How to choose a pumping station for a dacha water supply system

How to choose a pumping station for a dacha water supply systemThe pledge of a suburban home by the water supply system has become a necessary condition for a comfortable life. If for a site to eat own aperture or a well, the pump station for the sake of a summer residence is the reasonable and effective decision. Its presence is a mortgage of supplying water in the right amount to every home point of water extraction. In order to choose a more balanced version of the unit for your own home, you should familiarize yourself with its device and the mechanism of operation.
The structure and the task of the unit
For a suburban area, household pumping stations are used for the sole purpose of providing the residential building and the surrounding area with water from sources of any kind: artificial (well, hole) or natural (river, pond). Water is supplied either to special storage tanks, for example, for watering beds or garden trees, or steadily to the usual points of draw-off - faucets, mixers, toilets, gas stoves, washing machines.

Устройства с выносным эжектором
Ради скважин и колодцев, зеркало воды которых размещено ниже отметки 9 метров (и перед 45 м), подходят водяные насосные станции, снаряженные устройствами с выносными эжекторами. Малый поперечник скважины – 100 мм. Соединительными элементами являются две трубы.Насосная станция Aquario ADP-255A, оборудованная поверхностным насосом с выносным эжекторомInstallations of this type require mostly painstaking installation, as well as careful business: water with an excessive content of impurities or breakage of the mesh filter provokes blockage and equipment failure. However, they have one advantage - they are advised to install, if the pumping station is away through the wells, imagine, in a boiler room or in an additional outbuilding near the house. For the protection of the pumping station, it is installed in the back room or heated space for the area of ​​the house
Some properties of the pump - longevity, noise height, value, stability - depend on the material of its hull, who happens to be:
iron - stainless steel looks great, keeps the characteristics of water in a constant form, but it has the highest noise level, moreover, the dignity of such a device is higher;
metallic - cheers a moderate level of noise; an unprecedented minus - the possibility of rust formation, hence the choice should be paid respect for the presence of a layer of protection;
plastic - pluses: low noise, lack of rust in water, cheap dignity; a flaw is the shortest possible building time than a metal case.
The plan for installing a pumping station equipped with a surface pump with an external ejector
Избрание гидропневматического бака
Making the rating of pumping stations for the sake of his dacha, one should keep in mind the relative volume of the expansion tank, who does fairly important functions. It helps to regulate the burden in the aqueduct. The number of water in the system will decrease, the amount of water in the system will decrease, the burden will fall, and if it reaches the bottom mark (almost 1.5 bar), the pump will automatically turn on and begin replenishing the water supply. This is quite a result before the time when the burden does not normalize (it will reach the mark of 3 bars). The relay reacts to stabilize the pressure and turns off the pump.
In private houses, the size of the expansion tanks for pumping stations depends on the amount of water used in the system. The more water consumption - the greater the value of the tank. If the tank has a content value, and the water is turned on occasionally, the pump is also quite often used sometimes. Large tanks also use as storage tanks for the sake of water during the time of power outages. More models are needed with parameters of 18-50 liters. A small value is needed if only one person lives for the dacha, and probable points of draw-off are located in the bathroom (toilet, shower) and for the kitchen (tap).
Electric dominance: double defense
Do you want to eat in the installation of equipment with electrical control? In order to answer for this task, it is necessary to discern the advantages of similar stations. The electrically operated pump station ESPA TECNOPRES has an additional stage of protection
Functions that are controlled by the electrical unit:
prevention of"dry running"- if in the well water height falls, the pump stops automatically;
the pump responds to the operation of the draw-off points - cuts or turns off
the pump operation indication
The right can be a gradual change in the speed of the electric motor, which is made by means of an electrical speed converter. Thanks to this function, the water supply system does not suffer from hydraulic shocks, and there is a frugality of electric power.
An unprecedented minus of models with electric control is the highest dignity, hence this situation is not available to many gardeners.
