(India stern plate hydraulic cylinder,produced by Hengyu Group）

stern plate hydraulic cylinder are widely used in India，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed stern plate hydraulic cylinder for customers from India.

Introduction to stern plate hydraulic cylinder:

Analysis of commonly used seals: The wear ring and slip ring commonly used on the stern plate hydraulic cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

The cavitation of the stern plate hydraulic cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the stern plate hydraulic cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

stern plate hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching stern plate hydraulic cylinder block - fine boring stern plate hydraulic cylinder block - grinding stern plate hydraulic cylinder block. The rolling method is: broaching stern plate hydraulic cylinder block - fine boring stern plate hydraulic cylinder block - rolling stern plate hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the stern plate hydraulic cylinder block is about 1-2 days, rolling 1 meter of the stern plate 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 stern plate hydraulic cylinder increases by 25%. If the stern plate 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 stern plate hydraulic cylinders, you must take the rolling production process. After the stern plate 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.

The daily inspection of the stern plate hydraulic cylinder includes: checking the connection of the stern plate hydraulic cylinder and the pipe joint for leaks. Check the stern plate hydraulic cylinder rod for leaks. Check the stern plate hydraulic cylinder connection for leaks. When the stern plate hydraulic cylinder moves, the work is normal and smooth. Whether the stern plate hydraulic cylinder has internal leakage.

Answers to some questions about stern plate hydraulic cylinder:

What material is the piston rod of the cylinder made of?
About the piston rod: ① Piston rods are usually made of 45# steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. ② The piston rod is generally designed as a cylinder, if the diameter is larger, the hollow piston rod can be used with 45# seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the rod surface needs to be chrome plated.

How many kilograms can the 63 cylinder hold?
The force of the cylinder is related to the cylinder diameter and pressure. 63 cylinder diameter (cylinder inner circle diameter), 21MPA pressure, thrust 6 tons.
