To realize that the teeth are dulled are allowed according to some signs that are revealed during the work:
The mountain stretches and sags , in connection with which the saw road works inaccurately and"brakes"in the sawing. The deal with this chain requires additional efforts.
The sawing action slows down, the productivity falls, you have to spend twice as much time for work.
The visibility of sawdust changes: they become uneven, sharpened, smaller. Cutting through the sharpened saw looks like: monotonous pieces of flat rectangular shape. If the saw loses its fidelity and gets stuck in the cut - it's time to repair the chain teeth.
Do not separate the repair work for a long time. Than in advance sharpen, the less material it is necessary to grind, accordingly, the longer the building time. And do not have to do with dull equipment for a long time, multiply its wear and waste your own physical forces. Two standards of chips: the main - the result of saws with a sharpened saw, the second - blunted
What tools are there for the grind?
For the beginning of the work, you must stock up with tools that are divided into two types.
Hand tools
Assortment of tools ,A small ratfil, which is taught to be used again for school lessons. With it, the depth stopper is grasped .
The cross-cut curve of the rattle, which is necessary for the processing of the cutting tooth. An additional tool is attached to it - a holder with lines that give a clue, like to properly hold the gun in accordance with the chain. The holder is positioned for the saw tooth, taking into account the guiding lines, the place of the ratfil is near the cutting surface.
The custom who serves to edit and observe the characteristics.
The police are needed to divide the chain from the chain.
Sets of various configurations are allowed to be purchased in a special store
Manual and electronic machines
Like pouring a mountain of chainsaw, if the cutting edge of the tooth completely lost its shape due to long-term work? It is permissible to extract and ratfili, however, the action is quite unproductive and time-consuming. A balanced version is the use of machine tools, and here it is necessary to select, because the machines are different - manual and electronic. Light machine for the grinding of chains of the Stihl brand
processing is much faster than with the help of ratfil: for the grinding of each tooth, 2-3 movements are enough. Electronic machines also have a complex set-up, while still working vividly and seemingly. The electronic machine allows you to reduce the amount of time, but not the individual drunk to lay out a round sum because of it.
Main rules and schedule of sharpening
Structure and type of teeth
First, you should orient yourself in the device of the tooth of the chain, who is to be sharpened. Fang cuts the wood as a plane. It has a complex configuration and an unusual cutting appearance - two edges: one of their lateral, and the second - the upper, slightly slanted. The tooth stopper, the height of which changes, adjusts the thickness of the chips. Of course, sharpening such teeth is much more difficult than, for example, a kitchen knife. The chain saw has a more complex shape than other sharp objects that need to be sharpened
In doing so, it is necessary to set a secure grinding angle for chainsaw chains. Of course, it's problematic to fight with one ratfil, therefore there are various auxiliary devices that help to adhere to the precise characteristics of sharpening. Such sets are sold complete with chainsaws, also separately. The diagram shows the angles of inclination that must be performed in the grinding area
The tool position must be correctly selected to be sharpened. Curve ratfil elected not in vain - due to the rounded shape of the inner contour of the tooth. The edge of the ratfil is forced to exist above the cutting surface for 20% through its width, and the length of the chain pitch (usually 4 mm before 5.5 mm) influences the choice of the diameter. It is necessary to execute the schedule of actions: before processing the cutting teeth, then - the tooth-limiter.
Sharpening of cutting teeth
The task appears: how to sharpen the mountain for no reason, so that without teeth the teeth were moderately smooth and sharp? The work is simplified by the use of an iron template, which is imposed for the mountain. It is installed in a serious position - in accordance with the arrows, whose ends are oriented in accordance with the movement of the chain. The main burden is for the preceding margin, with a slope, who is related to the length of the chain pitch.
It is necessary to strive, so that for an individual tooth there would be an equal number of movements. Teeth are sharpened according to the queue: the only one is on the left side, the next one is on the right, and so on. For the convenience of performing the actions, the tire is clamped into the vice, and then processed through a tooth on one side, then without reason. During the grinding process, the tool must be around a certain angle.
Grinding of the limiter
The work is regulated by the custom that the tooth-limiter should no longer grasp before the level, but a flat ratfil. The layout of the"S"template is created for a soft woody species,"H"is for the sake of a hard wood. If you do not use the custom, you are allowed to get the wrong one, the small one has been cut down, through which the efficiency of the saw's work will soon decrease. The protruding portion marked for the photo is being grinded by the limiter

The water pump is the main element of water supply, irrigation, irrigation systems. Through its functionality, the whole system as a whole depends. If the structure is initially selected incorrectly, there is not enough power or the structure of the device is not suitable for the sake of the functions performed, then malfunctions are inevitable. In this case, you will either have to purchase additional devices that compensate for the flaw, or change the sample itself. In order to choose the right water pump for the sake of water for the sake of the house, giving or the garden, the structural features, the mechanism of operation, the task and the technical properties of the water lifting equipment must be taken into account.
