Nigeria tailplate hydraulic cylinder,tailplate hydraulic cylinder manufacturer(Nigeria tailplate hydraulic cylinder,produced by Hengyu Group)
tailplate hydraulic cylinder are widely used in Nigeria,because of powerful torque,clever hydraulic energy conversion,no transmission clearance.So our company has designed tailplate hydraulic cylinder for customers from Nigeria.
The internal leakage of the tailplate hydraulic cylinder is an important indicator to measure the quality of the tailplate hydraulic cylinder: the internal leakage of the tailplate hydraulic cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the tailplate hydraulic cylinder, so that the tailplate hydraulic cylinder can not accurately and stably stop in a certain position of the tailplate hydraulic cylinder, so it is one of the main indicators of the tailplate hydraulic cylinder.
The difference between the plunger tailplate hydraulic cylinder and the piston tailplate hydraulic cylinder is that the piston in the tailplate hydraulic cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type tailplate hydraulic cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.
When installing the tailplate hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the tailplate hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the tailplate hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the tailplate hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the tailplate hydraulic cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.
The tailplate hydraulic cylinder is mainly composed of body, piston, piston rod, tailplate hydraulic cylinder head, tailplate hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the tailplate hydraulic cylinder into two chambers, and moves reciprocally in the tailplate 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 tailplate hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the tailplate 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 tailplate 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 tailplate hydraulic cylinder bottom and the tailplate hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the tailplate hydraulic cylinder The working medium of the tailplate hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; tailplate 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 tailplate hydraulic cylinder: The buffer structure of the tailplate hydraulic cylinder is to prevent the piston from colliding with the tailplate hydraulic cylinder head at the end of the stroke.
What are the problems that cause hydraulic cylinder shaking?
1, the oil supply is not smooth, the hydraulic oil filter is half blocked. 2. The oil level in the oil storage tank is lower than the minimum oil level. 3, there is air in the hydraulic system. 4, the supply oil pump is damaged or not working properly. 5, the hydraulic oil is not replaced for a long time.
What factors does the movement speed of the cylinder in the hydraulic system depend on?
The hydraulic system should be the piston movement in the cylinder, and the speed should also be the speed of the piston, according to the piston speed formula: v=4qm/pai*(D^2-d^2) where q is the flow rate of the input hydraulic cylinder, m is the volumetric efficiency of the hydraulic cylinder, D, d is the diameter of the piston and piston rod, because other factors are determined, the movement speed of the cylinder depends on the flow rate.
