Hydraulics kalkfilter on excavator includes some details following: hydraulic oil tank, hydraulic pump, valve and other major distribution control valves, motors swing, move motors, hydraulic cylinders power, pipelines, hydraulic oil filter, hydraulic oil cooler safes.
Working principle When the engine (1) work. The power is transmitted through the flywheel to the hydraulic pump. Hydraulic pump (2) work, sucking oil from the oil tank and pushed kalkfilter to the main distribution valve (8). On the cab the operator will affect the joystick device works, swing, move. When the impact of the operator a control oil flow will be open to go to the main distribution valve. Oil flow control will take effect on / off valve corresponding distribution for the work equipment, swing, move. The main oil line to the cylinder (7) should, bucket or the bucket arm. Such devices can work to work the will of the operator. Road motor oil go to swing (5) or motor movement (3) makes the motor rotates. Motor will rotate or drag pull carriages through the drive chains and pie late star makes the car move. Road before the barrel of oil is cooled in a safe, cool, filtered water and dirt in the hydraulic oil filter. The pressure of the hydraulic system is limited by safety valve, usually mounted in the valve distributor. When the system pressure reaches the limit of the valve, the valve opens and the flow of oil barrels. Hydraulic pump and the motor speed control system of hydraulic excavators usually have 02 primary piston hydraulic pump (6), (8), an oil pump control (7) type gear. On the large-capacity excavators have added a separate cooling hydraulic kalkfilter circuit, they often have more oil pumps, hydraulic piston cooling fan circuit. The output of the pump, system pressure, engine speed intimately linked together in the process of work and they are controlled kalkfilter via the control box and motor pumps (1). During regular working black box control input signals from: Scooter (11) screens (12), two sensor output pressure of the pump (9), the sensor station (2), left variable speed motor (5). Through that black box (1) sends a control signal to the speed regulator (3) to control the motor speed. Send control signals to solenoid ratio (10). Control oil flow from the oil pump control (7) passes through the electromagnetic valve control ratio to disc tilt angle of 02 to open the hydraulic pump main. This allows control of pump output matching workload and capacity of the engine. Hydraulic system to work well, all the details of the hydraulic system should kalkfilter be in good technical condition. The input signal and the output signal of the control box (1) shall be within the manufacturer's standards.
