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.

· 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.

Stop running situation, when the motor is inversely proportional to the hydraulic directional valve within the operating system into position, hydraulic directional valve is inversely proportional to effect on the drawing for type O, which is closed system, the motor due to the inertia moment, is the developmental tendency of rotation, and thus in high speed hydraulic motor motor oil mouth causing a flash of high pressure (destructive) led to the working pressure, The working pressure of the hydraulic five star motor high pressure oil exceeds the linear working pressure of the speed regulating valve. According to the overflow effect of the speed regulating valve, the high pressure oil of the oil return hole of the oil motor leaks to the oil inlet of the motor according to the speed regulating valve.

Because the brake tube is closed, the oil in the motor inlet can not be filled immediately when the hydraulic motor of the crankshaft connecting rod rotates, which will lead to suction, and the working pressure oil of the oil return hole spills into the motor inlet hole. The minimum hydraulic motor can alleviate the motor suction difficulty and fill the oil inlet hole. Due to the action of pressure oil, the imbalance of bearing force causes the motor to torque. The derived torque of the hydraulic motor is related to the displacement of the hydraulic motor and the pressure difference between the inlet and outlet of the hydraulic motor and the middle of the oil inlet hole, and its reduction ratio is managed by the total flow specifications of the input hydraulic motor. Because hydraulic motors generally require positive and negative rotation, the leaves of hydraulic motors should be placed radially.
