Sewerage has an unpleasant feature - from time to time it gets clogged and needs to be cleaned. Since this is dirty and unpleasant work, human power is not used to carry it out. Instead, they use a special sewer cleaning machine.
Hydrodynamic unit
The working tool of this type of mechanisms for cleaning sewer pipes is a hose through which water is supplied under pressure. A cone-shaped steel tip is fixed at the end of the hose, which has openings over the entire surface. A large pressure of water in combination with narrow slots create a high pressure of thin streams of water falling on the entire inner surface of the sewer pipes.
The average pressure that hydrodynamic cleaning exerts on a dirty surface is 300 kg / sq. see. The advantage of this type of sewage treatment machine is that it does not damage sewer communications. Also a plus system in its mobility. A flexible narrow hose can take any shape, and this allows you to work in pipes of the most complex configuration.
The working mechanism consists of a high power water pump that feeds liquid into a fixed hose. The pump is driven by an engine. He works on an electric drive. The distance at which water can be supplied under effective pressure is approximately 100-150 meters.
The nozzle can be divided into front and rear parts. In front, as a rule, there is one hole directed directly in the direction of movement of the hose. It is designed to eliminate blockages that impede the progress of the hydrodynamic treatment device.
In the rear part along the perimeter there are several smaller holes that supply water to the walls and wash away dirt, grease and even the sprouted root system of trees. The rear holes are not directed directly to the walls, but at an angle of 15 to 45 degrees. This design ensures the movement of the nozzle with a hose due to the buoyancy force of water. Hydrodynamic machines Poseidon is one of the most popular brands of treatment systems in Russia.
Sewer gasoline cleaning machine
A gasoline sewer cleaning machine is also called a waterjet apparatus. The main advantage is that it has high power and increased productivity. Such a unit is powered by a gasoline engine, so it can be used autonomously, without being tied to a wall outlet or other stationary power source. This allows you to work in the most remote places from the power supply.
The advantage of gasoline cars is that they can perform certain functions automatically. For example, to regulate the pressure with which water is supplied to the hose, depending on the degree of contamination of the sewage system and the complexity of passage through it.
On the case, inside which the motor is installed, there is a manometer, a safety valve and an ignition switch, which starts the unit. On the side or under the bottom is a filter system. There is another distinguishing feature - the presence of an outlet.
Electric drum cleaning machine
The drum pipe cleaning machine consists of a spiral hose, an electric motor and a drum. The engine drives a drum that quickly scrolls the hose around its axis. At the end of the hose there is a point with which dirt is cleaned from the sewer pipe. Due to the rapid rotation, the spiral with the tip, like a drill, bites into the blockage and clears it.
There are cleaning machines, the drum of which is not driven by the engine, but by manual scrolling. Such devices are favorably characterized by low weight and size, which allows you to quickly carry it in your hands. The disadvantages of drum cleaning machines include the length of the spiral hose. It ranges from 4-10 m. This means that such a device is not suitable for deep blockages.
High pressure machine
The high-pressure sewer cleaning machine is used in areas with particularly severe blockages that other devices cannot cope with, or for quick cleaning of a large area. The water pressure provided by such a cleaning machine can reach 180 atm. However, the minus is that the device gives such high productivity at a distance of no more than 40-50 m.
A high-pressure machine is considered more wear-resistant than analogues of other types. This is ensured by smooth pressure control and a pump with three plungers moving in an oil bath. The latter circumstance protects parts from excessive friction, since they do not work dry.
Criterias of choice
The secret to effective wastewater treatment is to use a machine of the type that is better than others in specific conditions. It is desirable to choose, evaluating such criteria:
- application area;
- price;
- the size;
- motor power;
- effective range;
- pressure under which water is supplied;
- presence / absence of wheels for transportation;
- availability of additional functions;
- variety of nozzles, hoses and cables.
Most often, people have to clean the sewage system in a domestic environment. For work in home sewers, a hydrodynamic machine is better. It is the most compact in size, does not take up much space. The hose of the hydrodynamic machine is thin, rarely exceeding 30 mm in diameter, so it is ideal for thin sewer pipes in a residential building. Cleaning household waste, such as fats and food waste, does not require high power.
To clean pipes from plastic, steel or asbestos cement, it is most advisable to use a drum electromechanical cleaning machine. There are also sectional cleaning machines that allow the use of equipment and parts with a wide variety of cable lengths, diameter of hoses and pipes, as well as types of cleaning. They relate to professional equipment used by utilities and management companies, thanks to a wide range of applications. Such a cleaning installation is perfect for large areas where sewer canals of various types and sizes are located.
How much is the equipment
Prices for electromechanical devices for cleaning sewer pipes depend on the power and type of device. The most expensive cleaning machines are sectional. Their high cost is due to the possibility of use in various situations, since they are equipped with a large set of hoses, cables and nozzles. A typical specimen is Krot-88. Prices for such devices reach 250 thousand rubles.
Drum, gasoline and hydrodynamic types of medium-sized devices that are equipped with wheels for movement will cost 25–75 thousand rubles. Their price is several times lower because such types of treatment machines are intended for wide use, and sectional ones are positioned as specialized equipment.
The cheapest are manual, small-sized cleaning machines. Prices for devices manufactured by Rotenberger, which can be kept even in an apartment, start at 10 thousand rubles.
