The installation of vacuum water use UVV -SZA -6 km is designed for a construction of soils with a filtering coefficient of 0.1–2.0 m/day (fine -grained, dusty and dust clay sands, sandy loams, silts, forests) and in some cases with a filtration coefficient of 2.0-15.0 m/day (fine -grained, sometimes medium -grained sands).
The installation of UVV -SZA -6 km consists of a suction system and a pump unit.
The absorption system includes a suction collector, needleofilters, connecting sleeves, a receiving and transitional sleeve for water and air.
The pump unit is a single block mounted on the frame and including a centrifugal pump, an ejector cassette and a circulation tank, stabilizer of the flow, control valve and mud-ejector Gryazeva. P>
The determining feature of the installation is its ability to pump out from the suction collector and needleofilters , which gets there in case of a significant decrease in groundwater level.
Characteristic a feature of installing a vacuum type of UVV is its ability to pump out a water mixture with a large content of air that gets there in case of a significant decrease in the level of ground water. This factor often becomes decisive when choosing the required equipment for draining construction sites after the necessary hydrological surveys and design work in such cases.
Installation of UVV consists of a pump unit and absorption system.
The absorption system includes:
- Having absorbed;
- connecting sleeves;
- Reception block;
- transition sleeve for water and air.
- centrifugal pump;
- ejector cassette;
- circulation tank;
- Stabilizer of the flow;
- control valve;
- Gryazeva ejector.
The pump unit is presented in the form of a single block mounted on the support frame.
it includes:
A distinctive feature of the installation of WHI Water use is its the ability to suck from needleofillers and absorbing collector , which gets there when a significant reduction in the level of groundwater occurs.
