500 ton hydraulic cylinder are widely used in The Philippines,because of no need for deceleration device,long service life,smooth movement.So our company has designed 500 ton hydraulic cylinder for customers from The Philippines.
The 500 ton hydraulic cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the 500 ton hydraulic cylinder, bite. Elimination method: When installing the 500 ton hydraulic cylinder, ensure that the axis position of the 500 ton hydraulic cylinder is consistent with the direction of movement; Make the load borne by the 500 ton hydraulic cylinder as far as possible through the 500 ton hydraulic cylinder axis, to avoid the phenomenon of eccentricity.
500 ton 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 500 ton hydraulic cylinder head itself is the guide sleeve of the piston rod, the 500 ton 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 500 ton hydraulic cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.
If the 500 ton hydraulic cylinder slips or crawls, please check whether there is astringency inside the 500 ton hydraulic cylinder, because the internal parts of the 500 ton hydraulic cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the 500 ton hydraulic cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the 500 ton hydraulic cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.
The definition of the minimum stable speed refers to the minimum movement speed of the 500 ton hydraulic cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the 500 ton hydraulic cylinder that undertakes different work has different requirements for the minimum stable speed.
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!
Why the injection cylinder retreating after the injection molding machine is started?
It is likely that the projected area of the molded plastic parts is large or the injection pressure set is relatively large, resulting in the expansion force exceeding the clamping force of the injection molding machine, so the mold is backward. You can do the following attempts: 1, reduce the injection force of the injection molding machine; 2, if the injection molding part can not be well formed by reducing the injection force, it is recommended to install the mold to a larger injection molding machine.
