Spain synchronous hydraulic cylinder

(Spain synchronous hydraulic cylinder,produced by Hebei Hengyu company)

synchronous hydraulic cylinder are widely used in Spain,because of simple structure and reliable operation,no transmission clearance,excellent temperature resistance.So our company has designed synchronous hydraulic cylinder for customers from Spain.

Introduction to synchronous hydraulic cylinder:

synchronous hydraulic cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

What kind of process is used in the synchronous hydraulic cylinder to make high-quality synchronous hydraulic cylinder products: the body is the main component of the synchronous hydraulic cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The synchronous hydraulic cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the synchronous hydraulic cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the 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 RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the synchronous hydraulic cylinder increases by 25%. If the service life of the synchronous hydraulic cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. synchronous hydraulic cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the synchronous hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and synchronous hydraulic cylinder are stuck or the synchronous hydraulic cylinder is blocked. At this time, no matter how to manipulate, the synchronous hydraulic cylinder does not move or moves very little. 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 synchronous hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

When the synchronous hydraulic cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the synchronous hydraulic cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

synchronous hydraulic cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards synchronous hydraulic cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the synchronous hydraulic cylinder guide is determined by the length of the stroke. Check the strength of synchronous hydraulic cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

Answers to some questions about synchronous hydraulic cylinder:

How to design the guide sleeve of cylinder diameter 400?
The purpose of the guide sleeve is to guide and seal. Therefore, it is necessary to look at the speed of the piston rod, working pressure and radial force. High speed, medium pressure, no (or very little) radial force, with a Steseal. Low speed and heavy load, medium radial force, combined seal. High speed and heavy load, large radial force, sealed with DU sleeve + copper ring + combination. The combination seal must have a lubricating oil passage, and a seal must be added to the outside of the oil passage.

Why does the hydraulic cylinder go up to the top and then slowly go down?
Leakage in the cylinder or the hydraulic valve that controls the cylinder, can be replaced and removed. Or add a pressure retaining valve to the hydraulic system to ensure pressure.
