6 6/32 Hengli hydraulic Regulators introduction Code: L (L1) 1 Control Type : 1. Load sensing Standard setting:15bar Adjustment range:1bar-21bar 2. Pressure Cut-off Standard setting:32bar Adjustment range:21bar-32bar L1 option(difference from L) With the L1 option, the bleed off orifice(r4)is plugged, when this option is applied, there must be another bleed off orifice in the external L (L1) valving to prevent trapped pressure. Pump flow Pressure Function and Features: Load sensing+ Pressure Cut-off The load sensing control is a flow control option that operates as a function of the load pressure to regulate the pump displacement to match the actuator flow requirement. The load sensing control compares pressure before and after the sensing orifice and maintains the pressure drop across the orifice (differential pressure Δp) and with it the pump flow constant. If the differential pressure Δp increases, then the pump displacement decreases, and if the differential pressure Δp decreases, then the pump displacement increases until the pressure drop across the sensing orifice in the valve is restored. Δp=Pp-Pa Pump displacement is controlled to match the flow requirement as a function of the system differential pressure(load pressure vs delivery pressure).in addition, there is a pressure cut off function incorporated into the control. The pressure cut off control keeps the pressure in a hydraulic system constant within its control range even under varying flow conditions. the variable pump only moves as much hydraulic fluid as is required by the actuators. if the operating pressure exceeds the set point set at the pressure control valve, the pump displacement is automatically swivelled back until the pressure deviation is corrected.

Pump flow 1 Remote Control The pump can be remotely controlled by connecting a relief valve to the PL port of the regulator.

Pressure Cut-off Standard setting: 32 bar Adjustment range: 21 bar-32 bar 3. Torque limiting Pump flow Pressure Function and Features: _/1 Load Sense and Pressure Cut-off with Torque limiting The L/L1 control functions as previously noted. In response /1 to a rise in delivery pressure the swash plate angle is decreased, restricting the input torque. This regulator prevents excessive load against the prime mover. The torque limit control module is comprised of two springs that oppose the spool force by the system pressure. By turning an outer and inner spring adjustment screw, the appropriate input torque limit can be set. Torque limit control valve Hydraulic Circuit: PL LS valve R4 R1 Cut-off valve P T1 T2 S /1 8

11 Hengli hydraulic 11 /32 Regulators introduction Code: *-ED* or ED* Control Type : The displacement of a variable displacement pump can be adjusted via an electro-hydraulic proportional adjustment. Control current range is Displacement 1 ca. 3 ma to ca. 8 ma(24vdc) or ca.6ma to ca.16ma(12vdc) MIN MAX Current I(mA) Function and Features: Electric proportional displacement The main pump is supplied with servo pressure /ED via port St as soon as the servo pump is started. The solenoid is usually deenergized during start of operation, i.e. the valve piston is pushed against its stop by the metering spring. This opens a passage to the larger area of the piston which returns the swash plate to its idle position. There is always pressure apparent at the smaller side of the control piston. When the solenoid is energized with 3 ma (24VDC-solenoid) or 6 ma (12VDCsolenoid) it will push the valve piston against the spring force thereby connecting the larger area of the control piston with the tank. The control piston will move the swash plate against the metering spring in direction of increased delivery flow and loading the metering spring. This movement will stop as soon as the forces of the metering spring and the proportional solenoid are balanced thereby closing the prop. valve. Both total delivery flow and total stoke of the solenoid are achieved when the solenoid is energized with 8 ma (24VDC-solenoid) or 16 ma (12VDC-solenoid). Use electro-proportional displacement control valve and swash indicator can realize the close circuit control of the pump. Hydraulic Circuit: MA 4~6bar St P X T2 S T1 /ED 11
