Abstract
A load sense pump can be used as a backup for a pressure-compensated pump in a wellbore operation. A pumping system can include a first pump, a second pump, a check valve, and a directional control valve. The first pump, which can be a load sense pump, can be used to provide pressure to a first hydraulic load. The second pump, which can be a pressure-compensated pump, can be used to provide pressure to a second hydraulic load. The directional control valve can be controllable to cause the first pump to change operation to provide pressure to the first hydraulic load and through the check valve to the second hydraulic load.
Claims17
A pumping system comprising:
- a first pump to provide pressure to a first hydraulic load;
- a second pump to provide pressure to a second hydraulic load;
- a check valve;
- a directional control valve that is controllable to cause the first pump to change operation to provide pressure to the first hydraulic load and, through the check valve, to the second hydraulic load;
- a computing device;
- and
- a non-transitory computer-readable medium that includes instructions that are executable by the computing device to:
- determine an output pressure level of the second pump, the output pressure level being measureable by a pressure transducer, the pressure transducer being communicatively couplable to the computing device;
- and
- transmit an electrical signal to the directional control valve to cause the first pump to change operation in response to the output pressure level of the second pump.
A flow distribution manifold comprising:
- a check valve;
- a directional control valve that is controllable to cause a first pump to change operation to provide pressure to a first hydraulic load and through the check valve to a second hydraulic load, wherein the first pump is configured to provide pressure to the first hydraulic load prior to the operation change and a second pump is configured to provide pressure to the second hydraulic load prior to the operation change, wherein the directional control valve is communicatively couplable to a computing device, the computing device being communicatively couplable to a non-transitory computer-readable medium that includes instructions that are executable by the computing device to:
- determine an output pressure level of the second pump, the output pressure level being measureable by a pressure transducer, the pressure transducer being communicatively couplable to the computing device;
- and
- transmit an electrical signal to the directional control valve to cause the first pump to change operation in response to the output pressure level of the second pump.
A method comprising:
- providing, by a first pump, pressure to a first hydraulic load;
- providing, by a second pump, pressure to a second hydraulic load;
- controlling a directional control valve to cause the first pump to change operation to provide pressure to the first hydraulic load and, through a check valve, to the second hydraulic load;
- providing, by the first pump, pressure to the first hydraulic load and through the check valve to the second hydraulic load;
- measuring, by a pressure transducer, an output pressure level of the second pump;
- receiving, by a computing device, the output pressure level of the second pump from the pressure transducer;
- and
- transmitting, by the computing device, an electrical signal to the directional control valve to cause the first pump to change operation in response to the output pressure level of the second pump.
