In some cases, the occurrence of suchproblems like wastewater removal from the facility. Most often this arises because of the problems made at the design stage of the sewage system. In such cases, quite often resort to this method of solving the problem, as the installation of the well-damper.
The main purpose of this deviceis that it must exercise constant control over the speed of movement of the flow of fluid flowing inside the pipeline. If we talk about the overall design of this device, the well-damper is a kind of control or regulation unit, without which it is almost impossible to influence the operating parameters of the line.
The most relevant this deviceIt is considered in the event that it is necessary to deal with the self-flowing storm sewer. Most often, in such systems, the liquid travels fairly long distances, being redirected from the object to the nearest reservoir or gutter. In such networks, a well-damper is an indispensable and necessary thing, since it can be used to adjust the flow rate at a selected site. Thus, it is possible to change the pressure acting on the walls of the pipeline.
No wonder it says that everything ingenious is simple. The principle of the well-damper is quite simple, but at the same time very effective and in some cases is an essential element.
Initially, the liquid does not immediately enter the pipessewage, and into the tank where the accumulation of matter takes place. After the tank is filled, the pumps that transfer the liquid to the drains and from there to the sewage system start up. If we talk about the device of ordinary domestic sewage, the capacity means a sump. If we talk about sewage of an autonomous type, then a well of a drainage type is used as a reservoir.
Well-damper head installed inautonomous sewage, will filter the resulting fluid, and then redirect it to the ground so that it is absorbed. The only thing to add is a tie-in to this tank of all local pipelines. However, this is only relevant if there is a central main water flow in the village or village.
Установка колодца-гасителя для канализации will be most appropriate in the place where there is the greatest intensity of the flowing fluid flow. Such a place is most often a segment located between the location of the pumping equipment of the station and the place of tie-in into the system. It is worth noting that the installation of this equipment is most often accompanied by the installation of an additional manhole. This set of devices will do an excellent job with the task of quenching the excessive value of fluid pressure on this section of the path.
Как уже стало понятно, колодец-гаситель напора for sewage, it is “engaged” in changing the intensity of the flow of fluid flowing through pipes. That is, to quench the flow, it is necessary to change its intensity, but it is important to note here that this does not help in all cases.
In some situations it may happen thattoo much pressure drop will be noticeable. In such places most often observed such a defect, as a slight flooding of the system. During the construction of a sewage system for any object, special attention should be paid to such an issue as the analysis of changes in the flow rate of liquid through the pipeline. To do this, use hydraulic formulations and meanings.
For typical dummy wells with these valuesThe following parameters appear: water properties, viscosity both dynamic and kinematic, pipeline length, as well as pipe diameter at certain parts of the system. In addition, you need to take into account such factors as consumption, turning radius. This is very important, since these indicators will have a significant impact on the speed of movement of the fluid when it is pumped.
Типовой проект колодца-гасителя - это план, по which is the installation of this device. This document may be changed in the course of the work due to the fact that calculations will be made of this structure for a particular object or specific landscape conditions. Engineers must make a hydraulic calculation in which it is necessary to take into account such characteristics as the landscape slope, pipe length, viscosity and fluid flow parameters. This must be done in order to properly select the diameter of the well, as well as the pipes, correctly determine the radii of the turning parts and so on. Documents on typical wells-dampers should include in their composition and such papers as the layout of the pipeline on the ground.
The design of this device is a tank.cylindrical type with a bottom to which several pipes are attached at different heights. Waste water enters the tank through the upper section of pipes, and is discharged through the lower section. Thanks to this method of water withdrawal, the head is quenched by approximately 17-20%.
Drawings of the well-damper head should be made with notes, explanations, have the specification of materials, as well as products with a full calculation of the required quantity.
What are the reasons why there is too much pressure in the pipes? There are two reasons for this.
The first and main reason for this phenomenonis that the entire system was originally planned incorrectly. It may happen that the pipes were chosen of small diameter, and the pump is of sufficiently large capacity. These factors are quite enough to create excess pressure. Although this property is the opposite, and increased pressure may occur due to lack of fluid in the system. There are other reasons for this increase, for example, too much slope of sewer pipes.
Sewage well-absorbers most oftenmounted on the section between the pump and the sewage treatment plant. It is important to note here that this device, besides its main function, can play the role of a transfer or a rotary well.
The first device will be used in orderto combine a variety of communication, located at different levels. Or, this unit can be used to circumvent various obstacles, due to which the laying of the pipeline in this area becomes impossible. This could be, for example, the foundation of a building, other communications, etc.
Rotary same type of well, as follows from itsname is needed in order to rotate the pipeline system. It is important to note that such places most often become places of impulse. Because of this drawback, experts recommend making a mine, which will allow to monitor the condition of the pipe.
In order to carry out the installation of the usualwell-damper, often used concrete rings. In addition to these materials, it is also necessary to have a concrete base and cover. It also happens that the time of installation of the absorber falls on the time when the sewer communication of the object is laid.
To begin work it is necessary to prepare the mine.The depth of this section will directly depend on the depth at which the sewer pipes are located. At the bottom of the mine is placed a concrete base, and then begin mounting rings. The pipe is inserted into the well through a pre-prepared opening in the tank. In advance, it is necessary to make another hole to which the pipe will be connected, which serves to drain the liquid. Elements such as water hammer dampers will ensure a smoother movement of water into the treatment plant. Thanks to this function, it will be possible to greatly increase the service life of not only the pipeline, but also the cleaning tank itself.
