synchronous hydraulic cylinder are widely used in Ethiopia，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed synchronous hydraulic cylinder for customers from Ethiopia.

Introduction to synchronous hydraulic cylinder:

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.

At the rated pressure, the thrust of the synchronous hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the synchronous hydraulic cylinder is related to the diameter of the synchronous hydraulic cylinder, but not to the stroke of the synchronous hydraulic cylinder. Moreover, the larger the synchronous hydraulic cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the synchronous hydraulic cylinder.

synchronous hydraulic cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

The synchronous hydraulic cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the synchronous hydraulic cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the synchronous hydraulic cylinder wall due to the stiffness and the weight of the parts, causing scars.

Answers to some questions about synchronous hydraulic cylinder:

What does cylinder speed ratio mean?
The speed ratio of the cylinder is the ratio of the reciprocating speed of the piston, equal to the ratio of the rodless cavity area to the roded cavity area.

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.
