How does a pumping station work?
A pumping station is a complex of devices consisting of a pump, storage tank with rubber or membrane insert, pressure switch and control panel.
The principle of operation of the station is quite simple. The pump pumps water into the hydraulic tank, here the water is under a certain pressure, which depends on its quantity and the volume of air in the tank. As water is consumed, the pressure in the accumulator decreases.
Configured accordingly pressure switch captures the change in the amount of water. Upon reaching the minimum settings, the relay switches on the pump so that the hydraulic tank is filled with water. As the tank fills, the pressure increases, the relay fixes its maximum level and turns off the pump.
The on and off cycle is repeated in such a way that the amount of water in the tank is constantly available that can meet the needs of the residents of the house.
Such a system is highly efficient. For example, if the water supply was connected directly to the pump, the equipment would have to be turned on every time someone opened the tap.
The presence of a pumping station with a hydraulic tank allows you to reduce the number of on / off pump to the required minimum. This significantly saves the life of the equipment, extends its service life. Since the water in the hydraulic tank is under pressure, a good pressure can be created in the entire water supply system of the house.
An acceptable indicator is usually about 1.5 atm, but it can be increased if necessary. Separate household appliances (washing machines and dishwashers, Jacuzzi bathtubs, showers with hydromassage) in the absence of sufficient pressure in the water system just can't work.
The pump station effectively solves this problem.
If, for some reason, access to water is limited or absent (breakdown of the pump, a sharp decrease in the flow rate of the well, etc.), the supply of water in the hydraulic tank will be very useful.
Water can be used for some time until access to water resources is restored. If a pump is used instead of a station, turning it off automatically deprives water of all residents of the house.
Features of installation and operation
The pump station can be assembled independently, but it is easier to buy a ready-made unit. These devices are relatively simple in installation and operation.
To install the station you will need a flat area and shelter from the weather. The hose of the surface pump is lowered into the well or well, the hydraulic tank is connected to the water supply system of the house, and I provide the entire system with power (need RCD).
After that remains set pressure switch and start operating the station. Further intervention in the operation of the device is usually not required.
The station will replenish the supply of water in the hydraulic tank in automatic mode. It is recommended that approximately every three months, the operation of all elements of the pumping station be checked. As necessary, carry out maintenance of individual components: flushing the pump, adjusting the pressure switch, replacing the membrane in the hydraulic tank, etc.
If the pumping station is selected and installed correctly, it can work for many years without interruption.
The problem of choosing a pumping station
Such equipment is offered to the consumer in a very wide range.
Models of modern pumping stations differ in a whole set of parameters, such as:
- place of manufacture;
- brand name
- accumulator volume;
- power consumption;
- design features;
- equipment, etc.
At choosing a specific model the pumping station should first carefully study the conditions of its operation. If a well serves as a source of water intake, you should carefully study the construction passport, it contains a lot of useful information.
If there is no special technical documentation, you will have to find out the characteristics of the well yourself.
Here is a list of indicators that you should focus on when choosing a pumping station:
- well / well flow rate, i.e. amount of water delivered per unit of time;
- statistical and dynamic water level in the well;
- the height at which water will have to be supplied;
- distance from the source of water to its place of consumption.
Productivity is one of the main indicators when choosing a pumping station. It characterizes the maximum amount of water that can be delivered to a house in a certain period of time.
First you need to calculate exactly how much water will be needed. At the same time, the number of people permanently residing in the house is taken into account, as well as the presence and characteristics of household appliances that use water: a washing machine, bathtub, hydromassage, etc.
In this case, the parameters of the pumping station should be correlated with data on the flow rate of the well or well. Problems may arise if water is taken from the source more intensively than natural replenishment. In such a situation, it is likely that one day the well or well will be empty.
And this will lead to the equipment in dry running mode. Therefore, if the performance of the pumping station significantly exceeds the flow rate of the structure available on the site, it is worth looking for a more suitable model.
Typically, for the organization of autonomous water supply in a private house, pumping stations are selected, the power of which varies between 3-6 thousand l / h.
To roughly imagine the necessary equipment performance, you can focus on the following information:
- Peak water consumption at the summer cottage is usually about 0.8-1.5 cubic meters. m / h
- A family of 4-6 people living in a medium-sized cottage consumes about 1.5-2 cubic meters. m / hour.
- For a large country house, taking into account the need for watering, maintenance of the pool, fountains, etc. the need for water will be at least 3-4 cubic meters. m / h
The power of the pumping equipment can be 0.6-1.5 kW.Here, not only the amount of water that needs to be pumped into the house is important, but also the distance from the point of water intake to the point of its consumption, as well as the height that the water column will have to overcome in order to get into the house.
The more these indicators, the more powerful equipment should be chosen.
The depth at which water has to be taken can be of decisive importance. Usually pumping stations are equipped with surface self priming pump, which is effective at a depth of 6-8 m. Owners of deeper wells, as a rule, should use more powerful submersible pumps.
You can solve the problem using a self-priming pump with remote ejector. This is a more complex device, but it allows you to increase the depth of water intake to 30 meters and even more. Moreover, such equipment can be used in standard four-inch wells.
Of course, the dimensions of the hydraulic accumulator tank deserve attention. You should not choose a container that is too large in volume, since it will gain significant physical weight when filled with water. Hydraulic tanks are usually made of stainless steel, as well as cast iron or plastic.
For long-term use, taking a plastic container does not make sense, it has a too short life. Cast iron tanks are exceptionally reliable, but have a high cost. Light, relatively inexpensive and durable steel is used for the manufacture of hydraulic tanks most often.
The inner liner made of rubber may have a pear shape or be made in the form of a membrane. Since this element experiences a constant and at the same time changing load, it may fail over time. When choosing a pumping station, it makes sense to think about the possibility of replacing the tank liner.
The cost of the pumping station can be significantly affected by the presence of protective modules. This equipment allows you to automatically turn off the pump, if the source has run out of water. If you do not turn off the equipment on time, working in idle mode will cause the engine to overheat, resulting in significant damage.
In some cases, it is necessary to completely replace the engine, pump or the entire station. Is it worth it to spend money on a pumping station with an automatic control unit? On the one hand, this is a very convenient module, on the other - additional expenses.
In almost all cases, automation is an appropriate acquisition, especially when it comes to supplying a large house with water for a whole year. Manual control of a pumping station should be considered only if it is purchased for a small cottage where such equipment is used irregularly.
Recommendations for the selection of equipment
Pumping station - equipment is not cheap. When choosing a suitable model, it makes sense to pay attention to the products of well-known brands with a good reputation.
Too low a price is not the best indicator for a pumping station. Typically, such units have quality problems that will appear only during operation.
The most important point is after-sales service and warranty. The product must be equipped not only with a technical passport and detailed instructions, but also with properly executed warranty documents, which should be carefully studied.
The long warranty period of an automatic pumping station usually indicates its high quality. You should also familiarize yourself with the procedure for providing warranty services.
It happens that for pump station repair under warranty, you have to go to the nearest city, region or even send broken equipment to a neighboring country, and this is long and extremely inconvenient.
At the end of the warranty period, repairs and maintenance will have to be done independently. You need to make sure that the materials, spare parts and components necessary for this are on sale, so that you do not have to wait for months to deliver the item you need to repair the station.
Usually there are no big problems with pumping stations of well-known foreign companies, since they have not only a wide dealer network, but also an established system of after-sales service for their products.
It is worth paying attention to domestic products, which with high quality can offer more attractive prices for pumping stations.
