stern plate hydraulic cylinder are widely used in Vietnam，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed stern plate hydraulic cylinder for customers from Vietnam.

Introduction to stern plate hydraulic cylinder:

stern plate hydraulic cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the stern plate hydraulic cylinder head itself is the guide sleeve of the piston rod, the stern plate hydraulic cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the stern plate hydraulic cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

When using the stern plate hydraulic cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the stern plate hydraulic cylinder block. If the stern plate hydraulic cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the stern plate hydraulic cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the stern plate hydraulic cylinder, so that the working efficiency of the stern plate hydraulic cylinder is reduced.

How the cavitation of the stern plate hydraulic cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the stern plate hydraulic cylinder, resulting in corrosive damage to the parts.

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.

Answers to some questions about stern plate hydraulic cylinder:

How many kinds of cylinder seal repair kit are there?
Very much, a wide variety of imported and domestic, J type, UHS, DHS, O-ring, Sterseal, etc., as well as support bars, materials are different, according to the size of the pressure selection is different, the appearance of the structure is different, the size is a variety, maintenance is generally selected according to the needs of the cylinder.

What is the safety factor of 25MPa cylinder wall thickness?
Safety factor n can take 3 cylinder material allowable stress [s]=sb/n δ/D=0.08 ~ 0.3 cylinder wall thickness δ=PMAX*D/ (2.3[s]-3PMAX) δ/D≤0.08 cylinder wall thickness δ=PMAX*D/2[s] P < 16MPa, Pmax=1.5Pn; P > 16MPa, Pmax=1.25Pn cold-drawn tube or honing tube is better!
