Libya spring return cylinder

(Libya spring return cylinder,produced by Hengyu Hydraulic Co., Ltd)

spring return cylinder are widely used in Libya,because of no need for deceleration device,smooth movement,long service life.So our company has designed spring return cylinder for customers from Libya.

Introduction to spring return cylinder:

Analysis of commonly used seals: The wear ring and slip ring commonly used on the spring return cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

When the hydraulic oil is not pumped into the spring return cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the spring return cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

The spring return cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the spring return cylinder should pay attention to: the operation should be as far away from the spring return cylinder as possible, to avoid falling objects, knocking, rubbing the spring return cylinder coating. When cleaning the spring return cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the spring return cylinder when the oil temperature exceeds 70 ° C.

When the spring return cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

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.

Can the hydraulic oil in the cylinder return to the tank?
Yes, there is a way, for example, first remove the cylinder from the machine, and then connect the two pipes on the cylinder, so that the cylinder piston rod is completely retracted into the cylinder, at this time, the piston is with the bottom, and the rear chamber is almost no oil, and then screw off the joint at the end of the front chamber by the hydraulic station, and put it in an empty bucket. Finally, insert the gas pipe into the oil port of the rear chamber. Open the air source, and then the rod will run out, and you'll drain the hydraulic oil from the end of the rod, which requires a source of air on site.
