stern plate hydraulic cylinder are widely used in Malaysia，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed stern plate hydraulic cylinder for customers from Malaysia.

Introduction to stern plate hydraulic cylinder:

The scar on the sliding surface of the stern plate hydraulic cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the stern plate hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.

The internal leakage of the stern plate hydraulic cylinder should be prevented when the stern plate hydraulic cylinder is used. The internal leakage of stern plate hydraulic cylinder includes the leakage caused by excessive wear of stern plate hydraulic cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular stern plate hydraulic cylinder action. Troubleshooting method: Replace the rubber hose.

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.

Answers to some questions about stern plate hydraulic cylinder:

What's a minus 40 cylinder made of?
Construction with 1Cr18Ni9Ti, in low temperature conditions impact and tensile strength are very good, can withstand -100 degrees of low temperature, corrosion resistance, material price is not very high, more economic.

Design a hydraulic cylinder, the inner diameter of the cylinder is 100mm, what size of piston rod is best used?
This involves how much speed ratio you need, that is, the area ratio of the rod cavity and the rodless cavity, if the weight is relatively large, it is recommended that the speed ratio choose 2, that is, the piston rod diameter choose 70mm, under normal circumstances, the speed ratio choose 1.46, the piston rod diameter choose 55mm. Of course, there are many factors that affect the diameter of the piston rod, such as stroke, stroke is too long, in order to stabilize the work of the hydraulic cylinder, its diameter also needs to choose a relatively large, sometimes even non-standard products, need to choose according to the actual situation.