Previous topics, such as the right to elect a pumping station should be carefully learn the technical properties of the pump, expansion tank, the conditions of installation - and then order water quite regularly do and excellent . ak to choose a hacksaw: looking for the best handsaw for woodIn the arsenal of the home master there is always a multifunctional and comfortable in operation disk electric saw. However, there are situations, if you want to cut off the detail and perform a short amount of work according to the tree, and deploy and connect the unit with no time or desire. In these cases, the hand hacksaw is an excellent help. However, it seems like to choose a hand hacksaw in accordance with the tree, so that it is comfortable in the work and easily"gnawed"any species of tree species, we will examine more carefully.
Technical properties of the tool
The saw is legally considered the ancestor of a huge family of hand tools. Since the creation of the first type of sawmill from iron, the saw has endured a surplus of configurations, having managed to obtain numerous"sisters"capable of performing 10 works. In the household it is impossible to be without"toothy assistants": they are not subject to pruning the garden, small carpentry and carpentry
Hand saws according to wood differ among themselves according to many characteristics: the size of the blade, the steel grade, the shape of the teeth, the design of the handle. Let's stop for each parameter more carefully.
Like there should be a hacksaw road?
The main part of the tool is the hacksaw. The 1st, for which it is worth paying attention to the choice of the product - the length of the canvas. Through this parameter, the ability to implement it almost entirely depends. At the same time, the longer the road, the more it springs, which also complicates the action mainly to work with hard wood species, such as ash, maple or oak. Длиннющий хождение дает мочь быть распиловке прибавлять меньше усилий, так как из за единственный хождение рез производится огромным количеством зубьевFor the sake of sawing small parts like skirting boards, brusks or narrow racks, it is possible to do with a hacksaw with a length of the blade of 25-30 cm. When planning to use the gun to perform more severe construction work, choose work with a canvas of 45-50 cm.
Usually the width of the fabric of the product varies in the range of 10-20 cm. Models with a narrower web are not allowed for technical reasons, since they fail to be the smallest coiled one. However, it should be taken into account that extremely wide canvases are inconvenient for the sake of easy work. An important meaning is played by the fabric of the canvas production, in which the alloy steel, in most cases, the alloyed steel, also its quenching stage
For tool blades used tool alloy steel with the highest content of silicon and carbon grades:
65G, 60 C2A;
8 HF, 9 HF, 9 HS; li>U7, U7A, U8, U8A, U8G, U8GA, U9A, U10
metal Tempering is performed due to the impact of the alternating magnetic field to it, to be that the electron current is highest frequency occurs . Propagating in accordance with the surface, it heats the surface discharge of the metal, who then becomes cooler.
The standard parameter is the fidelity of metal in 45 HRC, but still it is better to choose products whose fidelity is 55-60 HRC. Hacksaw with a blade of the highest hardness is enough to own a sufficient elasticity, but with the highest stability of the teeth. To be an external inspection of such a tool can be found according to the darkish color of the sharpened teeth.
The characteristics of the teeth for the canvas
The value of the teeth is the determining indicator of the productivity of the tool and the accuracy of sawing. The teeth of the hacksaw for the sake of work in accordance with the tree do a double function: they cut the tree species and, at the same time, divert the part
Between these technical parameters, there is a reverse captivity:
canvases with large teeth set the highest speed of work, but the sleeves are rough and sloppy;
hacksaws with small teeth ensure a clean and precise cut, but be relatively low speed.
Be determined by the size of the teeth being treated. For example, for the sake of working with chipboard, where the highest fidelity of the cut is required, choose a tool with the highest TPI rating of 7-9, but for sawing logs and garden work, where the cleanliness of the cut is not irrelevant - TPI 3-6. To choose a rational variant of the hacksaw, follow the rule that a small log thickness must exist in any case more than a step of 3 teeth. If we compare the calf and ordinary fang, the difference is that in The first option to be a condition of domestic implementation work is not endlessly blunt. However, a hacksaw with a hardened tooth can not be honed again. If it is bad enough to scold, it will have to be thrown out.
