Caterpillar hydraulic system parts

The Caterpillar hydraulic system is the most complex and important system that ensures the operation of Caterpillar equipment. The main task of the Caterpillar 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 Caterpillar equipment and its operability.

Caterpillar Hydraulic cylinders
Caterpillar 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 Caterpillar hydraulic cylinder, which may be a rod, a plunger or the cylinder body itself, performs reciprocating motion. The main parameters that characterize all Caterpillar hydraulic cylinders are the internal diameter, stroke length, rod diameter and nominal working fluid pressure. Caterpillar Hydraulic cylinders come in several types: piston, telescopic, plunger, two-sided and one-way. According to the type of attachment, Caterpillar hydraulic cylinders are divided into models with hinged fastening and rigid fastening. Caterpillar 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 
Caterpillar Hydraulic Pumps
The Caterpillar hydraulic system works as follows: The diesel engine rotates the shaft of the Caterpillar hydraulic pump, which converts mechanical energy into energy hydraulic. The hydraulic fluid is piped into the Caterpillar hydraulic pump and the Caterpillar hydraulic cylinders through the Caterpillar 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 Caterpillar 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 suc 
Caterpillar 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 Caterpillar pump and the hydraulic system from pressure, and so on. These and some other functions are performed by a special hydraulic device - the hydraulic Caterpillar control valve. In the manufacture of Caterpillar 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 Caterpillar control valve depend on the flow rate of the liquid through which the dimensions of the unit increase. Thanks to the hydraulic system, the
