Pump for pumping water from the pool. The principle of operation of the heat pump. Pump equipment Pedrollo
A drain pump will help you quickly pump water from a pool, pond or flooded basement. Such an installation is immersed in water and pumps it out, diverting it through a special hose to either the tank or the irrigation system. The most popular drainage mud pumps are among gardeners, owners of private houses, as well as public utilities, who have to eliminate the consequences of pipe leaks and for pumping water.
In addition, an opaque winter sail prevents the penetration of light, which contributes to the formation of algae and microbes. The roof pool is only 5 cm below these components. This pipeline must have a gradient so that there is no water left in the pipeline and there are no frosts. If the installation of pipelines is more complicated, it is better to distribute and drain all pipes in the mine. If you adhere to these points, the pool will always be well kept and will not be damaged.
In the spring, we begin to prepare the garden pool during the season. We will do what the fall does not fall - we clean the clogged filtration, rinse the inside of the pool body or replace some plastic components. An incorrectly maintained pool is a source of various skin problems, so in the spring we will focus on thoroughly cleaning the filtration and the supply pipe, and we will do a full audit.
Kinds
- for dirty water - has a wide chamber, which allows water with large particles up to 35 mm in diameter to pass through it. Such equipment is suitable for pumping liquid from cesspools, flooded basements, ponds.
- for clean water - used to pump water from a pool, tank, rain barrel. Moreover, it should not contain particles with a diameter of more than 5 mm. Also, this technique can be used in irrigation systems.
Features
Reliability - The modern drainage pump is equipped with a float switch that helps prevent breakdowns. When the water level drops below the set float, the drain pump shuts off.
Circulation pumps and their tasks
Spring preparations were made easier by those who had already examined the water with the appropriate chemicals in the fall, draining the pool of solids and dropping the water level about ten centimeters below the suction nozzle of the so-called skimmer. We will not forget to dry the inlet and outlet pipes from the pump in order to avoid freezing. If we use solar panels to heat pool water, we will not even forget them. Thoroughly dry and dry the water from all the boards and clean them. Finally, we will use a chemical preparation for wintering and cover the pool with a sail.
- Water must also be drained from the pump using drain screws.
- Then store the entire filter unit in a dry place where it freezes.
Mobility - due to its small size and light weight, this equipment can be easily transported around the site and transported in a car. Many models are equipped with handles for the most convenient transportation.
Durability - since drainage pumps are immersed in water and in contact with it for a long time, their bodies are made of plastic or stainless steel. These materials are corrosion resistant.
If we use a cover, we will remove it from the pool, let it dry and dry it in a dry and cool place with minimal access to light. This is very important to maintain his long life. The second step is to thoroughly clean the pool of dirt. We are especially interested in the cleanliness of the walls, for example, removing floating contaminants such as leaves, grass or dead insects, removing dirt from the bottom with a special vacuum cleaner for the pool.
Clean the walls with a sponge that splashes on them, and let them work for about a quarter of an hour. Rinse thoroughly with a stream of water. In the event of severe contamination, repeat the procedure for best results. When the filtration is new, we must make sure that this is the so-called self-priming pump system. This means that after filling the pool we do not need to pump out the pump, the water will stretch almost immediately after starting.
Important Features
All pumps for drainage vary in power, and therefore have different capacities. For example, the Speroni TSN 200 / S HL model, designed for 200 watts, is capable of pumping up to 60 liters of clean water per minute. And the model Metabo PS 18000 SN 0251800000 with a capacity of 1100 W during the same time to cope with a volume of 300 liters.
After cleaning the pool, a filtering device is connected. Before starting, we, of course, will not forget to filter the sand of the filter - after two or three years we must replace it with a new one, because the existing one already has a reduced filtering ability due to compaction of quartz sand particles. Old sand also carries a heavy load on the pump.
