Romania unidirectional cylinder

(Romania unidirectional cylinder,produced by Hebei Hengyu company)

unidirectional cylinder are widely used in Romania,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed unidirectional cylinder for customers from Romania.

Introduction to unidirectional cylinder:

1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.

The piston rod and guide sleeve function of the unidirectional cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

What kind of process is used in the unidirectional cylinder to make high-quality unidirectional cylinder products: the body is the main component of the unidirectional cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body 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 body is deep hole processing, which has always troubled the processing personnel. The unidirectional cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder 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 body can be improved. The correct rolling process of the unidirectional cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the unidirectional cylinder increases by 25%. If the service life of the unidirectional cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. unidirectional cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the unidirectional cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and unidirectional cylinder are stuck or the unidirectional cylinder is blocked. At this time, no matter how to manipulate, the unidirectional cylinder does not move or moves very little. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the unidirectional cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

unidirectional cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

Answers to some questions about unidirectional cylinder:

How to achieve hydraulic cylinder self-locking?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil self-locking 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.

How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.
