Komatsu hydraulic system parts

The Komatsu hydraulic system is the most complex and important system that ensures the operation of Komatsu equipment. The main task of the Komatsu hydraulic system and each of its individual links is the conversion of the mechanical energy of the engine into hydraulic energy necessary for the movement of the Komatsu equipment and its operability.

Komatsu Hydraulic cylinders
Komatsu Hydraulic cylinder - volumetric hydraulic motor of reciprocating motion. The principle of operation of hydraulic cylinders is largely similar to the principle of the action of pneumatic cylinders. The moving part of the Komatsu hydraulic cylinder, which may be a rod, a plunger or the cylinder body itself, performs reciprocating motion. The main parameters that characterize all Komatsu hydraulic cylinders are the internal diameter, stroke length, rod diameter and nominal working fluid pressure. Komatsu Hydraulic cylinders come in several types: piston, telescopic, plunger, two-sided and one-way. According to the type of attachment, Komatsu hydraulic cylinders are divided into models with hinged fastening and rigid fastening. Komatsu single-acting hydraulic cylinder makes effort on the movable rod, which is directed only to one side (the working stroke of the cylinder). In the opposite direction, the movable link simply moves back under the action of gravity or a return  
Komatsu Hydraulic Pumps
The Komatsu hydraulic system works as follows: The diesel engine rotates the shaft of the Komatsu hydraulic pump, which converts mechanical energy into energy hydraulic. The hydraulic fluid is piped into the Komatsu hydraulic pump and the Komatsu hydraulic cylinders through the Komatsu control valve system and converted there into mechanical energy of rotation or reciprocating motion. After performing the work, the hydraulic fluid returns to the hydraulic oil tank and enters the Komatsu hydraulic pump. The cycle of work is repeated. Exist two types of heavy equipment Hydraulic systems: A volumetric hydraulic system for its operation uses hydraulic motors and hydraulic pumps operating under high pressure up to 350 MPa. This system uses the principle of alternately filling the working chambers of the pump and the hydraulic motor with a hydraulic fluid and displacing it from there under high pressure. The speed of movement of the working fluid in such a system is small. The 
Komatsu Control Valves
When hydraulic systems are in operation, it becomes necessary to change the flow direction of the working fluid in its individual sections in order to change the direction of movement of the machine's actuators; it is required to provide the necessary sequence of activation of these mechanisms, to discharge the Komatsu pump and the hydraulic system from pressure, and so on. These and some other functions are performed by a special hydraulic device - the hydraulic Komatsu control valve. In the manufacture of Komatsu hydraulic control valves, steel castings, modified cast iron, high and low carbon steel grades, and bronze are used as structural materials. To protect individual elements of the Cat control valves from abrasive wear, sliding surfaces are cemented, nitrided and so on. The dimensions and mass of the Komatsu control valve depend on the flow rate of the liquid through which the dimensions of the unit increase. Thanks to the hydraulic system, the Komatsu machine
