The principle of operation of machines for cleaning sewer pipes

Nobody remembers the sewer system until it goes down for various reasons. Depending on the type of blockage, an appropriate tool is used to clean the sewer pipes.

Types of sewage cleaning equipment

If clogging occurs due to a violation of the technologies for laying sewer pipes: non-compliance with the inclination angle according to SNiP, cornering at 90 degrees in the horizontal plane, insufficient pipe passage or wear of the system, the measures taken will be temporary. The only way out is to remodel the sewage system, since the equipment for cleaning the sewage system with technological blockages will not help.

Mechanical blockage occurs when rags, diapers, cell phones and other foreign objects get into the pipes. In this case, the removal of a foreign element is required.

Another type of blockage - operational - occurs due to deposits on the inner surface of the pipe system, as a result of which the passage opening narrows, the flow of contaminated water becomes difficult. Particles of fat become the cause of the resulting deposits, which freezes in the cooled effluents and settles on the surface of the pipes, taking other impurities with it.

As improvised means to eliminate blockages, several methods are used:

• mechanical - with the help of a plumbing cable or plunger;
• chemical - using home remedies, soda and vinegar, or special compounds, for example, Mole;
• thermal - supplying water of high temperature, while adding salt or soda;
• hydrodynamic - using professional cleaning machines that supply a stream of water under pressure.

In order to prevent operational clogging, periodic cleaning with chemical agents should be carried out without waiting for a sewer collapse.

Mechanized cleaning

In the event of blockages in hard-to-reach places, complete blockage during siltation of the pipe system, or at a sufficient distance from the house, a sewer cleaning machine is used. It works on the principle of a plumbing cable. The design consists of a flexible cable with a spiral section wound on a drum and has a tip. The engine feeds the cable into the sewer pipe. With the help of such a device, blockages in areas up to 150 m long are eliminated.

Simple technology allows you to deal with blockage alone. For work, special gloves with metal pads are required. Action algorithm:

1. Locate the blockage and find a nearby manhole.
2. To eliminate the proposed item, select the appropriate tip.
3. Manually insert the cable into the pipe at arm's length.
4. Fix the location of the machine.
5. Press the start button, turning on the feed and rotation of the cable.
6. Try to push an object into the pipeline to another inspection well.

Tips made in the form of a conical spring or collet gripper are used for narrowing and bending of sewer paths, hydraulic locks and check valves encountered. Using these tips, you can grab and pull out a stuck item. If the blockage is formed from sand, silt or fat, take the tip in the form of a spiral cutter with serrated notches. The cutter cross section is selected with a slightly smaller size than the diameter of the sewer pipe.

When the cable moves, it is necessary to constantly add hot water; soapy or slightly alkaline solution can be added to it in order to soften the fat.

To clean the internal sewerage system, drum machines are used, in which the cable is put into the drum after work. One of such devices K-45 has a drive from a drill and allows you to clean pipes in the diameter of 20-75 mm to 15 m. The cost of the product is 32543 rubles.

For cleaning external networks used (RD-E). In the rod version, the diameter of the pipes being cleaned is 75-600 mm for a maximum length of 150 m. Spirals 32 mm thick. The device has more than 30 nozzles. Indispensable in the winter, when the use of washing machines is difficult. May remove roots and foreign objects. Advantages in simple and convenient operation, compact size and high power. The cost of 330,000 rubles.

Hydrodynamic cleaning

Professional plumbers use high-tech equipment to remove blockages with cleaning using a powerful jet of water. The advantage is the safety of devices and their effectiveness.

In the plumbing market, the manufacturer Karcher offers two lines of devices for cleaning sewer pipes: for the home foreman and for professionals. Their advantages are compactness, efficient operation without damaging the sewer joints. Allows you to flush complex wiring of the drainage system. Hydraulic mini-washer is designed for car owners, but has been successfully used to flush sewer pipes in an apartment and in a country house. Cars operate without the use of special chemical solutions, eliminate ice plugs.

When the device is operating, a jet of water under controlled pressure is fed into the sewer. All elements of the blockage are discharged into the sewage pit. Different types of nozzles are used, since the reasons for stopping the sewer flow can be different.

Alternatives

So that the company does not spend money on the purchase of expensive equipment for cleaning the sewer, you can rent it. In this case, the purchase will not stand idle, and the sewage will be cleaned professionally. The cleaning device is based on KAMAZ. Benefits:

• quickly leaves for the place of blockage;
• large tank.

A powerful installation solves serious problems and works where a plumber does not cope. It is used for industrial sewage and private utilities.

Using a Typhoon pneumatic gun, heating systems and sewer pipes up to 150 mm in diameter are cleaned. The piston builds up pressure in the cylinder, which is connected through a rubber nozzle to the socket of the sewer system. The trigger allows you to direct a powerful stream of air into the pipes and push the blockage. Cleaning length up to 50 m.

Recommendations for choosing equipment

The price of the Karcher device in a professional version, despite the excellent characteristics of the equipment and the quality of cleaning, which lasts for several years of operation, is quite high - about $ 500, which reduces the use of the machine for domestic purposes. The warranty for household appliances is 1 year.

Russian manufacturers offer several options for hydrodynamic machines.

For each model, prices are indicated taking into account the increase in the functionality of the devices: the use of longer hoses, a cleaning and punch nozzle, and a passage on the drum. The last representative is shown to compare devices when used in the home and as a professional technique. Hose length up to 90 m, 12 mm passage on the drum, equipped with 2 nozzles.

Devices with an electric wire require an electric network, so it is more convenient to use a gasoline engine in the country house and in the garage.

The cost of pipe cleaning devices

Prices vary depending on destination, design, materials and capacity:

• household devices from 10.5 to 87 thousand rubles;
• professional mechanical machines for cleaning up to 330 thousand rubles;
• with hydrodynamic cleaning up to 195 thousand rubles. for the brand Poseidon.

A wide range of products will help determine the choice of even an inexperienced novice plumber. Clean sewer improves living conditions in an apartment and a private house.
