When the working load changes from low speed to high speed in a wide range, the hydraulic motor is also required to be able to drive and regulate speed in the corresponding wide range, which requires the motor to have good low-speed stability and high speed performance. The speed regulation range K of the hydraulic motor is usually expressed by the ratio of the allowable maximum speed to the minimum speed. want to buy M+S cycloidal motor It is the highest operating speed of hydraulic motor, but it is limited by many factors, mainly including: 1. Service life. After the speed increases, each pair is worn Fuyang Manufacturer The service life is shortened. 2、 Mechanical efficiency limits. At high speed, the hydraulic motor needs to input large flow, accordingly, the hydraulic loss of each circulating component increases, reducing the mechanical efficiency.

As the power source and actuator of the hydraulic system, the performance of the hydraulic motor has a great impact on the performance of the entire hydraulic system. Therefore, the importance of studying the hydraulic motor performance test system is want to buy M+S cycloidal motor It is very important that the rise and application of hydraulic testing technology based on virtual instrument has opened up a broad prospect for the performance testing of hydraulic motors. Hydraulic motors are widely used in machine tools, metallurgy, engineering machinery, plastic machinery, agricultural machinery, mining machinery, marine machinery and many other important fields. The performance of the hydraulic motor has a decisive impact on the whole system, and will directly affect the stability of the system. At the same time, the performance of the hydraulic motor will have an impact on the life of the system components and the production efficiency of the system. Fuyang Manufacturer Unexpected failure of hydraulic motor will greatly reduce production efficiency.

Most of its hydraulic system uses working medium, such as hydraulic oil with continuous fluidity, which converts the mechanical energy of the prime mover driving the pump into the pressure energy of the liquid through the hydraulic pump, and sends it to the actuator (hydraulic cylinder, hydraulic motor or swing hydraulic motor) through various control valves, such as pressure, flow, direction, etc., to convert it into mechanical energy to drive the load. This hydraulic system is generally composed of the following parts: power source, actuator, control valve, hydraulic auxiliary device and hydraulic working medium, which play their respective roles: power source: prime mover (motor or internal combustion engine) and hydraulic pump, whose role is to convert the mechanical energy generated by the prime mover into the pressure energy of liquid, and output oil with a certain pressure;

Cycloidal hydraulic motor structure: the internal meshing gear pair consisting of rotor and stator, cycloidal needle wheel, as the meshing pair, has a torque generating part. The stator, together with the spacer and the rear cover, is fixed on the housing to form seven cavities that are only connected with the oil holes on the housing one by one. A distribution mechanism consisting of an oil distribution sleeve and a housing. Two oil distribution sleeves Fuyang M+S cycloidal motor The ring groove is respectively connected with the oil inlet and return ports of the housing, and its longitudinal groove has twelve oil ports, M+S cycloidal motor Manufacturer Six oil ports and the oil distribution hole of the housing form the oil distribution link. The splines at both ends of the linkage shaft are respectively connected with the rotor and the output shaft, which is used to transmit torque and ensure that the oil sleeve is synchronized with the output shaft. The function of the output shaft is to output the torque generated by the rotor through the linkage shaft and drive the oil distribution device to rotate synchronously.

1. Pascal principle: also known as static pressure transmission principle, it refers to the pressure exerted on the static liquid in a closed container is transmitted to all points of the liquid at the same time with equal value. The hyperbolic cosine of 2. The hyperbolic cosine of 2. System pressure: the discharge pressure of the hydraulic pump in the system. The hyperbolic cosine of 3. The hyperbolic cosine of 3. Servo valve and proportional valve: infinitely adjust the output of hydraulic valve, such as pressure, flow and direction, by adjusting the input electrical signal analog quantity. (Servo valve also has pulse want to buy M+S cycloidal motor Wide modulation input mode). But the structure of these two valves is completely different. The servo valve controls the work of the torque motor by adjusting the electrical signal to deflect the armature and drive the front valve to work. The front valve control oil enters the main valve and drives the valve core to work. The proportional valve regulates the electrical signal to make the electric iron shift, drive the pilot valve core, drive the control oil generated, and drive the main valve core. The hyperbolic cosine of 4. The hyperbolic cosine of. Fuyang M+S cycloidal motor Kinematic viscosity: the ratio of dynamic viscosity μ to the liquid density α. The hyperbolic cosine of 5. The hyperbolic cosine of 5. Fluid power: the force exerted by the flowing liquid on the solid wall to change the flow velocity.

Precautions during operation of cycloidal hydraulic motor: before operation, check whether all parts of the hydraulic system are connected correctly, and inject oil into the specified Fuyang M+S cycloidal motor Height. Start and run without load for 10-15 minutes, and exhaust. Air bubbles in the oil tank, noise in the system, and gas accumulation in the engine oil cylinder all prove that there is air in the system. After the gas is discharged, fill the oil tank, and then gradually increase the load of the motor until the load is too large. Observe whether there is noise, oil rise, oil leakage and other abnormal phenomena. After 50 hours of operation, change the oil according to the maintenance rules, and then the oil according to the maintenance rules Fuyang Manufacturer Replace. If there is no motor fault, do not disassemble it easily.
