This article mainly introduces:

Slovenia hydraulic cylinder,spring return cylinder manufacturer,spring return cylinder

(Slovenia spring return cylinder,produced by Hebei Hengyu company）

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

Introduction to spring return cylinder:

The pressure of the sliding surface of the spring return 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 spring return 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 spring return cylinder: When disassembly spring return cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the spring return cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the spring return cylinder.

How to determine the working pressure of the spring return 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, spring return 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.

When purchasing the spring return cylinder, try to clarify the following parameters of the spring return cylinder: A. spring return cylinder diameter, rod diameter, stroke; B. Working pressure or spring return cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right spring return cylinder type can be found accurately and quickly.

Answers to some questions about spring return cylinder:

How is the cylinder of hydraulic cylinder processed?
As the main parts of hydraulic cylinder, mining single pillar, hydraulic support, gun barrel and other products, its processing quality directly affects the life and reliability of the whole product. Cylinder 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 cylinder is deep hole processing, which has always troubled the processing personnel. Due to the residual compressive stress on the surface of the surface layer, the rolling machining is helpful to seal the small cracks on the surface and prevent 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 cylinder can be improved.

Need a hydraulic cylinder, vertical upward 10 seconds to lift 20 tons of weight up 2 meters, how large cylinder and rod, how much pressure to use the plunger pump and how big?
The first thing to determine the system pressure, let's say 25 mpa, can take into account cost and performance. 1 Cylinder area 20000/250=80 square cm cylinder diameter (80/3.14) squared x2=200 mm 2 cylinder volume 80x200=16000 ml =16 L 3 Required pump flow 16x60/10=96 L/min 4 Power 96x25/55=43 kW 45 kW motor is available.
