The sewage system has an unpleasant feature - from time to time it clogs up and needs to be cleaned. Since it is a dirty and unpleasant job, no human power is used to do it. Instead, a special sewer cleaning machine is used.
Hydrodynamic unit
The working tool of this type of mechanisms for cleaning sewer pipes is a hose through which water is supplied under pressure. At the end of the hose, there is a tapered steel tip that has holes along its entire surface. The high pressure of water in combination with narrow slots creates a high pressure of thin jets 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 cleaning machine is that it does not damage sewer lines. Also a plus of the system is its mobility. Flexible narrow hose is able to take any shape, and this allows work in pipes of the most complex configuration.
The working mechanism consists of a high power water pump that delivers fluid to a fixed hose. The pump is driven by the engine. It is electrically driven. The distance to which water can be supplied under effective pressure is approximately 100 - 150 meters.
The attachment can be conditionally divided into front and back 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 interfere with the advancement of the hydrodynamic cleaning device.
In the rear, there are several smaller perimeter holes that supply water to the walls and wash away dirt, grease and even sprouted tree roots. The rear holes are not directed to the walls directly, but at an angle of 15 to 45 degrees. This design provides the movement of the nozzle with the hose due to the buoyancy of the water. Poseidon hydrodynamic machines are one of the most popular brands of treatment systems in Russia.
Gasoline Sewer Cleaning Machine
A gasoline sewer cleaning machine is also called a water jet. The main advantage is that it has high power and increased productivity. Such a unit is powered by a gasoline engine, therefore it can be used autonomously, without being tied to an 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 some functions automatically. For example, to regulate the pressure with which the water is supplied to the hose, depending on the degree of contamination of the sewer and the complexity of the passage through it.
On the body, inside which the motor is installed, there is a pressure gauge, a safety valve and an ignition switch, which starts the unit. A filtration system is located on the side or under the bottom. There is one more distinctive 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 the drum, which quickly turns the hose around its axis. There is a tip at the end of the hose, with the help of which the dirt is cleared out of the sewer pipe.Thanks to its fast rotation, the spiral with the tip, like a drill, digs into the blockage and clears it out.
There are cleaning machines, the drum of which is not driven by a motor, but by hand rotation. Such devices are favorably distinguished by their 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 fluctuates within 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 heavy blockages that other devices cannot cope with, or for quickly cleaning a large area. The water pressure provided by such a cleaning machine can reach 180 bar. However, the disadvantage is that the device produces such a 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 achieved by modulating pressure control and a pump with three plungers moving in an oil bath. The latter circumstance protects the parts from excessive friction, since they do not run dry.
Criterias of choice
The secret to effective cleaning work is to use the type of machine that is best suited to the specific conditions. It is advisable to choose by evaluating the following criteria:
- application area;
- price;
- the size;
- motor power;
- effective range;
- the pressure under which the water is supplied;
- presence / absence of wheels for transportation;
- availability of additional functions;
- variety of attachments, hoses and cables.
Most often, people have to clean the sewer in a domestic environment. A hydrodynamic machine is better suited for work in a domestic sewage system. It is the most compact in size and does not take up much space. The hose of the jetter 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 grease and food waste does not require high power.
To clean pipes made of plastic, steel or asbestos cement, it is most advisable to use a drum electromechanical cleaning device. There are also sectional cleaning machines that allow you to use equipment and parts with a wide variety of cable lengths, hose and pipe diameters, and cleaning types. They are among the professional equipment used by utilities and management companies due to their wide range of applications. This cleaning unit is perfect for large areas with different types and sizes of sewer channels.
How much does the technique cost
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 using them in various situations, since they are equipped with a large set of hoses, cables and nozzles. A typical specimen is Mole-88. Prices for such devices reach 250 thousand rubles.
Drum, gasoline and hydrodynamic types of devices of medium size, which are equipped with wheels for movement, will cost 25-75 thousand rubles. Their price is several times lower because these types of cleaning machines are intended for widespread use, and sectional machines are positioned as specialized equipment.
The cheapest are small hand-operated cleaning machines. Prices for devices manufactured by Rotenberger, which can be kept even in an apartment, start at 10 thousand rubles.
