Drain pump for the well, features a selection , installation , cleaning of wells
Drain pump for the well is used for pumping water. Typically, this equipment is used if the degree of pollution of water is not large . The purpose of this unit , types of pumps , advantages and disadvantages of each, especially start-up – all this will be discussed in this article. In addition, we have led the technology yet another application of drainage pumps – the cleanup well.
Scope of the drainage pumps
Such equipment is extremely important in the following cases:
for pumping water in the aftermath of accidents;
When a cluster of flood water in the basement and ground-floor rooms;
with excessive lifting of the water table ;
during the cleaning of artificial water bodies , such as drainage pump for the pool will ensure compliance with the relevant hygiene requirements ;
for heavy prolonged rainfall ;
for the organization of the water supply for the operation of ornamental fountains ;
drain pump is used for irrigation in the organization of drip irrigation for large areas of greenery .
Types of drainage pumps
There are two types of drainage pumps:
Submersible pumps – before turning their way to the bottom of the object that is cleaned ( distinguish vibration submersible pumps and centrifugal submersible pumps) – this equipment is very popular with owners of country houses and suburban areas due to the ease of use, low price and the possibility of installation and replacement on its own;
Surface pumps – the water when the unit is lowered only hose.
Features of submersible pumps
Like all equipment submersible pumps have their own characteristics . The most important are listed below.
have small dimensions ,
relatively light ,
designed for continuous operation without any special maintenance ,
are versatile as they can be used for pumping and clean, and highly contaminated water
characterized by high productivity (up to several tens of cubic meters. meters per hour)
equipped with a float protected from drying ,
can be used in automatic mode in sewage and drainage systems.
submersible drainage pumps for wells can not provide strong water pressure – the maximum water can be raised to the level of 20 m ( average rise of water is about 10 m),
when such equipment is not cleaned water is pumped – pollution contained in it, can cause clogging of the different systems where the water supply is therefore not recommended to use this type of equipment in water systems .
Features of surface pumps
The surface-type pumps also have their ” pros ” and ” cons .” The advantages of surface pumps:
power of water pressure , which allows transfer fluid to tens of meters ;
increased reliability of the lack of diving pump into the liquid medium ;
the ability to install the equipment in the house and , as a consequence , no need to take stock supply to the well ;
availability of the pump in continuous mode ;
acceptable price .
Consider also their drawbacks:
inability to use in deep wells (deeper than 9.7 meters) due to the low suction head ;
high noise level during operation, causing, in some cases, the need for a separate technical areas ;
the need for skills in the correct use of the suction line .
Installing the drain pump for well
Pump well as quite simple to install and to operate. However, the equipment is working properly and for a long time , the installation must be carried out by following certain rules.
So, the installation instructions :
Pressure line ( pipe or hose ) is connected to the discharge connection , securing the necessary fittings.
If the pump is equipped with a float switch and will be used for stationary applications , you must install the pressure line check valve .
The unit with the three-phase motor must be checked for correct rotation . The pump is mounted on a flat surface , include, and then immediately turn off . At that point , in which direction the pump shaft turns :
if clockwise – the device is connected correctly ;
if counter-clockwise – you need to change two phases .
When the unit is connected to the pipeline , so check the correctness of the rotation :
connect the power supply and measure the flow ;
turn off the power supply, phase change places and repeat the first point ;
comparing the power supply and determine which one is the correct way to connect phases .
The pump is mounted in a vertical position with the discharge nozzle should be facing up.
Dip the pump at the bottom of the well.
Cleaning the well with drain pump
When choosing a suitable model to study the instructions carefully , since some types of sump pumps are designed for pumping clean water. At the same time there are models that do an excellent job with the water containing various impurities , including fibers and small inclusions .
Cleaning the well drain pump will be easier if use equipment having a float which is a special switch, floating on the water and the stopping of the pump in the case if it reaches the bottom. When the pump is used without the need to float the work equipment constantly monitored to prevent overheating of the pump motor has appeared on the surface ( the water in which the pump is immersed , the function of the cooling liquid).
In organizing the cleaning work well with drain pump man no need for a dive – the pump does all the work automatically. However, it is important to set it up :
first pump is immersed in the depth not reaching the bottom of 0.5-1 m
Pump included – the pumped water is cleaned of contaminants
the next step clean water under pressure enters into the well, which occurs during the degradation sludge at the bottom thereof ,
pump periodically raised and filter to clean it , as long as it does not appear muddy sediments .
Sometimes after a major cleaning pit sump pump is left on the bottom to keep clean . It is recommended once every six months or a year , depending on the composition of the soil to carry out cleansing of pump filters .
Well proven practice cleaning wells, in which , using a powerful drain pump clean water well once in 1-2 years. The cleaning process is typically one week, and then the pump is stored in a clean, dry environment.