Ordinary canine can be sharpened. Sometimes it is allowed to perform it with the help of a special ratfil, which has the marking of an accident (for the sake of drifting saws). In order to sharpen the road, it is enough to perform fairly movements according to each tooth.
For the sake of longitudinal sawing. Products are equipped with teeth in the form of an oblique triangle and are similar to the outside for hooks. The tool makes it possible to perform sawing of wood species along the fibers. Such saws are sharpened from the 2 sides of the tooth, so they can cut the future, for no reason and in the opposite direction.
For the cross cutting. The teeth of the tools are in the form of isosceles triangles. A similar structure allows one to freely separate matter, such as the future cutting edge, for no reason and in the opposite direction. However, this type of tooth is suitable just for the sake of working with dry billets, but not the freshest tree species.
For mixed sawing. Products have a combined amount, in which triangular edges are mixed with slightly elongated semicircular notches. Such a verdict allows you to move the hands of the future semicircular teeth to execute a guiding cut, and to be returned - triangular to open the channel, taking out the chips and part. Some types of modern tools are equipped with teeth that are made in the form trapezium. Such a verdict makes it possible to execute the road more robust and wear-resistant.
However, it should be taken into account that it is very problematic to sharpen such a road, since trapezoidal teeth are difficult to give the desired shape. This greatly reduces the time the building of the product, For the cutting of the new branches more convenient to use cloth, gear triangular teeth treated with parallel sharpened to be a separate element imprisoned tokmo on one side and staggered
Most of the market is allowed to meet and modernized the appearance of saber. Modernized hacksaws can be easily distinguished according to the teeth arranged for the canvas band, between which the gaps are perfectly visible.
Hand-saws of the modernized type are effective for cutting wet woods s. Wet firewood through the intervals between the teeth in the process of cutting freely out of the cut, without hindering the progress of the tool.
Future hand-saws in accordance with the tree
Drinks a narrow saw is a design that consists of a straight flat blade and a handle. It is made by delicate work: through cuts, cut out curvilinear details. This kind of tool is designed for cutting woody workpieces, the thickness of which does not exceed 8-10 cm, drank small branches and small works in the garden
Manufacturers establish the manufacture of narrow models with curved triangular toothing teeth, or with parallel sharpening. The downside of the tool is that the road can be deflected in the given direction when the road is being operated.
Variation #2 - ordinary
A standard hand saw can be armed with at least some type of teeth and is often equipped with interchangeable cloths of different types and designs. In order to be able to saw off workpieces at a certain angle with a standard light saw it is necessary to get special stools div>However, despite the declared universality of their implementation, the saws of this tia are not the desire to extract furniture.
Variation #3 - with a shoe
Like a narrow, Unreasonably and ordinary saws increase the rigidity of the material being processed la are prone to coils. In these cases, it's great to use canvasses equipped with shoes, who act as a kind of stiffener. Hand hacksaws equipped with shoe are designed to make shallow cuts in the wood surface of all thicknesses
The presence of a shoe does not allow the saw to operate a depth cut more if the blade width, since it prevents the cutting blade from moving further into the tree .
Variation #4 - bows
The beam type is more massive device, which acts as an analog of the jigsaw. The main fate of this type of saw is the product of a clear cut To work with surfaces located about any angle
Due to the thoroughness of the construction and the threaded connections of the handles, the saw type can easily overcome knots,Depending on the purpose and design of the saw, there may be:
large-scale - for the sake of slitting;
transverse - for cutting saws across the wood fiber
for the cutting of openings, for rounding and for sawing,
spike - for the sake of cutting out the connecting studs, also sawing for the preparation of ordinary geometric figures.

Tokmo hacksaw of the beam type is allowed to cut the matter up and down,Tips for choosing a tool
The order of things, like choosing a hand hacksaw according to the tree, is quite simple:
