Algeria hydraulic cylinder,trailer hydraulic cylinder manufacturer,trailer hydraulic cylinder(Algeria trailer hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
trailer hydraulic cylinder are widely used in Algeria,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed trailer hydraulic cylinder for customers from Algeria.
The trailer hydraulic cylinder is mainly composed of body, piston, piston rod, trailer hydraulic cylinder head, trailer hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the trailer hydraulic cylinder into two chambers, and moves reciprocally in the trailer hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the trailer hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the trailer hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the trailer hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the trailer hydraulic cylinder bottom and the trailer hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the trailer hydraulic cylinder The working medium of the trailer hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; trailer hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the trailer hydraulic cylinder: The buffer structure of the trailer hydraulic cylinder is to prevent the piston from colliding with the trailer hydraulic cylinder head at the end of the stroke.
The definition of the minimum stable speed refers to the minimum movement speed of the trailer hydraulic cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the trailer hydraulic cylinder that undertakes different work has different requirements for the minimum stable speed.
The trailer hydraulic 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 trailer hydraulic cylinder should pay attention to: the operation should be as far away from the trailer hydraulic cylinder as possible, to avoid falling objects, knocking, rubbing the trailer hydraulic cylinder coating. When cleaning the trailer hydraulic cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the trailer hydraulic cylinder when the oil temperature exceeds 70 ° C.
If the trailer hydraulic 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.
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.
