Jordan hydraulic cylinder,series synchronous cylinder manufacturer,series synchronous cylinder

(Jordan series synchronous cylinder,produced by Hengyu Group）

series synchronous cylinder are widely used in Jordan，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed series synchronous cylinder for customers from Jordan.

Introduction to series synchronous cylinder:

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

In use, the series synchronous cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the series synchronous cylinder.

Because of the slightly complex structure of the buffer series synchronous cylinder, sometimes there will be problems, such as when the series synchronous cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

Analysis of commonly used seals: The wear ring and slip ring commonly used on the series synchronous cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

Answers to some questions about series synchronous cylinder:

How to deal with hydraulic cylinder inner wall rag, local wear serious or corrosion?
It can be reparied if the inner wall of the hydraulic cylinder is frayed, local wear or corrosion. We can use the inner wall cold melting copper technology, it has the following advantages: first, the temperature is low, the operating temperature is less than 180 degrees, and the heat affected zone is small. Second: high hardness is up to Brinell hardness 280, wear resistance and anti-corrosion. Third: the process is mature, some large coal mills have been repaired with this method and the effect is remarkable.

How many boom cylinders, bucket rod cylinders and bucket cylinders are there in a small single-bucket excavator?
one for bucket, one for forearm, only one piece for a small excavator under the big arm, two pieces for medium and large excavator.
