Sades - the people are inventive. Cottage, as a lifestyle, makes it possible to solve the most difficult tasks yourself. And this is probably the main highlight of the ownership of the country. This review about pumping unwanted melt water from the cellar when the flood fills the basements with valuable dachas. And about a more global task - the supply of water into the country area. All these questions are able to solve household submersible pumps for water. But we will not get ahead. About everything in order.
What it is - submersible pump
In order not to dissolve pseudo-contagious conversations, say simply - the submersible household pump falls into the water entirely or partially and allows you to pump water or to get rid of the unwanted consequences of floods, pumping out dirty water, or for the fence of drinking and technical water from wells and wells. Such pumps are conveniently used for watering the beds and flower beds and other similar needs.
Types of submersible pumps
Before you buy a submersible pump, it is better to know his specialization to know exactly - what exactly you want from it. From the scope of its application will depend both the cost and its main performance.
According to the type of application, it is conventionally split them.
Security submersible pumps
They are used to provide water cottage house or a small country house. Their main task is to raise pure water from the well or a shallow well. Such submersible pumps are not lowered at the very bottom of the well or well - then the filter clogs, and the sediment will rise in the source.
Borehole pumps
Borehole pumps for order technologically and will cost a little more expensive. For example, the high-end pump "Sprove 100" with 1 kW and the remote control unit will cost you 12,000 rubles.
They look like a spacecraft from fantastic films of the 80s - have a small diameter, the form of a cylinder and such a size that allows them to be placed in a well at great depth. When choosing a well pump, it is necessary to consider such parameters:
- the height for which water must be lifted;
- power;
- depth of immersion in the well;
- performance;
- well diameter;
- type of case material;
- power cable length.
Make sure that the diameter of the pump housing was 10-12 mm less than the well column. Otherwise, it can bother there that will complicate your life.
Drainage submersible pumps
In the selection of dirty water from cellars, cellars, garages, weighing drainage pumps. The use of the submersible pump can very care if there is a sudden flooding in the event of abundant precipitation or when an accident in plumbing systems. They are just perfectly suitable for the irrigation of flower beds, gardens and flower beds. But you need to know that their design allows you to pump water with fractions not larger than 30 mm.
The cost of the submersible pump depends on its power and manufacturer, but on average, the pumps for the country area do not cost more than 3,000 rubles with a height of water supply from 5 m.
Fecal submersible pumps
They are used to pump dirty water from cesspools, septicists, household waste tanks. They are much more powerful than drainage models and can cope with a large number of pollution. Many models at the entrance are shredders, which grind large fractions.
Fecal pumps are used with additional filters, which affects their price. Many enjoy German Verk pumps. With excellent quality of manufacture, judging by the reviews, they allow you to pump 330 l / min, and relatively inexpensive - 6,000 rubles are quite reasonable for it.
By engine location, submersible pumps are divided into two categories:
- rod pumps. The electric motor is deposited on the required distance from the pump and is on the surface. The drive on the pump mechanism is performed using a rod. More often they are used as industrial submersible water pumps.
- breaktant submersible pumps. The engine is mounted in one case with a pump and immersed in water. Due to their compactness, they find wider use in everyday life for clean and hot water.
Device of the submersible pump
Any submersible pumps are mounted in a durable case, which reliably protects the mechanism from water. According to the principle of operation, such pumps are divided into vibration and centrifugal.
The vibratory submersible pump serves water by vibration. Because of this feature, it is not recommended to install too close to the bottom. Due to vibration, such a pump can raise the well and sand from the bottom of the well, which will lead to an increased content of sand at the outlet.
Centrifugal pumps are injected with water vane principle. The centrifugal force of the rotating paddle rotor discards the fluid on the walls of the chamber and as the pressure is injected to feed it out.
All modern well submersible type pumps are designed for long-term work at high loads and are able to create sufficient pressure to supply water to a large height.
Calculation of the performance of the submersible pumping water pump
Pressure and performance. These are the main indicators that should be interested in us during the selection of the submersible pump. You just calculate them. Knowing the consumption of water consumption for 1 person per day and on watering 1 m² of lawn or a garden, which averages 200 and 3.6 liters, respectively, it is easy to find out the power of the pump that we need.
To do this, find out the pressure. Under pressure implies the height to which the pump can feed water. Experts recommend to take into account such a coefficient - 15 m of the head corresponds to 1.5 atm. Consequently, if we need to raise water to a height of 20 m, the pump must create water pressure at least than 3 atm. But, we are not enough just to raise water from the well. It is also necessary to make it raise it from the crane.
Now we use the formula for the final calculation of water pressure.
H.=hS.+0,2L.+30, where
- H is the minimum allowable wound post, it is indicated in the pump characteristic;
- hs - pump immersion depth;
- L is the length of the pipe from the well to the entrance to the house.
We leave the reserve within 15% to reduce the load on the pump and accept the received number to take note when buying a device.
Rules for the installation of a household submersible pump
Installing the pump will not cause any difficulties, if you follow simple rules.
- Fix the hose on the pressure pipe of the pump hose.
- If the pump is three-phase, then you need to check the direction of rotation when it is connected to the power grid. It should rotate clockwise.
- We install the pump in a vertical position with a nozzle up.
- We lower the pump in the well or in the well using the cable.
- Fix the cable and check the performance of the system.
Features of the fecal pump
Fecal pumps work according to the same principle as all submersible pumps, but constructively differs by the presence of a chopper. The chopper is capable of crushing solid fractions into smaller, before skipping the liquid into the device body. Such a pump can be used for irrigation of lawns and gardens, dropping it to the bottom of the reservoir. Then the garden will be not only water, but also fertilizer in the form of small water plants and yals. The service life of the fecal pump is higher than that of the usual submersible. As a rule, they are manufactured from more durable materials.
