Purpose of the pump and method of use
The pump is a device that allows cyclically to drive water through the established circuit. Often the equipment is used in decorative hydraulic structures and in summer cottages and country estates.
The principle of the mechanism is that the device creates a positive pressure, pushing the water with a certain force. The power level corresponds to the height of the ejected jet.
Country-type pumps are distinguished by their priority for seasonal mobility. The unit is convenient in that its operation does not require any additional extensions and communications. It copes well with pumping water without the need for connecting plumbing.
Virtually all pumping equipment consists of similar parts: a rotating engine and an impeller, which influences the flow force.
Before you install the water supply system, it is recommended to calculate everything correctly.
When choosing equipment, it is first necessary to compare the power of the device with the dimensions of the bowl of an artificial reservoir. In most cases, the height of the fountain jet collected by such a system should not exceed one third of the width of the reservoir itself.
Naturally, the flow rate depends mainly on the size of the tank. In order to achieve a height of 1.2 meters, it is necessary to pump about 800 liters through the pump system. at one o'clock. This is a fairly small amount compared to other devices that push water about 2 meters in height and pump about 3000 liters. at one o'clock.
A feature of the pump is the ability to provide continuous circulation of fluid. If an architectural idea is present at the site, for example, a decorative cascade waterfall, water circulation is necessary. Because in the absence of a special technique, water simply cannot rise to the top of the scenery.
Types of pumping equipment
Circulation pumps for artificial reservoirs are divided into two main types: submersible and surface. Submersibles do their work directly at the bottom of the reservoir. Surface mounted near the shore, so they do not come into contact with water.
Characteristics of submersible models
Speaking of submersible pumps, the first thing to mention is a relatively easy installation method. Such devices are used mainly in the construction of small fountains, not exceeding the height of 2 meters.
To ensure proper operation of the installation of the pump is recommended using additional components. This number includes all kinds of substrates and frames that prevent the ingress of sand and silt into the mechanism of the device. In most cases, use ordinary bricks, of which is constructed a kind of pedestal.
The pump draws water from the lower layers of the reservoir and then discharges it through the nozzle. The jet is sprayed directly above the unit, but when a hose is connected to the device, it can be brought to the place given by the idea of landscape design.
The connection of the two elements occurs through a plastic or rubber tube. Often the length of the pipe is dictated by the power of the pump. The greater the distance between the modules, the more intense the flow should be. Pipes are connected and lengthened according to the telescopic principle.
It should be remembered that the pressure from the pumping system to a large extent depends on the cross-section of pipes and supply hoses. The narrower they are, the greater will be the flux density at the outlet, therefore, the jet will be more intense.
As with any automatic system, the submersible pump operates from the electrical network. According to the basic rules of installation, the system must be grounded. To work, it will be enough voltage at 24 V. Devices of this type are low-voltage, so the power source can act as a normal transformer.
It is quite another matter with high-power devices. As the number of handsets increases and additional structures are connected, more energy is required. Consequently, such systems are already connected directly to the network using an electrical cable. In order to avoid emergency situations, the power harness must be necessarily covered with a waterproof material.
An important factor is the presence of sand particles and other pollutants in the water of water bodies. Most submersible systems are designed for pumping almost pure water.A number of models allow the presence in water of impurities in a volume of 50 g / m³ and large particles, the size of which does not exceed 0.2 mm. To prevent damage, each pump is equipped with a filtration system, which is included in the design of the primary module, located under water.
In the technical documentation attached to the submersible pumping units, the allowable interval for the acid indicator of water, salinity and the maximum possible temperature for pumping are indicated. The manufacturer’s instructions must be carefully observed so that the pump does not fail before the deadline.
Submersible pump motors are continuously cooled as the pumping water runs. The design of the equipment provides support for thermal equilibrium and protection of the contacting parts from premature abrasion.
It is necessary to select the pump so that the process of work is carried out at medium speed, while achieving the required power level. If the pump is constantly laid out to the full, the working life of the unit will end faster. In this case, it is advisable to replace the equipment with a more productive one.
Another advantage of submersible pumping devices is the noiseless mechanism. Since the main noise generator is under water, from the shore it is almost inaudible. Also, the power consumption of the device is relatively small, which increases the degree of savings.
