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.

The design of hydraulic press motor reducer system software should pay attention to the difficulties:

1. In the formation of the usual control loop, it is necessary to pay attention to prevent the harm between the control loop and ensure the normal business process cycle.

2. Improve the working efficiency of system software and prevent system software from overheating. For example, the power is small, you can use one-way throttle speed control system software; Power, Z powerful volume speed control system software; Often stop the brake system, should make the pump can relieve pressure as soon as possible; In each work cycle in the oil consumption rate difference is quite large system software, hydraulic press screw drilling rotary table manufacturers should fully consider the disc brake hydraulic motor accumulator or pressure compensation variable pump and other high efficiency control loop.

3. To prevent the damage of the hydraulic machine, for the system software with high pressure and large flow, the hydraulic valve should be fully considered to replace the electro-hydraulic valve with the hydraulic valve to ease the ball plug hydraulic motor commutation speed; Choose energy storage device or add cache file control loop to eliminate the damage of hydraulic press.
