Finland hydraulic cylinder,stacker cylinder manufacturer,stacker cylinder(Finland stacker cylinder,produced by Hengyu Group)
stacker cylinder are widely used in Finland,because of excellent fatigue and impact resistance,smooth movement,high work efficiency.So our company has designed stacker cylinder for customers from Finland.
stacker cylinder piston rod material introduction: In general, we use 45 steel to produce stacker cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.
If the seal of the stacker cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.
When installing the stacker cylinder, the axial ends of the stacker cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the stacker cylinder, there is axial expansion. If the two ends of the stacker cylinder are fixed, all parts of the stacker cylinder will be deformed. When disassembling the stacker cylinder, it is strictly forbidden to hammer the stacker cylinder and the piston surface, such as the stacker cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.
Before the stacker cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.
How does the one-way solenoid valve control the hydraulic cylinder circuit?
If your cylinder is single-acting, you can use a one-way solenoid valve, such as some lifting platform hydraulic cylinder, the support valve used is one-way (two-position tee), that is, the cylinder extends out by the oil pressure top, the cylinder retracted by its own weight.
What do cylinder internal leakage and external leakage mean?
Internal leakage means that the piston seal in the cylinder is not strict, there is a leak between the two chambers of the cylinder, the oil is still in the cylinder, and the external leakage is that the oil leaks to the outside of the cylinder.