An interesting addition to larger pools is solar heating. If this is a mobile device, place it so that the sun shines most of the day. If frost occurs, allow water to flow through the panels or switch the so-called bypass so that water does not enter the panels at all. After installing and preparing the filter equipment, add so much water to the pool to get a level before the skimmer. Run the filtration and let it work all day - to mix the water thoroughly and show objective data in subsequent measurements.
Pools in the country are indispensable in the summer, because it is so nice to swim in clean cool water in the sweltering heat, and in the evening to arrange a beach party right on the site. But for this, the water must be really clean.
Unfortunately, the pond is quickly clogged with sand, fallen leaves, small pebbles and ground. After winter, if you do not drain the water, it is generally not suitable for swimming. So without a pump for pumping water from the pool can not do.
Specialists in the construction and maintenance of the pool say that the pH should be between 6, 8 and 7, 4, so the water should be neutral. Acidic water causes corrosion of the metal parts of the pool, the color of the walls of the pool and, in addition, irritates the skin. On the contrary, alkaline water acts negatively in general - water is formed during decay, and chemical products reduce efficiency. The water reaction must be checked once a week or immediately when dill begins to form in the water.
Chlorine disinfects, but be careful when dosing
Drugs are known as pH or pH. In very hard, calcareous water, a water stone forms, which is very poorly removed. Today we distinguish between two types of chlorine pools in pool water. Free chlorine is released into the water by dissolving the tablets and is its most effective form.
In this article we will tell you how to choose a pump for the pool and which option will be better in each case.
Such units are submersible and surface. Their main difference is their adaptability to work in dirty water. Surface suitable for slightly contaminated liquids with solid particles up to 1 cm. Submersible ones do not deteriorate even from debris 3-5 cm in diameter and suitable for very dirty ponds, not only pools, but also ponds.
Dosing of chlorine is provided by the float, where we place the required number of tablets. The so-called bound chlorine is formed by the reaction of free chlorine with organic impurities containing nitrogen compounds. A value below this range means rapid water degradation and the risk of overgrown pools with green algae. The high content, on the other hand, has a negative effect on the skin of bathers - they may experience eczema and other skin problems or may have irritated eyes.
What do we need to do when the content of bound chlorine is high and it hurts us with an unpleasant odor? The first is to replace the water with a new one. . In superchlorination, bound chlorine decomposes without chlorine and nitrogen, which then evaporates. Since the content of bound chlorine cannot be measured directly, we will use the formula to find out.
The choice of device is made depending on its power, diameter of the intake opening, volume and contamination of the reservoir, predicted frequency of use.
A multi-channel impeller allows only small debris to pass through, for heavily polluted water, choose pumps with a single-channel wheel. The impeller can be open, this is installed in drainage pumps for pumping water from the pool.
Chlorine \u003d chlorine free chlorine. Chlorine is measured using tablets or drops, most of which are combined, which means that they can measure both chlorine and pH. Impurities are contaminated with microorganisms, which contribute to the fact that water can be harmful for some time.
To use the pool, we must learn to properly distribute all the chemicals that are necessary for its operation. Especially in the spring, this ability is important, because we actually create the basis for the entire season. But we must have a properly functioning filter. If we neglect its maintenance, we can distribute the chemistry as we want, we can do nothing - the chemicals work well, they must be thoroughly mixed with water, and clogging of the filter reduces pump performance, thereby impairing circulation in the pool.
The larger the solids in the water, the more important it is to choose an appliance in a rugged housing. Instead of plastic for dirty water, take the unit in a steel or even cast-iron case.
Surface models
Their main advantage is ease of construction and ease of installation. It is not a problem to remove such an assembly immediately after use, it is especially important if the weather is bad or you are planning to leave and are worried about its safety. They provide efficient pumping to a depth of 5 m.
We check it at least once every two weeks or under pressure on the pressure gauge - the higher the pressure, the more it is filtered. The most common are green algae and are found mainly in water with limit values \u200b\u200bof chlorine content. Algal spores contain dust, rain or wind. Sometimes, however, we also come across brown eyelashes that thrive in places with no light.
