The automated pump stations

- In detail
Operating conditions of system are defined by a technological operating mode of units. Systems of automatic control of pump units have to provide performance of all regime parameters of operation of units on the set system of water supply and water disposal at the set sequence of turning on of pumps.
The main processes which are carried out at pump stations by automatic equipment devices are:
reception and transfer of the operating impulse on start-up and a stop of pump units;
endurance of time as before start-up after receiving a command impulse, and between separate processes;
turning on of one or several pump units in the established sequence;
creation and maintenance of necessary vacuum in the soaking-up pipeline and a pump housing peredy start-up;
opening and closing of latches on pipelines at the set moments at start-up and a stop of the unit;
control of the set operating mode at start-up, work and a stop;
shutdown of the pump at violation of the set mode and turning on of the reserve unit;
transfer of parameter of an operating mode of the pump on control office;
protection of the unit against electric, thermal and mechanical damages;
control of heating and ventilation in pump station;
protection from penetration on station of strangers;
inclusion and shutdown of the drainage pumps and pumps pumping water on cooling and consolidation of epiploons of fecal pumps;
inclusion mechanized grabel.
The complex scheme of automated management of pump station usually consists of the following separate parts: schemes of automation of the gulf of the pump; schemes of automation of a latch on the pressure head pipeline; schemes of automation of the electric drive of the pump; the scheme of the interrelation which is providing sequence of action of system in general and carrying out necessary blocking, and also automatic protection of the unit and the alarm system.
