As one of the "three major parts" (engine, cat 330 hydraulic pump, distribution valve) of an excavator, the "cat 330 hydraulic pump" can be regarded as an energy conversion device more often, which converts the mechanical energy from the engine into hydraulic energy, for The hydraulic system provides a certain flow of pressure oil to drive the hydraulic cylinder and hydraulic motor. It can be said that the hydraulic pump is the power source of the entire hydraulic system.

cat 320 excavator hydraulic pump Adjustment Method 1. The adjustment method of the maximum flow of the cat 320 excavator hydraulic pump: According to the figure, we need to loosen the regulator lock nut 1 first, and adjust the screw 2 at the same time. Remember to adjust the direction of adjustment clockwise to increase the flow, and anti-clockwise to reduce the flow. During the adjustment process, it should be noted that when adjusting the maximum flow, the adjustment screw 2 should not be larger than 2 turns.

The cat 312 hydraulic pump is supplied with oil by the main pump driven by the engine. The main pump is divided into an upper pump and a lower pump, both of which are swash plate type plunger pumps. There is a main pump regulator behind each main pump. By changing the effective stroke of the plunger to the main pump, the displacement increases or decreases, that is, the power absorption capacity of the main pump is increased or decreased.

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.

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!

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.
