PISTON MOTORS AND PUMPS & SPARES

Fixed Displacement Hydraulic Piston Motors & Pumps
The fixed displacement hydraulic piston motors and hydraulic piston pumps involve a pumping unit mounted in the body and a cover.

The pumping unit consists of a distributor and a hydraulic assemble including a shaft, bearings and a cylinder block. The cylinder block contacts with the distributor through a spherical surface.

The hydraulic piston pumps are produced with splined and keyed shafts, both with center clockwise and with clockwise rotation as well as with different back cover designs.

Hydraulic Piston Motors

In the motor operating mode, working fluid delivered from hydraulic system through openings in the cover and through a groove in the distributor enters the cylinder block where it sets the pistons in motion.

The pistons transfer the force to a spherical joint.

Because the shaft axis and cylinder block axis are at an angle, the force acting on the joint is resolved into an axial and a tangential component.

The axial load is taken up by bearings while the tangential one develops a torque at the hydraulic motor shaft.

This shaft torque is directly proportional to the motor displacement (V) and pressure difference (DP), its value is limited by the safety valve.

The rotational speed (n) is directly proportional to working fluid supply and inversely proportional to the displacement.

Hydraulic Piston Pumps

In the pump operating mode, the shaft is set in rotation by the engine. Pistons mounted in the cylinder block turn on the cylinder block axis and reciprocate at the same time, with the piston sucking working fluid in one half revolution and pumping it into hydraulic system in another half revolution.

The output pressure is determined by working member load and limited by hydraulic system safety valve.

The delivery rate is determined by rotational speed of the pump shaft and pump displacement.

Hydraulic Piston Pumps Type 313

The type 313 variable displacement axial-piston pumps are characterized by a wide displacement changing range and different regulation / control modes. In the initial state the displacement can be both maximal and minimal. The control can be positive or negative. The positive control increase the displacement, the negative - decrease it. Changing the displacement causes changes of delivery rate and consumed (driving) moment.

Limitation of the minimal and maximal displacements is effected by means of adjusting screws.

The design without displacement limitation (without the screws) is the basic one.

The variable displacement pumps are designated by structural diagram.

Variable Displacement Hydraulic Motors
The type 303 variable displacement reversible axial-piston hydraulic motors (hereinafter referred to as hydraulic motors) are characterized by a wide displacement range and different regulation / control modes.

In the initial state the displacement can be both maximal and minimal. The control can be positive (increasing the displacement) or negative (decreasing it.)

The rotation direction, torque, and rotational speed of the hydraulic motor shaft are determined by the supply direction, pressure and displacement of the hydraulic motor itself.

The displacement is determined by the piston diameter and cylinder block bending relative to the shaft axis.

The angle between the shaft axis and cylinder block axis can be changed both automatically by operating pressure in hydraulic system and by external control system with obtaining necessary characteristics.

Limitation of the minimal and maximal displacement is effected by means of adjusting screws.

The design without displacement limitation (without the screws) is the basic one. The adjustable hydraulic motors are designated are by structural diagram
