Hydrodynamic sewer cleaning machine

There's just so much to be found in sewage: grease, dirt, sand, biological waste, etc. And it is the pipes that bear the main load from the sewage transported through them. Theoretically, all sewer pipelines are laid with the expectation of self-cleaning, that is, the flow rate of wastewater is calculated, the required angle of inclination of the pipes is created, and the peculiarities of the turns of the sewerage system are thought out. However, in practice, even if all technical operating requirements are met, various deposits accumulate on the pipe walls. Most often, such dirt and grease build-ups in pipes occur for several reasons:

• violation of the slope of sewer pipes;
• the entry into the pipe cavity of objects that are not transported by the flow of water;
• violation of the hydraulic regime in the sewerage system;
• Excessive use of sewerage without periodic cleaning.

Due to build-up, the internal diameter of the pipes is gradually reduced. And the more deposits there are in the pipe, the more intense the process of growth of a layer of dirt occurs, the greater the likelihood of complete failure of the pipe (clogging, rotting). But the most dangerous thing is the accumulation of dangerous gases in the cavity of the pipeline, which negatively 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 replace them with new ones, you should regularly carry out preventive cleaning of the sewer system. For this purpose, there are special hydrodynamic machines for flushing sewer systems, divided into two types:

• installed on trucks and used exclusively for flushing external communications;

  
  Hydrodynamic cleaning machine

• portable small-sized units transported in cars and used for flushing sewage systems inside the house (including used in apartment buildings).

• Hydrodynamic cleaning machines of the second type are used for cleaning pipelines with a diameter of 20 to 150 - 200 mm: cold and hot water supply systems, heating systems, sewers, drainpipes, drains and drains, channels, etc.
  

  After the washing procedure, the pipes return to working condition for a long time, fully complying with technical requirements.

The result of washing pipes with a hydrodynamic machine

Hydrodynamic machines are used for their intended purpose in hospitals, schools, catering establishments, residential buildings, etc. The use of sewer flushing machines allows you to completely remove build-up, sludge, sand, silt, dirt, scale, grease, solid inclusions, fuel oil, traces of concrete, fuel oil, grout and even ice plugs in frozen pipes from the walls of the pipeline.

Complete set of hydrodynamic sewer cleaning machines

Depending on the manufacturer, model of the unit and its cost, the equipment . However, no hydrotreating apparatus goes on sale without:

• powerful motor and pump;
• water tank;
• long hoses wound on a drum;
• nozzles for cleaning pipes with pressurized water.

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

The main signs of a clogged system

It is quite easy to understand that your drain is clogged. It is worth paying attention to the following signs:

1. Used water does not go away immediately, but accumulates in the washbasin or sink.
2. If plumbing equipment is not used for a long time, an unpleasant odor appears from the system. This indicates that organic deposits begin to decompose on its walls.
3. If you turn on the tap on the second floor of a private house, dirty water will appear in the sink on the first floor. The reason for this is the difference in pressure.

If at least one of the signs is detected, you should urgently take measures to clean the sewer. Otherwise, the sewer system may be completely paralyzed, and it will be impossible to live in the house comfortably.

Operating principle

This type of equipment operates as follows: a rotating cable equipped with special nozzles is placed into the sewer pipe that needs cleaning. As a result, the formations that led to the formation of the blockage are crushed.

The devices can operate in other ways. So, if hydrodynamic machines are used, then a hose is placed in the sewer pipe, from which water is supplied under high pressure into the hose. It breaks through accumulated elements and removes blockages.

Scope of use

There are many simple ways to tidy up your pipes. From time immemorial, the plunger was considered the cheapest and most widespread. Many resort to using a metal cable and various chemicals. But all this helps if the blockage is minor. However, structures can not only become clogged, but also overgrow inside. A coating of rust and lime appears. The water flows poorly or does not move at all. Then you should pay attention to special sewer cleaning machines.

Financial side of the issue

Sewer cleaning is performed from one to several times a year. Many people believe that flushing pipes is a very expensive pleasure, without taking into account the cost of completely replacing clogged sewer pipelines that have become unusable, which will significantly undermine the budget of any family or even 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. At the same time, the price tag for cleaning the main pipeline by workers starts at 250 rubles for each meter of pipe. I usually calculate the final amount based not only on the length of the sewer, but also on the complexity of the pollution/blockages.

