Generally, rolling bearing or hydrostatic sliding bearing, hydraulic special-purpose Cycloidal motor of overhead crane Since the pressure motor works under the condition of input pressure oil, it does not need to have self-priming capacity, but it needs to have a certain initial air tightness to provide the necessary starting torque. The existence of these differences makes the structure of the hydraulic motor and the hydraulic pump relatively close, but they cannot work reversibly. The classification of hydraulic motors can be divided into gear type, impeller type, plunger type and other types according to the structure type. According to the rated speed of the hydraulic motor, it can be divided into high speed and low speed. The rated speed exceeds 500r/min Yulin Cycloidal motor of overhead crane High speed hydraulic motor, while the rated speed is lower than 500r/min, it belongs to low speed hydraulic motor.

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 special-purpose Cycloidal motor of overhead crane 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. Yulin Cycloidal motor of overhead crane 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.

As a kind of hydraulic transmission device, hydraulic motor has been widely used in many places. In fact, I have seen it on many occasions. The main application fields are. 1. The hydraulic motor has convenient speed regulation, which can be adjusted infinitely from 0 to the maximum speed according to the adjustment of the hydraulic valve. The motor itself does not need special design and has low cost. This is much cheaper than motor+reducer, or variable frequency motor and servo motor. 2. The hydraulic system has strong anti overload capacity and relies on the overflow valve for protection, allowing a long time special-purpose Cycloidal motor of overhead crane (Relatively) Frequent overload, easy to recover under overload, no damage to equipment, no restart of equipment. 3. The hydraulic system is characterized by high energy density. For motors of the same power, hydraulic motors are much smaller than motors Cycloidal motor of overhead crane Price , much lighter. And it is easy to apply to mobile devices. 4. The hydraulic motor is totally enclosed and can be safely used in dusty, wet (even underwater) and flammable environments, which is much more reliable than explosion-proof (flameproof) motors.

The manufacturer of the hydraulic motor has explained to us the relevant knowledge about the speed and low-speed stability of the hydraulic motor. The speed of the hydraulic motor depends on the flow of the supply fluid q and the discharge of the hydraulic motor itself v. The hydraulic motor has internal leakage. Not all the liquid entering the motor drives the hydraulic motor to work. Some of the liquid is lost due to leakage, and the actual speed of the motor is lower than the ideal situation. When the working speed of the hydraulic motor is too low, it cannot maintain a uniform speed, and it stops when entering Yulin Cycloidal motor of overhead crane The unstable state is a creeping phenomenon. The high-speed hydraulic motor is required to work at a speed below 10r/min and the low-speed high torque hydraulic motor is required to work at a speed below 3r/min. All hydraulic motors can meet the requirements. Generally speaking, the low-speed stability of low-speed large torque hydraulic motors is better than that of high-speed motors. Due to the large emissions and size of the low-speed high torque motor, the sliding speed of the friction pair will not be too low even if the rotation speed is low special-purpose Cycloidal motor of overhead crane Large emissions, relatively small impact of leakage, large rotation inertia of the motor itself, easy to obtain good low-speed stability.

The hydraulic motor is usually put into operation Yulin special-purpose Clean before use. The purpose of cleaning is to remove the pollutants, metal chips, fiber compounds and iron cores left in Madai. In the first two hours of operation, even if the motor is not completely damaged, there will be a series of failures. Therefore, the hydraulic motor oil circuit should be cleaned as follows: 1. Clean the oil tank with easy drying cleaning solvent, and then remove the solvent residue with filtered air. 2. Clean all pipes of hydraulic motor. In some cases, it may be necessary to impregnate pipes and joints. 3. Install an oil filter on the pipeline to protect the oil supply pipeline and pressure pipeline of the valve. four special-purpose Cycloidal motor of overhead crane Install a flushing plate on the collector to replace precision valves, such as electro-hydraulic servo valve. 5. Check whether all pipes are of proper size and connected correctly.

At present, in the hydraulic system of construction machinery, the commonly used oil change method is by cycle or by train number. The hydraulic system of some construction machinery requires that the hydraulic oil be replaced when the motorcycle is 1200. surface special-purpose Cycloidal motor of overhead crane Grid 6 has reference value. For the maintenance of the hydraulic system, the parameters in Table 7 of the used hydraulic oil can better explain the problem. If the three items in Table 7 generally exceed the limit, the hydraulic oil shall be replaced. Except that the solid particles exceed the limit, that is, the hydraulic oil shall be replaced if the solid particles exceed the limit. During field inspection of oil, empirical inspection shall be carried out first, and whether to continue quantitative inspection shall be determined according to the observed oil pollution. According to the test results, determine the solution Cycloidal motor of overhead crane Price What measures shall be taken for oil pressure (half oil change, full oil change or filtration). Thus, the quality of hydraulic oil in the hydraulic system can be guaranteed, so as to reduce system failures and improve the reliability of the system.
