Sewage pump house


Command-control equipment pumps
Suction or discharge pumps can be removed from state functioanare or automatically or manually.
Automatic operation is preferred because only in this way to avoid involvement of large numbers of people to regulate the operation of pumps in relation to flow variations.
But it is imperative that the version with automatic control and the ability to have manual override in case of failure on the automatic version.
If pumping station serving a total of more than 5000 inhabitants will be equipped with automatic control accompanied by manual control.
Automation is imposed depending on water level variations in the water catchment area.
Water level changes are a result of variation in the flow of wastewater come from households receiving basin residents through a pipe underground collectors ..
Collector basin level changes are transmitted to a device that can vary from station pumped flows.
Transmission level variations is made by a pneumatic floating.
The pneumatic transmission to eliminate the difficulties of operating the float drives.
To prevent clogging of the tube end of the underwater cable that is transmitting device orders to be placed on top of a steady stream of air tube that removes coarse suspension square tube.
Pressure in the tube depends on the water in the basin, the command switch and it’s going to turn the pump.
Pressure variations are transmitted to a control panel, located in the pump station to share a place away 0.00.
Exploitation pumping stations consist mainly of monitoring pumping aggregates, power pumps, lubrication and cleaning them.
Switchgear and automation and in particular should be cleaned plutitorii sensors and permanent to ensure the necessary flow pumping.

Ventilation plant
Mechanical ventilation plant will be and is necessary for a safe dispersal of any kind, and to maintain the interior temperature of a summer at 10 ° C above outside air temperature.
The ventilation will be composed of :                                                                                               
- A network of channels fresh air discharge station. By means of a centrifugal fan.
Fresh breath of air intakes will be fitted with front facade which is opposite to the receiving basin.
Mouth will be equipped with blind frame and wire mesh.
- Exhaust gas from fermentation and infiltrates the station will be through a axial fan mounted in a vertical channel whose outlet is mounted in the pump house floor
He channel will be mounted at least 2 m above the house and the outlet end piece will have to counter the wind, rain or snow for protection.
There is the version that the mouth pipe axial exhaust fan is provided to a front mount as high as possible. Fan motors will be mandatory type of explosion due to gas station pumps.

Light and power installations
The electric power supply is a high voltage connection connected to a station near the voltage transformer station at the required.
Light and power plants include protection devices, measure, and run cables under the regulations in force.

WARNING!
Because the risk of explosion posed by fermentation gases escaped from the system, mixed with air is higher, necessarily all power and light installations must be made explosion proof.
It will provide facilities required earthing and lightning rod.

The heating.            
This installation is required only in stations where the temperature minimum technological + 5 º C may be provided by heat from electric motors pumps.
Heating is done by connecting the heating system of the pumping station with installation of central heating pump house.

Plumbing
Pump house is equipped with a bathroom in whose components in showers, sinks and toilets, sanitary wastewater will be discharged the group directly in the receiving basin.
       
Plant for water and sludge exhaustion
Are needed in case the drainage of low points of the station can not be done by gravity.
Drainage and sludge can be done with electro ..

Lifting Equipment
Pumps and engines will be raised or lowered in an emergency at the station for assembly using a crane monorail.

Telecommunications equipment
Mounted obligatoiru an urgent phone to transmit important information to the guard or one of servantii operating the station such as fault (failure) installation suction or discharge water from the water catchment area, announcing the fire brigade in case of fire or police announcement where criminals try to vandalize the house