If repair is necessary, the submersible device must be disconnected and removed from the reservoir. Simple repair operations without problems can be carried out personally.
Description of surface systems
For the construction of multi-level structures are mainly used surface pumps. Convenience of operation of this type of the equipment consists in simplicity of service. Compared to the immersion counterpart, it is much easier to detect a breakdown, if necessary, to fix it.
Surface pumps are less sensitive to water pollution, clay slurries, and organic matter. They are capable of pumping water from open, not equipped reservoirs without causing damage to their own mechanics.
For water intake into the pond or fountain tank, only the hose attached to the inlet is lowered. If the water to be pumped is unnecessarily polluted, it is advisable to equip the hose with a bottom valve with a fine filter screen.
The disadvantages can be attributed to poor resistance to moisture and overheating from direct sunlight. To maintain high quality performance, the device should not be left out in the open.
Manufacturers recommend constructing separate boxes for such equipment or small pavilions that will protect it from precipitation.
A weighty lack of surface pumping systems is high noise.Since the equipment is not under water, the process of its work is perfectly audible to others. To avoid such situations, it is desirable to sheathe the protective housing or pavilion from the inside with sound absorbing material.
The power of the device depends on the distance to the reservoir. If you connect to the surface pump too long hoses and all kinds of nozzles, the efficiency of the device will be significantly reduced. Therefore, manufacturers insist on installing equipment in the immediate vicinity of the reservoir and indicate the maximum allowable distance for its work.
Often, two objects are connected to such a system at once: a fountain and a waterfall. According to the instructions, the water pressure for these elements should be different. Hence the conclusion that when branching the water pump and connecting two hoses, you need to properly adjust the power level of the flow.
To be able to connect two circuits to one pumping device, it is advisable to purchase a tee if it was not in the original factory configuration.
This is important to understand before the installation process, because it often happens that the characteristics of the device become a complete discovery after the detection of inoperability. It is better to thoroughly familiarize yourself with the technical data of the pump, and then only proceed to the installation.
Technical features of devices
In most cases, landscape designers use a pump for fountains or waterfalls, but there are still decorative complexes. This is typical of design ideas that emphasize the particular style of the landscape.
Architectural compositions in the form of mermaids, corals and other elements of the marine theme are often used as the final module of the water-pressure system. To do this, just there are special models of pumps that do a good job with the task of supplying water.
To add variety to the fountain, most manufacturers include several nozzles that change the shape of the jet.
Filtering qualities are undoubtedly important for the proper operation of the system, but for the most part they do not provide bactericidal properties. Some fountains have this feature. The effect is achieved thanks to the hardware components, namely, ultraviolet lamps. Systems with a cleaning module for microorganisms and their metabolic products are respectively more expensive.
As a result, the percentage of germs causing water bloom has been significantly reduced. Plus: ultraviolet will favorably affect the reservoir's fauna if it is planned to breed river animals, for example, fry.
These properties are inherent, for example, to the Gardena FFP5000 fountain. The disinfecting effect is fully felt only in reservoirs up to 5,000 liters. If the tank exceeds the recommended capacity, you need to install another model with a more powerful UV lamp - Gardena PF 15000S.
In addition, the decorative aspect of the fountain implies a special depression in the upper part of the sprinkler. The cavity can be filled with any material, be it crushed stone or another granulate. Such design will successfully fit into a country interior.
The popularity of equipment is mainly due to the relatively low price, and because of the small size of the unit there will be no difficulties at the stage of its installation.
If a waterfall is planned on the site, it is better to use units that can pump dirty water. Such a device is not afraid of pollution and inclusions found in open natural waters. Large fragments of algae, leaves, etc. will not destroy them.
Therefore, for taking water from natural sources, it is recommended to buy a surface pumping station, and for work in indoor pools, artificial products with injected tap water, it is advised to buy submersible ones.
Location is an important factor.
The main point, which is worth paying attention to when building a fountain, is the angle of inclination of the terrain. It is noted that for the harmonious operation of the waterfall is better when the land is a little flat.
The construction of the fountain is best carried out directly in the lower part of the improvised slope. This will prevent an undesirable rise in the groundwater level.
