The weight per unit of electricity is very light. Statistics show that the weight of hydraulic pump and hydraulic motor per unit power is only the generator. 1/10 of the motor, hydraulic pump and hydraulic motor can be as small as 0.0025N/W, and the generator and motor with the same power can be about 0.03N/W. As for size, the former is about 12%~13% of the latter. In terms of output force, it is easy to get extremely high pressure hydraulic fluid with a pump, which will produce great force after being delivered to the hydraulic cylinder. Therefore, hydraulic technology has the advantages of light weight Zaozhuang Manufacturer The outstanding characteristics of small size and large output are conducive to the miniaturization and miniaturization of mechanical equipment and its control system for high-power operation. Flexible and convenient layout. The configuration of hydraulic components is not restricted by the strict space position, and it is easy to pass according to the needs of the machine. The connection of all parts of the system is realized through pipes, and the layout setting has great flexibility want to buy Large torque cycloidal motor Soft, which can form a complex system that is difficult to form by other methods.

As a hydraulic equipment, hydraulic motor has been widely used in many factories. Generally, we should master the assembly skills of the hydraulic motor: the hydraulic system should want to buy Large torque cycloidal motor Correct machining and assembly. The mounting surface of the hydraulic valve on the oil block should be straight, and the sealing surface of the sealing groove should be finished to avoid radial scratches. The preload of the connection between the hydraulic valve and the oil circuit block and the connection between the oil circuit blocks shall be sufficient to prevent surface separation. The hydraulic equipment shall be inspected according to relevant standards before assembly Large torque cycloidal motor Manufacturer Check the pressure leakage of system components. If problems are found, corresponding measures shall be taken. If the problem is serious, it should be replaced. Accurately formulate the assembly process documents of hydraulic equipment, configure necessary assembly tools, and strictly follow the assembly process. Keep the hydraulic components, accessories, sealing parts and pipe fittings clean to prevent contamination, and check the integrity of the sealing surface and connecting threads. The hydraulic connector should not be tightened too tightly, otherwise some parts will be severely deformed or even broken, causing leakage. Avoid damaging sealing parts during assembly.

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.

In the late 1850s, the original low-speed high torque hydraulic motor was developed from the fixed rotor part of the oil pump, which consists of an internal gear ring and matching teeth Zaozhuang Manufacturer Wheel or rotor. The inner gear ring is fixedly connected with the housing, and the oil entering from the oil port pushes the rotor to rotate around the center point. This slowly rotating rotor is driven and output by a spline shaft to become a cycloidal hydraulic motor. After the first cycloid motor came out, after decades of evolution, Jinjia hydraulic hydraulic motor delivers high efficiency energy for you. Another concept of motor also began to form. The motor installs the drum in the built-in ring gear. Motors with rollers can provide high starting Large torque cycloidal motor Manufacturer With the running torque, the drum reduces friction and improves efficiency. The low speed output shaft can also produce stable output.

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 want to buy Large torque cycloidal 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 Zaozhuang Large torque cycloidal 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.

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 want to buy Large torque 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 Zaozhuang Manufacturer The force is easy to fluctuate and will also produce noise.
