before pumping clean water from the well of possible surface contamination (twigs, sticks, leaves).To do this, it's best to use a ladder of appropriate sizes, as well as help mate.
lower the ladder into the mine pit and securely set on the ground.Lifting of objects on a surface can be achieved through manhole gates and with a cable attached to the lower end of its capacity.As a container, use a bucket, pot or basket.Raising the load on the ground surface, use caution.
If the bottom of the pit is covered with a substantial layer of silt, use for its specialized pumping Cesspool emptying trucks.Order can be in
an organization engaged in sewage and drainage works.One such machine is enough to deflate at a time from the well up to 10 m3 of silt and other contaminants.
After the liberation of dirt inside of the well set it pump.For wells with a water level of more than 1 m, use a submersible pump, at a lower level would be suitable and the surface.
While installing pumps in the mine, be sure to secure his safety rope, a supportive pump.The cable may be made of nylon or stainless steel with a thickness of 3 mm.The lower part of the pump at its operation should not touch the bottom.
Turn on the pump and make pumping water from the well.Time of complete liberation of the well is determined by the hydraulic characteristics of the intake (the size of the well, the speed of water flow, and so on), as well as the capacity of the pump used.
After pumping water out additional cleaning of the bottom and walls of the well.If necessary, renew the "cushion" of river pebbles or gravel.In order to treat the walls of disinfection with chlorine solution using a large brush or spray.Such prophylaxis is recommended at least once a year.
Tip 2: How to pump water
deflate water from the swimming pool or the well - no laughing matter.Here, a pair of buckets can not do.For pumping large volumes of water, there are special pumps, separate models that are easy to use, compact and reliable.
order to siphon clean or slightly contaminated water , you will need to drain the submersible pump.This pump is equipped with a float switch type that is able to automatically disconnect the device when the water level drops below the allowable.And when it reaches a predetermined level automation itself includes a pump.
submersible pump is very suitable for the pumping of water from the swimming facilities, clean water wells, cellars, with intake of artificial reservoirs or rivers.It is compact and easy to maintain.
Such a pump may be used in irrigation systems, as well as to lower the groundwater level.Permissible content of mechanical impurities in the pumped water, sometimes up to 5% of the volume of water.Typically, there are limitations to the linear dimensions of foreign particles - not more than 5 mm.Consider only that small stones and metal objects the pump is too tough.
Of course, such a pump has a well-defined scope of application and can not be used in the production of construction works, as well as in pumping sewage.One of the advantages of the drainage submersible pump - protection against dry running, which helps to prevent it from incorrect handling and failure.
most of the pump housing is made of plastic or stainless steel.There are models made of cast iron.This design allows for submersible pump high reliability and durability even under difficult conditions.
Choosing to fit your needs specific model pump for pumping water, pay attention to the lettering.If the letters are missing, the unit is made of plastic and is designed for pumping clean or slightly contaminated water.The letter "H" stands for the pump of the "Stainless Steel", "F" - pump for pumping dirty water.
