Why are you needed and how the pumping pumps are arranged?
Pumping pumps may be needed in a variety of everyday situations when it is required to get rid of polluted and even very dirty water. For example, if the basement at home is elevated during floods. The drainage pump will help pump fluid, that is, lift from the depths to the surface and reset to another place. Such a place can be a roadside cuvette, a pond or natural deepening resulting from a linker. If they are located far from the house, to the pump, naturally, you need to connect the discharge hose. This is relatively simple. For the simplest pumps, it is enough to buy an ordinary garden hose of the desired diameter. One end it is put on the exhaust pipe located on the pump lid, the other is displayed in the plum. Pumps having a large diameter nozzle (40-52mm) are completed with special rubberized hoses with couplings at both ends. The connection process is very similar to the preparation for the work of the home vacuum cleaner, and the pump itself looks like a vacuum cleaner.The drainage pump is adapted to work in the condition submerged. Some of the caustic include the device, lowered to the depth, - they say, how is it there in the water? It is not worth worrying at this expense, because manufacturers all have provided and made the electric part of the pump waterproof, reliably isolated. The engine is placed in a sealed internal case, from which only the rotating shaft comes out. The wheel with blades is notated on the shaft. During the operation of the device, water fills the space between the inner and outer hulls, forming a "shirt" of cooling. Thanks to this, the pump does not overheat. Extremely expensive models used another cooling method (the so-called "dry" motor). Such a pump water for cooling is not needed: the engine rotor rotates in a special oil medium, it creates a small coefficient of friction, and therefore small heating.
Another example is the construction of the house. After the rich rains of the trench, the foundation turned out to be flooded. How to dry them? Connecting the hose to the drainage pump and lowering it (pump) into the trench. It is not worth the "dip" ourselves, it is enough to attach a cable to the instrument and carefully omitted to the bottom (for this purpose, a handle or special eyelets are provided on top on the housing).
The situation is very common when the site is located in the lowland and requires constant drainage. The water itself does not leave this place, it needs to be deleted artificially. Bending a pump is irreplaceable. The plastic or concrete well is plugged into the soil of a low location of the site and a drainage pump is installed in it. Manufacturers produce for this purpose already ready-made kit: polyethylene tank with a pump available at the bottom and a discharge pipe. The container is buried in the ground, leaving only the upper edge, and is closed with a lattice for the passage of water. Drena (PVC pipe, polypropylene, asbestos or metal) is laid from the well to the plum place.
No need to look into the well every time to turn on the pump, it works automatically. The compartment includes a special starting device - float. Inside it there are 2contacts and a metal ball. If there is no water, the float is in a horizontal position or lowered down, the contacts are open. As soon as the container is filled and water reaches the required level, the float rises vertically up, the ball falls down and closes the contacts. This turns on the pump.
Examples of using the drainage pump can be given a set. It will help even where it is necessary to raise clean water to a small height. Single drainage pumps pump water into the heating system, in the tank of the summer soul, the ponds and fountains of the non-pressure stream type and even wash the cars, although it is inconvenient (low pressure).
What should pay attention to when choosing a pump?
In stores, pumps that differ in power and sizes are ranked. The consumer enters the difficult position: what device is it necessary for him? To work well, and did not forced to overpay for excess power.
The optimal choice "for the home, for the family" - the pump at 0.65-0.75 kW. Such power is enough to cope with quite large water masses. In addition, other technical specifications are also indicated in the passport, but the consumer first is worth paying attention to the main: water supply rate, or pump performance. It is measured in cubic meters per hour and allows you to determine how long you have to pump out the required amount of water. With the same engine power, this characteristic of pumps from different stamps varies and depends on the design features of the device. To solve the problem of choice, ask yourself: what time of the operation would be arranged for me? By might of us your temperament and the limit of patience. One must, so that everything was done instantly, the other is ready to wait for the empty of the pit for hours. Therefore, when choosing a model, divide the volume of the pits to the pump performance, and you will receive the desired time.
For example, the volume of the basement of the house having a size of 66m in terms of 72m3. In the spring, flood waters flood it on the floor meter. Therefore, it is necessary to pump about 36m3 water. Pump Tor-2 (Pedrollo) with a capacity of 0.37kw and with a capacity of 8.4 m3 / h will make it for 4.3h, the TM pump from Wilo (16m3 / h) - for 2.5 hours, cr from Grundfos (0,35kW, performance 12m3 / h) - for 3 hours. It is necessary to consider that the passport shows the limit values, in reality, the pumping time may increase.
Readers are entitled to ask: Ana what height and horizontal length pump gives water? Water lifting height is indicated in the passport, and the horizontal can always be determined by itself. The dependence is this: 1M lifting is 9-10m the length of the horizontal.
Another important passport characteristic is the maximum size of solid particles transmitted by the pump. Or is it different: for what water is it intended, clean or dirty? If dirty, it is important to know what the diameter of the exhaust pipe. Often, work on the drainage of sites, trenches and ponds is carried out with very dirty water, in which a variety of inclusions may be present: lumps of dirt, stones, silt, chips, plants, etc. It is impossible to prevent them from entering the pump. Therefore, it is better to have a device capable of pumping dirty water with dimensions of mechanical particles up to 40-50mm. Such should be the inner diameter of the nozzle. When pumping relatively clean water, this characteristic can be neglected.