General principles of the pump device
A separate type of pump has its own design features, but the universal mechanism of operation for all pumping devices is the only one. To turn on the electric motor inside the case creates a vacuum. Due to low pressure, water is sucked into the vacuum chamber, moves to the outlet nozzle and is pushed through it forcefully into the hose or pipeline. The force of"squeezing out"the water determines the burden in the system. It must exist rather high to overcome the hydraulic resistance. All the pumps operate in accordance with the principle of drawing water through the inlet hole and ejection through the outlet pipe, they differ only by the method of vacuum creation
Pump designs can vary considerably depending on how the vacuum is created in the device, according to this feature, the pumps are divided into:
centrifugal
vortex
vibratory (the 2nd name is electrical).
Depending on the position of the pump relative to the water tank, surface and submersible models are distinguished. In accordance with the design and functionality of the device is divided into well, borehole, drainage, motor pumps. A more detailed explanation of the fate in the video clip below:
All the elements of construction are made of durable materials, the parts do not actually wear out. It is understood that the pumps will do continuously. Therefore, they are developed without reason, so that the service was easy and quick. Devices can make large temperatures in chemically brutal environments, properties depend on the characteristics of a particular model. Some of them stand up to 350 degrees.
The advantages of centrifugal pumps include reliability, longevity, reliability, acceptable cost, the ability to equip the necessary automation, high efficiency. All, like and any other devices, pumps of this type have their own shortcomings. For no reason, to start the device, the body must be filled with water, because because of the small centrifugal force the water is not sucked into the branch pipe. To be able to get air into the inlet pipe, the pump can brake. In addition, if the opposition in power is changed, it can be seen for the stability of the device. Surface centrifugal pumps are mobile, free to be dismantled and transported, but for permanent installation fit poorly
Extensive distribution of centrifugal cantilever pumps. They are used for pumping clean and dirty water containing impurities and small solid particles. For the systems of water supply of houses and dachas use single-stage horizontal cantilever pumps. Multistage horizontal pumps are a design that works like fairly similar, serially connected, single-stage devices. Due to this they are able to provide a strong foray into the system.
Centrifugal water pumps are received for the sake of the house, cottages, irrigation systems and irrigation. They are installed in water supply systems working through wells. They use submersible and semi-submersible models. The first is easier to install, and the second is easier to maintain. For the installation of a semi-submersible model, special conditions are necessary in the well. This is a labor-intensive affair, therefore, despite the trivial advantages, owners of private homes often stop the election for submersible models. They can be mounted in wells, where the installation of the casing pipe was different through the vertical. To the design deficiencies should be attributed the higher flair for sand and pollution.
We offer a review of centrifugal monoblock water pumps, which are suitable for the sake of the garden:
Особенности работы конструкций вихревого типа
Строение работает из за счет вихревого колеса, представляющего из себя железный диск с лопастями, создающими центробежную силу. В силу конструкционных особенностей вода закручивается в спирали, сообразно виду напоминающие ветер. Суть вес насосов вихревого типа – сильный набег. Быть равных с центробежным насосом габаритах, весе, размерах колеса и количестве оборотов вихревой обеспечивает более здоровый набег. Следовательно размеры корпуса вихревой модели могут существовать значительно меньше, чем центробежной.
Thanks to the high pressure created by the vortex pumps, they are used with success for the sake of watering the gardens, orchards. They are excellent for installation in water supply systems for cottages and private homes, if there is a need for increased pressure in the net. In a reward through centrifugal models, the vortex normally tolerate the entry of large air bubbles into the pipeline. Small dimensions expand the scope of introduction of pumps of this type. Out of the flaws is a flair for the suspended particles in the water. If they are abundant, the pump should be done with interruptions and quickly become unusable. Thanks to its small size and high power, the vortex pumps are great for installation in deep wells of small diameter
Vibration pumps for home and garden
For the sake of the house, cottage and garden, it is allowed to elect an electronic water pump of vibration type. The view of his work is based on the effect of an electric field created by a coil that draws in an iron core with a flexible diaphragm. Bending, the rubber diaphragm makes a low burden by which water is sucked into the hydraulic chamber. If the diaphragm returns for a room, the burden increases and the valve closing the inlet hole works, so water is pushed out through the outlet pipe. Constant motion of the diaphragm ensures uninterrupted pumping of water.
