(Republic of Lithuania stainless steel cylinder,produced by Hengyu Group）
stainless steel cylinder are widely used in Republic of Lithuania，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed stainless steel cylinder for customers from Republic of Lithuania.
stainless steel cylinder is the most important part of construction machinery, the traditional processing method is: broaching stainless steel cylinder block - fine boring stainless steel cylinder block - grinding stainless steel cylinder block. The rolling method is: broaching stainless steel cylinder block - fine boring stainless steel cylinder block - rolling stainless steel cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the stainless steel cylinder block is about 1-2 days, rolling 1 meter of the stainless steel 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 stainless steel cylinder increases by 25%. If the stainless steel 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 stainless steel cylinders, you must take the rolling production process. After the stainless steel 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.
The wear of the hard chromium plating layer of the stainless steel cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
stainless steel cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.
stainless steel cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the stainless steel cylinder is placed for a period of time, the stainless steel cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.
What is a differential cylinder?
The differential cylinder is by connecting the return oil of the rod cavity through the pipeline, allowing them to flow into the rodless cavity, thereby speeding up the extension speed of the piston rod. In fact, the cylinder is still the cylinder, but the oil circuit is related to the connection. The oil connection mode in which both chambers of a single rod hydraulic cylinder are fed hydraulic oil is called differential connection.
How to calculate the hydraulic cylinder pressure? How much pressure can put up how much weight?
If you want to calculate the pressure of the cylinder, you must know the inner diameter of the cylinder, if the piston rod is needed to lift the weight, it should be: cylinder (no piston rod end) pressure = load (4000N) ÷{(PI /4)X the square of the cylinder diameter (mm) ", it has nothing to do with the piston rod diameter, the rod diameter of the piston rod is only related to the stability of the cylinder. The pressure inside the cylinder should be p=F/S=400×10/(3.14×(0.5×25)×(0.5×25))=8.15MPa which means that you need to provide at least that much pressure to complete the operation.
