D1146 65.02501-0507 Sleeve Cylinder Kit , DOOSAN DH300-5 DH300-7 Piston Ring Set

Complete Variety Piston Liner Kit for DOOSAN DH300-5/DH300-7 D1146 65.02501-0507

OPERATING PRINCIPLE:

The cylinder sleeve is a cylinder -shaped part, placed in the body hole of the body, and the upper is pressed and fixed by the cylinder head. The piston is cooled in the inner hole, and it has cooling water cooling outside.

The function of the cylinder set is:

1. Together with the cylinder head and the piston, it forms a cylinder working space.

2. The cylinder sleeve of the piston -shaped piston is the piston side thrust, which has become a guide for the piston to reciprocate.

3. Pass the piston component and its own heat to cooling water, so that the working temperature is appropriate.

The cylinder sleeve of the two -stroke diesel engine has a air mouth, which is closed from the piston to achieve gas distribution.

EXCAVATOR MAINTENANCE METHOD

Trouble: Excavator Weak

Solution: The powerlessness of the whole machine can be divided into several aspects. First, the engine decelerates sharply when the external load is large, which is manifested in the following two aspects:

1. Check the engine power first as mentioned above.

2. It is to check whether the hydraulic displacement follows the constant power output. That is, on the premise of not affecting the speed, adjust the angle of the swash plate to reduce the displacement. The second is that the engine does not decelerate when the load is heavy, and the system speed is normal; this requires debugging the system pressure, because the hydraulic components used by each manufacturer are different from the hydraulic system. The specified hydraulic cylinder pressure is also different, as long as the manufacturer It is enough to specify the standard debugging. In addition, if the pressure of the relief valve cannot be adjusted up, and check that the relief valve is in good condition, it is necessary to check the adjustment system of the hydraulic pump, and even the cylinder, distribution plate, plunger and other components of the hydraulic pump.