A personal portable installation can be purchased for at least 125 thousand rubles (for example, made in the USA or the domestic Arzamas plant). A high-quality, complete hydrodynamic washing machine will cost about five hundred dollars (Kärcher or Rotenberg).

Hydrodynamic sewer flushing fully justifies the financial costs, as it long delays the need to replace sewer pipelines, extending their service life.

Structural elements

The most common, according to buyers, is considered to be hydrodynamic technology. It consists of the following key elements:

• drive (internal combustion engine or electric drive);
• containers for saving working fluid;
• pump;
• flexible hoses in metal corrugation for high pressure;
• drums for winding hoses during storage;
• a set of nozzles with holes;
• frames with wheels (for popular expensive models);
• devices for cleaning filters and nozzles.

The best manufacturers have launched the production of popular models equipped with a gun for washing sidewalks, facades and vehicles.

Types of nozzles

There are several types of nozzles installed on the working hose of a hydrodynamic apparatus:

Types of devices

The following types of equipment are used to remove blockages:

• hydrodynamic;
• gasoline;
• high pressure;
• manual;
• stationary;
• drum type.

Let's look at each option in more detail.

• The device may only be operated and maintained by a person with experience and relevant knowledge;
• if a popular model has an electric motor, then an electrical network is needed.

What types of hydrodynamic machines are there? They are divided into the following types:

How to choose the right model? Experts recommend paying attention to the following aspects:

1. Hose length. If the need arises, the hose can be purchased at any length and installed.
2. Type of drive. Can be internal combustion or electric. If electrical networks are installed and there are no power outages, then it is better to opt for electric models.
3. Nominal pressure. Selected depending on the thickness of the elements being cleaned. If the hydrodynamic impact is insufficient, then a positive result will not be achieved. The nominal pressure must match the flow. The drive and pump power can be reduced. For this purpose, the manufacturer provides special regulators in the unit.

The following types of nozzles are produced for hydrodynamic units:

• to remove fat;
• universal;

Methods for removing blockages

The reasons for the deterioration or cessation of sewerage may be different:

• due to oversight or careless operation, a large insoluble object that accidentally ends up there may get stuck in the pipe, or a blockage may form due to food waste or large debris thrown into the toilet;
• due to violation of installation technology - if the slope is not observed, a large number of turns of the pipeline or insufficient cross-section of pipes, wastewater moves through the sewer slowly, stagnation occurs, particles suspended in the water precipitate, garbage and sewage accumulate in network nodes;
• from prolonged use, the throughput of any pipeline gradually decreases, since wastewater contains fats, lime and other substances that build up on the internal walls.

If an obstruction in the sewer network is detected, they immediately begin cleaning it using one of the following methods:

• Hydromechanical - install a plunger on the drain hole and, pressing the handle, set air and wastewater in motion, pushing the blockage further along the pipeline. This old method helps with small blockages and when large objects get into the pipes, especially if the blockage is close to the drainage point. But a plunger will do nothing to help with growths on the walls.
• Chemical - factory-made or self-made compounds are poured or poured into the pipeline, corroding grease, rust and limescale. The chemicals can easily deal with small build-ups and small household waste, returning the lost capacity of the sewer system in a few hours. Personal hygiene items, large garbage and leftovers, perennial and already hardened growths on the insides of the sewer system may not be dissolved by chemical compounds.

Important! Chemical drain cleaning is recommended to be carried out regularly - once every one to two months, and not only in the event of an accident. Continuous preventative maintenance helps maintain pipeline functionality.

• Mechanical - use a plumbing cable, pulling it through the sewer hole manually or with a special machine. Using a cable with various attachments, you can push the plug or pull out a foreign object that has gotten there, and remove build-ups on the inner walls of the pipes.
• Hydrodynamic - they use a machine that has a flexible hose instead of a cable that supplies powerful jets of water to the problem section of the pipeline. Obstacles are destroyed under pressure and carried away by the flow further through the pipes.