Some additional characteristics of the pump that determine its operational qualities are important for the consumer. For example, whether the device has a float, or it needs to be purchased separately. It is worth paying attention to the presence of a device for protection against an overheating sensor or a thermoster. Structurally, the pump is arranged in such a way that the water passes through it, washing the inner housing in which the engine is concluded. That is, water plays the role of "shirt" cooling. But in practice it happens that this is not enough, because most often the pump is used in emergency situations when they forget about the time. Watchfreight mode of engine overheating, burning out of lubrication and pumping the pump is quite real. Therefore, it is safer to have a thermaller, which automatically turns off the engine in case of overheating.
And be sure to pay attention to the temperature limitations. Pumps can be designed for work or cold, or with warm water. For different brands there are different limit values: up to 35, 40 or 50c.
Features of drainage pumps
The pump "GNOM" produced by the Moscow pumping plant is very popular among homeowners. It has a solid power, equipped with thermal protection (thermostat) from overheating and priced outside of all competition. The largest number of import pumps available in our market is Italian. SPERONI, NOCCI (VIP, BIOX), Marina, Dab, Pentax, Indox, Pedrollo, Lowara and others are abundantly represented in Russian stores. All devices listed manufacturers can safely buy. They are "convenient" for our buyer with prices and good quality. The drainage pump capacity up to 0.4kw is usually about 3000 rubles. The same pump, but with constructive features, significantly improving the engine resource and the overall reliability of the device, are two or more times more expensive. It must be taken into account. What can be constructive features? "Dry" motor (rotor rotation occurs in a special oil bath); Special engine tightness achieved due to multi-level gaskets and an intermediate oil chamber; The use of graphite lubrication and special high-tech materials and alloys that guarantee increased wear resistance. Solid side, the use of drainage pumps "in the economy" is very brief, which allows years to operate the device without lubrication and maintenance. Practice shows that consumers with equal success can burn both simple and complex pumps. This occurs mainly due to improper application.Small pumps Speroni, Dab, Nocci, Pentax, Pedrollo, Lowara are mainly designed for relatively clean water. Used to drain the flooded rooms of small square, to pump wastewater from washbasins, bathtubs, washing and dishwashers. Can be used for irrigation and fountain devices. The housings of these plastic devices, with a suction grid below. Almost everyone in the kit includes floats and power cords.
The pumps of the same manufacturers class are higher, made of stainless steel, can already swing water in half with mud and even apply in sewage systems. It all depends on the diameter of the exhaust pipe. The devices are operating automatically, differ in high power, equipped with thermal protection. From above have a handle for carrying. Such pumps can be used to solve a variety of tasks. Stainless steel housings are made by extrusion, without weld, and therefore more racks to corrosion. Some devices firms Lowara, Nocci, Wilo, Grundfos and even domestic Aquasab4037 are completely made of stainless steel.
The most powerful models of this class have a lower part with a special protrusion and a hole for the vertical exhaust pipe. Such protrusions are, in particular, at the Pedrollo and Wilo models. When installing these products, it will not be necessary to install additional shaped elements. You just need to remove the plug and screw the discharge pipe with the appropriate thread. Pumps with a diameter of a nozzle of 50-65mm are able to roll out anything, including the dung alive and river Il. Can be used in sewer systems. The most frequent use is found when pumping water from construction boilers, draining ponds. The TP40S (Wilo) pump is so expensive because its working part is a patented device, a special cutting nozzle capable of changing everything, even pieces of fabric. Therefore, the device can be applied anywhere, even in sewer systems. All pumps are designed for cold water, but briefly capable of withstanding water heated to 50-60s (Grundfos pumps - up to 70c pumps).
Drainage Pumps
A variety of drainage pumps - drainage-fecal or just fecal pumps. Their appointment is the removal of a large volume of drains from shells, baths, toilet bowls, dishwashers and washing machines. For this, pumps are equipped with more powerful engines. Have a slightly expanded lower part, inside which there are steel blades that can not only pump water, but also chop fibrous inclusions.
Another citizen will ask: "I have this pump to me, if, and so with the drains of any problems?" Ibuly rights. There are no problems in the forefall conditions, they arise when retreat from the standard. For example, if you make redevelopment of the apartment and relate to the toilet further from the house riser. In this case, every excess length of the length of the horizontal discharge pipe threatens to become a place of blockage. Another non-standard option is a basement or basement floor, where the toilet or shower is located below the level of the ground and the sewer highway. Then the stocks need to be raised up. Yves volume and in another case without a fecal pump can not do.
