STFC series hydraulic motors are based on the advantages of static pressure balance of crankshaft and connecting rod type hydraulic motors at home and abroad, through continuous test, improvement and improvement. This series motor shell has high strength and large bearing capacity of internal dynamic components. Due to the form of static pressure balance, internal friction is reduced, thus reducing heat generation and associated negative effects.

STFC series hydraulic motors can be widely used in the hydraulic transmission system of plastic machinery, ship deck machinery, mining construction machinery, lifting and transportation equipment, heavy metal treatment machinery, oil and coal mining machinery, machine tools, light industry equipment, drilling and other machinery. Especially used in screw drive of injection molding machine, lifting capstan, drum drive, drive of various rotary machinery and other transmission machinery.

Product features

· Due to the design of static pressure balance of plunger, connecting rod and eccentric sleeve, the friction force between connecting rod and eccentric sleeve and the lateral force of plunger body are reduced, and the contact specific pressure of ball hinge pair is reduced, which all reduce the friction loss in the transmission process. Therefore, STFC series hydraulic motors have the characteristics of high mechanical efficiency and high starting torque (mechanical efficiency above 0.90 when starting);

· The axial valve with static pressure balance technology prevents the tilt of the valve, has good sealing performance and less leakage, and can work continuously under high pressure (higher pressure up to 29MPa);

· The sealing ring adopts special material and structure to reduce leakage and improve volume efficiency;

· The main transmission parts of the motor adopt special materials and advanced heat treatment process to improve the overall service life;

· The shape and installation size of this series of motors are basically the same as the original Staffa, and the performance parameters are similar to the original Staffa, so it is the ideal choice to replace the imported Staffa motors.

JQHS series pneumatic winch is powered by pneumatic motor, through the gear reduction mechanism to drive the drum, the miniature cycloid hydraulic motor to achieve heavy weight traction and lifting winch device. It has the advantages of compact structure, convenient operation, safe and reliable work, simple maintenance, smooth operation and stepless variable speed. As explosion-proof traction, lifting power device, especially suitable for oil field (including ocean), geological drilling, mining and explosive, flammable gas and other places. Swing cylinder type hydraulic motor is the same.

Radial oil motor basic elements, when the working pressure oil through the fixed oil distribution shaft 4 prompt box into the bottom of the cylinder body plunger pump, the plunger pump extends outward, dead against the motor stator wall, because the motor stator and engine cylinder there is a eccentricity. In the contact between the piston pump and the motor stator, the reaction force of the motor stator on the piston pump is and 2 interaction forces.

When the role of the piston pump at the bottom of the gear oil working pressure is P, the piston pump diameter and the Angle between the middle of the engine cylinder caused by a distance, the engine cylinder rotation. The engine cylinder is then driven by the shaft connected by the internal thread outward to derive the pitch and reduction ratio.
