Abstract
A charging unit, system and method are provided. The system includes an activation unit and a charging unit. The activation unit includes a pump unit, a pressure circuit with an unloader valve to selectively permit fluid to pass from the pump unit to the wellsite component, and an accumulator bank operatively connectable to the pressure circuit to store the fluid under pressure for passage to the wellsite component whereby the wellsite component is selectively activated. The charging unit includes a charging circuit operatively connectable to the pressure circuit to selectively receive the fluid from the pump unit, a charging accumulator operatively connectable to the charging circuit to store the fluid under pressure, and a pressure reducing valve operatively connectable to the charging circuit to selectively pass the fluid from the charging accumulator to the accumulator bank whereby an activation pressure of the fluid provided to the wellsite component is maintained.