Owners of apartments can come in different ways. For example, separately purchase a suitable pump and connecting elements, and then invite installation professionals so that they do everything. You can proceed in other things: buy a compact finished installation, which is a plastic tank (Potpipa toilet bowl), in which the pump is mounted and there is an outlet for connecting to the removal sewer pipe. Such systems are called dislocation variable bathrooms (SPD). Their main advantage is that the SPD can be located far from the riser (only drain pipes should not pass over the residential premises and the kitchen of the lower apartments). If the SPD is connected to the toilet, it is necessary to consider one feature: the flush will not be instantaneously, as in the usual version for us, and with some delay. Initially, water from the tank will fill the toilet, and only then the pump will turn on. I am a single remark. Pumps in SPD are small, with a small outlet diameter. Therefore, throwing cigarettes and paper into the toilet. It is worth such a bathroom about 21-25 thousand rubles.
In country houses, fecal pumps are used as an integral part of the cleaning facility. The meticulous reader can exclaim again: "Why does he, if everything works for me?" Yes, in most individual, or local, sewage treatment facilities (LOS), stocks fall sick. But it turns out not always. Much depends on the terrain. Wine cases of pipes with drains have to be laid over long distances (up to 40-50m). If the house is located in a lowline or on the slope, and at the bottom of the neighboring sites, the drains will have to be dug away. For such cases, fecal pumps are intended.
Especially often, it is necessary to install them in individual houses of the near Moscow region, where the colossal recurrence, and the pollution of surface waters and the upper layer of the Earth exceeds the permissible limits. The sanitary doctors of the regions adjacent to the capital have long been alarming, and administrations impose restrictions on the use of certain Los. For purified effluents, end structures are needed: soil filtering systems or biodewesters under the control of the SES. Everything is going to the fact that both new and already existing cottage villages will have (or already have) collective use treatment facilities. That is, as in any village abroad, one powerful fecal pump is installed on a collective sewage treatment. Its operation turns out to be more effective, cheaper and helps to keep nature.
When buying a fecal pump, pay special attention to the diameter of the outlet. Optimal dimensions from 65mm. If the pump is still installed with a smaller diameter, the working body must be a wheel with cutting blades. This is a prerequisite, otherwise the system will clog and stop working. Consequently, you must first decide on the choice of the type of treatment facility, and then go to the store.
In addition, it is necessary to remember about one problems. Unas are trying to apply domestic products from PVC or polypropylene. They are racks for corrosion, they differ in good quality and are relatively inexpensive. But the cross section of our pipes and exhaust pipes of import pumps (Avlebi is used precisely there is simply no) not always coincide. Thus, PVC pipes have external diameters 40, 50, 75, 110mm, polypropylene - 40, 50 and 110mm. Therefore, acquiring the pump, you need to immediately buy a signature tube to him immediately, and then in those who will mount the construction, order, if necessary, adapter under your pipes.
At the output of the sewage treatment, the drainage pump can also be mounted. It is necessary if peeled (or gray) water is required to be discharged by several tens of meters. It must be said that the sewage treatment with pumps is much more expensive than the self-sized (almost a quarter).
Installing the pump to the well is thought out by manufacturers to the smallest and does not require special effort. Tricer can not even go down. The process is as follows. Previously, at the bottom, the angular pipe with the discharge pipe and two vertical guides are attached (the inlet plastic container all this is already mounted). The pumps themselves are equipped with special grips. You need to put on the pump with the captures on the guides and with the help of the cable to lower down. Having reached the nozzle, the pump tightly snaps into it and due to its own weight will provide tightness of the compound, so that no wren fasteners will be required. The device will always be lifted to the surface and inspect.
Fecal pumps helps to get rid of headaches and when installing sanitary pribor in basement. Here is possible reverse pressure and flooding basement with drains. The return valve is mounted at the outlet, it is not always enough. Problems with flooding will not arise if using a special compact sewer installation. It is a plastic container by 45-150l, into which one or two fecal pumps are premons. Mounted in the basement or on the basement floor.
Fecal pumps are usually powerful, produced in three-phase design, under voltage 400V. The working body is a wheel with one (single-channel, closed type) or several (multichannel, open) curved blades that are enlarged by liquid, as oars, and promote further.
Some models have protrusions for a vertical outlet pipe at the bottom of the housing. For these pumps, an additional fitting nozzle is required, which is very convenient and frees the buyer from unnecessary trouble. A distinctive feature can be the lower immersion part, made not from cast iron, but from a composite material that is not subject to corrosion. This is characteristic of Wilo pumps. Considering that fecal pumps are installed in blurred structures where explosive gas is accumulated, it is recommended to pay attention to the presence of such a device of the device as explosion protection. If necessary, this protection can be performed under the order.
The design features of pumps that increase their operational qualities are greatly influenced by the price. It refers to the increased tightness, the use of wear-resistant materials for rubbing parts, as well as the lubrication method and the quality of lubricant material (graphite, oil baths in which the engine rotor is placed). This largely decreases the force of friction and heating of the instrument, a smooth move and high efficiency is achieved, the engine resource increases. Such pumps should not be serviced throughout the service life: installed and forgotten.
So, dear readers, we tried to consider the main types and characteristics of pumping pumps. We hope the information provided will help you make the right choice.
