As for equipment home tanks water, spend imported water can anyone, the more significant disadvantage of this solution is, the water in the hot weather quickly deteriorates and gets an unpleasant odor. A well or borehole will be the best solution in ensuring a country area with water. To dig a well it is necessary to plan its size, the minimum depth for well 9 meters, if water is necessary to equip the cottage – not less than 20 meters. Hot on first glance, the construction of a well will seem like a cheap lesson, do not forget about the cost of equipment for pumping water, which will bring a lot of costs.
Submersible and surface pumps
Regarding the latter, they are usually installed on the surface and due to the fact, their capacity is not large, water flow from depths not possible.
Pumps, which are immersed in water, with such problem did not face, their scope knows no bounds. These units can pump and pump out the water, as well as feeding it into the supply system. Various waterfalls and fountains, decorating garden area, also use the help of submersible pumps. Another plus of these devices – "smart watering", which allows the owners house to forget about the self-watering kitchen garden.
Borehole and well the device pumping water
Well the appliances are arranged so, that intake of water at the bottom. This is necessary in order, what would the pump was cooled by immersion in water (accordingly, overheating does not occur). There are models of pumps, equipped with float switches, which disconnects the pump when there is no water in the tank.
With regard to downhole devices for supplying water, that such a task can handle any submersible pump. Wells are considered the best option for suburban area. Drilling depth depends on water quality. If the water contains impurities of various metals, the depth of the well shall be not less than 60 meters. It is also necessary to install water filters, which will cope with contaminated fluid and make it suitable for human consumption. For that would initially get clean water and to save on buying filters, must drill a well to a depth of 110 to 140 meters. At this depth is characterized by a large pressure jet, so, will need a powerful device for supplying water to the surface. Depth figured out, but what should be the diameter of the hole? The optimum diameter is only 3-4 inch.
Another advantage of borehole water consumption is, what contaminants does not interfere with the operation of the pump. Sometimes these pumps can, also, use for horizontal pumping water from rivers or lakes (this method is used, even if the pond is far from home).
Centrifugal and vibratory pumps
Vibration pumps are often used for equipment of wells, because. they cope well with the workload while its low cost and power.
As for centrifugal pumps, they are perfect devices, which can be applied not only in wells, but wells. Such devices are classified on 2 view:
- Screw (relatively inexpensive pumps, is able to pump liquid with impurities up to 300g/m3)
- Eddy (powerful units, reacting to all the impurities in the water)
How to pump water with a pump?
Sometimes there is a need not only in the tabulation of water to the house, but, on the contrary, in the deliverance of the land from unnecessary accumulations of fluid (for example, in the sewers). For this job will suit a garden submersible pump, or better yet, device – drainage submersible pump.
The pump can not only clean drains, but and drying the basement, to remove the dirty water from the pool, and also to clean the well from clay and sand. Small size, low price and a rare need for a specialist service allows you to purchase a unit for your garden.
Features of pump operation depending on the kind of impeller
There 4 main types of impeller pumps for cleaning and supplying water:
- Pumps with multi channel impeller, which serve for pumping of a weakly polluted water (for example, rain). Particle size, are able to pass through a pump, is not more than 10 mm, in the case, if the particles are more unit quickly fails.
- Pumps with single channel impeller. As a rule, more powerful and capable of flowing particles of greater size (possible even pumping fecal waste).
- Pump with open impeller is used for cleaning dirty water, and does it quickly and without problems. Use this unit to clean waste pits and sewers.
- Drain pump is the most hardy and best device for cleaning dirty water. This pump has a macerator, which is installed at the entrance and use the grinder breaks larger particles into smaller ones.
With regard to the design of all of these pumps, it should be noted, most modern units equipped with automatic, which does not allow them to work in idle mode. Appearance of pumps is determined by the material, they're made of.. Mostly plastic, stainless steel or cast iron. Cast iron pumps are capable of processing the particle size to 35 mm, which can be ¼ of the total volume of the liquid.
The principle of operation of the pump is, that the wheel with the blades, inside the pump, rotates, with the result that the water flows into the unit and using the centrifugal force created by the fluid supplied through the pipe to the intake.
How to choose the right submersible pump?
Any pump there are two main characteristics, that affect its price is the pressure (feature, which shows, how high the device is able to push out the water) and the amount of liquid pumped per unit time (mainly 1 a minute).
As for the noise, created by the pump, it should immediately draw attention to the fact, that NTP has not yet reached a completely silent pump, so during the day the unit is muffle everyday sounds (the noise of leaves, the tweeting of birds, etc.), but at night its performance may slightly disturb sleep.
In order, that would be to choose the right pump for your home, you must first calculate the daily consumption of water. On average, one person is plenty 1000 liters of water per day, therefore, using simple arithmetic you can find out, how much water will be required for the whole family for a day. It is also necessary to add to the result the amount of water, need for irrigation (2000 liters per day will be enough).
With regard to the loss, it is necessary to consider that fact, that when the delivery of liquid directly to the house, the head losses will be 1 meters 10 feet of pipe.
To determine the correct pressure needed to the height of the house to add 6 meters, the obtained result multiplied by 1,15 (the ratio of possible losses). If the pump is used in wells, need the total to add depth.
How to install a submersible pump?
That would not take the risk, I advise you not to spare money and to hire for the job of professionals in this business. But if you are a person with a technical specialty and a good host, try to install the pump at the dacha with his hands!
For the beginning measure pressure with a gauge and a special forceps supply current. Then note the time for complete filling tank, the volume which you know is going to show you the water consumption.
Next, examine the wiring diagram of pump, safety and is attached to the Assembly documents.
Now you will need a cable, safety rope, staples, hose and pipe. If the pump will be irrigated, don't forget the hose the required length.
Now go to connection and lowering the pump. First connect the unit with the pipe by means of couplings. After that, the electric cable must be attached to the bracket on the pipe. In any case it is impossible to lower and lift the pump by the cable, this is a safety wire!
Now proceed to the most crucial moment – the sinking pump. This should be done gently and smoothly. As soon as I lowered the pump, check it for safety (ground, insulation, etc.). If everything is in order, turn on the pump and allow it an hour to work in idle, then you can connect the load!
