Triple Hydraulic Pump
Triple Hydraulic PumpDue to the structural limitations of the fixed displacement, it is generally believed that the gear pump can only be used as a constant flow hydraulic source.
Installing the control valve directly on the triple hydraulic pump can save the pipeline between the pump and the commutator valve, thus controlling the cost. Reduce the leakage of pipe fittings and fittings and improve the reliability of the work. The valve installed by the pump itself can reduce the pressure of the circulating circuit and improve its performance.
Because the liquid constant displacement structure of gear pump is limited, it is generally believed that the three-cylinder hydraulic pump can only be used as a constant flow hydraulic source. However, the secondary threaded valve combination scheme can effectively improve its function, reduce the system cost, improve the reliability of the system, so that the performance of the gear pump is close to the expensive and complex piston pump. At this point, the large flow pump will flow from its outlet cycle to the inlet, thus reducing the flow of the pump to the system output, so that the pump power is reduced to slightly higher than the high pressure part of the required work value.
