Belgium hydraulic cylinder,trunnion cylinder manufacturer,trunnion cylinder(Belgium trunnion cylinder,produced by Hebei Hengyu company)
trunnion cylinder are widely used in Belgium,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed trunnion cylinder for customers from Belgium.
The trunnion 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 trunnion cylinder, bite. Elimination method: When installing the trunnion cylinder, ensure that the axis position of the trunnion cylinder is consistent with the direction of movement; Make the load borne by the trunnion cylinder as far as possible through the trunnion cylinder axis, to avoid the phenomenon of eccentricity.
If the trunnion cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.
The scar on the sliding surface of the trunnion cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the trunnion cylinder wall. Therefore, before installation, these scars must be fully repaired.
The trunnion cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the trunnion cylinder should pay attention to: the operation should be as far away from the trunnion cylinder as possible, to avoid falling objects, knocking, rubbing the trunnion cylinder coating. When cleaning the trunnion cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the trunnion cylinder when the oil temperature exceeds 70 ° C.
What are the differences between hydraulic cylinder and pneumatic cylinder, what are their advantages and disadvantages?
Hydraulic Cylinder: small body and large force, constant speed and variable speed (easy to change), the adjustment of output is also convenient, and the degree of freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Pneumatic Cylinder: easy to control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, so it is more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion. Because the pressure used in the pneumatic system is generally in the range of 0.2-1.0Mpa, the cylinder is not suitable for high power component.
100 tons press, the cylinder diameter is 250, how much pressure?
100 tons hydraulic press, if it is a single acting hydraulic cylinder, the required oil pressure is the nominal force divided by the cross-sectional area of the cylinder piston. One hundred tons of its pressure is 1000 kN (1000000N), the diameter of the cylinder is 250 mm, its area is the circular rate multiplied by the square of the radius, is 49062.5 square mm, and then the pressure divided by the area of the oil pressure is 20.38MPa. Therefore, a hydraulic pressure of 20.38 mpa is required for a 250 diameter cylinder to obtain 100 tons of pressure.
