El Salvador hydraulic cylinder,stacker cylinder manufacturer,stacker cylinder(El Salvador stacker cylinder,produced by Hengyu Hydraulic Cylinder Factory)
stacker cylinder are widely used in El Salvador,because of high work efficiency,simple structure and reliable operation,clever hydraulic energy conversion.So our company has designed stacker cylinder for customers from El Salvador.
When the control pressure of the hydraulic system is too low, the stacker 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 quality of the stacker cylinder can not be ignored in the purchase of the stacker cylinder. The stacker cylinder is the main component of the stacker cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. stacker cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of stacker cylinder is deep hole processing, which has always troubled the processing personnel.
The stacker 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 stacker cylinder, bite. Elimination method: When installing the stacker cylinder, ensure that the axis position of the stacker cylinder is consistent with the direction of movement; Make the load borne by the stacker cylinder as far as possible through the stacker cylinder axis, to avoid the phenomenon of eccentricity.
The definition of the minimum stable speed refers to the minimum movement speed of the stacker cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the stacker cylinder that undertakes different work has different requirements for the minimum stable speed.
What is the clearance between the cylinder and the piston?
The gap between the cylinder and the piston in the radius is generally 40 wires, that is, about 0.4mm, and the gap of the cylinder with different diameters will be slightly different. Generally, the inner diameter of the cylinder is larger than the outer diameter of the piston, so as to prevent the friction between the outer surface and the inner surface of the cylinder during the operation of the piston. In order to ensure that the cylinder has a rod cavity and a rodless cavity seal, a sealing device, that is, a sealing ring, is installed on the outer surface of the piston. The sealing ring form is not exactly the same, the O-type sealing ring is generally used under low pressure, and the lip sealing ring is used under high pressure. At the same time, the outer circle of the piston is also equipped with a dust ring and a wear ring. As long as the cylinder seal fails, all the internal seals should be replaced.
What steel pipe does hydraulic cylinder use? This problem is very general. Carbon steel pipe or ordinary seamless steel pipe are all ok, but then there are rolling, quilting, heat treatment and other steps, and the requirements are different, the wall thickness is different, the material is different. It depends on the circumstances.
