This article mainly introduces:

Tunisia hydraulic cylinder,tension cylinder manufacturer,tension cylinder

(Tunisia tension cylinder,produced by Hebei Hengyu company）

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

Introduction to tension cylinder:

tension cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the tension cylinder is placed for a period of time, the tension cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

tension cylinder body inspection: The inner surface of the tension cylinder and the piston seal are the main factors causing the leakage in the tension cylinder, if the tension cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the tension cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

Regular maintenance of the tension cylinder includes: regular tightening, tension cylinder fastening screws and gland screws, tension cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the tension cylinder once a year. Clean regularly, the tension cylinder is cleaned every other year, and the seals are replaced while cleaning.

If the tension cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

Answers to some questions about tension cylinder:

How does the self-locking cylinder work?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil circuit itself is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.

What is st represented in the cylinder formula?
St is the original unit of kinematic viscosity, the abbreviation of Stokes, that is, Stokes, short for S. cm2/s has now been used. 1 s (St) = 10^-4m2/s.