Important! When hydrodynamically cleaning a sewage system, a large volume of contaminated water enters the collector. To prevent the collection well from overflowing, pump it out before starting work or during the cleaning process.

Pros and cons of using machines

It is worth noting that using sewer cleaning technology has many advantages. This list includes:

• ease of use;
• speed of problem resolution;
• accuracy;
• no mechanical damage;
• environmental safety of the method;
• the units can be operated at sub-zero temperatures;
• after completion of the work, the system functions “perfectly”;
• efficiency is achieved when working with products of any diameter and the presence of turns and bends.

There is only one drawback - the price. If you intend to use the equipment one-time, it is better to seek help from specialized organizations that provide this type of service.

Hydrotreating of internal and external sewerage systems, differences

Internal sewerage to pipes laid directly from the plumbing to the first compartment of the septic tank/sewage well. When cleaning these pipelines, not only water is used, but also reagent solutions for better removal of grease deposits, PAV.

Flushing internal sewerage with a hydrodynamic machine

External sewerage to pipes running from manholes to the central sewerage system. In this case, cleaning is carried out step by step. Pipe sections are washed under pressure, after which the waste liquid is pumped out with a pump. External sewerage is cleaned using one or even two machines (the first is for cleaning, the second is for pumping out wastewater and sediment). Typically, external sewer pipes have a large diameter and, accordingly, a significant amount of sediment.

Hydrodynamic sewer cleaning

Preventive actions

The risk of blockages can be reduced. To do this, it is enough to comply with the following requirements:

1. Do not throw foreign objects, both inorganic and organic, into the sewer. Plastic bags, personal care products, and construction debris can cause clogs.
2. If there are problems with the passage of liquid, it is worth checking special siphons to ensure their cleanliness. Accumulated debris should be removed and the interior should be thoroughly rinsed.
3. It is advisable to clean the system with chemical components once every three months. This could be vinegar, soda, or chemical solutions specially designed for this purpose. After using them, the pipes are thoroughly washed with hot water.
4. It is advisable to install metal or plastic gratings in the bowl. They will trap large particles and prevent them from penetrating into the system.

Instructions for using the equipment

To use the equipment correctly, the first thing you need to do before the procedure is to determine the nature of the blockage. This will help you select the required nozzle. After this, it should be installed on the hose and you can proceed directly to cleaning the pipes.

The hose should be inserted into the pipe to a depth of approximately 1 meter through a special hole or toilet. Next you need to turn on the water. The hose will move independently to the place of blockage under the pressure of water. The procedure must be carried out until the problem is resolved. After this, the hose and nozzle must be thoroughly rinsed with warm water.

Kinds

The following special devices are used to clean sewer pipes:

1. Electrical and mechanical machine;
2. Hydrodynamic;
3. Combined.

The hydrodynamic device is widely used by modern plumbers to clear pipelines from severe blockages. Most often these are pieces of trees, stones, fabric and other objects that interfere with the normal discharge of wastewater. In addition, the hydrodynamic machine frees the pipe walls from feces and small mineral deposits.

The mechanical and electric drain cleaning machine is quite easy to use. Most often it is used to insert a cable into the sewer pipe system to clean the pipeline. It is quite difficult to push the cord by hand to the point of blockage, while mechanically this task is greatly facilitated. Sometimes, to ensure a more reliable or deeper dive, craftsmen use pneumatic mechanisms or low-power electric motors.

Mechanical apparatus

A combined machine is a combination of the functionality of several described models (Speedrooter). Most often they are represented by a combination of the functions of hydrodynamic and mechanical options. Using this device, you can clean sewers both with high-pressure water pressure and by inserting a classic plumbing cord into the pipeline. Sometimes a similar petrol-mechanical machine is used.

Electric cleaner

It is impossible to make such a device with your own hands. The closest you can get to drain cleaning is using a water hose that delivers high-pressure liquid into the pipeline without using a special machine. If you urgently need pipe cleaning, equipment rental is available in all cities.

Types of attachments for hydrodynamic machines

Hydrodynamic cleaning attachments

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