The main business of komatsu pc300 hydraulic pump are: komatsu pc300 hydraulic pump, distribution valve, self-pressure regulating valve, pilot valve, valve block, rotary reducer, rotary motor, rotary solenoid valve group, Komatsu hydraulic oil tank, hydraulic pump assembly, hand oil pump, distribution Valve assembly, grease fitting, rotary reducer, rotary reducer assembly, Komatsu series oil cylinder assembly, hydraulic pump nine-hole disc, etc. The komatsu pc300 hydraulic pump sold by the company have many varieties and specifications. The main function of the Komatsu hydraulic parts is to drive the driving power and working power of the machinery. The structure of the Komatsu hydraulic parts is cumbersome and complicated. The company generally adopts rolling bearings or static pressure. Manufactured by sliding bearings, Komatsu hydraulic parts can only be started mechanically when they are in operation. The rotational inertia of Komatsu hydraulic parts is small, it is more convenient to start and brake, and its adjustment and reversing sensitivity is high.

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. 2) Applicable models: PC200-8M0, PC200LC-8M0, PC210-8M0, PC210LC-8M0; HB205-1, HB205LC-1, HB215-1, HB215LC-1, HB205-1M0.

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.
