Congo servo hydraulic cylinder

(Congo servo hydraulic cylinder,produced by Hebei Hengyu company)

servo hydraulic cylinder are widely used in Congo,because of clever hydraulic energy conversion,excellent temperature resistance,smooth movement.So our company has designed servo hydraulic cylinder for customers from Congo.

Introduction to servo hydraulic cylinder:

In order to ensure the service life of the servo hydraulic cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the servo hydraulic cylinder, causing damage to the seal and causing leakage in the servo hydraulic cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

servo hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching servo hydraulic cylinder block - fine boring servo hydraulic cylinder block - grinding servo hydraulic cylinder block. The rolling method is: broaching servo hydraulic cylinder block - fine boring servo hydraulic cylinder block - rolling servo hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the servo hydraulic cylinder block is about 1-2 days, rolling 1 meter of the servo hydraulic cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the servo hydraulic cylinder increases by 25%. If the servo hydraulic cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality servo hydraulic cylinders, you must take the rolling production process. After the servo hydraulic cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

When the servo hydraulic cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the servo hydraulic cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil servo hydraulic cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical servo hydraulic cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the servo hydraulic cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

The servo hydraulic cylinder should be vented: when the servo hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the servo hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the servo hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the servo hydraulic cylinder, the oil is best entered and discharged from the highest point of the servo hydraulic cylinder. servo hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Answers to some questions about servo hydraulic cylinder:

What does the maximum output force of the cylinder piston mean?
The maximum output of the cylinder is related to the pressure of the hydraulic system that you link to the cylinder. For example, the rated maximum output thrust of the MOB 50 cylinder is 1.3 tons and the rated pressure is 7Mpa. That is, when the input hydraulic oil pressure of the cylinder reaches 7Mpa, the maximum output thrust of the cylinder is only 0.98 tons. When the input hydraulic pressure is only 5Mpa, the maximum output thrust of the cylinder is 1.3 tons. Because the pressure of the cylinder limit is only 7Mpa, if the oil pressure of the input system exceeds 7Mpa, the cylinder can not withstand the pressure burst, and it is damaged.

What is the material of the lift cylinder?
The cylinder is composed of many parts. The cylinder also contains the seal and the installation port at both ends, the material of these two parts is not easy to determine if there is no physical object. The cylinder body is generally 20 steel, 45 steel, 27SiMn and other materials, and the piston rod is generally 40Cr, 45 steel and other materials.
