Libya synchronous hydraulic cylinder

(Libya synchronous hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

synchronous hydraulic cylinder are widely used in Libya,because of high work efficiency,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed synchronous hydraulic cylinder for customers from Libya.

Introduction to synchronous hydraulic cylinder:

The coordination of the sliding parts of the synchronous hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

What kind of process is used in the synchronous hydraulic cylinder to make high-quality synchronous hydraulic cylinder products: the body is the main component of the synchronous hydraulic cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The synchronous hydraulic cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the synchronous hydraulic cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the 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 RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the synchronous hydraulic cylinder increases by 25%. If the service life of the synchronous hydraulic cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. synchronous hydraulic cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the synchronous hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and synchronous hydraulic cylinder are stuck or the synchronous hydraulic cylinder is blocked. At this time, no matter how to manipulate, the synchronous hydraulic cylinder does not move or moves very little. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the synchronous hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

In order to ensure the service life of the synchronous hydraulic cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the synchronous hydraulic cylinder, causing damage to the seal and causing leakage in the synchronous 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.

If the synchronous hydraulic cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

Answers to some questions about synchronous hydraulic cylinder:

Hydraulic cylinder application areas?
1, in the machine tool industry, 85% of the machine tool transmission system adopts hydraulic transmission and control. Such as grinding machine, milling machine, planer, broaching machine, press, shearing machine, and combined machine tools. 2, in the metallurgical industry, electric furnace control system, rolling mill control system, open furnace charging, converter control, blast furnace control, strip deviation and constant tension device are all using hydraulic cylinders. 3, in the construction machinery, the general use of hydraulic transmission, such as excavators, tire loaders, truck cranes, crawler bulldozers, tire cranes, self-propelled scrapers, graders and vibration rollers. 4, in agricultural machinery, the use of hydraulic cylinders is also widely used, such as combine harvesters, tractors and so on.

Is rubber or polyurethane better for V-ring of hydraulic cylinder?
The hydraulic cylinder V-type seal ring is better with polyurethane, and chlorine rubber is used for various chemicals and high temperatures, especially when there are wear-resistant requirements, polyurethane rubber is needed. But the price of polyurethane rubber is much more expensive than the price of rubber. However, the V-ring material is most commonly used in nitrile and neoprene rubber, and natural rubber is used for sealing water and air. Butyl rubber is used for non-combustible hydraulic fluids and phosphate ester hydraulic fluids. The advantage is that the price is cheaper than the polyurethane material, and the disadvantage is that it is not wear-resistant and the anti-aging property is relatively poor.