The fountain is first of all an aesthetic object, therefore the visual component of the structure is undoubtedly important. If the fountain pump does not have a filtration system, the water will bloom quickly under the influence of intense solar illumination. Because of this, there will be an unpleasant smell.
It follows that it is necessary to carefully select the area for the location of the building. It is not recommended to erect a fountain in an open, continuously illuminated area. In the spring and autumn, the appearance of algae is not catastrophic, however, in the summer season it really delivers a lot of problems.
Another important factor is the proximity of trees. The root system of any deciduous tree occupies a rather impressive area. If you do not calculate the possibility of crossing the outer wall of the reservoir with the root, may be the destruction of the bowl.
Types of fountains:
- Geyser- mainly decorates the open areas of the holiday complex. Due to its design and pressure, a fountain of this type is well resisted by gusts of wind;
- Bell- the fountain head is not very high, but the visual effect is interesting and will fit well into the composition of small country houses;
- With jet separation system. The fountain can create jerky drops flying along a predetermined path. This type of equipment is appropriate in open areas.
In addition, the fountains are installed not only on the street, but also there are models specifically for the house. The design of such devices is not protected from moisture and wind, and therefore can not be used in open areas.
Landmarks for a weighted device purchase
The primary factors affecting the cost are the type of fountain and its capacity. Submersible equipment is usually more expensive than the surface, because in its manufacture uses specific materials that are resistant to underwater pressure and constant contact to not always innocuous water environment.
Often, manufacturers include certain add-ons.The presence of various modules and attachments is determined by the specific model of the unit. Visual effects affecting the price include the presence of a backlight and a UV emitter.
All of the above, of course, can affect the cost, but the main price corridor depends on the name of the manufacturer’s company and the dimensions of the fountain to be bought.
In order to maximize the choice of the pump and correctly evaluate the proposed functions from a practical point of view, you should be guided by a number of points.
- First choose a device with a full set of additional extensions. This includes nozzles and hoses, a system for regulating water flow, as well as several spray heads.
- Correctly match the size of the pool with the power of the unit.
- When organizing a multi-level fountain or waterfall, the best performance is shown by water installations of the surface type.
- Quality models are resistant to corrosion.This should not be neglected, since the device is always in the water or near it. The right choice of protective coating will significantly extend the life of the equipment.
- Always ask for instrument documentation. Verify the authenticity of the documents and the availability of quality certificates.
- Pay attention to warranty features. Examine the purchase agreement for availability of service warranty items.
- Connecting the power supply, make sure that the system is equipped with a special fuse that can at any time stop the flow of current. This is not a joke, because it often happens accidents associated with the violation of the sealed sheath of power cables.
Observing all this, you are guaranteed to get a quality product that will serve for many years. Water compressors for the fountain differ in a variety of shapes and sizes, and manufacturers constantly make adjustments to the equipment, making it even more reliable.
Features of the installation of pumping equipment
At the installation stage, you need to decide on the type of pump. If the tank capacity is not too large, the choice of a submersible model would be an excellent option.Due to the design features, the device must be installed on a special frame, preventing contact of the device with an oozy bottom.
Bricks are well suited for such purposes (sometimes you can use an inorganic material, such as plastic). It is strongly not recommended to weld the metal substrate, since permanent residence in water will lead to rapid oxidation and the structure will collapse.
The upper part of the device should be connected to the pump with a rubber or plastic tube. There are models with corrugated hose to avoid deformation. Never install pumping equipment in winter. Freezing damages the device and can lead to a forced repair or completely spoil it forever.
Care must be taken when installing a submersible pump and monitoring water levels. Intensive drainage of a natural reservoir can lead to serious damage. This is primarily due to insufficient water levels.The equipment is designed in such a way that work in idle often leads to irreversible consequences.
For example, in the absence of a fluid that acts as a lubricant for moving parts of a mechanism, the contacting parts wear out quickly. Consequently, the pumping station will not last long if it is not deeply immersed in the reservoir or is operating without immersion longer than the period allowed by the manufacturer.
Like any electrical equipment, the pump needs to be grounded. When organizing the power supply, take care to properly connect the power harnesses. It is better to do this under the guidance of a person who understands electrical appliances.
Ideally, it is better to contact the service center of the company that deals directly with the installation of equipment. Of course, this option is much more expensive, but you cannot save on security.
