Why not just there in the sewage: grease, dirt, sand, biological waste, etc.And that the pipe taking the brunt of the load transported by them dirty media.Theoretically, all the sewer lines are laid with the expectation of their self-purification, that is, calculate the flow rate of wastewater, create the desired angle of inclination of pipes, think especially sewage system turns.However, in practice, even with all the technical requirements for operation, the tube walls accumulate various deposits.Most often, these mud-fat build-up in pipes occur due to several reasons:

  • violation slope of sewer pipes;
  • pipes entering the cavity of objects not transported by the flow of water;
  • violation hydraulic conditions in the sewer system;
  • too long use of sewage without periodic cleaning.

due to build-up the inner diameter of the pipe is gradually reduced.The more deposits in the pipe, the more intense is the process of increase of the mud layer, the greater the likelihood of a full exit pipe failure (obstruction, rot).But the most dangerous - is the accumulation of dangerous gases in the cavity of the pipeline, which adversely affect the material of construction of the pipe and can be dangerous for people.

To eliminate the need to completely dismantle the damaged pipe and replace them with new ones, should regularly conduct preventive sewer cleaning.For this purpose, there are special machines hydrodynamic flushing of sewer systems, divided into two types:

  • mounted on trucks and used exclusively for washing external communications;

  • portable small-sized units are transported in cars and used for flushing sanitation inside the home (including those used in apartment buildings).

  • Hydrodynamic cleanout machines of the second type are used for cleaning pipes with diameters from 20 to 150 - 200 mm: cold and hot water supply, heating, sewerage, drain pipes, drains and sinks,channels, etc.
    After the pipe of the washing procedure a long time back to a working state, fully compliant with the specifications.

Hydrodynamic machines used for other purposes in hospitals, schools, catering establishments, homes, etc.The use of machines for washing sewage allows completely remove growths from the pipeline walls, sludge, sand, silt, dirt, scum, grease, solids, oil, traces of concrete, oil, grout, and even ice jams in the frozen pipes.

Options hydrodynamic machines for washing sewage

Depending on the manufacturer, the machine model and its value can vary and equipment .However, none of the hydrotreating unit is not available for sale without:

  • powerful motor and pump;
  • water tank;
  • long hose wound on the drum;
  • nozzles for pipe cleaning with pressurized water.

additional units are equipped with life can : high-pressure gun, tool for cleaning nozzles, metal frames with wheels for the transportation of cars, different devices and operating pressure regulators, filters, packing briefcase.

Nozzles for hydrodynamic cleaning

nozzles - the main working tool of hydrodynamic machines.For each case selected a certain nozzle, given the size of the pipe, the degree of contamination and the nature of the existing blockage.Nozzles are different in appearance, size and destination.There are special nozzle for removing fat deposits, roots, grease, penetration of difficult chronic blockages of the pipeline bends, turbo nozzle, jet, rotating, chain, bottom, etc.

Hydrotreating internal and external sewage, differences

Under domestic sewage understand pipes laid directly from the plumbing and to the first chamber septic tank / sewage pit.When cleaning these pipes are used not only water, but also a reagent solution for better plaque removal of fat, PAV.

Under outdoor sewerage pipes understand, coming from manholes to the central sewerage.This treatment is carried out in steps.Pipe sections were washed under pressure, after which the waste pump is pumped liquid.Clean outdoor sewerage produce one or two machines (the first - the clean, and the second - for pumping effluent and sludge).Typically, the outer tube has a large diameter sewer and accordingly, a significant amount of fat.

description of the process of hydrodynamic flushing sewage

The process of hydrodynamic sewer cleaning is as follows: under the pressure of 300 atmospheres through a hose with a nozzle into the pipe supplied water pressure, "cut" all pollution.

nozzles have multiple openings facing in different directions (forward and opposite directions) at an angle of 15 to 45 degrees with respect to the axis.

Driving flushing sewage

scheme flushing sewage

Hydrodynamic machine include a network, and then the hose is lowered into the cesspit and a button / pedal lead car in action.At this point, the pump starts pumping water through the hose, which as required is unwound from the reel.Reactive force makes planted move forward with the sewer is rinsed with powerful jets of water.

When necessary pipe section washed, set in motion the drive drum and the hose is wound back.

units hydrodynamic flushing sewage is very maneuverable and highly efficient.

Advantages of hydrodynamic machines for washing sewage

There are several kinds of purifying sewage - from manual (vantus, cable, etc.) to the mechanical and chemical.In this hydrodynamic method of use it has several advantages.The pipes are cleared of all existing deposits very high quality

  2. process does not take much time.
  3. When using hydrodynamic pipe machine (including plastic) are not damaged due to the mild influence.
  4. Hydrodynamic machines are highly effective even in complex configurations pipelines.
  5. Hydrodynamic cleaning is carried out at any temperature outside, including in sub-zero rates.
  6. When the machine does not form dirt and dust do not cause any harm to the environment.
  7. After hydrodynamic sewer cleaning machine in the pipeline is reduced self-purification capacity and significantly reduced the risk of recurrent blockages. \

financial side

sewer cleaning is performed once to several times a year.Many believe that the flushing of pipes - very expensive pleasure, without taking into account the cost of complete replacement of dilapidated sewer pipes clogged, which is significantly shake the budget of any family or organization.

For cleaning you can hire a team of workers to clean out the car, to take a similar car to lease or purchase a portable hydrodynamic machine for personal use.At the same time the price tag for cleaning workers pipeline starts from 250 rubles per meter of pipe.The final amount is usually calculated on the basis not only of the length of the sewage system, but also because of the complexity of pollution / blockage.

personal portable unit can be purchased a minimum of 125 thousand rubles (for example, US domestic production or plant Arzamas).Quality equipped vehicle hydrodynamic flushing would cost about five hundred dollars ( "Kёrher" or "Rotenberg").

Hydrodynamic sewer flushing fully justifies the financial costs, since long delays necessary to replace sewer lines, extending their life.
