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

spring return cylinder are widely used in Kenya，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed spring return cylinder for customers from Kenya.

Introduction to spring return cylinder:

The assembly work of the spring return cylinder has a great impact on the quality of the spring return cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

Factors that should be considered when selecting the oil seal in the spring return cylinder: some specific factors should be taken into account when selecting the oil seal in the spring return cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: spring return cylinder diameter, piston rod diameter, piston rod and piston groove size, spring return cylinder working pressure, spring return cylinder movement speed, hydraulic system oil temperature and spring return cylinder working environment.

The meaning of the spring return cylinder model marked by the spring return cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the spring return cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the spring return cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

spring return cylinder buffer valve inspection and maintenance: For the valve buffer spring return cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

Answers to some questions about spring return cylinder:

How to calculate the tonnage of the hydraulic press? Example: The input cylinder pressure is 5Mpa, the end area of the cylinder piston is 100mm, and how much is the thrust tonnage?
F=P*S=5*10^6*3.14*(1/20)^2=39250N.

What is the clearance between the cylinder and the piston?
The gap between the cylinder and the piston in the radius is generally 40 wires, that is, about 0.4mm, and the gap of the cylinder with different diameters will be slightly different. Generally, the inner diameter of the cylinder is larger than the outer diameter of the piston, so as to prevent the friction between the outer surface and the inner surface of the cylinder during the operation of the piston. In order to ensure that the cylinder has a rod cavity and a rodless cavity seal, a sealing device, that is, a sealing ring, is installed on the outer surface of the piston. The sealing ring form is not exactly the same, the O-type sealing ring is generally used under low pressure, and the lip sealing ring is used under high pressure. At the same time, the outer circle of the piston is also equipped with a dust ring and a wear ring. As long as the cylinder seal fails, all the internal seals should be replaced.