Against algae, we strive to remove algae and test the water parameters. The problem usually lies in its inappropriate composition, when it contains a lot of nitrogen or the pH does not show the correct value, and therefore the chemistry is not working properly.
Devices turn off automatically when overheating, have protection against electric shock. It is convenient to use a surface electric pump if there are several ponds in the area. To start, you only need lower the suction hose into the water and plug the unit into the mains.
Surface pumps can be produced in metal and plastic housings. The first ones are shockproof and have a longer service life. The second is cheaper and quieter. Despite the convenience of electric pumps, surface pumps are still too low for continuous use.
Water basins as such arise for a variety of reasons, with too many minerals, mainly manganese, calcium or iron. We must chemically modify such a pool immediately after impregnation - to lower pH and hardness and remove minerals that are dyes.
We use the so-called flocculant to remove turbidity. It is a chemical agent associated with small particles of impurities in water. This stretching of the particles ends with the creation of flakes, which we comfortably suck out with a vacuum cleaner in the pool. But he also has one negative feature. If we overdose the flocculant, it will cause dandruff in the water. It does not disappear until the fine dirt returns to the water and then rinses off the excess product.
It's better use them no more than once a week, which is enough to change the water in most pools. Due to the fact that the maximum particle size in water that will not ruin the pump is only 1 cm, the devices should be used in not too polluted water bodies, for example, swimming pools under a canopy.
Submersible
Pumps of this type, pumping water from the pool, can be domestic and industrial. To give enough household model. Its capacity is much higher than that of the surface, this option is suitable for frequent pumping or a large reservoir.
However, turbidity can also occur due to solar heating - we would rather turn it off in high heat. In warm and sunny water, algae also thrive. . Preventing water pollution problems also makes it easy to record inspection reports. We will know when to measure values, or when to clean the filter or change sand. Keep in mind that almost immediately after commissioning, eyelashes can get into the water and cause turbidity, as some species resist chlorination.
But when swimming, we must wait at least one day or until the chlorine content becomes normal. In this regard, we will not forget to clean the walls and bottom of the pool. If one of the bathers is allergic to chlorine, we can use the so-called chlorine chemistry without chlorine.
The device is inconspicuous, its body is sealed and, as the name implies, is under water. Wide working windows are made in the submersible unit through which garbage passes up to 5 cm in diameter. But if there are more particles, you will have to install a filter at the input.
Problems with skin eczema are mainly caused by improper dosing of chlorine when its level is so high that it irritates the skin and eyes. With proper dosing and maintaining optimal free and bound chlorine values, fears and even more self-confident people should not be worried.
Low water depletion, basement water, flooding, dam heating, pumping water from the pool - the choice of the pump. Pump Properties When pumping water from floods, rainwater from basements, pumping pools and heating a flat surface, use a pump with the following properties: - A 230 V drive, which is currently available. - The pump may not always be completely immersed in the work, so it must be cooled with dried water. - Ability to achieve the lowest possible level. water level. - Ability to pump and contaminated water. - Sufficient transport height.
Watch the installation depth. If it is less than a meter, the submersible electric pump can work poorly and even fail. For its high-quality work, the bottom of the pool should not be executed evenly, but with a bowl, the device is placed in its deepest place. So you pump out all the water, and then the pump turns off automatically.
For heavily polluted ponds, drainage pumps can be used. They cope with all waste, suitable for wastewater. Before pumping, the liquid passes through the grinder, where large particles are crushed under pressure, then the liquid is drained.
Pump selection Ideal for drainage during floods, swellings, spring water from basements and apartment heating - use submersible slurry pumps. Everything is designed for continuous immersion. For home use, we recommend a submersible slurry pump with a built-in vertical roller that can operate in automatic mode and in manual mode. At the same time, it must be understood that in order to reach a height of several millimeters, it is recommended to reduce the pump power by restricting the flow so that water remains on the pump and does not cause air to enter.