Vibration pumps are used for the organization of irrigation and irrigation of plants. They are installed in systems of autonomous water supply. A great advantage of this design is the gift of pumping dirty water, which allows using them to pump wells and wells for the sake of preventive cleaning. To be able to work with dirty water, the performance of vibrating pumps drops noticeably, they are all controlled with the cleaning of the bottom of hydraulic structures. Another plus of the design is a relatively low dignity and reliability. The longevity of the devices is provided by the design, to which some moving, rubbing parts. If the diameter of the borehole is relatively large, it is permissible to install a vibrating pump, having rubber rings for it in advance for the sake of"killing"the vibration <
The disadvantages of electronic vibrating pumps are not less than pluses. In the operation of devices, failures occur frequently in the event of voltage drops in the power grid. If the owner of the house decides to install a vibrating pump, the exact voltage regulator should be purchased. Such pumps are used for the sake of pumping water from wells, but they do not need to be installed in wells, mainly of small diameter, despite the comfort of installation. Constant vibration does not have a good effect on casing design, and at some point the pump either breaks down in person or destroys the production pipe. The trickle pump does not need to be mounted in narrow casing. This can result in an unplanned pump repair or even drilling a new well
Application of surface and submersible pumps
The water-lifting environment can be divided for surface and submerged. Pumps of the first type are installed near hydraulic structures or water bodies, from which the city of water is being built. The second is lowered into the water. The designs differ in accordance with the performance, type and location of the inlet nozzles that are acceptable for installation conditions. Surface models are usually cheaper and able to do if the water layer is below 80 cm. Submersible pumps should be made for a depth of more than 1 m near the surface of the water.
Surface Models - Good Election for Watering
A surface water pump for the sake of a garden or vegetable garden is the best option if it is necessary to organize watering from a natural reservoir or a large reservoir. As necessary, it can be easily dismantled and moved to another room, removed for storage. It is great for dachas. This pump can be installed for the sake of taking water from a well or a shallow borehole (before 9 m), an Abyssinian well. In this case, the owner does not have to choose the structure according to the width, because The hose is lowered into the well, and the pump is installed close to the production pipe. Pumping stations are referred to as surface water-lifting equipment. They are functional systems that combine a pump and a hydraulic accumulator
An unparalleled aspect - for the sake of mounting a surface model it is necessary to prepare a place where the structure is fairly protected through water, and voices through its works are not enough to move anyone. Set the range either for the ground, or for a special floating platform, if you need to store water from an open source. To be mounted in unsealed closed pits, the bottom is not poured with concrete, but covered with gravel. Bulk materials absorb excess water that may seem to be water seeping through seams of concrete rings or brickwork.
It is necessary to keep the calculation of suitable power in mind, which is analogous to the length, in accordance with the vertical and horizontal, equal to 1: 4, i.е. 1 m of vertical pipeline is considered as 4 m horizontal. For the organization of water supply, it is better to extract plastic pipes, rather than rubber hoses. During the pumping of water according to flexible hoses they can be compressed and bent through pressure drops. Water is not quite normal to break through a narrow hole, which will lead to interruptions in the flow. With the help of surface equipment, it is easy to arrange watering of plants from the pond. For the sake of this, the choice of the model should take into account the fact that the water is pretty much done with particles of dirt and sand.
Submersible environment for the supply of water at home
The chosen pump for the sake of water for the sake of a house or cottage, where they live for a long time, is submersible. It is excellent if you plan to install a water supply system through the deepest well (above 9-10 m). An ordinary household sample raises water from a well deep in front of 40 m, and for the sake of deeper structures it is permissible to find a structure more powerful. With the selection of pumps for the sake of wells in front of 80 m sometimes there are problems; the collection is wide. Without submerged submersible models are equipped with automatic protection through"dry running."
Install submersible pump is allowed, if it does not touch the bottom quite enough, and the height of the water layer above it is more than 1 m. This should be for several reasons. Firstly, in order for the engine to cool normally, there must be a sufficient number of water. Secondly, the height of the water in the well or the well is not stable. It can vary depending on the season. Proudly, so that the pump is not extremely close to the mirror of water, if there may be difficulties with water supply. The pump is not forced to reach the bottom for 2-6 m, so that the puddles and grains of sand from the bottom do not get into the inlet pipe. Distinctive exclusion of drainage pumps - the gift of pumping like clean water, uncaused and stained with hard inclusions. For the inlet branch of the pump there is a grid. Devices are allowed to be connected to water supply systems
Short video tutorial according to the choice of pump
When choosing an electronic water pump for the sake of a house, cottage or garden, first consider its target. Perfect equipment"for everything"does not exist. Smudge, what are the main tasks enough to execute the building, is it enough to do it only to pump clean water or to eat the opportunity that he will have to raise water with sand and muddy.
