Often the greatest problems with water supply are experienced by residents of private homes. But all this was decided earlier with the help of arrangement of wells. True, they had to carry water in buckets, which takes a lot of time and is a laborious task. Today, a pumping station can do water delivery. An appropriate well is needed for the pumping station, and the installation must be completed correctly. We will talk about all this in this article.
A bit of general information
The pumping station consists of an electric pump , a check valve and a hydraulic accumulator. Water tanks should also be available. For example, if possible, you can put several plastic tanks in the basement or underground room. This will allow you to always have a stock in case of unforeseen situations. However, you will need a well for the pumping station. This may be a well of small depth. In addition, you will install a coarse and fine filter. In general, the pumping station will operate without electricity, which is its main advantage, but we will talk about this a little later. Choosing a pumping station is a pretty crucial step. Usually it is necessary to be guided by the company, the performance of the equipment and its quality in general.
Pump station design
Any, even the simplest and cheapest pumping station is equipped with a check valve. It is necessary to protect against dry suction. This increases the safety and durability of using the electric pump. Another important detail is the coarse filter. It serves to protect the check valve and pump from mechanical impurities. But the most important and interesting detail is the reservoir. As standard, it is manufactured in two parts. In one of them is water, and in the second is air under pressure. This allows you to use water even without electricity. Air presses on the water that flows through the pipes. Usually the pressure is sufficient to ensure normal pressure. The non-return valve in this case prevents the carrier from flowing into the pump. But the accumulator is not a storage tank. The volume of the latter can be quite large, at the same time the expansion tank usually has a supply of not more than 50 liters of water.
The principle of operation of the pumping station
The well for the pumping station is used as the main source of water. Using a pump, the carrier is pumped into the expansion tank. After that, the station goes into standby mode and remains in it until the pressure in the accumulator reaches a normal value. When the consumer opens the faucet, the water flows under pressure through pipes. Gradually, the pressure in the tank begins to drop, and when it reaches a certain point, the pump turns on again and the fluid is pumped. During intensive operation, the pump heats up. The cooling system is simple enough and consists in the flow of cold water through the station. If overheating nevertheless happened, the automatics shuts down the pump. Well, now let's talk about how the installation is performed.
Connecting the pumping station to the well
The first problem faced by residents of a private house is the issue of installing a pumping station. The process itself cannot be called complex and time-consuming. The most important thing is to choose the right installation location. In general, the closer the station is to the well, the better. Typically, the suction depth of the pump is limited to 10 meters. Moreover, the farther the station, the worse the set becomes, due to friction losses. So, for every 10 meters of the pipe, 1.2 meters of pressure go. But in this case, a submersible pump station for a well is more appropriate. Using a submersible pump allows you to use a very deep well or well. In the well you can always organize a special platform on which the station is installed. So it will not freeze in the winter.
Installation of a pumping station in a well
The station legs have special holes for anchors. With their help, it is necessary to fix the pump on the surface of the well or inside on a special site. The last option is good because the water will not freeze. The first makes it easier to maintain equipment. There are only two exits at the station. One of them is connected to the well, for which a regular plastic pipe is used. It sinks into the water with a small margin and is connected to the pump. In this case, do not forget to install the coupling and check valve on one side of the pipe. Thanks to this, the pipe will always be filled with water, which is the main protection against dry absorption. Lastly, a coarse filter is installed. The end of the pipe with the coupling, valve and filter falls under the bottom of the well. Such a system will work long enough and efficiently. But it is always necessary to remember about subzero temperatures, so it makes sense to insulate pipes passing from the well to the house. For example, the pump station for the Abyssinian well is installed on the surface, since it is not possible to create a platform underground. In this case, it is advisable to transfer the pump to a heated room.
A little bit about how to choose a pumping station
In order for the acquisition to be appropriate, it is necessary to be guided by some parameters. One of them is the power of the pump. This parameter is extremely important. The fact is that insufficient productivity will contribute to constant loads and equipment overheating. At the same time, a large supply of power is a waste of money. It is necessary to be guided here by the amount of water consumed per hour. The reserve capacity of the pumping station should be at least 5% and no more than 15%. But you should pay attention to the well. For example, its greater depth requires the installation of more powerful equipment or a submersible pump. At the same time, diameter is important. Although this parameter can be ignored in some cases, but if you are dealing with a well, then it is required. Installation should only be performed after all calculations have been completed. Installation can be done by yourself, however, you must follow the sequence of actions and technology. In this case, your pump station for a well will work without problems. The price largely depends on the manufacturer. Typically, prices start at 10,000 rubles. For example, the Sprut AUJSP 100A will cost 9-11 thousand. In this case, you will receive a unit with a capacity of 2.3 meters cubic per hour with a pressure of 36 meters.
What do consumers say?
We have already figured out a little with you how to choose a pumping station for a well. Customer reviews and expert advice can greatly help you in your choice. For example, people do not recommend buying some models for a number of reasons. But other pumps, even from little-known manufacturers, are very high quality. Moreover, their price is significantly lower than European products. Many advise the brand "Octopus", as well as "ALK". Consumers say that the manufacturer offers a fairly good selection at affordable prices. Most importantly, with proper installation for several years there are no problems. Some negative reviews about pumping stations are in a small resource of the main working body. How much the pump will work, it is better to check with consultants.
About Grundfos
This manufacturer is engaged in the manufacture of modular pumping stations. We can say that in the Russian Federation and the CIS countries this is one of the most famous and popular brands. This is largely due to affordable price and good quality. The modular systems from this company are designed for drainage, ordinary and treated sewage, as well as rain and surface water. The main advantage of such stations is that they are made of corrosion resistant material. This significantly extends the life of the pump and the plant as a whole. The Danish company makes quality products, so the pump station for the Grundfos well will cost you about 35-40 thousand rubles. For example, the MQ-35 model will cost about 36,000 rubles. But such equipment is equipped with a soft start system, has overload protection and much more. Engine power is 850 watts, which is enough to ensure a productivity of 3 cubic meters per hour and a pressure rise of 36 meters.
Conclusion
As you can see, the well for the pumping station can be used the most common. A shallow well will do. In any case, the greatest attention should be paid to the installation of equipment. It is on how well you installed the station, and the effectiveness of its work will depend. Of course, when choosing, pay attention to what consumers write about a particular model. Not always a well-known manufacturer is the guarantor of quality. In addition, it is not worth buying a used station for a number of reasons. Firstly, you will not receive any guarantees, and secondly, it is not known what is the resource of the pump.
