PUMP STATION AUTOMATION
The operation of pump stations is a multi-task procedure that ensures the station’s performance and the safety of equipment & personnel at a minimum cost. The operation of the pump station, in some mines, has not changed for decades and it becomes less and less affordable. In fact, most mines that have automated their pump stations, did it by applying expensive technology, which provided the necessary functions at high capital cost and with great dependency on high-tech qualified personnel.
The aging of the pumping systems, the declining of skilled personnel and the demographic changes in the country demand a new approach to the method of operating pump stations. Therefore, the automation of the pump station operation will achieve a significant reduction in the running and maintenance costs of the pump station.
PRINCIPALS OF OPERATION
The Hydrocore™ Pump Discharge Control Valve is a new and innovative application of the Hydrocore™ valve series and combines three basic principles of the Hydrocore™ valve series. The unique features of our valve are:
Opens automatically on pump startup as a result of the pump's discharge pressure acting on valve's shuttle.
Prevents pump surge conditions by maintaining a positive discharge pressure when the pump is running, irrespective of the discharge column fullness level.
Closes automatically on pump stop as a result of the valve’s top compartment force, acting on the valve's shuttle, against the pump's reduced discharge pressure.
Assists Hydrocore™ check valve on the pump's discharge.
Can prevent water hammer on pump trip or pump stop occurrences by utilizing an Hydrocore™ check valve.
Prolongs the balancing disc life span by maintaining a positive discharge pressure when the pump is running, irrespective of the discharge column fullness level.
The pump discharge valve can also be electrically actuated (instead of pneumatically actuated).
