With the rapid development of China's economy, since the reform and opening up, the machinery industry has improved the advanced productivity in China by constantly introducing foreign technology. Especially after China's accession to the WTO, the machinery industry has accelerated scientific and technological innovation, and the annual export of equipment has continued to grow. With the continuous technological innovation of the hydraulic press industry in China, a number of high-tech industrial companies have emerged, and there are thousands of domestic production enterprises with a certain scale. Hydraulic press products are commonly used in stamping processing and stamping forming processes, such as forging, stamping, cold extrusion, straightening, bending, flanging, plate stretching, powder metallurgy, press fitting, etc. They are metal, plastic, rubber, wood, powder and other products. It can not only meet the functional diversification of electromechanical products to the maximum extent, but also is the basic guarantee for completing major projects and major technological transformation. Now the hydraulic press products have been widely used in automobile, engineering machinery, agricultural machinery, machine tools, plastic machinery, metallurgy and mining, power generation equipment, railway, ship, light industry, electronics, and defense industry products.

Actuator: hydraulic cylinder, hydraulic motor and swing hydraulic motor. Function: convert the pressure energy of liquid into mechanical energy, which is used to drive the working mechanism to do work and realize reciprocating straight customized M+S cycloidal motor Linear motion, continuous rotation or swing; Governor: pressure, flow, direction control valve and other control elements. Function: control the oil pressure, flow and direction from the pump to the actuator in the hydraulic system, so as to control the force (torque) and speed output by the actuator Wuhu M+S cycloidal motor Degree (speed) and direction, to ensure that the main engine working mechanism driven by the actuator can complete the predetermined motion law; Hydraulic auxiliary device: oil tank, pipe fittings, filter, heat exchanger, accumulator, indicating instrument, etc.

Hydraulic transmission system, the hydraulic transmission system is generally an open loop system without feedback, which mainly transmits power, supplemented by information, and pursues the perfection of transmission characteristics. Hydraulic elements customized M+S cycloidal motor The characteristics of components and their interactions determine the working characteristics of the system, and its working quality is greatly affected by the changes of working conditions. Hydraulic drive system is widely used. The hydraulic system of most industrial equipment belongs to this category. In the hydraulic control system, servo valves and other electrohydraulic devices are mostly used in the hydraulic control system M+S cycloidal motor Price The control valve constitutes a closed-loop system with feedback, which mainly transmits information, supplemented by power, and pursues the perfection of control performance. The system adds detection feedback, which can combine common components into an accurate control system, and its control quality is less affected by the change of working conditions. Hydraulic control system is widely used in high-precision CNC machine tools, metallurgy, aerospace and other industries.

1. Air intrusion. When the air intrudes into the hydraulic system, it has a large volume in the low-pressure area. When it enters the high-pressure area, it is compressed, and the volume suddenly decreases. When it enters the low-pressure area, the volume suddenly increases, resulting in a sudden change in the bubble volume, that is, "explosion" phenomenon, resulting in noise. Solution: Generally, the hydraulic cylinder is equipped with an exhaust device customized M+S cycloidal motor Exhaust. In addition, a common method is to exhaust the actuator several times during the fast full stroke after startup. 2. The quality of the hydraulic pump or motor is poor. The quality of the hydraulic pump is poor, the accuracy does not fully meet the technical requirements, the pressure and flow fluctuations are large, the oil trapping phenomenon has not been eliminated well, and poor sealing and poor bearing quality are the main reasons for the noise. In use, due to wear of hydraulic pump parts, excessive clearance, insufficient flow Wuhu Price The force is easy to fluctuate and will also produce noise.

The ignition time of internal combustion engines can be compared with this. It can be seen from the working principle of the cycloidal hydraulic motor that the oil sleeve and the rotor rotate synchronously, and the accuracy refers to the accuracy of the oil distribution link matching with the rotor to rotate the oil inlet, seal and discharge. There are many factors customized M+S cycloidal motor It will affect the oil distribution accuracy, such as the asymmetry of the rotor spline and cycloid tooth shape, the relative position accuracy of the stator sleeve needle hole and bolt hole, and the relative position asymmetry of the pin hole and spline on the output shaft and its internal spline, M+S cycloidal motor Price The relative position accuracy of the longitudinal oil groove and the relative wedge groove of the coupling, and the asymmetry of splines at both ends of the coupling. As long as the above factors are controlled within the tolerance range, they will not have a great impact on the oil distribution accuracy, because all processing errors will not be offset.
