Bulgaria unidirectional cylinder

(Bulgaria unidirectional cylinder,produced by Hengyu Hydraulic Cylinder Factory)

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

Introduction to unidirectional cylinder:

Causes and countermeasures of oil unidirectional cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the unidirectional cylinder will lead to premature wear of the piston seal, replace the piston seal; If the unidirectional cylinder is visibly scarred, the unidirectional cylinder must be replaced. It can be pressurized at one end of the unidirectional cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most unidirectional cylinder piston drift may not come from the unidirectional cylinder, the above method to determine the unidirectional cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

Improve the service life of the unidirectional cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the unidirectional cylinder (such as the unidirectional cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the unidirectional cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the unidirectional cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single unidirectional cylinder exhaust.

The unidirectional cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the unidirectional cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The unidirectional cylinder is basically composed of unidirectional cylinder and unidirectional cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

Protection of the unidirectional cylinder surface: During the dismantling process, safety protection should be carried out on the unidirectional cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the unidirectional cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the unidirectional cylinder should be cleaned up in time.

Answers to some questions about unidirectional cylinder:

What is the thin cylinder used for?
The principle is no different from ordinary cylinders, that is, the installation space is small, the formation is small, and it is suitable for some special occasions. For example, the space is compact and the place of small travel is used.

Why do two hydraulic cylinders lift out of sync?
There may be several situations (do not know the result of the equipment, may not be accurate) 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).