Operating principle
The submersible pump combines in a common sealed enclosure both the pump itself and the electric motor. His the principle of operation is the same for garden and drainage options. The motor rotates the blades of the wheel, and the camera is filled with water.
Under the action of centrifugal force, the liquid is displaced and enters the sewer. The hole for the fence can be both above and below. The first will not allow you to pour all the water, but the drain will not clog with large leaves and silt. Second empty the pool to a centimeter, but the cleanliness of the bottom will need to be carefully monitored.
Surface electric pumps can be vortex, centrifugal and with an external ejector. The latter are now almost never released, they were replaced by submersible.
Whirlpools are not applicable for country pools, because they wear out from the sand. For pools, only centrifugal ones are suitable.
Centrifugal models have wheels that drive a working shaft supported by bearings. The wheels build up pressure, the water rises, then drains through the outlet pipe. All electric pumps have a relay sensor, it triggered by shutdown when the water supply is cut off.
How to connect?
The electric pump can be circulating. is he drives water through a filter system and releases it back to the pool. The fluid is pumped completely 2.5 times a day, is cleaned and does not require draining for a long time. It turns out a closed system.
If we are talking about a conventional submersible pump for pumping water, then to connect it, the correct design of the entire pool is required. The bottom of the reservoir is poured at an angle, in the deepest place install the unit of the selected power. A pipe up to 15 m long is attached to it.
Water can be drained into a separate pit, sewer or used for irrigation. When draining into a central drain deepen the hose 7-10 cm into the hatchotherwise water may spill out.
Make sure that the electric pump does not work “dry”. When its cavity is not filled with liquid, the engine overheats and can burn out.
How to connect a surface pump to a pool? It has 2 hoses. One is immersed in water, not reaching the bottom a few centimeters, the second is used to drain the liquid.
With littered water you can install a small filter at the inlet to the intake pipe. But at the same time, the rate of fluid outflow will greatly decrease, and the time of emptying the reservoir will increase.
Electrical appliance should not work more than 4 hours without a break, large pools are best emptied in parts.
Always monitor the operation of the unit. It may be necessary to clean the intake opening of large debris or manually turn off the pump in case of a malfunction.
Major breakdowns and repairs
Of course, the best way to deal with any malfunctions is preservation of all warranty documents and transporting the pump to a service center. This is especially true when the pump for pumping water out of the pool does not work due to manufacturing defects.
If they are found at the beginning of the unit, require replacement. But if the warranty has passed, you can try to repair or replace parts yourself.
There may be such acquired problems:
- Rotor jamming. Or the water is too hot, which is extremely rare. Then postpone pumping out until late in the evening or even morning. Or large particles of debris get into the rotor, they must be removed.
- Strong vibration. You will need to install the unit on a rubber substrate. If it has been used for a long time, the bearings may have worn out and need to be replaced.
- Flowing along the shaft. Worn packing or mechanical seal, replace it.
- Overheating of bearings. They will need to be lubricated or replaced with new ones if the wear is large.
- Increased power consumption. The seal or impeller may be worn out and a replacement is needed.
- Water is pumped out much more slowly.. The impeller could wear out, check and change.
- Does not turn off automatically. This is a breakdown of the relay, it must be removed and dried well, sometimes replaced.
All breakdowns easier to prevent than to fix. Treat the appliance with care, do not let it work outside the recommended conditions.
Keep an eye on the dryness of the surface pump housing to drain the pool water and the proper installation of the submersible. Check if the intake hole is clogged.
If the noise and vibration levels increase significantly, immediately turn off the unit and determine the cause. Drain the pool water in several stages. With these simple methods, you will achieve the long service life of the selected electric pump.
As you can see, there are not so many types of pumps for pumping water out of the pool and the choice is simple enough. Before buying, select the power of the electric pump and its type based on the volume of pumped liquid. Read reviews about manufacturers and models.
Buy a pump whose service center is available in your city. Clean your cottage pool regularlyDo not allow water to bloom. And your pump will last for many years.
