Japan series synchronous cylinder

(Japan series synchronous cylinder,produced by Hengyu Hydraulic Co., Ltd)

series synchronous cylinder are widely used in Japan,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed series synchronous cylinder for customers from Japan.

Introduction to series synchronous cylinder:

The piston rod and guide sleeve function of the series synchronous cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

When the long-stroke series synchronous cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in series synchronous cylinder head seal damage, oil leakage, and piston sleep in the series synchronous cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the series synchronous cylinder; The piston and the piston rod are connected with a spherical joint.

The machining accuracy of the series synchronous cylinder depends on the level of equipment, production technology and testing means. series synchronous cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

How to determine the working pressure of the series synchronous cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, series synchronous cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.

Answers to some questions about series synchronous cylinder:

How big is the motor and oil pump for the 80 cylinder?
Pump motor selection is not only related to cylinder diameter but also speed system, it is recommended to provide system diagram and speed requirements, generally speaking, most of the 80 cylinder on the market is equipped with 3-4KW motor, 10-20 oil pump.

What is hydraulic cylinder internal leakage and external leakage?
The internal leakage of the hydraulic cylinder refers to the leakage of the piston head seal of the double-acting cylinder, and the leakage occurs inside the cylinder; The external leakage refers to the leakage phenomenon between the cylinder head (or cylinder guide sleeve) and the plunger rod (or piston rod) and the seal between the guide sleeve and the cylinder block, and the oil in the hydraulic cylinder leaks to the outside.
