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 Low speed high torque cycloidal hydraulic 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 Taizhou Low speed high torque cycloidal hydraulic 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.

After disassembling and inspecting the hydraulic motor installed on the drill, it was found that the friction surface of the valve disc and the port plate of the hydraulic motor was severely worn, and the deepest worn part was 0. 15mm; The output shaft oil seal is leaking. Cause analysis of oil leakage of output shaft oil seal. After disassembly inspection and test, the axial and radial clearances of the output shaft meet the standard requirements customized Low speed high torque cycloidal hydraulic motor There is no obvious wear on the oil seal mating surface. However, it is found that the oil seal rubber has hardened and its elasticity has deteriorated. With the increase of sealing lip wear, the pre tightening capacity and sealing performance decrease, and the excessive oil temperature accelerates the wear of sealing lip; In addition, due to the liquid Taizhou Low speed high torque cycloidal hydraulic motor The leakage of the pressure motor causes the back pressure in the housing to be too high, which further aggravates the wear and leakage of the sealing lip. The smaller the friction of the rotor in the stator sleeve, the higher the mechanical efficiency of the motor.

Generally, rolling bearing or hydrostatic sliding bearing, hydraulic customized Low speed high torque cycloidal hydraulic motor 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 Taizhou Low speed high torque cycloidal hydraulic motor High speed hydraulic motor, while the rated speed is lower than 500r/min, it belongs to low speed hydraulic motor.

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 customized Low speed high torque cycloidal hydraulic motor 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 Low speed high torque cycloidal hydraulic motor Manufacturer 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.

1) Select the hydraulic pump or motor with good quality and conduct regular maintenance. For example, if the tooth profile accuracy of the gear is low, grind the gear to meet the requirements of the contact surface; 2) If the vane pump has trapped oil, the triangular groove of the oil distributor should be corrected to remove the trapped oil; 3) If the axial clearance of the hydraulic pump is too large and the oil delivery is insufficient Low speed high torque cycloidal hydraulic motor Manufacturer Repair to keep the axial clearance within the allowable range; 4) If the hydraulic pump is not selected correctly, it should be replaced immediately. 3. The reversing valve is improperly adjusted. Improper adjustment of the reversing valve causes the valve core of the reversing valve to move too fast, resulting in reversing shock, noise and vibration. During operation, the valve core branch of hydraulic valve Taizhou Low speed high torque cycloidal hydraulic motor Support on the spring. When its frequency is close to the pulsating frequency of oil delivery rate of hydraulic pump or other vibration sources, vibration and noise will be generated.

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.
