Angola hydraulic cylinder,automatic reversing cylinder manufacturer,automatic reversing cylinder(Angola automatic reversing cylinder,produced by Hengyu Hydraulic Cylinder Factory)
automatic reversing cylinder are widely used in Angola,because of long service life,smooth movement,high work efficiency.So our company has designed automatic reversing cylinder for customers from Angola.
When the piston speed of the automatic reversing cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the automatic reversing cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
The viscosity of the working oil used in the automatic reversing cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.
After chrome plating of the piston rod of the automatic reversing cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.
When the long-stroke automatic reversing cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in automatic reversing cylinder head seal damage, oil leakage, and piston sleep in the automatic reversing cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the automatic reversing cylinder; The piston and the piston rod are connected with a spherical joint.
How to disassemble the cylinder?
Generally speaking, it is not difficult to disassemble the hydraulic cylinder, as long as you are careful, but you often encounter some small trouble in the disassembly process, because the disassembly process is not correct. In fact, this can be avoided, as long as you follow below points. 1. Before removing the hydraulic cylinder, the hydraulic circuit should be relieved of pressure, otherwise, when the oil pipe connected with the cylinder is loosened, the high-pressure oil in the circuit will be rapidly ejected. When the hydraulic pressure comes back, the handwheel or pressure regulating screw at the relief valve should be loosened first, so that the pressure oil is unloaded, and then the power supply or power source is cut off, so that the hydraulic device stops running. 2. Disassembly should prevent damage to the top thread of the piston rod, the oil thread and the chrome layer on the piston rod surface.
What are the connection methods of the hydraulic cylinder? The connection modes of the cylinder and the actuator are earring connection, hinge shaft connection, thread connection, etc. The connection modes of tubing and cylinder are threaded connection, flange connection, etc.
