Basic information about the
The stations have the main function of pumping out liquids:
- natural water drains,
- technical water,
- waste water discharge,
- il.
The CNS mechanism depends on their purpose. For example, household pumping stations have completely different properties from technical stations. CNS can be of different shapes in the vertical and horizontal. Its upper part necessarily represents a throat equipped with a polymer or stainless lid. Sewer station of the household sample is equipped with a trellised hatch, serving as a kind of protective layer against foreign contamination.
The internal volume of the cnc is a pipe that passes water. Powerful fluid flows that pass through the pipes are eliminated by the water wall of the reservoir.
Danger of contamination when pumping out water falls specifically to the recycle bin.
In the event of a breakdown of the sewerage pumping stations, sewage pumping stations are equipped with special platforms and ladders, allowing specialists to inspect the parts and without any unnecessary inconvenience to repair them.
The device itself pumped water through the side openings of pumping stations. Avoid a strong flow of water when pumping out the drains helps the bump, it provides a uniform flow of liquids.
Operating modes of
- stations Manual.
Its purpose is to use it under repair conditions, full pumping out of sewage channels, launching a new cnc. - Automatic.
Its purpose is in daily routine mode.
Modular Sewage Pump Station Operation Mechanism
Solid particles in the drain, complex pumping, are realized on the surface thanks to the modular pumping stations, which are:
- form: cylinder,
- diameter: 80-300 cm,
- height: approximately 12 meters,
- construction material: reinforced fiberglass.
Functions - due to the massive nature it can withstand the pressure of soil, sewage and groundwater, additional repair or process equipment.
CNS sewage pumping stations consist of parts:
- pumps operating with deep water,
- internal plumbing,
- additional fittings,
- connecting lines( sockets),
- devices responsible for automatic operation,
- control panel.
The design of sewage pumping stations involves the use of the following components for their design:
- stainless steel,
- reinforced fiberglass,
- PVC.
The choice of these materials is due to their resistance to corrosion, durability, long operation and low cost.
Calculation procedure and design of CNS
Calculation of the pumping system consists of:
- selection of pumps,
- calculation of their capacity.
Incompetent person in accurate calculations it is better to seek professional help. An error made during the calculations may adversely affect the quality of the pumping structure.
A typical design of sewerage pumping systems consists of rigorous calculations in a specific order:
- Calculation of the use of the amount of water
- Drawing a graphic image of the inflow of waste water at different times of the day
- Based on the second point, the flow rate is calculated
- Calculation of the minimum and average water flow
- Calculation of power( head) of the pumping station by the formula:
H = HГ + hп.в + hp.n.
Explanations:- HH -height of wastewater lifting( m),
- hp.в - hydraulic losses of suction line pressure( m),
- hp.n - water leakage in the pipeline,( m).
- Comparison of calculation results for a specialized catalog of pumping stations
- Drawing up graphical schemes "Maximum head - flow rate of liquids".
- Accounting for work risks for the system "CNS sewage pumping stations in extreme circumstances"
- Interactive calculation of receiving capacity.
Installation of the CNS involves a certain preparation of the installation site. Specialists recommend concreting the place of immersion of the pumping station from the flow of groundwater and excess moisture.
