Ecuador hydraulic cylinder,hydraulic lifting cylinder manufacturer,hydraulic lifting cylinder
(Ecuador hydraulic lifting cylinder,produced by Hengyu Group）
hydraulic lifting cylinder are widely used in Ecuador，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed hydraulic lifting cylinder for customers from Ecuador.
When the control pressure of the hydraulic system is too low, the hydraulic lifting cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.
The viscosity of the working oil used in the hydraulic lifting 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.
After chrome plating of the piston rod of the hydraulic lifting cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.
At the rated pressure, the thrust of the hydraulic lifting cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the hydraulic lifting cylinder is related to the diameter of the hydraulic lifting cylinder, but not to the stroke of the hydraulic lifting cylinder. Moreover, the larger the hydraulic lifting cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the hydraulic lifting cylinder.
How to calculate the hydraulic cylinder pressure, how much pressure can put up how much weight?
There is a formula for air pressure, hydraulic pressure, water pressure: F=P×S type: f-cylinder or hydraulic cylinder output, unit is Newton (N) P- pressure, unit is Mpa S- effective area, unit is square millimeter (mm2), note: is the effective area, in the hydraulic cylinder to subtract the cross-sectional area of the piston rod.
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.
