Hydrodynamic sewer cleaning machine - overview

Hydrodynamic sewer cleaning machine

There is nothing to be found in sewage: grease, dirt, sand, biological waste, etc. And it is the pipes that take on the main load from the sewage transported along them. Theoretically, all sewer pipelines are laid with the expectation of their independent cleaning, that is, calculate the flow rate of the effluent, create the required angle of slope of the pipes, consider the features of the turns of the sewage system. However, in practice, even when all the technical requirements for operation are met, various deposits accumulate on the walls of the pipes. Most often, similar mud-fat growths in the pipes arise for several reasons:

• violation of the slope of sewer pipes;
• penetration into the cavity of pipes of objects that are not transported by the flow of water;
• violation of hydraulic conditions in the sewage system;
• too prolonged use of sewerage without periodic cleaning.

Because of the build-up, the inner diameter of the pipes is gradually reduced. And the more deposits in the pipe, the more intensively the process of increasing the layer of dirt, the greater the probability of a complete pipe failure( blockage, decay).But the most dangerous is the accumulation of hazardous gases in the cavity of the pipeline, which adversely affect the material from which the pipe is made, and can also pose a danger to people.

To get rid of the need to completely dismantle damaged pipes and change them to new ones, regular preventive cleaning of the sewage system should be carried out regularly. For this purpose there are special hydrodynamic washing machines for sewage systems, are divided into two types:

• installed in trucks and used exclusively for washing external communications;

• portable small-sized units, transported on passenger cars and used for washing sewage systems inside the house( including those used in multi-apartment buildings).

• Hydrodynamic cleaning machines of the second type are used for cleaning pipelines with a diameter from 20 to 150 - 200 mm: systems of cold and hot water supply, heating systems, sewerage, drain pipes, drains and drains, channels, etc.
  After the flushing procedure, the pipes will return permanently to a working condition that fully meets the technical requirements.

The result of flushing the pipes with the

hydrodynamic machine. Hydrodynamic machines are used for their intended purpose in hospitals, schools, catering establishments, residential buildings, etc. The use of sewage washing machines allows completely to remove from the walls of the pipeline build-up, sludge, sand, silt, mud, scale, fat, solid inclusions, fuel oil, traces of concrete, fuel oil, grout and even ice cork in frozen pipes.

Completion of hydrodynamic sewer cleaning machines

Depending on the manufacturer, the model of the unit and its cost, the configuration may also vary. However, no hydrotreater is available for sale without:

• powerful engine and pump;
• water tank;
• of long hoses wound on a drum;
• nozzle for cleaning pipes with water under pressure.

In addition, the units can be equipped with : high-pressure gun, tool for cleaning nozzles, metal frames with wheels for transporting the machine, various instruments and operating pressure regulators, filters, packing case.

Variety of nozzles for hydrodynamic machine

Nozzles for hydrodynamic cleaning

Nozzles are the main working tool of a hydrodynamic machine. For each specific case, a certain nozzle is selected, taking into account the size of the pipeline, the degree of its contamination and the nature of the existing blockage. The nozzles differ in appearance, size and purpose. There are special nozzles for removing fat deposits, roots, fat, punching difficult old clogs, passing the bends of the pipeline, turbo nozzles, jet, rotating, chain, bottom, etc.

Hydraulic cleaning of internal and external sewerage, differences

Under internal sewerage is understood as pipes laid directly from the sanitary ware and up to the first compartment of the septic tank / well of the sewage system. When cleaning these pipelines, not only water is used, but also reagent solutions for better removal of fatty deposits, PAV.

Internal water drainage by hydrodynamic machine

Under , the external sewage system is understood as the pipes coming from the inspection wells to the central sewer. Cleaning is carried out step by step. The pipe sections are rinsed under pressure, and then the used liquid is pumped out by the pump. Cleaning of the external sewerage is made by one or even two machines( the first is cleaning, the second - for pumping out drains and sludge).Typically, the pipes of external sewage have a large diameter and, accordingly, a significant amount of deposits.

Hydrodynamic sewerage cleaning

Description of hydrodynamic washer cleaning process

The very process of hydrodynamic sewage cleaning is as follows: under pressure up to 300 atmospheres, through a hose with a nozzle, a water pressure is applied to the pipeline, which "cuts off" all impurities.

Nozzles have several holes facing in opposite directions( in the forward and opposite directions) at an angle of 15 to 45 degrees with respect to the axis.

Sewer cleaning scheme

The hydrodynamic machine is connected to the network, after which the hose is lowered into the sewer and the button / pedal drives the machine. At this point, the pump starts to pump water through the hose, which, as necessary, is unwound from the drum. The reactive force causes the ramp to move forward, while the sewage is flushed with powerful jets of water.

Purging the pipes with the

hydrodynamic machine When the required pipe section is flushed, the drum drive is started and the hose is pulled back.

Units of hydrodynamic washing of sewerage are very maneuverable and highly efficient.

Advantages of hydrodynamic sewage cleaning machines

There are several types of sewer cleaning - from manual( cable, cable, etc.) to mechanical and chemical. In this case, the hydrodynamic method has several advantages of use.

Nozzle of hydrodynamic machine in action

1. Pipes are cleaned from all available deposits very qualitatively.
2. The process does not take much time.
3. When using a hydrodynamic machine, pipes( including plastic ones) are not damaged due to soft impact.
4. Hydrodynamic machines are highly effective even in pipelines of complex configuration.
5. Hydrodynamic cleaning is performed at any air temperature, including at minus values.
6. The machine does not generate dirt and dust, no harm is done to the environment.
7. After cleaning the sewage system with a hydrodynamic machine in the pipeline, the self-cleaning ability is restored and the risk of repeated blockages is significantly reduced. \

Financial side of the

issue Sewer cleaning is performed one to several times per year. Many believe that flushing the pipes is a very expensive pleasure, without taking into account the cost of a complete replacement of the worn out sewer pipelines that would significantly shake the budget of any family or even an organization.

For cleaning, you can hire a team of workers with a cleaning machine, rent a similar machine or purchase a portable hydrodynamic machine for personal use. In this case, the price tag for cleaning the main pipeline workers starts at 250 rubles per meter of pipe. The final amount is usually calculated not only from the length of the sewage system, but also from the complexity of the contamination / blockages.

Personal portable installation can be purchased for at least 125 thousand rubles( for example, the US production or the domestic Arzamas plant).A quality fully equipped hydrodynamic washing machine will cost about five hundred dollars( "Körher" or "Rothenberg").

Hydrodynamic wastewater washout fully justifies the financial costs, as it permanently postpones the need to replace the sewage pipelines, prolonging their service life.
