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;

In order to meet the needs of national economic development, hydraulic technology will continue to develop rapidly and be widely used in various industrial sectors. Therefore, vigorously developing the hydraulic machinery industry is also customized Low speed high torque cycloidal hydraulic motor In order to revitalize the development of the machinery industry. Based on improving the technical level of basic parts, we will increase the strength of technological innovation, supplemented by policy support, and fundamentally improve the technical level to achieve industrial development. On the other hand, it also shows that the development of hydraulic press in China has entered a new stage, and the development level of heavy equipment represents Low speed high torque cycloidal hydraulic motor manufactor The engineering technology level of a country. Therefore, in general, the prospect of hydraulic press in China will be better and better.

The hydraulic motor manufacturer explains to you the reasons for the poor performance of the hydraulic motor: 1. First of all, according to the analysis of the causes of the wear of the port plate, the main reasons for the weakness of the hydraulic motor are: because the port plate is worn, the oil inlet channel and the oil return channel are connected at the port plate, part of the high-pressure oil leaks, the oil pressure flowing through the stator and rotor pair decreases, and the flow decreases, Eventually, the output speed and torque of the motor will decrease. 2. Due to the wear of the valve plate, its relative position in the valve body has changed Low speed high torque cycloidal hydraulic motor manufactor The preload and adhesion of the spring on the valve body between the valve plates will be reduced, which will intensify the leakage of hydraulic oil and lead to the decline of the performance of the hydraulic motor. 3. With the increase of hydraulic oil temperature, its comprehensive performance declines, driving the cycloidal rotor to rotate Zhongshan manufactor The ability to move is further reduced. Upon inspection, there is no obvious wear on the joint surface of the stator and rotor pair and the bearing seat and valve disc matched with both sides of the stator and rotor pair. The movement is normal without jamming, which will not cause performance degradation.

The radial piston hydraulic motor uses a cam ring with a special curve to make each plunger reciprocate several times within one cycle of cylinder block rotation, which is called multi action customized Low speed high torque cycloidal hydraulic motor Internal curve radial plunger hydraulic motor (referred to as internal curve motor) is used. The internal curve motor has the advantages of small size, light weight, radial force balance, small torque ripple, high starting efficiency, stable operation at very low speed, etc. It has been widely used Low speed high torque cycloidal hydraulic motor manufactor In marine machinery. Working principle of inner curve motor: the inner wall of the cam ring (housing) is composed of x evenly distributed curved surfaces with the same shape. Each curved surface with the same shape can be divided into two symmetrical sides. The side that allows the plunger set to extend outward is the working section (oil inlet section), and the opposite side is called the oil return section. The number of reciprocating times of each plunger per revolution of the hydraulic motor is equal to the number of curved surfaces of the cam ring x (x is called the number of times of action of the motor).

The hydraulic motor is usually put into operation Zhongshan customized 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 customized Low speed high torque cycloidal hydraulic motor 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.
