Excavator Hydraulic Pump

1) Function and role of komatsu pc200 hydraulic pump

The hydraulic pump is also called the working pump, commonly known as the main pump. The hydraulic pump is an energy conversion device that converts the mechanical energy from the engine into hydraulic energy, providing

Supply a certain flow of pressure oil to drive the hydraulic cylinder and hydraulic motor, which is the power source of the entire hydraulic system.

The hydraulic pump is mainly composed of shell, cylinder block, plunger, swash plate, valve plate, slide plate, drive shaft, servo piston, PC valve, LS valve, solenoid valve and other accessories.

The specific application may be different, and the actual product shall prevail for specific use.

What should I do if the excavator walks slowly and deviates? - Check the kobelco sk60 hydraulic pump!
What should I do if the digging motor does not move and the car is seriously stuck? - Check the hydraulic pump!
What should I do if the whole vehicle of the excavator moves slowly or does not move at all when it is serious - check the hydraulic pump!

How to choose a good quality kobelco sk200 hydraulic pump? Of course, you must choose a reliable company to buy kobelco sk200 hydraulic pump. If you want to choose a hydraulic pump with good quality, you must choose a good company.

The working principle of kobelco hydraulic pump：
The hydraulic system of the excavator consists of five parts: power components, control and adjustment components, actuators, auxiliary components and hydraulic oil. The working process of the hydraulic system of the excavator is as follows: the diesel engine outputs power through the coupling, the kobelco hydraulic pump absorbs oil from the hydraulic oil tank, the working oil is output through the working pump, and the pilot oil is output through the pilot pump. After the driver manipulates the pilot handle, the pilot valve is opened, and the pilot oil pushes The main control valve spool, the working oil enters the motor or the oil cylinder, and realizes the expansion and contraction of the oil cylinder of the rotating, walking and working device.

The doosan excavator hydraulic pump is the power component of the hydraulic system, its function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of doosan excavator hydraulic pump generally include gear pumps, vane pumps and plungers.

When the hyundai 210 excavator hydraulic pump of the excavator is seriously worn, it has a fatal impact on the excavator, so such problems in the excavator must be solved in time. When repairing the hydraulic pump of the excavator, find the cause of the failure from the following three points:

Disassembly and assembly of volvo excavator hydraulic pump
Step 1: After cleaning the oil stain on the surface of the volvo excavator hydraulic pump, disassemble the hydraulic pump and place it on a clean workbench, and then remove the regulator fixed by the hexagon socket head bolt.
Step 2: Lay a rubber pad or cotton cloth on the workbench, put the pump and regulator installation side down, and place them horizontally on the workbench to disassemble the pump and valve body.
Step 3: Take out the cylinder block, plunger, valve plate, and cylinder spring from the hydraulic pump housing.
