New SPS sewage pumping stations : approaches, methods , characteristics

Summary of CND

stations have the main function of pumping liquids:

• natural water flows,
• technical water,
• drain waste,
• silt.

SPS mechanism depends on their destination.For example, household pumping stations have quite different from the technical characteristics of stations.SOS may be of different shape both vertically and horizontally.Its upper part is definitely a mouth equipped with plastic or stainless lid.The sewage plant is equipped with household sample trellis hatch serving kind of protection from extraneous contamination layer.

internal volume of the KNU is the pipe, permeable water flows.Powerful fluid streams flowing through the tubes eliminates stilling wall of the collector.

adjudged contamination when pumping water fall a specially designated cart.

When damage SPS sewage pumping stations equipped with special platforms and stairs, which allow experts to examine details and no extra inconvenience to deal with their repairs.

The device produces pumping water through the side holes of pumping stations.Avoid strong stream of water at a sewage pumping helps bump, it provides a uniform flow of liquid.

Modes

1. Manual station.
   
   His mission - to be used when repairing the circumstances, complete sewage pumping channels, launch of a new SPS.
2. Automatic.
   
   His mission - in daily normal mode.

mechanism of the modular sewage pumping station

Particulates in the gutter, complex pumping, realized on the surface thanks to the modular pumping stations, which are:

• form: cylinder,
• Diameter:80-300 cm,
• height: about 12 meters,
• construction material: reinforced fiberglass.

functions - thanks to massive soil can withstand the pressure, waste and ground water, additional repair or production equipment.

SPS sewage pumping stations consist of parts:

• pumps, working with deep waters,
• indoor plumbing,
• additional reinforcement,
• connecting lines (pipes),
• unit responsible for the automatic operation,
• switchboard.

project pumping stations intends to use in their construction of the following components of materials:

• steel, stainless steel,
• reinforced fiberglass,
• PVC.

choice of these materials is due to their corrosion resistance, durability, long life and low cost.

procedure for calculation and design of the CND

Calculation of the pumping system is:

• range of pumps,
• calculation of their volume capacity.

incompetent person in the exact calculation is best to seek professional help.The mistake made in the calculation, may adversely affect the quality of the pump design.

Model project of sewage pumping systems consists of rigorous calculations in a certain order:

1. Calculation on water quantity
2. Building a graphic on the inflow of wastewater at different times of the day
3. Focusing on the second point, held effluent flow calculation
4. Calculationminimum and average water flow
5. power Calculation (pressure) pump station according to the formula:
   
   H = collar nut + + hp.v hp.n.
   
   Explanation:
   • collar nut-height lift waste liquid (m),
   • hp.v - hydraulic head loss of suction piping (m),
   • hp.n - water leak in the pipeline (m).
6. comparing the results of calculations by specialized directory
7. pumping stations Drawing graphic schemes "Maximum pressure - fluid flow."
8. Accounting risks of work on the system "SPS sewage pumping stations in extreme circumstances»
9. Interactive calculation receptacle.

Installation ANC suggests some training place of its installation.Experts recommend concreted dive site of the pumping station on the flow of groundwater runoff and excess moisture.
