For the extraction of water, there are about a dozen speciesspecial machinery. One of these units needed in the economy performs motor pump for watering the garden. It is equipped with a water pump, a mobile station, which is indispensable in suburban areas for arranging irrigation systems or create a private water line. This technique is not only used for pumping water from wells and wells in order to further use it as irrigation and domestic needs, but also for the cleaning liquid and even sewage pits.
Stand-alone units can significantlyfacilitate farming on neelektrofitsirovannyh suburban areas. Motor pump is quite simple to use: it is easy to manage any landlord who owns the basic skills of working with technology and has a view of the internal combustion engine.
The main advantage of motor pumps is their compactness and the possibility of use in a wide range of works
Motor-pump is easy to transport and requires special storage conditions. It is easy to carry on site for the convenience of dismantling the suction and discharge hoses.
The principle of operation of the system is that underthe influence of the movement of the impeller centrifugal effect occurs, which drops the water in the pump housing in the "snail", forming and directing a jet of water to the nozzle. As a result of discharge that occurs near the axis of rotation, the valve opens and the liquid enters the nozzle. Water intake and feed it to the pump through the hoses attached to the nozzle.
To protect the pumping unit from falling coarse end of the suction hose equipped with a strainer
Performance indicates the amount of fluid that the pump is able to pump a minute. It is this parameter is determining the appropriateness of the use of the unit for the specific conditions.
For the everyday needs of a small suburban areawatering the garden or organization motor pump unit is sufficient capacity 130-150 l / min. Planning at home provide a water supply, a more powerful machine, whose capacity ranges 500-1000 l / min.
If the motor pump is designed fordraining flooded areas, in fire fighting and other emergency situations, it is better to stop the choice on units with high performance in 1000-1200 l / min.
Depending on the type of engine-driven pump are:
Power units on the gasoline engine canbe up to 1600 liters / minute, so that they are effective both for pumping pure water and polluted liquid. Motor pump, running on gasoline, are most popular among the owners of suburban areas. The popularity is due to their use of simple operation, high efficiency and relatively low cost units. The only disadvantage of these types only high fuel consumption can be considered as models.
Petrol units are equipped mainly two- or four-stroke engine and run on a mixture of gasoline and oil
The main advantage of the motor pump on the diesel engine is their reliability and durability. They are capable of pumping viscous liquids even
Compared with gasoline counterparts, thelife of the diesel units is much higher and can reach 6000 hours. They are able to provide uninterrupted continuous operation with a fairly low fuel consumption. However, unlike gasoline models are quite noisy to operate. Though initially the cost of diesel engine driven pumps is high enough, but it quickly pays for itself due to the low price of diesel fuel during operation.
The smallest spread in the conduct of countryEconomy got gas pumps. The reason for this is their high purchase cost and the need to maintain special conditions during operation.
Due to the fact that gas, unlike gasoline anddiesel when burned does not form ash and waste the working surface of the unit is less wear and engine life is extended considerably.
The sale can be seen as a model, working exclusively on gas balloon, and more versatile units that can be connected and the highway.
This option, as the water pressure at the outlet ofpumps, determines the distance over which the unit is able to transmit the water's uploaded. This setting can not be overestimated in those cases when it is necessary to work in a drop height to which water must be pumped to raise.
For watering the garden and other economic goals enough pumps with a pressure of 25-35 meters, but still better to buy a model with a pressure of up to 65 meters and more
Depending on the application pumps are divided into two subspecies.
These units are designed for fillingtanks, pumping water out of the pool and watering the garden. They are equipped with filters capable of capturing particulates in excess of 6 mm, so that the water after filtering becomes relatively clear. On average, the performance of two-stroke engines with water pumps for watering the garden is 6-7 m³ / h.
Water from swimming pools, wells and springs is considered to be relatively clean. It is substantially free of impurities, debris and large dirt particles
Mobile pumping station for clean water easily fit in a backpack; they are light weight and small dimensions.
These pumps are designed for pumpingflooded areas, as well as clear the contents of wells and septic tanks. They are capable of pumping fluid in the composition of which can present a sufficiently high concentration of lime, clay, sand, silt, gravel or crushed stone. Such models are equipped with filters, free flowing solids with a diameter of 6-30 mm.
The main advantage of such models is the high performance and excellent bandwidth. These pumps can be operated for a long time and with high intensity.
To cope with very dirty water containing sand, coarse particles of dirt and leaves, can only pumps for heavily polluted water
To choose the best option amongmotor pumps diversity of models, it is necessary to clearly define the purposes for which it will be used. But in any case, the assembly with a gasoline engine adapted to pump dirty water, it is easy to handle and clean water. However, during operation it will exhibit a higher fuel consumption than the same model, but with a diesel motor. It should also be borne in mind that the closer the motor pump will be located to the point of water intake, the lower the load on it.
