Switzerland tailplate hydraulic cylinder

(Switzerland tailplate hydraulic cylinder,produced by Hebei Hengyu company)

tailplate hydraulic cylinder are widely used in Switzerland,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed tailplate hydraulic cylinder for customers from Switzerland.

Introduction to tailplate hydraulic cylinder:

The coordination of the sliding parts of the tailplate hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

The scar on the sliding surface of the tailplate hydraulic 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 tailplate hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.

Disassembly tailplate hydraulic cylinder: When disassembly tailplate hydraulic cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the tailplate hydraulic cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the tailplate hydraulic cylinder.

tailplate hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching tailplate hydraulic cylinder block - fine boring tailplate hydraulic cylinder block - grinding tailplate hydraulic cylinder block. The rolling method is: broaching tailplate hydraulic cylinder block - fine boring tailplate hydraulic cylinder block - rolling tailplate hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the tailplate hydraulic cylinder block is about 1-2 days, rolling 1 meter of the tailplate 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 tailplate hydraulic cylinder increases by 25%. If the tailplate 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 tailplate hydraulic cylinders, you must take the rolling production process. After the tailplate 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.

Answers to some questions about tailplate hydraulic cylinder:

How big gear pump need to use for 60*100 cylinder?
One cylinder size alone does not determine the size of the pump used. Choose the size of the pump, at least to know 1, the size of the load is how much, by the size of the load and the size of the cylinder and other conditions can be calculated the pressure required by the hydraulic system. 2. Speed of operation. From this speed and cylinder size, the required flow rate of the system is calculated. The relevant parameters of the pump can be selected by the pressure and flow rate to determine what kind of pump is required.

Why do two hydraulic cylinders lift out of sync?
There may be several situations (do not know the result of the equipment, may not be accurate) 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).
