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

synchronous hydraulic cylinder are widely used in Denmark，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed synchronous hydraulic cylinder for customers from Denmark.

Introduction to synchronous hydraulic cylinder:

synchronous hydraulic cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the synchronous hydraulic cylinder head itself is the guide sleeve of the piston rod, the synchronous hydraulic cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the synchronous hydraulic cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

In recent years, the processing process of the synchronous hydraulic cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

In the case of serious wear on the inner surface of the synchronous hydraulic cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the synchronous hydraulic cylinder manufacturing process for replacement. The synchronous hydraulic cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

synchronous hydraulic cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the synchronous hydraulic cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

Answers to some questions about synchronous hydraulic cylinder:

How to distinguish cylinder rod head and cylinder bottom?
One end of the piston rod can be telescopic is the rod head, and the one behind is the bottom of the cylinder, which is the single rod cylinder.

How to distinguish large cavity and small cavity of excavator rod cylinder ?
Single rod piston cylinder is a form of cylinder that is used relatively most, and the boom, bucket, dozer shovel cylinder are all in this form. Among them, the rodless cavity is also called the large cavity, and the rodless cavity is also called the small cavity. Therefore, the cylinder cavity on the side with the exposed piston rod is the small cavity, and the cylinder cavity on the side without the exposed rod is the large cavity.
