important for anyone who wants to ensure their life with autonomous and uninterrupted water supply at any time of the year. This simple device allows you to automatically supply water to any point of water consumption. The installation is able to provide sufficient pressure in the water supply system under any conditions, even when the pump is off. The main thing is to make a competent choice of equipment and correctly mount it on your own summer cottage.
Overview of available types of pumping stations
Whatever the pumping station, it includes: a pump, a hydraulic accumulator, a pressure gauge, a pressure switch, various valves and filters. Manufacturers can somehow complete the installation with different types of the listed devices, what determines its performance and appearance. Therefore, the question of how to choose a pumping station to give the most optimal, always remains relevant.
Pumping stations, which are popularly called “turrets”, can vary in the following parameters:
- the type and appearance of the pump installed on the device;
- key technical parameters;
- the material used to create the hydroaccumulator capacity and its volume;
- height of raising the column of water from the source;
- the possession of various additional options, which most often include various devices to protect against “dry running” or overheating;
- cost of the whole set.
There are two types of pumps that are equipped with “turretless”. Most often, these are surface air-cooled centrifugal pumps, which almost all manufacturers install directly on the hydroaccumulator. The second type of stations is equipped with submersible pump types. They are lowered straight into the well or well.
Stations equipped with surface types of pumps are: multi-stage, self-priming with a remote or built-in ejector, centrifugal.
Centrifugal pumps can provide a not too great suction depth. Most often it is 7 – 8 m. They have a high enough pressure, but low productivity. To run such a pump, you must first fill the entire line with water. They make a lot of noise, so their installation is shown at a sufficient distance from the housing.
How to install a pump to increase the water pressure in the apartment. The classification of pumps to increase the pressure in the water supply of the apartment. Selection criteria, especially self-installation.
Water supply stations equipped with multi-stage types of pumps have the same suction depth and require mandatory filling of the suction line, but they are favorably distinguished by a more acceptable noise level in the operating state, higher water rise and high efficiency. This option is much better suited for installation indoors cottages due to the permissible noise level.
Self-priming pumps with an integrated ejector provide the station with much greater depth (up to 9 m) from which it can lift water. The pressure at such stations is average with good performance. But its main advantage is the possibility of normal start even with a lack of water in the pipeline. If the pump is equipped with a remote ejector, the suction depth can reach a record 45 m.
Helpful advice! Pumps with a remote ejector have a complex structure and “sin with whims” during operation. In addition, they are difficult to mount. Therefore, if you decide how to choose a pumping station for the dacha, then this choice should be made only with deep groundwater in the event of the impossibility of using a submersible pump.
Some pumping stations are equipped with deep-well (submersible) pumps. They are either centrifugal or vibratory. Such pumping stations should be selected in relation to the type of water supply source on the site. The diameter of the well or the depth of the well directly affect this choice. The more powerful the pump, the higher it can lift water. At the same time it is necessary to take into account the amount of water in the source.
It may happen that a too powerful pump drains the source too quickly. Vibration pumps (“Kid”, “Streamlet”, etc.) are cheaper and simpler, both during operation and during installation. However, they are less powerful than centrifugal. If the depth of groundwater over 9 m, then choose a pump station to give, as a rule, it is possible only with a submersible pump.
Before making a decision on choosing a pumping station, you need to know which device specifications you should pay attention to when buying. The most crucial of these are power, pressure and performance. To give enough station with a capacity of 0.6 to 1.5 kW. The dependence of performance and pressure on each other can be depicted graphically, which is what the manufacturers do by placing such graphics in the device passport. Productivity is usually measured in m? / H, while the pressure in meters of a water column or atmospheres (for reference, 1 atm = 9.8 m water line).
Many stations are equipped with protective devices that look like sensors that can shut off the device when overheated, or the so-called “dry run”, when there is no water in the system. This makes the cost of the station higher, but also assumes its safer use. The kit usually has a check valve and a water filter. In their absence, the purchase and installation of these elements is required.
Before choosing a unit, a specific analysis of the current conditions should be carried out. In particular, it is necessary to find out: what type of source for water supply will be used – a well or a well, their depth and the volume of available water reserves, the maximum possible water flow and the need for it.
Now you can safely proceed to the choice of the desired device according to the following standards:
- level to 8 m – the station with the superficial pump will approach. This indicator is more – there is no alternative to the submersible pump;
- according to the technical characteristics, we select equipment that will meet all the requirements for the height of water rise, its maximum flow rate and sufficiency of pressure in the system. To this you need to add on from 10 to 20% of the power for hydraulic losses in filters and various valves;
- selection of the hydroaccumulator according to its volume is carried out on the basis of how much water you need in the absence of electricity. For a family, an acceptable option is to purchase a device with a capacity of 50 liters, and 24 liters is enough for one person. The pump resource also depends on the size of the tank, since it will be switched on less frequently the more it is.
Helpful advice! When choosing the volume of the accumulator, you need to make sure that it enters the prepared place. If not, then you need to either change the place of installation, or be content with a smaller volume of the accumulator.
For self-installation of the pumping station at the cottage it is necessary to determine the most optimal place. You will have to choose from three options: in the immediate vicinity of the well or well, in one of the utility rooms, in the house itself.
If the installation is carried out near the source of water consumption, then it is necessary to arrange a special insulated chamber, which is called a caisson. From it lay a pipe to the house on 25 or 32 mm in a trench which is warmed.
Helpful advice! So that the insulation of the supply pipe is efficient and reliable, it can be wound with a heating electric cable. It is necessary to deepen the pipe below the level of soil freezing. Special attention to warming must be given at the entrance of the pipe to the foundation of the house.
To avoid the construction of additional heat-insulated facilities, it is advisable to install a pumping station directly in the house. A basement or any utility room is well suited for this. In this case, you need to choose a device with a small noise level. Installation in a separate utility room is possible only with its proper insulation.
In the absence of a centralized water supply, everyone understands how important the pumping station is to give. How to choose the most appropriate device, we discussed in this article. Therefore, no one should have great difficulty in installing it.
