Excavator loader accessories XKBF-01293 relief valve

1. Main hydraulic circuit
The main hydraulic circuit is composed of suction circuit, output circuit, oil return circuit and player circuit. Hydraulic system
Main pump, control valve, travel motor and four hydraulic cylinders.
Main pump is inclined shaft displacement variable axial piston pump, is driven by the engine (engine speed ratio of 1.0)
2. Attraction loop and output loop
The pump attracts the oil from the hydraulic tank through the suction filter, and the oil flows from the pump into the control valve and then is discharged through the tank port
The oil released by the main pump flows to the actuators through the control valve.
The control valve controls a variety of hydraulic press energy, and the return oil flowing from each actuator passes through the control valve and the hydraulic oil cooler
Flow back to the hydraulic tank.

3. Return oil circuit
The oil from each actuator flows back into the hydraulic tank through the control valve. Bypass bill in oil return circuit
In the direction of the valve, the set pressure of 9.8x1084P and 4x9.8x104PA ® normal return oil are cooled by hydraulic oil
The regulator and the left control valve flow back to the hydraulic tank,
When the oil temperature is low, the viscosity becomes higher, and the resistance through the oil cooler also increases.
The oil pressure is more than 9.8x1084 Pa inch, and the return oil flows directly back to the hydraulic tank, which can raise the oil temperature in a short time
Get to the right height.
