(Brazil self-locking hydraulic cylinder,produced by Hengyu Group）

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

Introduction to self-locking hydraulic cylinder:

The self-locking hydraulic cylinder should be used correctly and maintained regularly. The self-locking hydraulic cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the self-locking hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

In recent years, the processing process of the self-locking hydraulic cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

The definition of the minimum starting pressure of the self-locking hydraulic cylinder refers to the minimum working pressure of the self-locking hydraulic cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the self-locking hydraulic cylinder parts and the size of the sealing friction.

Regular maintenance of the self-locking hydraulic cylinder includes: regular tightening, self-locking hydraulic cylinder fastening screws and gland screws, self-locking hydraulic cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the self-locking hydraulic cylinder once a year. Clean regularly, the self-locking hydraulic cylinder is cleaned every other year, and the seals are replaced while cleaning.

Answers to some questions about self-locking hydraulic 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!

The diameter of the cylinder is 180mm and the pressure is 14mpa. How many tons can the cylinder hold?
Calculate the area of the cylinder, 3.14*9*9=254.34 square centimeters, take the approximate number of engineering, 1 mpa pressure is about 10 kg per square centimeter, 14 mpa pressure is 140 kg per square centimeter, that is 254.34*140=35607.6 kilograms, it can be known that the cylinder can be about 35 tons in theory.
