Paraguay hydraulic cylinder,push and pull the cylinder manufacturer,push and pull the cylinder

(Paraguay push and pull the cylinder,produced by Hengyu Group）

push and pull the cylinder are widely used in Paraguay，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed push and pull the cylinder for customers from Paraguay.

Introduction to push and pull the cylinder:

The oil push and pull the 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 the process of using the push and pull the cylinder, sometimes such a problem will occur, the push and pull the cylinder can not act immediately after the instruction of the push and pull the cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil push and pull the cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

The viscosity of the working oil used in the push and pull the cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

The push and pull the cylinder is not the same as the push and pull the cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the push and pull the cylinder can not be used as a high-power power component, but the push and pull the cylinder can be used as a relatively large power component, or the push and pull the cylinder system can be used.

Answers to some questions about push and pull 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!

Can pneumatic cylinder be used as hydraulic cylinder?
The pneumatic cylinder can only be used for pressure below 1MPA, and if it is used for hydraulic, the pressure should be under 1MPA, which may not meet the strength requirements. And the seals should use fluorine rubber to avoid corrosion. But pneumatic cylinder used as hydraulic cylinder is not whimsical, in fact, there is such a use. The pneumatic system has a natural defect, that is, the speed is unstable, especially in the case of low speed. The hydraulic pressure is very stable, if you do not want to buy a set of hydraulic system, while the strength of the cylinder is not large, you can use compressed air to push the hydraulic oil, with hydraulic oil to drive the cylinder, The force is the same as compressed air, but very smooth.
