Load sensing refers to the variable control mechanism in which the system can automatically transmit the signal of pressure and flow change required by the load to the load sensitive valve load sensitive pump, so that its flow rate changes. Make it almost only provide the system with the required flow, minimize pressure and flow loss.
Load sensing control can automatically adapt the output pressure and flow rate of the pump to the load demand and greatly improve the efficiency of hydraulic system. Its energy saving effect is remarkable, the flow control precision is high, and it is not affected by the change of load pressure. In order to ensure the normal operation of the system, the pump pressure can only be adapted to the maximum load pressure, but when the required flow rate exceeds the limit of the pump oil supply capacity, The speed of the actuator in the maximum load loop will decrease quickly until it stops.
