Regulators introduction Code Control Type Function and Features Hydraulic circuits L (L1) 1. Load sensing function tandard setting: 15bar Adjustment range:1bar~21bar 2. ressure cut-off function tandard 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 bleedoff orifice in the external valving to prevent trapped pressure. ump Flow ressure Lode ense and ressure Cut -off The load sensing control is a flow cotrol option that operates as a function of the load pressure to regulate the pump displacement to mach 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 p) and with it the pump flow constant. If the differential pressure p increases, the pump is swivelled back (towards Vmin), and if the differential pressure p decreases, the pump is swivelled out (towards Vmax) until the pressure drop across the sensing orice in the valve is restored. p=pp-pa ump displacement is controlled to match the flow requirment 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 setpoint set at the intergral pressure control valve, the pump displacement is antormatically swivelled back until the pressure deviation is corrected.

Remote Control The pump can be remotely controlled by connecting a relief valve to the L port of the regulator. The pump can also be unload to opterate at a low pressure standby condition by using a solenoid valve L R3 R1 Differential ressure pool Cut-Off ressure pool R2 f ressure f R2 are optional the standard configuration without R2. 3

In response 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 gererated by the system pressure. By turning an outer and inner spring adjustment screw, the appropriate input torque limit can be set.

Caution for using 1. Mounting Direction and Drain iping Installation Type Caution ketch Diagram 1) Mount the pump with shaft directed horizontal; 2) The drain piping must be arranged above the top of the pump case and led to tank directly; Horizontal Installation 3) The upper drain port should be used, and the drain piping size must be equal to or larger than the drain port size ; 4) The suction line must be arranged above the top of the pump case between the pump and oil tank. Maximum mounting height above the oil level is 1m and suction pressure should be -.1Ma and above. Within 1m Min. oil level Installation within a tank 1) Open the drain port and the air bleeder plug port. Vertical installation ipe for air bleeding Installation outside a tank 1) ipe the drain port and the air bleeder plug port to tank; 2) If the pipe for draining or air bleeding is upper than the oil level (figure (a) below), the pipe should be filled with oil before starting the pump.

HYDRAULIC COMONENT Caution for using 2. Filtration 1)For satisfactory service life of these pumps in application, the operating fluid should be continuously filtered to keep at least the cleanliness level IO/DI 18/15 or NA1638 Class9; 2)A 1μm-filter must be used in the return circuit and an 8~15-mesh strainer in the suction circuit. 1μm 15 mesh 1) Use a flexible coupling for connection of the pump drive shaft with an engine flywheel; a 2) Alignment should be so carried out that the parallel error may be held within ±.25mm; Engine δ ump 3. Connection of driving shaft 3) Do not put radial or axial load at the shaft end; 4) Use screws and thread for fixing the coupling without hammering; 5) The acceptance standard of alignment arallel misalignment δ.25mm (Dial gauge reading a= below.5mm) Angular misalignment α.2deg Dial gauge (reading a) δ =a/2 Engine Dial gauge (reading b) α=in -1 (b/d) ΦD b α ump 4. Fluid It is recommended to use the anti-wear type hydraulic fluid as mineral oil type when the pressure is higher than 2.6Ma. 5. tarting 1) Before starting-up, fill the pump case with system fluid through the case drain connection. Case must remain full of fluid to provide internal lubrication; 2) At starting, the hydraulic circuit should be in the unload condition. max 4bar 6. Case drain pressure lease be careful so that the drain pressure in the casing does not exceed.1 bar normally and.4 bar at its peak. A suitable size of drain hose and drain filter should be selected. normal 1bar.1 t 36
