Installing the pump is not the easiest process, so most people prefer to entrust this work to specialists. However, in the presence of competent instructions, pumping station can be installed independently.
First of all, we will understand the main components of the pumping station:
– the pump itself;
– a tank or hydraulic accumulator (that is, storage tanks);
– control panel, switches (station control system);
– some additional devices that it offers the best tool shop, and which make operation of the pumping station easier (this is, for example, a filter, a non-return valve, a pressure gauge, etc.).
Now we will consider the question of choosing a place to install the station. Usually, this need arises immediately after the completion of the well drilling process and the purchase of the necessary equipment. Below are listed important criteria that must be taken into account when choosing a place to install a pumping station:
1) Distance from the station to the well (well). It should be minimal, but at the same time, the station should be located at the greatest distance from the highest groundwater level
2) The equipment should not be installed in an open place or in some room intended for other purposes. The most optimal option is to build a separate special room in which the temperature will be approximately the same around the clock. Moreover, it should be available in any weather, in case the station needs to be repaired.
3) Due to the fact that the station works on electricity, the selected place must be ventilated and well protected from moisture.
4) The pumping station must be firmly fixed on the surface.
So, based on the above criteria, it is possible to list possible places suitable for installing the station. This is an isolated room inside the house or basement (installation not in a separate room leads to the risk of accidental damage). Also, it can be a specially prepared surface in the well (it must be taken into account that in this case you will have to think about the use of insulation and the correct calculation of the distance to the water), a separate booth made of wood or stone (you will also need to think about creating special conditions, including insulation ), caisson (site at the outlet of the well).
After you have decided on the place, the problem of connecting the pump to the well arises. First of all, it is necessary to lay the pipeline from the station to the well. This must be done so that the pipe is below the level of soil freezing, but above the level of groundwater. Moreover, it is necessary to think about the method of thermal insulation of the pipe. As for the choice of material, experts prefer pipes made of plastic or polyethylene to metal.
Then it is necessary to connect the coarse filter and fix the non-return valve with the help of a coupling. Before turning the valve, the thread must be filled with some sealing substance. The choice between an ejector, a two-pipe station or a single-pipe depends on the level of groundwater. The ejector will be required only if it is higher than 10 m.
Pipes are connected to the ejector with couplings and sealed with mounting foam. After the ejector is lowered to the required depth, it is necessary to make sure that the top of the casing pipe coincides with the corresponding mark on the pipe. Then it is necessary to fix the head of the knee.
Finally, the final stage is the connection of the pumping station itself. The direct tap must be connected to the station itself, and the plastic pipe must be attached to the coupling using a collet connection.
Before starting the station, it is necessary to check the strength of all connections, as well as the pressure in the accumulator. In order to test the station before starting, you can pour a little liquid into the hole on top of the pump.
