Slovenia hydraulic cylinder,yg series hydraulic cylinder manufacturer,yg series hydraulic cylinder(Slovenia yg series hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
yg series hydraulic cylinder are widely used in Slovenia,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed yg series hydraulic cylinder for customers from Slovenia.
yg series hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching yg series hydraulic cylinder block - fine boring yg series hydraulic cylinder block - grinding yg series hydraulic cylinder block. The rolling method is: broaching yg series hydraulic cylinder block - fine boring yg series hydraulic cylinder block - rolling yg series hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the yg series hydraulic cylinder block is about 1-2 days, rolling 1 meter of the yg series hydraulic cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the yg series hydraulic cylinder increases by 25%. If the yg series hydraulic cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality yg series hydraulic cylinders, you must take the rolling production process. After the yg series hydraulic cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.
Disassembly yg series hydraulic cylinder: When disassembly yg series hydraulic cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the yg series hydraulic cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the yg series hydraulic cylinder.
yg series hydraulic cylinder buffer valve inspection and maintenance: For the valve buffer yg series hydraulic cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.
If the piston rod and yg series hydraulic cylinder are stuck or the yg series hydraulic cylinder is blocked, at this time, no matter how to operate, the yg series hydraulic cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the yg series hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.
What is a mold core cylinder?
Simple plastic parts can be directly pushed out by the ejector rod after injection molding, complex plastic parts can not be directly pushed out by the ejector rod after injection molding, to make the interference part active, control its position through the cylinder (injection molding into the mold, so that the shape of the plastic parts meet the demand, exit after opening the mold, so that the plastic parts are smoothly pushed out), This kind of cylinder is the mold core cylinder.
How does the hydraulic solenoid valve realize that the cylinder stops at any position?
Use an O-type medium function solenoid directional valve, or use a Y-type solenoid directional valve and a hydraulically controlled check valve.
