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

Introduction to synchronous hydraulic cylinder:

synchronous hydraulic cylinders in series, parallel and series parallel. Series: In the synchronous hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the synchronous hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the synchronous hydraulic cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the synchronous hydraulic cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

If the synchronous hydraulic cylinder slips or crawls, please check whether there is astringency inside the synchronous hydraulic cylinder, because the internal parts of the synchronous hydraulic cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the synchronous hydraulic cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the synchronous hydraulic cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.

The pressure of the sliding surface of the synchronous hydraulic cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the synchronous hydraulic cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.

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

Answers to some questions about synchronous hydraulic cylinder:

Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.

What material should be selected to seal the cylinder?
The choice of material for sealing is related to the working environment, strength, and medium of your equipment.
