Saudi Arabia retractable cylinder

(Saudi Arabia retractable cylinder,produced by Hebei Hengyu company)

retractable cylinder are widely used in Saudi Arabia,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed retractable cylinder for customers from Saudi Arabia.

Introduction to retractable cylinder:

We can not just consider the price and ignore the quality when we purchase the retractable cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the retractable cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the retractable cylinder is not required.

The oil retractable cylinder is a part of the hydraulic system, in the hydraulic system, to reasonably design the heat dissipation system, to prevent the oil temperature is too high is the key to keep the hydraulic oil temperature normal. The temperature of the system should be kept in a suitable range to reduce the energy released when the bubble bursts. While not affecting the normal circulation of the coolant, a certain amount of anti-corrosion additives can be appropriately added to inhibit rust. When operating the hydraulic system, we should strive to be stable, not too fast, too strong, and try to reduce the impact of hydraulic oil on hydraulic components.

In order to ensure the service life of the retractable cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

The retractable cylinder should be used correctly and maintained regularly. The retractable 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 retractable cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

Answers to some questions about retractable 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!

What is the meaning of dead volume in hydraulic cylinder?
Closed volume, also known as dead zone volume Positive displacement pump is dependent on the change of sealing working volume to achieve suction and pressure oil, in order not to make the suction and pressure oil cavity interworking, there is an oil sealing area between the suction and pressure oil cavity, when the sealing working volume passes through the oil sealing area, neither pressure oil cavity nor oil suction cavity communication, forming a closed sealing volume. The unloading groove is opened, and the grooving principle is that the sealing volume decreases and the oil pressure chamber is communicated, and the sealing volume increases and the oil suction chamber is communicated.
