Uganda hydraulic cylinder,single rack cylinder manufacturer,single rack cylinder
(Uganda single rack cylinder,produced by Hebei Hengyu company）
single rack cylinder are widely used in Uganda，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed single rack cylinder for customers from Uganda.
How to repair the single rack cylinder body when it is damaged: When the single rack cylinder has trace deformation and shallow tensile marks, the single rack cylinder is repaired by strong honing process. The heavy honing process can repair single rack cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the single rack cylinder can meet the technical requirements.
Analysis of commonly used seals: The wear ring and slip ring commonly used on the single rack cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.
Do not enter foreign bodies when installing the single rack cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.
The repair method of single rack cylinder wear: 1. Metal repair material is applied to the scratched surface; The first layer should be thin, uniform and fully covered with the scratched surface to ensure the best adhesion between the material and the metal surface, and then apply the material to the entire repair site and press repeatedly to ensure that the material is filled and reaches the required thickness, so that it is slightly higher than the surface of the guide rail; 2, the material at 24℃ to fully achieve the performance of 24 hours, in order to save time, can be through the tungsten halogen lamp to increase the temperature, the temperature rises 11℃, the curing time will be reduced by half, the best curing temperature 70℃; 3. After the material is cured, use a fine grinding stone or a scraper to repair and smooth the material higher than the surface of the guide rail, and the construction is completed.
Why should the piston rod of the hydraulic cylinder be so precise? If you hope the cylinder has a long service cycle, then all parts need to be high-precision, not only the piston rod, but also the cylinder, the sealing groove, the surface roughness, the cylinder looks very simple. Any hydraulic factory can produce the cylinder, but the good cylinder is difficult to produce.
Why does the hydraulic cylinder ring?
1 Air intrusion into the hydraulic system is the main reason for noise 2 The relief valve is unstable, such as due to the improper combination of the slide valve and the valve hole or the contact of the cone valve and the seat is stuck by dirt, the damping hole is blocked, the spring is crooked or fails to make the spool stuck or move in the valve hole, causing system pressure fluctuation and noise. 3 Improper adjustment of the reversing valve causes the spool of the reversing valve to move too fast, resulting in reversing impact, resulting in noise and vibration. 4 Mechanical vibration, such as long tubing, elbow more and not fixed, when the oil flow through, especially when the flow rate is high, easy to cause pipe shaking; The rotating part of the motor and hydraulic pump is unbalanced, or the alignment is not good during installation, or the coupling is loose, etc., which can produce vibration and noise.
